ZSL #051 From Habitat to Husbandry: Evidence-based animal care

Modern zoos play a critical role in global conservation, but supporting wildlife under human care goes far beyond habitat design. Hear how ZSL's experts use science, behavioural insight and veterinary care to help animals thrive and support species on the brink of extinction. From ensuring penguins can express their natural behaviours, to delivering tailored veterinary care to supports lions' long-term health and welfare, this episode of Wild Science shines a light on the dedication and expertise within ZSL's Evidence-based Animal Care Team and beyond.

ZSL #050 Mapping Nature's Code

How does our DNA, the tiny building blocks that make every species, and every individual, totally distinct, impact our evolution? In this episode, we learn how we can visualise our DNA, or genome, to allow us to better organise the tree of life, and how learning more about this genetic make-up can provide insights into how a species survives in the face of a changing environment. We head to Cambridge, to ring native UK birds and collect samples of their DNA, and then to the Wellcome Sanger Institute, to see learn how those samples are processed and sequenced as part of a collaborative project aiming to sequence the genomes of all eukaryotes in Britain and Ireland; the Darwin Tree of Life project. Overview 00:11 Harriet McAra, Host of Wild Science, Episode introduction 01:26 Bird ringing in Cambridgeshire and Dr Ava Jenkins, Wildlife Veterinarian and Postdoctoral Research Associate, ZSL Institute of Zoology 03:13 Professor Mark Blaxter, Head of the Tree of Life Programme, Wellcome Sanger Institute 06:18 Dr Tom Mathers, Senior Computer Biologist, Wellcome Sanger Institute 12:44 A word of thanks 18:44 A final thought from Mark Blaxter 22:57 Outro Hi-C contact map of the common crane (Grus grus) Hi-C contact map showing the common crane genome (https://wellcomeopenresearch.org/articles/10-119/v1) after manual curation.

ZSL #049 The forest behind your floorboards

Do you know where the wood in your floorboards comes from? Or your desk, or dining chairs? In this episode, we dig deep into the grain of a global issue that is often hidden in plain sight in our offices, our houses and our cities – tracing timber back to its source. Harriet talks to Annabelle Dodson, ZSL's Sustainable Business Project Manager, and Victor Deklerck, Director of Science at World Forest ID, about how scientists use isotopes to pinpoint where the trees behind our wood products were grown, the role of digital tracking systems in supply chains, and real-world cases where traceability has driven more responsible sourcing and enforcement. This project is funded by Fondation Lombard Odier and the EU through the ECO-SOLVE project. This episode is part of a series showcasing ZSL's Sustainable Business and Finance work. Please note that this podcast was recorded before the European Commission confirmed changes to the implementation timeline of the EU Deforestation Regulation (EUDR). Compliance requirements for micro and small enterprises have been delayed to 30 December 2026 (previously June 2026), while medium and large enterprises must still comply by 30 December 2025.

ZSL #048 The rubber story and the road to sustainability

What do car tyres, yoga mats and trainers have in common? They all contain natural rubber, tapped from trees by millions of small farmers, mostly in Asia. While natural rubber production is renewable, its impact on the environment through deforestation, habitat loss and soil degradation, can be great when not managed sustainably. In this episode, we hear from a Thai rubber farmer, about the challenges faced on the ground, as well as one of the world's biggest tyre makers, Michelin, about rubber's colonial history, its tangled supply chains, and how they're working with farmers on sustainability. Finally, we explore how investors can use their influence to demand better practices and drive industry-wide change that benefits both people and nature. This episode is part of a series showcasing ZSL's Sustainable Business and Finance work.

ZSL #047 Shark Tales of North Wales

The coastal waters of Wales are home to a whopping 27 species of sharks, skates and rays, known collectively as elasmobranchs, and they are a fundamental part of Wales' natural heritage. But even so, research on their biology and conservation status is lacking. In this episode, Wild Science hits the road to join scientists from Project SIARC and the Ocean Predator Lab in North Wales as they work with local fishing communities to monitor tope sharks, and contribute to better understanding and conservation of shark species in the region.
