Data from: The effects of diet and mating system on reproductive (and post-reproductive) lifespan in a freshwater snail

- 摘要：
- and somatic lifespans, determine the total number of reproductive events, and evaluate how the reproductive rate changes with age. Overall, mated snails
Data from: The effect of dietary restriction on reproduction: a meta-analytic perspective
- 负责人：
- DOI：
- doi:10.5061/dryad.3fc02
- 摘要：
- and no study has quantitatively investigated the effect of DR on reproduction across species. Results: Here we report a comprehensive comparative meta-analysis of the effect

- 摘要：
- on, approximated by a snail’s mean daily growth rate (17.5%). Increased mate availability resulted in a lower diversity of reproductive phenotypes, in particular
Data from: Life-history strategy and behavioral type: risk-tolerance reflects growth rate and energy allocation in ant colonies

- DOI：
- doi:10.5061/dryad.0062v
- 摘要：
- risk tolerance at the colony level. We measure colonies' relative investment in growth rate (new workers produced) compared to reproductive effort (males
Data from: Divergent selection on, but no genetic conflict over, female and male timing and rate of reproduction in a human population
- 负责人：
- DOI：
- doi:10.5061/dryad.4h071
- 摘要：
- to a conflict over trait expression. In mammals, the obligate costs of reproduction are higher for females, making reproductive timing and rate especially liable
Data from: Generation time, net reproductive rate, and growth in stage-age structured populations
- 负责人：
- DOI：
- doi:10.5061/dryad.3m5fc
- 摘要：
- ong with net reproductive rate (R0), has a direct mathematical relationship to and approximates growth rate (r). We use simple examples to show how reproductive timing Tc

- 摘要：
- and subsequent reproduction. Kangaroos are ideal to test predictions about reproductive costs because they may simultaneously lactate and carry a young, and have
Data from: Effects of female reproductive competition on birth rate and reproductive scheduling in a historical human population
- 负责人：
- DOI：
- doi:10.5061/dryad.vv08k
- 摘要：
- Costly reproductive competition among females is predicted to lead to strategies that reduce these costs, such as reproductive schedules
Data from: Size-selective harvesting fosters adaptations in mating behavior and reproductive allocation, affecting sexual selection in fish

- 摘要：
- ge-harvested line showed enhanced reproductive performance, and males of the large-harvested line had the highest egg fertilization rate among all males. These
Data from: Royal Darwinian demons: enforced changes in reproductive efforts do not affect the life expectancy of ant queens

- 摘要：
- in reproductive efforts did not reduce residual life span. Generally, egg-laying rate and life span were positively correlated. Queens of perennial social insects thus se
