Plestiodon Callicephalus
''Plestiodon callicephalus'', commonly known as the mountain skink, is a species of lizard, a medium-sized member of the ''Plestiodon'' skinks, endemic to North America. Taxonomy At least one herpetologist has considered this species to be a subspecies of '' Plestiodon tetragrammus'' under the scientific name ''P. tetragrammus callicephalus'', but the more common classification considers it to be a separate species based on differences in appearance and its distinct geographic distribution. Description The mountain skink is a medium-sized skink reaching a maximum length from snout to vent of about . Its body is olive to brown in color, with black stripes on the sides. On the head, it features a distinctive, roughly Y-shaped light line pattern, which gave rise to its scientific name: ''callicephalus'' is Greek and means "beautiful head". Like many other ''Plestiodon'', juvenile mountain skinks have a bright blue tail. However, contrary to most other species of this genus, adu ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

Jalisco
Jalisco, officially the Free and Sovereign State of Jalisco, is one of the 31 states which, along with Mexico City, comprise the 32 Political divisions of Mexico, Federal Entities of Mexico. It is located in western Mexico and is bordered by six states, Nayarit, Zacatecas, Aguascalientes, Guanajuato, Michoacán, and Colima. Jalisco is divided into Municipalities of Jalisco, 125 municipalities, and its capital and largest city is Guadalajara. Jalisco is one of the most economically and culturally important states in Mexico, owing to its natural resources as well as its long history and culture. Many of the characteristic traits of Mexican culture are originally from Jalisco, such as mariachi, tequila, ranchera, ranchera music, birria, jaripeo, etc., hence the state's motto: ('Jalisco is Mexico'). Economically, it is ranked third in the country, with industries centered in the Guadalajara metropolitan area, the third largest metropolitan area in Mexico. The state is home to two ...

Reptiles Of Mexico
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting Taxonomy, taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the Class (biology), class Reptilia ( ), which corresponds to common usage. Modern Cladistics, cladistic taxonomy regards that group as Paraphyly, paraphyletic, since Genetics, genetic and Paleontology, paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among re ...

Hobart Muir Smith
Hobart Muir Smith, born Frederick William Stouffer (September 26, 1912 – March 4, 2013), was an Americans, American Herpetology, herpetologist. He is credited with describing more than 100 new species of American reptiles and amphibians. In addition, he has been honored by having at least six species named after him, including the southwestern blackhead snake (''Tantilla hobartsmithi)'', Smith's earth snake (''Uropeltis grandis''), Smith's arboreal alligator lizard (''Abronia smithi)'', Hobart's anadia (''Anadia hobarti)'', Hobart Smith's anole (''Anolis hobartsmithi)'', and Smith's rose-bellied lizard (''Sceloporus smithi)''. At 100 years of age, Smith continued to be an active and productive herpetologist. Although he published on a wide range of herpetological subjects, his main focus throughout his career was on the amphibians and reptiles of Mexico, including taxonomy, bibliographies, and history. Having published more than 1,600 manuscripts, he surpassed all contempor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes.

Invertebrate
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a ''spine'' or ''backbone''), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordata, chordate subphylum Vertebrata, i.e. vertebrates. Well-known Phylum, phyla of invertebrates include arthropods, molluscs, annelids, echinoderms, flatworms, cnidarians, and sponges. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxon, taxa have a greater number and diversity of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 10 Micrometre, μm (0.0004 in) myxozoans to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are actually sister chordate subphyla to Vertebrata, being more closely related to vertebrates than to other invertebrates. This makes the "invertebrates" para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall, or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that has fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O-horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is m ...
