Among non-invasive biological samples, feces offer an important source of DNA and can easily be collected. However, working with fecal DNA from highly vegetarious species such as elephant is more challenging because plant secondary compounds have an inhibitory effect on PCR reactions. Working with forest elephant dung samples, we tested and adapted...

Project
In this project, we study the ecological correlates of colour polymorphism, and in particular of the white colouration, in Afrotropical beetles. We focus especially on species of the genera Goliathus, Mecynorhina, Hegemus, Fornasinius, Augosoma, and on their conservation requirements due to their commercial use. Our study is mainly field-based, and covers such different countries as Cote d'Ivoire, Ghana, Togo, Nigeria, Cameroon, Democratic Republic of Congo, Tanzania and South Sudan. We also focus on the conservation and ecology of Titanus giganteus as for the South-American species is concerned
Project
The objective of the project is to conduct health surveillance and risk assessment for a potential next SARSCoV-2-related pandemic in sub-Saharan Africa linked to bushmeat consumption and trade. Because in the context of the COVID-19 outbreak surveying reservoirs and wildlife trade practices is a prerequisite to efficient health surveillance, our project aims to understand the pathways of infection between animals to humans (reservoirs, cross-species infection, virus evolution and recombination)
Project
The expansion of the bushmeat trade has contributed to the appearance of emerging diseases (zoonotic) by increasing in the possibilities of transfer of pathogens to humans from hosts (wild mammals). The overall objective of our project is to characterize the wildlife and associated pathogens encountered in bushmeat markets through a molecular tracing approach including the exhaustive sequencing of host-pathogen communities and the study of local representations on the risks associated with the consumption of bushmeat.
