- rival exposure male-male competition longevity copulation copulation duration copulation latency
- DOI：
- doi:10.5061/dryad.3nv8n
- 摘要：
- in female mating biology would be reflected in different costs of pre-copulatory competition between males. We observed that exposure to rival males ea
Data from: Sex differences in senescence: the role of intra-sexual competition in early adulthood

- 摘要：
- in senescence have been hypothesized to arise, because investment in intra-sexual reproductive competition entails costs to somatic maintenance, leaving the sex

- 摘要：
- ropean starling prefers lowland habitats and is an aggressive omnivore. S. vulgaris costs hundreds of millions of dollars in agricultural damage each year (estimate
Data from: Color patterns of closely-related bird species are more divergent at intermediate levels of breeding range sympatry

- 摘要：
- ). This pattern suggests that closely related species incur costs at intermediate levels of sympatry if they exhibit similar color patterns—costs that could inc

- 摘要：
- Parental care is thought to be costly, as it consumes time and energy. Such costs might be reduced in animal parents that raise thei
Data from: Post-copulatory sexual selection allows females to alleviate the fitness costs incurred when mating with senescing males

Data from: Intraspecific competition and inbreeding depression: increased competitive effort by inbred males is costly to outbred opponents

- 摘要：
- A recent theoretical model suggests that intraspecific competition is an important determinant of the severity of inbreeding depression. The reason
