The results suggest that in Madagascar the spatial pattern of amphibian richness and endemism must be revisited, and current habitat destruction may be affecting more species than previously thought, in amphibians as well as in other animal groups.
Madagascar as a model region of species diversification.
Sorting out Lalos: description of new species and additional taxonomic data on megophryid frogs from northern Indochina (genus Leptolalax, Megophryidae, Anura)
Analysis of diagnostic characters in adult Leptolalax and results of molecular analysis are presented.
DNA barcoding Madagascar's amphibian fauna
We provide a DNA barcoding survey of Malagasy amphibians, including 251 of the 292 nominal species known to date, by complementing previous data with 280 newly determined barcoding sequence fragments…

The locations of six positively correlated centers of SR and endemism that can neither be explained by stochastic models such as elevational or latitudinal mid-domain effect, nor by low-elevation river catchments support a key role of mountainous areas for speciation of these anurans, although it cannot exclude an influence of habitat loss due to human impact.
Speciation in little: the role of range and body size in the diversification of Malagasy mantellid frogs
A testable hypothesis is defined under which small body sizes result in limited dispersal capabilities and low physiological tolerances, causing smaller and more strongly fragmented ranges and can be thought to facilitate reproductive isolation and thus favor speciation.

It is suggested that lower dispersal ability also curbs colonization of new areas, decelerating diversification in weak dispersers and may explain inconsistent previous results on the correlation of body size and speciation rate.
Disentangling composite colour patterns in a poison frog species
A phylogenetic approach was performed to infer whether variation in conspicuous colour-patterns of a poison frog has evolved neutrally or under selection, and found noncorrelation of all displayed factors with the marker may indicate the evolution of colour patterns on dorsum and flanks under selection.
Why colour in subterranean vertebrates? Exploring the evolution of colour patterns in caecilian amphibians
It is found that certain colour pattern elements in caecilians can be explained based on characteristics concerning above‐ground movement and the results suggest that very little exposure to daylight is required to evolve and maintain a varied array of colour patterns in animal skin.
