The present review provides a compilation of the published data on the phenomena of
multiple mating by females and multiple paternity in their litters in 48 rodent species with …

Selective pressure from parasites is thought to maintain the polymorphism of major

Mating system and philopatry influence the genetic structure of a social group in mammals.
Brandt's vole (Lasiopodomys brandtii) lives in social groups year-round and has male …

Effective population size (Ne) is important because it describes how evolutionary forces will
affect a population. The effect of multiple sires per female on Ne has been the subject of …

Mating behaviour is an important component of species' life histories. Knowledge of natural
patterns of mating can lead also to more effective management strategies for populations of …

Climate-related changes have a severe impact on wetland ecosystems and pose a serious
challenge for wetland-dependent animals as their preferred habitats decline, lose spatial …

Across species, there is usually a positive relationship between sperm competition level and
