Herring are various species of forage fish, belonging to the order Clupeiformes.
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable".
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.
Speke's gazelle is the smallest of the gazelle species. It is confined to the Horn of Africa, where it inhabits stony brush, grass steppes, and semi deserts. This species has been sometimes regarded as a subspecies of the Dorcas gazelle, though this is now widely disregarded. Severe habitat fragmentation means it is now impossible to assess the natural migratory or nomadic patterns of G. spekei. Its numbers are under threat, and despite an increase in population, the IUCN in 2007 announced its status had changed from vulnerable to endangered. A captive population is maintained, and the wild population exists in the lower tens of thousands. As of 2008, this gazelle is classified as endangered under the IUCN Red List.
The Bornean yellow muntjac is a muntjac deer species, endemic to the moist forests of the island of Borneo.
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).
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or conservation dependent.
The Sunda scops owl is a small brown owl native to the Sunda Islands.
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.
Villa's gray shrew is a shrew native to northeastern Mexico, where it is called musaraña.
The Bornean water shrew is a species of mammal in the family Soricidae. It is endemic to Malaysia. Its natural habitat is rivers.
The lesser forest shrew is a species of mammal in the family Soricidae endemic to northeastern Democratic Republic of the Congo, where its type locality is at Medje. Its natural habitat is subtropical or tropical moist lowland forest.
The rain forest shrew is a species of mammal in the family Soricidae endemic to Cameroon. Its natural habitat is subtropical or tropical moist lowland forest. It is known only from its type locality, and from Kongana, Central African Republic.
The Hainan Island shrew is a species of mammal in the family Soricidae native to China and Vietnam. The IUCN has insufficient data to assess the level of population and its trend.
The Vordermann's pipistrelle is a species of vesper bat found in Brunei Darussalam, Indonesia, and Malaysia. It was described in 1890 by the Dutch zoologist Fredericus Anna Jentink, who named it after its discoverer, the Dutch physician Adolphe Vorderman.
The Vietnam ferret-badger is a member of the family Mustelidae native to Vietnam. It was described in 2011 and is known from only two specimens.
Andrew Rebori's house bat is a species of bat found in Africa.
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
Urva is a genus comprising the Asian mongooses within the mongoose family Herpestidae. Species in the genus were formerly classified in the genus Herpestes, which is now thought to comprise exclusively African mongooses; phylogenetic evidence indicates that the Asian mongooses form a monophyletic group and had an Asian common ancestor. Urva forms a clade with Xenogale and Atilax, while Herpestes forms a clade with all other African mongoose species.
