Influence of upwelling events on larval and juvenile yellow perch project

Principal Investigator: John Janssen
Affiliation: University of Wisconsin-Milwaukee WATER Institute
Initiation Date: 2000
  • Determine the factors that affect the survival of larval yellow perch in Lake Michigan
  • Determine where young of the year yellow perch reside and are transported during the period between when the yolk is absorbed and when they are dispersed
  • Document, based on thermal history in the otoliths and stable isotopes in the muscle whether life histories of alewife or benthic fish are closer to yellow perch thermal life histories
  • Determine the impact of wind-driven movements of water masses on young of the year yellow perch distribution

Predicting Zebra Mussel Transport in Rivers and Estuaries

Principal Investigator: Chris Rehmann
Affiliation: University of Illinois Urbana-Champaign
Initiation Date: 1999
  • Identify the main mechanisms affecting physical transport in the Illinois and Hudson Rivers
  • Model the less well-understood mechanisms in detail 
  • Construct a single model that combines the physical transport mechanisms with the biology and population dynamics
  • Identify the processes controlling the transport and settlement patterns

Outdoor Recreation and the NSRE: An Examination of Nature Based Learning Activities with a Focus on Water

Principal Investigator: Joseph O'Leary
Affiliation: Purdue University
Initiation Date: 1998
  • Provide and enhance the description of recreation participants in the nature based and specfiically
    water related learning activities
  • Segment recreation participants by applying the Three-step Procedural Model (activity packages,
    sociodemographic background, trip-related characteristics, environmental attitudes; and expenditure information)
  • Determine how the activity segments differ in terms of geographic, sociodemographic, travel trip, expenditure, attitudes and other characteristics
  • Provide recommendations for public and private recreation organizations interested in the outdoor
    recreation market
