Bothrops Erythromelas
''Bothrops erythromelas'', commonly known as the Caatinga lancehead or the ''jararaca-da-seca'', is a species of venomous snake in the family Viperidae.McDiarmid RW, Campbell JA, Touré T. 1999. ''Snake Species of the World: A Taxonomic and Geographic Reference, Volume 1''. Herpetologists' League. 511 pp. (series). (volume). It is endemic to Brazil. Etymology The specific name, ''erythromelas'', is from the Ancient Greek words έρυθρός ''(érythrós)'', meaning "red", and μέλας ''(mélas)'', meaning "black", referring to this snakes coloration. Geographic range It is found in the Brazilian states of Alagoas, Bahia, Ceará Ceará (, pronounced locally as or ) is one of the 26 states of Brazil, located in the northeastern part of the country, on the Atlantic coast.

Pernambuco
Pernambuco () is a state of Brazil, located in the Northeast region of the country. With an estimated population of 9.6 million people as of 2020, making it seventh-most populous state of Brazil and with around 98,148 km², being the 19th-largest in area among federative units of the country, it is the sixth-most densely populated with around 89 people per km². Its capital and largest city, Recife, is one of the most important economic and urban hubs in the country. Based on 2019 estimates, the Recife Metropolitan Region is seventh-most populous in the country, and the second-largest in northeastern Brazil. In 2015, the state had 4.6% of the national population and produced 2.8% of the national gross domestic product (GDP). The contemporary state inherits its name from the Captaincy of Pernambuco, established in 1534. The region was originally inhabited by Tupi-Guarani-speaking peoples. European colonization began in the 16th century, under mostly Portuguese rule in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bothrops
''Bothrops'' is a genus of highly venomous pit vipers endemic to Central and South America.McDiarmid RW, Campbell JA, Touré T. 1999. ''Snake Species of the World: A Taxonomic and Geographic Reference, vol. 1''. Herpetologists' League. 511 pp. (series). (volume). The generic name, ''Bothrops'', is derived from the Greek words βόθρος, ''bothros'', meaning "pit", and ώπς, ''ops'', meaning "eye" or "face", together an allusion to the heat-sensitive loreal pit organs. Members of this genus are responsible for more human deaths in the Americas than any other group of venomous snakes.Campbell JA, Lamar WW. 2004. ''The Venomous Reptiles of the Western Hemisphere''. Comstock Publishing Associates, Ithaca and London. 870 pp. 1500 plates. . Currently, 48 species are recognized. Description These snakes range from small, never growing to more than , to large at over in total length. Most are characterized by having a sharp ''canthus rostralis'' and an unelevated snout.

Afrânio Pompílio Gastos Do Amaral
Afrânio Pompílio Gastos do Amaral (1 December 1894 in Belém – 29 November 1982 in São Paulo) was a Brazilian herpetologist. As a youngster, he collected snakes for Augusto Emilio Goeldi (1859-1917). He studied medicine in Salvador, Bahia, later finding employment at the Instituto Butantan in São Paulo. Here, his work involved research and production of anti-venom serum. In 1921 he succeeded Vital Brazil (1865-1950) as director of the Instituto Butantan. During his career, he was the author of over 450 published works.Paragraph based on translated text of an equivalent article at the French Wikipedia; source listed as: Kraig Adler (1989).

Thorn Forest
A thorn forest is a dense scrubland with vegetation characteristic of dry subtropical and warm temperate areas with a seasonal rainfall averaging . Regions Africa Is present in the southwest of Africa Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area ... with smaller areas in other places of Africa. * Thornveld often referred to as "acacia thornveld" * Madagascar spiny forests North America Thorn forests cover a large part of southwestern North America. * Pinyon–juniper woodland in Utah and the Canyonlands region. South America In South America, the thorn forest is sometimes called ''Caatinga'', and consists primarily of small, thorny trees that shed their leaves seasonally. Trees typically do not exceed in height, usually averaging between tall. Caatinga is considered a xeric s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi, become quite cold in winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water.

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caatinga
Caatinga (, ) is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" is a Tupi word meaning "white forest" or "white vegetation" (''caa'' = forest, vegetation, ''tinga'' = white). The Caatinga is a xeric shrubland and thorn forest, which consists primarily of small, thorny trees that shed their leaves seasonally. Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month long rainy season. Caatinga falls entirely within earth's tropical zone and is one of 6 major ecoregions of Brazil. It covers 850,000 km², nearly 10% of Brazil's territory. It is home to 26 million people and over 2000 species of plants, fish, reptiles, amphibians, birds, and mammals. The Caatinga is the only exclusively Brazilian biome, which means that a large part of its biological heritage cannot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Sergipe
Sergipe (), officially State of Sergipe, is a state of Brazil. Located in the Northeast Region along the Atlantic coast of the country, Sergipe is the smallest state in Brazil by geographical area at , larger only than the Federal District. Sergipe borders Bahia to the south and west and Alagoas to the north. Aracaju is the capital and the largest city in the state; the state is divided into 75 municipalities. The state has 1.1% of the Brazilian population and produces only 0.6% of the Brazilian GDP. Geography As with most of the states in northeastern Brazil, inland Sergipe is almost entirely savanna (''caatinga''), and its coastline is characterized by mangroves, swamps and sandy beaches. A small strip of tropical rainforest runs down the coast. The São Francisco River forms its northern boundary, and the drainage of the northern part of the state is northward and eastward to that river. The southern half of the state slopes eastward and is drained directly into the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
