When not to avoid inbreeding.
Avoidance of incestuous matings is widely reported across many animal taxa, and the adaptive value of such behavior is explained through inbreeding depression. However, an old and somewhat neglected theoretical result predicts that inbred matings offer another, positive effect on the inclusive fitness of parents: an individual who mates with a relative will help that relative to spread genes id...
متن کاملMutual Mate Choice: When it Pays Both Sexes to Avoid Inbreeding
Theoretical models of sexual selection predict that both males and females of many species should benefit by selecting their mating partners. However, empirical evidence testing and validating this prediction is scarce. In particular, whereas inbreeding avoidance is expected to induce sexual conflicts, in some cases both partners could benefit by acting in concert and exerting mutual mate choic...
متن کاملBanded mongooses avoid inbreeding when mating with members of the same natal group
Inbreeding and inbreeding avoidance are key factors in the evolution of animal societies, influencing dispersal and reproductive strategies which can affect relatedness structure and helping behaviours. In cooperative breeding systems, individuals typically avoid inbreeding through reproductive restraint and/or dispersing to breed outside their natal group. However, where groups contain multipl...
متن کاملWhen not to copy: female fruit flies use sophisticated public information to avoid mated males
Semen limitation (lack of semen to fertilize all of a female's eggs) imposes high fitness costs to female partners. Females should therefore avoid mating with semen-limited males. This can be achieved by using public information extracted from watching individual males' previous copulating activities. This adaptive preference should be flexible given that semen limitation is temporary. We first...
متن کاملPitfalls to avoid when merging information systems.
When healthcare organizations merge, their goal often is to improve operational efficiencies, with information systems (IS) a common target for cost reduction. These cost reductions usually are achieved by reducing staff, consolidating data centers, establishing standardized systems, and sharing resources throughout the system. During this process, however, several common pitfalls can cause mer...
