BMC Genomics, 2009 Background Two major biological stressors of freshwater zooplankton of the genus Daphnia are predation and fluctuations in food quality. Here we use kairomones released from a planktivorous fish (Leucaspius delineatus) and from an invertebrate predator ...

Influence of fish kairomones on the ovipositing behavior of Chaoborus imagines [PDF]
Limnology and Oceanography, 1999 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.

Fate of Planktothrix-derived toxins in aquatic food webs: A case study in Lake Mindelsee (Germany)
Ecotoxicology and Environmental SafetyBlooms of the red, filamentous cyanobacterium Planktothrix rubescens occur frequently in pre-alpine lakes in Europe, often with concomitant toxic microcystin (MC) production.

Knowledge and Management of Aquatic Ecosystems, 1996 Vingt mille larves de brochet (Esox lucius, L.) ont été élevées 35 jours en bac, avec une nourriture vivante (zooplancton et larves de Chaoboridés, Diptères) collectée en lagune d'épuration. Le but de cette expérience était de connaître l'influence de la

Chaoborus Punctipennis and Chaoborus Albatus: Influences of Fish Communities and Abiotic Factors
Chaoborus punctipennis Say and Chaoborus albatus Johnson are phantom midges with coexisting small transparent aquatic larvae that exhibit daily vertical migrations and occur in lakes with fish. We hypothesized that these species differ in their habitat preference as suggested by the principle of competitive exclusion and that fish predation affects ...

Permafrost thaw lakes and ponds as habitats for abundant rotifer populations
Arctic Science, 2018 Thermokarst lakes and ponds were sampled across a range of permafrost landscapes in subarctic Québec (Nunavik, Canada) to compare their rotifer and other zooplankton characteristics with a set of rock-basin lakes and ponds in the region.
