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, bovid ungulates widely kept as livestock. They are prominent modern members of the subfamily Bovinae and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joel Asaph Allen
Joel Asaph Allen (July 19, 1838 – August 29, 1921) was an American zoology, zoologist, mammalogy, mammalogist, and ornithology, 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 Agassi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broad-footed Mole
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 Mexico, officially the United Mexican States, is a country in North America. It is the northernmost country in Latin America, and borders the United States to the north, and Guatemala and Belize to the southeast; while having maritime boundar ... * Mexican mole, ''Scapanus anthonyi'', found in a small portion of the Sierra de San Pedro Mártir in Baja California, Mexico {{Animal common name ...

Endemic Fauna Of The Baja California Peninsula
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, bovid ungulates widely kept as livestock. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus '' Bos''. Mature female cattle are called cows and mature male cattle are bulls. Young female cattle are called heifers, young male cattle are oxen or bullocks, and castrated male cattle are known as steers. Cattle are commonly raised for meat, for dairy products, and for leather. As draft animals, they pull carts and farm implements. Cattle are considered sacred animals within Hinduism, and it is illegal to kill them in some Indian states. Small breeds such as the miniature Zebu are kept as pets. Taurine cattle are widely distributed across Europe and temperate areas of Asia, the Americas, and Australia. Zebus are found mainly in India and tropical areas of Asia, America, and Australia. Sanga cattle are found primarily in sub-Saharan Africa. These types, sometime ... [...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 instance ...

Scapanus
''Scapanus'' is a genus of moles in the family Talpidae. They live in North America from west of the Rockies south to 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'' ( Mid Blancan stage, Idaho) *''Scapanus malatinus'' (Blancan-Quaternary, California). *''Scapanus proceridens'' (Miocene, Oregon and Idaho) *''Scapanus shultzi'' (Miocene, California and Oregon) Distribution Broad-footed mole's are primarily C ...

Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a phylogenetic tree#Rooted tree, 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, Phylogenetic diversity, 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 cladogenesis, diversification. However, such a correlation does not make a given ca ...

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 south to the U.S.-Mexico border, and along the Peninsular Ranges into northernmost Baja California. In the two areas where ''S. occultus'' and ''S. latimanus'' are sympatric In biology, two closely related species or populations are considered sympat ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Epithet
In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called 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 grammar, Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the ''generic name (biology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
