Helminth communities of owls (strigiformes) indicate strong biological and ecological differences from birds of prey (accipitriformes and falconiformes) in southern Italy. [PDF]
We compared the helminth communities of 5 owl species from Calabria (Italy) and evaluated the effect of phylogenetic and ecological factors on community structure. Two host taxonomic scales were considered, i.e., owl species, and owls vs.

Scale and intensity of intertidal habitat use by knots Calidris canutus in the Western Wadden Sea in relation to food, friends and foes [PDF]
In August-October 1988-1992 we studied the distribution and abundance of knots Calidris canutus around Griend in the western Wadden Sea, and the extent to which these can be explained by benthic prey availability and presence of avian predators.

Molecular data support Bombus sonorus and Bombus pensylvanicus (Hymenoptera, Apidae) as distinct species [PDF]
Despite their distinctive banding patterns, setal coloration, and geographic ranges, the Sonoran bumble bee (Bombus sonorus Say, 1837) and the American bumble bee (Bombus pensylvanicus De Geer, 1773) are often treated as conspecific, with some ...
