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] |
Xenohyla Truncata
''Xenohyla truncata'', the Izecksohn's Brazilian treefrog, is a species of frugivorous tree frog in the family Hylidae. It is endemic to the State of Rio de Janeiro, Brazil. The range of this frog ranges from the southern border of Espírito Santo down to Ilha da Marambaia, inhabiting mostly restingas near the coast and on some islands. They shelter inside bromeliads such as '' Neoregelia cruenta'' during the day and breed in temporary pools. When disturbed, this tree frog will tilt its head down, outstretch its legs, and puff up. This posture breaks up the frogs outline and makes it appear larger. These tree frogs are listed as near threatened because they are restricted to an area of less than 20,000 square kilometres and because human development modifies or destroys their restinga habitats. As a juvenile, ''Xenohyla truncata'' has white stripes down the sides of its body but they disappear at maturity, leaving the adult frog a uniform brown or orange. This species of frog is ...

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 ...

Amphibian
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 dramat ...

Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as " tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** '' Boana'' – gladiator treefrogs *** '' Bokermannohyla'' *** '' Hyloscirtus'' *** '' Myersiohyla'' *** '' Nesorohyla'' *** ''"Hyla" nicefori'' ** Tribe Dendropsophini ***'' Dendropsophus'' *** '' Julianus'' *** '' Lysap ...

Eugênio Izecksohn
Eugênio Izecksohn (1932 – June 2013) was a Brazilian people, Brazilian Herpetology, herpetologist."Eugênio Izecksohn, especialista em anfíbios, morre aos 81 anos" ''O Globo'' (June 4, 2013). (In Portuguese language, Portuguese). Izecksohn graduated from ''Universidade Federal Rural do Rio de Janeiro'' in 1953. Among others, he discovered and scientifically described the flea frog ''Brachycephalus didactylus'', one of the smallest frogs in the world. Several taxa have been named in honour of him, mostly frogs like the tiny ''Brachycephalus izecksohni, B. izecksohni'', and the extremely rare—if not already e ...

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 ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
