Podcasts about Food web

In this episode of the How to Protect the Ocean podcast, host Andrew Luan discusses the significant decline in the population of common murres, a seabird species in Alaska, which has seen about half of its population die off—approximately 4 million individuals—since the marine heat wave known as "the blob" occurred from 2014 to 2016. The primary reason for this drastic decline is linked to the effects of the heat wave on the marine food web rather than direct thermal stress on the birds themselves. The heat wave caused shifts in the availability of food sources, leading to starvation among the murres. The study highlighted that the murres rely heavily on oceanic food supplies, and disruptions in these supplies can have devastating impacts on their populations. Research conducted by the University of Washington and the U.S. Fisheries and Wildlife Service revealed that the murre population in the Gulf of Alaska dropped by half, while in the eastern Bering Sea, the decline was even steeper at 75%. The study emphasized that without a recovery in the prey populations, the murres are unlikely to rebound, indicating a potential tipping point in the ecosystem that could prevent recovery for this species and others reliant on the same food sources. Overall, the episode underscores the importance of understanding and funding research on marine ecosystems to address the long-term impacts of climate change and marine heat waves on wildlife populations.

Lake Michigan is teeming with life. But over time, its food web — from the smallest plankton to the largest fish — has been impacted. Overfishing and waves of invasive species have taken their toll. Now, climate change is flexing its muscles in the Lake Michigan ecosystem. On land, we've felt and seen it during what's been the warmest winter on record.

How can some people recall random facts so easily? It may have to do with what else they remember about the moment they learned the information. Also, in Kenya, an invading ant species pushed out ants that protected acacia trees. That had cascading effects for elephants, zebras, lions, and buffalo.A ‘Jeopardy!' Winner Studied How Trivia Experts Recall FactsWhen contestants play “Jeopardy!,” it can be amazing to see how quickly they seem to recall even the most random, obscure facts. One multi-time “Jeopardy!” contestant, Dr. Monica Thieu, noticed something interesting about the way that she and her fellow contestants were recalling tidbits of information. They weren't just remembering the facts, but also the context of how they learned them: where they were, what they read, who they were with. Hypothesizing that for trivia superstars, information was strongly tied to the experience of learning it, she put that anecdotal evidence to the test. The results of her research were recently published in the journal Psychonomic Bulletin & Review.SciFri producer Kathleen Davis talks with Dr. Thieu, a psychology researcher at Emory University, and Dr. Mariam Aly, assistant professor of psychology at Columbia University, and a co-author of the new study. They discuss the psychology of trivia, how to get better at it, and why some people seem to be much more adept at recalling fun trivia facts than others.See if you can beat a "Jeopardy!" champ on our website!How One Invading Ant Species Sent Ripples Through A Food WebWhen people talk about the interconnectedness of nature, the usual example involves a little fish that eats a bug, a bigger fish that eats the little fish, and an even bigger fish at the top of the chain. But in reality, the interconnected relationships in an ecosystem can be a lot more complicated. That was certainly the case in a recent study, published in the journal Science, which describes how the arrival of an invasive ant species changed the number of zebras that get eaten by lions on the Kenyan savannah.The unwelcome ant is known as the big-headed ant. It's on a list of top 100 invasive species around the world. When it arrived on the African savannah, the ant newcomer muscled out a native ant species known as the acacia ant—which, though tiny, was able to help defend acacia trees from being grazed upon by elephants (picture getting a trunkful of angry ants while snacking).With the trees undefended, hungry elephants feasted, resulting in fewer trees on the savannah and more open space. That made the hunting environment less favorable to stealthy lions, and more favorable to fleet-footed zebras. But to the surprise of the researchers involved with the study, that didn't mean hungrier lions. Instead, the lions shifted their hunting from targeting zebras to targeting buffalo instead.Dr. Jacob Goheen and Douglas Kamaru of the University of Wyoming join guest host Sophie Bushwick to describe their research, and how a small ant can have a big effect on an ecosystem.Transcripts for each segment will be available after the show airs on sciencefriday.com.

