My African biodiversity work has mainly been on small mammals taxonomy in the present and in the past. Morphological evolution and small mammals communities studies. My main areas of interest are mountains rodent and shrews of west-central Africa (Mt Nimba, Cameroon Volcanic Line) and eastern african savannas.
Deforestation by using fires is terrible for small mammals biodiversity especially for gallery forests in savannas environments. In Oku Mount small mammals are now eaten after the disappearance of large mammals, the unique mountain forest is no more regenerationg and is over grazed by domestic cattle. In Mt Nimba , iron mining activities destroy hectares of edaphic savannas and refuge for endemic bats.
