The predatory behavior of Mesocyclops edax: Predator preferences, prey defenses, and starvation-induced changes1
The predatory behavior of field-collected Mesocyclops edax on four different kinds of prey was compared under similar and different predator starvation regimes. Unstarved Mesocyclaps did not consume either the ciliate Rhabdostyla or the cladoceran Bosmina. Increasing starvation in the predator increased the probability of ingestion after encounter for both of these prey. The rotifer Asplanchna ...
متن کاملSelective predation by benthivorous fish on stream macroinvertebrates – The role of prey traits and prey abundance
25 The prey selectivity of fish depends largely on traits of prey and predator. Preferable prey 26 traits might be different for visual predators (such as drift-feeding salmonids) and rather non27 visual predators (such as benthic feeders). We evaluated the explanatory power of five prey 28 traits and prey long-term abundance for the prey selection of small benthivorous fish by 29 analysing the...
متن کاملIncreased predation of nutrient-enriched aposematic prey
Avian predators readily learn to associate the warning coloration of aposematic prey with the toxic effects of ingesting them, but they do not necessarily exclude aposematic prey from their diets. By eating aposematic prey 'educated' predators are thought to be trading-off the benefits of gaining nutrients with the costs of eating toxins. However, while we know that the toxin content of aposema...
متن کاملAquatic predation alters a terrestrial prey subsidy.
Organisms with complex life histories (CLH) often cross habitat or ecosystem boundaries as they develop from larvae to adults, coupling energy flow between ecosystems as both prey (bottom-up) and consumers (top-down). Predation effects on one stage of this life cycle can therefore cascade across ecosystems, magnifying the impact of local predation. The majority of predation studies have assesse...
متن کاملPredation risk causes oxidative damage in prey.
While there is increasing interest in non-consumptive effects of predators on prey, physiological effects are understudied. While physiological stress responses play a crucial role in preparing escape responses, the increased metabolic rates and shunting of energy away from other body functions, including antioxidant defence, may generate costs in terms of increased oxidative stress. Here, we t...
