“…Furthermore, temperature and food in the epilimnion are useful for the zooplankton in this region, but the highest fish predation is seen at this layer, as well. Trade-offs exist between feeding and predator avoidance (Burns and Mitchell, 1980;Masson et al, 2001;Andersen et al, 2004;Ignoffo et al, 2005). The composition and dynamics of the zooplankton community are affected by interspecies competition and selective predation pressures.…”

“…The composition and dynamics of the zooplankton community are affected by interspecies competition and selective predation pressures. Top-down pressure by planktivorous fish can reduce the population of large cladocerans (Masson et al, 2001;Morozov et al, 2007;Eggermont and Martens, 2011).…”

“…In freshwater ecosystems, the community structure of zooplankton is especially affected by climatic, physical, and chemical characteristics; geographical factors; and inter-and intraspecific competition (Gulati and DeMott, 1997;Masson et al, 2001;Hobaek et al, 2002;Persson et al, 2007). Zooplankton species are commonly utilized as bioindicators for environmental changes since they respond quickly to environmental pollution as a whole community (Whitman et al, 2004;Altindag et al, 2009;Kaya et al, 2010;Sellami et al, 2010).…”

“…The mechanism is an increase in the potential encounter sphere of each individual fish. Planktivorous fish tend to maximize foraging by moving to areas that provide sufficient light for visual feeding (Masson et al 2001;Gjelland et al 2009). Fish can position themselves vertically in the water column based on light intensity and may remain at levels that exceed the 10 23 lux levels required for foraging (Bohl 1980).…”

“…Although these modeling efforts suggest that many transparent systems provide sufficient light for fish to forage at depths that exceed the migration depth of zooplankton, fish often do not exploit these environments. For example, in a deep, transparent lake in France, planktivorous YOY perch were concentrated in the epilimnion or nearshore regions, while the zooplankton (cladocerans and cyclopoids) were found at depths of 10-20 m or more during the day (Masson et al 2001). Similarly, in Crater Lake, the light level required for kokanee foraging was adequate to a depth of 150 m. However, kokanee were concentrated at a mean daytime depth of 50-74 m, while cladocerans were most dense between 80 and 120 m ).…”

The current prevailing theory of diel vertical migration (DVM) of zooplankton is focused largely on two biotic drivers: food and predation. Yet recent evidence suggests that abiotic drivers such as damaging ultraviolet (UV) radiation and temperature are also important. Here we integrate current knowledge on the effects of abiotic factors on DVM with the current biologically based paradigm to develop a more comprehensive framework for understanding DVM in zooplankton. We focus on ''normal'' (down during the day, up at night) DVM of holoplanktonic, primarily herbivorous zooplankton. This new transparency-regulator hypothesis differentiates between structural drivers, such as temperature and food, that vary little over a 24-h period and dynamic drivers, such as damaging UV radiation and visual predation, that show strong variation over a 24-h period. This hypothesis emphasizes the central role of water transparency in regulating these major drivers of DVM. In less transparent systems, temperature and food are often optimal in the surface waters, visual predators are abundant, and UV radiation levels are low. In contrast, in more transparent systems, vertical thermal gradients tend to be more gradual, food quality and quantity are higher in deeper waters, and visual predator abundance is often lower and damaging UV radiation higher in the surface waters. This transparency-regulator hypothesis provides a more versatile theoretical framework to explain variation in DVM across waters of differing transparency. This hypothesis also enables clearer predictions of how the wide range of ongoing transparency-altering local, regional, and global environmental changes can be expected to influence DVM patterns in both inland and oceanic waters of the world.Diel vertical migrations (DVM) of zooplankton in the world's lakes and oceans comprise some of the most widespread and massive migrations of animals on Earth. These striking migrations across strong vertical habitat gradients have inspired numerous ecological and evolutionary studies addressing mechanisms of habitat selection and consequences for species interactions. These migrations also have important implications for water quality and fisheries production as well as biogeochemical cycling. Natural and anthropogenic environmental changes, such as shifting local land use patterns and regional to global climate change, are altering water transparency and have the potential to affect DVM in lakes and oceans worldwide. The purpose of this article is to provide a common theoretical framework for understanding variation in the drivers of DVM across transparency gradients with a particular emphasis on recent advances in our understanding of the role of ultraviolet radiation (UV).Many environmental factors are recognized as providing both important proximate cues as well as ultimate consequences of adaptive significance for DVM, including light, temperature, food availability, and predation pressures (Table 1; Lampert 1989;Ringelberg 1993;Hays 2003).

Although parasites are expected to affect their host's fitness, quantitative proof for impacts of parasitism on wild populations is hampered by confounding environmental factors, including dietary resource. Herein, we evaluate whether the physiological conditions of European perch (Perca fluviatilis) in three large peri‐alpine lakes (Geneva, Annecy, and Bourget) depend on (a) the nutritional status of the juvenile fish, as revealed by stable isotope and fatty acid compositions, (b) the prevalence of the tapeworm Triaenophorus nodulosus, a parasite transmitted to perch through copepod preys, or (c) interactive effects of both factors. At the scale of lake populations, the deficit in growth and fat storage of juvenile perch during their first summer coincides with a high parasite prevalence and also a low quality of dietary resource. Yet, at the individual level, parasites had no evident effect on the growth of the juvenile perch, while impacts on fat storage appeared only at the highest prevalence of the most infected lake. Fatty acid and stable isotope analyses of fish tissue do not reveal any impact of T. nodulosus on diet, physiology, and feeding behaviour of fish within lakes. Overall, we found a low impact of parasitism on the physiological condition and trophic status of juvenile perch at the end of their first summer. We find instead that juvenile perch growth and fat storage, both factors tied to their winter survival, are under strong nutritional constraints. However, the coinciding nutritional constraints and parasite prevalence of perch juveniles in these three lakes may result from the indirect effect of lake nutrient concentrations, which, as a major control of zooplankton communities, simultaneously regulate both the dietary quality of fish prey and the host–parasite encounter rates.
