| Description
| - The silvery mole-rat Heliophobius argenteocinereus (Bathyergidae) is a solitary subterranean rodent, widely distributed throughout eastern and south-eastern Africa in a variety of habitats. Here, we provide the first data on its biology in a typical natural habitat, the Brachystegia woodland. The population density of mole-rats was low (4.6 ha-1) and its distribution across the study site was random. Contrary to subadults and pups, the sex ratio of adult mole-rats was highly female biased (1:5.75), probably due to the higher mortality of males as a consequence of their mating strategy. Reproduction of Heliophobius is seasonal and pups are born at the beginning of the hot dry season. Burrow systems of the silvery mole-rat were long, highly branched, reticulated and comparable in fractal dimension to systems of social bathyergids. Variability in burrow architecture was related to the body mass of the burrow occupants, soil hardness and food supply when tested together. Burrow systems with a higher fra

- Přestože rypoš stříbřitý patří k rypošům s největším areálem, o jeho populační biologii existuje jen minimum informací. Námi studovaná populace v porostech miomba měla velmi nízkou populační hustotu a distribuce jednotlivých zvířat byla náhodná. Oproti mláďatům byl poměr pohlaví dospělců posunut v neprospěch samců (1:5.75). Za tento jev pravděpodobně může nadzemní aktivita samců během období páření spojená s jejich vyšší predovaností. Podzemní systémy byly dlouhé rozvětvené a srovnatelné svou strukturou se sociálními podzemními druhy. Větší jedinci měli systémy více rozvětvené (cs)
