El Tepozteco National Park
El Tepozteco National Park is a national park in Morelos state of central Mexico. It protects 232.59 km2 in the mountains of the Trans-Mexican Volcanic Belt. The park includes El Tepozteco, an archeological site featuring an Aztec temple. Geography El Tepozteco National Park covers the central portion of the Sierra Chichinautzin, a volcanic field which separates the Valley of Mexico to the north from the Balsas Basin to the south. Chichinautzin Volcano (3490 m), the highest peak in the park, is at the park's northwest corner. The Sierra de Tepoztlán is closer to the center of the park, immediately north of the town of Tepoztlán. The terrain is mostly steep, ranging from 1200 to 3480 meters elevation. The volcanic field is relatively recent – Chichinautzin Volcano's last major eruption was approximately 1800 years ago – and the park's landscape includes cinder cones and lava flows.Siebe, Claus & Macías, J..

Morelos
Morelos (), officially the Free and Sovereign State of Morelos ( es, Estado Libre y Soberano de Morelos), is one of the 32 states which comprise the Federal Entities of Mexico. It is divided into 36 municipalities and its capital city is Cuernavaca. Morelos is a landlocked state located in South Central Mexico. It is bordered by Mexico City to the north, and by the states of México to the northeast and northwest, Puebla to the east and Guerrero to the southwest. Morelos is the second-smallest state in the nation, just after Tlaxcala. It was part of a very large province, the State of Mexico, until 1869 when Benito Juárez decreed that its territory would be separated and named in honor of José María Morelos y Pavón, who defended the city of Cuautla from royalist forces during the Mexican War of Independence. Most of the state enjoys a warm climate year-round, which is good for the raising of sugar cane and other crops. Morelos has attracted visitors from the Valley of ...

Dusky Hummingbird
The dusky hummingbird (''Phaeoptila sordida'') is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to Mexico. Taxonomy and systematics The dusky hummingbird was formerly placed in the genus '' Cynanthus''. Based on a molecular phylogenetic study published in 2014 and a 2017 publication, the North American Classification Committee of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy moved it to the resurrected genus ''Phaeoptila'' that had been introduced in 1861 by John Gould.Clements, J.

Dwarf Mexican Tree Frog
The dwarf Mexican tree frog (''Tlalocohyla smithii'') is a species of frog in the family Hylidae endemic to Mexico. Habitat and distribution Its natural habitats are subtropical or tropical dry forests, intermittent river A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of wate ...s, and intermittent freshwater marshes. It ranges from central Sinaloa southwards along the Pacific lowlands to southern Oaxaca, and inland in the Balsas-Tepalcatepec Basin Guerrero, Morelos, and Puebla states. It is found at elevations from sea level to 1,332 meters. Conservation It is threatened by habitat loss.The frog's distribution is caused by abiotic and biotic factors as well as, the availability of resources and characteristics of reproductive sites.

Mexican Beaded Lizard
The Mexican beaded lizard (''Heloderma horridum'') is a species of lizard in the family Helodermatidae The Helodermatidae or beaded lizards are a small family of lizards endemic to North America today, but formerly more widespread in the ancient past. Traditionally, the Gila monster and the Mexican beaded lizard were the only species recognized, ..., one of the two species of venomous beaded lizards found principally in Mexico and southern Guatemala. It and congener (biology), the other member of the same genus, the Gila monster (''Heloderma suspectum''), are the only lizards known to have evolved an overt venom delivery system. The Mexican beaded lizard is larger than the Gila monster, with duller coloration, black with yellowish bands. As it is a specialized predator that feeds primarily upon eggs, the primary use of its venom is still a source of debate among scientists. This venom has been found to contain several enzymes useful for manufacturing drugs in the treatment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Sierra Madre Sparrow
The Sierra Madre sparrow (''Xenospiza baileyi''), also known as Bailey's sparrow, is an endangered, range-restricted, enigmatic American sparrow. It is endemic to Mexico and is threatened with extinction through habitat loss. Etymology The genus name ''Xenospiza'' is from the Ancient Greek '' xénos'' (ξένος), "a stranger", and ''spíza'' (σπίζα), "finch". The species name ''baileyi'' is a dedication to Alfred M. Bailey, who collected the 1931 specimen for Outram Bangs. History and taxonomy The Sierra Madre sparrow was first discovered by scientists in the Sierra de Bolaños near Bolaños, Jalisco, in 1889. The eight specimens shot then were not recognized as what they were, but believed to be aberrant Savannah or Mexican Plateau song sparrows, or hybrids. Only when another bird was taken near the city of Durango in 1931 was it recognized as a valid and distinct species. The southern population was discovered only in 1945, but has been observed since then in sev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
