본문내용

1) studies included by food-web frame work
(1) habitat heterogeneity and the regulation of community structure
(2) environmental change through time and community structure and function
(3) productivity gradients and community structure
(4) direct and indirect cascading effects of predation on community structure
(5) intraguild predation
(6) indirect mutualism
(7) apparent mutualism
(8) ecosystem stability and nutrient dynamics

- limitation of most food web studies
(1) some population interactions cannot be fully evaluated,
because their outcomes can be modified by other members of the web.
(2) most food-web studies have viewed consumption exclusively within pathways

2) several theoretical debates on food webs
(1) paradigms associating complexity with stability
(2) hypotheses relating the effects of size-dependent predation to community structure
3) requirement for food web structure
3) food web structure on request in
(1) solving a number of problems in resource management
(e.g. pest control, environmental contamination, fisheries management, bioremediation of lakes)
(2) giving basic knowledge of community structure and population interaction
(e.g. agroecosystems may be influenced by the response of predators to nontarget prey, or by predator-predator interference)
