Feeding Preferences of the Italian Roe Deer (Capreolus capreolus italicus Festa, 1925) in a Coastal Mediterranean Environment.

The present study was aimed to deepen the knowledge on diet and on feeding preferences of the Italian roe deer. The research was carried on in the Castelporziano Presidential Estate, a protected area of Latium coast. Quadrat method was used to assess plant frequency, whereas diet composition was determined by fecal micro-histological analysis. A total of 143 plant species were identified in the site and 109 of them were found in the feces of the Capreolus capreolus italicus. All over the year, most of the taxa were ingested in low percentages (≤5%) and the most utilized plant species were Quercus suber, Prunus spinosa, Rubia peregrina, and Crateaegus monogyna. Fagaceae and Rosaceae plant families represented the bulk of the diet and were positively selected. In addition, a positive selection on Fabaceae and Oleaceae families was found in wet season but not in dry one. In both periods the Italian roe deer showed a positive selection for deciduous woody plants and evergreen woody plants, instead avoided wild forbs and wild graminoids. Our results confirmed that this subspecies behaved as a generalist highly selective feeder.
