Species loss in food-web networks

这项研究将提供关键的知识，物种损失如何影响生态系统功能的物种贫乏的北方生态系统。目前尚不清楚北方生态系统物种丧失的后果是否与较温暖地区相似，或者北极物种和群落是否具有可能加剧物种丧失后果的独特性质。这项研究将扩大我的NSERC发现补助金的物种损失在食物网网络，包括物种贫乏的北方社区从丘吉尔，马尼托巴省，Resolute湾，努纳武特和伊卡卢伊特，努纳武特，以确定物种贫乏的北方生态系统物种损失的潜在后果。

This research will provide critical knowledge on how species loss affects ecosystem functioning in species-poor Northern ecosystems. Currently it is unknown whether the consequences of species-loss in Northern ecosystems will be similar to warmer regions or whether there are unique properties associated with Arctic species and communities which may exacerbate the consequences of species loss. This research will extend my NSERC Discovery Grant on species loss in food-web networks to include species-poor Northern communities from Churchill, Manitoba, Resolute Bay, Nunavut, and Iqaluit, Nunavut to determine the potential consequences of species loss in species-poor Northern ecosystems.
