Aquatic Food Webs
Food web structure of lakes has been an area of research at Harkness for several years. Read more here on the background of the work.
Biostructure of Lake Food Webs in Algonquin Park
The mobility of top predators in aquatic food webs can result in the integration of different food webs as predators move between spatially distinct areas. The level of integration among food webs can be a function of the size of lakes. In small lakes, a top predator like lake trout may integrate food webs (pelagic, benthic littoral) more than in larger lakes with spatially separate food webs.
Species invasions can disrupt predator based linkage of food web productivity by 'capturing' specific areas or elements of food webs. A large scale research program focusing on lake trout lakes with and without bass is a new focus for work out of Harkness.
