Mantella
''Mantella'' (also known as golden frogs or Malagasy poison frogs) are a prominent genus of aposematic frogs in the family Mantellidae, endemic to the island of Madagascar. Members of ''Mantella'' are diurnal and terrestrial, with bright aposematic coloration or cryptic markings. Natural history ''Mantella'' are an example of convergent evolution—the independent evolution of a similar trait with species of a different lineage—with the Latin American family Dendrobatidae in size, appearance, and some behavioral characteristics. During the description of the first specimens from 1866 to 1872, Alfred Grandidier described both the brown mantella (''Mantella betsileo'') and Malagasy mantella (''Mantella madagascariensis'') and placed them within the genus ''Dendrobates'' based on their close resemblance. This placement was heavily debated until 1882, when George Albert Boulenger created the genus ''Mantella'' after describing both Cowan's mantella (''Mantella cowanii'') and ...

Mantella Baroni
''Mantella baroni'' (often known by its common names, such as Baron's mantella, the variegated golden frog, or the Madagascar poison frog) is a species of small poisonous frog in the family Mantellidae. The species was first formally described by George Albert Boulenger in 1888, who penned the species' binomial after Richard Baron, an English botanist and missionary to Madagascar, who collected and studied the species. Distribution, habitat, and conservation status Like other species in Mantellidae, this taxon is endemic to Madagascar. This family is estimated to have colonized the island of Madagascar 76–87 million years ago, evolving in insular seclusion, and adaptively radiating in geographic range and number of species on the island. Mantellidae are phylogenetically related to Asiatic frogs, and therefore probably represent a dispersal event from Asia. This is one of approximately 220 frog species (including 15 in ''Mantella'') endemic only to Madagascar. It has a mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mantella Madagascariensis
''Mantella madagascariensis'', common names Malagasy painted mantella, Madagascan mantella, Madagascar golden frog, Malagasy mantella and painted mantella, is a species of frog in the family Mantellidae. Distribution This species is endemic to Madagascar. It is present in the East-central Madagascar in upland locations from near Niagarakely south to Ranomafana, at an elevation of above sea level. It is threatened by habitat loss and it may be threatened by commercial collection. Habitat Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and rivers.Andreone, F. & Glaw, F. 2004.Mantella madagascariensis2006 IUCN Red List of Threatened Species Description ''Mantella madagascariensis'' can reach a body length of in males, of in females. These tiny but stout frogs are rather variable in color and markings, as they are irregularly streaked in black and yellow. Usually they have a blackish body, but the dorsum is co ...

Golden Mantella
The golden mantella (''Mantella aurantiaca'') is a small, terrestrial frog endemic to Madagascar. It has an extremely restricted distribution in three distinct areas centered on the town of Moramanga - Beparasy and Ambohibary Communes, Torotorofotsy Wetland northwest of Andasibe, and in the area of Ambakoana. ''Mantella aurantiaca'' is one of Madagascar's most threatened amphibian species due to its limited distribution in an area under tremendous anthropogenic pressure. It may also be threatened by over-collection for the pet trade. Description The golden mantella is a uniformly yellow, orange, or red frog measuring 20–26 mm. The inner leg displays red flash marks. The tympanum is visible, but small. Brightly colored skin warns predators that the frog is poisonous. It is thought that the brilliant colors exhibited by the golden mantella are an example of aposematism, warning predators of the poisonous nature of the frog. Ecology and behaviour The golden mantella is hig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard Baron (botanist)
Reverend Richard Baron (8 September 1847 – 12 October 1907) was an English missionary and botanist who worked and lived in Madagascar from 1872 to 1907. Baron attended Lancashire College and was ordained 1872 in Kendal. During his mission in Madagascar from 1872 onwards, he travelled extensively and collected a large number of plants; he sent roughly 12,000 specimens to the Royal Botanical Gardens, Kew, and also deposited collections in other herbaria. He may have discovered up to 1000 new plant species. Besides botany, Baron was also interested in geology and collected amphibians. He quickly learned Malagasy language, Malagasy, and published the first Malagasy-language textbooks on plants and geology. Together with James Sibree, Jr., another missionary, he edited the English-language journal ''Antananarivo Annual''. His ''Compendium des plantes malgaches'' was the first summary of the vascular plant species known from Madagascar. It was compiled in several volumes from 1900 t ...

Mantellidae
The Mantellidae are a family of the order Anura. These frogs are endemic to the islands of Madagascar and Mayotte. Systematics The family Mantellidae is composed of three extremely ecologically diverse groups of frogs, divided into three subfamilies: the Mantellinae Laurent, 1946 are typically terrestrial or semi-aquatic frogs; the Laliostominae Vences & Glaw, 2001 are terrestrial, typically fairly large-sized frogs; and the Boophinae Vences & Glaw, 2001 are arboreal tree frogs. Apart from the genera assigned to the three subfamilies, the placement of '' Tsingymantis'' Glaw, Hoegg & Vences, 2006 is still uncertain. As of 22 September 2022, 237 species are recognized in this family. DNA barcoding research has shown however that more than 100 distinct genetic lineages remain taxonomically undescribed. Evolution and island biogeography The Mantellidae are Madagascar's most diverse frog family. It has been shown that there is a negative correlation between body size ...

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] |
Dendrobatidae
Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the Family (biology), family Dendrobatidae which are native to tropical Central and South America. These species are Diurnality, diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them Aposematism, aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have Crypsis, cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this feature from their diet of ants, mites and termites. However, other species that exhibit cryptic coloration, and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are Threatened species, threatened due to human infrastructure encroaching on their habitats. These amphibians ...

Herpetology
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists and He ...

Alfred Grandidier
Alfred Grandidier (20 December 1836 – 13 September 1921) was a French naturalist and explorer. From a very wealthy family, at the age of 20, he and his brother, Ernest Grandidier (1833–1912), undertook a voyage around the world. At first they were led by the astronomer and physicist Pierre Jules César Janssen (1824–1907), but when Janssen fell sick and had to return to France after about six months, the brothers continued the journey. They visited South America in 1858 and 1859 and in particular the Andes, Peru, Chile, Bolivia, Argentina and Brazil. During this voyage they gathered a significant collection of specimens which were analyzed, in 1860, by Ernest. The two brothers parted ways after this. Ernest Grandidier went to China and collected a vast number of specimens which are now in the Louvre and the Guimet museum. Alfred travelled to India, reaching it in 1863. He had intended to explore the high plateau of Tibet, but was prevented by a severe attack of fever. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
