This book was released on 2000 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussel feeding was restricted by reduced delivery of algae into the less-turbulent "concentration boundary layer" and by competition within the mussel colony for algae. I measured the relative magnitude of algal consumption by zooplankton in situ and by mussels in the lab relative to lake algal abundance and photosynthesis. Although seasonal phytoplankton successional patterns typical of north temperate lakes without zebra mussels have persisted after mussels became established in western Lake Erie, total phytoplankton biomasses were lower and Cyanobacteria rarer. However, changes in nutrient concentrations can account for shifts in algal species composition. Based on a comparison of primary productivity and algal standing crop phytoplankton were capable of reproducting once or twice a day. Grazing by free swimming, large-bodied crustacean zooplankton was sufficient to explain seasonal changes in algal abundance without considering zebra mussel impact at all. Even when seasonally abundant (maximum of 750 L-1 during August 1993), zebra mussel veligers grazed pelagic algae at an insignificant rate (generally 1- 3% with a maximum of 7.1%) relative to other zooplankton. Thus, potentially only the benthic adult zebra mussel stage with its larger biomass could be significantly impacting phytoplankton. Grazing by sedentary adult zebra mussels present in high densities was insufficient to overwhelm phytoplankton production.

Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussels, one of the most recent non-indigenous species to invade the Great Lakes, achieves extraordinary population densities in the lower lakes. They draw in water and filter a broad range of suspended particles, and have the potential to alter contaminant cycling in invaded lakes. They are also a conduit for contaminants and energy to higher trophic levels by serving as prey for fish and waterfowl. This study assesses the suitability of the zebra mussel as an organic contaminant biomonitor in the lower Great Lakes and also addresses its importance to waterfowl diets and body burdens or organocontaminants. It presents results of elimination rate determinations for polychlorinated biphenyl (PCB) congeners and contaminant levels in mussels from vaiours sites in Lake Erie and Lake St. Clair; results of experiments to determine the contribution of food to zebra mussel PCB accumulation; and statistical analyses of contaminant data for six species of ducks, examining differences in contaminant levels between those that consumed zebra mussels and those that did not.

Book Synopsis The Effects of Zebra Mussels on the Lower Planktonic Foodweb of Lake Champlain by : Emily K. Brines
Download or read book The Effects of Zebra Mussels on the Lower Planktonic Foodweb of Lake Champlain written by Emily K. Brines and published by . This book was released on 2004 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussels rapidly decreased total phytoplankton abundance, including the cyanobacteria. In this experiment, however, these algae were not very abundant nor were there large colonial forms present. Zebra mussels also caused significant declines in protozoans, rotifers and nauplii. Soluble reactive phosphorus and total nitrogen increased over time in zebra mussel treatments and the changes in these nutrients resulted in a decrease in N:P ratios in those treatments. No impacts of macro zooplankton were observed, however, macrozooplankton abundances in these treatments were far lower than planned. Zebra mussels clearly are capable of strongly impacting the lower planktonic foodweb; it is also possible that these effects will be felt by higher trophic levels of the planktonic foodweb.
