Abstract
Ecological history of Lake Ontario.
Description
Lake Ontario’s ecosystem has been impacted by
urban sprawl, chemical pollutants, agricultural intensification, land use changes, climate change effects, habitat loss and non‐native species. We present a synthesis of long‐term information to
reconstruct past stressor impacts, remediation and trajectories of current changes. Paleolimnological and long‐term monitoring studies, particularly those using diatoms (above), reveal long‐term changes, providing a rich understanding of multiple
stressor effects on primary production including climate‐driven change in lake ecosystems. In this poster we present preliminary analyses from a sedimentary core analysis (above) and monitoring data from recent decades. Approximate temporal zones were derived using cluster analysis of the
sedimentary assemblages. Primary goals of this investigation are to support management of the lake through a retrospective of stressor impacts.
