Antelope Jackrabbit
The antelope jackrabbit (''Lepus alleni''), also known as Allen's hare, is a species of North American hare in the family Leporidae found in southern Arizona and northwestern Mexico. Considered the "handsomest" of the hares, it occupies dry desert areas and was one of the last of the North American mammals to be formally described. Taxonomy and etymology Subspecies The antelope jackrabbit has three recognized subspecies: Evolutionary history Fossil evidence places the genus ''Lepus'' in North America approximately 2.5 million years ago. A now extinct jackrabbit species, ''Lepus giganteus'', was thought to exist in North America during this time. This species shared similar physical traits with the antelope jackrabbit, making it difficult to differentiate fossils of the two species. In a 2014 study, researchers hypothesized that ''L. giganteus'' served as a common ancestor to the antelope jackrabbit and black-tailed jackrabbit. The black-tailed jackrabbit coexists with ...

Mazatlán
Mazatlán () is a city in the Mexican list of states of Mexico, state of Sinaloa. The city serves as the municipal seat for the surrounding , known as the Mazatlán Municipality. It is located on the Pacific Ocean, Pacific coast across from the southernmost tip of the Baja California peninsula. is a Nahuatl word for 'place of deer'. The city was colonized in 1531 by the Conquistadors where many indigenous peoples of the Americas, indigenous people lived. By the mid-19th century, a large group of immigrants arrived from Germany. Over time, Mazatlán developed into port of Mazatlán, a commercial seaport, importing equipment for the nearby gold and silver mines. It served as the capital of Sinaloa from 1859 to 1873. The German Mexicans, German settlers also influenced the local music, banda music, banda, with some genres being an alteration of Bavarian folk music. The settlers established the Pacífico (beer), Pacifico Brewery on 14 March 1900. Mazatlán has a rich culture and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympatry
In biology, two closely related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter each other. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and ...

Mammalian Species
''Mammalian Species'' is a peer-reviewed scientific journal published by Oxford University Press on behalf of the American Society of Mammalogists. The journal publishes accounts of 12–35 mammal species yearly. The articles summarize the current literature about each mammal and its systematics, genetics, fossil history, distribution, anatomy, physiology, behavior, ecology, and conservation is described. The journal was established in 1969. The current editor-in-chief is Meredith J. Hamilton (Oklahoma State University–Stillwater).

Antelope Jackrabbit-2
The term antelope refers to numerous extant or recently extinct species of the ruminant artiodactyl family Bovidae that are indigenous to most of Africa, India, the Middle East, Central Asia, and a small area of Eastern Europe. Antelopes do not form a monophyletic group, as some antelopes are more closely related to other bovid groups, such as bovines, goats, and sheep, than to other antelopes. A stricter grouping, known as the true antelopes, includes only the genera ''Gazella'', ''Nanger'', ''Eudorcas'', and ''Antilope''. One North American mammal, the pronghorn or "pronghorn antelope", is colloquially referred to as the "American antelope", despite the fact that it belongs to a completely different family (Antilocapridae) than the true Old-World antelopes; pronghorn are the sole extant member of an extinct prehistoric lineage that once included many unique species. Although antelope are sometimes referred to, and easily misidentified as, "deer" (cervids), true deer are only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Mead National Recreation Area
Lake Mead National Recreation Area is a U.S. national recreation area in Southeastern Nevada and Northwestern Arizona. Operated by the National Park Service, Lake Mead NRA follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin, Nevada and Bullhead City, Arizona. It includes all of the eponymous Lake Mead as well as the smaller Lake Mohave – reservoirs on the river created by Hoover Dam and Davis Dam, respectively – and the surrounding desert terrain and wilderness. Formation of Lake Mead began in 1935, less than a year before Hoover Dam was completed. The area surrounding Lake Mead was protected as a bird refuge in 1933 and later established as the Boulder Dam Recreation Area in 1936 and the name was changed to Lake Mead National Recreation Area in 1947. In 1964, the area was expanded to include Lake Mohave and its surrounding area and became the first National Recreation Area to be designated as ...

Florence, Arizona
Florence ( O'odham: S-auppag) is a town in Pinal County, Arizona, United States. Florence, which is the county seat of Pinal County, is one of the oldest towns in that county and includes a National Historic District with over 25 buildings listed on the National Register of Historic Places. The population of Florence was 26,785 at the 2020 census. History The area where the current town of Florence is located was once inhabited by the Hohokam, ancestors of the O'odham people. Prior to the establishment of the town, the Gila River served as a part of the border between the United States and Mexico. In 1853, the Gadsden Purchase extended American territory well south of the Gila. Levi Ruggles, a veteran of the American Civil War, founded the town of Florence on the south bank of the Gila River. He came to Arizona Territory in 1866 as a U.S. Indian Agent. Recognizing the agricultural potential of the valley, he found an easily fordable crossing on the Gila River and surveyed a ...

Sierra Madre Occidental
The Sierra Madre Occidental is a major mountain range system of the North American Cordillera, that runs northwest–southeast through northwestern and western Mexico, and along the Gulf of California. The Sierra Madre is part of the American Cordillera, a chain of mountain ranges (cordillera) that consist of an almost continuous sequence that form the western "sounds" of North America, Central America, South America, and West Antarctica. Etymology The Spanish name ''sierra madre'' means "mother mountain range" in English, and ''occidental'' means "western", these thus being the "Western mother mountain range". To the east, from the Spanish ''oriental'' meaning "eastern" in English, the Sierra Madre Oriental range or "Eastern mother mountain range" runs generally parallel to the Sierra Madre Occidental along eastern Mexico and the Gulf of Mexico. The range extends from northern Sonora, a state near the Mexico–U.S. border at Arizona, southeast towards to the Trans-Mexican V ...

Sky Island
Sky islands are isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau and has extended to similarly isolated high-elevation forests. The isolation has significant implications for these natural habitats. Endemism, altitudinal migration, and relict populations are some of the natural phenomena to be found on sky islands. The complex dynamics of species richness on sky islands draws attention from the discipline of biogeography, and likewise the biodiversity is of concern to conservation biology. One of the key elements of a sky island is separation by physical distance from the other mountain ranges, resulting in a habitat island, such as a forest surrounded by desert. Some sky islands serve as refugia for boreal species stranded by warming climates since the last glacial period. In other cases, localized populations of plants and animals tend towards speciation, similar to oceanic isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
