Peromyscus is a genus of rodents. They are commonly referred to as deer mice or deermice, not to be confused with the chevrotain or "mouse deer". They are New World mice only distantly related to the common house and laboratory mouse, Mus musculus. From this relative, Peromyscus species are distinguished by relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring. In reference to the coloring, the word Peromyscus comes from Greek words meaning "booted mouse". They are also accomplished jumpers and runners by comparison to house mice, and their common name of "deer mouse" is in reference to this agility.
The Apache trout or Arizona trout, is a species of freshwater fish in the salmon family of order Salmoniformes. It is one of the Pacific trouts.
The pallid beach mouse or Ponce de Leon beach mouse, is an extinct subspecies of the oldfield mouse that was endemic to Florida in the United States.
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).
The salt-marsh harvest mouse, also known as the red-bellied harvest mouse, is an endangered rodent endemic to the San Francisco Bay Area salt marshes in California.
Preble's meadow jumping mouse is a subspecies of meadow jumping mouse, endemic to the upland habitats of Colorado and Wyoming in North America. It is found nowhere else in the world. It is listed as Threatened under the United States Endangered Species Act; there is a major debate about whether it is a valid taxon.
The Alabama beach mouse is a federally endangered subspecies of oldfield mouse that lives along the Alabama coast.
In 1999, the Guana Tolomato Matanzas National Estuarine Research Reserve was designated in St. Johns and Flagler counties, Florida as a part of the National Oceanic and Atmospheric Administration (NOAA) National Estuarine Research Reserve (NERR) system. The GTM Research Reserve represents the east Florida sub-region of the Carolinian bioregion. It is one of 30 NERRs in 23 states and one territory. GTM is one of three NERRs in Florida and is administered on behalf of the state by the Florida Department of Environmental Protection's Florida Coastal Office as part of a network that includes forty-one aquatic preserves, three NERRs, a National Marine Sanctuary, the Coral Reef Conservation Program and the Florida Oceans and Coastal Council. Additional interests are held in the research and management of the GTM and connected preserved or conserved lands including:
The Anastasia Island beach mouse is a subspecies of the oldfield mouse of the southeastern United States. It occurs in the sand dunes of Florida beaches. It has been classified by the United States Fish and Wildlife Service as an endangered species due to the specificity of its habitat and the natural and human-induced destruction thereof.
The cotton mouse is a species of rodent in the family Cricetidae found in the woodlands of the US South.
The Jemez Mountains salamander is a species of salamander in the family Plethodontidae endemic to New Mexico in the United States. Its natural habitat is temperate forests. It is threatened by habitat loss, is in rapid decline, and was placed on the IUCN Red List in 2013.
The Scioto madtom was a species of fish in the family Ictaluridae. It is listed as extinct by the International Union for Conservation of Nature, which notes that it has likely been entirely or functionally extinct since 1957 given the lack of records since that year.
Epioblasma othcaloogensis, the southern acornshell or southern acorn riffle shell, was a species of freshwater mussel in the family Unionidae. It was only known from the Coosa and Cahaba Rivers of the southeastern United States.
Epioblasma turgidula, the turgid blossom pearly mussel, turgid riffle shell, turgid-blossom naiad or turgid blossom, was a species of freshwater mussel, a mollusk in the family Unionidae. The US Fish and Wildlife Service declared the species extinct and delisted it from the Endangered Species Act in 2023.
Pleurobema taitianum, the heavy pigtoe or Judge Tait's mussel, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
The Perdido Key beach mouse is an endangered subspecies of the oldfield mouse. It is found on Perdido Key. The small white and gray mouse, weighing only 13–16 g (0.46–0.56 oz), blends in well with the white quartz sand of northern Gulf coast beaches.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Sierra Club v. Babbitt, 15 F. Supp. 2d 1274, is a United States District Court for the Southern District of Alabama case in which the Sierra Club and several other environmental organizations and private citizens challenged the United States Fish and Wildlife Service (FWS). Plaintiffs filed action seeking declaratory injunctive relief regarding two incidental take permits (ITPs) issued by the FWS for the construction of two isolated high-density housing complexes in habitat of the endangered Alabama beach mouse. The District Court ruled that the FWS must reconsider its decision to allow high-density development on the Alabama coastline that might harm the endangered Alabama beach mouse. The District Court found that the FWS violated both the Endangered Species Act (ESA) and the National Environmental Policy Act (NEPA) by permitting construction on the dwindling beach mouse habitat.
The Key Largo cotton mouse is a subspecies of rodent in the family Cricetidae. The subspecies is endemic to Key Largo in the upper Florida Keys. It is a slightly larger mouse with a more reddish color than other mouse species from mainland Florida. The Key Largo cotton mouse can breed throughout the year and has an average life expectancy of five months.
