Dr. Edward DeLong is a Professor in the Department of Oceanography at the University of Hawai'i Mānoa as well as a Visiting Professor in the Department of Civil and Environmental Engineering at MIT. Research in Ed's lab brings together a variety of disciplines to study microbial communities in the ocean. He is interested in their ecology, evolution, biochemistry, genomics, and their impacts on marine systems. Particularly of interest for Ed are the microscopic organisms that are the primary producers or “forests of the ocean” responsible for releasing oxygen and serving as food for other organisms in marine food chains. When he's not working, Ed loves to be out in nature. He enjoys spending time outside with his family, hiking, kayaking, and snorkeling in the beautiful coral reefs near his house. Ed has also taken up yoga to help him stay limber and relaxed. Ed received his B.S. in Bacteriology from the University of California, Davis and his Ph.D. in Marine Biology from the Scripps Institute of Oceanography. Afterwards, he conducted postdoctoral research at Indiana University. Ed has worked as a research scientist at the Woods Hole Oceanographic Institute, a faculty member at the University of California, Santa Barbara, a research scientist at the Monterey Bay Aquarium Research Institute, and a faculty member at MIT before accepting his current position in Hawai'i. His honors and achievements include the Office of Naval Research Young Investigator Award, the DuPont Young Faculty Award, the Apple Bioinformatics Cluster Award, the Vladimir Ivanovich Vernadsky Medal of the European Geosciences Union, the Proctor and Gamble Award in Applied and Environmental Microbiology, American Society for Microbiology D.C.

Reintroducing Hawaii's sacred crow to the wildThe world's most endangered crow, the Hawaiian crow or or ʻalalā, is making tentative steps towards a comeback. After going extinct in the wild, only 120 birds remain in captivity, in two facilities operated by the San Diego Zoo. Over the years, researchers have attempted reintroductions in the bird's native habitat on the Big Island of Hawaii, but those efforts have all been unsuccessful. Recently, the team tried something different - reintroducing the birds to a different island than their native home. The initial release happened in October and so far, the team, including Bryce Masuda, has high hopes and positive signs from their latest attempt.Lasers tell us about the pterosaur's unique tailThe great flying reptiles of the dawn of the age of dinosaurs, the pterosaurs, took flight with delicate but flexible internal tail structure that allowed it to work like a kite. Scientists used recently developed technology to enable them to see a lattice-like structure in the soft tissue in the early pterosaur soft tissue that was otherwise invisible to the naked eye. Natalia Jagielska, a paleontologist at the Lyme Regis Museum in Dorset, England, said their kite-like tail vane would have stood upright and could have functioned as a display and to help them in flight. The study was published in the eLife journal, Evolutionary Biology. How gophers help re-seed volcanic landscape with lifeAfter Mt. St. Helens exploded in 1980 it left a shattered, ash-covered, barren landscape behind. But the one-time reintroduction of gophers to one area led to a remarkably fast recovery of plants and other fauna. Forty-years later, changes to the environment are still being documented by Dr. Mia Maltz, assistant professor of Microbial Ecology and Soil Earth at the University of Connecticut, and her team. They published their research in the journal Frontiers in Microbiomes.Desert ants' magnetic navigationDesert ants that navigate the endless sands of the Sahara use the Earth's magnetic field to find their way, which is not unusual. But unlike other animals like birds and turtles they don't appear to have an internal compass that aligns north and south. Instead they are unique in that they use a more subtle cue – the polarity of the magnetic field. A study looking at this led by Dr. Pauline Fleischmann, a post-doctoral researcher at the University of Oldenburg in Germany was published in the journal Current Biology. Celestial body mysteries: dark comets and meteorites from young asteroid families The thousands of small celestial bodies in our solar system are now a bit less mysterious, thanks to several recent discoveries. One group of astronomers have traced back the origins of 84 per cent of all known meteorites that have pummeled Earth to just a few young asteroid families in the asteroid belt. Michaël Marsset, from the European Southern Observatory in Chile, said collisions in the asteroid belt create a collisional cascade that produces fragments, some of which end up raining down on Earth as meteorites. Two of their papers were published in the journal Nature and a third in Astronomy & Astrophysics. Another group of astronomers have identified two populations of stealthy dark comets that are something in between a comet and an asteroid. They've found fourteen of these objects whose orbital motion is comet-like, but which lack a visible tail like regular comets. Davide Farnocchia, a navigation engineer at NASA's Jet Propulsion Lab, said they've found two types of these unusual solar system bodies: larger ones in an elliptical orbit out to Jupiter and smaller ones in orbit around Earth. Their study was published in the journal PNAS.

