What do we really know about biodiversity? Inside Biodiversity brings you in-depth conversations with leading researchers tackling the most pressing and controversial questions in biodiversity science. Each episode features experts who challenge common narratives, reveal surprising trends, and explore solutions for conservation.
From species extinctions to ecosystem resilience, we go beyond the headlines to uncover the complexities of nature. Whether you're a scientist, conservationist, or just curious about the state of life on Earth, this podcast will change the way you see biodiversity.
Inside Biodiversity is hosted by the German Centre for Integrative Biodiversity Research (iDiv)
In this episode, plant ecologists Ute Jandt and Helge Bruelheide explain why a greener planet isn’t necessarily a more diverse one. They discuss global greening, the rise of generalist species, the homogenisation of ecosystems, and how rewilding, forestry, and agriculture can help conserve plant biodiversity in a changing world with podcast host Volker Hahn.
In this episode, Volker Hahn talks to Carlo Rondinini, Professor of Zoology at Sapienza University of Rome, about wolves, beavers, otters, hedgehogs, jackals, and the global fate of mammals. They explore why some species are making remarkable comebacks in Europe, while one quarter of mammals worldwide are at risk of extinction. And although the threats are complex — from habitat loss and overexploitation to climate change — Rondinini says one solution matters more than almost anything else.
Why are insects declining — and what can social media teach us about biodiversity? Entomologist Dr Shawan Chowdhury talks with host Volker Hahn about his research on insect conservation and protected areas, the striking lack of data from tropical regions, and how Facebook, iNaturalist and other platforms can help fill these gaps. Shawan also shares how he uses social media not only as a scientific tool, but as a bridge between research and the public — and why communicating science across cultures matters as much as doing it.
Are insect numbers really declining — and if so, why? In this episode, entomologist Roel van Klink explains what long-term data reveal about global and local insect trends and why the causes behind these changes remain surprisingly uncertain. We also discuss why it is difficult to distinguish between natural fluctuations and human-driven impacts, such as land-use change or climate change. We explore what scientists currently know, what they still don’t know, and why understanding these drivers is crucial for biodiversity conservation.
