The Koala

Koala production Koala is an Australian jewel. It has very furry gray hair, black nose like rubber, sharp nails, ambiguous ear, and gray personality, or I have corerity to say. As you kill the koala, you can lose a million furs. They sell fur to a coat company and coat with koala fur. Well, sadly, too many people made millions of koalas. This is the reason they are endangered species. Habitat is distributed in semi-tropical forests along the eastern coast of Australia, such as North Queensland State, New South Wales State, Victoria State, a small region in the south of Australia.

Although it is understood that the genetic diversity of koalas is low in modern population, the historical report shows that the population of koalas is outdated. When the Europeans first noticed Koalas in the late 18th century, they noticed that the number of these newly described species (originally called Lipurus cinereus) was very low for Aboriginal hunting. Instead, hunting reduced the koala and became an ordinary animal in the mid-nineteenth century. Researchers in Germany, Denmark, and the United States compared modern koalas mitochondrial DNA with 14 museum specimens around the world (the date of the specimen is known), and the change in population size is related to the genetic diversity of koalas I understand how it affects. There are 14 old koalas with different places and times, but they each have only one of four different haplotypes (mutations in mtDNA hypervariable regions). They are all found in modern koalas. found

Traditionally, three different subspecies have been recognized: Queensland Koala (P. c. Adustus, Thomas 1923), New South Wales Koala (P. c. Cinereus, Goldfuss 1817) and Victorian Koala (P c). Victor, Troughton 1935). These forms are characterized by the color and thickness of the fur, the shape of the body, and the shape of the skull. Queensland Koala is the smallest silver coat out of the three and short skull. The Victorian koala is the largest, with a brighter brown fur and a wider skull. The boundaries of these changes are based on the border, and their position as a subspecies is controversial. Genetic studies in 1999 showed that these mutations represent a diverse group of genes with limited gene flow among them, and that these three subspecies are single in the importance of evolution It is shown that it constitutes a unit. Other studies have found that the koala population has high levels of inbreeding and low genetic variation.

In the past, koalas were killed because of his clothes. Indeed, from 1919 to 1924, 8 million koalas were killed. Today, koalas are threatened by looting their dogs and diseases infected by most people. In addition, some koala turned over with a car. However, it is the loss of habitat that koalas and other wildlife can not protect themselves. We need to work together to manage the care plan to ensure the survival of koalas and to study and support habitat protection programs