A team of scientists in Ecuador is on a mission to describe new-to-science tarantula species to help secure conservation protections. And, undergraduate researchers pasted striped capes onto termites' backs to see if a well-known warning sign would fend off predators.Protecting The ‘Satan' Tarantula and Other Lovable Giant SpidersA team of scientists in Ecuador is on a mission to find and describe species of an understudied, often unpopular group of critters: mygalomorphs, a group of large, stocky spiders that includes tarantulas. In late 2023, two of these researchers published a paper in the journal ZooKeys describing two new-to-science tarantula species, including one named Psalmopoeus satanas—affectionately called the “Satan tarantula” because of its erratic behavior.Tarantulas are understudied in Ecuador, and there are many species left to describe. They're also threatened by mining, agriculture, and the illegal pet trade. That's what led Pedro Peñaherrera-R., a researcher at Universidad San Francisco de Quito to found the Mygalomorphae Research Group. Its members are working to describe these spiders and secure conservation protections before they possibly disappear.Producer Rasha Aridi talks with Peñaherrera-R. and his co-author and fellow group member Roberto José León about how the Satan tarantula earned its name, how they discover and classify spiders, and why we should all show spiders a little more love.If Termites Wore Stripes, Would Spiders Still Eat Them?The animal kingdom is filled with colors and patterns. Sometimes, those colors are to signal to members of an animal's own species, in a mating display for instance. In other cases, a bright color or vibrant pattern serves as a warning to potential predators—a signal saying “don't eat me, I'm toxic.” That type of warning coloration, known as aposematism, can be seen in the bright colors of a poison dart frog, or the black, white, and yellow stripes of a monarch butterfly caterpillar.Bigger animals, like birds, are known to consider that sort of warning signal when hunting. Researchers at the University of Florida were interested in whether jumping spiders might also take that sort of striped warning coloration into account when choosing their prey. To find out, they applied tiny striped capes to the backs of laboratory termites to study whether those stripes affected the behavior of hungry jumping spiders. They found that while the test spiders did notice the striped termites more than termites wearing solid colors, the spiders were less likely to attack striped termites when given the chance to do so.Behavioral ecologist Dr. Lisa Taylor joins Ira to discuss the purpose of the project—and former lead undergraduate researcher Lauren Gawel describes the challenges of trying to get termites to dress up as superheroes.Transcripts for each segment will be available after the show airs on sciencefriday.com.

We're bringing bloater back...Go ahead and tell them skinny fishes that...'Cause every inch of bloater's perfect from the bottom to the top (sha-wop, wop). We've got a great episode for you about an amazing fish with a rich history in the Great Lakes: the Bloater! Brian Weidel with the U.S. Geological Survey's Great Lakes Science Center and Dimitry Gorsky from our Great Lakes Fish and Wildlife Conservation Office are guests.

In our last episode we explored the challenges that a global food system can have for local communities.  On this episode of Root Words we'll talk with Ken Meter, president of Crossroads Resource Center and Philip Ackerman-Leist farmer, author, and Vermont Farmers Food Center board member, as we explore the concept of a community Food Web and the benefits of this local alternative. To start us off, let's go back to our conversation from the last episode with Ellen Kahler, Executive Director with Vermont Sustainable Jobs Fund, and member of the Governor's Commission on the Future of Vermont Agriculture, where she helped create Vermont Farm to Plate, the state's food systems development plan.   Ellen says that the Covid-19 pandemic caused major disruptions in the fragile global food system.  Creating an alternative supply chain will need to be a community effort played out region by region, but communities don't need to feel isolated while doing this work.  Food systems analysts like Ken Meter can help provide perspective.  In 2019, Ken conducted and wrote VFFC's Market Study which helped guide its strategic planning in 2020. Ken Meter is the president of Crossroads Resource Center, a non-profit organization that works with communities to foster democracy and local self-determination. His local economic analyses have promoted local food networks in 140 regions, 40 states, two provinces, and three tribal nations.  His recent book, Building Community Food Webs, is an inspiring collection of stories about how communities transformed their food systems and local economies.    A community food web builds health, wealth, connection, and capacity within the local community.   Ken believes that a community food web is largely a relational network, and that the strength of these relationships relies on trust.  Philip Ackerman-Leist is a farmer, former food systems professor, VFFC board member, and author of Rebuilding the Foodshed: How to Create Local, Sustainable, and Secure Food Systems. While working with partners in the food web, Philip puts his faith in trust. Tension between available resources and the vision for recreating a relational food web can create slow, stable, and resilient change, but tension between communities of people in a food web can increase inequity and erode trust.   Ken Meter feels that the food system we have now creates wealth for some at the expense of others, but a relocalized community food web can be a vehicle for restoring trust and addressing injustice.    On the next episode of Root Words we'll take a closer look at the filaments that bind a community food web as we explore Restoring Relationships.  This episode was produced by Stephen Abatiell and Julia Anderson.  Special thanks to Ellen Kahler, Ken Meter, and Philip Ackerman-Leist.

The profit-hungry agribusiness empire of the 20th century institutionalized farming practices that continue to degrade soils across the U.S. and globally. We face a fork in the road: collapse or regeneration? The good news is that we know what we need to begin an agricultural and ecological renaissance – a literal rebirth.  Biologist Ann Biklé and geologist David Montgomery share one of the good news stories that show how the solutions residing in nature surpass our conception of what's even possible. Featuring David R. Montgomery, a Seattle-based MacArthur Fellow and professor of Geomorphology at the University of Washington and the author of award-winning popular-science books that have been translated into nine languages, is an internationally recognized geologist who studies landscape evolution and the effects of geological processes on ecological systems and human societies. Anne Biklé, a biologist, science communicator, and public speaker, investigates and writes about connections between people, plants, food, health, and the environment. Her work has appeared in magazines, newspapers and radio, and her soil-building practices have been featured in independent and documentary films.

