Leptopelis Macrotis
''Leptopelis macrotis'', sometimes called the big-eyed forest tree frog, is a species of frog in the family Arthroleptidae. It is found in the rainforests of Sierra Leone, southern Guinea, Liberia, Ivory Coast, and southern Ghana. Notice that similar common name "big-eyed tree frog" is sometimes used for ''Leptopelis vermiculatus'' from Tanzania and for ''Litoria exophthalmia'' from New Guinea. Description ''Leptopelis macrotis'' is a large ''Leptopelis'' species: females measure in snout–vent length, while males are more modest at SVL. The Dorsum (anatomy), dorsum is smooth and transversely-striped in shades of brown. The Tympanum (anatomy), tympanum is large. The feet are fully webbed. Habitat and conservation Its natural habitats are primary rainforests at elevations of above sea level. It lives Arboreal locomotion, arboreally along streams; males can often be heard calling from branches near streams some 5–10 m above the ground. ''Leptopelis macrotis'' is a relatively ...

Frog
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the 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 dating suggests their split from other amphibians may extend further back to the Permian, 265 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 or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs ...

Agricultural Expansion
Agricultural expansion describes the growth of agricultural land ( arable land, pastures, etc.) especially in the 20th and 21st centuries. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself), with an estimated expectation of 10 to 11 billion humans on Earth by end of this century. It is foreseen that most of the world's non-agrarian ecosystems ( terrestrial and aquatic) will be affected adversely, from habitat loss, land degradation, overexploitation, and other problems. The intensified food (and biofuel) production will in particular affect the tropical regions. Most modern agriculture relies on intensive methods. Further expansion of the predominant farming types that rest on a small number of highly productive crops has led to a significant loss of biodiversity on a global scale already. ...

Amphibians Described In 1967
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 declin ...

Leptopelis
''Leptopelis'' is a genus of frogs in the family Arthroleptidae. They are found throughout Sub-Saharan Africa, excluding Madagascar. It is placed in monotypic subfamily Leptopelinae, although this subfamily is not always recognized. They have a number of common names, including forest treefrogs, tree frogs, leaf-frogs, and big-eyed frogs. Description ''Leptopelis'' are mostly medium-sized frogs (snout–vent length ), but '' Leptopelis palmatus'' can reach . Tympanum is present. Most species have expended digit tips. Ecology ''Leptopelis'' are mainly arboreal, but some species, especially in more arid areas, are terrestrial or even subfossorial. Breeding typically starts with the heavy rains in the beginning of the wet season. Eggs may be deposited either in water or in/on the ground. Development includes a free-living tadpole stage, with a possible exception of '' Leptopelis brevirostris'', whose large eggs suggest that development could be direct. Males typically call in bu ...

Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are 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, 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 taxon is Vulnerable when it is not critically endangered or Endangered but ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships.

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almos ...

Gola Rainforest National Park
The Gola Rainforest National Park (GRNP) was declared by President of Sierra Leone Ernest Bai Koroma and enacted by the Parliament of Sierra Leone in December 2010. The park amalgamates Gola North Forest Reserve, Gola East Forest Reserve and Gola West Forest Reserves, and is Sierra Leone's second national park. The GRNP is Sierra Leone's largest tract of rainforest, and covers 71,070 hectares in the east of the country. Recent biological surveys show that the forest is home to more than 330 species of birds, 14 of which are threatened, over 650 species of butterfly and 49 species of mammals, including a population of 300+ chimpanzees, pygmy hippopotamuses and a much dwindled forest elephant population. The GRNP is part of the Upper Guinea Forest, a biodiversity hotspot that stretches from Guinea to Togo. The forest has been commercially exploited in the past, with over 20,000 hectares being logged between the 1960s and 1980s, and has recently been under pressure for the ...
