Mexican Mole
The Mexican mole (''Scapanus anthonyi'') is a species of mammal in the family Talpidae. It is endemic to Baja California in Mexico, where it is restricted to the highlands of the Sierra de San Pedro Mártir mountain range. Its specific epithet references naturalist Alfred Webster Anthony. It was previously thought to be a subspecies of the broad-footed mole (''S. latimanus'', but has now been split into two different species, of which the southern taxon is '' S. occultus''), but it was split as a distinct species in a 2005 study. In 2021, a phylogenetic analysis confirmed its distinctiveness and found it to be the most basal member of the genus ''Scapanus''. This species inhabits the Sierra Juárez and San Pedro Mártir pine–oak forests ecoregion. Although its habitat is protected, large amounts of cattle Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joel Asaph Allen
Joel Asaph Allen (July 19, 1838 – August 29, 1921) was an American zoologist, mammalogist, and ornithologist. He became the first president of the American Ornithologists' Union, the first curator of birds and mammals at the American Museum of Natural History, and the first head of that museum's Department of Ornithology. He is remembered for Allen's rule, which states that the bodies of endotherms (warm-blooded animals) vary in shape with climate, having increased surface area in hot climates to lose heat, and minimized surface area in cold climates, to conserve heat. Early life Allen was born in Springfield, Massachusetts, the son of Joel Allen and Harriet Trumbull. He studied and collected specimen of natural history early in life, but he was forced to sell his relatively large collection so that he could attend the Wilbraham & Monson Academy in 1861. The following year, he transferred to Harvard University, where he studied under Louis Agassiz. Career as a field collecto ...

Broad-footed Mole in Baja California, Mexico
{{Animal common name ...
The broad-footed mole (''Scapanus latimanus'') was a former mole species that has since been split into three distinct species in the genus ''Scapanus'': * Northern broad-footed mole, ''Scapanus latimanus'', ranging from southern Oregon to central California. * Southern broad-footed mole, ''Scapanus occultus'', ranging from southern California to northernmost Baja California, Mexico * Mexican mole, ''Scapanus anthonyi'', found in a small portion of the Sierra de San Pedro Mártir Sierra de San Pedro Mártir ( Kiliwa: ʔxaal haq, en, mountains of Saint Peter the Martyr) is a mountain range located within southern Ensenada Municipality and southern Baja California state, of northwestern Mexico.

Endemic Fauna Of The Baja California Peninsula
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Mexico
This is a list of the native wild mammal species recorded in Mexico. As of September 2014, there were 536 mammalian species or subspecies listed. Based on IUCN data, Mexico has 23% more noncetacean mammal species than the U.S. and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors. Mexico's high mammal biodiversity is in part a reflection of the wide array of biomes present over its latitudinal, climatic and altitudinal ranges, from lowland tropical rainforest to temperate desert to montane forest to alpine tundra. The general increase in terrestrial biodiversity moving towards the equator is another important factor in the comparison. Mexico includes much of the Mesoamerican and Madrean pine-oak woodlands biodiversity hotspots. From a biogeographic standpoint, most of Mexico is linked to the rest of North America as part of the Nearctic realm. However, the lowlands of southern Mexico are linked with Central America and ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus ''Bos''. Adult females are referred to as cows and adult males are referred to as bulls. Cattle are commonly raised as livestock for meat ( beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather. They are used as riding animals and draft animals ( oxen or bullocks, which pull carts, plows and other implements). Another product of cattle is their dung, which can be used to create manure or fuel. In some regions, such as parts of India, cattle have significant religious significance. Cattle, mostly small breeds such as the Miniature Zebu, are also kept as pets. Different types of cattle are common to different geographic areas. Taurine cattle are found primarily in Europe and temperate areas of Asia, the Americas, and Australia. Zebus ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Juárez And San Pedro Mártir Pine–oak Forests
The Sierra Juárez and San Pedro Mártir pine–oak forests is a Nearctic temperate coniferous forests ecoregion that covers the higher elevations of the Sierra Juárez and Sierra San Pedro Mártir ranges of the Peninsular Ranges, of the northern Baja California Peninsula of Mexico. The pine–oak forests extend throughout the central portion of the Mexican state of Baja California and terminate near the border with the U.S. state of California. Setting The pine–oak forests cover an area of , bounded by the southern extent of the California chaparral and woodlands to the west, by the Baja California Desert to the southwest, and by the Sonoran Desert to the east. It lies at the southeastern extent of the Mediterranean climate region that covers much of California and the northwestern corner of Baja California, and the climate is temperate with winter rains. It is one of the southernmost ecoregions of the temperate coniferous forest biome in North America, and the only instanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapanus
''Scapanus'' is a genus of mole (animal), moles in the family Talpidae. They live in North America from west of the Rocky Mountains, Rockies south to Baja California, Baja California del Norte, and north to British Columbia, wherever conditions permit a mole population; that is to say, apart from the most sandy, rocky, or developed places. As they are one genus, they are very closely related, but as species, they rarely if ever interbreed successfully. It contains the following living species: * Mexican mole (''S. anthonyi'') *Northern broad-footed mole (''S. latimanus'') *Southern broad-footed mole (''S. occultus'') * Coast mole (''S. orarius'') * Townsend's mole (''S. townsendii'') In addition, there are several extinct species known from fossils. *''Scapanus hagermanensis'' (Blancan, Mid Blancan stage, Idaho) *''Scapanus malatinus'' (Blancan-Quaternary, California). *''Scapanus proceridens'' (Miocene, Oregon and Idaho) *''Scapanus shultzi'' (Miocene, California and Oregon) ...

Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and diversification. However, such a correlation does not make a given case predicable, so ancestral characters should not be imputed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapanus Occultus
The southern broad-footed mole (''Scapanus occultus'') is a species of mammal in the family Talpidae. It is found only in the U.S. state of California and northernmost Baja California in Mexico. Taxonomy It was formerly considered a subspecies of the northern broad-footed mole (''S. latimanus''), with the combined species being known as the broad-footed mole, but a 2021 study found sufficient anatomical and genetic divergence to split both as distinct species. The Mexican mole (''S. anthonyi'') was formerly thought to be a subspecies of the broad-footed mole but is now also considered a distinct species. Distribution It ranges from the throughout the southern Sierra Nevada and most of southern California from San Luis Obispo San Luis Obispo (; Spanish for " St. Louis the Bishop", ; Chumash: ''tiłhini'') is a city and county seat of San Luis Obispo County, in the U.S. state of California.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Epithet
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is cred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