The majority of the omega 3 fatty acids in our diet get their start in a tiny, unassuming organism: the phytoplankton. Phytoplankton are the primary producers of the oceanic food web, converting sunlight into energy. But what happens when warming oceans change the dynamics of energy availability? We chat about this and more with MS student in Marine Resource Management Becky Smoak.

Can genes in single species act as keystones in ecosystems? What is AOP2, and how does it affect community composition and persistence? In this episode, we talk to Matt Barbour, a professor at the University of Sherbrooke, about “keystones” in biology. You're probably familiar with the keystone species concept, but Matt's research focuses on whether genes can play a similarly fundamental role in an ecosystem. In an incredible set of experiments, Matt and his colleagues used simple experimental food webs to find that the stability of these miniature complex systems was strongly associated to the genotype at one specific locus in the plant, Arabidopsis thaliana, called AOP2. The particular genetic variant led to complete breakdown of community stability, imbuing that gene with a keystone-like function. We talk to Matt about his recent publication in the journal Science and discuss how results from his simple lab setup relates to keystone effects in natural communities. Cover art: Keating Shahmehri

With Lyla June Johnston & Michael Ableman. We're going to kick off the season by getting our feet down in the soil to talk about agriculture! Our two guests present a compelling vision of how agricultural systems offer humans a deeper sense of purpose that goes beyond the provisioning of food.This is because farmers and producers often spend their days immersed in the lifeworlds of the land — in the delicate stalks of green, the humming of pollinators, the beating of bird feathers and the pungent smells of sprouting crops. Their survival depends on them paying very close attention, seeing and interpreting the world through other eyes, and by doing so a whole other human psychology unfolds.Lyla June Johnston is an indigenous scholar, public speaker, artist, and poet of Diné, Tsétsêhéstâhese and European lineages. Lyla studied human ecology at Stanford and is writing her PhD on Indigenous Food Systems Revitalization. She describes millennia-old methods of agriculture that were ingeniously designed to harness nature's flows, ranging from expansive clam gardens in the Pacific Northwest to the American grasslands. You'll hear about governance systems and worldviews required to cultivate such abundant landscapes and how we can restore our relationship to farming and food.Michael Ableman has been an organic farmer for over 50 years and is considered one of the pioneers of the organic farming and urban agriculture movements. He founded North America's largest urban farm located in Vancouver, that employs people who have been impacted by long term addiction and mental illness. This experience has proven to Michael how farming can support profound healing, and with us he shares his intimate approach to farming, dropping hints as to how you can also listen to the land.Episode Website Link: lifeworld.earth/episodes/unexpectedagricultures Show Links:Lifeworlds Resource Page: AgricultureArchitects of Abundance: Indigenous Food Systems and the Excavation of Hidden HistoryCultivating Food Forests with Indigenous WisdomLyla's websiteMichael's websiteSole Food Street FarmsLook out for meditations, poems, readings, and other snippets of inspiration in between episodes.Music: Electric Ethnicity by Igor Dvorkin, Duncan Pittock, Ellie Kidd & The Rising by Tryad CCPLPhoto Credit: Rob Kesseler See acast.com/privacy for privacy and opt-out information.

In this special rebroadcast of the first of Changing Waters' 2019 series on the plight of southern resident killer whales, National Fisheries Conservation Center's Deputy Director Julia Sanders interviews NOAA researcher Laurie Weitkamp about the food web effects caused by recent heat waves in the Pacific ocean, including the "warm blob." These changing conditions have caused major disturbances all the way up the food web: starting with microscopic plankton and ending with our beloved Orca whales. Learn more about what's happening in our changing waters as temperatures rise and fisheries face abrupt disruptions -- including the Chinook salmon that southern resident killer whales rely on.

Right now, scientists are on a ship taking samples and measurements of the Great Lakes. They're trying to determine how the lakes will fare this year and watching for trends.

Right now, scientists are on a ship taking samples and measurements of the Great Lakes. They’re trying to determine how the lakes will fare this year and watching for trends. One trend, the warming climate, could mean changes for the base of the food web in the lakes. But, the researchers are not yet sure what those changes might be.

Hayley Glassic, a graduate student in the Department of Ecology at Montana State University, discusses the need for a healthy work-life balance and her research on the Yellowstone Lake food web.

Climate change, pollution, development and other stresses have accelerated the decline of reef ecosystems across much of the world’s oceans in recent years.  Large predators such as sharks, mackerels, barracudas, jacks and others that formerly fed around reefs have had to venture outside their normal migratory routes in search of suitable alternatives. According to a […]

