  Title Evaluation of Stress During Transport Type Journal Article
  Year 2003 Publication Veterinary Research Communications Abbreviated Journal  
  Volume 27 Issue (up) Pages 519-524  
  Keywords hormones – physiological variables – stress – transport procedures  
  Abstract Domestic animals are transported for a variety of reasons including breeding, biomedical purposes, slaughter and, in the case of sporting horses, for competitions, pleasure activities or ceremonial proceedings. Studies to determine the amount of stress on farm animals during transport often have highly variable results and are difficult to interpret. The reaction of animals to stressors depends on the duration and intensity of the stressors, the animal's previous experience, its physiological status and the immediate environmental restraints. Behavioural, haematological, haematochemical, physiological and neuro-hormonal (ß-endorphin, ACTH, cortisol, iodothyronines) variables are discussed on the basis of handling, loading and transport procedures of animals.

  Title Behaviour and welfare of individual laying hens in a non-cage system Type Journal Article
  Year 2003 Publication British poultry science Abbreviated Journal Br Poult Sci  
  Volume 44 Issue (up) 1 Pages 22-29  
  Keywords *Animal Welfare; Animals; *Behavior, Animal; *Chickens; Female; Housing, Animal/*standards; Oviposition  
  Abstract 1. A leg band containing a transponder was fitted to 80 birds in a perchery containing 1,000 birds. 2. The transponder emitted a unique identification number when a bird walked on one of 8 flat antennae on the floor. The recording apparatus was used to measure the amount of time that each of the tagged birds spent on the slatted and littered areas in a 6-week period. 3. Some birds spent long periods of time on the slats, possibly as a means of avoiding repeated attacks. Duration on the slats was greatest in birds with the worst (as opposed to better) feather scores of the head, back and tail regions. 4. Birds that spent long periods on the slats were lighter than other birds at both 39 weeks of age and 72 weeks of age and had greater back, head and tail feather damage, consistent with these birds being victims of pecking. 5. Tagged birds received a social avoidance test outside the perchery at 39 weeks of age, which suggested that birds retreated to the slats in response to pecks rather than just to close proximity to other birds. 6. The failure to find that duration on the slats was related to anatomical indicators of stress (liver, spleen and bursa of Fabricius) suggests that retreating to the slats following pecking attenuates physiological stress responses. 7. We conclude that the provision of areas where birds in a large group can avoid pecking may improve the welfare of a minority of victimised birds.

  Title The mother-offspring relationship as a template in social development: reconciliation in captive brown capuchins (Cebus apella) Type Journal Article
  Year 2003 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol  
  Volume 117 Issue (up) 1 Pages 101-110  
  Keywords *Adaptation, Psychological; Animals; Behavior, Animal/*physiology; Cebus; Conflict (Psychology); Female; Male; *Maternal Behavior; Pilot Projects; *Social Behavior; Statistics, Nonparametric  
  Abstract Mother-offspring (MO) relationship quality was investigated to determine its influence on the development of reconciliation--affiliation between opponents shortly after a fight--because it influenceswhat distressed youngsters learn about calming down. Data were longitudinal and cross-sectional observational samples of 38 MO pairs of monkeys across 24 months. An MO relationship quality index (RQI) classified each pair as secure or insecure. Reconciliation emerged in infancy.Secure youngsters had an appeasing conciliatory style, and insecure youngsters had an agitated conciliatory style. Conclusions are that reconciliation develops from the attachment behavior system and MO RQI is related to the particular conciliatory style youngsters develop by affecting how aroused they are by conflict and the subsequent socializing they seek to calm down.

  Title The Evolution of Group-beneficial Traits in the Absence of Between-group Selection Type Journal Article
  Year 2003 Publication Journal of Theoretical Biology Abbreviated Journal J. Theor. Biol.  
  Volume 220 Issue (up) 1 Pages 67-74  
  Keywords  
  Abstract One specific prediction emerging from trait-group models of natural selection is that when individuals possess traits that benefit other group members, natural selection will favor “cheating” (i.e. not possessing the group-beneficial trait) within groups. Cheating is selected within groups because it allows individuals to avoid bearing the relative costs typically associated with group-beneficial traits, but to still reap the benefits associated with the acts of other group members. Selection between groups favors traits that benefit other group members. The relative strength of within- and between-group selection then determines the equilibrium frequency of those who produce group-beneficial traits and those that do not. Here we demonstrate that individual-level selection, that is selection within groups can also produce an intermediate frequency of such group-beneficial traits by frequency-dependent selection. The models we develop are general in nature, but were inspired by the evolution of antibiotic resistance in bacteria. The theory developed here is distinct from prior work that relies on reciprocity or kinship per'se to achieve cooperation and altruism among group members.

  Title Do capuchin monkeys, Cebus apella, know what conspecifics do and do not see? Type Journal Article
  Year 2003 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 65 Issue (up) 1 Pages 131-142  
  Keywords  
  Abstract Capuchin monkeys were tested in five experiments in which two individuals competed over food. When given a choice between retrieving a piece of food that was visible or hidden from the dominant, subordinate animals preferred to retrieve hidden food. This preference is consistent with the hypotheses that either (1) the subordinate knew what the dominant could and could not see or (2) the subordinate was monitoring the behaviour of the dominant and avoiding the piece of food that it approached. To test between these alternatives, we released subordinates with a slight head start forcing them to make their choice (between a piece of food hidden or visible to the dominant) before the dominant entered the area. Unlike chimpanzees, Pan troglodytes, subordinates that were given a head start did not preferentially approach hidden pieces of food first. Therefore, our experiments provide little support for the hypothesis that capuchin monkeys are sensitive to what another individual does or does not see. We compare our results with those obtained with chimpanzees in the same paradigm and discuss the evolution of primate social cognition.
