Species loss in food-web networks

这项研究将为物种丧失如何影响物种贫乏的北方生态系统的生态系统功能提供关键知识。目前尚不清楚，北方生态系统中物种丧失的后果是否会与较温暖地区相似，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特性。这项研究将扩大我的NSERC关于食物网中物种损失的发现资助，包括来自丘吉尔、马尼托巴、努纳武特的雷索特湾和努纳武特的伊卡鲁特的物种贫乏的北部社区，以确定物种损失在物种贫乏的北部生态系统中的潜在后果。

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.
