dc.description.abstractIntraguild predation systems describe food webs in which an omnivorous predator competes with an intermediate prey for a basal resource. The classical intraguild predation system with Holling type II predation terms has the limitation of not being able to reproduce coexistence between predators in resource-rich environments despite its ubiquity in ecological systems. In this study, adaptive predator-induced and fitness-dependent defense of the intermediate predator is included into the model. In contrast to previous studies, this is done without an artificial bounding term. Numerical bifurcation software is used to show that adaptive defense mechanisms can significantly enhance parameter regimes leading to coexistence. Two different adaptation parameters are distinguished and linked to adaptations under different environmental conditions. The results indicate that the form of the reactivity-accuracy trade-off depends on the state of the environment. Finally, it is shown that an impact of adaptivity on dispersal abilities can considerably change shape and speed of invasion waves on a one-dimensional domain, which is important as those are the main measurable variables when examining data from biological invasions. The results indicate that a locally perfectly adaptive system can be globally (transient) maladaptive.