Jani Sparks, Stable Isotope Specialist at the Purdue University Stable Isotope Facility, discusses the process of analyzing samples for Professors at Purdue University. To begin, isotopes can be thought of as chemical tracers. Carbon-14 is not a stable isotope, which makes it useful for radiocarbon dating. However, the Stable Isotope Lab looks for differences between stable isotopes over time, such as the relationship between Carbon-12 and Carbon-13. A variety of isotopes exist and common light, stable isotopes are referred to as “CHONS” - carbon, hydrogen, oxygen, nitrogen, and sulfur. Stable isotopes of these elements are the most common to be analyzed in the Purdue University Stable Isotope Facility. An Isotope Ratio Mass Spectrometer is the instrument used by Dr. Sparks to analyze gas samples. Applications of the Stable Isotope Lab include looking at food webs and determining trophic levels of different species. By analyzing bones or hair using carbon and nitrogen stable isotopes, Dr. Sparks can tell whether or not someone is a vegetarian. Archaeologists can analyze bones to determine where animals may have migrated from using various stable isotopes. Additionally, national labs like the FDA make use of stable isotopes to determine whether substances such as honey, lemon juice, and maple syrup are pure or adulterated. Dr. Sparks advises high school students to check out stable isotope facilities, either at Purdue or other large Universities, and recommends that interested students seek out a Stable Isotope courses.

Under the canopy of an ancient fern forest near the border of Arizona and New Mexico a colossal crocodile-like reptile took a bite out of an even larger, toothy giant. The attack failed and the victim limped on to fight another day, until its carcass was finally pillaged by another scaly monster and smaller, pickier scavengers. Studying bones collected over a century ago, scientists are now able to reconstruct these scenes from the ancient Wild West using new digital tools familiar to fans of C.S.I.

New Zealand and Australian scientists head off on a six-week voyage to Antarctica to study top predators in the Southern Ocean.

Researchers lead by Hans-Dieter Sues from the Smithsonian Institution described a wealth of new giant, long-necked dinosaur material from Western Asia (Uzbekistan). They were able to reconstruct what the brain looked like and discvered the dinosaur, part of the lineage called "titanosaurs", is closely related to animals from the far East of Asia, places like China and Laos. They decided there wasn't enough of the giant to give it a name, but they know it and its relatives were able to make a living across the diverse enviroments of Asia 90 million years ago. This is further evidence that tintanosaurs were successful for much of the Age of Dinosaurs both on the Northern and Southern continents. The study: Sues, H.-D., A. Averianov, and R. C.

To conjure up extinct environments, museums, books, and documentaries rely on art to show vanished animals revitalized in their ancient surroundings. This type of educational reconstruction is called Paleoart (or Palaeoart for the UK inclined) and you can't help but look at an image of a roaming Tyrannosaurus rex without wondering, "How much of that is real?" How do we know its bulk, its color, its environment, or its behavior? Where does the science start and the art (and hypothesizing) begin? Julius Csotonyi, a Candian paleoartist, sat down with us to discuss how he assembles his images which are on display in natural history museums across North America and fill his recently published book, The Paleoart of Julius Csotonyi. A single landscape by Julius is a blend of the latest knowledge from paleontologists, zoologists, paleobotanists, geologists, and geochemists, and as new information is learned, he is ready to update his paintings and present the world with a more accurate glimpse into the ancient past.

When we think of paleontologists, we think of people hunkered down with bones, teeth, and shells studying the preserved body parts of dead organisms. But animals leave behind more than just their skeletons. As they walk they can leave behind footprints, as they eat they can leave behind bite marks, and as they finish eating they leave behind…well…what comes from the behind. The study of the traces of past behavior is called ichnology and Dr. Tony Martin (@Ichnologist) and author of “Dinosaurs without Bones” is with us to reveal all the amazing insights a paleontologist can learn from the fossil record, even when there aren’t any bones! He takes us through a wandering heard of sauropod dinosaurs, into the burrow of the dinosaur Oryctodromeus, and across the mudflats of an amphibian-dominated Alabama. These animals may be extinct, but their traces bring them back to thundering life in this episode of Past Time!

When we think of iconic dinosaurs, like T. rex with its massive head full of teeth, and Parasaurolophus crowned with a gigantic, tube-like horn, we’re thinking of the features of adult dinosaurs. But we know from looking around today that animals change a lot from birth to adulthood. Did T. rex always have a massive maw and Parasaurolophus a huge crest? How quickly did they grow in? What were they used for? To really understand the biology of these titans, paleontologists need to study baby dinosaurs to connect the dots from tiny hatchling to adult dinosaur. Unfortunately, the fossils of dino-toddlers are few and far between because their skeletons are usually pretty delicate. In this episode we discuss the improbable discovery of a baby Parasaurolophus with Dr. Andy Farke, a paleontologist from the Raymond Alf Museum and Webb Schools in Clermont, California. Dubbed “Dinosaur Joe”, the young dinosaur was found and studied by young, high school scientists from the Webb School. The high school scientists were part of the team that revealed the six-foot-long animal was only one-year-old and had a little nubbin of a what would become that spectacular Parasaurolophus crest.

