Species loss in food-web networks

这项研究将提供有关物种减少如何影响物种匮乏的北方生态系统的生态系统功能的关键知识。目前尚不清楚北方生态系统物种丧失的后果是否与气候变暖地区相似，也不清楚北极物种和群落是否有可能加剧物种丧失后果的独特性质。这项研究将扩展我的NSERC关于食物网络中物种丧失的发现拨款，将包括来自丘吉尔、马尼托巴省、索鲁特湾、努纳武特和伊卡卢伊特、努纳武特的物种匮乏的北方社区，以确定物种匮乏的北方生态系统中物种丧失的潜在后果。

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.
