Parasites that change predator or prey behaviour can have keystone effects on community composition Melanie J. Hatcher , 1, 2 Jaimie T. A. Dick , 3 and Alison M. Dunn 1 1 School of Biology, University of Leeds, Leeds, West Yorkshire, UK Many animals are predators, parasites or parasitoids, using other animals as food. They use a great diversity of hunting strategies and behaviours to capture or feed on their prey. Invertebrate predators, parasites and parasit ... Prey, predators, parasites. Green sunset. Vol. 1 | Adriana ... ... . Invertebrate predators, parasites and parasitoids play an important role in keeping many animal populations under control. Predator vs Parasite. Predators and parasites are two completely different ecological roles or niches. The differences are many between them, but in both predation and parasitism, one particular organism depends on another usually for food. Due to the diversity of parasites in prey species, the Carpinteria web had over twice as many predator-parasite as predator-prey links 1021 links compared with 505. Parasitic trematode worms having complex life cycles involving sequential infection of multiple hosts are involved in a large number of links in the Carpinteria Salt Marsh food web. In a third of the predator-parasite links in the Carpinteria Salt Marsh Web, parasites within prey are able to avoid digestion and exploit the predator as a host . The 'ghost of predation past' can therefore still be seen in the life cycles of trophically transmitted parasites, in which parasites that might have once been victims of predation now exploit their former predators as hosts ...

Thieltges6 1Ecology and Evolutionary Biology, University of Colorado, Ramaley N122, Campus Box 334, Boulder, CO 80309, USA Predation provides energy to prolong the life and promote the reproduction of the organism that does the killing, the predator, to the detriment of the organism being consumed, the prey. Figure 1 Historical trends in predator-prey and parasite-host ecology. (a) Disease ecology emerged as an important subdiscipline of ecology in the 1980 s and came to prominence in the 1990 s, nearly 20 years after predator-prey ecology. Data are proportions of papers published in selected ecological journals since 1950 whose titles included search terms related to disease ecology ... 1. Introduction. There is an increasing realization that parasitism can play as pivotal a role as predation in structuring biological communities, often via indirect interactions with non-host spec...
