List Of Amphibians Of Japan
This list of amphibians recorded in Japan is primarily based on the International Union for Conservation of Nature, IUCN IUCN Red List, Red List, which details the conservation status of some ninety-four species. Of these, four are assessed as critically endangered (the Endemism, endemic Amakusa salamander, Mikawa salamander, Tosashimizu salamander, and Tsukuba clawed salamander), twenty-seven as Endangered species, endangered, fourteen as Vulnerable species, vulnerable, eleven as Near-threatened species, near threatened, and thirty-eight as of Least-concern species, least concern. According to statistics accompanying the 2020 Japanese Ministry of the Environment (Japan), Ministry of the Environment (MoE) Japanese Red List, Red List, ninety-one species and subspecies are to be found, but the conservation status of only sixty-seven is detailed. Of these, five Taxon, taxa are critically endangered from a national perspective, twenty are endangered, twenty-two vulnerable, nineteen nea ...

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. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983). (see also precautionary principle). See also * IUCN Red List data deficient species * List of data deficient amphibians * IUCN Red List data deficient species (Annelida) * List of data deficien ...

Bufo
''Bufo'' is a genus of true toads in the amphibian family Bufonidae. As traditionally defined, it was a wastebasket genus containing a large number of toads from much of the world, but following taxonomic reviews most of these have been moved to other genera, leaving only seventeen extant (living) species from Europe, northern Africa and Asia in this genus, including the well-known common toad (''B. bufo''). Some of the genera that contain species formerly placed in ''Bufo'' are ''Anaxyrus'' (many North American species), ''Bufotes'' (European green toad and relatives), ''Duttaphrynus'' (many Asian species, including the Asian common toad introduced elsewhere), ''Epidalea'' (natterjack toad) and ''Rhinella'' (many Latin American species, including the cane toad introduced elsewhere). Description True toads have in common stocky figures and short legs, which make them relatively poor jumpers. Their dry skin is thick and "warty". Behind their eyes, ''Bufo'' species have wart-li ...

Rhacophorus Arboreus 01s
''Rhacophorus'' is a genus of frogs in the shrub frog family ( Rhacophoridae) and the related Hylidae make up the true tree frogs. They are found in India, Japan, Madagascar, Africa, and Southeast Asia. Over 40 species are currently recognised. These frogs have long toes with strong webbing between them, enabling the animals to slow their fall to a glide, a form of arboreal locomotion known as parachuting. They are, therefore, among the anurans commonly known as "flying frogs". The present genus is closely related to ''Polypedates'', which in former times was often included in ''Rhacophorus''. Even today, it is not fully resolved in which of these genera '' "P." feae'' and the Chinese flying frog (''"R." dennysi'') properly belong, and the supposedly new species ''"P. pingbianensis"'' has turned out to be the same as '' R. duboisi''. Reproduction These frogs lay their eggs in aerial foam nests; upon hatching, tadpoles drop to the water under the nest and complete their d ...

Rana Ishikawae
Ishikawa's frog (''Odorrana ishikawae'') is a species of frog in the family Ranidae. It is endemic to Okinawa Island, one of the Ryukyu Islands of Japan Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north .... It has been described as the most beautiful frog in Japan. Its natural habitats are temperate forests, rivers, and intermittent rivers. It is threatened by habitat loss.

Pelophylax Porosus - 2
''Pelophylax'' is a genus of true frogs widespread in Eurasia, with a few species ranging into northern Africa. This genus was erected by Leopold Fitzinger in 1843 to accommodate the green frogs of the Old World, which he considered distinct from the brown pond frogs of Carl Linnaeus' genus ''Rana''. They are also known as water frogs, as they spend much of the summer living in aquatic habitat; the pond frogs can be found more often, by comparison, on dry land, as long as there is sufficient humidity. Yet there are species of Eurasian green frogs – the Central Asian '' P. terentievi'', or the Sahara frog (''P. saharicus'') – which inhabit waterholes in the desert. Systematics and taxonomy Most authors throughout the 19th and 20th century disagreed with Fitzinger's assessment. The green frogs were included again with the brown frogs, in line with the tendency to place any frog similar in habitus to the common frog (''R. temporaria'') in ''Rana''. That g ...

Hyla Japonica Sep01
''Hyla'' is a genus of frogs in the tree frog family Hylidae. As traditionally defined, it was a wastebasket genus with more than 300 species found in Europe, Asia, Africa, and across the Americas. After a major revision of the family most of these have been moved to other genera so that ''Hyla'' now only contains 17 extant (living) species from Europe, northern Africa and Asia. The earliest known fossil member of this genus is †''Hyla swanstoni'' from the Eocene of Saskatchewan, Canada, but its designation to ''Hyla'' happened before the major revision, meaning that its position needs confirmation. The genus was established by Josephus Nicolaus Laurenti in 1768. It was named after Hylas in Greek mythology, the companion of Hercules. The name is unusual in that – though Laurenti knew that Hylas was male – the name is unambiguously treated in the feminine grammatical gender for reasons unknown. The etymology of the name is also often incorrectly given as being d ... [...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] |