The power of observation and a receptive mind are critical to farming, soil health, research, and all discoveries. Jeff Ishee, Mary Sketch Bryant, and Eric Bendfeldt start the New Year and third season of the 4 The Soil podcast with another conversation with Dr. Stuart Grandy, Professor of Natural Resources and the Environment, at the University of New Hampshire (UNH). It turns out the most powerful tool farmers and gardeners have regardless of size is taking time to observe and reflect on what is happening and observing how soil and plants respond to different management strategies. This tool can be used while sitting in a lawn chair or on a tractor. Therefore, the power of observation, good on-farm research, and a receptive mind should never be undervalued in building soil health and discovering the multiple functions and resilience soil can provide particularly during times of drought. To learn more about Dr. Grandy's research at the UNH Center of Soil Biogeochemistry and Microbial Ecology, please visit https://colsa.unh.edu/soil-biome.

How does one measure and monitor what's happening below the ground in the soil food web? Jeff Ishee, Mary Sketch Bryant, and Eric Bendfeldt caught up with Dr. Stuart Grandy, Professor of Natural Resources and the Environment, at the University of New Hampshire (UNH) to discuss the diversity of soil life and emerging sensor technologies to probe soil organic matter, soil carbon, and overall health. Dr. Grandy outlines why core soil health principles are essential for encouraging fungal hyphae, increasing the diversity of habitats, and enhancing food substrates needed to build a robust soil food web. He emphasizes how important the power of observation is and how he is constantly inspired by farmers' observations and their ongoing on-farm research for increasing productivity and reducing environmental impacts.

Today on Mushroom Hour we are joined by the incredible myco-maven Mia Maltz PhD. As a UC President’s Postdoctoral Fellow in the Division of Biomedical Sciences at UC Riverside, her research focuses on fungal communities and functional ecology in novel ecosystems, including pumice plains, drying lakebeds, and the lung mycobiome. Mia studied at the University of California, Irvine where she received my Ph.D. in Ecology and Evolutionary Biology, with an emphasis on Ecological Restoration and Fungi. Her dissertation work in Kathleen Treseder’s Lab of Fungi, Ecosystems, and Global Change looked at the effects of habitat fragmentation and ecosystem degradation on fungal community composition and function. For her dissertation research, Mia investigated whether restoration techniques affect fungi and evaluated the efficacy of methods for restoring mycorrhizal fungal function within degraded landscapes. As an ecologist working at the interface of community ecology, biogeography, and mycology, her work broadly focuses on community responses to environmental perturbations, which feedback to influence plant and fungal community structure and ecosystem functioning.

"Why are some fungi helpful and others harmful?" asks Paul Glaister in Reading. Rutherford and Fry try to outdo each other with fungal top trumps to get to grips with the answer. Decomposition ecologist Lynne Boddy, Professor of Microbial Ecology at Cardiff University, helps Hannah calculate the amount of dead plant material we’d be buried in across the globe, if we didn’t have fungi to recycle it. And she describes her first fungal encounter in her student flat which was riddled with dry rot, and explains how without fungi, we wouldn’t have plants. On Adam’s team is Curator of Mycology, Dr. Bryn Dentiger, at the Natural History Museum of Utah. Bryn tells Adam that he can’t think of a single food that doesn’t have some association with fungus. And the links are mostly positive rather than just mould on the top of your jam or rotten fruit in your fridge. He introduces Adam to the Humungous Fungus – the biggest living organism on Earth - and they get excited at the prospect of 20,000 different fungal sexes. The pros and cons of fungi don’t stop there. Microbiologist Dr. Ada Hagan,in Michigan lists some of the fungal diseases we’re prone to, and the numerous drugs derived from fungi that help treat a whole host of common diseases.

