摘要: One of the primary channels sensory input for zooplankton are chemical signals. Much behavior is triggered by stimuli, including feeding, predator defense, mating, and migration. Chemically regulated affects larger scale ecosystem processes like grazing, recruitment secondary production. Knowledge how chemicals transmit information about location, food quality, conspecifics, competitors, predators critical understanding aquatic ecosystems function. This paper reviews behavioral evidence that planktonic rotifers respond to a variety stimuli. Although rich rotifer behaviors signals, little progress has been made isolate characterize these If ecology become predictive science, knowledge mechanisms causing observed interactions necessary. Chemical signals need be isolated, purified, characterized, their causal role in regulating population community needs demonstrated. Rotifers have chemosensory neurons corona electron microscopy revealed chemoreceptive pores anterior integument several species. Some use chemoreceptors discriminate particles based on flavors cell surface. In Asplanchna, prey discriminated contact chemoreception. Asplanchna releases waterborne signal induces spine formation Brachionus species, Keratella cochlearis, K. slacki, Filinia longisecta. The colonial Sinatherina socialis defended against fish predation warts containing unpalatable yet identified. Larval settlement Collotheca gracillipes determined chemistry plant surfaces. Larvae prefer undersurface leaves where there low Ca++ microhabitat due photosynthesis. Oviposition Euchlanis dilatata restricted surfaces familiar maternal female. Hydrogen peroxide certain prostaglandins stimulate resting egg hatching even dark. Sexual reproduction polymorphism sieboldi dietary tocopherol.

Unknown compounds produced bacteria also mixis 4–10 fold over Mate recognition B. 29 kD surface glycoprotein called mate pheromone (MRP). MRP polyclonal antibody it prepared. structure oligosaccharide protein components currently being characterized. Elucidation life cycles will make important contributions ecological communities.
