  Title Wild Horses of the Great Basin: Social Competition and Population Size Type Book Whole
  Year 1986 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords (down) Wildlife Behavior Ecology  
  Abstract Editorial Reviews

From Library Journal

Berger begins this scholarly and absorbing treatise by discussing the natural history of the horse in general. Then, on the basis of several years of field work, he describes and details the behavior and ecology of the wild horses in the Great Basin Desert of Nevada. The purpose of the book is not, however, merely to describe natural history, but also to test quantitatively several basic ecological hypotheses. Berger has done both well, and his book will be a major source of information on North American wild horses for years to come. The book will interest specialists and graduate students primarily. It may also appeal to anyone with a strong interest in wild horses, and the remote and starkly beautiful Great Basin. Nicholas J. Volkman, Point Reyes Bird Observatory, Stinson Beach, Cal.

  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 (down) 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 Social rank, dominance, antler size, and access to food in snow-bound wild woodland caribou Type Journal Article
  Year 1986 Publication Behaviour Abbreviated Journal Behaviour  
  Volume 97 Issue 1-2 Pages 118-146  
  Keywords (down) Canada; Quebec; Artiodactyla; Social dominance; Feeding behavior; Morphology; Antler; Rangifer tarandus; North America; America; Ungulata; Mammalia; Vertebrata  
  Abstract We spent two winters studying the social behaviour of wild woodland caribou (Rangifer tarandus caribou) at a time when their main food (ground lichens; Cladina sp.) is available only at snow craters dug by the animals. The competition for access to such craters was severe, the animals constantly trying to take over the craters of others. During a two-month period when a group maintained a constant size (20) and composition (all age-sex classes represented), we could rank the animals in a rather linear dominance hierarchy (Landau's index = 0.87). Rank was correlated with access to resources, percent of time spent active, and percent of time feeding in craters. It was also correlated with age and antler size. However, rank is not an attribute of individuals, but of a relationship between individuals. As such it is only an intervening variable between physical attributes and access to resources, a variable whose value has meaning only within a given group. Among the three attributes studied (age, sex, antler size), the latter was by far the best predictor of the occurrence and outcome of interactions. Between two individuals within any of the three age-sex classes studied (adult and yearling males and adult females), the one with larger antlers initiated significantly more often, escalated its aggression (to the point of hitting the target) less often, and enjoyed a higher success rate in obtaining resources. When their antlers were larger than those of an adult male target (i.e. males that had shed their antlers), adult females won almost all their interactions with adult males even though they escalated only one fourth of them. This clarifies the long-standing speculation that female caribou have antlers and shed them later than males, in order to overcome their sexual handicap in competition for food in the winter. We conclude that the link between rank and dominance of an individual on one hand, and some of its attributes on the other (e.g. sex, age, weight, antler size) is fundamentally realized by the animal itself through its active preference for targets it is likely to beat, i.e. targets with smaller antlers.

  Title The integration of dominance and social bonding in primates Type Journal Article
  Year 1986 Publication The Quarterly review of biology Abbreviated Journal Q Rev Biol  
  Volume 61 Issue 4 Pages 459-479  
  Keywords (down) Animals; Female; Humans; Male; *Object Attachment; *Primates; *Social Dominance  
  Abstract Social dominance is usually viewed from the perspective of intragroup competition over access to limited resources. The present paper, while not denying the importance of such competition, discusses the dominance concept among monkeys and apes in the context of affiliative bonding, social tolerance, and the reconciliation of aggressive conflicts. Two basic proximate mechanisms are supposed to provide a link between dominance and interindividual affiliation, namely, formalization of the dominance relationship (i.e., unequivocal communication of status), and conditional reassurance (i.e., the linkage of friendly coexistence to formalization of the relationship). Ritualized submission is imposed upon losers of dominance struggles by winners; losers are offered a “choice” between continued hostility or a tolerant relationship with a clearly signalled difference in status. If these two social mechanisms are lacking, aggression is bound to have dispersive effects. In their presence, aggression becomes a well-integrated, even constructive component of social life. In some higher primates this process of integration has reached the stage where status differences are strongly attenuated. In these species, sharing and trading can take the place of overt competition. The views underlying this “reconciled hierarchy” model are only partly new, as is evident from a review of the ethological literature. Many points are illustrated with data on a large semi-captive colony of chimpanzees (Pan troglodytes), particularly data related to striving for status, reconciliation behavior, and general association patterns. These observations demonstrate that relationships among adult male chimpanzees cannot be described in terms of a dichotomy between affiliative and antagonistic tendencies. Male bonding in this species has not been achieved by an elimination of aggression, but by a set of powerful buffering mechanisms that mitigate its effects. Although female chimpanzees do exhibit a potential for bonding under noncompetitive conditions, they appear to lack the buffering mechanisms of the males.

