Habitat-Mediated Predator-Prey Interactions in the Eastern Gulf
of Mexico
This research project seeks to identify, test, and balance the bioenergetic
processes that cause differences in growth and condition of gag grouper
as a function of reef habitat characteristics. We use hydroacoustics to
quantify pelagic prey fish at replicate patch reefs, visual censusing
to quantify gag grouper densities, and quantify food consumption of gag.

Implications
of Cercopagis and Bythotrephes to Alewife Recruitment and
Stability of the Lake Michigan Pelagic Food Web
This project proposes to develop a general model from experimental observations
of prey selection and feeding for the invading predatory cercopagid cladocerans Cercopagis pengoi and Bythotrephes longimanus that will
be useful for predicting predatory impact of these cercopagids. The information
will be combined with field observations of population dynamics, production
and spatial distribution of zooplankton and fishes collected in this and
related projects to describe and understand invasion dynamics of Cercopagis and determine if these cercopagids have disrupted the Lake Michigan food
web.

IFYLE Cruise Data
This database includes physical, chemical, and biological data gathered by IFYLE cruises during 2005. Water chemistry, CTD profiles, fluorometry, zooplankton, fish trawls and towed instrument measurements are reported here. This data is shared by scientists participating in the IFYLE project, thus much of it is password-protected at the current time.

Abundance, Biomass, and Species Composition of Benthic Macroinvertebrate
Populations in Saginaw Bay, Lake Huron, 1987-1996
The abundance (number per grab sample) of all taxa collected between 1987
and 1996 with the Ponar grab. Variables include year, season, station,
replicate number, and taxa.

GRP Map Maker
A User's Guide to Spatial Models of Fish Habitat Combining Acoustic Data
and Bioenergetics Models. GRP Map Maker allows uses to convert data on
fish distribution and on simple environmental measures into measures of
fish growth rate potential, fish maximum potential consumption, and maximum
fish growth.

Program Background This research program focuses primarily on key components of the Great Lakes food web and the links between physical, chemical, and biological processes that impact important processes in ecosystem function. Although long-term trends in key components are examined, life history studies and process research are emphasized so that GLERL's expertise can be applied to problems in a variety of ecosystems that are geographically and biologically diverse. Goals: Improve our knowledge and understanding of food web processes and dynamics, and their relationship to environmental quality and living resources in Great Lakes and coastal marine ecosystems. Apply this knowledge better understand the causes, effects, and solutions to problems such as eutrophication, toxic contaminants, nonindigenous species invasions, habitat modification, and climatic variations Recent Publications HOOK, T.O., M.J.
