Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers .
This information can then be used to better understand the environment, its ecology, the behaviour of species and how organisms interact with one another and their environment. Here is a list of some sampling techniques and equipment used in environmental sampling: Quadrats - used for plants and slow moving animals [2] [3]
In forest reserves, rights to activities like hunting and grazing are sometimes given to communities living on the fringes of the forest, who sustain their livelihood partially or wholly from forest resources or products. Approximately 50 million hectares (or 24%) of European forest land is protected for biodiversity and landscape protection.
The Living Planet: A Portrait of the Earth is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the UK from 19 January 1984. The sequel to his pioneering Life on Earth , it is a study of the ways in which living organisms, including humans , adapt to their surroundings.
Such creatures evolved further and learned to use flint for weapons, animal skins for clothing, and fire for warmth and preparing food. Their brains became fully formed and, using the walls of their caves as a canvas, they painted and eventually learned to write. Homo sapiens had arrived. However, Attenborough warns, just because humans have ...
The community of living organisms in conjunction with the nonliving components (e.g., water, light, radiation, temperature, humidity, atmosphere, acidity, and soil) of their environment is called an ecosystem.
All organisms are adapted to their environment to a greater or lesser extent. If the abiotic and biotic factors within a habitat are capable of supporting a particular species in one geographic area, then one might assume that the same species would be found in a similar habitat in a similar geographic area, e.g. in Africa and South America ...
Marine habitats can be broadly divided into pelagic and demersal habitats. Pelagic habitats are the habitats of the open water column, away from the bottom of the ocean. Demersal habitats are the habitats that are near or on the bottom of the ocean. An organism living in a pelagic habitat is said to be a pelagic organism, as in pelagic fish.
