Niche width and overlap pdf
This measure ranges between 0 no overlap and 1 complete overlap, so 0. We investigated the niche breadth and overlap of the fish species occurring in four environments affected by the Coaracy Nunes reservoir, in the Amapá.Individual foraging specialization: niche width versus niche overlap.

متن کاملNiche overlap and diffuse competition.
Current theory predicts a distinct upper limit on the permissible degree of niche overlap; moreover, theory suggests that maximal tolerable overlap should be relatively insensitive to environmental variability. Data presented here demonstrate that, within the lizard subset of natural desert communities, niche overlap decreases both with increasing environmental variability and with increasing n...
متن کاملIndividual foraging specialization: niche width versus niche overlap
A recent review of individual specialization suggests it is widespread and has important implications for conservation, ecology and evolution (Bolnick et al. 2003). Dozens of studies have identified ‘‘individual foraging specialization’’ in a variety of species, yet upon closer examination these studies differ markedly in how they define and quantify specialization. Given such diverse approache...
متن کاملDistance and cosine measures of niche overlap
Niche overlap is increasingly used as a way of measuring the intensity of interorganizational competition. This paper examines and compares various distance and cosine measures of niche overlap. The analysis in this paper shows that Euclidean distance applied to the raw data as well as to transformed data is not an appropriate measure of niche overlap. An alternative measure from the cosine fam...
متن کاملNiche overlap as a function of environmental variability.
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 congruence. However, in a fluctuating (stochastic) e...
