Evolution - predator / prey interactions

WebIn evaluating predator-prey interactions, both the predators and prey have physiological and behavioral characteristics that must be considered. Major predator characteristics that can be evaluated include: (1) visual, mechanical, or chemical detection of prey; (2) how much energy is required during searching for and attacking prey; and (3 ... WebParasite/host interactions Predator/prey interactions Symbiosis Mutualisms However, tight interspecific interactions do not always lead to coevolution. Mimicry, for example, can be a parasite/host interaction (in Batesian mimicry) or a mutualism (Müllerian mimicry, see earlier lecture). Mimicry creates exactly the kinds of ties

WebPopulation sizes of predators and prey in a community are not constant over time, and they may vary in cycles that appear to be related. The most often cited example of predator-prey population dynamics is seen in the cycling of the lynx (predator) and the snowshoe hare (prey), using 100 years of trapping data from North America (Figure 19.13 ... WebPredator assays To understand how prey phenotypes are shaped by interactions with predators, we must study predator responses to different prey. We focus on avian predators and run experiments asking birds which types of prey they can find and are willing to eat. These experiments take place at Lammi Biological Station, where the new bird…

WebHence, within this genus, the evolution of cooperation would not provide access to otherwise inaccessible, large prey. Instead, we show that social Stegodyphus spiders are smaller than their subsocial counterparts, while catching similar sized prey, leading to the predicted increase in prey-predator size ratio with sociality.
