   Ecological disturbances affect interspecific interactions and, consequently, community dynamics 1, 2. Trophic interactions also play a crucial role in community dynamics as predators shape prey communities by affecting the strength of species interactions 3 – 13. However, there is a lack of studies on the combined effects of disturbances and ...

   Jun 10, 2019 · Invading predators can devastate an ecosystem. In fact, a leading cause of extinction is the introduction of predators into an isolated system like an island or a lake. The destruction is usually blamed on the predator’s eating choices, but sometimes the key lies in the prey animals’ responses, according to an international team of ...

   Oct 1, 2010 · 5.1. Recommendation 1: use realistic patterns of extinctions within trophically-diverse communities. Almost by definition, predator diversity studies directly address the second of these suggestions, by considering effects that span several trophic levels (predators and prey, and often predators, prey and plants).

   Does a community of predators exert a positive diversity effect?

   • Wilby and co-authors (2005) found that a community of predators exerted positive diversity effects when attacking a prey species with complex development and thus morphologically very different life stages, but not for a prey species with simple development where all stages were morphologically similar.

   Does predator diversity affect prey abundance?

   • Finally, when herbivores respond behaviorally to the threat of predation, predator diversity may significantly impact the abundance or diversity of primary producers despite the lack of an effect on prey abundance (Bruno and O’Connor, 2005, Byrnes et al., 2006). 5. Are predator diversity studies particularly relevant to conservation?

   Do predators have emergent diversity effects?

   • More common is the case where predators have effects that are independent but functionally diverse. In this scenario, predators may differ in their absolute attack rates and other measures of prey capture efficiency, but species do not interact when embedded within diverse communities to yield emergent diversity effects.

   How do predators affect prey populations?

   • That is to say, predators consume prey, and by reducing prey numbers, have cascading and sometimes large effects upon communities. Recent studies however have shown that predators also affect prey populations through non-lethal or non-consumptive means. In these situations, predators alter prey behavior, morphology, and/or habitat selection.

   Why are predator Diversity Studies important?

   • Predator diversity studies are particularly relevant to conservation because they focus on the trophic group that is most prone to extinction, and because they nearly always measure diversity effects that span several trophic levels.

   Why do predators occupy unique feeding niches?

   • Predators that occupy unique feeding niches by attacking different prey species, attacking prey in different habitats, and/or foraging at different times of the day or year are particularly likely to exert complementary impacts on prey (Casula et al., 2006).

    eralist predators on a-diversity produces an increase in ß-diversity, because the diversity of the region (y-diversity) is determined by the species pool. In other words, general-ist predators reduce the community size of their prey, and thus increase the degree to which stochasticity contrib-utes to local community assembly (Orrock and ...
