Perdido Key Beach Mouse
The Perdido Key beach mouse (''Peromyscus polionotus trissyllepsis'') is an endangered subspecies of the oldfield mouse. It is found on Perdido Key, Florida. The small white and gray mouse, weighing only , blends in well with the white quartz sand of northern Gulf coast beaches. Diet Dune plants are the primary source of food for the species. It feeds primarily on the seeds of sea oats and bluestem, but will occasionally eat insects. Unlike other rodents they shun people and will not eat or be near trash. Reproduction The Perdido Key beach mouse is a nocturnal animal, spending most daylight hours in their burrows. Unlike many species, beach mice are monogamous, with mated pairs tending to remain together as long as both live. A typical beach mouse pair averages 3–4 offspring per litter and has roughly 3 litters per year. Shelter In contrast to its inland relatives, the Perdido Key beach mouse avoids humans, buildings and trash, instead preferring to meander among the dunes n ...

Oldfield Mouse
The oldfield mouse or beach mouse (''Peromyscus polionotus''), is a nocturnal species of rodent in the family Cricetidae and primarily eats seeds. It lives in holes throughout the Southeastern United States in beaches and sandy fields. Predators to these mice include birds and mammals. In 2010, these mice were in the least concern category on the IUCN Red List with certain subspecies classified as extinct or near threatened. Distribution and habitat The oldfield mouse occurs only in the southeastern United States, ranging from Florida to Tennessee. They primarily live in beaches and sandy fields.Whitaker 1998, p. 308 Description The mouse has fawn-colored upperparts and grey to white underparts through most of its range, but on white sandy beaches, the mouse is light or even white. Inland populations are darker and smaller with shorter tails that are dusky above and white below. General body and tail color may vary slightly depending upon geographical location. Behavior The mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perdido Key, Florida
Perdido Key is an unincorporated community in Escambia County, Florida, United States, between Pensacola, Florida and Orange Beach, Alabama. "Perdido" means "lost" in the Spanish and Portuguese languages. The community is located on and named for Perdido Key, a barrier island in northwest Florida and southeast Alabama. The Florida district of the Gulf Islands National Seashore includes the east end of the island, as well as other Florida islands. No more than a few hundred yards wide in most places, Perdido Key stretches some from near Pensacola to Perdido Pass Bridge near Orange Beach. History From the beginning of the 17th century, Spanish and French explorers, imagining riches in the New World, began colonizing the northern coast of the Gulf of Mexico. A Spanish expedition from Vera Cruz, Mexico had settled on what became known as Santa Rosa Island on Panzacola Bay, named after the indigenous people, later known as the Pensacola Indians. Panzacola means "the village of hair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monogamy
Monogamy ( ) is a form of dyadic relationship in which an individual has only one partner during their lifetime. Alternately, only one partner at any one time (serial monogamy) — as compared to the various forms of non-monogamy (e.g., polygamy or polyamory). The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time. A monogamous relationship can be sexual or emotional, but it's usually both. Many modern relationships are monogamous. Terminology The word ''monogamy'' derives from the Greek μονός, ''monos'' ("alone"), and γάμος, ''gamos'' ("marriage").Cf. "Monogamy" in ''Britannica World Language Dictionary'', R.C. Preble (ed.), Oxford-London 1962, p. 1275:''1. The practice or principle of marrying only once. opp. to digamy now ''rare'' 2.

Burrow
An Eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interactions. Many animal species are known to form burrows. These species range from small invertebrates, such as the ''Corophium arenarium'', to very large vertebrate species such as the polar bear. Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length; an example of the latter level of complexity, a well-developed burrow, would be a rabbit warren. Vertebrate burrows A large variety of vertebrates construct or use burrows in many t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
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 and invasive species. 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. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Peromyscus
''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" (coined in 1833) is in reference to this agility. The most common species of deer mice in the continental United States are two closely related species, '' P. maniculatus'' and '' P. leucopus''. In the United States, ''Peromyscus'' is the most populous mammalian genus overall, and has become notorious in the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Described In 1968
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...
