Pseudoeurycea Mixcoatl
''Pseudoeurycea mixcoatl'', commonly known as brown-streaked salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico. It is native to the Sierra Madre del Sur of Guerrero state, around the towns of Asoleadero and Carrizal de Bravo. It occurs at elevations ranging between 2,200 and 2,600 meters elevation. Its current known extent of occurrence (EOO) is 50 km2. Its natural habitat is oak-pine-fir cloud forest dominated by large bromeliad-covered oaks. It takes daytime refuge in fallen logs. It is threatened by habitat loss. The species' specific descriptor is named after Mixcoatl, a pre-Columbian deity figure among a number of central Mexican cultures such as the Otomi and Nahua. The Classical Nahuatl Classical Nahuatl (also known simply as Aztec or Nahuatl) is any of the variants of Nahuatl spoken in the Valley of Mexico and central Mexico as a ''lingua franca'' at the time of the 16th-century Spanish conquest of the Aztec Empire.

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 lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixcoatl
Mixcoatl ( nah, Mixcōhuātl}, from mixtli "cloud" and cōātl "serpent"), or Camaxtle or Camaxtli, was the god of the hunt and identified with the Milky Way, the stars, and the heavens in several Mesoamerican cultures. He was the patron deity of the Otomi, the Chichimecs, and several groups that claimed descent from the Chichimecs. Under the name of Camaxtli, Mixcoatl was worshipped as the central deity of Huejotzingo and Tlaxcala. Representation Mixcoatl is represented with a black mask over his eyes and distinctive red and white pin stripes painted on his body. These features are shared with Tlahuizcalpanteuctli, the Lord of the Dawn, god of the morning star, as well as Itzpapalotl, goddess of infant mortality who was sometimes said to be his mother. Unlike Tlahuizcalpanteuctli, Mixcoatl can usually be distinguished by his hunting gear, which included a bow and arrows, and a net or basket for carrying dead game. Mythology Mixcoatl was one of four children of Tonacatecut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Sierra Madre Del Sur
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] |
Endemic Amphibians Of Mexico
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoeurycea
''Pseudoeurycea'' is a genus of salamander in the family Plethodontidae. The members of this genus are commonly known as the false brook salamanders. They are found in Mexico and Guatemala. In order to preserve ''Ixalotriton'' and ''Bolitoglossa'' while avoiding paraphyly of ''Pseudoeurycea'', species in the former "''Pseudoeurycea bellii'' species group" have been moved to the genus ''Isthmura'', and those in the former "''Pseudoeurycea cephalica'' species group" to ''Aquiloeurycea''.

Classical Nahuatl
Classical Nahuatl (also known simply as Aztec or Nahuatl) is any of the variants of Nahuatl spoken in the Valley of Mexico and central Mexico as a ''lingua franca'' at the time of the 16th-century Spanish conquest of the Aztec Empire. During the subsequent centuries, it was largely displaced by Spanish and evolved into some of the modern Nahuan languages in use today (other modern dialects descend more directly from other 16th-century variants). Although classified as an extinct language, Classical Nahuatl has survived through a multitude of written sources transcribed by Nahua peoples and Spaniards in the Latin script. Classification Classical Nahuatl is one of the Nahuan languages within the Uto-Aztecan family. It is classified as a central dialect and is most closely related to the modern dialects of Nahuatl spoken in the valley of Mexico in colonial and modern times. It is probable that the Classical Nahuatl documented by 16th- and 17th-century written sources represents a par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nahua Peoples
The Nahuas () are a group of the indigenous people of Mexico, El Salvador, Guatemala, Honduras, and Nicaragua. They comprise the largest indigenous group in Mexico and second largest in El Salvador. The Mexica (Aztecs) were of Nahua ethnicity, and the Toltecs are often thought to have been as well, though in the pre-Columbian period Nahuas were subdivided into many groups that did not necessarily share a common identity. Their Nahuan languages, or Nahuatl, consist of many variants, several of which are mutually unintelligible. About 1.5 million Nahuas speak Nahuatl and another million speak only Spanish. Fewer than 1,000 native speakers of Nahuatl remain in El Salvador. It is suggested that the Nahua peoples originated near Aridoamerica, in regions of the present day Mexican states of Durango and Nayarit or the Bajío region. They split off from the other Uto-Aztecan speaking peoples and migrated into central Mexico around 500 CE. The Nahua then settled in and around the Basin ...

Otomi People
The Otomi (; es, Otomí ) are an indigenous people of Mexico inhabiting the central Mexican Plateau (Altiplano) region. The Otomi are an indigenous people of Mexico who inhabit a discontinuous territory in central Mexico. They are linguistically related to the rest of the Otomanguean-speaking peoples, whose ancestors have occupied the Trans-Mexican Volcanic Belt since several millennia before the Christian era. Currently, the Otomi inhabit a fragmented territory ranging from northern Guanajuato, to eastern Michoacán and southeastern Tlaxcala. However, most of them are concentrated in the states of Hidalgo, Mexico and Querétaro. According to the National Institute of Indigenous Peoples of Mexico, the Otomi ethnic group totaled 667,038 people in the Mexican Republic in 2015, making them the fifth largest indigenous people in the country. Of these, only a little more than half spoke Otomi. In this regard, it should be said that the Otomi language presents a high degree of interna ...

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, introdu ...

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] |
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, ''Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss (''Tillandsia usneoides''), and terrestrial species, such as the pineapple (''Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species that gath ...
