Understanding how niche-based and neutral processes contribute to the spatial variation in plant–pollinator interactions is central designing effective pollination conservation schemes. Such schemes are needed reverse declines of wild bees other pollinating insects, promote services cultivated plants. We used data on bee with plants belonging four tribes Loteae, Trifolieae, Anthemideae either s...

Phylogenetic relationships among genera of the subtribes Sonchinae (11 genera and ca. 130 species) and Dendroseridinae (2 genera and 12 species) sensu Bremer were assessed with ITS and matK gene sequences. The Sonchinae is strongly supported as paraphyletic, and subtribal rank of Dendroseridinae is poorly supported. This study re-delimits Sonchinae, which now includes 14 genera and ca. 146 spec...

It is shown that the concept of the Iranian endemic Lactuca polyclada in the sense of both its original author Boissier and its current use actually admixes two entirely different species, as was first noted by Beauverd a hundred years ago but has been neglected by later workers. One is a putative relative of Lactuca rosularis, the other was recognised by Beauverd as a member of the genus Cicer...
