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.
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 ).
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perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
Crop pollinating insects are worth annually $14.6 billion to the US economy [9] and the cost to hand pollinate over insect pollination is estimated to cost $5,715-$7,135 more per hectare. Not only will there be a cost increase but also an decrease in colony fitness, leading to a decrease in genetic diversity, which studies have shown has a ...
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. [1] Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered.
Bruguiera gymnorhiza, the large-leafed orange mangrove or oriental mangrove, [3]) is a mangrove tree that grows usually to 7–20 metres (23–66 ft) high, but sometimes up to 35m, that belongs to the family Rhizophoraceae.
The group may be treated as an unranked clade, [1] a division under the name Euphyllophyta [2] or a subdivision under the name Euphyllophytina. [3] The euphyllophytes are characterized by the possession of true leaves ("megaphylls"), and comprise one of two major lineages of extant vascular plants. [ 4 ]
Proboscis monkeys, the world's largest monkey, [1] are a langur species endemic to Borneo. [5] Macaque species include the crab-eating macaque and the pig-tailed macaque. [1] The Malayan tiger, a close relative of the Indochinese tiger, is endemic to the Malay peninsula [4] with a remaining population of about 300 (250-340). [6]
