The Outback is the colloquial name for the vast, unpopulated and mainly arid areas that comprise Australia’s interior and remote coasts. The Red Centre, in the Northern Territory, exemplifies the Outback. Its gateway is the isolated town of Alice Springs and its landmarks include Uluru, Australia's iconic red-rock monolith. In the north, Kakadu National Park has Aboriginal rock paintings and billabong oxbow lakes

Plant Litter (is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility)

Off to work........................

Quercus species (Oaks) provide critical ecosystem services that contribute to human well-being. Ecosystem services are those aspects of nature that are fundamental to the welfare of people by provisioning consumable goods (food, shelter), regulating the environment,or enhancing human culture and aesthetics. Provisioning services of oaks are well recognized. oaks have played in developing civilization throughout the ages. Oak trees have provisioned humans with goods and services for millennia from the ink for writing that comes from tannins in the bark, and ship construction that allowed ocean travel, to wagons, barrels, homes, and acorns as food sources.

Rainforest are forests characterized by high and continuous rainfall, with annual rainfall in the case of tropical rainforests between 2.5 and 4.5 meters (98 and 177 in) and definitions varying by region for temperate rainforests. Tropical rainforests provide timber as well as animal products such as meat and hides. Rainforests usually have extremely dense ecosystems because there are so many different types of animals, all are living in a very small area.

A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater.

Terrestrial ecosystem - is a type of ecosystem found only on land forms. Six primary terrestrial ecosystems exist: tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, deserts.

Umbrella Species (are species selected for making conservation-related decisions, typically because protecting these species indirectly protects the many other species that make up the ecological community of its habitat. Species conservation can be subjective because it is hard to determine the status of many species. With millions of species of concern, the identification of selected keystone species, flagship species, or umbrella species makes conservation decisions easier. Umbrella species can be used to help select the locations of potential reserves, find the minimum size of these conservation areas or reserves, and to determine the composition, structure, and processes of ecosystems)

Vulnerable ecosystems:

Three major dimensions of vulnerability are involved:

• exposure to stresses, perturbations, and shocks;
• the sensitivity of people, places, ecosystems, and species to the stress or perturbation, including their capacity to anticipate and cope with the stress;
• and the resilience of the exposed people, places, ecosystems, and species in terms of their capacity to absorb shocks and perturbations while maintaining function.

Most vulnerable to climatic change

Wildlife Corridor (is an area of habitat connecting wildlife populations separated by human activities or structures (such as roads, development, or logging). This allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding and reduced genetic diversity (via genetic drift) that often occur within isolated populations. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to random events (such as fires or disease))

Xenotransplantation, or heterologous transplant, is the transplantation of living cells, tissues or organs from one species to another. Such cells, tissues or organs are called xenografts or xenotransplants.
