Agalychnis Annae
The blue-sided leaf frog (''Agalychnis annae''), also known as the orange-eyed leaf frog, is an endangered species of tree frog in the subfamily Phyllomedusinae native to the tropical rainforests of Costa Rica and Panama. The specific name ''annae'' honors Ann S. Duellman, the collector of the holotype and the describer's wife. Distribution and habitat This tree frog is known only from the Central Valley of Costa Rica, on the slopes of the Cordillera de Talamanca, the Cordillera de Tilarán and the Cordillera Central ranges, at altitudes between about . The total extent of its range is estimated to be around . There may be a subpopulation in the Cerro Colorado range in western Panama, as suggested by a single female being found there (2012). Much of the forest in which the frog lives has been cleared, so there are a number of subpopulations separated by coffee plantations, cultivated areas and urban areas. Status ''Agalychnis annae'' is fairly common in parts of the Central Va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heredia, Costa Rica
Heredia () is a district in the Heredia canton of Heredia province, Costa Rica. As the seat of the municipality of Heredia canton, it is awarded the status of city, and by virtue of being the city of the first canton, it is the Province Capital of Heredia province as well. It is 10 kilometers to the north of the country's capital, San José. The city is home to one of the largest colleges in Costa Rica, the National University of Costa Rica, which accepts many international students. History Prior to its founding, the area around Heredia was inhabited by the native tribe that is known as the Huetares, who were commanded at the coming of the Spanish by the ''Cacique'' Garabito. In 1706 settlers from Cartago, set up a small church at a place they called "Alvirilla", which soon became more populated. Between 1716 and 1717 the settlers moved their village to the north, to a place the indigenous people called Cubujuquí. In 1736 Heredia was deemed sufficiently large to be gran ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Amphibians Of Costa Rica
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

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] |
Batrachochytrium Dendrobatidis
''Batrachochytrium dendrobatidis'' ( ), also known as ''Bd'' or the amphibian chytrid fungus, is a fungus that causes the disease chytridiomycosis in amphibians. Since its discovery in 1998 by Lee Berger, the disease devastated amphibian populations around the world, in a global decline towards multiple extinctions, part of the Holocene extinction. A recently described second species, '' B. salamandrivorans'', also cause chytridiomycosis and death in salamanders. The fungal pathogens that cause the disease chytridiomycosis ravage the skin of frogs, toads, and other amphibians, throwing off their balance of water and salt and eventually causing heart failure, Nature reports. Some amphibian species appear to have an innate capacity to withstand chytridiomycosis infection due to symbiosis with ''Janthinobacterium lividum''. Even within species that generally succumb, some populations survive, possibly demonstrating that these traits or alleles of species are being subjected to evo ...

Monteverde Biological Reserve
Monteverde is the twelfth canton of the Puntarenas province of Costa Rica. It is located in the Cordillera de Tilarán mountain range. Roughly a four-hour drive from the Central Valley, Monteverde is one of the country's major ecotourism destinations. The area is host to the Monteverde Cloud Forest Reserve and several other natural attractions, which draw considerable numbers of tourists and naturalists. National Geographic has called the Monteverde Cloud Forest Biological Reserve "the jewel in the crown of cloud forest reserves". Newsweek has declared Monteverde the world's #14 "Place to Remember Before it Disappears". By popular vote in Costa Rica, Monteverde was deemed one of the ''Seven Natural Wonders of Costa Rica'', along with Isla del Coco, Volcán Arenal, Cerro Chirripó, Río Celeste, Tortuguero, and Volcán Poás.

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 ...
