The Real Reason Male Lions Kill Cubs (w/ Caroline Reinwald, Science Communicator)

from Not a Biologist - A Wildlife Behaviour Podcast

Have you ever wondered why male lions sometimes kill cubs when they take over a pride? In this wildlife podcast you’ll get a breakdown of lion infanticide, from pride takeover and evolutionary reproductive strategy to the hard-wired nature of survival in the wild. Welcome to the very first episode of our brand-new format: "Not a Biologist"! 🤗 At Terra Mater Studios, we film ambitious wildlife documentaries. We witness incredible and sometimes shocking animal behavior. But let’s be honest: when watching these scenes, many of us think… "Wait… why does this happen?" In this new series, our host Alex (who is not a biologist) sits down with experts to ask exactly those questions; the ones you might be thinking at home. For Episode 1, we’re diving straight into one of the most difficult behaviors to watch in the wild: lion infanticide. After reacting to a powerful scene from our movie "The Bastard King", Alex speaks with zoologist and science communicator Msc. Caroline Reinwald (Zoo Vienna) to unpack what’s really happening.🍿 "The Bastard King" (full length movie): https://youtu.be/es_D0Dzl7YQ🎙 Guest: Caroline Reinwald, MSc Zoologist & Science Communicator (Vienna Zoo) https://www.zoovienna.at/en/ 💚 A big thank you to our expert Caroline Reinwald for sharing her knowledge and helping us navigate one of the most challenging topics in wildlife behavior.📚 Further Reading & Studies Mentioned: Lions roar: https://onlinelibrary.wiley.com/doi/10.1002/ece3.72474 Females mating with several males: https://academic.oup.com/beheco/article-abstract/30/4/1050/5435127 Mating with more than one male: https://onlinelibrary.wiley.com/doi/10.1111/mec.12279