Today on Mushroom Hour we are joined by the distinguished Lynne Boddy, Professor of Microbial Ecology at Cardiff University. After undergraduate studies in Biology and Mathematical Statistics at the University of Exeter, she was interested in any and every type of ecology. A fortuitous position at the University of London led her to studying wood decay processes, which would turn out to be the subject of her PhD. That work snowballed into a 40-year exploration of wood decay processes with fungi at its core. As well as scientifically challenging and environmentally of massive consequences, mycelia and their interactions have a huge aesthetic appeal for Professor Boddy. There are so many burning questions when it comes to fungal biology, fungi’s relationships to food sources, fungi’s relationship to other fungi and other microorganisms that she, along with around 40 PhD students, post-docs and other co-workers, have striven and are striving to answer. Lynne’s passion for fungi laces out into studies of mycorrhizal fungi, the rising amateur mycologist community, and nearly every other aspect of how fungi will change human lives. There is an obvious joy in her communication of this information to both student audiences and to the public at large. We’re about to enter an exciting world of fungal battles, life and death struggles, epic hunts for food and the complexities of non-human intelligence.

Professor Wood specializes in the roles of soil microbial communities and is currently studying the importance of microbial diversity impacting plant diversity in rainforests. In this podcast, she explores How microbial communities in soil may work to reduce plant species that are too dominate, Why studying the importance of microbes in the environment involves following them by trait rather than by taxonomy, and How a better understanding of the ecology of microbial communities in the rainforest may lend itself to following rainforest response to fire damage. Dr. Jen Wood is an associate lecturer in the Department of Physiology, Anatomy, and Microbiology at La Trobe University in Australia. She's just begun co-heading a laboratory that centers on understanding the role of microbes in ecosystems so that scientists might better manage these systems, whether in an agricultural, rainforest, or human-gut setting. She describes a particular study near Queensland examining why rainforests are so botanically diverse. They've observed that something happens when the plants move from the seedling to sapling stage that manages and sets up this effective balance. The evidence points to microbes killing off dominate species, maintaining a degree of balance. She discusses many findings, challenges, and procedures that spin from this study. For example, when they try and compare soil patches, the microbial turnover is too great and the rhizosphere is so interconnected that separating out by species is too complicated. Therefore, rather than compare three seedling patches taxonomically, they compare them by microbial traits. A trait is any physical or morphological attribute that helps an organism compete. Examples include motility, presence of efflux pumps, ability to produce antibiotics, and ability to undergo chemotaxis. She notes that when comparing three patches by microbial traits, they've found patterns in the data. She also addresses fire in rainforests and studying recovery and ways to understand competition in these environments.

My guest is Sandra Phoma, she's from Mafikeng and studying in Pretoria, South Africa. In this episode, we learn that growing up Sandra had many interests ranging from arts, sports, and academic activities. After taking a gap year, she decided to focus on science and after fell in love with it. She tells us that she ventured into the field of ocean science with the skills she learned from her honors and a Masters's degree in microbiology. Currently, Sandra is a PhD candidate in ocean microbial ecology. Her work involves understanding the diversity, biogeography and functionality of the ocean microbiome. The sampling area includes waters south of Africa (South Indian Ocean and the Southern Ocean). She tells us about this research and the importance. During the PhD Sandra has had the opportunity to mentor, teach, and help lead other young scientists which she enjoyed. The European Union has also recognized Sandra as the South African ambassador for the All-Atlantic Ocean Youth youth program that helps connect local communities back to the ocean. Sandra mentions that despite the many successes in her academic journey, it can be a lonely one, primarily as a first-generation postgraduate student.