Marine mammals are fascinating beasts. Whales, manatees, seals, otters...they've all gone back to the water and in the process evolved all kinds of spectacular adaptations to make a living in a soggy setting. Toothed evolved an ability to “see” the underwater world around them using echolocation - basically sonar - to track prey with high-pitched sounds and echoes. A 23 million years old fossil from South Carolina called Cotylocara shows toothed whales could echolocate early in their evolutionary history. A more surprising adaptation to life in the water was preserved with another new whale fossil from California. Called Semirostrum, the new whale has a huge underbite and long chin which was probably used as a sensitive probe to track down buried prey. Whales in the water are interesting, but not unexpected. Our final study examines how SLOTHS adapted to life in the ocean. Thalassocnus was a relative of giant ground sloths, a solidly terrestrial group of animals. A recent study showed how Thalassocnus gradually acquired thickened bones, a trait that has been observed in nearly every mammal that has gone back to the water. Even if it’s a weird animal to imagine clawing through the water, it adapted to that lifestyle in exactly the way paleontologists expect any mammal to get back to the water!

Over 400 million years ago the oceans were teeming with life, but it didn’t look much like what you see at the aquarium or in Finding Nemo. Instead of colorful fish flitting through coral reefs, the ancient seas had giant, shelled squids darting past the icons of the early ocean: The Trilobites! Journey back to the Late Ordovician sea with Dr. Brenda Hunda, Curator of Invertebrates at the Cincinnati Museum Center. Dr. Hunda has spent her career carefully documenting the changes in trilobites in the remarkable rocks near Cincinnati, Ohio. Trilobites were spectacularly diverse early arthropods (the group that includes crustaceous, insects, and arachnids) that adapted to the ever-changing seas, by swimming through the water, scooting along the ocean floor, and burrowing through the mud for their 300 million year reign. Our journey through the ancient Queen City features the musical talents of two great Cincinnati-area bands: The Cincinnati Dancing Pigs and Jake Speed and the Freddies!

50 million-years ago, the heir to Tyrannosaurus stalked the forests of ancient Europe and North America, snapping up the tiny ancestors of horses, cows, and wolves in its colossal meat-cleaving beak. Gastornis was a six-foot-tall, flightless bird and the king of the food chain...or that’s what we thought. For decades paleontologists looked at the huge, parrot-like head and thought the giant bird must be a carnivore, but a recent, exhaustive study drew on molecular evidence, anatomical evidence, and ecological evidence to show Gastornis was a giant herbivore! The former terror bird likely used that massive beak to crack open the abundant seeds and leaves that would have littered the forest at the beginning of the Age of Mammals. Tune in to Past Time to learn how the fossil Terror Bird became Big Bird! The post Quick Bite: From Terror Bird to Gentle Giant appeared first on Past Time Paleo.

Meet Alienochelys selloumi, a giant, snorkel-nosed turtle with powerful, shell-crushing plates in its massive beak! The distant relative of the largest turtle alive today, the leatherback sea turtle, Alienochelys swam the ancient ocean of North Africa at the very end of the Age of Dinosaurs (the Late Cretaceous). It was found in the same rocks as Ocepechelon, the whale turtle discussed in our first Quick Bite back in July. There were a lot of giant, goofy, snorkel-snouted turtles in Cretaceous Morocco! When Alienochelys' discovery was announced, another paper was published describing fossilized pigment molecules that showed many marine reptiles, including a 55 million-year-old leatherback sea turtle, were dark in color, an adaptation we see in many modern swimming vertebrates. It's time to pick a new-favorite fossil turtle with Past Time! The post Quick Bite: The Alien Turtle and Ancient Color appeared first on Past Time Paleo.

Little people! Giant reptiles! Towering elephants! Huge birds! It sounds like the stuff of literary and box-office gold, but this Middle-Earth-like world actually existed 17,000 years ago on Flores, an island near Indonesia. Homo floresiensis, or "The Hobbts", only stood three feet tall but they cast a huge shadow over the story of human evolution. In 2004 fossils of the small, big-footed hominins were discovered and they have challenged paleoanthropologists, like this episode's Dr. William Jungers, to reconsider many hypotheses of human origins including which species left the continent and how we're all related. Once thought to just be small versions of Homo erectus, the hobbits may have much more ancient ancestors, posing more questions for the fossil record to answer as the human story becomes even more complicated...and interesting!

Last episode we featured Lythronax, the oldest-known North American tyrannosaur and a close relative of Tyrannosaurus rex. But tyrannosaurs weren’t the only big carnivores to tromp through the Mesozoic of North America. Before the tyrant lizards were huge, there was another giant terrorizing the American West: Siats! Named for a Ute mythological giant, Siats was a bus-sized carnivore in the middle Cretaceous of Utah (99 million years ago). The giant had close relatives - the neoventors - on almost all the continents. This is a bit of a mystery because the continents were getting spread out by 99 million years, making it tough to explain how the neovenators conquered the world. In North America, this global dynasty replaced another family of giants: the carcharodontosaurs which included Acrocanthosaurus the top carnivore of the Early Cretaceous of Western and Eastern North America. The discovery of Siats shows different lineages of carnivorous dinosaurs could get really big and T. rex is just the last monarch to fill the giant carnivore niche in North America. It’s another toothy, terrifying tale on Past Time! The post Quick Bite: The Giant Before the Tyrant! appeared first on Past Time Paleo.

