Chapter 16 - Digestive System Processes and Regulation - BIO 140 Bizarrely, one of the greatest problems is overbreeding in isolated populations for example, on South Australia's Kangaroo Island which leads to animals eating themselves out of house and home. To cope with such a diet, nature has equipped Koalas with specialised adaptations. In the span of a few hours, the pH of the stomach drops from 7.5 to 2 and then to 1.5. WWF is excited to trial specialised drones, with some models capable of planting 40,000 seeds a day, to create corridors so that koalas and other wildlife can move across a landscape fragmented by fire and land clearing, he said. Koalas are also vulnerable to dehydration. When koalas eat the Eucalyptus leaves through their mouth, the chewed Eucalyptus leaves directly reach their stomach via esophagus pipe. Koala populations are in decline due to increased human impacts on Stomach: using gastric juices break down leaves into nutrients and takes away the poison (this is why koalas are immune to eucalyptus leaves) Small intestine:special cells that collect nutrients from the plants. There the Koalas ranges and territories are usually overlapped and also the Koalas' population density is very high. They eat some of the same grains as cows, but the grains are processed differently to help the human digestive system break down the food. Lastly; the food metabolism of koalas is very slow as compared to the other animals. New technology enabled us to achieve this at a tiny fraction of the US$2.7 billion it cost to sequence the first human.

Eucalyptus leaves are very fibrous and low in nutrition, and to most animals are extremely poisonous. The average age of the male Koalas is around 12 years. Bushfires, habitat fragmentation, vehicle collisions and dog attacks all which hurt koalas have been getting worse over the last decade. (we call these primary browse trees) while a variety of other species, including some non-eucalypts, appear to be browsed occasionally or used for just sitting or sleeping in.

Many researchers argue that throughout all the ages Koalas have maintained their original physical existence. Koala and Human Interaction. However; the ability of this digestive system to extract most of the energy from stomach, the process of merycism and the storage of finely chewed food contents within their hindguts make digestive system of koalas a bit advanced as compared to the other animals.
