What is an ACTH test? Adrenocorticotropic hormone (ACTH) is a hormone produced in the anterior, or front, pituitary gland in the brain. The function of ACTH is to regulate levels of the steroid hormone cortisol, which released from the adrenal gland.
Koalas live in eucalypt woodlands and forests. Home range size varies according to quality of habitat, ranging from less than two hectares to several hundred hectares. Koalas are found between south-eastern South Australia and Queensland, but only where enough suitable trees have been left. The largest koalas weigh over 10 kilograms and are found in Victoria, while the smallest live in North Queensland and weigh only 5.5 kilograms. In NSW, koalas mainly live on the central and north coasts, with some populations west of the Great Dividing Range, on the south coast and on the southern tablelands. Most populations live in isolated habitats and many areas in which koalas are most abundant are subject to intense pressures.
From Bill Phillips: 'The little Australians we'd all hate to lose'. By 1924 Koalas were extinct in South Australia, severely depleted in New South Wales, and estimates for Victoria go as low as 500 animals. At this time, the focus of the fur trade moved north to Queensland.
