On episode seven of the Newscast we talk with Mongabay contributing editor for Southeast Asia Isabel Esterman, who is based in Cairo, Egypt, about the plight of Asian rhinos. Potential new evidence recently emerged that suggests there might be some undiscovered wild Sumatran rhinos in Malaysia, where they were declared extinct in the wild last year — though not everyone is convinced the new evidence is all that compelling.

We also speak with Richard Bowden, a professor of environmental science at Allegheny College, to answer a question from a Mongabay reader and geography student at the University of Hamburg in Germany, who wrote in to ask: "What are the effects of climate change on phenology, primary production, carbon sequestration, and biotic interactions?"

If you've got a question about environmental science and conservation, we'd be happy to answer it for you! Just drop us a line at [email protected] and we'll answer your question in a future episode of the Mongabay Newscast.

We'd also like to thank the first ever sponsor: Lauten Audio, maker of professional studio microphones praised by everyone from Grammy-winning to novice producers, engineers, and musicians around the world. Thanks for your support Lauten Audio!
