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.

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.

The evolution of niche overlap and competitive differences [PDF]
Nature Ecology & Evolution, 2021 Competition can result in evolutionary changes to coexistence between competitors but there are no theoretical models that predict how the components of coexistence change during this eco-evolutionary process. Here we study the evolution of the coexistence components, niche overlap and competitive differences, in a two-species eco-evolutionary model ...

Niche Overlap Is Not Enough: Same Overlap, Contrasting Fluctuations. [PDF]
Ecol LettABSTRACT Niche overlap (NO) is a cornerstone of coexistence theory, summarising the strength of competitive coupling among species. Yet NO collapses distinct mechanisms into a single value and may miss key dynamical features. We quantify this limitation by examining temporal correlations in species abundances, a key out‐of‐equilibrium

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 ...

Modeling and Empirical Analysis of Regional Tourism Competitiveness Based on Niche Theory
Discrete Dynamics in Nature and Society, 2021 The fierce competition in tourism has brought a string of problems, such as the homogeneous development of regional tourism resources and the escalation of regional competition.
