ZSL #043 Back to the Wild: Assessing disease risks for species reintroduction

Making sure that the animals held in ZSL’s two conservation zoos, London and Whipsnade, are fed a diet that can help them thrive is crucial, both for keeping them healthy under managed care, and ensuring they are in the best possible shape for a return to the wild. Amanda Ferguson is ZSL’s Diet Management Officer and is responsible for creating tailored diets for all the animals across both ZSL Zoos, from snails to elephants! We learn how to feed an animal for which there are no guidelines, why enriched feeding methods are so important, and why you’ll rarely see a monkey at London Zoo with a banana.

Out of sight…but not out of mind? Coral reefs exist largely out of sight for the majority of the world’s population, so the vast array of ecosystem services they provide for local communities are often forgotten, leading conservation efforts to feel like an uphill battle. In this episode, we talk to the people trying to tackle this problem; from using the sounds that healthy and degraded coral reefs make to monitor their restoration, to bringing people closer to coral reefs using virtual reality.   Overview 00:13    Introduction to the topic from Harriet McAra 01:26    Ben Williams, PhD student at the Institute of Zoology and UCL, on coral reefs’ importance, coral soundscapes and the Mars Assisted Reef Restoration System 08:30    Introduction to the Datascape Realities Project 08:52    John Zhang and Lourenco Viveiros, co-founders of Datascape Realities, and Jason Lynch, UCL and Institute of Zoology 28:14    Outro and further information Resources If there’s a topic you’d like to hear on a future podcast, or if you’d like to share your thoughts, email the ZSL Wild Science Podcast at: [email protected] Check out our science and conservation work at: www.zsl.org/Science or www.zsl.org/conservation Ben Williams: https://www.zsl.org/about-zsl/our-people/ben-williams Mars Assisted Reef Restoration System: https://www.buildingcoral.com/ and https://www.buildingcoral.com/news/mars-data-scientists-turn-their-skills-to-coral-reef-restoration Datascape Realities: https://www.datascaperealities.com/ and @datascape_real   Get in touch  Email [email protected] with your questions, comments, and thoughts for future episodes!

Co-existence between communities living on the Korean Peninsula and carnivores such as leopards, tigers and black bears, has historically presented many challenges leading to population declines in these species. However, thanks to international treaties such as the Convention on International Trade in Endangered Species, as well as economic growth and conservation translocations, the tide is now turning on these declines in South Korea. In this episode, host Harriet McAra is joined by Joshua Elves-Powell to discuss how wildlife trade has impacted carnivores in East Asia, and the conservation measures being taken to protect these globally threatened species.   Overview 00:20 - Introduction to the topic from Harriet McAra, and introduction to the podcast guest 02:24 - Josh Elves-Powell, PhD student at the Institute of Zoology and UCL, introduction and interview 27:06 - Outro and further information   Resources If there’s a topic you’d like to hear on a future podcast, or if you’d like to share your thoughts, email the ZSL Wild Science Podcast at: [email protected] Check out our science and conservation work at: www.zsl.org/Science or www.zsl.org/conservation Joshua Elves-Powell: https://www.zsl.org/about-zsl/our-people/joshua-elves-powell The latest publication from Joshua Elves-Powell, reporting major declines in South Korean big cat trade: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0299783 Project Moon Bear: https://en.projectmoonbear.org/Mission Korean Tiger and Leopard Conservation Fund: https://blog.naver.com/savetiger Blogs written by Joshua Elves-Powell Asiatic black bear restoration in South Korea: https://theconversation.com/south-korea-is-bringing-back-bears-in-a-country-of-52-million-people-i-went-to-find-out-how-164301 Moves to end bear farming in South Korea: https://theconversation.com/south-korea-to-ban-bear-farming-but-what-to-do-about-hundreds-of-captive-animals-that-remain-197316   Get in touch  Email [email protected] with your questions, comments, and thoughts for future episodes!

It’s no secret that cities are generally perceived as spaces of little conservation relevance, yet local urban wildlife underpins a range of ecosystem services. In a time where rapid changes in the climate are causing more extreme natural events, wildlife is disappearing and we are becoming more and more disconnected from nature through urbanisation, could the recovery of urban ecosystems be a potential solution for a more resilient planet? In this episode, our host Ellie Darbey will discover how we can recover nature in our cities, with ZSL’s experts in rewilding, reconnecting habitats and river restoration. Does the answer lie in empowering local communities? Or is it in the plight of the hedgehog? And why must we enact the mysterious Schedule Three?   Guests Professor Nathalie Pettorelli, Institute of Zoology, ZSL Dr Chris Carbone, Senior Research Fellow, Institute of Zoology, ZSL Joe Pecorelli, Conservation Project Manager, Marine and Freshwater, Conservation & Policy, ZSL Overview 03:31 – Ellie Darbey introduces the first guest, Professor Nathalie Pettorelli to discuss how to rewild in urban environments 16:39 – Ellie is joined by Dr Chris Carbone to talk about the London Hogwatch Project, and their community engagement 26:59 – Species Spotlight: The European hedgehog! 28:12 – Ellie welcomes the final guest Joe Pecorelli to discuss river restoration in London, and the power of the waterways 37:19 – The guests give their answer for the one thing they’d like to change in policy or legislation to help recover urban nature.

Pathology is the science of diagnosing diseases by observing physical changes in animal cells and tissues, either in living, or more commonly dead animals. In this episode, our host Ellie Darbey will explore the unseen…or rather, unheard world of wildlife pathology with the help of ZSL’s experienced pathologists, veterinarians, and scientists. Through post mortems on black widow spiders, to giant stranded humpback whales, these four pathology professionals will show the value of this diagnostic work to the conservation and welfare of animals in zoos and in the wild. What are the practicalities of examining large animals like elephants and rhinos? How can pathology be used to solve wildlife crimes? And what do pathology and The Supreme Court have in common? Guests Dr Simon Spiro, Wildlife Health Services, Zoological Society of London Dr Becki Lawson, Institute of Zoology, Zoological Society of London Rob Deaville, Institute of Zoology, Zoological Society of London Dr Tammy Shadbolt, Institute of Zoology, Zoological Society of London Overview 01:22 – Ellie Darbey introduces the first guest, Dr Simon Spiro, to discuss what it’s like to be a veterinarian pathologist, and how pathology can be used for animal welfare and conservation 14:06 – Ellie is joined by Dr Becki Lawson to explore the Garden Wildlife Health Project and the detective work used to discover a snake fungal pathogen in Europe. 27:15 – Rob Deaville joins to explain what happened to “Hessy” the humpback whale, and how the Cetacean Strandings programme works. 40:10 – Ellie welcomes the final guest Dr Tammy Shadbolt to discuss the Disease Risk Analysis and Health Surveillance Project and how pathology can help solve wildlife crimes. 49:44 – The speakers give their advice for pursuing a career involving wildlife pathology from their varied backgrounds and perspectives.
