Document Summary
Interactions between species that enhance the fitness of one individual while reducing the fitness of the exploited individual: one organism makes its living at the expense of another. 14. 1 exploitative interactions weave populations into a web of relationships that defy easy generalization. Parasites that alter the behavior of their host: cordyceps sp, parasitic fungus, example. Complex exploitative interactions can alter relationships among organisms and their environment. Parasite mediated complex exploitative interactions can affect: fecundity, mortality, demography, population abundance, population dynamics. 14. 2 predators, parasites, and pathogens influence the distribution, abundance, and structure of prey and host populations. The picture above depicts some exploitative interactions between algae and h. borealis. Exploitative interactions can have cascading effects throughout an ecosystem. The network of relationships among organisms is extensive and complex. Exploitative interactions between two organisms can lead to cascading effects on other organisms throughout the ecosystem. Picture below shows the effect of an outbreak that affected foxes.
