The question arises as to the origin and phylogenetic significance of these glands. A molecular phylogeny based on 3601 nucleotide DNA sequences of three mitochondrial and two nuclear genes of 30 mantellid species provided strong support for monophyly of the included mantellines, all characterized by enlarged femoral gland clusters, as well as for those with gland clusters of coordinated central arrangement of secretion ducts. However, the phylogeny also strongly supported the hypothesis of convergent evolution of structurally similar glands in unrelated frogs (Indirana, Petropedetes), and several trends of convergent evolution of gland structure within mantellines. We studied the light microscopic structure of the femoral glands in a representative array of 18 mantellid species. Males of all species of the subfamily Mantellinae were characterized by clusters of distinct single glands. Each was structurally similar to an enlarged granular gland and secreted independently, probably through a single duct. By contrast, the largely semi-aquatic frogs in the genus Mantidactylus had a specialized cluster of glands, in which the secretion ducts led into a macroscopically recognizable central depression. In Boophis opisthodon, a mantellid species of the subfamily Boophinae without externally recognizable femoral glands, we observed a large number of enlarged granular glands of various sizes in the ventral skin of the shank. This observation is consistent with the hypothesis that the large and more uniform organs of mantellines are derived granular glands.</dcterms:abstract> <dc:creator>Glaw, Frank</dc:creator> <dcterms:title>Molecular systematics of mantelline frogs from Madagascar and the evolution of their femoral glands</dcterms:title> <dc:creator>Hoegg, Simone</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/6661"/> <dcterms:issued>2007</dcterms:issued> <dc:contributor>Spinelli Oliveira, Elisabeth</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:28:09Z</dc:date> <dc:contributor>Wahl-Boos, Gabriele</dc:contributor> </rdf:Description> </rdf:RDF>