Kenneth & Blaire Mossman Professor of Microbiology, Steven W. Wilhelm, joins the show to talk about cyanobacteria, the problems presented by blue-green algae blooms, and the research he's conducting in the lab. In this episode, you'll learn: What the difference is between a blue-green algal bloom and a “dead zone” Why the switch from ammonium nitrate to urea as fertilizer about 25 years ago coincided with blue-green algal bloom issues In what ways toxic algal blooms are detrimental to humans and other species Cyanobacteria is responsible for carrying out more than 25% of the photosynthesis on the planet, which means that about one out of every four breaths of oxygen you take is thanks to these single-celled bacteria that can be found in abundance in every aquatic system in the world. But what happens when there's too much growth of cyanobacteria, and what causes overgrowth? Wilhelm explains that concerning algal blooms are driven primarily by human activity—specifically those activities which result in high levels of nutrients such as nitrogen and phosphorus being pumped into the environment and contributing to rapid population increases in cyanobacteria. When this happens, the algal blooms that form fundamentally change the water systems they are in by pushing out algae that may be better fish food, and producing toxins called microcystin and other compounds which can be harmful to other species, including humans. When these blooms die, they become food for heterotrophic bacteria that consume oxygen. As a result of this, “dead zones” form, which have significant impacts on fish habitat and other forms of aquatic life. So, what can be done about this problem? Wilhelm and the team at his lab spend a lot of time sequencing RNA and DNA in order to investigate why different organisms emerge under different circumstances. The hope is that with a better understanding of why cyanotoxins do so well under certain conditions (as opposed to more beneficial algae), it will be possible to intervene with a treatment or other method and prevent or limit further growth.

How can the intricate relationship between soil microbiota and plants be managed for improved plant health? Linda Kinkel discusses new insights into the plant rhizosphere and the ways that some Streptomyces isolates can protect agricultural crops against bacterial, fungal, oomycete, and nematode infections. Julie’s Biggest Takeaways: The soil microbiome is extremely dynamic, with boom-and-bust cycles driven by nutrient fluxes, microbial interactions, plant-driven microbial interactions, and signaling interactions. Finding the source of these boom-and-bust cycles can help people to manage the microbiome communities and produce plant-beneficial communities for agricultural purposes. Rhizosphere soil is soil closely associated with the root and is distinct from rhizoplane soil that directly touches the root. The endophytic rhizosphere are those microbes that get inside the root. Many scientists view these communities as a continuum rather than sharply delineated. Plants provide necessary carbon for the largely heterotrophic soil microbiota, and these microorganisms help the plants in several ways too: Microbes mediate plant growth by production of plant growth hormones. Microbes provide nutrients through mechanisms like nitrogen fixation or phosphorus solubilization. Microbes protect the plant from stress or drought conditions. Through a University of Minnesota plant pathology program, potatos were passaged in a field for over 2 decades to study potato diseases. Over time, researchers found fewer diseases in test crops, which led the plot to be abandoned in the late 1970s. In the 1980s, Dr. Neil Anderson planted potatoes to see if they would develop disease, but neither Verticillium wilt nor potato scab developed among the plants. Soil from the field (and on the potatoes) contained Streptomyces isolates that showed antimicrobial activity against bacteria, fungi, nematodes, and oomycetes. This discovery led Neil, new University of Minnesota professor Linda, and their collaborators to study the antimicrobial activity of natural Streptomyces isolates from around the world. Inoculation quickly adds specific microbial lineages to soil microbiome communities. Alternatively, land can be managed by providing nutrients to encourage the growth of specific species, like Streptomyces, within a given plot, but this takes longer to develop. How are soil microbiomes inoculated? Microbes can be: Added to the seed coating before planting. Placed in the furrow when the seed is planted. Distributed into the irrigation system.

