Zooplankton Abundance And Diversity In A Hydrilla Infested Central Florida Lake, Don C. Schmitz
Zooplankton Abundance And Diversity In A Hydrilla Infested Central Florida Lake, Don C. Schmitz
Retrospective Theses and Dissertations
Zooplankton abundance, hydrilla biomass, and physicochemical parameters were sampled for one year in a small central Florida lake. Annually, rotifers comprised most of the species collected and were the most abundant zooplankton group. Hydrilla biomass was lowest during winter and spring while orthophosphate and phtoplankton concentrations were highest. Zooplankton densities were highest when hydrilla biomass was low. Small-bodied limnetic herbivores comprised most of the zooplankton during the spring. Zooplanton abundances were lowest during summer and fall and may have been either directly or indirectly related to the hydrilla growth. Factors, such as lower phytoplankton and dissolved oxygen concentrations, possible increased …
