Kurixalus Berylliniris
''Kurixalus berylliniris'' is a species of tree frog in the family Rhacophoridae. It is endemic to Taiwan and occurs in the eastern part of the island at moderate elevations. Prior to its description in 2016, it was confused with ''Kurixalus eiffingeri''. The specific name ''berylliniris'' combines the Latin words ''beryllin'' (meaning "green-colored") and ''iris'', in reference to the green iris of this frog. Taxonomy and systematics ''Kurixalus berylliniris'' was described in 2016. It resembles ''Kurixalus eiffingeri'' but displays some morphological differences and a different reproductive season. Furthermore, molecular data and male advertisement call differentiate it from ''Kurixalus eiffingeri'' and '' Kurixalus wangi'', its sister species. Together these three species form a lineage that is clearly separate from '' Kurixalus idiootocus'', the fourth ''Kurixalus'' species in Taiwan.

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 ...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Amphibians Of Taiwan
At least 37 species of amphibians are native to Taiwan. This list does not include the provisionally recorded ''Fejervarya kawamurai'' nor the introduced ''Rhinella marina'' and ''Andrias davidianus''. Of these, 17 species are endemic to Taiwan. Salamander '' Echinotriton andersoni'' is considered extinct in Taiwan (but survives on the Ryukyu Islands of Japan). In addition, there are three introduced species: cane toad ''Rhinella marina'', bullfrog ''Lithobates catesbeianus'', and Chinese giant salamander ''Andrias davidianus''. Thus, in total 40 amphibians have been recorded in Taiwan. Anura (frogs and toads) Family Bufonidae — true toads * ''Bufo bankorensis'' Barbour, 1908 — endemic * ''Duttaphrynus melanostictus'' (Schneider, 1799) * ''Rhinella marina'' (Linnaeus, 1758) — introduced Family Dicroglossidae — fork-tongued frogs * ''Fejervarya cancrivora'' (Gravenhorst, 1829) * ''Fejervarya kawamurai'' Djong, Matsui, Kuramoto, Nishioka, and Sumida, 2011 — provisional ...

Kurixalus
''Kurixalus'' is a genus of frogs in the family Rhacophoridae. The taxonomy of small rhacophids is difficult and has been subject to many revisions, but molecular genetic data do support monophyly of ''Kurixalus''. These frogs are distributed from Himalayan front ranges of eastern India southward and eastward to Cambodia, Vietnam, southern China, Taiwan, and the Ryukyu Islands. Species , the following 19 species are recognized: * '' Kurixalus absconditus'' Mediyansyah, Hamidy, Munir, and Matsui, 2019 – Piasak-frilled swamp treefrog * '' Kurixalus appendiculatus'' (Günther, 1858) – frilled tree frog, rough-armed tree frog, or Southeast Asian tree frog * '' Kurixalus baliogaster'' (Inger, Orlov, and Darevsky, 1999) – belly-spotted frog * '' Kurixalus banaensis'' (Bourret, 1939) – Bana bubble-nest frog * '' Kurixalus berylliniris'' Wu, Huang, Tsai, Li, Jhang, and Wu, 2016 * ''Kurixalus bisacculus'' (Taylor, 1962) − Taylor's treefrog * '' Kurixalus chaseni'' (Smith, 1924 ...

IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Oophagous
Oophagy ( ) sometimes ovophagy, literally "egg eating", is the practice of embryos feeding on eggs produced by the ovary while still inside the mother's uterus. The word oophagy is formed from the classical Greek (, "egg") and classical Greek (, "to eat"). In contrast, adelphophagy is the cannibalism of a multi-celled embryo. Oophagy is thought to occur in all sharks in the order Lamniformes and has been recorded in the bigeye thresher (''Alopias superciliosus''), the pelagic thresher (''A. pelagicus''), the shortfin mako (''Isurus oxyrinchus'') and the porbeagle (''Lamna nasus'') among others. It also occurs in the tawny nurse shark (''Nebrius ferrugineus''), and in the family Pseudotriakidae. This practice may lead to larger embryos or prepare the embryo for a predatory lifestyle. There are variations in the extent of oophagy among the different shark species. The grey nurse shark (''Carcharias taurus'') practices intrauterine cannibalism, the first developed embryo consuming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyathea Spinulosa
''Alsophila spinulosa'', also known as the flying spider-monkey tree fern, is a species of tree fern in the family Cyatheaceae The Cyatheaceae are a family of ferns, the scaly tree ferns, one of eight families in the order Cyatheales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family may defined much more broadly (Cyatheaceae .... Description The trunk of this species can grow to a height of 5 m or more. The stipes are persistent, spiny and purplish towards the base, and covered in brown shiny scales. Fronds are 1–3 m long and three-limbed. The sori, producing the spores, are large and round. Like many tree ferns, it features a "skirt" of dead leaves that do not drop off the crown and form a barrier for parasitic climbing plants. Distribution and habitat ''A. spinulosa'' occurs in humus soils in shadowed forest locations, and is widely distributed across Asia including China, Nepal, India, Burma, Myanmar, and Japan.

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 ...

Arboreal Locomotion
Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on narrow branches, mov ...

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 ...

Hai'an Range
The Coastal Mountain Range, also known as the Hai'an Range (), is a mountain range situated on the eastern coast of the island of Taiwan, and spans the border between Hualien and Taitung Counties. The Coastal Mountain Range is the northern portion of the Luzon Arc but do not present current volcanic activity. Its geology is mainly composed of a Miocene volcanic basement covered by a thick (ca.4-6km) sedimentary pile of deep to shallow marine clastic deposits mostly derived from the adjacent Central Range mountains to the west. The Huadong Valley, the result of the collision of two tectonic plates, is at the west end of the range, and the tallest peak of the range is Xingangshan (新港山), which stands tall. Currently those peaks are still rising with an annual speed of 3 mm. The Hai'an Range is also converging with Central Mountain Range with an average speed of 2.3 cm per year. There are several small basins located around the range, the largest of which is Taiyu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Mountain Range
The Central Mountain Range is the principal mountain range on the island of Taiwan. It runs from the north of the island to the south. Due to this separation, connecting between the west and east is not very convenient. The tallest peak of the range is Xiuguluan Mountain, . Names "Central Range" or "Central Mountain Range" is a calque of the range's Chinese name, the ''Zhōngyāng Shānmài'' or ''Shānmò''. It is also sometimes simply called the Zhongyang or in English. During the Qing Dynasty, the range was known as the , from the Wade-Giles romanization of the Chinese name ''Dàshān'', meaning "Big Mountains". Geography In a broad sense, Central Mountain Range includes its conjoint ranges such as Xueshan Range and Yushan Range; thus the tallest peak of Central Mountain Range in this sense is Yushan (Jade Mountain/Mount Morrison), , and the second tallest peak is Xueshan (Snow Mountain), .
