ANDROMONOECY AND BUZZ POLLINATION IN SOLANUM SPECIES (SOLANACEAE) ENDEMIC TO THE CANARY ISLANDS


Role of specific quorum-sensing signals in the regulation of exopolysaccharide II production within Sinorhizobium meliloti spreading colonies.

BackgroundQuorum sensing (QS) in Sinorhizobium meliloti involves at least half a dozen different N-acyl homoserine lactone (AHL) signals.These signals are produced by SinI, the sole AHL synthase in S.meliloti Rm8530.The sinI gene is regulated by two LuxR-type transcriptional regulators, SinR and ExpR.Mutations in sinI, sinR and expR abolish the pro

Spatio-Temporal Dynamics of Field Cricket Calling Behaviour: Implications for Female Mate Search and Mate Choice.

Amount of calling activity (calling effort) is a strong determinant of male mating success in species such as orthopterans and anurans that use acoustic communication in the context of mating behaviour.While many studies in crickets have investigated the determinants of calling effort, patterns of variability in male calling effort in natural choru
