Either way, Predators are using humans for more than just a challenging hunting trip, but as a way to learn martial arts and fighting styles that make the Predator species that much more dangerous. Predators either abduct humans they wish to learn from to then hunt them in a controlled environment later, or they stalk them and hunt them outright on Earth. Both of these mechanisms can reduce prey extinctions and. This is why Predators are so obsessed with hunting humans, not because they’re the strongest or even the deadliest prey (especially next to some of the Predator’s other prey, like Xenomorphs), but because humans have the most to teach the Yautja at every encounter. The presence of other species in the community, can lead to prey switching by predators (Vallina et al., 2014) while unpalatable non-prey species have been shown to reduce consumption rates and alter the shape of functional responses (Kratina et al., 2007 Hammill et al., 2015b). Increasing species number (a) increases drought resistance high resistance. Each predator consumes a fixed number of prey in a given. However, it wasn’t until this point in Predator canon that it was confirmed that Predators actively learn the fighting styles and techniques from the prey they hunt - predominantly humans. Predator-Prey Theory and Variability Peter Chesson Annual Review of Ecology. Predatorprey relationships traditionally have been interpreted purely based on taxonomy, that is, which species consumes which species. Under such circumstances, the predators do NOT interfere with one another and predators never get full. Predatorprey interactions are central in understanding the mechanisms behind food web dynamics, and genetic variation in both predators and prey could largely explain these dynamics. The prey populations are dependent on the predator population, because their death rate is dependent on the number of prey that are eaten by predators in a. Practically every chapter in Predator lore before this point implied that Yautja seek out increasingly deadly prey in order to hunt them using their own culture’s training and fighting styles, thereby proving themselves superior to any alien life form they come across. Food webs are networks of interacting species that feed on each other. Top-down control occurs when the population density of a consumer can control that of its resource, for example, predator populations can control the abundance of prey species (Power 1992).
