From Elton to Mathematics and Back Again

  author={David G. Raffaelli},
  pages={1035 - 1037}
Food webs can be thought of as intricate spider webs that despite their complexity remain stable. In his Perspective, Raffaelli discusses a new mathematical analysis ( Neutel et al.) that reveals how even the most complex food webs retain their stability by having many weak interactions between species in their long loops. 
Where are the parasites in food webs?

This review posits that the methods, directions and questions in the field of food web ecology are not always congruent with parasitological inquiry, and asserts that more effort must be focused on parasite-centric models. Expand
Food Webs for Parasitologists: A Review
  • M. Sukhdeo
  • Biology, Medicine
  • The Journal of parasitology
  • 2010
To make significant contributions to the food web debate, parasitologists must work from the standpoint of natural history to elucidate patterns of biomass, species abundance, and interaction strengths in real food webs, and these will provide the basis for more realistic models that incorporate parasite dynamics into the overall functional dynamics of the whole web.

Manipulating Interaction Strengths and the Consequences for Trivariate Patterns in a Marine Food Web
The importance of allometric relationships and size-structuring in natural communities as a means of preserving food web structure and sustainability, despite significant changes in the diversity, stability and productivity of the system is revealed. Expand
Limits on ecosystem trophic complexity: insights from ecological network analysis.
It is suggested that several whole-system processes may be at play in generating these ecosystem limits and regularities, and an upper bound on the number of effective trophic levels at about 3-4 links is suggested. Expand
Compartments revealed in food-web structure
It is shown that a method for detecting compartments from the social networking science identified significant compartments in three of five complex, empirical food webs. Expand
Eelgrass (Zostera marina) Food Web Structure in Different Environmental Settings
The differences in meadow and food web structure of the two seagrass habitats, suggest how physical setting may shape ecosystem response and resilience to anthropogenic pressure. Expand
Efficiency of transfer of essential polyunsaturated fatty acids versus organic carbon from producers to consumers in a eutrophic reservoir
The trophic pyramid concept, which implicitly implies that all the energy-yielding compounds of carbon are transferred from one Trophic level to the next with the same efficiency of about on average 10%, should be specified for different carbon compounds. Expand

Stability in Real Food Webs: Weak Links in Long Loops
It is shown and explained mathematically that patterning enhances stability, because it reduces maximum “loop weight” and thus reduces the amount of intraspecific interaction needed for matrix stability. Expand

Weak trophic interactions and the balance of nature
The results show that weak to intermediate strength links are important in promoting community persistence and stability, and data on interaction strengths in natural food webs indicate that food-web interaction strengths are indeed characterized by many weak interactions and a few strong interactions.

Complex Trophic Interactions in Deserts: An Empirical Critique of Food-Web Theory
  • G. Polis

  • 1991
It is argued that most cataloged webs are oversimplified caricatures of actual communities, and patterns from food webs of real communities generally do not support predictions arising from dynamic and graphic models of food-web structure. Expand
Energetics, Patterns of Interaction Strengths, and Stability in Real Ecosystems
The results show that energetics and community structure govern ecosystem stability by imposing stabilizing patterns of interaction strengths. Expand
Fundamentals of Ecology
Eugene P. Odum explores the basic concepts involved in forging a discipline out of the varied data going into the field of ecology, and tries all too briefly to list those rules essential to survival of man in an environment that is at least minimally human. Expand
