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.

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.
