“…In that case, it is likely that migrating Chaoborus species will dominate those temporary ponds as a predator. Also, in lakes with few visual predators, Chaoborus species migrate to deeper depths throughout the day but can still exert a substantial predation pressure on zooplankton species at daytime (Berendonk and O'Brien 1996). In these systems zooplankton migration characteristics would conflict in the presence of the two opposite migrating requirements and may be confined to a narrow water layer to minimize predation and avoid damaging UV.…”

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

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.

“…For example, C. flavicans, a lake-dwelling species, exhibits diel vertical migration in response to the presence of fish (Dawidowicz 1990;Tjossem 1990). In contrast, the larvae of C. americanus, a pond-dwelling species, do not respond to chemicals from fish, whereas the larvae of C. punctipennis, a lake-dwelling species, do (Berendonk and O'Brien 1996). These results suggest that the larvae of lake-dwelling species, such as C. flavicans, have evolved a behavioral adaptation to the presence of fish, whereas the larvae of pond-dwelling species, such as C. crystallinus, have not evolved such an adaptation or have lost the response.…”

“…For the lake-dwelling species of Chaoborus, selection may occur at the larval stage, promoting alternative antipredator behaviors such as vertical migration and reduced movement frequency to avoid fish (Dawidowicz 1990;Berendonk and O'Brien 1996), assuming that fish predation is the ultimate cause for selective ovipositing and vertical migration in Chaoborus.…”

The phantom midge, Chaoborus, is a dipteran, the larvae of which occur in many freshwater habitats and are known to be vulnerable to predation by fish. The hypothesis was tested that ovipositing imagines of Chaoborus use chemical cues to detect predatory fish and avoid depositing eggs into waterbodies containing fish kairomones. The experimental setup consisted of cages with two small water‐filled plastic containers, in which Chaoborus imagines could oviposit. One container was connected to a flow‐through system holding fish kairomones, while the other container (the control) was connected to a flow‐through system without fish kairomones. Three different Chaoborus species were tested: two pond‐dwelling species, Chaoborus crystallinus and C. obscuripes, which do not coexist with fish, and a lake‐dwelling species, C. flavicans, which does coexist with fish. The imagines of the two pond‐dwelling species showed an ovipositing preference for fish‐free water. No significant difference in ovipositing preference was found for the lake‐dwelling species (C. flavicans). The present experiment suggests that in addition to direct predatory effects, adult oviposition behavior may contribute to the lack of local coexistence between fish and pond‐dwelling Chaoborus.

“…Other phantom midge species, such as Chaoborus crystallinus (Degeer), are rarely found in the presence of fish ( Borkent, 1981 ). Chaoborus species inhabiting fishless lakes have not evolved the vertical migratory defensive mechanism in response to fish chemicals and thus cannot coexist with fish ( Berendonk & O ' Brien, 1996 ). Furthermore, females of Chaoborus species found in fishless lakes avoid ovipositing in water that contains fish chemicals ( Berendonk, 1999 ).…”

Three mosquito species, Culex tarsalis Coquillett, Culex quinquefasciatus Say and Aedes aegypti L. (Diptera: Culicidae), were examined in laboratory binary choice experiments to investigate whether fish exudates from the mosquitofish, Gambusia affinis (Baird & Girard) (Cyprinodontiformes: Poecilliidae), deter oviposition and whether the responses of these mosquito species to fish exudates in oviposition sites are consistent with the risk of predation from fish experienced by each species in their respective natural breeding habitats. Culex tarsalis was deterred significantly from egg laying by the presence of fish exudates in oviposition cups, consistent with high levels of predation by fish in natural breeding sites. Egg laying by Cx quinquefasciatus was slightly reduced in water with fish exudates, but was not consistently deterred by water conditioned by mosquitofish, consistent with the species' relatively low risk of fish predation in natural habitats. Oviposition by container-breeding Ae. aegypti was not deterred by the presence of fish exudates in oviposition cups, consistent with a low risk of predation by fish in natural habitats.
