Morphometrical methods as tools for identifying field maple (Acer campestre L.) trees
Several morphometrical methods were evaluated with the purpose of distinguishing individual maple trees by their samaras and to reveal shape trends. Landmarks for geometric morphometrics gave 97–98% correctly classified trees in a jackknifed confusion matrix from discriminant analysis, fan-positioned landmarks and semilandmarks 92%, linear data 79% and elliptic Fourier analysis 65% correctly class
