Data from: Sex differences in social focus across the lifecycle in humans
- 负责人：
- 摘要：
- . We analyse the inequality in social investment patterns and suggest that the age- and gender-related differences we find reflect the constraints imposed

- 摘要：
- improvement with age in early life, but decreased with age amongst older birds, providing support for actuarial senescence. However, once again no differences
Data from: Changes in data sharing and data reuse practices and perceptions among scientists worldwide

- 摘要：
- earch scientists as they compare to the 2009/2010 baseline study, and to examine differences in practices and perceptions across age groups, geographic regions
Data from: Interactions between host sex and age of exposure modify the virulence-transmission trade-off

- 摘要：
- ns exhibiting declines in both virulence and transmission with increasing host age. Our results suggest that differences in exploitation potential of males

- 摘要：
- of known individuals ranging in age from 3 to 26 years old. We also explored changes in breeding performance in relation to early-life experience (i.e. whether they wer
Data from: Individual shifts toward safety explain age-related foraging distribution in a gregarious shorebird
- 负责人：
- 摘要：
- ved age-related foraging distribution resulted from 1) spatial differences in mortality or 2) age-related shifts in habitat use. Using multistate capture
Data from: Life history differences in age-dependent expressions of multiple ornaments and behaviors in a lekking bird
- 负责人：
- 摘要：
- hough such variation underpins differences in male competitive abilities and female preference, which are central to sexual selection. In contrast

- 摘要：
- ality of this pattern is unclear, as some studies suggest that it may represent non-adaptive variation or be an artifact of temporal or spatial differences
Data from: Age and sex affect quantitative genetic parameters for dominance rank and aggression in free-living greylag geese

- 摘要：
- t pronounced differences concerned non-genetic components. In particular, parental effects were larger in juveniles of both sexes than in adults. In paired
Data from: Individual heterogeneity determines sex differences in mortality in a monogamous bird with reversed sexual dimorphism

- 摘要：
- reproductive output and wing length as measures of an individual's frailty. We found that sex differences in age-specific mortality were primarily driven
