Identifying and understanding the mechanisms that shape barriers to dispersal and resulting biogeographic boundaries has been a longstanding, yet challenging, goal in ecology, evolution and biogeography. Characterized by stable, adjacent ranges, without any intervening physical barriers, and limited, if any, range overlap in a narrow contact zone, parapatric species are an interesting system for studying biogeographic boundaries. The geographic ranges of two parapatric frog species, Feirana quadranus and F.
The Asian painted bullfrog Kaloula pulchra is a somewhat cute and comical narrow-mouthed toad from Asia. It has established itself as something of a regular in the international pet trade; it goes by many pseudonyms, but it is perhaps best known by its slightly more accurate trade name of chubby frog. Widespread throughout southern Asia, it is a highly adaptable species that makes the most of encroaching human habitat and is believed to be increasing in population despite its collection for both the food and pet markets.
EMMA C. Tweets by Zootaxa. Cryptic diversity within the Megophrys major species group Amphibia: Megophryidae of the Asian Horned Frogs: Phylogenetic perspectives and a taxonomic revision of South Asian taxa, with descriptions of four new species.
Please take this quick survey to tell us about what happens after you publish a paper. Biochemical Genetics. The relationship between population structure and amount of genetic variation within populations has been investigated in seven species of anurans from Southeast Asia.
There are many published research articles on the amphibians of Borneo and potentially useful literature with broader scope. In this section we recommend some. This is a very subjective list and you may want to expand that list by your own literature reseach.
A potentially deadly pathogen is infecting frogs in Vietnam, but is it causing frog population declines? Many frog populations around the world have suffered dramatic population declines or even been driven to extinction from a disease-causing pathogen known as the amphibian chytrid fungus. We surveyed frogs at a high-elevation forest site in Vietnam where the amphibian chytrid fungus is present and found no evidence of population declines.
Amphibians reach their greatest diversity in the tropics, particularly in the moist and hot environment of tropical rainforest and freshwater swamp forest. Southeast Asia is one of the world's biodiversity hotspots for amphibians, where a remarkable evolutionary explosion has resulted in incredible diversity of form, colour and lifestyle: over species occur in the region. Frogs are to be found in the shallowest puddles, hiding under leaf litter, making their foam nests in streamside vegetation or calling incessantly from treeholes. Frogs reach their greatest evolutionary expression in the diverse family of Asian Tree Frogs Rhacophoridaewhich includes the spectacular Flying Frogs.
By Adam Vaughan. The frog, whose closest relatives are a group of species native to India and Sri Linkais the only member of an ancient lineage dating back millions of years, according to researchers from India and the US. It is unclear whether the species descended from African or Asian frogs.
