(1) We recognize that this single test may reflect the total effect of several behavioral traits.(2) Procedures used in behavioral experiments have been described in detail elsewhere.(3) Food in the stomach does not appear to alter the kinetics or behavioral effects of the medication.(4) Only one pair was observed at a time in order to time behavioral patterns precisely.(5) The social and behavioral goals that we achieved were beyond our hopes and imagination!(6) Indeed, the interplay between prey and predator is a central theme of behavioral ecology.(7) Our suspicion in that we might see effects in a different behavioral context.(8) Prey show the same response, regardless of the behavioral state of the predator.(9) Autonomic responses are among the richest sources of adaptive behavioral patterns.(10) New research is also connecting heart problems to behavioral patterns and social conditioning.(11) At the start, males usually called and displayed behavioral threats to each other.(12) It is in this context that we began our studies of behavioral choice in the leech.(13) The entire behavioral record for each ape was scored independently by two observers.(14) Second, this fear of a specific concrete object allowed use of a behavioral approach test.(15) But many people so diagnosed do not show such abnormalities, and many people who are behaviourally not violent do show them.(16) Lions in zoos are behaviourally quite a different matter, as you'd know: they're a social animal, they'll lie or eat and they'll play with each other and they work very well.
