Title (up) Complementary hemispheric specialization in monkeys Type Journal Article
Year 1988 Publication Science Abbreviated Journal Science
Volume 242 Issue 4886 Pages 1691-1694
Keywords
Abstract Twenty-five split-brain monkeys were taught to discriminate two types of visual stimuli that engage lateralized cerebral processing in human subjects. Differential lateralization for the two kinds of discriminations was found; the left hemisphere was better at distinguishing between tilted lines and the right hemisphere was better at discriminating faces. These results indicate that lateralization of cognitive processing appeared in primates independently of language or handedness. In addition, cerebral lateralization in monkeys may provide an appropriate model for studying the biological basis of hemispheric specialization.

Title (up) Cooperative Hunting Harris' Hawks (Parabuteo unicinctus) Type Journal Article
Year 1988 Publication Science Abbreviated Journal Science
Volume 239 Issue 4847 Pages 1525-1527
Keywords
Abstract Coordinated hunting by several individuals directed toward the capture and sharing of one Large prey animal has been documented convincingly only for a few mammalian carnivores. In New Mexico, Harris' hawks formed hunting parties of two to six individuals in the nonbreeding season. This behavior improved capture success and the average energy available per individual enabled hawks to dispatch prey larger than themselves. These patterns suggest that cooperation is important to understanding the evolution of complex social behavior in higher vertebrates and, specifically, that benefits derived from team hunting a key factor in the social living of Harris' hawks.

Title (up) Does Biology Constrain Culture? Type Journal Article
Year 1988 Publication American Anthropologist Abbreviated Journal Am Anthropol
Volume 90 Issue 4 Pages 819-831
Keywords models, learning, evolution, culture, fitness, adaptive, environment, human, natural selection, behavior
Abstract Most social scientists would agree that the capacity for human culture was probably fashioned by natural selection, but they disagree about the implications of this supposition. Some believe that natural selection imposes important constraints on the ways in which culture can vary, while others believe that any such constraints must be negligible. This article employs a “thought experiment” to demonstrate that neither of these positions can be justified by appeal to general properties of culture or of evolution. Natural selection can produce mechanisms of cultural transmission that are neither adaptive nor consistent with the predictions of acultural evolutionary models (those ignoring cultural evolution). On the other hand, natural selection can also produce mechanisms of cultural transmission that are highly consistent with acultural models. Thus, neither side of the sociobiology debate is justified in dismissing the arguments of the other. Natural selection may impose significant constraints on some human behaviors, but negligible constraints on others. Models of simultaneous genetic/cultural evolution will be useful in identifying domains in which acultural evolutionary models are, and are not, likely to be useful.

Title (up) Dominance relationships between adult Plains zebra stallions in semi – captivity Type Journal Article
Year 1988 Publication Behaviour Abbreviated Journal Behaviour
Volume 104 Issue 3-4 Pages 300-319
Keywords
Abstract The relationships between 4-5 adult zebra stallions, living in a safari park, were investigated over a period of 5 years. Asymmetries in the distributions of a number of behaviours could be explained by adopting dominance as an intervening variable. Dominance in stallions was of a bipolar nature with on the one hand behaviours representing subordinance and defence, and on the other hand behaviours reinforcing and confirming dominance. Expression of formal dominance seems to play a minor role. The dyadic relationships of stallions differed as to the number of behaviours reflecting dominance relationships. Although often linear rank-orders could be constructed, these rank-orders were not necessarily identical. This means that the concept of dominance is of only limited value for describing relationships between zebra stallions.

Title (up) Effect of meal frequency on fluid balance and behavior of ponies Type Journal Article
Year 1988 Publication Physiology & behavior Abbreviated Journal Physiol. Behav.
Volume 42 Issue 5 Pages 401-407
Keywords Animals; Behavior, Animal/*physiology; Blood Proteins/analysis; *Eating; Female; Hematocrit; Horses/blood/*physiology; Osmolar Concentration; *Water-Electrolyte Balance
Abstract Twelve ponies were fed their total daily ration either as one large meal or divided into six small meals. Pre- and post-feeding behavior was recorded six times a day. Blood samples were taken for 30 min before and two hr after the meal. Plasma protein increased from 7.0 to a peak of 7.3 g/dl with small meals and from 7.3 to 8.1 g/dl with large meals, and returned to pre-feeding levels by 90 min post-feeding. Hematocrit rose from 33.3 to 34.1% with small meals and from 33.0 to 36.0% with large meals. These rapid and short-lived increases indicate a decrease in plasma volume. Plasma osmolality rose with feeding from 283 to 285 mosmoles/kg with small meals and from 281 to 288 mosmoles/kg with large meals. Water availability had no significant effect on blood changes. Digestibility and rate of passage were measured with chromic oxide, but there were no differences. Vocalizing (neighing) and walking occurred more often before than after feeding, while eating bedding and engaging in other oral behaviors were more frequent after feeding.
