“…In general, these impacts were very subtle, and not connected directly with the level change, but rather indirectly. Direct effects on invertebrates (Aroviita & Hämäläinen, Baumgärtner et al, Muskó et al, Werner & Rothhaupt, this volume) and zooplankton (Mageed & Heikal, 2006) include changes in the structure and dynamics of taxa that cannot withstand dry periods which subsequently lead to a limiting of their distribution by low water levels (Rossa & Bonecker, 2003;Bowers & De Szalay, 2004. Indirect effects are generally through alteration of habitats (e.g.…”

Effects of water-level fluctuations on lakes: an annotated bibliography

Water-level fluctuations (WLF) in lakes and rivers, especially their extent, frequency and duration, are dominant forces controlling the functioning of these ecosystems. In particular, WLF play an important role in the lake's littoral and aquatic-terrestrial interface processes. WLF may take place on different spatial and temporal scales under natural conditions but water levels have been artificially modified in regulated lakes, and their impacts are expected to be enhanced within the actual global change scenarios with forthcoming management problems. This article presents an overview on the literature published on this important topic since 1991 by using journals indexed in the ISI Web of Knowledge. The overall objective was to examine temporal and spatial trends in publications on WLF, the specific aspect of WLF concerned and their main effects. Throughout the article we have used case studies to illustrate different effects of WLF on the variety of lake habitats and indicators that have been studied. Overall, the number of papers published on the subject since the 1990s has risen steadily, when less than ten papers were published each year; until 2006 and peaking in 2005. The greatest number of papers on WLF has been carried out in Europe and North America (c. 73%). These data also showed that the effects of WLF have not been studied equally for different groups of organisms. There is a greater interest on macrophytes, which are the most studied group of organisms (18.4% of the papers). Nearly 7% of the papers deal with algae, and zooplankton and invertebrates account for a 7% followed by fish. WLF effects on ecosystems are very complex, and the biological effects in lakes are greatest in shallow water and littoral areas, where even small changes in water levels can result in the conversion of large areas of a standing-water environment in air exposed habitats. Finally, these data might serve to highlight knowledge gaps still existing on this topic and, in particular, some of the approaches that can potentially contribute to solve several of these lacunae are explored.

“…However, several "refuge" sites for unionids have been found in nearshore wetland habitats of Lake Erie where zebra mussels are present, but at low densities. A viable community of 21 species was found in Metzger Marsh along the south shore of Lake Erie in 1996 (Nichols and Wilcox, 1997), and a community of 15 species was found in nearby Crane Creek Marsh in 2001 (Bowers and de Szalay 2004). Thompson Bay, the outer harbor of Presque Isle Bay, supports a smaller community of only nine species, and annual monitoring between 1992 and 2006 suggests that the community is stable (E.C.…”

“…Average rates (# zebra mussels/unionid) were b1 in Metzger Marsh (Nichols and Amberg 1999), zero in Thompson Bay (Schloesser and Masteller 1999) and 4 in Crane Creek Marsh (Bowers and de Szalay 2004), whereas average infestation rates in the delta ranged from 3 to 47 (Zanatta et al 2002). In Metzger Marsh, the limited infestation rates are likely due to the presence of soft sediments, which allow unionids to burrow, thereby smothering any attached zebra mussels (Nichols and Wilcox 1997).…”

“…the species' persistence after the Zebra Mussel invasion can be attributed to its opportunistic life history strategy (high fecundity, early age of reproduction, and short life-span; Haag 2012) and its association with habitats, i.e., soft substrates, that are not well suited for Zebra Mussel and allow for native mussels to burrow (Bowers and Szalay 2003;Zanatta et al 2015). Low density populations of mussels at risk have also been detected in north shore Lake ontario coastal wetlands (Reid et al 2014).…”

“…over the past 15 years, an increasing number of studies have demonstrated the importance of Great Lakes coastal wetlands to freshwater mussel conservation. compared with adjacent open water habitat, wetlands are less suitable for dreissenid colonization and survival (Bowers and Szalay 2003;Sherman et al 2013) and, thus, provide a refuge for native mussels. Remnant mussel assemblages have been identified in coastal areas of lakes Erie, Huron, ontario, and St. clair (Zanatta et al 2002;Bowers and Szalay 2003;Sherman et al 2013;Reid et al 2014;Zanatta et al 2015).…”

. 2016. Remnant freshwater mussel diversity in Rondeau Bay, Lake Erie. canadian Field-naturalist 130(1): 76-81.in 2014 and 2015, 27 sites in Rondeau Bay, ontario, canada, were surveyed for freshwater mussels. Rondeau Bay is a large coastal wetland on the north shore of Lake Erie. twenty-three species were identified from 120 live mussels, 15 fresh whole shells, 329 weathered whole shells, and 1121 weathered valves. Live individuals of the following species were collected: Eastern pondmussel (Ligumia nasuta; endangered in canada), Giant Floater (Pyganodon grandis), Round pigtoe (Pleurobema sintoxia; endangered in canada), and three-ridge (Amblema plicata). Fresh whole shells of the Mapleleaf (Quadrula quadrula; threatened in canada) were also found. Most species (78%), including 7 species at risk, were collected only as weathered shells. these results indicate a substantial decline in freshwater mussel diversity since the Zebra Mussel (Dreissena polymorpha) invasion of Lake Erie. Evidence shows that a viable population of only Giant Floater remains.
