Dreissenid mussels as ecosystem engineers 

Goal: Describe Dreissena effects on ecosystem function

  • Dreissena donate resources to bottom algae
  • Dreissena affect native mayfly habitat selection

The Maumee River-Bay ecosystem: critical fish habitat
Goal: Quantify river habitat use by walleye and other fish to assess Maumee contribution to lake-wide fishery.

  • Greater diversity of larval fish compared with 1970s suggests partial recovery; consistent with improved water quality
  • About 500,000 adult walleye enter the river to spawn
  • About 50 million larval walleye produced each year (2010-13)
  • Migrating fish may affect river foodweb

Nearshore community: shoreline habitat matters!
Goal: Quantify effect of shoreline alterations on number of fish species

  • Partnership with Ohio DNR-DOW
  • Statistically sound sampling protocol for nearshore fish community for DOW
  • Effect of armor depends on background habitat
  • Number of fish species always higher with shoreline vegetation
  • Greater benthic invertebrate diversity with shoreline vegetation

Hydroacoustic determination of walleye distribution in Lake Erie

Goal: Compliment long-term gill-net sampling with hydroacoustics to improve population estimate

  • Partnership with Ohio DNR-DOW

Land – Water – Fish Connections
Goal: Link changes in the watershed & climate to fish growth

  • Lab: Young yellow perch feed at low levels with algal turbidity
  • IBM: Extended algal blooms lower growth of young fish
  • SWAT & Simulations: Expected temperature increases can extend algal blooms and lower fish growth
  • SWAT & Simulations: Current land-use promotes algal blooms & smaller yellow perch
