In the beginning of the 20thcentury, the population had faced a sudden decline as a result now koalas have gone extinct in Tasmania or Western Australia. The origin of koalas is still in ambiguity however, some of the koala fossils have been discovered in northern Australia dating back to 20...
Paleontologist Larisa DeSantis studies the teeth of ancient and modern mammals to determine how their diets changed across the millennia and, by extension, their responses to climate change. But the question lingered: Is wear onteethan indicator of what kangaroos and koalas ate or just how much ...
the koalas’ diet consists almost completely of eucalyptus leaves. They will occasionally eat other leaves but prefer this type by far. The only problem with their eucalyptus-rich diet is that koala joeys can’t digest it.
And one advantage of being a specialist feeder with a basic diet, is that there are relatively few odour cues to learn. It's also fortunate the leaves koalas are checking out are right in front of their noses! The koala's nose might not only smell plant toxins, it may also play a mi...
1Koalas, an Australian tree-climbing animal, are very particular about what they eat, devoting themselves entirely to a diet of the leaves of eucalyptus trees. But there are problems associated with an exclusive diet of leaves, especially if, like the koala, you happen to be a relatively smal...

Unfortunately, bad information comes mixed with the good. The only reliable guide to reality is science, but when it comes to food, there's a problem. It's hard to do a gold standard double-blinded randomized controlled study on diet. We could learn a lot if we could divide infants ...
