Tibicinoides, with three small endemic California cicada species, has a confusing, intertwined systematic history Okanagana that we unravel here. An ingroup including all species of Tibicinoides and the majority (84.7%) were sampled for six gene regions, polarized Clidophleps, Okanagodes, Subpsaltria, Tibicina outgroups, subjected to Bayesian phylogenetic analysis. Although was monophyletic fro...

The chemical composition of the volatile metabolites of Crithmum maritimum harvested from several geographic localities along the Mediterranean coasts was studied by GC and GC-MSD. The major oil constituents were found to be dillapiole, gamma-terpinene, sabinene, limonene and beta-phellandrene. The Western populations were richer in dillapiole, whereas the Southern collections were characterize...

The usual evolutionary and ecological approaches to foraging in social insects often lack an investigation at the level of both individual behavioural complexity and social mechanisms ruling the emergence of adaptive collective strategies. The prey scavenging behaviour of the dimorphic ant Pheidole pallidula was used in this study to investigate (1) how individuals estimate the size of prey, (2...
