Environmental Change and Species Interactions

长期的环境变化通过直接影响繁殖、死亡率和其他人口统计参数来改变物种的丰富度。然而，物种丰富度的变化也受到物种内部和物种间生态相互作用所产生的正反馈和负反馈的影响。在这项研究中，将开发种群动力学的随机模型，以预测物种相互作用如何影响环境变化对物种丰度的影响。在与其他研究人员的合作下，这些模型将被用来将这一理论与来自不同类型生态群落的现有长期数据集相结合。

Long-term environmental changes alter the abundance of species by directly affecting reproduction, mortality, and other demographic parameters. However, changes in species abundances are also affected by positive and negative feedbacks operating through ecological interactions within and among species. In the research stochastic models will be developed for population dynamics to predict how species interactions influence the effects of environmental changes on species abundances. In collaboration with other researchers, these models will then be used to integrate this theory with existing long-term data sets from different types of ecological communities.
