Raherisoa and Rainer Dolch Abstract The diversity of amphibians before and rainforest habitat showed a non-significant 10.1% after low-level forest exploitation in An’Ala forest in decrease in abundance after logging. It appears therefore central-eastern Madagascar was compared over the that amphibians are relatively resilient to a low-level course of 4 years. Neither abundance nor diversity of of forest exploitation and their diversity is apparently not amphibians generally were significantly affected by affected, at least in the short-term. This and other studies low-level selective logging, although the abundance of have, however, shown that logging commonly results individual species differed. Mantelline anurans were in a shift in species composition, with species typical of the most sensitive, in contrast to the tree frogs of the pristine rainforests being replaced by species adapted to subfamily Boophinae (Mantellidae) and Cophylinae secondary habitats.

With more than 250 species, the Mantellidae is the most species-rich family of frogs in Madagascar. These frogs are highly diversified in morphology, ecology and natural history. Based on a molecular phylogeny of 248 mantellids, we here examine the distribution of three characters reflecting the diversity of eye colouration and two characters of head colouration along the mantellid tree, and their correlation with the general ecology and habitat use of these frogs. We use Bayesian stochastic character mapping, character association tests and concentrated changes tests of correlated evolu- tion of these variables. We confirm previously formulated hypotheses of eye colour pattern being significantly correlated with ecology and habits, with three main character associations: many tree frogs of the genus Boophis have a bright col- oured iris, often with annular elements and a blue-coloured iris periphery (sclera); terrestrial leaf-litter dwellers have an iris horizontally divided into an upper light and lower dark part; and diurnal, terrestrial and aposematic Mantella frogs have a uniformly black iris.

BURCII,Editot* Ku1.1: SI.EFANOAND JANICEPAPPAS, Assistant Editoras The publications of the Museum of Zoology, The University of Michigan, consist primarily of two series-the Miscellaneous P~rhlicationsand the Occasional Papers. Both serics were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. Occasionally the Museum publishes contributions outside of thesc series; beginning in 1990 these are titled Special Publications and are numbered. All s~tbmitledmanuscripts to any of the Museum's publications receive external review. The Occasiontrl Papers, begun in 1913, sellie as a mcdium for original studies based prii~cipallyupon the collections in the Museum. They are issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Mi.scelluneous Puhlicutions, initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are publislled separately. It is not intended that they bc grouped into volumes. Each number has a title page and, when necessary, a table of contents.

E-mail: Frank Glaw, [email protected] Abstract Frogs of the subfamily Mantellinae (Amphibia: Anura: Mantellidae) are a species-rich and diverse lineage endemic to the Madagascan region. The major synapomorphy of this clade is a derived reproductive mode including an unusual mating behaviour (loss of strong mating amplexus, egg deposition outside of water) and associated morphological adaptations (evolution of femoral glands, loss of nuptial pads). However, the evolutionary steps towards this unique character complex remain obscure. We here describe a recently discovered new frog, Tsingymantis antitra gen. nov., sp. nov. from the moderately dry karstic massif Tsingy de Ankarana in northern Madagascar. The new species is not referable to any existing genus or species groups. A phylogenetic analysis, based on DNA sequences of four mitochondrial genes (12S and 16S rRNA, tRNAVal, cytochrome b) and one nuclear gene (rhodopsin) placed Tsingymantis without significant support as sister taxon of the Mantellinae which was found to be a well-defined monophyletic group (100% Bayesian and 99% bootstrap support). The position of Tsingymantis as the most basal clade of the Mantellinae is in agreement with several morphological and osteological characters, suggesting that this subfamily including Tsingymantis may be a monophyletic group whereas the Boophinae could represent the most basal clade of the Mantellidae.

  • Reptiles & Amphibians of Kirindy
    REPTILES & AMPHIBIANS OF KIRINDY KIRINDY FOREST is a dry deciduous forest covering about 12,000 ha and is managed by the Centre National de Formation, dʹEtudes et de Recherche en Environnement et Foresterie (CNFEREF). Dry deciduous forests are among the world’s most threatened ecosystems, and in Madagascar they have been reduced to 3 per cent of their original extent. Located in Central Menabe, Kirindy forms part of a conservation priority area and contains several locally endemic animal and plant species. Kirindy supports seven species of lemur and Madagascarʹs largest predator, the fossa. Kirindy’s plants are equally notable and include two species of baobab, as well as the Malagasy endemic hazomalany tree (Hazomalania voyroni). Ninety‐nine per cent of Madagascar’s known amphibians and 95% of Madagascar’s reptiles are endemic. Kirindy Forest has around 50 species of reptiles, including 7 species of chameleons and 11 species of snakes. This guide describes the common amphibians and reptiles that you are likely to see during your stay in Kirindy forest and gives some field notes to help towards their identification. The guide is specifically for use on TBA’s educational courses and not for commercial purposes. This guide would not have been possible without the photos and expertise of Marius Burger. Please note this guide is a work in progress. Further contributions of new photos, ids and descriptions to this guide are appreciated. This document was developed during Tropical Biology Association field courses in Kirindy. It was written by Rosie Trevelyan and designed by Brigid Barry, Bonnie Metherell and Monica Frisch.

Actually, rhacophorids are only distinguished from other ranids by the presence of an intercalary element between ultimate and penultimate phalanges of fingers and toes, and by generally (but not consistently) more arboreal habits. Based on the synapomorphies identified (e.g., presence of a bony sternal style), Laurent (1986), Dubois (1992) and Blommers-Schlösser (1993) proposed to include the Rhacophoridae as subfamily Rhacophorinae in the family Ranidae. However, the proposal of Blommers-Schlösser (1993) (i. e. the definition of the family Ranidae as group contain- ing almost all ranoid taxa with an ossified sternal style) is all but generally accepted by herpetologists. Most authors continue considering the Rhacophoridae as separate family (e.g., Frost 1985), a view also shared by internet databases (as the Amphibian Species of the World database, Amphibiaweb, Tree of life, Genbank; as of 10 November 2000). Furthermore, new names such as "fanged ifrogs" (Emerson & Ward 1998, Emerson et al. 2000a) and "boophids" (Richards et al. 2000) have been used to address ranoid subclades, without a nomenclatural formalization of these groups. In the last few years, numerous new results on Old World treefrog phylogeny have been published, several of them referring to the taxa endemic to Madagascar.

  • The Advertisement Call of the Relict Frog Tsingymantis Antitra from Madagascar
    SPIXIANA 36 1 143-148 München, September 2013 ISSN 0341-8391 The advertisement call of the relict frog Tsingymantis antitra from Madagascar (Anura, Mantellidae) Andolalao Rakotoarison, Jörn Köhler, Frank Glaw & Miguel Vences Rakotoarison, A., Köhler, J., Glaw, F. & Vences, M. 2013. The advertisement call of the relict frog Tsingymantis antitra from Madagascar (Anura, Mantellidae). Spixiana 36 (1): 143-148. Tsingymantis is a monotypic relict lineage of mantellid frogs that inhabits an eroded limestone formation in the north of Madagascar. Herein we describe the formerly unknown advertisement call and provide information on morphological characters of two male voucher specimens. The call consists of a series of very short unpulsed notes repeated at regular intervals. It is not very intense and audible for humans only at a distance of less than around 10 metres from the calling male. We provide the first evidence for the presence of inconspicuous but clearly recogniz- able nuptial pads in reproductively active males and confirm the absence of femo- ral glands.
