Biological invasions, where non-native species are introduced to locations beyond their natural range, are occurring globally with unintended negative impacts to the ecology and economy of the invaded habitat. In order to prevent new invasions, we need to have a better understanding of the way that an introduced species interacts with the new habitat. My Discovery Grant research will focus on the interaction of zooplankton (microscopic aquatic animals) with habitats in the Great Lakes, with a long term goal of preventing new invasions of zooplankton. Over the next 5-year cycle we will see if a combination of physical habitat factors, such as current speed and temperature, are consistently linked to high density populations of zooplankton, and if high density populations are consistently linked to invasion success. This research will allow us to test the hypothesis that invasion success of zooplankton in the Great Lakes can be predicted on a site-specific basis and will provide insight for better prevention programs to protect this valuable ecosystem.

在全球范围内，将非本地物种引入了超出其自然范围的地点的生物入侵，对入侵栖息地的生态和经济产生了意外的负面影响。为了防止新入侵，我们需要更好地了解引入物种与新栖息地相互作用的方式。我的发现赠款研究将重点介绍浮游动物（微观水生动物）与大湖区栖息地的相互作用，其长期目标是防止新入侵浮游动物。在接下来的5年周期中，我们将查看物理栖息地因子（例如当前速度和温度）是否始终与浮游动物的高密度种群相关，以及是否始终将高密度种群与入侵成功联系起来。这项研究将使我们能够测试以下假设：浮游动物在大湖区的入侵成功可以在特定地点进行预测，并将为更好的预防计划提供洞察力，以保护这一宝贵的生态系统。
