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. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
Presbytis is a genus of Old World monkeys also known as langurs, leaf monkeys, or surilis. Members of the genus live in the Thai-Malay Peninsula, on Sumatra, Borneo, Java and smaller nearby islands.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as Critically Endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.
Functional extinction is the extinction of a species or other taxon such that:
- It disappears from the fossil record, or historic reports of its existence cease;
- The reduced population no longer plays a significant role in ecosystem function;
- The population is no longer viable. There are no individuals able to reproduce, or the small population of breeding individuals will not be able to sustain itself due to inbreeding depression and genetic drift, which leads to a loss of fitness.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
Ameles decolor is a species of small praying mantis native to the west Mediterranean and North Africa. A. decolor was first described by entomologist Domenico Cyrillo in 1787, and its current classification was established in 1976 by Karl Harz and Alfred Peter Kaltenbach. A. decolor presents as a small, light brown mantis with females tending to appear larger than their male counterparts. The mating patterns of A. decolor are considered some of the most complex amongst praying mantises, with males presenting two different styles of courtship. Their habitat favours shrublands, grasslands, and wooded areas.
Ameles spallanzania, common name European dwarf mantis, is a species of praying mantis.
Ameles is a wide-ranging genus of praying mantises represented in Africa, Asia, and Europe.
Ameles assoi is a species of praying mantis native to Morocco, Tunisia, and Spain.
