Title Responses to quantity: perceptual versus cognitive mechanisms in chimpanzees (Pan troglodytes) Type Journal Article
Year 1995 Publication Journal of Experimental Psychology. Animal Behavior Processes Abbreviated Journal J Exp Psychol Anim Behav Process
Volume 21 Issue 1 Pages 82-86
Keywords Animals; Behavior, Animal; Choice Behavior; Cognition/*physiology; Female; *Pan troglodytes; Perception/*physiology; Reinforcement (Psychology); Task Performance and Analysis
Abstract Two chimpanzees were trained to select among 2 different amounts of candy (1-6 items). The task was designed so that selection of either array by the active (selector) chimpanzee resulted in that array being given to the passive (observer) animal, with the remaining (nonselected) array going to the selector. Neither animal was able to select consistently the smaller array, which would reap the larger reward. Rather, both animals preferentially selected the larger array, thereby receiving the smaller number of reinforcers. When Arabic numerals were substituted for the food arrays, however, the selector animal evidenced more optimal performance, immediately selecting the smaller numeral and thus receiving the larger reward. These findings suggest that a basic predisposition to respond to the perceptual-motivational features of incentive stimuli can interfere with task performance and that this interference can be overridden when abstract symbols serve as choice stimuli.

Title Intergroup grooming relations between alpha females in a population of free-ranging rhesus macaques Type Journal Article
Year 1994 Publication Folia primatologica; international journal of primatology Abbreviated Journal Folia Primatol (Basel)
Volume 63 Issue 2 Pages 63-70
Keywords Animals; Animals, Wild; Female; *Grooming; Macaca mulatta/*psychology; Male; Population Density; *Social Behavior
Abstract Intergroup affiliation among female rhesus macaques, Macaca mulatta, was examined in the captive free-ranging colony of Morgan Island, S.C., USA. The provisioned colony has many social groups (35) and is maintained at a relatively high population density (21 animals/ha) with a relatively low adult male to female ratio (1:8.8). Focal and ad libitum samples were collected on 32 adults (3 males and 29 females) from two groups. Although infrequent, grooming was observed between adult females from different groups, and alpha females were the main participants in these interactions. Colony records indicated that none of the intergroup grooms was between females formerly from a common group. Relations between familiar neighboring groups may be maintained by a combination of both affiliative and aggressive behavior.

Title The responses of female baboons (Papio cynocephalus ursinus) to anomalous social interactions: evidence for causal reasoning? Type Journal Article
Year 1995 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 109 Issue 2 Pages 134-141
Keywords Animals; Attention; Auditory Perception; *Awareness; *Concept Formation; *Dominance-Subordination; Fear; Female; Hierarchy, Social; Papio/*psychology; *Social Behavior; Social Environment; Vocalization, Animal
Abstract Baboons' (Papio cynocephalus ursinus) understanding of cause-effect relations in the context of social interactions was examined through use of a playback experiment. Under natural conditions, dominant female baboons often grunt to more subordinate mothers when interacting with their infants. Mothers occasionally respond to these grunts by uttering submissive fear barks. Subjects were played causally inconsistent call sequences in which a lower ranking female apparently grunted to a higher ranking female, and the higher ranking female apparently responded with fear barks. As a control, subjects heard a sequence made causally consistent by the inclusion of grunts from a 3rd female that was dominant to both of the others. Subjects responded significantly more strongly to the causally inconsistent sequences, suggesting that they recognized the factors that cause 1 individual to give submissive vocalizations to another.

Title Lag screw stabilization of a cervical vertebral fracture by use of computed tomography in a horse Type Journal Article
Year 1995 Publication Journal of the American Veterinary Medical Association Abbreviated Journal J Am Vet Med Assoc
Volume 206 Issue 2 Pages 221-223
Keywords Animals; Bone Screws/*veterinary; Cervical Vertebrae/*injuries/surgery; Fracture Fixation, Internal/methods/*veterinary; Horses/*injuries/surgery; Male; Spinal Fractures/surgery/*veterinary; Tomography, X-Ray Computed/veterinary
Abstract A traumatic fracture of C2 was diagnosed radiographically in a 1-year-old German Warm-blood stallion. Fracture configuration was difficult to see on survey radiographs. Computed tomography yielded a more accurate assessment of the fracture and facilitated fracture repair with cortical lag screws. Precise screw placement, to avoid spinal cord damage, was obtained by use of computed tomography. Follow-up radiography revealed normal bone healing, and the horse was in dressage schooling 24 months after surgery.

