Lake Ontario's condition has fluctuated since European settlement, and our understanding
of the linkages between observed ecosystem shifts and stressors is improving. Changes in …

Upon its initial publication more than fifteen years ago, this book broke new ground with its
comprehensive coverage of the biology and ecology, distribution and dispersal …

Using historical (1970) and more recent (1996) Lake Erie plankton and trophic status data,
we developed a Planktonic Index of Biotic Integrity (P-IBI) to measure changes in lake …

There is much concern that filter‐feeding Asian carp will invade the Laurentian Great Lakes
and deplete crucial plankton resources. We developed bioenergetic models, using …

In large lakes, temporal variability is compounded by strong spatial variability associated
with mesoscale physical processes such as upwelling and basin-scale circulation. Here we …

In recent decades, three important events have likely played a role in changing the water
temperature and clarity of the Laurentian Great Lakes: 1) warmer climate, 2) reduced …

Zooplankton play key top-down and bottom-up regulatory roles in aquatic food webs, and
are also ecologically indicative in marine ecosystems. However, there are relatively limited …

In large lake systems the nearshore habitat is an intermediate zone between the shoreline
and offshore, is an important nursery for larval fish, and is highlighted as an area in need of …

Abstract The Lake Ontario cisco Coregonus artedi population declined in the 20th century,
and restoration of this species is a management objective. Management tools to restore …

Development and use of biological indicators to monitor the status and trends of aquatic
ecosystems such as streams and rivers (Karr 1981, 1991; Wichert 1995; Wichert and …
