Ecological and evolutionary dynamics of habitat selection.

我的研究计划旨在开发和测试能够预测栖息地和栖息地变化对自然种群和生态社区未来影响的理论。为了做到这一点，我们必须了解生态和进化条件，允许一些物种入侵现有的群落，而另一些物种则失败。更广泛地说，物种代表着进化策略，其入侵或抵抗其他物种群落入侵的能力取决于参与的个体数量(密度)以及每个物种的相对比例(策略)。我的团队将使用栖息地选择来探索这种替代策略的入侵潜力。栖息地选择是评估进化策略的合适舞台，因为选择一个栖息地而不是另一个栖息地的价值1，随着密度的下降而贬值，2，取决于其他个体所做的选择。我们的研究将利用三种不同的模型系统。

My research program aims to develop and test theories that can predict the future consequences of habitat and habitat change on natural populations and ecological communities. In order to do so, we must understand the ecological and evolutionary conditions that allow some species to invade existing communities while others fail. More generally, species represent evolutionary strategies whose ability to invade, or resist invasion from, communities with other species depends on how many individuals are involved (density), and the relative proportions (frequency) of each species (strategy). My team will use habitat selection in order to probe the invasion potential of such alternative strategies. Habitat selection is a suitable arena for assessing evolutionary strategies because the value of choosing one habitat over another 1, depreciates with density, and 2, depends on the choices made by other individuals. Our studies will capitalize on three different model systems.
