By the 1990s the koala population had grown to the extent that they were consuming the leaves of their eucalypts at a rate beyond the trees' capacity to regenerate, and it was clear to scientists and others that some form of human intervention was necessary to avoid wholesale death of trees and distress to the koalas.
[11]: 96 Each day, koalas eat up to 400 grams (14 oz) of leaves, spread over four to six feeding periods. [2]: 187 Despite their adaptations to a low-energy lifestyle, they have meagre fat reserves. [2]: 189 Their low-energy diet limits their activity and they sleep 20 hours a day.
Herbivores which consume land plants may eat any or all of the fruit, leaves, sap, nectar, pollen, flowers, bark, cambium, underground storage organs like roots, tubers, and rhizomes, nuts, seeds, shoots, and other parts of plants; they frequently specialize in one or a few of these parts, though many herbivores also have quite diverse diets.

One of the world’s cutest tree marsupials may be in trouble. As it turns out Australia’s koala populations are declining fast.

Mature leaves contain a high proportion of hard-to-digest cellulose, less energy than other types of foods, and often toxic compounds. [1] For this reason, folivorous animals tend to have long digestive tracts and slow metabolisms.

Two koala bears having a disagreement is a pretty unexpected sight -- and the sounds they make will surprise you, too. It's sort of a mix between a ticked off bird and a clown on helium.
Nectar is produced by flowering plants to attract pollinators to visit the flowers and transport pollen between them. Flowers often have specialized structures that make the nectar accessible only for animals possessing appropriate morphological structures, and there are numerous examples of coevolution between nectarivores and the flowers they ...
