Kinship structure and mating system in a solitary subterranean rodent, the silvery mole-rat

Popis výsledku v původním jazyce

The African mole-rats are subterranean rodents that have evolved a wide range of social organisations. Due to some unusual features of their breeding and social systems, much attention has been focussed on social species, with solitary species being virtually ignored. Here, we present the first genetic study on the mating system of any solitary mole-rats, the silvery mole-rat. Microsatellites were used to analyse the mating system and the kinship structure. Isolation by distance between individuals wasapparent in two studied populations, but not in the third, probably as a result of barriers limiting dispersal. Polygyny was found to be a mating system in this population with a strongly female-biased adult sex ratio. Large distances between the burrowsystems of mating partners exclude the possibility of belowground searching for mates, suggesting that the males might seek females above ground. Interestingly, among analysed litters, one multiple-sired litter was found.
