The relative contribution of genetic and environmental factors in determining variation in life-history traits is of central interest to evolutionary biologists, but the physiological mechanisms under
Life history theory attempts to explain why species differ in offspring number and quality, growth rate, and parental effort. I show that unappreciated interactions of these traits in response to age-
Fitness can be profoundly influenced by the age at first reproduction (AFR), but to date the AFR-fitness relationship only has been investigated intraspecifically. Here we investigated the relationshi
The Animal Life History Traits dataset consists of 45 columns, containing data for 432 species and subspecies, and is described in Table 3 of the original publication. The first 29 columns describe th
本数据集源自塞舌尔莺同胞竞争终生后果的研究，对比了竞争环境（多数单独抚育，少数有同胞竞争者）下不同竞争能力后代的即时（早期体重、端粒长度、存活率）和延迟（成年繁殖潜力、寿命）代价，旨在揭示野生系统中同胞竞争的进化意义及个体繁殖策略。 Dryad平台（对应研究标题：Consequences of sibling rivalry vary across life in a passerine bird
