Suwon Tree Frog
''Dryophytes suweonensis'', the Suweon treefrog or Suwon treefrog, is a species of frog in the family Hylidae endemic to the Korean Peninsula probably from the Imjin River to the Mangyeong River, south of Iksan. Its distribution and population have been assessed to be below 800 individuals and the status of the species has been updated as Endangered by the IUCN. The natural habitat of the species has been generally transformed into rice fields and it is threatened by habitat loss. The population size of the species has very strongldeclined in population size similarly to the sister species '' Dryophytes immaculatus'' and '' Dryophytes flaviventris''. The Suweon tree frog and the Japanese tree frog, which is also found in the same region, are the only two hylid species found on the Korean Peninsula. Factors distinguishing them include the frequency of the call, calling behavior, webbing between the toes and the angle of the line between eyes and nostrils. The type locality for ...

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] |
Rice Paddy
A paddy field is a flooded field of arable land used for growing semiaquatic crops, most notably rice and taro. It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures. It was spread in prehistoric times by the expansion of Austronesian peoples to Island Southeast Asia, Southeast Asia including Northeastern India, Madagascar, Melanesia, Micronesia, and Polynesia. The technology was also acquired by other cultures in mainland Asia for rice farming, spreading to East Asia, Mainland Southeast Asia, and South Asia. Fields can be built into steep hillsides as terraces or adjacent to depressed or steeply sloped features such as rivers or marshes. They require a great deal of labor and materials to create and need large quantities of water for irrigation. Oxen and water buffalo, adapted for life in wetlands, are important working animals used extensively in paddy field farm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryophytes
''Dryophytes'' is a genus of Ameroasian tree frogs in the family Hylidae. They are found mostly in North America, but the genus also includes three species found in eastern Asia. Description ''Dryophytes'' consists of small tree-dwelling frogs, usually green or gray in color. They have digits ending with expanded discs to help them sick to surfaces like trees. Habitat These tree frogs are found in wetlands throughout their range, as well as in temperate forests both on the ground and in trees. Taxonomy The genus was first described by Fitzinger in 1843. Later it was placed into the genus ''Hyla'', the true tree frogs, by Boulenger in 1882. Fouquette and Dubois 2014, treated ''Dryophytes'' as a subgenus of ''Hyla''. ''Dryophytes'' was finally resurrected as an independent genus by Duellman et al. in 2016. Only geographical, rather than morphological, differences separates ''Dryophytes'' from the genus ''Hyla''. ''Hyla'' is found only in the Old World, whereas ''Dryo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Korea
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 ...

List Of Amphibians Of Korea
This is a list of amphibian species found in the wild in Korea, including the Korean Peninsula and Jeju Island. A total of 20 species of amphibians are known from Korea; this includes two species of salamander that were not discovered until the 21st century. This list treats the taxonomic designations found in Frost (2007) as authoritative. There have been major revisions of amphibian Taxonomy (biology), taxonomy, including the taxonomy of many Korean species, since the late 20th century. This has included studies which have found species such as the Korean brown frog and Imienpo Station frog, which were previously considered to be Korean varieties or subspecies of more widespread species, to be distinct. It has also included a wholesale revision of the taxonomy of the Ranidae, or true frogs—for example, the common dark-spotted frog was formerly classified as ''Rana (genus), Rana nigromaculata'' but is now classified as ''Pelophylax nigromaculatus''.

Invasive Species In The United States
Invasive species are a significant threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. The term "invasive species" can refer to introduced/naturalized species, feral species, or introduced diseases. Some introduced species, such as the dandelion, do not cause significant economic or ecologic damage and are not widely considered as invasive. Economic damages associated with invasive species' effects and control costs are estimated at $120 billion per year. Notable invasive species } , - , , , , Giant African land snail , , ''Lissachatina fulica'' , , Florida , , Pest control , , This invasive species was smuggled into Florida from Africa.

Korean Peninsula
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to civi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** ''Boana'' – gladiator treefrogs *** ''Bokermannohyla'' *** ''Hyloscirtus'' *** ''Myersiohyla'' *** ''Nesorohyla'' *** '' "Hyla" nicefori'' ** Tribe Dendropsophini ***''Dendropsophus'' *** '' Julianus'' *** ''Lysapsus'' ...
