Conservation of species is an important sustainability goal to prevent biodiversity loss. As urbanization is expanding across the globe ...

Biodiversity Informatics can be considered to have commenced with the construction of the first computerized taxonomic databases in the early 1970s, and progressed through subsequent developing of distributed search tools towards the late 1990s including the Species Analyst from Kansas University, the North American Biodiversity Information Network NABIN, CONABIO in Mexico, INBio in Costa Rica ...
Species evenness is the relative number of individuals of each species in a given area. [1] Species richness [2] is the number of species present in a given area. Species diversity [3] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
Widely distributed and relatively undegraded ecosystems are included in this category. Theoretically, all ecosystems have some risk of collapse, just as all species face some risk of extinction. The term Least concern reflects the fact that this risk is relatively low. In practice this category is reserved for ecosystems that unambiguously meet ...
For all ecosystems except the Black Sea, the Southern Catalan Sea and, to some extent, the Southeastern Australia, the cumulative importance shifts (in R2f unit) of the indicator B/C in response to fishing pressure were high even under the lowest fishing levels. [2]
Species with an abundance of an exact power of 2 (i.e. 2,4,8,16, etc.) are conventionally considered as having 50% membership in the lower abundance class 50% membership in the upper class. Such species are thus considered to be evenly split between the two adjacent classes (apart from singletons which are classified into the rarest category).
