Southern Broad-footed Mole
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.

Joseph Grinnell
Joseph Grinnell (February 27, 1877 – May 29, 1939) was an American field biologist and zoologist. He made extensive studies of the fauna of California, and is credited with introducing a method of recording precise field observations known as the Grinnell System. He served as the first director of the Museum of Vertebrate Zoology at the University of California, Berkeley from the museum's inception in 1908 until his death. He edited '' The Condor'', a publication of the Cooper Ornithological Club, from 1906 to 1939, and authored many articles for scientific journals and ornithological magazines. He wrote several books, among them ''The Distribution of the Birds of California'' and ''Animal Life in the Yosemite''. He also developed and popularized the concept of the niche. Early years Joseph Grinnell was born February 27, 1877, the first of three children by his father Fordyce Grinnell MD and mother Sarah Elizabeth Pratt. Grinnell's father worked as the physician for the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fauna Of The Baja California Peninsula
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...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 International Union for Conservation of Nature, 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 Mesoamerica#Biodiversity, 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. Howeve ...

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 Townsend's mole is primarily a Cal ...

Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. 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 do not ...

Mexico–United States Border
The Mexico–United States border ( es, frontera Estados Unidos–México) is an international border separating Mexico and the United States, extending from the Pacific Ocean in the west to the Gulf of Mexico in the east. The border traverses a variety of terrains, ranging from urban areas to deserts. The Mexico–United States border is the most frequently crossed border in the world, with approximately 350 million documented crossings annually. It is the tenth-longest border between two countries in the world. The total length of the continental border is . From the Gulf of Mexico, it follows the course of the Rio Grande (Río Bravo del Norte) to the border crossing at Ciudad Juárez, Chihuahua, and El Paso, Texas. Westward from El Paso–Juárez, it crosses vast tracts of the Chihuahuan and Sonoran deserts to the Colorado River Delta and San Diego–Tijuana, before reaching the Pacific Ocean. Four American states border Mexico: California, Arizona, New Mexico, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sierra Nevada
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada.
