BENTHIC MACROINVERTEBRATE AND PERIPHYTON MONITORING IN THE SUWANNEE RIVER BASIN IN FLORIDA 1: OVERVIEW AND BIOGEOGRAPHY
periphytic algae
Periphytic Algae
  • Micro- to macroscopic algae growing on hard surfaces
  • Major source of autochthonous (“in-stream”) primary production
  • Respond to natural and human-created changes in water quality
  • Integrate environmental effects over time
benthic macroinvertebrates
Benthic Macroinvertebrates
  • Invertebrates retained by 0.5 mm mesh sieve
  • Ecologically important group of animals in all aquatic ecosystems in the drainage
  • Also respond to natural and human-created changes in water quality and habitat
  • Integrate environmental effects over time
suwannee river drainage benthic community sampling in florida
Suwannee River DrainageBenthic Community Sampling in Florida
  • Fla. Fish & Wildl. Conservation Commission(resource assessments)
  • Fla. Dept. of Environmental Protection(monitoring, impact assessment, stream bioassessment program)
  • Suwannee River WMD(SWIM monitoring, basin assessments)
  • USGS Biol. Resources Division(sturgeon & seatrout food resources)
  • USEPA(NPDES impact studies)
  • Private consultants(point source impact studies, NPDES monitoring)
  • Citizen groups
suwannee river water management district benthic monitoring program
Suwannee River Water Management District Benthic Monitoring Program
  • began in 1989; currently continuing
  • quarterly sampling
  • multiple gear types:
    • Hester-Dendy, Periph. & dip net (streams)
    • Petite ponar (streams and lakes)
  • mainly streams (some lake studies)
  • same organization doing sampling
  • same taxonomists
