Noise Pollution Impacts on Birds w/Natalie Madden

Chris interviews Natalie Madden of Defenders of Wildlife on how noise pollution impacts birds. Drawing on a meta-analysis of 160 studies, she highlights strong negative effects on reproduction, along with changes in behavior, communication, and stress physiology. The episode explores major noise sources, links to broader bird declines, and practical ways at both individual and policy-level to reduce noise and support conservation.

Originally recorded in 2020, this episode dives into the fascinating world of the American black bear—one of North America’s most adaptable and misunderstood large mammals. From dense forests to suburban neighborhoods, black bears have quietly become one of the most successful large carnivores on the continent. But behind their familiar image lies a highly intelligent, resourceful animal with complex behaviors and a critical role in maintaining healthy ecosystems.

Chris reframes migration as a planet-connecting system that moves energy and nutrients and keeps ecosystems in sync—now facing a growing “migration collapse,” where patterns break down before species disappear. He explores three failure modes: disrupted timing from climate change, broken routes from human barriers, and energetic failure when animals can’t find enough food. Through monarch butterflies, gray whales, and salmon, he shows a spectrum from fragile resilience to systems already failing. The episode closes with a hopeful message: when pressure is reduced, nature can respond—and protecting migration corridors is key.

In this re-release, Chris and Angie highlight why Meerkats may be small, but their world is anything but simple. Native to the arid regions of southern Africa, these highly social mammals live in tight-knit groups where every individual has a role. From babysitters and hunters to vigilant sentinels standing guard against predators. Their cooperative behavior is one of the most sophisticated in the animal kingdom, offering a powerful glimpse into how survival can depend on communication, trust, and teamwork. While meerkats are not currently endangered, they face growing pressures from habitat degradation, climate variability, and human expansion across their range. In this episode, we revisit one of nature’s most charismatic species and explore what meerkats can teach us not just about life in the desert, but about resilience, community, and the power of working together. == Another thank you to all our Patreon supporters.

Chris draws on his PhD-era experience at Texas A&M—including meeting Dewey, the world’s first cloned deer—to unpack de-extinction and why cloning is far harder and less efficient than headlines suggest. He revisits Dolly’s breakthrough, explains somatic cell nuclear transfer, and highlights low success rates and frequent abnormalities. Chris explores the only true de-extinction attempt, the Pyrenean ibex, which survived only minutes, and explains why mammoths and “dire wolves” cannot be truly cloned due to fragmented DNA, with current efforts relying instead on genetic engineering. Chris also outlines major challenges around elephant egg sourcing, embryo transfer, and gestation, questions claims that mammoths could meaningfully impact climate change, and argues conservation resources are better directed toward protecting existing species, while acknowledging potential scientific benefits from the research.

Chris and Angie venture into the darkest depths of the ocean to meet one of the most bizarre and misunderstood creatures on Earth—the anglerfish. In this episode, we explore how these deep-sea predators survive in a world without light, using bioluminescent lures to hunt in the abyss. But it’s their reproduction that truly defies belief, featuring one of the most extreme mating strategies in the animal kingdom. We also unpack what anglerfish reveal about life in extreme environments and why the deep ocean, still largely unexplored, matters more than ever. =========================================================== Another thank you to all our Patreon supporters.

Chris welcomes Dr. Sammy Ramsey (“Dr. Bugs”), entomologist at the University of Colorado Boulder, to discuss Secrets of the Bees (National Geographic, Disney+/Hulu). They explore surprising bee intelligence—from navigation using the sun to puzzle-solving, teaching, and even play—alongside fascinating behaviours like the waggle dance and swarm decision-making. Ramsey debunks common myths about honeybees and explains why they’re less aggressive than wasps. The episode also tackles colony collapse, ongoing hive losses, and the impact of varroa mites. He shares simple, practical ways people can help protect pollinators at home.

Bringing back an older episode, but a classic! This week, great news as Monarch Butterfly winter populations have regained 60% of their population numbers vs previous years! Once again, conservation is proving to work and thus, we are releasing this older episode. Chris and Angie delve into their life cycle, migration patterns and unique 'super generation'. They also discuss the butterflies' ecological importance and the role they play in pollination and ecosystems. The hosts share their experiences of visiting a university's natural history museum and butterfly breeding program. With a focus on the alarming decline in the Monarch butterfly population, threats like climate change, pesticide use and habitat loss are highlighted. They also bring attention to active conservation organizations like Monarch Watch and the ESS Society, and promote involvement in citizen-science projects. They encourage listeners to contribute to butterfly conservation by planting pollinator gardens, with a forthcoming resource on suitable plants for different U.S regions.

This was our 50th episode we did back in 2018. How far we have come over the years. Sea dragons are among the most extraordinary fish on Earth, found only in the temperate coastal waters of southern Australia. Close relatives of seahorses, species like the leafy, weedy, and ruby sea dragon drift through kelp forests and seagrass meadows disguised as floating seaweed. Their intricate, leaf-like appendages aren’t used for swimming but for camouflage, allowing them to vanish into their surroundings. And like seahorses, it’s the males who carry the eggs, brooding them externally until they hatch. Although they look mythical, sea dragons are very real — and increasingly vulnerable. They rely on healthy kelp forests and stable coastal ecosystems, which are under pressure from warming oceans, marine heatwaves, pollution, and habitat degradation. Because they are poor swimmers and highly specialized to their environments, they cannot easily relocate when conditions change. Protecting sea dragons means protecting entire underwater ecosystems that support rich marine biodiversity. =========================================================== Another thank you to all our Patreon supporters.

Chris reflects on the state of nature in 2026, where conservation is defined by both loss and recovery. While habitat fragmentation, climate warming, coral bleaching, and Arctic instability continue, meaningful protection efforts are delivering results. He highlights conservation wins, including pandas downlisted to vulnerable, green sea turtles to least concern, tiger recovery in India through reserves and anti-poaching, Gabon’s protection of forest elephants for rainforest integrity and carbon storage, and community-led snow leopard conservation in Nepal. The episode also addresses ongoing losses, key drivers of biodiversity decline, global efforts like 30x30 and the High Seas Treaty, and practical ways listeners can help — from reducing consumption to supporting frontline conservation initiatives like Snow Leopard Sisters. 00:00 Welcome and Reality Check 00:46 Conservation Is Tension 02:40 Climate and Biodiversity Link 03:17 Resilience and Hope in Action 04:40 2026 Roadmap for Today 05:42 Big Wins Pandas and Turtles 07:55 India’s Wildlife Comeback 11:00 Gabon Forest Elephants 14:45 Snow Leopard Sisters Spotlight 19:44 Losses and Extinctions 24:25 Why Extinction Is Accelerating 27:45 Five Biggest Threats 29:46 Mainstream Momentum and 30x30 35:48 People Giving Hope 38:21 What You Can Do Now 42:43 Support Snow Leopard Conservancy 44:38 Final Call to Action Learn more about your ad choices.
