Dollman's tree mouse
Dollman's tree mouse (''Prionomys batesi'') is a poorly understood climbing mouse from Central Africa. It is unique enough that it has been placed in a genus of its own, ''Prionomys'', since its discovery in 1910.
==Distribution and habitat==
Dollman's tree mouse has only been recorded in four localities in three countries. These are Bitye and Obala in Cameroon, La Maboké in Central African Republic, and Odzala in Republic of the Congo. In total only 23 specimens are known to be present in museums throughout the world (Denys et al., 2006).
Denys et al. (2006) indicate that ''Prionomys'' has a unique association with forest-savannah mosaics in central Africa. During interglacial periods, this region has undergone varying degrees of wet and dry periods. Savannah expands during dry periods and forest expands during wet periods, but there are small scale shifts in which regions are dry or wet. ''Prionomys'' appears to be associated with forest habitat on the edge of savannah patches. In particular, the species occurs as forest is recolonizing areas that were once savannah. Thus it is thought to be associated with younger, earlier successional forest but is no longer present in mature, late successional forest.
