We examined 181 skulls of crested porcupine Hystrix cristata Linnaeus, 1758 from Sicily, mainland Italy, and from several African countries. Two skulls, both from Sicily, had anomalous dentition. One skull exhibited a case of supernumerary dentition, whereas the other one showed a dental malformation with numerary teeth reduction. The type of anomaly was determined in each skull examined and some hypotheses for explaining these anomalies were presented.

This paper reports the findings of a study on the spacing pattern of a population of weaselsMustela nivalis Linnaeus, 1758 in central Italy. We describe this pattern at spatial and habitat level, meant as a set of vegetational and environmental features. The study area is a typical agricultural landscape, consisting of highly fragmented natural habitat modified by thousands of years of human presence and work. The results indicate that individual home ranges vary greatly from non breeding to breeding season: during spring and summer, weasels increase their movements and the number of tracts they cross, which results in home range areas up to 10 times larger. Moreover this study demonstrates a strong preference of weasels for habitats formed by natural residual edges between fields and meadows. The shapes of the individual home ranges follow these edges, producing a typical linear spatial home range pattern.