  Title Strongylid parasites of horses: experimental ecology of the free-living stages on the Canadian prairie Type Journal Article
  Year 1986 Publication American Journal of Veterinary Research Abbreviated Journal Am J Vet Res  
  Volume 47 Issue 8 Pages 1686-1693  
  Keywords (down) Animals; Canada; Ecology; Feces; Female; Horse Diseases/*epidemiology/parasitology; Horses; Larva; Ovum/cytology; Seasons; Strongyloides/isolation & purification; Strongyloidiasis/epidemiology/*veterinary  
  Abstract Each month for a 1-year period (October through September), equine fecal masses containing eggs of strongylid nematodes were placed outdoors on small grass plots in Saskatchewan, Canada. Thereafter, feces and grass from the plots were sampled after intervals of 1 week or longer, and the strongylid eggs and larvae recovered were counted. These observations were made over a 2-year period. Development of eggs to infective larvae occurred in all experiments, except those established in October, December, and January. Infective larvae from experiments set up in April through September survived that winter. During the summer, there was a gradual build up of infective larvae in the fecal masses, which reached a peak in August and September and then decreased into the winter. These results are discussed in the context of the control of strongylid parasites of horses on the Canadian prairie and in other areas of the world with a similar climate and similar horse management practices.

  Title Localization of tones by horses: use of binaural cues and the role of the superior olivary complex Type Journal Article
  Year 1986 Publication Behavioral Neuroscience Abbreviated Journal Behav Neurosci  
  Volume 100 Issue 1 Pages 93-103  
  Keywords (down) Animals; Auditory Pathways/physiology; Auditory Perception/*physiology; Avoidance Learning/physiology; Brain Mapping; Electroshock; Female; Horses/*physiology; Male; Olivary Nucleus/anatomy & histology/*physiology; Orientation/physiology; Pitch Perception/physiology; Sound Localization/*physiology  
  Abstract The ability of horses to use binaural time and intensity difference cues to localize sound was assessed in free-field localization tests by using pure tones. The animals were required to discriminate the locus of a single tone pip ranging in frequency from 250 Hz to 25 kHz emitted by loudspeakers located 30 degrees to the left and right of the animals' midline (60 degrees total separation). Three animals were tested with a two-choice procedure; 2 additional animals were tested with a conditioned avoidance procedure. All 5 animals were able to localize 250 Hz, 500 Hz, and 1 kHz but were completely unable to localize 2 kHz and above. Because the frequency of ambiguity for the binaural phase cue delta phi for horses in this test was calculated to be 1.5 kHz, these results indicate that horses can use binaural time differences in the form of delta phi but are unable to use binaural intensity differences. This finding was supported by an unconditioned orientation test involving 4 additional horses, which showed that horses correctly orient to a 500-Hz tone pip but not to an 8-kHz tone pip. Analysis of the superior olivary complex, the brain stem nucleus at which binaural interactions first take place, reveals that the lateral superior olive (LSO) is relatively small in the horse and lacks the laminar arrangement of bipolar cells characteristic of the LSO of most mammals that can use binaural delta I.
