Micrixalus
''Micrixalus'' (commonly known as dancing frogs, tropical frogs, and torrent frogs) is a genus of frogs from that are endemic to the Western Ghats in India. They are monotypic within the family Micrixalidae. Before being raised to the family level they were classified as the subfamily Micrixalinae within Ranidae. ''Micrixalus'' frogs, such as '' Micrixalus saxicola'', are popularly known as "dancing frogs" due to their peculiar habit of waving their feet to attract females during the breeding season. Dancing frogs are extremely vulnerable as their habitat is severely threatened. Description The family is characterized by having a pectoral girdle that is firmisternal and tadpoles having a single row of labial teeth. Biju ''et al.'' (2014) list the following characteristic features as common to all species of ''Micrixalus'': Natural history Dancing frogs are found in the vicinity of fast and slow moving perennial streams in the forests of the Western Ghats.

Micrixalus Fuscus
''Micrixalus fuscus'' (dusky torrent frog or brown tropical frog) is a species of small frog found in dense forested hill streams in the Western Ghats of India. '' M. herrei'' was formerly synonymized within this species. Description Males measure and females in snout–vent length. Male ''Micrixalus fuscus'' have a single vocal sac, a white patch on the lower jaw, and a prominent nuptial pad on the first finger. Characteristic for the genus, they display the "foot-flagging" behavior, where males tap their hindfeet and extend it, then stretching it out and shaking the foot at prospective mates and rival males. Male-male combats also involve kicking. Description from G. A. Boulenger's (1890) "Fauna of British India": : Snout pointed, prominent, generally longer than the orbital diameter; canthus rostralis angular: loreal region flat, vertical; nostril halfway between the eye and the tip of the snout; interorbital space as broad as the upper eyelid; tympanum small, indistinct. ...

DNA Analysis
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output. In a medical setting, genetic testing can be used to diagnose or rule out suspected genetic disorders, predict risks for specific conditions, or gain information that can be used to customize medical treatments based on an individual's genetic makeup. Genetic testing can also be used to determine biological relatives, such as a child's biological parentage (genetic mother and father) through DNA paternity testing, or be used to broadly predict an individual's ancestry. Genetic testing of plants and animals can be used for similar reasons as in humans (e.g. to assess relatedness/ancestry or predict/diagnose genetic disorders), to gain information used for selective breed ...

Micrixalus Adonis
''Micrixalus adonis'' is a newly described species of frogs in the family Micrixalidae. It is endemic to the Western Ghats in southern India, restricted to areas between the Palghat Gap and Shencottah Gap. Common name beautiful dancing frog has been proposed for this species, in reference to its vividly rich colouration. Description ''M. adonis'' is within the colloquial ''Micrixalus fuscus'' group, including ''M. fuscus'', ''M. herrei'', ''M. kodayari'', ''M. mallani'', and ''M. nelliyampathi''. The species share similar physical characteristics, including slender bodies, the presence of dorsolateral folds, and among others a V-shaped glandular ridge on the anterior half of the body. While being similar to other species within the ''Micrixalus fuscus'' group, ''M. adonis'' is most noticeably different in the shape of its head, which is rounded laterally. Males measure and females in snout–vent length. Foot-flagging has not been observed in this species, presence of fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Hotspot
A biodiversity hotspot is a ecoregion, biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in ''The Environmentalist'' in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into "Hotspots: Earth's Biologically Richest and Most Endangered Terrestrial Ecoregions" and a paper published in the journal ''Nature'', both in 2000. To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as Endemism, endemics, and it has to have lost at least 70% of its primary vegetation. Globally, 36 zones qualify under this definition. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a high share of those species as endemics. Some of these hots ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Markers
In molecular biology and other fields, a molecular marker is a molecule, sampled from some source, that gives information about its source. For example, DNA is a molecular marker that gives information about the organism from which it was taken. For another example, some proteins can be molecular markers of Alzheimer's disease in a person from which they are taken. Molecular markers may be non-biological. Non-biological markers are often used in environmental studies. Genetic markers In genetics, a molecular marker (identified as genetic marker) is a fragment of DNA that is associated with a certain location within the genome. Molecular markers are used in molecular biology and biotechnology to identify a particular sequence of DNA in a pool of unknown DNA. Types of genetic markers There are many types of genetic markers, each with particular limitations and strengths. Within genetic markers there are three different categories: "First Generation Markers", "Second Generatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ceylon Journal Of Science
The ''Ceylon Journal of Science'' is a peer-reviewed open access scientific journal established in 1924 by the Government of Ceylon. The journal was the result of the merger of '' Annals of the Royal Botanic Gardens'', ''Peradeniya'', '' Spolia Zeylanica'', and '' Bulletin of the Ceylon Fisheries''. The journal had several sections, covering different fields, but now consists of a single quarterly publication. In 1942, the University of Peradeniya took over the publication, and ''Spolia Zeylanica'' reverted to a separate publication. In 1958, sections A, B, and C (together covering botany, zoology, and fishery) merged to form ''Ceylon Journal of Science (Biological Sciences)'' while sections E and F (together covering mathematics, physics, meteorology, and chemistry) merged to form ''Ceylon Journal of Science (Physical Sciences)''. Section D was renamed to '' Ceylon Journal of Medical Science'' in 1965 and is now published by the University of Colombo. Section G (covering anthropol ...
