AB <p>Animals&rsquo; overlapping food chains influence the amount of energy &ndash; biomass that moves from one feeding level to the next. Dietary habits of red fox (<em>Vulpes vulpes</em>) and stone marten (<em>Martes foin</em>a) were studied in central Greece, using microscopic stomach analysis. Frequency of occurrence (FO) and relative volume (RV) were quantified. In order to study food niche overlap between two carnivores, the classical Pianka&rsquo;s index method and an alternative method of tree analysis were compared. Both methods showed a seasonal overlap, provided that RV was used in tree analysis as an influence variable.</p>
