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] |
Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating los ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plethodontidae
Plethodontidae, or lungless salamanders, are a family of salamanders. Most species are native to the Western Hemisphere, from British Columbia to Brazil, although a few species are found in Sardinia, Europe south of the Alps, and South Korea. In terms of number of species, they are by far the largest group of salamanders. Biology Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature adults. Direct development is correlated with changes in the developmental characteristics of plethodontids compared to other families of salamanders including increases in egg size and duration of embryonic development. Additionally, the evolutionary loss of the aquatic larval stage is related to a diminishing dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Madre Oriental Pine–oak Forests
The Sierra Madre Oriental pine–oak forests are a Temperate broadleaf and mixed forests ecoregion of northeastern and Central Mexico, extending into the state of Texas in the United States. Setting The Sierra Madre Oriental pine–oak forests are found at elevations of above sea level in the Sierra Madre Oriental range, which runs north and south between the Gulf Coastal Plain to the east along the Gulf of Mexico, and the Mexican Plateau to the west. They are also found in the Sierra Norte de Puebla, adjacent to the southern Sierra Madre Oriental. The ecoregion covers an area of . The southernmost forests transition to the Trans-Mexican Volcanic Belt pine–oak forests in central Puebla state, near the southern end of the Sierra Madre Oriental. The forests extend almost continuously along the range through the states of Veracruz, Hidalgo, Querétaro, Guanajuato, San Luis Potosí, Tamaulipas, Nuevo León, and northern Puebla. North of Monterrey, the forests become discontinuous, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hidalgo (state)
Hidalgo (), officially the Free and Sovereign State of Hidalgo ( es, Estado Libre y Soberano de Hidalgo) is one of the 31 states which, along with Mexico City, constitute the 32 federal entities of Mexico. It is divided into 84 municipalities and its capital city is Pachuca de Soto. Located in the eastern part of the country, Hidalgo is bordered by San Luis Potosí and Veracruz on the north, Puebla on the east, Tlaxcala and State of Mexico on the south and Querétaro on the west. In 1869, Benito Juárez created the State of Hidalgo and made Pachuca its capital city; Juárez would add the name ''"de Soto"'' in recognition of Manuel Fernando Soto, who is considered the most important driving force in creating the state. The state was named after Miguel Hidalgo y Costilla, the initiator of the Mexican War of Independence. The indigenous peoples of the state, such as the Otomi, retain much of their traditional culture. In addition to Mexicans of Spanish descent, there are also ...

Chiropterotriton
''Chiropterotriton'', also known as splayfoot salamanders or flat-footed salamanders, is a genus of salamanders in the family Plethodontidae. The genus is endemic to Mexico. ''Chiropterotriton'' are widely distributed in northern and eastern Mexico. They are an ecologically diverse group, occupying a range of habitats, including cloud forests, pine-oak forests, oak forests, and caves. They may be found in various microhabitats, such as arboreal bromeliad The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, ...s, rock crevices, caves, and terrestrial cover objects.

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a ...

Cave Salamanders
A cave salamander is a type of salamander that primarily or exclusively inhabits caves, a group that includes several species. Some of these animals have developed special, even extreme, adaptations to their subterranean environments. Some species have only rudimentary (or even absent) eyes (''blind salamanders''). Others lack pigmentation, rendering them a pale yellowish or pinkish color (e.g., '' Eurycea rathbuni''). With the notable exception of '' Proteus anguinus'', all "cave salamanders" are members of the family Plethodontidae ("lungless salamanders"). History The first dedicated scientific study of a cave animal was focused upon a cave salamander, '' Proteus anguinus''. It was originally identified as a "dragon's larva" by Johann Weikhard von Valvasor in 1689. Later, the Austrian naturalist Joseph Nicolaus Lorenz described it scientifically in 1768. Another early scientific description of a cave salamander was undertaken by Constantine Samuel Rafinesque in 1822 while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
