Species evenness is the relative number of individuals of each species in a given area. [181] Species richness [182] is the number of species present in a given area. Species diversity [183] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
Diversity in the ecosystem is significant to human existence for a variety of reasons. Ecosystem diversity boosts the availability of oxygen via the process of photosynthesis amongst plant organisms domiciled in the habitat.
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
This conservation scheme was designed to benefit those local communities which neighbour Indonesian forestry and to help the most endangered species living in these threatened habitats. Prior to 2015, it was named Directorate General of Forest Protection and Nature Conservation ( Direktorat Jenderal Perlindungan Hutan dan Konservasi Alam - PHKA ).
Parazoa (Parazoa, gr. Παρα-, para, "next to", and ζωα, zoa, "animals") are a taxon with sub-kingdom category that is located at the base of the phylogenetic tree of the animal kingdom in opposition to the sub-kingdom Eumetazoa; they group together the most primitive forms, characterized by not having proper tissues or that, in any case, these tissues are only partially differentiated.
Urochloa mutica, commonly known as para grass, buffalo grass, Mauritius signal grass, pasto pare, malojilla, gramalote, parana, Carib grass, and Scotch grass, is a species of grass. [ 2 ] [ 3 ] Despite its common name of California grass , [ 2 ] it does not occur in California ; [ 4 ] it is native to northern and central Africa and parts of the ...
A paraspecies (a paraphyletic species) is a species, living or fossil, that gave rise to one or more daughter species without itself becoming extinct. [1] Geographically widespread species that have given rise to one or more daughter species as peripheral isolates without themselves becoming extinct (i.e. through peripatric speciation) are examples of paraspecies.
Mutualism describes the ecological interaction between two or more species where each species has a net benefit. [1] Mutualism is a common type of ecological interaction. Prominent examples are:
