Spatial and temporal influences of environmental conditions on benthic macroinvertebrates in northeast Lake Jesup, central Florida.

Popis výsledku v původním jazyce

The benthic macroinvertebrate community composition and selected water and sediments physico-chemical parameters at 15 permanent sampling stations in northeast Lake Jesup, central Florida, were studied monthly from December 1996 to December 1997. Crustacea (primarily Ostracoda) were numerically dominant (mean 3,645/m2), followed by Oligochaeta (898/m2), Gastropoda (mostly Tryonia aequicostata 898/m2), Chironomidae larvae (predominantly Glyptotendipes paripes 383/m2), Chaoboridae larvae (112/m2) and Hirudinea (107/m2). Ordination analysis (CCA and variation partitioning) showed that month of sampling and sampling station together explained 64% of benthic community variability; sampling station explained 45% and sampling month 19% of variation. Significant density differences of various taxa were noted between sampling stations, but not between months of sampling. Clustering of benthic community by using TWINSPAN revealed differences between sand and soft organic sediments. CCA indicated
