Incilius Praevius
''Incilius'' is a 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 ...

Early Miocene
The Early Miocene (also known as Lower Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages: the Aquitanian age, Aquitanian and Burdigalian stages. The sub-epoch lasted from 23.03 ± 0.05 annum, Ma to 15.97 ± 0.05 Ma (million years ago). It was preceded by the Oligocene epoch. As the climate started to get cooler, the landscape started to change. New mammals evolved to replace the extinct animals of the Oligocene epoch. The first members of the hyena and weasel family started to evolve to replace the extinct ''Hyaenodon'', entelodonts and bear-dogs. The chalicotheres survived the Oligocene epoch. A new genus of entelodont called ''Daeodon'' evolved in order to adapt to the new habitats and hunt the new prey animals of the Early Miocene epoch; it quickly became the top predator of North America. But it became extinct due to competition from ''Amphicyon'', a newcomer from Eurasia. ''Amphicyon'' bested ''Daeodon'' because the bear-dog's la ...

Splitter (taxonomy)
Lumpers and splitters are opposing factions in any academic discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example, schools of literature, biological taxa, and so on. A "lumper" is a person who assigns examples broadly, judging that differences are not as important as signature similarities. A "splitter" makes precise definitions, and creates new categories to classify samples that differ in key ways. Origin of the terms The earliest known use of these terms was thought to be Charles Darwin, in a letter to Joseph Dalton Hooker in 1857: "It is good to have hair-splitters & lumpers". But according to research done by the deputy director at NCSE, Glenn Branch, the credit is due to naturalist Edward Newman who wrote in 1845, "The time has arrived for discarding imaginary species, and the duty of doing this is as imperative a ...

Incilius Chompipe
''Incilius chompipe'' is a species of toads in the family Bufonidae, known from several localities near Cascajal in the Cerro Chompipe and in the Reserva Dantas, both in the Cordillera Central of Costa Rica. Description Males measure and females, based on a single specimen, in snout–vent length. The body is robust. The head bears canthal, supraorbital, supratympanic, and parietal crests, and the snout is acutely pointed. Parotoid glands are triangular and barely evident.

Incilius Aucoinae
''Incilius aucoinae'' is a species of toads in the family Bufonidae. It is found in south-western Costa Rica and adjacent western Panama.

Incilius Alvarius
The Colorado River toad (''Incilius alvarius''), also known as the Sonoran Desert toad, is a toad species found in northwestern Mexico and the southwestern United States. It is well known for its ability to exude toxins from glands within its skin that have psychoactive properties. Description The Colorado River toad can grow to about long and is the largest toad in the United States apart from the non-native cane toad (''Rhinella marina''). It has a smooth, leathery skin and is olive green or mottled brown in color. Just behind the large golden eye with horizontal pupil is a bulging kidney-shaped parotoid gland. Below this is a large circular pale green area which is the tympanum or ear drum. By the corner of the mouth there is a white wart and there are white glands on the legs. All these glands produce toxic secretions. Its call is described as, "a weak, low-pitched toot, lasting less than a second." Dogs (''Canis familiaris'') that have attacked toads have suffered paralys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subgenus
In biology, a subgenus ( subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all tho ... (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darrel Frost
Darrel Richmond Frost (born 1951) is an American Herpetology, herpetologist and systematist. He was previously head curator of herpetology at the American Museum of Natural History, as well as president of both the Society for the Study of Amphibians and Reptiles (1998) and the American Society of Ichthyologists and Herpetologists (2006). Four taxa are named in his honor: the toad genus ''Frostius'' (which includes Frostius pernambucensis, Frost's Toad), the tree frog ''Dendropsophus, Dendropsophus frosti'', Darrel's Chorus Frog ''Microhyla darreli'', and Frost's arboreal alligator lizard ''Abronia frosti''. Life Frost became interested in animals after witnessing his father kill a rattlesnake at the age of four. He earned a B.S. in biology from the University of Arizona in 1973, an M.S. in zoology from Louisiana State University in 1978, and a Ph.D. in ecology and systematics from the University of Kansas in 1988. He became an adjunct professor at Columbia University in 2000. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anaxyrus
''Anaxyrus'', containing the North American toads, is a genus of true toads in the family Bufonidae. The genus is endemic to North and Central America, and contains many familiar North American toad species such as the American toad, Woodhouse's toad, and the western toad. Most species in this genus were initially classified in ''Bufo'', but were split due to their genetic divergence and geographic separation. Some authorities still consider ''Anaxyrus'' to be a subgenus within ''Bufo''. However, other authorities have disputed this classification, as doing so would also require all morphologically distinct Old World toad species to also be placed in ''Bufo''. Species The following fossil taxa are also known, all of which were also previously placed in ''Bufo'': * †'' Anaxyrus defensor'' (Meylan, 2005) (Pliocene/early Pleistocene of Florida) * †'' Anaxyrus hibbardi'' (Taylor, 1937) (Late Miocene of Kansas) * †'' Anaxyrus pliocompactilis'' (Wilson, 1968) (Late Miocene of K ...
