Today on the BioAudio podcast Prof Alex Mills returns to talk about how we recognize and describe an "ecological community" and the unique roll of keystone species, ecosystem engineers and apex predators. We will also talk about three famous trophic cascades, where the removal or introduction of a species has consequences that rebound across the entire system. 

Trophic Cascades 8-13-23 by LifePath Church

In this captivating episode of The Biome Podcast, we traverse the expansive plains of Africa and the dense forests of India, following the majestic footprints of the lion. Delve deep into the life history of this iconic predator, from the tender moments of playful cubs to the challenges of establishing dominance in the fierce world of the savannah. But there's more than just the lion's tale to tell. In our technical corner, we dive into the intricate dance of the food web, exploring the profound impacts of the lion's roar on its ecosystem. Join us as we unravel the concept of trophic cascades, showcasing how the presence (or absence) of a single apex predator like the lion can send ripples throughout an entire ecosystem, influencing everything from herds of grazing herbivores to the very grass they feed upon. So, gear up for a roaring adventure that spans continents, dives into the intricacies of ecology, and celebrates the wonder of the natural world. It's a tale of majesty, science, and the interconnected tapestry of life on The Biome Podcast. --- Send in a voice message: https://podcasters.spotify.com/pod/show/biome-media/message

Level 3 CyberTracker certified tracker and author Janet Pesaturo joins us to discuss:-her background-her start in tracking -why she loves tracking and using game cams-what is involved in tracking and using game cams-her book Camera Trapping Guide: Tracks, Sign, and Behavior of Eastern Wildlife-Bobcat behavior and lifestyle -Fisher behavior and lifestyle-Bear tracking and making behavior -animal nature, animal consciousness, human philosophy of animal consciousness, the nature of science, and the history of science-what she has learned from tracking and using game camsAbout Janet: "A Massachusetts native, Janet admired the flora and fauna of her suburban surrounds from an early age. A seventh grade teacher inspired her interest in life sciences, which she has pursued in a variety of ways over the past several decades. She has a Medical Degree, and practiced psychiatry for about 10 years before leaving to raise her children full-time. In 2004, she launched Animal Trackers of New England (formerly Nashaway Trackers), a group of wildlife enthusiasts who tracked for fun, and occasionally provided data to local conservation organizations. Soon thereafter, she began using trail cameras to learn about wildlife behavior. In 2013, she completed a master’s degree in Conservation Biology, and in 2014 she earned a Level III CyberTracker certificate. Janet has led many tracking walks, and has given several presentations on tracking and camera trapping. In 2018, her first book, Camera Trapping Guide: Tracks, Sign, and Behavior of Eastern Wildlife, was published. She currently authors this blog, Winterberry Wildlife."Contact Michael:1. ccerppodcast@aol.com2. http://www.goldams.com 3. https://www.linkedin.com/in/michael-gold-2883921/ 4. https://www.facebook.com/groups/1152144714995033/Join us at CCERP on Facebook! https://www.facebook.com/groups/1152144714995033/Show notes1.

I had some other examples in mind, but did not speak them. Developing them was not relevant to the discussion, nor was discussing in more depth the logic of the situation. But "priming the pump"of memory and thought is something we all could do more. It is an important thinking skill. Note: philosophies of science based on the work of Plato, Kant, Descartes, Dewey, Kuhn, Popper are fundamentally wrong. Science is not essentially deductive. It is not "above and beyond" experience or anything like that. Science is the inductive, integrated understanding of that nature of things and their cause-effect relationships. It is founded on and developed out of the evidence of the senses.Picture and bio courtesy Janet Pesaturo.

In this episode of the Conservation Queens we discuss the concept of trophic cascades and look at some examples of this phenomenon involving animals like stingrays, sharks, sea urchins, wolves, and others. Beware of the bad puns that may come in this episode. They're otterly ridiculous! 

Renowned ecologist Jim Estes shares his story of discovery - from a young graduate student on the Aleutian Islands to scientific breakthroughs revealing the profound ecological effects of a keystone predator Produced in partnership with the Elakha Alliance Jim's memoir: https://www.amazon.com/Serendipity-Ecologists-Understand-Organisms-Environments/dp/0520285034/ref=sr_1_11?dchild=1&qid=1586768471&refinements=p_27%3AJames+Estes&s=books&sr=1-11 Trophic Cascades book coauthored by Jim: https://www.amazon.com/Trophic-Cascades-Predators-Changing-Dynamics/dp/1597264873/ref=sr_1_3?dchild=1&qid=1586768471&refinements=p_27%3AJames+Estes&s=books&sr=1-3

Dr. James A. Estes, PhD is a researcher, author, and professor of Ecology & Evolutionary Biology at the University of California, Santa Cruz. For the past 50 years, he has been studying the ecology of coastal marine communities and keystone species. He has authored nearly 200 scientific publications with a primary focus on sea otters and their impact on surrounding sea life. He currently oversees research projects in the Aleutian Islands, central California, the Channel Islands, and New Zealand.  In this interview, Dr. Estes describes the massive ecological shift that can be observed when reducing the numbers of a single critical species. He shares the moment he recognized the cascading effects resulting from diminished sea otter populations in the Aleutian Islands, which then spurred decades of research. He also discusses the effect humans have had on the balance of the Earth’s ecosystems with industries including the fur trade, whaling and agriculture.  Here’s the outline of this interview with James Estes: [00:00:25] Dr. Estes: background and interest in ecology.

With returning guest cougar behaviorist and ecologist John Laundré, we examine how recolonization of cougars in the Eastern United States could happen and why reintroducing cougars would not only be a sound decision from a scientific and ecological perspective but would also have a positive effect on society by reducing the exploding deer and elk populations and the negative impacts that arise such as deer-car collisions and increased cases of Lyme disease. The science is clear that carnivores have stabilizing effects on ecosystems, but the social and political will is lacking as we have lived for so long without them. Sport and Hunter-led policies of management to increase game-species without apex predators, is nothing short of an ecological crime. Apex predators are essential to ecosystem health and sustainability of North America's wildlife and habitats and without them we face unparalleled trophic cascades with severe consequences.

Friday, September 1, 2017 – Audio Recording   The stated purpose of Iron Leadership is “To act like men” by: equipping men to be better leaders in their own personal lives, their homes, their work, their churches and city for the sake of God’s Glory. This phrase: “Act like men” is lifted from Paul’s letter to the Corinthians. This phrase comes at the close of the Apostle Paul’s long and difficult letter. It’s difficult because the people in the church... Read More Read More

A "trophic cascade" is the effect of one change that causes a ripple effect of change all around it. When we introduce Jesus to one part of our lives, his presence causes a trophic cascade in which every part of us is made new.

Predators like lions, wolves and dingoes are at the very top of the food web - so what are the consequences when they're taken from an ecosystem?

The High Lonesome Institute (HLI) is a non-profit entity, established by The High Lonesome Ranch, to lead and coordinate applied scientific research, ecological monitoring, and conservation at the Ranch. It functions within HLR’s landscape-scale laboratory as an applied and practical research center and conservation forum.
