“…The invasion of exotic planktivorous fish had a negative effect on water quality. In previous studies, lakes stocked with amounts of copepods, and low nutrient are usually associated with planktivorous fish (e.g., Benndorf et al, 2000;Mehner et al, 2008). Other study had also provided evidence supporting the above conclusion that the increase of copepod biomass or size structure, caused by the predation of planktivorous fish, had a negative effect on phytoplankton control and water quality (Blumenshine and Hambright, 2003).…”

-We investigated crustacean zooplankton communities and their relationships to environmental factors in 13 lakes of Yunnan-Guizhou plateau to determine whether there is a consistent relationship between trophic indicators and crustacean zooplankton biomass or size structure. The lakes showed a wide range of trophic status, with total phosphorus (TP) ranging from 0.013 to 0.268 mg.L x1 , and chlorophyll a from 0.9 to 76.26 mg.L x1. Continuous stocking with exotic planktivorous fish had taken place on a wide scale in these plateau lakes. About 36 species of Crustacea were found, of which Cladocera were represented by 20 taxa (12 genera), and Copepoda by 16 taxa (13 genera). Canonical correspondence analysis partitioned these species into two clusters. Physicochemical features and food-webs of different lakes seemed to be the key factors determining zooplankton species composition and distribution patterns. Between the 13 lakes, there was no significant relationship between cladocerans and chlorophyll a suggesting phytoplankton biomass was little controlled by macrozooplankton. The positive correlation between chlorophyll a and copepods suggested the high copepods biomass or size structure caused by the invasion of exotic planktivorous fish had a negative effect on water quality.

“…The models also predict that in systems where invertebrate predation is substantial, planktivory by fish may have a negative correlation with phytoplankton biomass. This phenomenon was observed in Lake Washington (Edmundson & Abella, 1988) and in biomanipulation experiments in Germany (Wissel & Benndorf, 1998;Wissel et al, 2000;Benndorf et al, 2000).…”

“…Classical cascade models are only applicable in those systems where the food web can be well approximated by a simple food chain. Besides phytoplankton, herbivorous zooplankton, and fish, lake food webs often contain invertebrate predators such as insect larvae and predatory crustaceans that both compete for food with, and are prey for, planktivorous fish (Dodson, 1974;Hall et al, 1976;Kerfoot & DeMott, 1984;Elser et al, 1987;Riessen et al, 1988;Edmondson & Abella, 1988;Soranno et al, 1993;Wissel & Benndorf, 1998;Wissel et al, 2000;Benndorf et al, 2000). Food webs where invertebrate predators are important cannot be modeled as a simple chain; food chain models may therefore give incorrect predictions in this situation.…”

“…The ingestible size spectrum is dependent on mouth gape size, which increases from smaller species like Chaoborus punctipennis and C. flavicans to C. trivittatus and C. americanus (Saether 1970). They are tactile ambush predators and can drastically alter zooplankton composition and abundance by intense predation pressure (Dodson 1972;Kajak and Rybak 1979;Yan et al 1991;Benndorf et al 2000;Ramcharan et al 2001). Recent studies estimate that more than 90% of northern temperate lakes are inhabited by Chaoborus (Wissel 2001).…”

Damaging UV radiation and invertebrate predation: conflicting selective pressures for zooplankton vertical distribution in the water column of low DOC lakes

et al. 2004

In nature most organisms have to manage conflicting demands of food gathering, predator avoidance, and finding a favorable abiotic environment (oxygen, temperature, etc.) in order to maximize their fitness. In the vertical water column of lakes with high solar ultraviolet radiation (UV) and invertebrate predators, zooplankton face two particularly strong and conflicting selective pressures. During daylight hours invertebrate predators often induce an upward vertical migration of zooplankton prey while potentially damaging UV forces a downward migration. We used 2.2 m long columns suspended vertically in a lake to conduct 2x2 factorial experiments to examine patterns of depth selection behavior by zooplankton in the presence and absence of both the invertebrate predator Chaoborus and UV. We hypothesized that Chaoborus and UV both affect the distribution of zooplankton and a combination of both factors would lead to a narrowing of depth distribution. We found that when Chaoborus were present zooplankton tended to be distributed at shallower depths in the columns, while in the presence of UV they exhibited a deeper distribution. Chaoborus themselves were always found near the bottom of the columns regardless of the UV treatment. Simultaneous exposure to predators and UV resulted in a peak of zooplankton (especially Daphnia catawba) distribution at intermediate depths. In a significant number of cases, depth range was narrowed in response to Chaoborus, UV, or both.
