Blommersia Angolafa
''Blommersia angolafa'' is a species of frogs in the family Mantellidae. This recently described species is Endemism, endemic to eastern Madagascar. The specific epithet (zoology), specific epithet is derived from the term “angolafa” or “angolafo”, which is the Malagasy language, Malagasy vernacular name used by the Betsimisaraka people for the ''Dypsis'' palm species (mostly for ''Dypsis lastelliana''), whose leaves and prophylls are the habitat for this frog. Description ''Blommersia angolafa'' is a small frog, with a body size of 17–21 mm, enlarged tips on fingers and toes, and without any dark area in the tympanic and frenal region, present in the other ''Blommersia''. ''B. angolafa'' has a rather uniform dorso-lateral colouration, shading from yellowish–light brownish to dark brown, with light-bluish spots on the flanks and light-bluish terminal parts of the fingers and toes. The species also appears to be chromatically sexually dimorphic. In fact, males diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Zahamena Reserve
Zahamena National Park is a national park of Madagascar. Established in 1997, it covers an area of out of a total protected area of . It is part of a UNESCO World Heritage Site, Rainforests of the Atsinanana, inscribed in 2007 and consisting of 13 specific areas located within eight national parks in the eastern part of Madagascar. In 2001, Bird Life International assessed avifauna of 112 species of which 67 species are exclusively endemic to Madagascar. The park is habitat for 112 bird species, 46 reptile species, 62 species of amphibians and 48 species of mammals, including 13 species of lemurs. The ethnic groups inhabiting the area are mostly Betsimisaraka and Sihanak. The most prominent faunal species in the park are: '' Indri indri'' (babakoto), a black lemur with white patches; the Madagascar red owl ''(Tyto soumagnei)'', locally known as vorondolomena; the katsatsaka ('' Paroedura masobe''), a small gecko; the Madagascar serpent eagle (''Eutriorchis astur''), a threaten ...

Amphibians Of Madagascar
The population of amphibians of Madagascar is made up exclusively of frogs. There are 311 named species of frogs on Madagascar, but several hundred have been identified using DNA barcoding and remain to be formally described. Native described species belong to four different families: Hyperoliidae (11 species), Mantellidae (212 species), Microhylidae (86 species) and Ranidae (1 species). Two further species are introduced: the ranid frog ''Hoplobatrachus tigrinus'' and the toad ''Duttaphrynus melanostictus''. Almost all native species are endemic, with the exception of ''Ptychadena mascareniensis''. 85 species are threatened with extinction, nine of which are considered by the IUCN as critically endangered. Their numbers are largely affected by major alterations of habitat due to deforestation and the expansion of paddy fields and villages, and to a lesser extent, by illegal international trade.

Lentic
A lake ecosystem or lacustrine ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (non-living) physical and chemical interactions. Lake ecosystems are a prime example of lentic ecosystems (''lentic'' refers to stationary or relatively still freshwater, from the Latin ''lentus'', which means "sluggish"), which include ponds, lakes and wetlands, and much of this article applies to lentic ecosystems in general. Lentic ecosystems can be compared with lotic ecosystems, which involve flowing terrestrial waters such as rivers and streams. Together, these two ecosystems are examples of freshwater ecosystems. Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1642 m. The general distinction between pools/ponds and lakes is vague, but Brown states that ponds and pools have their entire bottom surfaces exposed to light, while lakes do not. In addition, some lakes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apomorphy
In phylogenetics, an apomorphy (or derived trait) is a novel Phenotypic trait, character or character state that has evolution, evolved from its ancestral form (or Plesiomorphy and symplesiomorphy, plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxon, taxa and is therefore Hypothesis#Scientific hypothesis, hypothesized to have evolved in their most recent common ancestor. ) In cladistics, synapomorphy implies Homology (biology), homology. Examples of apomorphy are the presence of Terrestrial locomotion#Posture, erect gait, fur, Evolution of mammalian auditory ossicles, the evolution of three middle ear bones, and mammary glands in mammals but not in other vertebrate animals such as amphibians or reptiles, which have retained their ancestral traits of a Terrestrial locomotion#Posture, sprawling gait and lack of fur. Thus, these derived traits are also synapomorphies of mammals in general as they are not shared by other vertebrate animals. Etymology The word ...

