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.

该项目旨在解决生命史进化和生态学中一个重要但尚未解决的问题——哪些机制和约束导致了动植物的半胚性（繁殖一次，这是罕见的），哪些导致了动植物的快速生活史（繁殖早期，这是常见的）。理论预测两者都可能是对成人死亡时间表的适应。了解为什么雄性和雌性有半产或快速的生活史策略，对于预测收获和受威胁物种在气候变化、干旱、捕食者和杀死成虫的疾病的压力下的生存至关重要。预期的项目成果包括提高解决包括半产物种在内的濒危动植物数量减少的能力。
