General Sites on Freshwater Invertebrates.

• George Mason University students have created a mighty fine website for benthic macroinvertebrates at http://osf1.gmu.edu/~avia/intro.htm. It is illustrated, broken out by levels of water quality, and has a handy glossary. {note: all images are copyrighted by Jones & Bartlett Publishers, so take care on with your uses of this site}
• Northeast Ohio Rivers Project (NORP) (http://rock.geo.csuohio.edu/norp/norp.htm) Cleveland State University (affiliate of the Global Rivers Environmental Education Network) has posted a nice set of pages with fairly good pictures of Ohio macroinvertebrates with basic taxonomic information on:
  • "Pollution Sensitive Organisms" (http://rock.geo.csuohio.edu/norp/bmi1.htm)
  • "Pollution Intermediate Organisms" (http://rock.geo.csuohio.edu/norp/bmi2.htm)
  • "Pollution Tolerant Organisms" (http://rock.geo.csuohio.edu/norp/bmi3.htm)
  • "Other Organisms" (http://rock.geo.csuohio.edu/norp/bmi4.htm)
