The Predatory Behavior of Dileptus anser*
The Journal of Protozoology, 1968SYNOPSIS. A motion picture study of the feeding behavior of Dileptus anser upon Colpidium campylum revealed that feeding begins shortly before dawn (about 4:30 a.m. Pacific DST in July and August) and continues until bright daylight, terminating sharply between 8:30 and 9:00 a.m. Little or no feeding occurs at any other time during a 24 hr cycle.

The day–night cycle is one of the strongest geophysical cycles modulating species’ behavioral rhythms. However, in deep-water continental margins, where light intensity decreases over depth, interspecific competition may alter behavioral responses to day–

Effects of Eltoprazine Hydrochloride on Predatory Behavior in Rats
The Psychological Record, 1991Treatment of rats with the potent antiaggressive compound eltoprazine hydrochloride (1.0 & 2.0 mg/kg) slowed both predatory attack and killing of frogs. These results demonstrate a specific predation-inhibiting action of the drug which is not obscured by the elements of conspecific aggression seen during muricide.

Relative importance of distance senses in hamster predatory behavior
Behavioural Processes, 1985This study examined the relative importance vision, audition and olfaction played in the localization of prey in the golden hamster (Mesocricetus auratus ). These three senses were blocked singly or in various combinations so that a hamster was tested under eight different situations with a tethered cricket and four situations with a dead cricket ...

Optimal diet theory: behavior of a starved predatory snail
Oecologia, 1987The tenets of optimal foraging theory are used to contrast the behavior of the predatory snail Acantina spirata when feeding on the barnacles Balanus glandula and Chthamalus fissus under conditions of satiation and starvation. As predicted in optimal diet models, A.

Seasonal Aspects of the Predatory Behavior of Loggerhead Shrikes
The Condor, 1980-Aspects of the foraging behavior of Loggerhead Shrikes were analyzed in the nonbreeding and breeding seasons in southern California. The birds obtained more food during the breeding season by attacking more often, not by taking larger prey. Attack rate during the breeding season was twice that in the nonbreeding period, with no apparent difference in ...
