This book was released on 2007 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream flow is a major vector for zebra mussel spread among inland lakes. I hypothesized that vegetated waterways, i.e. wetland streams, would hinder downstream dispersal of zebra mussels in connected inland lake systems. To test this hypothesis, veliger (larva) abundance, recruitment, and adult mussels were surveyed in four lake-wetland systems in southeastern Michigan, USA from May through August 2006. Sampling was conducted downstream of the zebra mussel invaded lakes, beginning at the upstream edge of aquatic vegetation and continuing downstream through the wetland streams. Results showed that veliger abundance decreased rapidly in vegetated waterways compared to their previously reported rates of decrease in non-vegetated streams. Veligers were rarely found more than 1 km downstream from where vegetation began. Newly recruited individuals and adults were extremely rare beyond open water in the study systems. These results suggest that densely vegetated aquatic ecosystems limit the dispersal of zebra mussels downstream from invaded sources. Natural, remediated and constructed wetlands may therefore serve as a protective barrier to help prevent the spread of zebra mussels and other aquatic invasive species to other lakes and ecosystems.

This book was released on 2016 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussels have recently invaded Central Texas and more information is needed to predict their spread in this region and inform management decisions. Therefore, I examined riverine zebra mussel dispersal, settlement, and growth downstream of Lake Belton, TX, invaded by zebra mussels in 2013. Veliger samples and settlement of juveniles on artificial substrata was monitored at a site in the lake and six sites in the Leon and Little Rivers, 0.4 to 54.7 river kilometers (rkm) downstream of the lake outlet. Veliger density declined with distance downstream with the greatest densities recorded at sites closest to the lake outlet (0.4 and 2.5 rkm). Veligers were found up to 13 rkm downstream. This decline was represented best with a logarithmic decline in May, Aug, Oct 2015 (R2 = 0.75 to 0.94), and with an inverse power relationship in June and September 2015 (R2 = 0.53 to 0.73). No clear pattern was found in April 2016 (R2=0.32, p = 0.06). In contrast, maximum juvenile settlement (437 +/- 75 m-2) occurred 2.5 rkm downstream in August 2016, but not immediately downstream of the lake. Differences in settlement rates between sites could not be explained by differences in physico-chemical parameters such as temperature or turbidity as they did not differ significantly between sites. No mussels were found at 27 and 55 rkm downstream on artificial or natural substrata between May through December of 2015, but juvenile mussels were found there in April 2016. This suggests that zebra mussels were dispersal limited in 2015, and were able to disperse further downstream in 2016 probably facilitated by high discharge from Lake Belton.

Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of the zebra mussel in North American waters has caused great concern among industrial and recreational users of these waters. This bivalve mollusk is a biofouler that attaches to any firm substrate (e.g. rocks, piers, water intake pipes, boat hulls) and has already created significant problems for raw water users such as water treatment plants and power plants. Zebra Mussels: Biology, Impacts and Control provides essential information regarding the biology of the zebra mussel in North America and Europe, presents case studies of environmental and industrial impacts, and outlines control strategies. Summary articles detail its life history, origins, and morphology. The book also examines techniques used to culture and maintain this organism in the laboratory. Thirty-two color plates illustrate some of the dramatic problems created by the explosive population growth of this species. Zebra Mussels: Biology, Impacts, and Control is an important resource for ecologists, conservationists, environmental consultants, water quality engineers, regulatory officials, power utilities, and libraries.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies that differentiate between lake type or origin, i.e., natural lakes and reservoirs, or that focus solely on reservoirs are rare, especially at broad scales. These facts lead to reservoirs being less well understood compared to natural lakes. It is known that adding dams/impoundments alters the flow regime of the original water body and changes surface water connectivity. However, the impact of these alterations on invasive species dispersal is widely unknown. Reservoirs are also thought to have higher levels of human disturbance, which can provide opportunities for non-native species such as the zebra mussel (Dreissena polymorpha) to invade and establish. Surface water connections allow zebra mussel larvae to flow from one waterbody to another. Additionally, trailering of recreational boats among lakes can promote overland dispersal of zebra mussels through live wells and boating equipment. Although such connectivity promotes zebra mussel spread, we do not yet know how zebra mussels vary according to lake type nor the relative roles of surface and human connectivity and lake type. Taking a data-intensive approach at the macroscale, we ask: Are zebra mussels more common in reservoirs than in natural lakes? How does surface water and human connectivity influence the presence of zebra mussels in reservoirs and natural lakes? To answer these questions, we used 907 lakes within a 17-U.S. state extent and data from a variety of sources. Water quality, surface water connectivity, and human disturbance data were from the LAke multi-scaled GeOSpatial and temporal (LAGOS) database, public lake access sites were from the United States Geological Survey (USGS), and zebra mussel presence data were from the USGS Nonindigenous Aquatic Species database. We characterized surface water connectivity using six unique lake connectivity classes. We characterized human connectivity two ways: watershed road densities measured in meters per hectare and, for a 3-state subset of the study extent, the presence of public access sites on lakes. We characterized surface water connectivity using a lake connectivity classification based on lake and stream inflow(s)/outflow(s). Using logistic multiple regressions and controlling for region and lake chlorophyll a concentrations, we found that a higher proportion of reservoirs have zebra mussels compared to natural lakes for the 17-state extent. At this same spatial extent, we found that more highly connected lakes, both by humans and surface waters, were more likely to have zebra mussels present, regardless of lake type. Finally, at the 3-state extent, lakes with a public access site were more likely to have zebra mussels than those without, regardless of lake type. We conclude that not all 'lakes' are equally likely to have zebra mussels present and that both surface water and human connectivity are important predictors of zebra mussel presence. This study improves the understanding of how natural lakes and reservoirs differ and the extent to which reservoirs disproportionately harbor the invasive zebra mussel, which can improve management and prevention. For example, these results suggest that legislation and management focused on uninvaded reservoirs that are highly connected may help slow the spread of this invasive species.
