Xenohyla Eugenioi
''Xenohyla eugenioi'' is a species of tree frog in the Hylidae family native to northeastern Brazil in ecotones between the Atlantic Forest and caatingas. It has been found in the Brazilian states of Bahia and Sergipe, approximately 1,000 km away from the other species in its genus, ''Xenohyla truncata''. Like its relative, this frog spends the day hiding in bromeliads, emerging at night to hunt and forage. ''X. eugenioi'' keeps its white stripes through adulthood. Additionally, the species prefers to inhabit agrestes, and breeds in temporary pools formed by rainwater. Males grow from 30.9 to 31.5 mm (1.22 to 1.24 in) SVL while females reach 39.5 to 45.5 mm (1.56 to 1.8 in) SVL. It is currently unknown if this frog is also frugivorous like its relative. ''Xenohyla eugenioi'' is named after the Brazilian herpetologist Eugênio Izecksohn. Izecksohn described the type species '' Hyla truncata'' in 1959 and later established the genus ''Xenohyla ''Xenohyla'' is a ...

Vernal Pool
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish. Certain tropical fish lineages (such as killifishes) have however adapted to this habitat specifically. Vernal pools are a type of wetland. They can be surrounded by many communities/species including deciduous forest, grassland, lodgepole pine forest, blue oak woodland, sagebrush steppe, succulent coastal scrub and prairie. These pools are characteristic of Mediterranean climates, but occur in many other ecosystems. Generation and annual development During most years, a vernal pool basin will experience inundation from rain/precipitation, followed by desiccation from evapotranspiration. These conditions are commonly associated with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1998
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Endemic Fauna Of Brazil
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 to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenohyla
''Xenohyla'' is a genus of tree frogs in the family Hylidae that is endemic to xeric habitats of coastal Brazil, with '' Xenohyla eugenioi'' native to the State of Bahia and the State of Sergipe, and '' Xenohyla truncata'' native to the State of Rio de Janeiro. This genus is characterized by a robust body, wide flat head, short snout, short forelimbs with muscular forearms, and a truncate-shaped body when viewed from above. They are associated with bromeliads, where they hide during the day and eat the insects that also inhabit the plant. They breed in temporary pools that are formed by rainwater. Both species are orange or brown with a white stripe going down their dorsal edges. ''X. truncata'' loses this stripe when it matures but ''X. eugenioi'' keeps it as an adult. '' Xenohyla truncata'' is unique in the fact that it is the only known frugivorous amphibian. It locates fruit and swallows it whole, and is known to defecate out viable seeds that help in the spread of the plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugênio Izecksohn

Herpetology
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning " reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists a ...

Brazilians
Brazilians ( pt, Brasileiros, ) are the citizens of Brazil. A Brazilian can also be a person born abroad to a Brazilian parent or legal guardian as well as a person who acquired Brazilian citizenship. Brazil is a multiethnic society, which means that it is home to people of many ethnic origins, and there is no correlation between one's stock and their Brazilian identity. Being Brazilian is a civic phenomenon, rather than an ethnic one. As a result, the degree to which Brazilian citizens identify with their ancestral roots varies significantly depending on the individual, the region of the country, and the specific ethnic origins in question. Most often, however, the idea of ethnicity as it is understood in the anglophone world is not popular in the country. In the period after the colonization of the Brazilian territory by Portugal, during much of the 16th century, the word "Brazilian" was given to the Portuguese merchants of Brazilwood, designating exclusively the name of ...

Frugivore
A frugivore is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is a form of mutualism. Frugivore seed dispersal Seed dispersal is important for plants because it allows their progeny to move away from their parents over time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to consume them and move the plant's seeds from place to place. While many fruit-producing plant species would not disperse far without frugivores, their seeds can usually germinate even if they fall to the ground directl ...

Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Because tails are often missing or absent, especially in juveniles, SVL is seen as more invariant than total length. Even in the case of crocodiles, tail tips may be missing. Methods The measurements may be taken with dial calipers or digital calipe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agreste
The agreste (, "countryside") is a narrow zone of Brazil in the states of Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe and Bahia between the coastal forest '' zona da mata'' and the semiarid ''sertão''. The agreste fades out after it reaches Rio Grande do Norte due to the break of the mountain-chain that blocks air currents from the Atlantic ocean. This barrier is what induces high rainfalls in the coastal Atlantic forest zone. Most of the agreste is hilly, its hills becoming higher at south, except near the narrow valley of São Francisco River. This land is mostly used for mixed farming, prevailing fruits, of which melons have especial importance. Like the sertão, the agreste is frequently affected by drought, though generally with less severe effects. Only some highland regions mostly in Pernambuco, where cities like Garanhuns and Triunfo are located, are able to reach temperatures below 10 degrees Celsius for a part of the year, usually coinciding with the ...

Tree Frog
A tree frog (or treefrog) is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several lineages of frogs among the Neobatrachia have given rise to treefrogs, although they are not closely related to each other. Millions of years of convergent evolution have resulted in very similar morphology even in species that are not very closely related. Furthermore, tree frogs in seasonally arid environments have adapted an extra-epidermal layer of lipid and mucus as an evolutionary convergent response to accommodate the periodic dehydration stress. Description As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults. Tree frogs are usually tiny as their weight has to be carried by the branches and twigs in their habitats. While some reach 10&n ...
