An Empirical Evaluation of the Utility of Convex Hull and Standard Ellipse Areas for Assessing Population Niche Widths from Stable Isotope Data
Stable isotope analyses are increasingly employed to characterise population niche widths. The convex hull area (TA) in a δ(13)C–δ(15)N biplot has been used as a measure of isotopic niche width, but concerns exist over its dependence on sample size and associated difficulties in among-population com...
