Motile bacteria respond to attractants and repellents in their environment by changing their movement. Stock et al. describe the similarities of the bacterial chemotaxis signaling system to eukaryotic signaling cascades. Also included is a discussion of how the ordered signaling complex of the receptor, the kinase CheA, and the kinase regulator CheW can be thought of as a primitive "probrain" t...

Premise of research. Brood-site deceptive flowers use dishonest signals—especially floral odors that mimic oviposition substrates—to attract and deceive saprophilous insects to pollinate them. In this work, we recorded the pollinators of the sapromyiophilous species Jaborosa rotacea (Solanaceae) endemic to southern South America. Then, we characterized the floral volatiles of this species, and ...

The attraction of female tabanids to Malaise traps and canopy traps baited with aged horse urine, 1-octen-3-ol, or a combination of aged horse urine and acetone was studied in the Kopacki rit Nature Park in Eastern Croatia. Malaise traps captured very few tabanids relative to canopy traps. The number of females of Tabanus tergestinus and Haematopotapluvialis collected from 1-octen-3-ol baited c...
