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. 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 near its b ...

Oldfield Mouse
The oldfield mouse, oldfield deermouse or beach mouse (''Peromyscus polionotus'') is a nocturnal species of rodent in the family Cricetidae. It is a species of the genus ''Peromyscus'', a closely related group of New World rats and mice, New World mice often called "deermice", that 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 2016, these mice were in the least concern category on the IUCN Red List with certain subspecies classified as extinct, critically endangered, endangered 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.

Perdido Key
Perdido Key is a barrier island on the north coast of the Gulf of Mexico. The island extends from Pensacola Pass on the east to Perdido Pass on the west. Most of the island is in Florida, with the western end of the island in Alabama. Santa Rosa Island is to the east of the island, and Alabama Point is to the west. Perdido Key was attached to the mainland until the 1940s when a canal separated it from the mainland. The eastern part of the island forms part of the Gulf Islands National Seashore, which includes the Perdido Key Historic District, the site of three shore batteries that once defended Pensacola Bay. The rest of the island, with the exception of the Perdido Key State Park, has been developed as a resort and residential community. As a barrier island, Perdidio Key is subject to changes due to wave action and longshore currents, particularly from hurricanes. The endangered Perdido Key beach mouse is endemic to the island.

Monogamy In Animals
Some animal species have a monogamous mating system, in which pairs bond to raise offspring. This is associated, usually implicitly, with sexual monogamy. Monogamous mating Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases, life-long. Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another.Ophir, Alexander G., Phelps, Steven M., Sorin, Anna Bess & O. Wolff, J. (2008)Social but not genetic monogamy is associated with greater breeding success in prairie voles/ref> As an example, in the cichlid species '' Variabilichromis moorii'', a monogamous pair will care for eggs and y ...

Burrow
file:Chipmunk-burrow (exits).jpg, 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 Animal locomotion, 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 amphipods, 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 (burrow), warren.

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, 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. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Erin (1995)
Hurricane Erin was the first hurricane to strike the contiguous United States since Hurricane Andrew in 1992. The fifth tropical cyclone, fifth named storm, and second hurricane of the unusually active 1995 Atlantic hurricane season, Erin developed from a tropical wave near the southeastern Bahamas on July 31. Moving northwestward, the cyclone intensified into a Category 1 hurricane on the Saffir–Simpson scale near Rum Cay about 24 hours later. After a brief jog to the north-northwest on August 1, Erin began moving to the west-northwest. The cyclone then moved over the northwestern Bahamas, including the Abaco Islands and Grand Bahama. Early on August 2, Erin made landfall near Vero Beach, Florida, with winds of . The hurricane weakened while crossing the Florida peninsula and fell to tropical storm intensity before emerging into the Gulf of Mexico later that day. Early on August 3, Erin re-intensified into a Category 1 hurricane. Streng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Opal
Hurricane Opal was a large and powerful tropical cyclone that caused severe and extensive damage along the northern Gulf Coast of the United States in October 1995. The fifteenth named storm, ninth hurricane and strongest tropical cyclone of the unusually active 1995 Atlantic hurricane season, Opal developed from the interaction of a tropical wave and a low-pressure area near the Yucatán Peninsula on September 27 as Tropical Depression Seventeen. The depression crossed the Yucatán Peninsula and intensified into a tropical storm on September 30. Opal intensified into a hurricane on October 2 after entering the Gulf of Mexico. The cyclone turned northeastward and strengthened significantly. By October 4, Opal was an intense , Category 4 hurricane. With a minimum pressure of , Hurricane Opal was the most intense Category 4 Atlantic hurricane on record. However, the cyclone abruptly weakened to a low-end Category 3 hurricane prior to making landfall o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 distant 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 both this agility as well as their two-toned coloring. 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 mammali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pensacola Metropolitan Area
The Pensacola metropolitan area is the metropolitan area centered on Pensacola, Florida. It is also known as the Pensacola–Ferry Pass–Brent Metropolitan Statistical Area, a metropolitan statistical area (MSA) used for statistical purposes by the United States Census Bureau and other agencies. The Pensacola Standard Metropolitan Statistical Area was first defined in 1958, with Pensacola as the principal city, and included Escambia and Santa Rosa counties. The MSA was renamed Pensacola–Ferry Pass–Brent MSA in 2003, with the unincorporated census-designated places Ferry Pass and Brent added as principal cities. The population of the MSA in the 2020 census was 511,502. The five incorporated cities within the MSA are Pensacola (Population: 54,312), Milton (10,197), Gulf Breeze (6,302), Century (1,713), and Jay (524). In addition, several unincorporated census-designated places account for a great number of the population. Most notable is Navarre (43,540); its population m ...

Mammals Described In 1968
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the larg ...
