Regional heterogeneity in lake morphology in Ontario

Lake size and shape are important factors determining the function and structure of lake ecosystems.

Moreover, Lake morphology is important for both biotic and abiotic processes, including species

richness of zooplankton, macrophytes, and fishes. In particular, Ontario has tens of thousands of

natural ecosystems that make up a large part of Canada’s dominant share ofthe Earth’s surface

freshwaters and of global freshwater biodiversity. In addition, fish community (e.g. lake trout, walleye,

smallmouth bass) in these lakes support human uses having both high economic and social values (e.g.

commercial and recreational fishery worth 2 billion dollars annually and subsistence and ceremonial

fisheries, providing 69kg/person annually). Thus, this intern will develop a comprehensive data base

documenting geographical heterogeneity in lake size and shape among 1000 Ontario lakes. This

proposed project link the intern at University of Toronto with Ontario Ministry of Natural Resources to

quantitatively examine how lake size and shape differ across Ontario. Insights from this collaboration…
