The Great Lakes - St. Lawrence Research Inventory is an interactive, Internet-based, searchable database created as a tool to collect and disseminate up-to-date information about research projects in the Great Lakes - St. Lawrence Region.
Projects

  • The Effects of Round Goby on Yellow Perch-Amphipod Interactions Within Zebra Mussel Colonies and Macrophyte Beds.

    Created by jeff.reutter on April 3, 2002
    March 1, 2002 to February 28, 2005CompletedProject

    1. To compare the spatial distributions of G. fasciatus and E. ischnus before and after round goby invasion. 2. To investigate the effect of round goby on the yellow perch-amphipod interaction and yellow perch growth in macrophyte and zebra mussel habitats. 3. To determine the role of cannibalism and intraguild predation in the interaction between the native and exotic amphipod. Keywords: Growth,Habitat,Macrophyte,Round goby,Zebra mussel.

  • Sonochemical desorption of mercury laden sediments.

    Created by jeff.reutter on April 3, 2002
    March 1, 2000 to February 28, 2003Project

    The purpose of this project is to investigate the application of sonolysis to sediment polluted with mercury. The specific objectives of this study are: To demonstrate the ability of sonication to remove inorganic and methylmercury from synthetic and natural sediments; 1. To show that sonochemical techniques transform methylmercury to inorganic mercury once it enters the soluble phase; 2. To characterize the role of sediment matrix parameters in sonochemical remediation; and 3. To identify key design variables in the sonochemical remediation of contaminated sediments.

  • Analysis of Constraints on Growth and Survival of Juvenile Atlantic Salmon in Lake Ontario Streams.

    Created by jack.manno on April 3, 2002
    October 19, 1999 to December 31, 2000Project

    To provide information on the major factors affecting survival and growth of larval Atlantic Salmon and to reestablish this species to its native range. Keywords: Atlantic salmon,Bioenergetic,Biomass,Development.

  • Influence of Upwelling Events on Larval and Juvenile Yellow Perch.

    Created by john.janssen on April 3, 2002
    March 1, 2000 to February 28, 2002Project

    1. To determine factors that affect the survival of yellow perch in Lake Michigan. 2. To determine where young of the year yellow perch reside and are transported during the period between when the yolk is absorbed and when they become demersal. 3. Document, based on thermal history recorded in the otoliths and stabe isotope signatures in the muscle, whether life histories of alewife (drift whith the offshore currents) or johnny darter (stay in nearshore water) are closer to yellow perch thermal histories. 4.

  • Heavy metal bioremediation using genetically altered biomass.

    Created by jeff.reutter on April 3, 2002
    March 1, 2000 to February 28, 2003Project

    To identify trace metal binding peptides that have high affinity for lead, cadmium, copper and mercury. To introduce genes encoding trace metal binding peptides into transgenic Chlamydomonas to increase its trace metal binding capacity. To develop production and delivery systems for the use of trace metal accumulating algae to remediate areas of concern in the Great Lakes region. Keywords: Cadmium,Copper,Lead.

  • Advancing tissue residue-based risk assessment: field and laboratory tests of the critical body residue hypothesis.

    Created by jeff.reutter on April 4, 2002
    March 1, 2000 to February 28, 2002Project

    The concept of the critical body residue (CBR) seeks to provide an alternative for interpreting risk. Instead of referencing risk to environmental concentrations of contaminants, biological effects of contaminant needed to cause a specified effect. Denoted a critical body residue (CBR), the CBR hpothesis argues that the internal body residue in an organism at the site of action needed to cause contaminants with identical modes of action.

  • Development of Water Markets for Northeastern Illinois.

    Created by martin.jaffe on April 4, 2002
    March 1, 2000 to February 28, 2002Project

    To collect baseline water usage data and assess the institutional and legal mechanisms needed for market-based strategies to manage the regions' water supplies. Keywords: Policy, Urban.

  • Workshop on Applications of Remote Sensing Technology in the Lake Ontario and St. Lawrence River Drainage Basin .

    Created by jack.manno2 on April 4, 2002
    January 1, 2000 to December 31, 2000Project

    To explore strategies of integrating these technologies to address systems-wide and site-specific environmental problems identified by the scientific community as significant in the region, and to support the preparation of an integrated and multi-campus proposal to implement the results of this planning workshop.

  • Genetic Characterization of Walleye Stocks Based on Mitochondrial and Nuclear DNA Sequences.

    Created by jeff.reutter on April 4, 2002
    March 1, 1998 to February 28, 2001Project

    To characterize genetic stock structure and spatial patterning of walleye Stizostedion vitreum populations in spawning regions, lake basins, and among the Great Lakes, in order to evaluate diversity and delineate essential areas for its maintenance by fisheries management.

  • Benthic-Pelagic Coupling: Community Responses to Round Goby Predation on Zebra Mussels.

    Created by jeff.reutter on April 4, 2002
    March 1, 1998 to February 28, 2001Project

    To test the hypothesis that invading round gobies, by consuming sufficient zebra mussels, can alter the benthic and pelagic communities in the Great Lakes. We propose to quantify 1) the consumptive effects of round gobies on zebra mussels, 2) determine the explicit responses of benthic organisms (macroinvertebrates and periphython) to reduction of zebra mussels, 3) characterize the effect of reduced zebra mussel filtration on phytoplankton and zooplankton, and 4) quantify reallocation of nutrients (N,P) between benthic and pelagic regions of the ecosystem.
