Eastern Fence Lizard
The eastern fence lizard (''Sceloporus undulatus'') is a medium-sized species of lizard in the Family (biology), family Phrynosomatidae. The species is found along forest edges, rock piles, and rotting logs or stumps in the eastern United States. It is sometimes referred to as the prairie lizard, fence swift, gray lizard, gravid lizard, northern fence lizard or pine lizard. It is also referred to colloquially as the horn-billed lizard. One of its most notable behaviors is that of its escape behavior when encountering fire ants. Taxonomy The Genus, generic name, ''Sceloporus'', is derived from the Ancient Greek, Greek ''skelos''/σκελος, meaning "leg", and the Latin ''porus'', meaning "hole", referring to the enlarged femoral pores found in this genus of lizards. The specific name, ''undulatus'', is Latin for "wave", referring to the transverse dark crossbars on the backs of these lizards.Henry Liddell, Liddell HG, Robert Scott (philologist), Scott R (1980).

Louis Augustin Guillaume Bosc
Louis Augustin Guillaume Bosc (or Louis-Augustin Bosc d'Antic) (29 January 1759 – 10 July 1828) was a French botanist, invertebrate zoologist, and entomologist. Biography Bosc was born in Paris, the son of Paul Bosc d’Antic, a medical doctor and chemist. He studied at Dijon, where he was the pupil of botanist Jean-François Durande and chemist Louis-Bernard Guyton-Morveau. Being unable to become an artilleryman, he worked initially for the office of the controller general and then for the comptroller of the postal service. In time he took courses in botany under Antoine-Laurent de Jussieu and met botanist René Desfontaines and naturalist Pierre Marie Auguste Broussonet. He also took up with Jean Marie Roland and Madame Roland and formed a lasting relationship with Danish entomologist Johan Christian Fabricius. While working for the postal service he carried out work on natural history, publishing a description of a new species of fly, Orthezia characais, and a method of pr ...

Femoral Pore
Femoral pores are a part of a holocrine secretory gland found on the inside of the thighs of certain lizards and amphisbaenians which releases pheromones to attract mates or mark territory. In certain species only the male has these pores and in other species, both sexes have them, with the male's being larger. Femoral pores appear as a series of pits or holes within a row of scales on the ventral portion of the animal's thigh. Femoral pores are present in all genera in the families Cordylidae, Crotaphytidae, Hoplocercidae, Iguanidae, Phrynosomatidae, and Xantusiidae. They are absent in all genera in the Anguidae, Chamaeleonidae, Dibamidae, Helodermatidae, Scincidae, Xenosauridae, and Varanidae families. They are present in other lizards and amphisbaenians quite variably, some geckoes, ''Phelsuma'', for example have these pores, others in the same family do not. In the desert iguana (''Dipsosaurus dorsalis''), the waxy lipids released from the femoral pores absorb ultravio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systematic Biology
Biological systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branches to further understand the relationshi ...

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Sceloporus Cowlesi
The southwestern fence lizard (''Sceloporus cowlesi''), also known as Cowles' prairie lizard, the White Sands prairie lizard or the White Sands swift, is species of spiny lizard in the family Iguanidae. The species is native to the Chihuahuan Desert of the south-western United States and north-central Mexico. Originally described in 1956 as ''Sceloporus undulatus cowlesi'', a subspecies of the eastern fence lizard, subsequent DNA studies elevated the southwestern fence lizard to species status. (''Sceloporus cowlesi'', new status). The following cladogram is based on Leaché and Reeder, 2002, and shows the relationship of ''Sceloporus cowlesi'' to other species in the "''Sceloporus undulatus'' group". Etymology The specific name, ''cowlesi'', is in honor of American herpetologist Raymond Bridgman Cowles Raymond Bridgman Cowles (pronounced "coals"; 1896–1975) was a herpetologist and professor at University of California, Los Angeles. Born in the British Colony of Natal (in wha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paraphyly
In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and most of its descendants, excluding a few monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia ( reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor, including all extant reptiles as well as the extinct synapsids, ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
