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.
The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice.
It is shown that small-sized frogs often emit calls with frequency components in the ultrasound spectrum, although it is unlikely that these high frequencies are of biological relevance for the majority of them, and it is illustrated that detection of upper harmonics depends also on recording distance because higher frequencies are attenuated more strongly.
Multiple overseas dispersal in amphibians

The results provide the strongest evidence so far that overseas dispersal of amphibians exists and is no rare exception, although vicariance certainly retains much of its importance in explaining amphibian biogeography.
Aligning Conservation Priorities Across Taxa in Madagascar with High-Resolution Planning Tools
It is shown, in an analysis of wide taxonomic and geographic breadth and high spatial resolution, that multitaxonomic rather than single-taxon approaches are critical for identifying areas likely to promote the persistence of most species.
Multiple colonization of Madagascar and Socotra by colubrid snakes: evidence from nuclear and mitochondrial gene phylogenies

The discovery of a large monophyletic clade of colubrids endemic to Madagascar indicates a need for taxonomic changes and highlights the potential of the Indian Ocean islands to act as an evolutionary reservoir for lineages that have become extinct in Africa and Asia.
First Large-Scale DNA Barcoding Assessment of Reptiles in the Biodiversity Hotspot of Madagascar, Based on Newly Designed COI Primers
The first comprehensive study targeting the entire reptile fauna of the fourth-largest island in the world, the biodiversity hotspot of Madagascar, and the established library of reference DNA barcodes will facilitate the molecular identification of Madagascan reptiles is presented.
Natural colonization or introduction? Phylogeographical relationships and morphological differentiation of house geckos (Hemidactylus) from Madagascar
Morphological data strongly confirm the occurrence of three Hemidactylus species on Madagascar and demonstrate the presence of a fourth species, H. brooki, on the Mascarenes and Comoros archipelagos and indicates that populations of H.mercatorius in Madagascar have a long history that predates human settlement.
Phylogeny, recombination, and mechanisms of stepwise mitochondrial genome reorganization in mantellid frogs from Madagascar.

The results suggest that recombination activity is not a direct cause of convergent gene rearrangement; rather, homoplasious gene rearranged seems to be mediated by persistence of a copied genomic condition through several lineage splits and subsequent parallel deletions.
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…
