Three recently discovered quantitative empirical generalizations describe major features of the structure of community food webs. These generalizations are: (i) a species scaling law: the mean proportions of basal, intermediate and top species remain invariant at approximately 0.19, 0.53, and 0.29, respectively, over the range of variation in the number of species in a web; (ii) a link scaling law : the mean proportions of trophic links in the categories basal-intermediate, basal-top…

A stochastic theory of community food webs II. Individual webs
TLDR
It is demonstrated that the ratio of links to species shows no pronounced increasing or decreasing trend, but varies substantially, over the observed range of variation in the number of species in a web.
QUANTITATIVE PATTERNS IN THE STRUCTURE OF MODEL AND EMPIRICAL FOOD WEBS
TLDR
It is demonstrated that the quantitative unifying patterns that describe the properties of the food-web models considered earlier also describe the majority of the empirical webs considered, and that the empirical distributions of number of prey and number of predators follow universal functional forms that match the analytical predictions.
Scaling from individuals to networks in food webs
TLDR
Paying greater attention to both the similarities and differences between the two types of models will be better able to demonstrate the ecological insights offered by phenomenological models, and will help to understanding the true origins of food-web structure.
A Stochastic Theory of Community Food Webs. V. Intervality and Triangulation in the Trophic-Niche Overlap Graph
TLDR
The broad ecological interpretation of the findings is that the larger the number of species in a community, the less likely it is that a single dimension suffices to describe the community's trophic-niche space and the more likely that there are no "homological holes" in the overlap graph and resource graph.
Extinction of Species Due to Deterministic and Stochastic Interactions in Food Webs
Previous research on the extinctions that occur in niche model food webs with deterministic and stochastic dynamics has shown that the structure of the food web can play an important role in
Nonlinear scale dependence and spatiotemporal variability in planktonic food webs
Zooplankton food webs of Lake Okeechobee, Florida, were analyzed in order to examine spatiotemporal variability and test for scale dependence of major food web properties. 46 webs were constructed
A stochastic theory of community food webs. III. Predicted and observed lengths of food chains
This paper offers a quantitative theory of the length of food chains. The theory derives from a mathematical model of community food webs called the cascade model. The paper tests the predictions

TLDR
Regularities in the numbers and kinds of trophic links in community food webs are described and explained to show how linear relationships, and scale-invariance in the proportions of basal, intermediate, and top species, make it possible to predict with remarkable precision the proportions.

TLDR
It is shown that within habitats of a certain limited physical and temporal heterogeneity, the overlaps among niches, along their trophic dimensions, can be represented in a one-dimensional niche space far more often than would be expected by chance alone and perhaps always.
Environmental Control of Food Web Structure
The structure of 40 real food webs, representing aquatic and terrestrial communities from all latitudes, is found to be markedly affected by the degree of variability of the physical environment. In
Ratio of prey to predators in community food webs
WHETHER the diversity of resources limits the diversity of consumers, and specifically, whether the number of kinds of prey limits the number of kinds of predators, has been of continuing interest in
Community food webs have scale-invariant structure
TLDR
In biological communities, the proportions of top, intermediate and basal species are, on average, independent of the total number of species, so there is a direct proportionality between the numbers of prey and predators.
