A new study reveals that bioacoustics is an underutilized wildlife study tool on one of the world's most biodiverse continents: Africa.

On this episode we discuss this gap by highlighting two new bioacoustics studies of hippos and African manatees - and we of course play recordings of their squeals, squeaks and 'wheeze honks' which can now aid their conservation.

Dr. Nicolas Mathevon joins the show to share the results of a study which showed that vocal recognition is used by hippos, and we welcome Clinton Factheu, a PhD student in Cameroon who recently co-authored a study revealing the first recorded African manatee vocalizations.

Mongabay Explores is an episodic podcast series that highlights unique places and species from around the globe. Subscribe to the show wherever you get podcasts and stay tuned for subsequent episodes in this season. New Guinea is home to the third-largest tropical rainforest in the world—of which 80% is still intact. The two-nation island also contains 44 species of unique birds-of-paradise and dense biodiverse regions unlike anywhere else on the planet. Because of its one-of-a-kind biodiversity, and relatively undeveloped landscape, New Guinea is in a unique position to conserve its forest cover as part of an economy that serves its local inhabitants, rather than extracting from and deforesting these communities.

For this third episode of the New Guinea season, Mongabay interviews Bustar Maitar, CEO of EcoNusa, and biologist Edwin Scholes from the Cornell Lab of Ornithology about the diverse and charismatic birds-of-paradise and the potential for New Guinea to harness ecotourism to power a sustainable economy.

Join us for a dive into two ambitious Indigenous-led conservation initiatives on the U.S. West Coast on this episode. 

Host Mike G. speaks with Dune Lankard, founder and president of The Native Conservancy, who discusses their work to create a regenerative economy for Alaska’s Prince William Sound--based on conservation and restoration-- via projects like kelp farming.

We also speak with Tiana Williams-Claussen, she's the director of the Yurok Tribe’s Wildlife Department and shares their efforts to bring condors back to the tribe’s territory in Northern California, which is set to culminate in the first four birds being released into the wild in April 2022.

Articles mentioned:

• “Thanks to the Yurok Tribe, condors will return to the Pacific Northwest” 
• “By cultivating seaweed, Indigenous communities restore connection to the ocean”
• Mongabay Series: Indigenous Peoples and Conservation

Since 2014, Papua New Guinea has been the world’s largest tropical timber exporter: more than 70% of that is considered illegal. Timber companies continue to possess land originally owned by local Indigenous communities through legal loopholes: while the carbon market has gained popularity as an alternative source of revenue for Indigenous communities, it suffers from some of the same land rights abuses as timber extraction. For this episode of Mongabay Explores we interview Gary Juffa, governor of Oro province in Papua New Guinea, and investigative journalist, Rachel Donald.
