	Title	A matrix partial correlation test used in investigations of reciprocity and other social interaction patterns at group level			Type	Journal Article
	Year	1990	Publication	Journal of theoretical biology	Abbreviated Journal	J. Theor. Biol.
	Volume	143	Issue	3	Pages	405-420
	Keywords
	Abstract	Reciprocity and other social interaction patterns can be studied at two levels, within pairs (i.e. dyadic level) and among pairs (i.e. at group level). In this paper advantages of the latter approach are emphasized. However, an analysis at group level implies the correlation of interaction matrices and because such data are statistically dependent, the significance of a correlation has to be calculated in a special way

	Title	Models of, and tests for, reciprocity, unidirectionality and other social interaction patterns at a group level			Type	Journal Article
	Year	1990	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	39	Issue	6	Pages	1013-1029
	Keywords
	Abstract	Research on reciprocity is impaired by confusing definitions and often wrongly used statistical tests. Here, two models of the mechanism on which reciprocity may be based are discussed and an initial step towards a new fremework for its analysis is presented. A distinction is made between reciprocity and interchange. In the case of reciprocity, for one kind of act the same kind is received in return. In interchange, however, two different kinds of acts are bartered. Three types of reciprocity/interchange in social actions among all pairs of group-members are distinguished ([`]qualitative', [`]relative' and [`]absolute') on the basis of the precision of the reciprocity/interchange. Permutation procedures for association between matrices (such as the Mantel Z and two other newly derived tests) are used as a statistical test for detecting reciprocity/interchange. A rough comparison of the power of the two new tests is included. The tests can be applied to all kinds of group-living animals and to all sorts of social behaviour. The distinction between the three types of reciprocity/interchange and the matching statistical methods are also useful for defining and detecting other patterns in social interactions, like unidirectionality and associations between different kinds of social behaviour. The influence on social interactions of variables like dominance rank, age and sex can be analysed in the three forms by testing correlations between invented matrices which represent the influence of these variables (the so-called hypothesis matrices) and social interaction matrices. These methods are extended for two categories of individuals, thus allowing the investigation of, for example, reciprocity between males and females. The methods are illustrated with examples of coalition formation and grooming behaviour among captive chimpanzees, Pan troglodytes.

	Title	Social networks with two sets of actors			Type	Journal Article
	Year	1990	Publication	Psychometrika	Abbreviated Journal	Psychometrika
	Volume	55	Issue	4	Pages	707-720
	Keywords
	Abstract	Abstract Traditional network research analyzes relational ties within a single group of actors: the models presented in this paper involve relational ties exist beteen two distinct sets of actors. Statistical models for traditional networks in which relations are measured within a group simplify when modeling unidirectional relations measured between groups. The traditional paradigm results in a one-mode socionatrix; the network paradigm considered in this paper results in a two-mode socionatrix; A statistical model is presented, illustrated on a sample data set, and compared to its traditional counterpart. Extensions are discussed, including those that model multivariate relations simultaneously, and those that allow for the inclustion of attributes of the individuals in the group.

	Title	Neocortical development and social structure in primates			Type	Journal Article
	Year	1990	Publication	Primates	Abbreviated Journal	Primates
	Volume	31	Issue	2	Pages	283-289
	Keywords	Neocortex – Relative size – Allometry – Congeneric group – Social structure – Monogyny – Polygyny – Primates
	Abstract	AbstractÂ Â The relationships between the relative size of the neocortex and differences in social structures were examined in prosimians and anthropoids. The relative size of the neocortex (RSN) of a given congeneric group in each superfamily of primates was measured based on the allometric relationships between neocortical volume and brain weight for each superfamily, to control phylogenetic affinity and the effects of brain size. In prosimians, â€œtroop-makingâ€ congeneric groups (N=3) revealed a significantly larger RSN than solitary groups (N=6), and there was a significant, positive correlation between RSN and troop size. In the case of anthropoids, polygynous/frugivorous groups (N=5) revealed a significantly larger RSN than monogynous/frugivorous groups (N=8). Furthermore, a significant, positive correlation between RSN and troop size was found for frugivorous congeneric groups of the Ceboidea. These results suggest that neocortical development is associated with differences in social structure among primates.

	Title	Feeding competition between grazing red deer hinds			Type	Journal Article
	Year	1990	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	40	Issue	1	Pages	105-111
	Keywords
	Abstract	The effect of social rank on the feeding behaviour of female red deer, Cervus elaphus L., on the Isle of Rhum, Scotland, was investigated. Hinds were less likely to approach and more likely to leave the vicinity of other individuals if these hinds were dominant to them. Movements away by subordinates were more likely to involve a break from feeding. Feeding rate, as measured by bite rate, increased with distance from dominant neighbours, but was unaffected by the distance to subordinates. It appears that aggressive interactions had little direct effect on access to food. Instead, it is suggested that feeding competition in red deer hinds is largely a passive process, operating through the avoidance of conflict by subordinates.

	Title	The effects of avian mobbing on a potential predator, the European kestrel, Falco tinnunculus			Type	Journal Article
	Year	1990	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	39	Issue	5	Pages	821-827
	Keywords
	Abstract	European kestrels were observed being mobbed by other birds on 63 occasions. Eleven species were involved, and in two instances mobs were composed of more than one species. Both flight-hunting and perch-hunting kestrels flew significantly further between their foraging positions when they were mobbed than when they were not mobbed; on average, mobbing resulted in flight-hunting kestrels moving 6[middle dot]8 times, and perch-hunting kestrels 2[middle dot]7 times, the mean distances moved by non-mobbed birds. The mean strike distance of perch-hunting kestrels attempting to capture birds was significantly less than the distance between perches flown by perch-hunting kestrels when mobbed. These data provide quantitative support for the assumption that mobbing causes a predator to vacate its immediate foraging area. The activity of the kestrels also influenced the frequency that they were mobbed, with kestrels that were flight-hunting being mobbed more than expected compared with ones that were perch-hunting. Kestrels were observed being mobbed throughout the year, and there was no discernible difference in their response to mobbing between seasons. These results are discussed in relation to current ideas on the functions of avian mobbing.
