Detrended Correspondence Analysis of Dietary Data

摘要: Abstract Niche relationships of fishes can be inferred from dietary analysis. Individual fish and their prey ordered along an underlying continuum that has ecological relevance, The specific arrangement is a function the predator's behavior prey's spatial distribution. This distribution eaten by predators conforms to assumptions detrended correspondence multivariate technique, designed specifically for discrete data, uncovers resource gradients in data. We used it analyse information collected banded sunfish Enneacanthus obesus bluespotted gloriosus compared then results with analyses discriminant analysis, factor principal component Detrended analysis was as effective discriminating among species on basis diet much better than either or produci...
