Meristogenys Maryatiae
''Meristogenys maryatiae'', also known as Maryati's torrent frog, is a species of frog in the family Ranidae. It is endemic to the state of Sabah, in the Malaysian part of Borneo. The specific name honours Prof. Datin Mohamed Maryati, entomologist from the Universiti Malaysia Sabah, who helped the describers of this species during their herpetological surveys in Sabah. Description Adult males measure and adult females, based on just two specimens, in snout–vent length. The body is moderately slender. The head is triangular and wider than it is long. The tympanum is distinct, but the supratympanic fold is weak. The fingers are slender and have tips of expanded into discs; no webbing is present. The hindlimbs are slender. The toe tips bear discs similar to the finger ones. The toes are fully webbed. The dorsum is shagreened. The dorsolateral folds are low and indistinct. Dorsal colouration is olive brown with dark spots. The iris is golden. The limbs have alternating light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Endemic Fauna Of Malaysia
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meristogenys
''Meristogenys'' is a genus of true frogs from Borneo. Its tadpoles are adapted to fast-flowing mountain streams and easily recognizable by their divided upper lip with ribs on the outside.Stuart (2008) Taxonomy and systematics Its closest living relative is apparently the hole-in-the-head frog (''Huia cavitympanum''), type species of the highly polyphyletic "wastebin genus" ''Huia''. ''Meristogenys'', having been proposed far more recently than ''Huia'', might be included in the latter on grounds of phylogeny, as most if not all species placed in the ''Huia'' seem to belong elsewhere. But a group of species traditionally placed in ''Huia'' as well as the genus ''Clinotarsus'' are very close relatives, and therefore a taxonomic revision of this group is probably better deferred until the relationships of all taxa involved have been properly assessed.Cai ''et al.'' (2007), Stuart (2008) ''Meristogenys'' on its own is a monophyletic group. Ecology ''Meristogenys'' are common frogs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinabalu National Park
Kinabalu Park ( ms, Taman Kinabalu), established as one of the first national parks of Malaysia in 1964, is Malaysia's first World Heritage Site designated by UNESCO in December 2000 for its "outstanding universal values" and the role as one of the most important biological sites in the world with more than 4,500 species of flora and fauna, including 326 bird and around 100 mammal species, and over 110 land snail species.

Crocker Range National Park
Crocker Range National Park ( ms, Taman Negara Banjaran Crocker) was established in 1984, although the area had previously been under protection as a forest reserve. It covers the north-south Crocker Range, of 1200-1800 metre mountains in Sabah, Malaysia. In the vicinity of park headquarters, there is a resort that provides accommodation and food services. Other visitors facilities such as an exhibition centre, insectarium, fernarium, observation tower and trekking trail can also be found. The park covers 1,399 km², making it the largest park in Sabah. The park consists of both hill and mountain forest, with many species of flora and fauna endemic to Borneo. Maintenance of this forest cover is essential to ensuring a pure water supply for many of the towns and communities in Sabah. The park contains at least five species of primates, such as the orang-utan, gibbons and the furry tarsier with its enormous round eyes, and extremely sociable long-tailed macaques. The Padas R ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Crocker Range
Crocker Range ( ms, Banjaran Crocker) is a mountain range in West Coast Division of Sabah, Malaysia that separates the west and east coast of Sabah. At an average height of , it is the highest mountain range in the state with the range is named after the British administrator in North Borneo, William Maunder Crocker. Geology The range is made up of uplifted and folded sedimentary rocks consisted of weathered soft sandstones and shales. The highest point is Mount Kinabalu at . Most of the park boundary lies above with its lowlands used for cash crops and paddy field. On the east of the range located the Tambunan Valley at which are mainly terraced paddy fields and groves of bamboos border the north-eastern part of the protected park. The park area is important as a water catchment to supply water into various river in the west coast and interior districts of Sabah including Papar River, Kimanis River, Bongawan River, Membakut River, Padas River and Melalap River that flow wes ...

Gosner Stage
Gosner stage is a generalized system of describing stages of embryonal and larval development in anurans (frogs and toads). The Gosner system includes 46 numbered stages, from fertilized embryo (stage 1) to the completion of metamorphosis (stage 46). It was introduced by Kenneth Gosner in 1960. The system is widely used in herpetology to describe tadpoles. Gosner stages are based on certain morphological landmarks that allow comparing development in different species that may greatly differ in age or size. Developmental stages The Gosner system includes 46 stages, from fertilized embryo (stage 1) to the completion of metamorphosis (stage 46). In the original publication, only two major developmental stages were distinguished, embryonic or prefeeding stages (1–25) and larval stages (26–46). McDiarmid and Altig (1999) distinguish four major developmental stages, as detailed in the table below. In ecological literature, the term "hatchling" may refer to stages 24–26. How ...
