Effects of climate change on zooplankton community interactions in an Alaskan lake
Abstract Background Ecological communities are organized by interactions among the biota, and between the biota and external environmental drivers that affect the dynamics of individual taxa. Climate change may alter communities in unexpected ways when environmental drivers have complex effects on i...
