“…The cost-effectiveness of competition for resources generally falls as they are accumulated: for instance a poorly fed animal has more to gain by competing for food than one on a good diet, as experimental ev idence shows (Wise and Zimmerman, 1973).

“…Increases in emotionality are more consistent (Slocum, 1976;Zimmerman et al, 1974;Zimmermann, Steere, Strobe], & Hom, 1972) as are feeding abnormalities (Hill & Riopelle, 1975 ;Hillman, FuseIier, & Riopelle, 1974;Kerr & Waisman, 1970). The primates are characterized as nervous and neophobic, avoiding novel objects and playful partners, responding often with fear or hostility, and being engaged in excessive amounts of self-stimulation (Slocum, 1976;Wise & Zimmermann, 1973;Zimmermann et al, 1972Zimmermann et al, , 1974Zimmermann et al, , 1970. These differences have not been found in primates whose mothers were malnourished during pregnancy (Riopelle, Hale, & Hill, 1976).…”

Forty-seven monkeys were fed 1 of 8 diets between the ages of 1 and 7 months containing full-, half-, or quarter-strength protein or protein and calories using either casein or soy protein. While on the diet, malnourished infants were inactive both socially and nonsocially. When returned to a normal diet, previously malnourished subjects were more agonistic towards familiar peers but more friendly and less agonistic when later paired with unfamiliar monkeys. The data suggest that short periods of early severe malnutrition may protect the individual against adverse social conditions (e.g., isolation) and delay the development of normal social skills.

“…Effects of starvation on dominance have been documented for a variety of animals (Bruce 1941 ;Hazlett 1966;Nowlis 1941;Wise and Zimmerman 1973). In our experimental system a given quantity of food will not be of different value to contestants because of differences in their levels of starvation ; both adults and juveniles can gain their total daily requirements within a few hours of intrusion time (Ewald, to be published).…”

During the nonbreeding season, adult Anna and black-chinned hummingbirds (Calypte anna and Archilochus alexandri) have lower defense costs and more exclusive territories than juveniles. Adult C. anna are victorious over juveniles in aggressive encounters, and tend to monopolize the most temporally predictable resources. Juveniles are more successful than adults at stealing food from territories (the primary alternative to territoriality), presumably because juveniles are less brightly colored. Juveniles have lighter wing disc loading than adults, and consequently should have lower rates of energy expenditure during flight. Reduced flight expenditures may be more important for juveniles because their foraging strategy requires large amounts of flight time. These results support the contention of the asymmetry hypothesis that dominance can result from a contested resource being more valuable to one contestant than to the other. Among juveniles, defence costs are also negatively correlated with age and coloration; amount of conspicuous coloration is negatively correlated with the number of bill striations, an inverse measure of age.
