Research Interests

• Ecology and conservation of amphibians and reptiles in the dry forest of Madagascar (in cooperation with the Durrell Wildlife Conservation Trust) - The natural habitats of Madagascar are being lost at a very high rate, especially the deciduous dry forest in the west of the island which by 1990 was thought to have been reduced to only 3% of its original extent. Menabe Central is one of the largest remaining blocks of dry forest in Madagascar and it therefore represents an important site for biodiversity conservation. Menabe Central is known to support high levels of herpetofauna diversity. we are interested to study the distribution and relative abundance of herp species in Menabe Central and the relationship between habitat characteristics and herp diversity. Furthermore, we will investigate the effects of forest disturbance and fragmentation on herp diversity and further the understanding of the biogeography of key reptile and amphibian species. This study will be vital to the development of a potential monitoring programme that could be used to quantify the long term changes in trends in abundance and/or distribution to help quantify the effects of conservation management on these taxa.
• Patterns of tadpole communities in Madagascar - How species communities are organized is one of the most intriguing questions in community ecology. I am interested in elucidating the factors that influence the distribution and abundance of species, and thus the composition and structure of communities. Furthermore, I am interested how community patterns (e.g., deterministic versus stochastic patterns) change over environmental gradients and geographic scales. Also, I am interested what the interdependencies within communities of some important community parameters (e.g., species composition, species richness, community structure) with others (e.g., trophic structure, morphological partitioning between community members, predator-prey interactions) are. These studies are conducted on larval communities at one dry forest site in Western Madagascar in Madagascar and at two sites in the eastern Madagascan rainforest.
• Tadpole morphology and ecology - In the majority of Madagascan anurans, information on morphology and ecology of tadpoles is scarce. However, the knowledge of the morphology and some ecological characters is vital for all studies on larval anurans. I am interested in the morphology of Madagascan tadpoles to study differences between species in an ecological context. For example, the analysis of morphology and ecology of larval stages can help to clearly distinguish between-closely related species that are similar in adult morphology and thus provides information about ecological processes (e.g., interspecific competition) that may occur in the larval but not in the adult stage of an animal. Amphibians of Madagascar - ecology, conservation and systematics.
