Habitat fragmentation relates to biodiversity loss primarily through habitat destruction and its implications.
Habitat fragmentation requires some degree of habitat destruction. Although habitat fragmentation certainly differs from total habitat destruction, there is effectively less land for biodiversity to thrive after a habitat has been fragmented. This results in since there is less of a habitat for organisms to thrive in.
After habitats are fragmented, each fragment of the once continuous habitat can only support a fraction of the population that the whole habitat could. Often, especially when species are incapable of crossing whatever obstacle fragmented the habitat, this lower carrying capacity causes many organisms to die, as the fragmented habitat transitions into its reduced carrying capacity.
Additionally, when populations are thus isolated and reduced, the lack of genetic diversity makes these populations more vulnerable to disease. Consequently, habitat fragmentation leads to a reduction in biodiversity.
Frederic Clements in 1916 coined the term ‘biome’ to designate natural combination of plants and animals in a community. Thank You, Dr B K Mishra, India, Patna.
The natural ecosystem of the biosphere is termed as ‘biome.’ As we know that this term is applied to the community over a large geographical region. It is also supported by Victor Shelford (1932). A biome is a climatic climax. The animals of the biome are termed as permeants by Victor Shelford. We can say each major ecosystem of terrestrial or aquatic habitats as biome. Based on the habitats broadly we divide the biomes into the following categories.
Aquatic Biomes; and
Aqua-Terrestrial Biomes. Thank You, Dr B K Mishra, Patna, India
