Príklady prey

• An additive effect is when predation by two predators is equal to the sum of prey removed by each individual predator alone.

• Typically, an object of interest (such as a prey species) is of a different material than the background, and therefore it will affect light differently.

• Permanent lakes contain fish, which preferentially prey upon large individuals.

• The stems were prepared as described above, and infested with prey as for the mixed prey density treatment (iv) previously described.

• These findings indicate that the large ganglionic neurons are output neurons to the descending motor pathway for both prey catching and avoidance behavior.

• Observations on the vertical distribution of the biological control agents within substrate profiles, in the absence of prey, may be considered of limited value.

• Occasionally, we observed jumping spiders preying on marked flies shortly after release.

• Foraging on prey that are modified by parasites.

• Cats may acquire infection only when they begin to eat prey.

• It also produces a matrix with consumers (lizard species) as rows and proportional utilizations (pi) of prey by volume for each prey type as columns.

• Biological differences mirror differences in climate; the acutely developed senses of many species have adapted either for capturing prey or eluding predators, and so forth.

• Both species are highly suitable hosts for the parasite, and form the preferred prey for red foxes.

• The parameter represents the losses of prey not due to predation, and the product ac describes the asymptote of the hyperbolic response.

• At the end of the experiment, the fish and the vegetation were removed and left over prey items of the 2 classes were scored.

• Within an unknown time period, deer mice develop metacestode infections and eventually are preyed upon by foxes, the definitive host.
