Ecological characteristics in habitats of two African mole-rat species with different social systems in an area of sympatry: implications for the mole-rat social evolution

Popis výsledku v původním jazyce

African mole-rats (Bathyergidae) are subterranean rodents with diverse social systems, which range from solitary to highly cooperative. The social systems are thought to reflect ecological conditions. We examined ecological characteristics in habitats occupied by two mole-rat species with different social systems in an area of sympatry in the Nyika Plateau, Malawi. Whereas the solitary silvery mole-rat Heliophobius argenteocinereus occurs there in the afromontane grasslands, the social Whyte''s mole-ratFukomys whytei is bound to the Miombo woodlands. The habitat of F.?whytei was characterized by a lower food supply and harder soil. We suppose that the niche segregation of the two species in the Nyika Plateau is due to the inability of the solitary species to survive under the harsh ecological conditions. Absence of F.?whytei in higher altitudes may be due to its less effective thermoregulation, competitive exclusion by H.?argenteocinereus, or other unknown factors. Analysis of availab
