A diversity index is a method of measuring how many different types (e.g. species) there are in a dataset (e.g. a community). Some more sophisticated indices also account for the phylogenetic relatedness among the types. [1]
Batang Gadis is a national park covering 1,080 km 2 in North Sumatra province, Indonesia extending between 300 and 2,145 metres altitude. It is named after the Batang Gadis river that flows through the park. [1] Signs of the endangered Sumatran tiger and the threatened Asian golden cat, leopard cat and clouded leopard were seen in the park.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. [ 1 ] A series of Regional Red Lists, which assess the risk of extinction to species within a ...
Acropora indonesia. Acropora indonesia is a species of acroporid coral that was first described by Dr Carden Wallace in 1997. Found in marine, tropical, shallow reefs in sheltered flat locations or gentle slopes, it occurs at depths of 10 to 20 m (33 to 66 ft). It is listed as a vulnerable species on the IUCN Red List, and it is thought to have ...
Mamberamo Foja Wildlife Reserve. Mamberamo Foja Wildlife Reserve is a large protected area on New Guinea, in Indonesia 's Papua Province. It covers an area of 16,610 km 2, [1] and extends along the Mamberamo River and its tributaries from the foothills of the Central Range to the Pacific Ocean. [2]
Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness[ 181 ] is the relative number of individuals of each species in a given area.
The Coral Triangle (CT) is a roughly triangular area in the tropical waters around the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands and Timor-Leste. This area contains at least 500 species of reef-building corals in each ecoregion. [3] The Coral Triangle is located between the Pacific and Indian oceans [4] and ...
As a multifaceted field of study, zoogeography incorporates methods of molecular biology, genetics, morphology, phylogenetics, and Geographic Information Systems (GIS) to delineate evolutionary events within defined regions of study around the globe. As proposed by Alfred Russel Wallace, known as the father of zoogeography, phylogenetic ...
