A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. [1] [2] ...
Biodiversity hotspots across the world Several international organizations focus their conservation work on areas designated as biodiversity hotspots . According to Conservation International , to qualify as a biodiversity hotspot a region must meet two strict criteria:
Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms (biodiversity) and abiotic properties such as nonliving things like water or soil (geodiversity). It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.
Biodiversity is most commonly used to replace the more clearly-defined and long-established terms, species diversity and species richness. [13] However, there is no concrete definition for biodiversity, as its definition continues to be defined. Other definitions include (in chronological order):
Hotspot ecosystems support high species diversity, numbers of individuals, or both, and are therefore important in maintaining margin-wide biodiversity and abundance. [9] HERMIONE research ranges from investigation of the ecosystems' dimensions, distribution, interconnection and functioning, to understanding the potential impacts of climate ...
Most of the exponential human population growth worldwide is occurring in or close to biodiversity hotspots. [6] This may explain why human population density accounts for 87.9% of the variation in numbers of threatened species across 114 countries, providing indisputable evidence that people play the largest role in decreasing biodiversity. [18]
An additional 10 hotspots were added subsequently. [24] [25] The concept of biodiversity hotspots designates those areas most important from the point of view of biodiversity, and is of special importance to endemic species. The designated 35 hotspots harbour over 50% of the world's endemic plant species and 42% of all endemic terrestrial ...
Thus meaning, it covers; the patch areas, edge effects, and patch shape complexity. [ 6 ] In scientific literature, there is some debate whether the term "habitat fragmentation" applies in cases of habitat loss , or whether the term primarily applies to the phenomenon of habitat being cut into smaller pieces without significant reduction in ...
