Leipzig Botanical Garden
The Leipzig Botanical Garden (german: Leipziger Botanische Gärten, Botanischer Garten der Universität Leipzig) is a 3.5-hectare botanical garden maintained by the University of Leipzig and is located at Linnéstraße 1, Leipzig, Saxony, Germany. It is the oldest botanical garden in Germany and among the oldest in the world, and open daily without charge. Leipzig's botanical garden dates back to at least 1542, although the garden has moved several times. They were created shortly after the university's reform in 1539, when Maurice, Elector of Saxony donated the Dominican monastery of St. Pauli. Its former monastery garden, on the north side of the Paulinerkirche, was reworked as a ''hortus medicus'' by May 1543. This first garden was destroyed in the Thirty Years' War, and in 1648 the university acquired a new site (now Grimmaische Street) where in 1653 it created its second garden. In 1807 the garden was moved to the grounds of the Pleißemühlgraben, where greenhouses were co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation ...

Amphibians Described In 1921
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frogs Of South America
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 is an ex ...

Epipedobates
''Epipedobates'' is a genus of poison dart frogs native to northern South America (Colombia and Ecuador) west of the Andes, including the western slopes. Common name phantasmal poison frogs has been suggested for the genus. Taxonomy ''Epipedobates'' was erected in 1987 in an attempt to split dendrobatids into monophyletic genera, accommodating species that had until then been placed in ''Phyllobates''. In the major revision of poison dart frogs in 2006, most of the species formerly placed in ''Epipedobates'' were then transferred to ''Ameerega'', leaving behind just five species. With description of new species, the species count had increased to seven by early 2015. Description Dorsal Dorsal (from Latin ''dorsum'' ‘back’) may refer to: * Dorsal (anatomy), an anatomical term of location referring to the back or upper side of an organism or parts of an organism * Dorsal, positioned on top of an aircraft's fuselage * Dorsal c ... colouration is cryptic, brown.

IUCN
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Epibatidine
Epibatidine is a chlorinated alkaloid that is secreted by the Ecuadoran frog '' Epipedobates anthonyi'' and poison dart frogs from the Ameerega genus. It was discovered by John W. Daly in 1974, but its structure was not fully elucidated until 1992. Whether epibatidine is the first observed example of a chlorinated alkaloid remains controversial, due to challenges in conclusively identifying the compound from the limited samples collected by Daly. By the time that high-resolution spectrometry was used in 1991, there remained less than one milligram of extract from Daly's samples, raising concerns about possible contamination. Samples from other batches of the same species of frog failed to yield epibatidine. Epibatidine is toxic. Its toxicity stems from its ability to interact with nicotinic and muscarinic acetylcholine receptors. These receptors are involved in the transmission of painful sensations, and in movement, among other functions. Epibatidine then causes numbness ...

Gladwyn Kingsley Noble
Gladwyn Kingsley Noble (September 20, 1894 – December 9, 1940) was an American zoologist who served as the head curator for the Department of Herpetology and the Department of Experimental Biology at the American Museum of Natural History. Noble received bachelor's and master's degrees from Harvard University in 1917 and 1918, respectively, and a Ph.D. from Columbia University in 1922. He joined the herpetology department in 1922 as a research assistant and assistant curator in 1917, and became the chairman of the department in 1924. He later formed the Department of Experimental Biology in 1928, and served as the chairman of both departments until his death on December 9, 1940, from a streptococcal throat infection. Noble is the taxon author of 20 new species of reptiles. A species of lizard, ''List of Anolis lizards, Anolis noblei'', is named in his honor. Also, a subspecies of lizard, ''Sphaerodactylus darlingtoni, Sphaerodactylus darlingtoni noblei'', is named in his honor. ...
