  Title The effect of tied rank numbers on the linearity of dominance hierarchies Type Journal Article
  Year 1986 Publication Behavioural Processes Abbreviated Journal Behav. Process.  
  Volume 12 Issue 2 Pages 159-168  
  Keywords dominance hierarchy, linearity, Landau's index, despotism  
  Abstract The occurence of tied rank numbers in dominance hierarchies is discussed, especially its effect on the linearity of the hierarchy. This linearity is measured with Landau's index, that is calculated for several hierarchies with tied ranks on one, two of three levels. Linearity is mostly affected by ties in small groups with many ties. A distinction is made between a hierarchy of individuals and hierarchical levels. The phenomenon of despotism is called an extreme case of tied ranks. It is proposed to regard hierarchies with a linearity in a continuous scale.

  Title Exchangeable producer and scrounger roles in a captive flock of feral pigeons: a case for the skill pool effect Type Journal Article
  Year 1986 Publication Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 34 Issue 3 Pages 797-803  
  Keywords  
  Abstract We investigated the foraging producer-scrounger system of a captive flock of feral pigeons (Columba livia) by monitoring the number of food patches each individual produced. In one experiment, three different patch types were tested on the whole flock while, in a second, flock composition was varied for one patch type. In all cases we found non-uniform distributions of the number of patches produced per individual, which suggests the existence of producer and scrounger roles. This result could not be explained by either dominance or variability in individual learning ability. Individuals switched roles in response to changes both in food patch type and flock composition. These results are discussed in light of the skill pool hypothesis, which suggests that, in a group, different foraging specialists will profit by parasitizing each other's food discoveries.

  Title Spatial relations between mares and foals of the Welsh pony (Equus caballus) Type Journal Article
  Year 1986 Publication Animal Behaviour Abbreviated Journal Anim Beh  
  Volume 34 Issue 4 Pages 1007-1015  
  Keywords  
  Abstract Welsh pony mares and foals (Equus caballus) were usually found to be within 1 or 5 m of each other during the first week of the foal's life and gradually spent more time at greater distances as the foals became older. There was an overall levelling of the trend during the 9th-15th weeks of life of the foal, followed by a second period of change during weeks 16-24. Through weeks 21-24, mares and foals spent at least half of their time within 5 m of each other. Proximity was primarily due to foal activity except during foal recumbency. During the first 8 weeks of the foal's life, a mare remained close by when it was recumbent, either by grazing in a circle around it or by standing upright beside it. Mares and foals were most likely to be close together when they were resting upright with the other ponies in the herd and most likely to be far apart when the foal was playing. Similarities in patterns of spatial relationship between the foals of a given mare were demonstrated. There was no difference between colts and filies in the development of independence.

  Title Longitudinal data analysis using generalized linear models Type Journal Article
  Year 1986 Publication Biometrika Abbreviated Journal  
  Volume 73 Issue 1 Pages 13-22  
  Keywords  
  Abstract This paper proposes an extension of generalized linear models to the analysis of longitudinal data. We introduce a class of estimating equations that give consistent estimates of the regression parameters and of their variance under mild assumptions about the time dependence. The estimating equations are derived without specifying the joint distribution of a subject's observations yet they reduce to the score equations for niultivariate Gaussian outcomes. Asymptotic theory is presented for the general class of estimators. Specific cases in which we assume independence, m-dependence and exchangeable correlation structures from each subject are discussed. Efficiency of the pioposecl estimators in two simple situations is considered. The approach is closely related to quasi-likelihood.
