Figure 1From: A global overview on the diet of the dice snake (Natrix tessellata) from a geographical perspective: foraging in atypical habitats and feeding spectrum widening helps colonisation and survival under suboptimal conditions for a piscivorous snake Number and frequency of prey species in the diet of Natrix tessellata in different habitats. Invertebrates were united into one group due to their low number and similar distribution. Code of categories: H-1: marine, H-2: freshwater, H-3: terrestrial, F-1: no quantitative data, F-2: rare, F-3: frequent, F-5: common.Back to article page
