Aim Climate is a major driver of large‐scale variability in biodiversity, as a likely result of more intense biotic interactions under warmer conditions. This idea fuelled decades of research on plant‐herbivore interactions, but much less is known about higher‐level trophic interactions. We addressed this research gap by characterizing both bird diversity and avian predation along a climatic gradient at the European scale. Loc...

Summary Strain HxN1, a member of the Betaproteobacteria , can grow anaerobically by denitrification with n ‐alkanes. n ‐Alkanes are apparently activated by subterminal carbon addition to fumarate yielding (1‐methylalkyl)succinates, the postulated enzyme being (1‐methylalkyl)succinate synthase (Mas). Genes encoding this enzyme ( mas ) were searched for via proteins that were specifically formed in n ‐hexane‐grown cells (in comp...
