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 Paraguaian hairy dwarf porcupine, Coendou spinosus, is a South American porcupine species from the family Erethizontidae. It is found in Argentina, Brazil, Paraguay and Uruguay.
The black-tailed hairy dwarf porcupine, Coendou melanurus, is a South American porcupine species from the family Erethizontidae. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname and Venezuela.
The Bahia porcupine, Coendou insidiosus, is a New World porcupine species in the family Erethizontidae endemic to the Atlantic Forest of southeastern Brazil. It was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. Sphiggurus pallidus, formerly considered a separate species but known from two young specimens only, is a synonym of this species.
Roosmalen's dwarf porcupine, Coendou roosmalenorum, is a porcupine species from the New World porcupine family likely endemic to northern Brazil. Only three specimens were known at the time, and only one had a collection locality. It is named for Marc van Roosmalen and his son Tomas, whose collections from the middle Madeira included the first known specimens. It was soon assigned to the genus Sphiggurus, although this genus was not recognized by the authors. Genetic studies in 2013 have since showed Sphiggurus to be polyphyletic. Nonetheless it is commonly classified as Sphiggurus roosmalenorum. Coendou roosmalenorum may be misspelled due to a conflicting basionym combination.
A conservation-dependent species is a species which has been categorised as "Conservation Dependent" ("LR/cd") by the International Union for Conservation of Nature (IUCN), i.e. as dependent on conservation efforts to prevent it from becoming vulnerable to endangerment. Such species must be the focus of a continuing species-specific and/or habitat-specific conservation programme, the cessation of which would result in the species qualifying for one of the threatened categories within a period of five years.
Canthocamptus is a genus of copepods that live in water from the Arctic Ocean to the Atlantic Ocean. There are over 200 different species of Canthocamptus. A number of Australian endemic species are listed as vulnerable species on the IUCN Red List, and one Brazilian species is conservation dependent.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.
The stump-tailed porcupine is a species of rodent in the family Erethizontidae. It is found mainly in Colombia, with a few records from Ecuador.
The Mexican hairy dwarf porcupine or Mexican tree porcupine is a species of rodent in the family Erethizontidae. It is found in Costa Rica, El Salvador, Guatemala, Honduras, Panama, Mexico, Nicaragua and Belize.
The brown hairy dwarf porcupine is a species of rodent in the family Erethizontidae. Found in the Andes in Colombia and Venezuela, its natural habitat is subtropical or tropical moist lowland forests. It is not easy to study as it is only known from a few specimens and wasn't recorded from 1925 until the 2000s. The porcupine is nocturnal and arboreal, feeding on leaves, shoots, and fruits. Habitat loss severely threatens it and it may even be extinct. Formerly listed as vulnerable, it is now designated data deficient. It is not known from any protected areas or conservation measures.
Harpagoxenus is a genus of ants in the subfamily Myrmicinae. Found in the Palaearctic and Nearctic ecozones of the world, Harpagoxenus was first established as Tomognathus by Mayr (1861) to house the species Myrmica sublaevis. However, the name had already been used (homonym) for a genus of fish, and was replaced with its current name by Forel (1893).
Harpagoxenus sublaevis is a species of ant in the subfamily Myrmicinae. It is found in Austria, France, Germany, Italy, and Switzerland.
Canthocamptus longipes is a species of crustacean in the family Canthocamptidae. It is endemic to Australia.
Fibulacamptus is an Australian endemic genus of crustacean in the family Canthocamptidae. Two of the four species are listed as vulnerable species on the IUCN Red List :
The streaked dwarf porcupine, Coendou ichillus, is a porcupine species in the family Erethizontidae. It is known from the lowlands of eastern Ecuador, and may be present in Peru as well. It appears to be nocturnal and arboreal in its habits.
The frosted hairy dwarf porcupine, Coendou pruinosus, is a porcupine species in the family Erethizontidae from Colombia and northern and eastern Venezuela. It was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. The species lives in lowland tropical rainforest and cloud forest at elevations from 50 to 2,600 meters. Its karyotype has 2n = 42 and FN = 76. Its closest relative is the brown hairy dwarf porcupine.
The Andean porcupine or Quichua porcupine is a species of rodent in the family Erethizontidae. It is found in the Andes of northern Ecuador and Colombia as well as in Panama. This porcupine is little known, but is probably arboreal, nocturnal and solitary like its relatives. The species is thought to be uncommon to rare and the population decreasing. It is threatened by deforestation, habitat fragmentation and agriculture.
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 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 (CR). In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered (EN) worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
