Dendrobates Arboreus
The polkadot poison frog (''Oophaga arborea'') is a species of frogs in the family Dendrobatidae endemic to Panama, where it is known as rana venenosa in Spanish. Its natural habitats are humid lowland and montane forests. It is threatened by habitat loss and is listed by the IUCN as being "critically endangered". Description The snout-to-vent length of the polkadot poison frog is . The hind limbs are short and the forelimbs relatively long with large hands. The fingers are unwebbed, the second one being longer than the first, and all but the first finger have flat discs of thickened skin. This frog has brown eyes and no teeth in its upper jaw. Males have a small vocal sac on the throat, and when not in use, this hangs in folds. The skin on the belly and inside the thighs is coarsely wrinkled. This frog is black or some shade of brown with roundish yellow spots, which often have a raised surface. The call made by the male is similar to that of closely related species but can be di ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granular Poison Frog
The granular poison frog or granular poison arrow frog (''Oophaga granulifera'') is a species of frog in the family Dendrobatidae, found in Costa Rica and Panama. Originally described as ''Dendrobates granuliferus'', it was moved to ''Oophaga'' in 1994. Its natural habitats are tropical humid lowland forests; it is threatened by habitat loss. Description The granular poison frog is a small frog with slender limbs growing to about . Its skin is finely granulated and its colour is typically bright orange head, body and upper arms and bluish-green underparts, legs and lower arms. In the vicinity of Quepos, Costa Rica, there is a colour morph in which the orange colour is replaced with olive green. Distribution and habitat The granular poison frog is native to Costa Rica and Panama. Its range extends from southwestern Costa Rica through the adjacent area of south-western Panama at heights of up to above sea level. It also occurs in Piedras Blancas National Park in south-eastern Cos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibians Described In 1984
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 ...

Oophaga
''Oophaga'' is a genus of poison-dart frogs containing twelve species, many of which were formerly placed in the genus ''Dendrobates''. The frogs are distributed in Central and South America, from Nicaragua through the Colombian El Choco to northern Ecuador (at elevations below ). Their habitats vary with some species being arboreal while other being terrestrial, but the common feature is that their tadpoles are obligate egg feeders. Etymology ''Oophaga'', Greek for "egg eater" (''oon'', '), is descriptive of the tadpoles' diet.Zimmermann, E. and Zimmermann, H. 1994.

Bosque Protector Palo Seco
A bosque ( ) is a type of gallery forest habitat found along the riparian flood plains of stream and river banks in the southwestern United States. It derives its name from the Spanish word for 'woodlands'. Setting In the predominantly arid or semi-arid southwestern United States, a bosque is an oasis-like ribbon of green vegetation, often canopied, that only exists near rivers, streams, or other water courses. The most notable bosque is the -long ecosystem along the valley of the middle Rio Grande in New Mexico that extends from Santa Fe south to El Paso, Texas. One of the most famous and ecologically intact sections of the bosque is included in the Bosque del Apache National Wildlife Refuge. Flora and fauna Common trees in the bosque habitat include mesquite, cottonwood, desert willow, and desert olive. Because there is often only a single canopy layer and because the tree species found in the bosque are generally deciduous, a wide variety of shrubs, grasses, ...

Parque Internacional La Amistad
The La Amistad International Park, or in Spanish , formerly the La Amistad National Park, is a Transboundary Protected Area in Latin America, management of which is shared between Costa Rica ( Caribbean La Amistad and Pacific La Amistad Conservation Areas) and Panama, following a recommendation by UNESCO after the park's inclusion in the World Heritage Site list in 1983. The park and surrounding Biosphere Reserve is one of the most outstanding conservation areas in Central America, preserving a major tract of tropical forest wilderness. It is world-renowned for its extraodinary biodiversity and endemism. Geography La Amistad International Park is equally split between Costa Rica and Panama, as part of the former ''La Amistad Reserves''. The park protects a large part of the Cordillera de Talamanca mountain range, including the highest point in Costa Rica, Cerro Chirripó. It covers 401,000 ha of tropical forest and is the largest nature reserve in Central America; together with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromeliad
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, ''Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss (''Tillandsia usneoides''), and 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, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species that gath ...

Epiphyte
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dendrobatidae
Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the Family (biology), family Dendrobatidae which are native to tropical Central and South America. These species are Diurnality, diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them Aposematism, aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have Crypsis, cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this feature from their diet of ants, mites and termites. However, other species that exhibit cryptic coloration, and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are Threatened species, threatened due to human infrastructure encroaching on their habitats. These amphibians ...
