Dr. Rae Wynn-Grant, large carnivore ecologist, shares insights on hibernation, carnivore microbiomes, and the intelligence of bears. She discusses stuffing baby bears in coats, the tasting abilities of carnivores, and the vegetarian carnivore concept. The podcast delves into the unique adaptations and behaviors of carnivores like wolves and how they interact with humans.
Carnivores can have diverse diets, from obligate meat-eaters to omnivorous species like bears.
Large carnivores play a crucial role in ecosystem balance and their conservation is vital.

Carnivore Ecology and Classification
Carnivores are meat-eating animals, but not all carnivores eat meat. The term 'carnivore' is derived from a taxonomic order called 'carnivora', which includes over 280 different species of mammals. This order is defined by animals with sharp teeth, long claws, and the ability to process meat in their digestive systems. However, some omnivorous carnivores like pandas primarily eat bamboo, but still possess the characteristics of a carnivore. The taxonomy classifies them as carnivores based on their biological characteristics and evolutionary history.
Carnivore Diet and Behavior
Carnivores exhibit a range of dietary preferences and behaviors. Obligate carnivores, such as lions and tigers, rely on fresh prey and consume raw meat. They do not typically eat vegetation or other non-animal food. On the other hand, omnivorous carnivores, like various bear species, wolves, coyotes, and raccoons, have a wider dietary breadth. They can consume both meat and plant-based foods, including fruits, grasses, and even honey. Their food choices are driven by a need to accumulate fat, and they have the ability to survive in diverse landscapes due to their broader dietary options.
The Role of Large Carnivores in Ecosystems
Large carnivores, such as bears and lions, play a crucial ecological role. They are considered ecosystem engineers and help maintain balanced ecosystems. By being at the top of the food chain, their presence influences the population dynamics of other species and maintains the health and diversity of landscapes. The conservation of large carnivores is vital not only for their intrinsic value but also for promoting healthy and vibrant ecosystems. Understanding their behavior, dietary habits, and ecological role is necessary for effective conservation and wildlife management strategies.
Ah, charismatic megafauna! Teeth, claws, fur, poop, hibernation, hiking, nature preserves, and living your childhood dreams with Alie’s longtime -ologist crush, Dr. Rae Wynn-Grant. The large carnivore ecologist, researcher and TV presenter tells us all about her field work, what it’s like to stuff a baby bear in your coat, carnivore microbiomes, how well carnivores can taste and smell their food (and yours), how smart the average bear really is and more. Also: Is there such thing as a vegetarian carnivore?! We love her.
