Queen's researchers show that dispersal of zooplankton from nearby ponds can help maintain ecosystem function after disturbance.

Celia SymonsCelia Symons and Shelley Arnott conducted experiments in Churchill, Manitoba to investigate the effects of increased salinity and nutrient concentrations on pond ecosystems.   They found that nutrient and salt loading degraded ecosystem function, but the dispersal of species from nearby lakes recovered ecosystem function to undisturbed levels. This highlights the role that habitat connectivity and regional diversity will play in maintaining ecosystem function.
