Infanticide as a male reproductive strategy has a nutritive risk effect in brown bears
Behavioural strategies to reduce predation risk can incur costs, which are often referred to as risk effects. A common strategy to avoid predation is spatio-temporal avoidance of predators, in which prey typically trade optimal resources for safety. Analogous with predator-prey theory, risk effects should also arise in species with sexually selected infanticide (SSI), in which females with depe...
متن کاملTerritoriality and male reproductive success in arctic ground squirrels
Although territorial defense is a common form of reproductive competition among male vertebrates, the exact reproductive consequences of this behavior are often poorly understood. To explore relationships between territoriality and reproductive success in a nongroup-living mammal, we quantified patterns of space use, mating success, and fertilization success for males in a free-living populatio...
متن کاملA test of male infanticide as a reproductive tactic in a cichlid fish
Infanticide and offspring cannibalism are taxonomically widespread phenomena. In some group-living species, a new dominant individual taking over a group can benefit from infanticide if doing so induces potential mates to become reproductively available sooner. Despite widespread observations of infanticide (i.e. egg cannibalism) among fishes, no study has investigated whether egg cannibalism o...

متن کاملInfanticide and reproductive restraint in a polygynous social mammal.
Alpha male chacma baboons experience uncontested access to individual estrus females. Consequently, alpha male paternity certainty is high and underpins significant levels of infanticide by immigrant males that, in turn, has selected for male defense of infants. There is also, however, a high probability that alpha males will be absent during the period when their own offspring are vulnerable, ...
