Ecosystems at risk essay

Drought, floods, fires, earthquakes and landslide are all examples of catastrophic changes affecting ecosystems.

The vulnerability and resilience of an ecosystem occurs due to both natural stresses and human-induced modifications. Biodiversity of ecosystems also includes the species diversity and ecosystem diversity which both refer to individual ecosystems in terms of habitat differences, biotic communities, the number of species at each trophic level and the variety of ecological processes.

S to Fraser Island in the south 24? Climate change, oil spills, tourism, overfishing, land clearing, sewage and waste disposal, coral harvesting and dredging and sand mining have all been major human impacts on the Great Barrier Reef.

Tropical cyclones are a major source of damage to this reef system. All ecosystems are vulnerable but vary in their sensitivity to change, some of the causes of vulnerability include biodiversity, extent, linkages and location.

This is known as natural selection. Catastrophic rates of change impact environments and ecosystems instantly and cause disturbances in these ecosystems. Another ecosystem at risk is coastal dunes.

These processes massively impact upon the ecosystem, due to if the level of biodiversity is greatly diminished the functioning of the ecosystem is put at risk. The Great Barrier Reef is a highly active ecosystem.

Vulnerability within an ecosystem refers to its sensitivity to stresses that can upset the ecological dynamic equilibrium. Coastal dunes are defined as large accumulations of sand located immediately behind the active beach zone. They bring large amounts of fresh water onto the reef though forceful rain.

Biodiversity of ecosystems is based on the diversity and variety of genetic information contained in all microorganisms, plants and animals within the specific area. The greater the diversity within an ecosystem the more robust it is, as the species have more chance of surviving if a destructive event were to occur, consequently this results in it being less vulnerable.

The Great Barrier Reef is a huge, complex ecosystem located off the east coast of northern Queensland and is considered as an ecosystem at risk.

It has of the worlds 13 fish pecies in it area, bird species, 5oo species of seaweed, species of echinoderm, species of shark and ray and around species of hard coral. The state of equilibrium is a product of the biophysical interactions that take place in an ecosystem.Ecosystems at Risk The ecosystem at risk that I have chosen to research is the Himalayan Mountain range.

Considering the mountain range covers a very large area, the ecosystem type has been narrowed down to the Alpine variety.
