Measures of Niche Overlap, I [PDF]
Mathematical Medicine and Biology, 1986 Many methods of measuring niche overlap have been proposed, such as those of Renkonen, Morisita, and Horn. In this paper, conditions are put forward which overlap indices should reasonably be expected to satisfy. A general description of a good index is given, which covers as special cases those of the well-known indices which satisfy all the ...

Structural Network Properties of Niche-Overlap Graphs [PDF]
2013 International Conference on Signal-Image Technology & Internet-Based Systems, 2013 The structure of networks has always been interesting for researchers. Investigating their unique architecture allows to capture insights and to understand the function and evolution of these complex systems. Ecological networks such as food-webs and niche-overlap graphs are considered as complex systems. The main purpose of this work is to compare the

Measures of Niche Overlap, II [PDF]
Mathematical Medicine and Biology, 1986 In part I, see the preceding review, Zbl 0633.92017, a number of properties that a reasonable measure of overlap might be expected to possess are proposed in the form of axioms, and their motivations and consequences are also discussed from a biological viewpoint.

Niche Overlap as a Function of Environmental Variability [PDF]
Proceedings of the National Academy of Sciences, 1972 The relationship between environmental variability and niche overlap is studied for a class of model biological communities in which several species compete on a one-dimensional continuum of resources, e.g., food size. In a strictly unvarying (deterministic) environment, there is in general no limit to the degree of overlap, short of complete ...