Tyrannosaurus rex is a dinosaur celebrity, a villain in most dinosaur movies and documentaries, but where did the massive beast come from? On November 6, 2013, a team of paleontologists including our expert in this episode, Dr. Randy Irmis from the University of Utah and the Natural History Museum of Utah, published two new skeletons of Tyrannosaurus’s close kin: Teratophoneus and Lythronax. The skeletons reveal Tyrannosauridae (T. rex’s family) was diverse 80 million years ago with different species living in different parts of Western North America. The new genus Lythronax is the oldest member of the Tyrannosauridae even though its anatomy closely resembles the last species of tyrannosaurid, T. rex. A massive sea divided Western North America, called Laramidia, from Eastern North America, called Appalachia. Laramidia was a long, skinny continent that ran from Alaska to Baja California. In general, in modern ecosystems, the larger the land-mass, the more species can live on it. Laramidia was one-tenth the size of the continent of North America, but it supported more species of large animals than the complete continent of North America today! Geologists, paleontologists, and ecologists aren’t sure how this was possible so they continue to search for new fossils and the origins of the North American ecosystem. New fossils, like Teratophoneus and Lythronax show us there are still more questions to answer using the fossil record! Sic semper tyrannis!

Fossils are the raw materials of paleontology, but if we want to know how an animal moved or ate, paleontologists, like Dr. Paul Gignac, need to study living animals, too. Dr. Gignac studies crocodylians, measuring their bite forces across species and as they grow up to figure out how the strongest bite in nature evolved. Using techniques drawn from mechanical engineering and physiology, Dr. Gignac discovered the relationship between body size and bite force in crocodiles, and developed equations to calculate those forces. Then he used these equations to calculate the bite forces of giant extinct crocodiles like Deinosuchus. He also studied the bite marks left by the sickle-clawed dinosaur Deinonychus to calculate dinosaur bite forces. There are so many questions to ask about extinct animals but there's also a lot left to learn about their living descendants! The lines between scientific disciplines get blurred and the questions just get more interesting in this episode of Past Time!

Whales are spectacularly specialized mammals that seem perfectly adapted to their marine habitat. Plenty of other mammals have gone back to the water, but whales take it to a whole new level. No back legs, weird ear bones, noses on top of the head. What could the land-based ancestor of whales possibly looked like? Is there a fossil record of walking whales? In this episode we discover whales belong to the hooved animal group called Artiodactlys and their closest relatives, according to molecular comparisons, are hippos! But hippos and extinct fossil whales don't look very much alike. How did paleontologists, like our guest Dr. Marueen O'Leary, figure out the origins of whales, and how will they figure out the origins of hippos? As always, there are always more questions to answer when we start digging into the fossil record! The post Episode 7: Walking through Whale Evolution appeared first on Past Time Paleo.

Mammals were scrambling around during the Age of Dinosaurs and they're usually seen as small, shrew-like animals waiting for their chance to become diverse. But recent research, including three new fossils discovered in 160 million-year-old rocks from China, show our mammalian cousins were ecologically specialized creatures. Arboroharamiya was climbing through the trees while Megaconus scrambled along the ground, and Rugosodon lead the way for the diverse radiation of mammals called Multituberculates. In this episode, Matt tries to show Adam why these new, tiny mammals are so interesting and where they fit into the mammalian tree of life.

The fossil record is pretty patchy. Most discoveries are tooth fragments, chunks of shell, or isolated slivers of bone and paleontologists are trained to eke out as much information from these precious fragments as they can. But some fossil deposits preserve more than just bones and teeth. Called "Lagerstätte" some rare deposites preserve traces of difficult-to-fossilized soft-tissues like feathers and fur. Some even preserve an animal's last meal before it entered the fossil record. In this episode of Past Time, Matt and Adam discuss Messel, a German fossil site that is one of the best examples of the biological and ecological knowledge preserved in these rare Lagerstätten deposits. Early bats, mini horses, and galloping crocodiles once roamed this extinct jungle in the heart of Europe. The exquisite preservation at Messel lets paleontologists travel back to this exotic ecosystem to tease out connections between the beginning of the Age of Mammals and modern tropical environments.

Humans are weird animals. We walk around on two legs, we have big brains...and we like to throw things at each other. Did all this happen in a gradual march to Homo sapiens? In this episode of Past Time, Adam and Matt talk to Dr. Susan Larson, an expert on the anatomy of living and extinct apes. Dr. Larson and Matt will try to convince Adam that mammalian and primate evolution is actually pretty interesting stuff. Dr. Larson's research introduced new wrinkles to the smoth transition from a chimp-like ancestor to us. Her work shows our close bipedal ancestors - like "Lucy" the Australopithecus and "Turkana Boy" the Homo erectus/Homo ergaster - had very different shoulder blades than ours that limited their ability to rotate their arms. This arrangement would have made throwing difficult for Homo erectus and you would have left him on the bench for the playoffs. The evolution of pitching in recent human ancestors shaped our modern anatomy and is part of what makes us human! The post Episode 5: Throwing in Human Evolution appeared first on Past Time Paleo.