Also available on the ASM Podcast Network app. Julie’s Biggest Takeaways The cheese microbiome makes a great study system because The communities are relatively simple (as few as 3 different microbial species) The microbial members are almost all culturable (in stark contrast to most microbial communities) The microbes colonize the cheese rind as a biofilm, which consists of the microbes and their secreted extracellular products. Like all biofilm communities, architecture and spatial structure are important for microbial interactions on cheese rinds, as are oxygen gradations, food access, and proximity to microbial neighbors. Rachel and her lab performed DNA sequencing on over 150 cheese samples from 10 countries to identify the microbes present on these rinds. By comparing these sequences to those they could grow in the lab (Rachel’s lab makes “in vitro” cheese medium consisting of desiccated, autoclaved cheese), they realized almost all of the organisms identified by molecular means were present in their cultures. Does the cheese environment influence the microbial communities or do the microbial communities influence the cheese environment? Both! The pH, temperature, added salt and temperature act as knobs or dials that allow cheese makers to fine tune the final cheese product. Rachel was inspired to work on cheese after taking the Microbial Ecology course at Woods Hole, where the students spent a lot of time looking at the beautiful but complex interactions within microbial mats. Upon cutting open some Tomme de Savoie from a French colleague, she noted similarities between the microbial mat and the layered cheese rind Featured Quotes “The biofilm that colonizes the surface of the cheese has a lot to do with how the cheese ends up looking and smelling and tasting, and we actually eat this biofilm when we eat the cheese.” “We’re able to see that of all of the things that we identified by reasonable sequence abundance, we could also find them in culture. This told us that we were able to get a lot of these microbes in culture, which is not really possible in microbial ecosystems, but is one of the really strong advantages of working in the fermented food community.” “We’re looking at these interactions because they’re happening on cheese and we can study them in the lab but they are things that are happening broadly across ecosystems, which I think is very exciting.” “We’ve done some work on the succession of species over time. You have these very very reproducible successions over time, even though a lot of these cheeses are not inoculated with specific species; these are species that are coming in from the environment but they’re very reproducible communities. There are some beautiful dynamics that happen and we’re starting to look at the interactions between species that may be driving some of these dynamics.” “We have this big need for model systems. One of the things I hope is that we’ll have more people developing simple model systems for microbial ecology so we can compare results and see what the general principles are.” Links for This Episode MTM Listener Survey, only takes 3 minutes!

