  Title (up) A Review of Wolf Predation in Southern Europe: Does the Wolf Prefer Wild Prey to Livestock? Type Journal Article
  Year 1996 Publication Journal of Applled Ecology Abbreviated Journal J. Appl. Ecol  
  Volume 33 Issue Pages 1561-1571  
  Keywords Canis lupus, conservation, food habits, prey abundance, prey availability.  
  Abstract 1. The recent recovery of the wolf in southern Europe has not yet removed the risk

of local extinction. Wolf populations are fragmented and often comprise fewer than

500 individuals. In North America, northern and eastern Europe, wolves feed maiiily

on wild herbivores. In southern Europe, this canid has apparently adapted to feed

also on fruit, rubbish, livestock, small and medium-size mammals.

2. The main conservation problem lies with predation o n domestic ~ingulates,w liich

leads to extensive killing of wolves. The reintroduction of wild large herbivores has

been advocated as a means of reducing attacks on livestock, but predatiori on the

latter may remain high if domestic ungulates are locally abundant.

3. Our synthesis of 15 studies, published in the last 15 years, on food habits of the

wolf in southern Europe, has shown that ungulates have been the main diet component

overall. A significant inverse correlation was found between the occurrence (%) of

wild and domestic ungulates in the diet. The presence of relatively few wild ungulate

species was necessary to reduce predation on livestock.

4. Selection of wild and domestic ungulate prey was influenced mainly by their local

abundance, but also by their accessibility. Feeding dependence on rubbish was local

and rare. In Italy, the consumption of riibbish/fruit and that of ungulates was significantly

negatively correlated. Diet breadth increased as the presence of large prey

in tlie diet decreased.

5. The simultaneous reintroduction of severa1 wild ungulate species is likely to reduce

predation on livestock and may prove to be one of the most effective conservation

measures.

  Title (up) Action recognition in the premotor cortex Type Journal Article
  Year 1996 Publication Brain Abbreviated Journal  
  Volume 119 Issue 2 Pages 593-609  
  Keywords action encoding; visual responses; premotor cortex; macaque monkey  
  Abstract We recorded electrical activity from 532 neurons in the rostral part of inferior area 6 (area F5) of two macaque monkeys. Previous data had shown that neurons of this area discharge during goal-directed hand and mouth movements. We describe here the properties of a newly discovered set of F5 neurons ( mirror neurons', n = 92) all of which became active both when the monkey performed a given action and when it observed a similar action performed by the experimenter. Mirror neurons, in order to be visually triggered, required an interaction between the agent of the action and the object of it. The sight of the agent alone or of the object alone (three-dimensional objects, food) were ineffective. Hand and the mouth were by far the most effective agents. The actions most represented among those activating mirror neurons were grasping, manipulating and placing. In most mirror neurons (92%) there was a clear relation between the visual action they responded to and the motor response they coded. In [~]30% of mirror neurons the congruence was very strict and the effective observed and executed actions corresponded both in terms of general action (e.g. grasping) and in terms of the way in which that action was executed (e.g. precision grip). We conclude by proposing that mirror neurons form a system for matching observation and execution of motor actions. We discuss the possible role of this system in action recognition and, given the proposed homology between F5 and human Brocca's region, we posit that a matching system, similar to that of mirror neurons exists in humans and could be involved in recognition of actions as well as phonetic gestures.

  Title (up) Behavioral retardation in a macaque with autosomal trisomy and aging mother Type Journal Article

  Abstract The social development of a female rhesus monkey (Macaca mulatta) was followed from the day of birth until her death, at age 32 months. The subject, born to an older mother, had an extra autosome (karyotype: 43, XX, +18), an affliction that came about spontaneously. MRI scans revealed that she was also hydrocephalic. Compared to 23 female monkeys growing up under identical conditions, the subject showed serious motor deficiencies, a dramatic delay in the development of social behavior, poorly established dominance relationships, and greater than usual dependency on mother and kin. The subject was well-integrated into the social group, however.

  Title (up) Behavioural observations of reintroduced Takhi or Przewalski horses (Equus ferus przewalskii) in Mongolia Type Journal Article
  Year 1996 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 50 Issue 2 Pages 95-114  
  Keywords Horse; Przewalski's horse; Reintroduction; Time budget; Social organisation; Basic reference dataset  
  Abstract During 1992 and 1993, 14 reintroduced Przewalski Horses or Takhi (Equus ferus przewalskii) were studied in the Hustain Nuruu Mountain Steppe reserve in Mongolia. Most of the individuals did not know each other before reintroduction. These Takhi were the first of five groups due to be released in the reserve after an acclimatisation period of at least 1 year. During acclimatisation the Takhi, lived visually and acoustically separately, in fenced enclosures of approximately 45 ha each. The observations, mostly scan-sampling, were carried out in each season. The observation bouts were divided over six periods and over two harem herds. Two of the periods were in the same consecutive seasons, so comparison over the years was possible. Social integration within the Takhi herds was very high from the beginning, as described by the spatial relation and synchronisation data. Between 50 and 89% of the observation time, the behaviour of all herd members was synchronised. The amount of time spent grazing by the Takhi (30-68% of the daylight period) was similar to that of feral horses and Takhi in captivity and semi-reserves. The Takhi tended to rest in the morning and have a bimodal period of grazing at dawn and in the afternoon. The Takhi displayed clear habitat preferences for certain activities. They had a strong preference to rest at the highest point in their enclosure. They fed preferably on two or three different vegetation types (with five types available in each enclosure). The amount of time spent grazing during the non-growing seasons (49 +/- 15%) indicates that the feeding value and availability of food were sufficient. Health changes were detected adequately using condition scoring sheets. No supplementary food or water was supplied during the harsh winters. Moreover, low mortality rates and high reproductive success show that the mountain steppe is a habitat which is potentially suitable for establishing a healthy Takhi population. Takhi is the first species to return to its native habitat after living only in zoos for so many generations.

  Title (up) Bullying as a group process: Participant roles and their relations to social status within the group Type Journal Article
  Year 1996 Publication Aggressive Behavior Abbreviated Journal Aggr. Behav.  
  Volume 22 Issue 1 Pages 1-15  
  Keywords aggressive behavior; peer relations; roles; social acceptance; social groups; victimization  
  Abstract Bullying was investigated as a group process, a social phenomenon taking place in a school setting among 573 Finnish sixth-grade children (286 girls, 287 boys) aged 12–13 years. Different Participant Roles taken by individual children in the bullying process were examined and related to a) self-estimated behavior in bullying situations, b) social acceptance and social rejection, and c) belongingness to one of the five sociometric status groups (popular, rejected, neglected, controversial, and average). The Participant Roles assigned to the subject were Victim, Bully, Reinforcer of the bully, Assistant of the bully, Defender of the victim, and Outsider. There were significant sex differences in the distribution of Participant Roles. Boys were more frequently in the roles of Bully, Reinforcer and Assistant, while the most frequent roles of the girls were those of Defender and Outsider. The subjects were moderately well aware of their Participant Roles, although they underestimated their participation in active bullying behavior and emphasized that they acted as Defenders and Outsiders. The sociometric status of the children was found to be connected to their Participant Roles. © 1996 Wiley-Liss, Inc.