Meet Ocepechlon, one of the strangest turtles to ever paddle the open ocean in our first Past Time Quick Bite! This new species was announced a few weeks ago based on a lone, beautifully preserved skull from the Late Cretaceous (end of the Age of Dinosaurs) of Morocco. The gigantic animal had a long, tubular snout that the discoverers have interpreted as an adaptation to suction feeding, a specialized feeding method used by lots of aquatic animals including some types of whales. But this would be the first known suction-feeding sea turtle. Ocepechelon also has its nasal opening placed high on its head, between its widely spaced eyes, just like the spout of a whale. Based on the researcher’s analysis, its closest relatives include the gigantic leatherback sea turtle, a huge, beautiful animal that is critically endangered. In case you were cruising for a new favorite, bizarre sea turtle, look no farther than Ocepechelon!

Sauropod dinosaurs, the long necked creatures like Apatasaurus and Brachiosaurus, were the biggest animals to ever leave a footprint on the Earth. They were the size of whales, but didn't have the luxury of water to help them support their bulk! The massive size of sauropod dinosaurs intrigued Dr. Michael D'Emic and he has been scrutinizing their bone structure and relationships to figure out how these saurian giants managed to get around and consume enough food to keep growing.

We all know what a reptile is, right? Scaly, sprawling legs, cold blooded. But where did they come from and how are they all related to one another? What makes a lizard different from a crocodile? In this episode Adam teaches Matt about the different lineages of reptiles alive today and some of the mysteries biologists and paleontologists are still wrestling with in the reptile family tree. Spoiler alert: Turtles are the black sheep of the family. The post Episode 3: What is a Reptile? appeared first on Past Time Paleo.

What is a dinosaur? What is a bird? They're related somehow, but how does a paleontologist figure out how close Velociraptors and penguins are in the dinosaur family tree? In this episode of Past Time, Matt and Adam talk to Dr. Alan Turner, an expert on fossils from the dino-bird transition to figure out which animals are most important in sorting out this incredible evolutionary story.

To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their effects some time in the future, and we will be looking at the legacies that we leave to future generations. We move on to consider our own demise, and ask what exactly it is that we think we will be leaving for those who follow.

The experiments presented in this thesis elucidate selected interactions between the phytoplankton, the zooplankton and the microbial food web in aquatic ecosystems. The objective is to provide a mechanistic understanding of classic general ecology topics including competition, predator-prey relations, food web structure, succession, and transfer of matter and energy. Special relevance is attributed to the role of mixotrophic organisms, marine cladocerans, and gelatinous mesozooplankton. Although they may contribute substantially to plankton composition they have thus far been neglected in common ecosystem models. All experiments were based on enrichment with nutrients and organic compounds. Enrichment with nutrients and organic compounds that influence overall system productivity is one of the most pervasive human alterations of the environment and profoundly affects species composition, food web structure, and ecosystem functioning. In order to predict the consequences of such enrichment, a better understanding of the impact that trophic structure has on community dynamics and ecosystem processes is required. The presented thesis consists of two studies. The first study includes three experiments in which I investigated the role copepods, cladocerans and doliolids play in plankton interactions. Copepods, cladocerans and doliolids are major mesozooplankton groups in marine systems. The first experiment (Katechakis et al. 2004) showed that copepods, cladocerans and doliolids have different food size spectra and different assimilation efficiencies. According to my experiment, copepods actively select for larger food items, whereas cladocerans and doliolids passively filter medium-sized and small food items, respectively, with doliolids being the only group that feeds efficiently on bacteria and picoplankton. The results illustrate that food niche separation enables copepods, cladocerans and doliolids to coexist. In addition, they emphasize the fact that doliolids are favored in low nutrient environments, characterized by small food items, whereas cladocerans and copepods have competitive advantages at moderate and high nutrient supplies, respectively. Furthermore, copepods obviously utilize ingested food best, gauged in terms of produced biomass, followed by cladocerans and doliolids, which suggests that the different mesozooplankton have different impacts on energy transfer efficiency within the food web. In the second experiment (Katechakis et al. 2002), I investigated how copepods, cladocerans and doliolids directly influence the phytoplankton and the microbial food web over a longer period of time by grazing. Furthermore, I investigated how they indirectly influence the system's nutrient dynamics through "sloppy feeding" and their excretions. According to my experiment, in the long run, doliolids and cladocerans promote the growth of large algae whereas copepods shift the size spectrum towards small sizes with different consequences for food chain length. Doliolids, cladocerans and copepods also affect the microbial food web in different ways. Size-selective grazing may lead to differences in the nanoplankton concentrations. These in turn can affect bacterial concentrations in a trophic cascade. My findings offered the first experimental evidence for the occurrence of top-down effects in marine systems. Although top-down explanations of phytoplankton size structure had been acknowledged for limnic systems before, they had not been attempted for marine systems. In the last experiment of this series (Katechakis and Stibor 2004) I sought to complement the knowledge about the feeding behavior of marine cladocerans. Marine cladocerans are difficult to cultivate in the laboratory. Therefore, the three cladoceran genera found in marine systems, Penilia, Podon and Evadne, had never before been compared under similar conditions. Existing studies with single cladoceran genera were to some extent contradictory. My experiments indicate similar feeding characteristics for Penilia, Podon and Evadne, that is to say, similar food size spectra, clearance and ingestion rates. However, Evadne obviously has problems feeding on motile prey organisms. The results generated by my first study have been summarized and their importance has been hypothetically extended to ecosystem level by Sommer et al. (2002) and by Sommer and Stibor (2002). My second study includes two experiments that refer to the ecological role of mixotrophs in aquatic systems. Mixotrophic organisms combine phototrophic and phagotrophic production dependent on the availability of light and nutrients. Although they are common in aquatic systems, their function for nutrient cycling and as a link to higher trophic levels has never before been examined. In my first experiment (Katechakis et al. 2005) I investigated if mixotrophs influence energy transfer efficiency to higher trophic levels differently than predicted for purely phototrophic organisms. My results indicate that compared to phototrophic specialists mixotrophs may enhance transfer efficiency towards herbivores at low light conditions and in situations when limiting nutrients are linked to bacteria and to the picoplankton. Additionally, the results suggest that mixotrophs may have a stabilizing effect on variations in trophic cascade strength caused by perturbations to light and nutrient supply ratios. My second experiment (Katechakis and Stibor 2005a) served as a first step towards analyzing if the results gained from the first experiment have any ecological relevance in situ, that is, if mixotrophs in nature-like communities can gain enough importance to relevantly influence transfer efficiency and system stability. Competition experiments revealed that mixotrophs may invade and suppress plankton communities that consist of purely phototrophic and purely phagotrophic specialists at low nutrient conditions while high nutrient supplies prevent mixotrophs from successfully invading such communities. In systems where mixotrophs suppressed their specialist competitors they indeed had a habitat-ameliorating effect for higher trophic levels, gauged in terms of plankton food quality.

