Genet (Genetta genetta L., 1758) diet shift in mountains of central Spain

Abstract:

This study focuses on the seasonal shill of the main prey and patterns of prey size consumed by a population genet (Genetta genetta L.) in central Spain as determined by scat analysis. Four different 'middens' (186 seats) were studied. Data were presented as frequency of occurrence and biomass of each prey group considered. Seasonal variation for the occurrence of each prey group in the diet was tested with the Chi-square goodness of fit test. Mean prey size index was used to analyse the distribution pattern of prey weights consumed. The mean prey size obtained was compared with others from different areas. As in earlier studies, woodmouse (Apodemus sylvaticus) was the predominant prey group. However, in winter the diet was based on birds. In addition, this group was the most important throughout the year with respect to frequency of occurrence data. This shift is discussed from an energetic point of view. The role of dung beetles was also significant and their inclusion in mean prey size calculations was recommended. The remaining groups only showed unimportant seasonal fluctuations. Mean prey size obtained is lower than in other populations. The relative role of woodmouse, arthropods and rabbits (Oryctolagus cuniculus) explains these differences.