Patrick Venail is a 39 year-old, French-Colombian community ecologist. He got his master’s degree in Biodiversity, Evolution and Environment at the Université de Montpellier II (France) on 2006 and his PhD on Ecology and Evolution from the same institution in 2010. In 2011 the French Society of Ecology awarded him as the best young ecology researcher after his publication in Nature about testing the influence of dispersal on the diversity and functioning of experimental metacommunities. From 2010 to 2013 he worked as post-doc fellow, first at the Universidad de los Andes in Bogotá (Colombia) and later at the School of Natural Resources and the Environment at the University of Michigan (USA) where he started using phytoplankton as an experimental model system. Since April 2013 he is a Senior Research and Teaching Assistant at the University of Geneva (Switzerland) in the Microbial Ecology group. His research focuses on understanding biodiversity (that is, the diversity of life). His interests are at the interface between microbiology, ecology and evolution. Working with microorganisms (e.g., bacteria, microscopic algae) allows him to explore both ecological and evolutionary processes simultaneously. He has mostly worked under controlled laboratory conditions but has recently been involved in several fieldwork studies in Russia and Ecuador. Currently he is focused in lake systems and the benefits they provide to humans, and into understanding the link between phytoplankton diversity and water quality. He has contributed to over 20 major scientific publications so far.
In this episode we explore the research that's going on pertaining to the microbiome as we talk with Jack Gilbert. He is one of the leading scientists in the area of microbial ecology. If you have done any reading about the microbiome online, you've probably come across his name.Jack has been involved in many research projects, and has published studies which relate to many areas of microbial ecology. He shares with us a bit of his story and we cover a lot of ground relating to all things microbial, but the theme that stood out to me is how we are all connected, how we need to steward our environment wherever we are, and how we need to use our brains to critically evaluate the information presented to us.Jack does a great job communicating these concepts and ideas, and I really enjoyed chatting to him.If you also get some value out of this show we'd appreciate if you'd take two minuets to give us a rating and review. This is a simple way of supporting us to keep doing what we're doing what we're doing.If your business wants to partner with the Probiotic Life, we're still looking for some strategic sponsorships. We're also doing some more collaborations to get things moving, so if you'd like to collaborate, reach out and connect!Here are some ways to find out more about Dr. Jack Gilbert:Lab WebsiteGoogle ScholarTwitterShow Notes- faculty director of The Microbiome Centre- professor at the Department of Surgery at the University of Chicago- senior scientist at the Marine Biological Laboratory- co-author of Dirt Is Good (with Rob Knight)- learned microbiology & physical chemistry in many different fields- spent time in Antartica studying bacterial proteins- got interested in understanding how microbes reacted & adapted to their environments in the world- this became his new passion- over the last ten years has become involved with human microbiome research- came to view the human body is simply another ecosystem seeking equilibrium, much like the sea/soil/plants, and we can treat it as suchWhat Aspect of Research is Jack Excited About Currently?- systems biology: viewing the world in a very connected way- how do microbes affect everything else in their environment?- capturing the complexity of these connections, so it can be predicted and adjustedGaps & Progress in Modern Research- concept of “one health”, the health of humans and all ecosystems are intrinsically linked- discussion of microbial environments in Amish and Hutterite communities- what are the associations between people and their disease, and other issues?- research is suggesting that consequences of severing ourselves from our environment could be much more severe than the risks of interacting with that environment- interact with your environment while still using common sense, e.g. wash your hands after petting animals- some authorities say they must give blanket statements regarding possible exposure to pathogens, in case of people not using common sense- you may be saving lives by doing this, but what is the cost to people's quality of life and potential to develop lifelong health complications?- what product could be created to provide to people who don't have access to a natural environment, to help their immune systems develop?Making Changes- for specialised information to become actionable to people who don't know that field, it must be put in a form that people can understand- Jack goes out and talks to many groups of people, because for change to happen, popular opinion needs to be swayed- finding a balance between letting the public know scientists are working on solutions to help them, but discouraging them from taking the untested research into their own handsContext is Everything- in a public bathroom, hot soapy water for cleaning is fine, sterilising the floor does little to prevent someone catching infectious illness- however, where someone is immunocompromised or with open wounds, e.g. a hospital, sterilisation is more beneficial- gearing public statements of what the public should be doing are geared towards protecting the most vulnerable in our society; unfortunately, this could potentially have negative impact on those who are not so vulnerable- listen to your doctor, be informed, and critically evaluate whatever you are toldCurrent Projects- boosting children's immune systems, immunology- ways to make plants more resilient to stress and disease- ways to negate use of fertilisers, pesticides, herbicides- all these contribute to the “one health” mandateClosing Thoughts- examining the role by which the world around us can be leveraged to impact health positively- being more engaged with the world around us, cultivating and interacting with a more biodiverse environment- Jack's book “Dirt Is Good” is a guide, with all the questions Jack's ever been asked about how the microbiome relates to our health; the decisions we can make with the information we currently have
Melvyn Bragg and guests discuss fungi. These organisms are not plants or animals but a kingdom of their own. Millions of species of fungi live on the Earth and they play a crucial role in ecosystems, enabling plants to obtain nutrients and causing material to decay. Without fungi, life as we know it simply would not exist. They are also a significant part of our daily life, making possible the production of bread, wine and certain antibiotics. Although fungi brought about the colonisation of the planet by plants about 450 million years ago, some species can kill humans and devastate trees.

In episode 61 of MicrobeWorld Video, filmed at the American Association for the Advancement of Science Meeting in Vancouver, Canada on February 17th, 2012, Dr. Stan Maloy talks with Richard Lenski Ph.D., Hannah Professor of Microbial Ecology, Michigan State University, about his research into the evolution of bacteria and the new frontier of digital evolution. Lenski's Long Term Evolution Experiment with E. coli has seen over 50,000 new generations since its inception in 1998. This has led to insights such as how viruses can evolve from types that don't infect humans to ones that do. Lenski's work with E. coli has also led him into the digital world. Using computers, Lenski can achieve precise, rapid results by manipulating digital organisms. Software that evolves much like bacteria in the real world. Lenski is optimistic about the future of evolution research. Applying the generalities that have resulted from his studies to any number of other microbial species. He also sees large potential in applying what he's learned to the study of antibiotic resistance and bioengery.
