Presentation Transcript

  1. BENTHIC MACROINVERTEBRATE AND PERIPHYTON MONITORING IN THE SUWANNEE RIVER BASIN IN FLORIDA 3: SPATIAL AND TEMPORAL TRENDS

  2. Objectives • Spatial Trends Temporal Trends Benthic Macroinvertebrates Periphyton Water Quality

  3. Best Available Data 1989 - 2003 Hester-Dendy sampler Periphytometer

  4. Application • Expand knowledge on ecological forcing factors (e.g., eutrophication) Provide supporting information for habitat control points for MFLs Define temporal baselines for MFLs

  5. Spatial Trends • Principal Component Analysis to display multi-dimensional data in 2 dimensions

  6. PCA Results • Principal Component Analysis

  7. PCA Results Factor 1 + Ablabesmyia ramphe (.35) + Tribelos fusicorne (.31) + Slavina appendiculata (.25)Factor 2 - Stenonema exiguum (.32) + Hydropsyche rossi (.31) + Corydalus cornutus (.28)

  8. Upper Santa Fe Lower Santa Fe With Factor 1 Upper Suwannee Lower Suwannee Factor 2

  9. Seasonal Kendall-Tau TrendsPowerful - remove seasonal effects - adjust p values for autocorrelationQuantitative - estimate rates of changeRobust - non-parametric - meta-analysis