Dypsis Lastelliana
''Dypsis'' is a genus of flowering plants in the family Arecaceae. They are slender, evergreen palms with yellow flowers carried in panicles amongst the pinnate leaves. Many ''Dypsis'' species have aerial branching (above the main trunk), a rare growth habit among palms. Some have marcescent leaves that remain attached after death and trap litter for nutrients. Several species previously placed here have been returned to the restored genera '' Chrysalidocarpus'' (including the type species ''Chrysalidocarpus lutescens'') and '' Vonitra''. Etymology The etymology is obscure but may be related to the Greek ' ‘I dive’ or ' ‘diver’. The species are native to Tanzania, Madagascar, and various islands in the Indian Ocean (Mauritius and Comoros). A few are naturalized in other regions, especially in the Caribbean. Species ''Plants of the World Online'' currently (July 2024) includes: # '' Dypsis ambilaensis'' # '' Dypsis andapae'' # '' Dypsis andilamenensis'' # '' Dypsi ...

Sexual Selection In Frogs
Sexual selection in amphibians involves sexual selection processes in amphibians, including frogs, salamanders and newts. Prolonged breeders, the majority of frog species, have breeding seasons at regular intervals where male-male competition occurs with males arriving at the waters edge first in large number and producing a wide range of vocalizations, with variations in depth of calls the speed of calls and other complex behaviours to attract mates. The fittest males will have the deepest croaks and the best territories, with females making their mate choices at least partly based on the males depth of croaking. This has led to sexual dimorphism, with females being larger than males in 90% of species, males in 10% and males fighting for groups of females. There is a direct competition between males to win the attention of the females in salamanders and newts, with elaborate courtship displays to keep the females attention long enough to get her interested in choosing him to mat ...

Phytotelma
Phytotelma (plural phytotelmata) is a small water-filled cavity in a terrestrial plant. The water accumulated within these plants may serve as the habitat for associated fauna and flora. A rich literature in German summarised by Thienemann (1954) developed many aspects of phytotelm biology. Reviews of the subject by Kitching (1971) and Maguire (1971) introduced the concept of phytotelmata to English-speaking readers. A multi-authored book edited by Frank and Lounibos (1983)Frank, J.H. and Lounibos, L.P. (1983) ''Phytotelmata: Terrestrial plants as hosts for aquatic insect communities'', Plexus Press. dealt in 11 chapters with classification of phytotelmata, and with phytotelmata provided by bamboo internodes, banana leaf axils, bromeliad leaf axils, '' Nepenthes'' pitchers, '' Sarracenia'' pitchers, tree holes, and '' Heliconia'' flower bracts and leaf rolls. A classification of phytotelmata by Kitching (2000) recognizes five principal types: bromeliad tanks, certain car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Masoala Peninsula
Masoala National Park, in northeast Madagascar, is the largest of the island's protected areas. Most of the park is situated in Sava Region and a part in Analanjirofo. Created in 1997, the park protects 2,300 square kilometres of rainforest and 100 square kilometres of marine parks. The Masoala Peninsula is exceptionally diverse due to its large size, and variety of habitats. Altogether, the park protects tropical rainforest, coastal forest, flooded forest, marsh, and mangrove. Three marine parks protect coral reefs and a dazzling array of marine life. Climate This is an exceptionally wet area of Madagascar. The driest part of the year is from September to December. As the park is accessible only by a three-hour boat journey, the cyclone season (January to March) is best avoided. Flora and fauna There are ten lemur species, including the red ruffed lemur, which is native to the peninsula. The island reserve of Nosy Mangabe is one of the best sites in Madagascar to try to gli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
