“…Pelagic invertebrate predators may substantially regulate zooplankton communities (DOD- SON, 1972;LANE, 1979;BRABRAND et al, 1986). Invertebrate predators are also important food items for many fish species and their density often fluctuates reciprocally with the density of planktivorous fish (POPE et al, 1973;BENNDORF et al, 1988).…”

“…In a survey of 696 glaciated lakes in eastern North America it was among the 10 most common species (N species 5 48), occurring in 45% of lakes (Carter et al 1980). Leptodora is a voracious predator of small-to medium-sized zooplankton (Andrews 1948;Herzig and Auer 1990) and is thought to have strong effects on the abundance (Hall 1964;Herzig 1995;Uusitalo et al 2003), seasonality (Costa and Cummins 1969;Herzig 1995), and composition of zooplankton communities (Lane 1979;Yan et al 2002;McNaught et al 2004). Although Leptodora densities are influenced by macro-invertebrate predators such as Bythotrephes in boreal lakes (Weisz and Yan 2011), this taxon remains an important predator in productive European and North American lakes (Enz et al 2001;Palmer et al 2001) where Bythotrephes abundance has declined because of eutrophication (Therriault et al 2002).…”

In an intensive study of the vertical and horizontal distribution of zooplankton in a eutrophic lake (Katepwa Lake), we found that only adult Leptodora kindtii (. 5 mm in body size) exhibited diel vertical migration (DVM), whereas juvenile Leptodora (, 5 mm) and other zooplankton species did not. Even though a longitudinal survey of five lakes (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004) indicated that variation in Leptodora density was correlated with several indicators of habitat use (e.g., water temperature) and resource availability (e.g., zooplankton abundance), feeding experiments performed in both lit and unlit conditions demonstrated that a vertebrate predator (perch) strongly reduced Leptodora abundances under all conditions and always preferentially selected large-bodied individuals. Collectively, this evidence suggests that the migratory behavior of large Leptodora is consistent with an antipredator defense strategy. To estimate the ecological significance of Leptodora DVM behavior, we modeled how predation rates on different zooplankton taxa differed between day and night in Katepwa Lake. We found that Leptodora had as much as five-fold higher prey-specific predation rates at night, particularly for intermediatesized prey. We conclude that ignoring the habitat use, size-structure, and vertical migration behavior of Leptodora could considerably underestimate the significance of invertebrate predation in lake food webs, particularly in eutrophic lakes where Leptodora can coexist at high densities with planktivorous fish.

“…The role of vertebrate predators in determining zooplankton communities in lakes and in altering the structure from dominance by large-sized species to dominance by small-sized ones has been well reported (Kerfoot, 1980;Lazzaro, 1987;Gliwicz and Pijanowska, 1989). Some studies suggest that invertebrate predators may substantially regulate zooplankton communities (Dodson, 1972;Lane, 1979;Brabrand et al, 1986). Leptodora kindtii used in the study as an invertebrate predator is a common pelagic cladoceran which prefers to feed on other species of Cladocera, especially Daphnia (Karabin, 1974;Hovenkamp, 1990;Lunte and Luecke, 1990;Wojtal et al, 1999Wojtal et al, , 2008.…”

-Daphnia longispina (O. F. Mu¨ller 1785) and Daphnia cucullata (G. O. Sars 1862), despite coexisting in similar densities in the lake, showed different demographic cycles. To search the causes of such variances between the two Daphnia, selected population parameters (density, body proportions, reproductive output) were correlated with the density of five dominant and potentially competitive species of Cladocera. The same parameters were estimated in relation to predation pressure of vertebrates (planktivorous fish) and invertebrates (Leptodora kindtii (Focke 1844)). The obtained results show that competition had no apparent impact on life-histories of Daphnia. Different strategies of the two Daphnia resulted from the uneven effect of invertebrate and vertebrate predators. D. longispina that was affected by planktivorous fish and Leptodora kindtii invested in reproduction and carried big egg-clutches. D. cucullata, which was insignificantly influenced by fish, displayed low reproductive output but changed their body proportions in the process of cyclomorphosis when occurring with L. kindtii. Other life-history trade-offs altered during the year, in accordance with the intensity of predation pressure.
