Allobates Bromelicola
''Allobates bromelicola'' (common name: coastal rocket frog) is a species of frog in the family Aromobatidae. It is endemic to the Venezuelan Coastal Range in the Aragua state. Habitat This arboreal, diurnal frog has been found in close association with bromeliad plants growing in cloud forests between 1310 and 1375 meters above sea level. The frog's known range overlaps one protected area, Henri Pittier National Park. Reproduction Scientists have observed tadpoles swimming in phytotelms of bromeliad plants and infer that the female frog lays her eggs in or on these plants. There are no recorded cases of an adult frog being observed carrying tadpoles to water, as in other species in ''Allobates''. Threats The IUCN classifies this frog as vulnerable to extinction. Although the ability of the fungus '' Batrachochytrium dendrobatidis'' to infect this species has not been confirmed, scientists suspect the fungal disease chytridiomycosis Chytridiomycosis ( ) is an infectiou ...

Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Aromobatidae
The Aromobatidae are a family of frogs native to Central and South America. They are sometimes referred to as cryptic forest frogs or cryptic poison frogs. They are the sister taxon of the Dendrobatidae, the poison dart frogs, but are not as toxic as most dendrobatids are. Taxonomy The Aromobatidae were separated from the Dendrobatidae only in 2006, and some sources continue to treat these frogs as part of the Dendrobatidae. However, their position as the sister taxa is well supported, and the question is primarily about whether they should be ranked as a family or a subfamily. The validity of subfamilies within the Aromobatidae is also unsettled. Some evidence points to paraphyly of at least the subfamily Anomaloglossinae, and genus ''Allobates'', largely because of the uncertain placement of '' Allobates olfersioides''. Some species are reported to have a skunk like odor. This strong odor is secreted through the skin but theses frogs are not toxic. This strong odor is used a ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Venezuelan Coastal Range
The Venezuelan Coastal Range ( or ), also known as Venezuelan Caribbean Mountain System (), is a mountain range system and one of the eight natural regions of Venezuela, that runs along the central and eastern portions of Venezuela's northern coast. The range is a northeastern extension of the Andes, and is also known as the Maritime Andes. It covers around 48,866 km2, being the 4th largest natural region in Venezuela. Geography The Coastal Range consists of two parallel ranges, which run east and west along the coast of the Caribbean Sea. The Cojedes River separates the western end of the Coastal Range from the Cordillera de Mérida to the southeast. The range is divided into eastern and western sections by the wide bay between Cape Codera and Cumaná. Serranía del Litoral—Serranía del Interior In the eastern section of the range, the parallel ranges are known as the Serranía del Litoral, which runs along the Caribbean coast, and the Serranía del Interior to the south ...

Aragua
Aragua State (, ) is one of the 23 states of Venezuela. It is located in the north-central region of Venezuela. It has plains, jungles and Caribbean beaches. The most popular beaches are Cata and Choroni. It has Venezuela's first national park, Henri Pittier National Park. The capital is Maracay. Other important cities include Turmero and El Limón. Aragua State covers a total surface area of and, based on the 2011 census information, the estimated population of Aragua State in 2012 is 1,630,308 inhabitants. Etymology The name of the state comes from an indigenous word of Cumanagoto (Caribbean) origin, which is used to refer to the Chaguaramo, a type of palm from the region uotation requiredHowever, according to Carlos Blanco Galeno, a chronicler from Turmero, it derives from the Cariban ''aregua'', with the morphemes ''are'' ('site') and ''gua'', which in turn derives from ''ogun'' ('my thing'); so ''aregua'' would mean 'my place, my country'.

Bromeliad
The Bromeliaceae (the bromeliads) are a Family (biology), family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the Tropics, tropical Americas, with several species found in the American subtropics and one in tropical west Africa, ''Pitcairnia feliciana''. It is among the basal (phylogenetics), basal families within the Poales and is the only family within the order that has Septal nectary, septal nectaries and Ovary (plants), inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These Ovary (plants), inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss (''Tillandsia usneoides''), and Terrestrial plant, terrestrial species, such as the pineapple (''Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Pittier National Park
Henri Pittier National Park is the oldest national park in Venezuela, originally created in 1937 under the name of ''Rancho Grande'' by decree of President Eleazar López Contreras. In 1953 the park was renamed in honor of Henri Pittier, a distinguished Swiss people, Swiss geographer, botanist and ethnologist, who arrived in Venezuela in 1917, classified more than 30,000 plants in the country and devoted many years studying the flora and fauna in the park. Henri Pittier National Park has the honor of having started the history of national parks of Venezuela. Its 107,800 hectares, located in the north of Aragua state, comprise most of the Araguan coast and mountainous area of Carabobo state. It also borders San Esteban National Park. Henri Pittier National Park is the largest among the national parks of the Venezuelan Coastal Range. The park consists of two geographic systems: a steep mountainous interior where there are more than 500 bird species and 22 Endemism, endemic species ...

Chytridiomycosis
Chytridiomycosis ( ) is an infectious disease in amphibians, caused by the chytrid fungi '' Batrachochytrium dendrobatidis'' and '' Batrachochytrium salamandrivorans''. Chytridiomycosis has been linked to dramatic population declines or extinctions of amphibian species in western North America, Central America, South America, eastern Australia, east Africa (Tanzania), and Dominica and Montserrat in the Caribbean. Much of the New World is also at risk of the disease arriving within the coming years. The fungus is capable of causing sporadic deaths in some amphibian populations and 100% mortality in others. No effective measure is known for control of the disease in wild populations. Various clinical signs are seen by individuals affected by the disease. A number of options are possible for controlling this disease-causing fungus, though none has proved to be feasible on a large scale. The disease has been proposed as a contributing factor to a global decline in amphibian popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allobates
''Allobates'' is a genus of frogs in the family Aromobatidae. They are native to the Central and South Americas, from Nicaragua to Bolivia and Brazil, with one species on Martinique. Description and ecology Species of the genus ''Allobates'' are mostly small frogs. Dorsal colouration is cryptic, with the exception of the ''Allobates femoralis'' group that has bright colours. They are mostly terrestrial frogs found in the leaf litter of tropical rain forests. Most species deposit eggs in the leaf litter; tadpoles are transported to the water on the backs of the parents. '' Allobates nidicola'' and '' Allobates chalcopis'', however, have endotrophic tadpoles that develop into froglets in the nest, without entering water. Taxonomy There are many species recognised in the genus ''Allobates'': References External links * *"The Chirping Frog"- 2018 BBC internet article on new species found in the Pico da Neblina National Park Pico da Neblina National Park () is a national p ...

Amphibians Of Venezuela
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...
