Campanula versicolor is a constituent of the Campanula pyramidalis complex, distributed in the central and southern Balkan Peninsula with a small disjunct range in SE Italy. The taxonomy of the broadly defined C. versicolor was controversial in the past due to high morphological variability of the populations across the range. We used microsatellite DNA data along with morphometric analyses on an extensive population sampling covering the entire range to reconstruct the relationships among populations of the intricate C. versicolor s.l.

The evolutionary relationship between the base and face of the cranium is a major topic of interest in primatology. Such areas of the skull possibly respond to different selective pressures. Yet, they are often said to be tightly integrated. In this paper, we analyzed shape variability in the cranial base and the facial complex in Cercopithecoidea and Hominoidea. We used a landmark-based approach to single out the effects of size (evolutionary allometry), morphological integration, modularity, and phylogeny (under Brownian motion) on skull shape variability.

Feeding habits, diet overlap and morphological correlates of four juvenile species of the genus Diplodus were investigated during their settlement periods, along the Tyrrhenian coast. Stomach content analysis showed that the diets of D. sargus and D. puntazzo mainly comprised benthic prey such as harpacticoid copepods, amphipods and polychaetes. On the other hand, D. vulgaris and D. annularis fed mainly on planktonic prey such as ciclopoids, calanoids copepods and fish larvae. A biologically significant diet overlap, calculated using the Schoener index, was recorded between D.