What does DAN Europe advise for diving after you receive a Vaccination? Listen to what we found out. We also have received word of an Ohio Drive Quarry that is changing ownership. What? Where are the missing episodes? Don't worry. They are on their way. We have another significant format change coming in the next few weeks and wanted to get the current episode out before then. -- there are a few sections where Mack's audio is a little clipping. We did clean it up as much as we could. It is still listenable, but does stutter and break a few times. The new format change should help address it or turn it into a big dumpster fire. Either way it could be entertaining. -- (0:39) **Introduction ** (1:13) **River water level and dead salmon** (2:35) **Scuba in the News ** (2:39) **Diving After Your COVID-19 Vaccination: Guidelines** https://www.daneurope.org/readarticle?p_p_id=web_content_reading&p_p_lifecycle=0&p_p_mode=view&p_p_col_id=column-1&p_p_col_count=1&p_r_p_-1523133153_groupId=10103&p_r_p_-1523133153_articleId=14891675&p_r_p_-1523133153_articleVersion=1.0  (07:33) **Calls to end mutilation, inhumane treatment of sharks and rays in SA** https://www.abc.net.au/news/2021-04-08/outrage-as-sharks-and-stingrays-left-mutilated-in-sa/100054722  (12:06) **Derek in Melbourne - Local Diver Perspective - ** (18:29) **Scientists Concerned About the Bottom of the Food Web in the Great Lakes** https://www.greatlakesnow.org/2021/04/scientists-bottom-food-web-great-lakes/  (27:07) **Teen designs, builds underwater vehicles** https://www.democratandchronicle.com/story/news/2021/04/08/naples-ny-teen-designs-builds-underwater-vehicles-boy-scout-troop/7091760002/  (30:57) **Willard Bay State Park adds a new day use pond** https://cachevalleydaily.com/news/archive/2021/04/05/willard-bay-state-park-adds-a-new-day-use-pond/  (33:00) **Researchers Recover More Artifacts from the Ship that Carried the Elgin Marbles** https://www.warhistoryonline.com/news/elgin-marbles.html  (38:11) **Apple wins Patent for a distinct Underwater Mode GUI for a Future iPhone** https://www.patentlyapple.com/patently-apple/2021/04/apple-wins-patent-for-a-distinct-underwater-mode-gui-for-a-future-iphone.html  (41:53) **Nuclear-powered super-yacht costs $3m a ticket but climate change students will ride for free** https://www.indy100.com/news/climate-change-students-nuclear-powered-superyacht-b1831529  (50:40) **End of scuba in the news** (50:41) **Gilboa Quarry with new Ownership** (1:00:09) **Wrapping Up** (1:04:01) **Bad Joke of the Week** Format Change is less than a month away - Youtube https://www.youtube.com/channel/UC-7NUj7Q4ihcqpp1yODCFzw Intro & Outro Music Music “Tornado” by Wintergatan This track can be downloaded for free at www.wintergatan.net Free License to use this track in your video can be downloaded at www.wintergatan.net
