Pathways to semelparity versus early maturity in animals and plants

该项目旨在解决生活史进化和生态学中一个重要但尚未解决的问题-哪些机制和限制导致半熟（繁殖一次，这是罕见的），以及哪些导致动物和植物的快速生活史（早期繁殖，这是常见的）。理论预测，两者都可能是对成年死亡时间表的适应。了解为什么男性和女性有semelparous或快速的生活史策略是至关重要的预测收获和受威胁的物种生存的压力下，气候变化，干旱，捕食者和疾病杀死成年人。预期的项目成果包括提高能力，以解决包括单胎物种在内的受威胁动植物减少的因素。

The project aims to resolve an important but unresolved question in life history evolution and ecology- which mechanisms and constraints lead to semelparity (breeding once, which is rare), and which lead to fast life history (breeding early, which is common) in animals and plants. Theory predicts that both may be adaptations to schedules of adult death. Understanding why males and females have either semelparous or fast life history strategies is crucial to predicting survival of harvested and threatened species under pressure from climate change, drought, predators, and diseases that kill adults. Expected project outcomes include improved ability to address agents of decline of threatened animals and plants including semelparous species.
