Does Antarctica have high or low biodiversity?

With such a low NPP to start with, Antarctic ecosystems cannot develop long food chains or support large vertebrate consumers; and biodiversity is low. The largest animals supported by these ecosystems are two types of midges!

Why is Antarctica biodiversity important?

There is a growing body of evidence that Antarctic organisms, ecosystems and biodiversity are responding to climate change. The Census of Antarctic Marine Life (CAML) was invaluable in providing a baseline for the marine environment that can be used to recognize future change.

Is Antarctica diverse?

Summary: In a comprehensive assessment of Antarctic biodiversity scientists have revealed the region is more diverse and biologically interesting than previously thought.

Do polar regions have high biodiversity?

Rich in Wildlife

Polar landscapes are home to a rich diversity of wildlife, both on land and within the seas. Polar animals have evolved to survive life in the deep cold.

What is the ecosystem in Antarctica?

Antarctica is a polar desert. Terrestrial life is limited to the very small. There are no trees or shrubs, so vegetation is mainly mosses, lichens and algae.

What biodiversity means?

The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.

Is Antarctica a desert?

Antarctica is a desert. It does not rain or snow a lot there. When it snows, the snow does not melt and builds up over many years to make large, thick sheets of ice, called ice sheets. Antarctica is made up of lots of ice in the form of glaciers, ice shelves and icebergs.

What is Antarctica biodiversity?

The Antarctic continent is isolated from the rest of the world by the Southern Ocean and successful natural colonization events are rare. As a result, terrestrial biodiversity is low and comprised of simple plants (e.g. mosses, lichens, liverworts) and animals (e.g. flies, mites and springtails).

Which ecosystem has high biodiversity low biodiversity?

Estuarine areas (where rivers meet seas and oceans) have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity. Deserts, for example, contain limited numbers of species.

What are the examples of high biodiversity?

Examples of places with high biodiversity include rainforests and coral reefs, because they have many different species in an area. Less biodiverse areas include deserts, icy areas, and the bottom of the ocean. Organisms do exist in those places, but not as many as places with higher biodiversity.
