  Title Influence of an active stable system on the behavior and body condition of Icelandic horses Type Journal Article
  Year 2012 Publication (up) animal Abbreviated Journal  
  Volume 6 Issue 10 Pages 1684-1693  
  Keywords activity, automatic feeding system, behavior, body condition score, Icelandic horse  
  Abstract Horses are often stabled in individual boxes, a method that does not meet their natural needs and may cause psychical and

musculoskeletal diseases. This problem is particularly evident in Iceland, where horses often spend the long winter periods in cramped

boxes. The aim of this study was to analyze the suitability of a group housing system in Iceland, but the results are also applicable to

horses of other regions. Eight Icelandic horses were observed in an active stable system, and their behavior and time budget were

recorded. Movement and lying behavior were studied with ALT (Activity, Lying, Temperature detection) pedometers. The effect of an

automatic concentrate feeding station (CFS) on the horses’ behavior was examined. In the first period of investigation, the horses

were fed concentrates manually, and in the second period, they were fed with the CFS. Additional behavioral observations and a

determination of social hierarchy occurred directly or by video surveillance. The physical condition of the horses was recorded by body

weight (BW) measurement and body condition scoring (BCS). The results showed a significant increase between the first and second

trial periods in both the activity (P,0.001) and the lying time (P50.003) of the horses with use of the CFS. However, there was no

significant change in BW during the first period without the CFS (P50.884) or during the second period with the CFS (P50.540).

The BCS of the horses was constant at a very good level during both trial periods, and the horses showed a low level of aggression, a

firm social hierarchy and behavioral synchronization. This study concludes that group housing according to the active stable principle is

a welfare-friendly option for keeping horses and is a suitable alternative to conventional individual boxes.

  Title Repeatability and heritability of exploratory behaviour in great tits from the wild Type Journal Article
  Year 2002 Publication (up) Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 64 Issue 6 Pages 929-938  
  Keywords  
  Abstract We investigated whether individual great tits, Parus major, vary consistently in their exploratory behaviour in a novel environment and measured the repeatability and heritability of this trait. Wild birds were caught in their natural habitat, tested in the laboratory in an open field test on the following morning, then released at the capture site. We measured individual consistency of exploratory behaviour for recaptured individuals (repeatability) and estimated the heritability with parent-offspring regressions and sibling analyses. Measures of exploratory behaviour of individuals at repeated captures were consistent in both sexes and study areas (repeatabilities ranged from 0.27 to 0.48). Exploration scores did not differ between the sexes, and were unrelated to age, condition at fledging or condition during measurement. Heritability estimates were 0.22-0.41 (parent-offspring regressions) and 0.37-0.40 (sibling analyses). We conclude that (1) consistent individual variation in open field behaviour exists in individuals from the wild, and (2) this behavioural variation is heritable. This is one of the first studies showing heritable variation in a behavioural trait in animals from the wild, and poses the question of how this variation is maintained under natural conditions.

  Title Laterality in the wild: preferential hemifield use during predatory and sexual behaviour in the black-winged stilt Type Journal Article
  Year 2005 Publication (up) Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 69 Issue 5 Pages 1077-1084  
  Keywords  
  Abstract We recorded preferential use of the left and right monocular visual field in black-winged stilts, Himantopus himantopus, during predatory pecking and during courtship and mating behaviour in a naturalistic setting. The stilts had a population-level preference for using their right monocular visual field before predatory pecking; pecks that followed right-hemifield detection were more likely to be successful than pecks that followed left-hemifield detection, as evinced by the occurrence of swallowing and shaking head movements after pecking. In contrast, shaking behaviour, a component of courtship displays, and copulatory attempts by males were more likely to occur when females were seen with the left monocular visual field. Asymmetric hemifield use observed in natural conditions raises interesting issues as to the costs and benefits of population-level behavioural lateralization in wild animals.

  Title Stone tool use in wild bearded capuchin monkeys, Cebus libidinosus. Is it a strategy to overcome food scarcity? Type Journal Article
  Year 2012 Publication (up) Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 83 Issue 5 Pages 1285-1294  
  Keywords bearded capuchin; Cebus libidinosus; fallback food; necessity hypothesis; nut cracking; opportunity hypothesis; tool use  
  Abstract To determine whether tool use varied in relation to food availability in bearded capuchin monkeys, we recorded anvil and stone hammer use in two sympatric wild groups, one of which was provisioned daily, and assessed climatic variables and availability of fruits, invertebrates and palm nuts. Capuchins used tools to crack open encased fruits, mostly palm nuts, throughout the year. Significant differences between wet and dry seasons were found in rainfall, abundance of invertebrates and palm nuts, but not in fruit abundance. Catulè nuts were more abundant in the dry season. We tested the predictions of the necessity hypothesis (according to which tool use is maintained by sustenance needs during resource scarcity) and of the opportunity hypothesis (according to which tool use is maintained by repeated exposure to appropriate ecological conditions, such as preferred food resources necessitating the use of tools). Our findings support only the opportunity hypothesis. The rate of tool use was not affected by provisioning, and the monthly rate of tool use was not correlated with the availability of fruits and invertebrates. Conversely, all capuchins cracked food items other than palm nuts (e.g. cashew nuts) when available, and adult males cracked nuts more in the dry season when catulè nuts (the most common and exploited nut) are especially abundant. Hence, in our field site capuchins use tools opportunistically.

