Holdridge's Toad
Holdridge's toad (''Incilius holdridgei'', formerly ''Bufo holdridgei'') is a species of toad endemic to Costa Rica. In October 2008, it was declared extinct by the International Union for Conservation of Nature in its Red List since the species had not been seen since 1987, despite years of extensive searches. However, the species was rediscovered in 2010 by a Costa Rican herpetologist and is now classified as critically endangered. It is believed that the species is most threatened by the presence of the chytrid fungus in its habitat.Incilius holdridgei AmphibiaWeb (4 October 2011). Retrieved on 2013-01-01.

Edward Harrison Taylor
Edward Harrison Taylor (April 23, 1889 – June 16, 1978) was an American herpetologist from Missouri. Family Taylor was born in Maysville, Missouri, to George and Loretta Taylor. He had an older brother, Eugene. Education Taylor studied at the University of Kansas in Lawrence, Kansas, graduating with a B.A. in 1912. Field trips during his time at the University of Kansas with Dr. Clarence McClung and Dr. Roy Moody helped prepare Taylor for his future endeavors. Between 1916 and 1920 he returned briefly to Kansas to finish his M.A. Career Upon completing his bachelor's degree, Taylor went to the Philippines, where at first he held a teacher's post in a village in central Mindanao. He collected and studied the local herpetofauna extensively and published many papers. He returned to the Philippines after completing his master's degree and was appointed Chief of Fisheries in Manila. On his many survey trips he continued collecting and studying fishes and reptiles of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incilius Fastidiosus
''Incilius fastidiosus'', or the Pico Blanco toad, is a species of toad from western Panama and southeastern Costa Rica. It inhabits premontane and lower montane rainforest. It is largely a fossorial species that breeds explosively in temporary pools after heavy rains in late April–May. Juveniles occur on rocky stream margins the year round. It is listed as a critically endangered species due to a drastic population decline, probably caused by chytridiomycosis, and to some extent, 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 ....

Endemic Fauna Of Costa Rica
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] |
Incilius
''Incilius'' is genus of toads in the true toad family, Bufonidae. They are sometimes known as the Central American toads or Middle American toads and are found in southern USA, Mexico, Central America, and northern Pacific South America (Colombia and Ecuador). They are an ecologically and biogeographically diverse group of toads, including micro-endemic species such as ''Incilius spiculatus'' that are restricted to undisturbed cloud forests, and widespread lowland species such as ''Incilius valliceps'' that predominantly occur in disturbed habitats. Taxonomy and systematics This genus was first described in 1863 by Edward Drinker Cope who designated the type species as '' Incilius coniferus''. This proved unpopular and these toads were known under the genus ''Bufo'' until the early 2000s. The current delineation of the genus follows Mendelson ''et al''. (2011) who brought ''Cranopsis''/''Cranophryne''/''Ollotis'' and ''Crepidius''/''Crepidophryne'' into synonymy with ''Inciliu ...

Chytridiomycosis
Chytridiomycosis ( ) is an infectious disease in amphibians, caused by the chytrid fungi '' Batrachochytrium dendrobatidis'' and '' Batrachochytrium salamandrivorans''. Chytridiomycosis has been linked to dramatic population declines or extinctions of amphibian species in western North America, Central America, South America, eastern Australia, east Africa (Tanzania), and Dominica and Montserrat in the Caribbean. Much of the New World is also at risk of the disease arriving within the coming years. The fungus is capable of causing sporadic deaths in some amphibian populations and 100% mortality in others. No effective measure is known for control of the disease in wild populations. Various clinical signs are seen by individuals affected by the disease. A number of options are possible for controlling this disease-causing fungus, though none has proved to be feasible on a large scale. The disease has been proposed as a contributing factor to a global decline in amphibi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossorial
A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many prehistoric phyla and taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include '' Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineage which includes modern mammals and their ancestors, is a cynodont, '' Thrinaxodon liorhinus'', found in the Karoo of South Africa, estimated to be 251 million years old.

Parotoid Gland
The parotoid gland (alternatively, paratoid gland) is an external skin gland on the back, neck, and shoulder of toads and some frogs and salamanders. It can secrete a number of milky alkaloid substances (depending on the species) known collectively as bufotoxins, which act as neurotoxins to deter predation. These cutaneous glands are called parotoid as they are somewhat similarly positioned to mammalian parotid gland, although the latter have a different function, excreting saliva within the mouth rather than externally excreted defensive chemicals. A study of the parotoid glands of the Colorado River toad in 1976 found that the parotoid glands were "composed of numerous lobules", each of which is a separate unit with a lumen surrounded by a double cell layer. The cell layers have interlocking microvilli. The study found that the outer cell layer resembled smooth muscle cells, with some organelles hypothesised to "function in some aspects of venom synthesis, active cellular ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of ana ...

Incilius Peripetates
The Almirante Trail toad (''Incilius peripatetes'') is a species of toad endemic to Panama. It is only known from its type locality near Boquete, Chiriquí, in western Panama. Another population from Cerro Bollo that has been referred to this species was described in 2013 as a separate species, '' Incilius majordomus''. Etymology The specific name ''peripatetes'' is Greek for "one who walks" and alludes to Charles F. Walker, a student of herpetology at the University of Michigan. Description ''Incilius peripatetes'' is a medium-sized toad, with the holotype, an adult male, reported to be in snout–vent length. Dorsal coloration is uniformly light brown or grey. The dorsum is rugose, without enlarged warts. The cranial crests are very prominent, whereas the paratoid glands are slightly small, smaller than the eye. The ventral surface is light brown. The rear surfaces of the thighs and the groin are dark brown or black, with some light spots in the groin. The hands and feet h ...

Cordillera Central (Costa Rica)
The Cordillera Central is a volcanic mountain range in central Costa Rica which continues from the Continental Divide to east of Cordillera de Tilarán. It extends 80 km from Tapezco Pass to the Turrialba Volcano and ending on the Pacuare River. It is separated from Cordillera de Tilarán by Balsa River and Platanar and Zarcero hills. The Cordillera Central is part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica. It contains four large volcanoes Poás (2,708 m), Barva (2,906 m), Irazú and Turrialba (3,340 m). The highest peak is Irazú at 3,432 m. South of the range lie elevated plains of central tectonic depression of Costa Rican Central Valley. Cordillera Central's four main volcanoes are protected as national parks. Volcanic massif of the Poás Volcano is the central feature of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toad
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture ( folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae (fire-bellied toads and jungle toads) * Calyptocephalellidae ( helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae ( European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae ( American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps ...