  Title Flexible spatial organization of urban foxes, Vulpes vulpes, before and during an outbreak of sarcoptic mange Type Journal Article
  Year 2000 Publication (up) Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 59 Issue 1 Pages 127-146  
  Keywords  
  Abstract The social and spatial organization of urban fox groups prior to and during an outbreak of sarcoptic mange was compared with predictions derived from the resource dispersion hypothesis (RDH). We investigated the availability of three key resources. Neither daytime rest sites nor breeding sites appeared to be limited in availability. The availability of food deliberately supplied by local householders was examined by questionnaire surveys. The daily and weekly amount of food supplied was greatly in excess of the minimum requirements of a pair of foxes, but was consistent between territories. The availability of this food source increased markedly as a result of more people feeding the foxes. In agreement with the RDH, group size prior to the outbreak of mange increased from 2.25 animals (N=4) to 6.57 animals (N=7). Before the outbreak of mange, two territories were divided. Increased scavenge availability on smaller territories may have promoted these changes. Excluding these spatial changes, territories were very stable between years. After the outbreak of mange, group size declined as a direct result of mange-induced mortality. Surviving animals increased their ranges only after neighbouring groups had died out. Ranges did not increase in size in response to a decline in food availability. Nor were the increases in range size associated with the relinquishment of parts of the existing territory. These postmange changes are contrary to the RDH. Three factors may have promoted these changes: the elimination of interstitial space, the forced dispersal of young or future division of the territory.

  Title Rhesus monkey behaviour under diverse population densities: coping with long-term crowding Type Journal Article
  Year 1997 Publication (up) Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 54 Issue 3 Pages 643-662  
  Keywords  
  Abstract A popular view is that high population density promotes behavioural pathology, particularly increased aggression. In contrast, according to a coping model, some primates have behavioural mechanisms (e.g. formal displays, reconciliation and grooming) that regulate social tensions and control the negative consequences of crowding. Seven captive rhesus monkey groups, Macaca mulattawere observed over a wide range of population densities where high-density groups were over 2000 times more crowded than low-density free-ranging groups. As density increased, male rhesus monkeys increased grooming and huddling but did not increase rates of aggression. Females increased all categories of behaviour examined (heavy aggression, mild aggression, formal bared-teeth displays, grooming and huddling), but the increases were not distributed uniformly to all classes of partners. Females increased only grooming, huddling and appeasement displays to males, increased only aggression and huddling with kin and increased all categories of behaviour to non-kin adult females. There were no differences in the percentage of aggressive conflicts reconciled across density conditions. Increased density had different effects on particular relationships. Relationships between females and males were characterized by a coping pattern in which animals modified their behaviour in ways that may decrease aggression under crowded conditions. Female relationships with kin and non-kin were characterized by increases in both aggression and friendly interactions as density increased. The different patterns of response to higher density may reflect different strategies depending on the strength and stability of relationships and the potential consequences if certain relationships are disrupted.1997The Association for the Study of Animal Behaviour

  Title Quadratic postconflict affiliation among bystanders in a hamadryas baboon group Type Journal Article
  Year 2005 Publication (up) Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 69 Issue 6 Pages 1345-1355  
  Keywords  
  Abstract The tendency in primate groups for two opponents to affiliate shortly after a fight has been described as dyadic reconciliation. The response has been shown to restore disrupted relationships and curtail ongoing aggression. Rates of self-directed behaviour (e.g. scratching) are positively correlated with anxiety in primates and the rates decline after reconciliation, indicating that the response also functions to reduce postconflict tension. Third parties not involved in an aggressive interaction are also likely to affiliate with one of the combatants subsequent to a fight. Such `triadic' interactions may also promote conflict resolution when, for instance, the relatives of a victim affiliate with their relative's aggressor. Because aggression in a group influences a bystander's behaviour with combatants, we hypothesized that aggression between two animals would also influence a bystander's behaviour with other bystanders. Such `quadratic' postconflict interactions might also function to reduce postconflict tension or occur in patterns among kin subgroups to resolve conflict. We tested for quadratic interactions in an 18-member group of captive hamadryas baboons, Papio hamadryas hamadryas. Immediately following a fight, an uninvolved bystander was randomly selected for observation and its affiliative interactions with other bystanders and its displacement activities were recorded for 3 min. Rates of behaviour during these postconflict periods were compared to rates during 3-min baseline periods not preceded by aggression. Bystanders engaged in quadratic interactions by increasing affiliation with other bystanders following aggression. Bystanders directed affiliation to nonkin bystanders that were their preferred social partners. Displacement activities of bystanders were significantly higher during postconflict intervals compared to baseline intervals, and bystander displacement activity levels before affiliative contact with other bystanders were significantly higher than after contact. Apparently, bystanders become tense or anxious after witnessing aggression and affiliate with preferred partners to reduce the arousal.

  Title Social dominance correlates and family status in wintering dark-bellied brent geese, Branta bernicla bernicla Type Journal Article
  Year 2006 Publication (up) Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 71 Issue 6 Pages 1351-1358  
  Keywords  
  Abstract In many gregarious species, including ducks and geese, being dominant provides more benefits than costs, because dominants have better access to resources essential for survival or reproduction. In geese, being in better body condition during migration towards the breeding grounds positively influences reproductive success. However, underlying proximate mechanisms linking prebreeding body condition on the wintering grounds to breeding success remain poorly understood. We investigated social dominance correlates and family status, in three consecutive winters, in a free-ranging, migrating, dark-bellied brent goose population. Families with juveniles dominated pairs, and pairs dominated singletons. Dominance rank did not increase with the number of juveniles per family. Males were dominant over females. Social dominance and reproductive status for a given winter were significantly correlated with body mass, body size and body condition during the previous winter, suggesting that body condition in winter also affects subsequent breeding success and hence also dominance. Levels of testosterone and triiodothyronine were not correlated with immediate or later dominance or reproductive status. We discuss the role of family status as a signal of social status in determining reproductive strategies.