Title Most directed forgetting in pigeons can be attributed to the absence of reinforcement on forget trials during training or to other procedural artifacts Type Journal Article
Year 1995 Publication Journal of the experimental analysis of behavior Abbreviated Journal J Exp Anal Behav
Volume 63 Issue 2 Pages 127-137
Keywords Animals; *Attention; Color Perception; Columbidae; Cues; *Discrimination Learning; *Mental Recall; Motivation; Pattern Recognition, Visual; *Reinforcement Schedule; Retention (Psychology)
Abstract In research on directed forgetting in pigeons using delayed matching procedures, remember cues, presented in the delay interval between sample and comparisons, have been followed by comparisons (i.e., a memory test), whereas forget cues have been followed by one of a number of different sample-independent events. The source of directed forgetting in delayed matching to sample in pigeons was examined in a 2 x 2 design by independently manipulating whether or not forget-cue trials in training ended with reinforcement and whether or not forget-cue trials in training included a simultaneous discrimination (involving stimuli other than those used in the matching task). Results were consistent with the hypothesis that reinforced responding following forget cues is sufficient to eliminate performance deficits on forget-cue probe trials. Only when reinforcement was omitted on forget-cue trials in training (whether a discrimination was required or not) was there a decrement in accuracy on forget-cue probe trials. When reinforcement is present, however, the pattern of responding established during and following a forget cue in training may also play a role in the directed forgetting effect. These findings support the view that much of the evidence for directed forgetting using matching procedures may result from motivational and behavioral artifacts rather than the loss of memory.

Title A wavelet-based metric for visual texture discrimination with applications in evolutionary ecology Type Journal Article
Year 1995 Publication Mathematical Biosciences Abbreviated Journal Math Biosci
Volume 126 Issue 1 Pages 21-39
Keywords Animals; Carnivora; *Ecology; Equidae; *Evolution; Humans; Mathematics; Models, Biological; Moths; *Pattern Recognition, Visual; Pigmentation
Abstract Much work on natural and sexual selection is concerned with the conspicuousness of visual patterns (textures) on animal and plant surfaces. Previous attempts by evolutionary biologists to quantify apparency of such textures have involved subjective estimates of conspicuousness or statistical analyses based on transect samples. We present a method based on wavelet analysis that avoids subjectivity and that uses more of the information in image textures than transects do. Like the human visual system for texture discrimination, and probably like that of other vertebrates, this method is based on localized analysis of orientation and frequency components of the patterns composing visual textures. As examples of the metric's utility, we present analyses of crypsis for tigers, zebras, and peppered moth morphs.

Title Intrageneric amplification of horse microsatellite markers with emphasis on the Przewalski's horse (E. przewalskii) Type Journal Article
Year 1994 Publication Animal Genetics Abbreviated Journal Anim Genet
Volume 25 Issue 6 Pages 401-405
Keywords Animals; DNA, Satellite/*genetics; *Gene Amplification; Gene Frequency; *Genetic Markers; Heterozygote; Horses/*genetics; Species Specificity
Abstract Primer sequences flanking 13 microsatellite loci isolated from the domestic horse (E. caballus) were successfully used to amplify homologous loci in the Przewalski's horse (E. przewalskii). The results demonstrate that the level of polymorphism at all 13 loci in the Przewalski's horse was comparable to that in the domestic horse and the overall exclusion probability in the Przewalski's horse was calculated to be 0.9994. The results suggest that it should be possible to use E. caballus-derived microsatellite markers to provide parentage verification and additional valuable information to the captive management of E. przewalskii. The ability to amplify corresponding loci in the remaining five species of the genus was also confirmed, illustrating the general application of markers isolated from the domestic horse to the evaluation of polymorphism in the other six species of the genus.

Title Animal behavior as a subject for veterinary students Type Journal Article
Year 1976 Publication The Cornell veterinarian Abbreviated Journal Cornell Vet
Volume 66 Issue 1 Pages 73-81
Keywords Aggression; Animals; *Behavior, Animal; Cats; Chickens; Dogs; Education, Veterinary; Goats; Horses; Humans; Maternal Behavior; Mice; New York; Sexual Behavior, Animal; Sheep; Sleep; Social Behavior; Social Dominance; Swine
Abstract Knowledge of animal behavior is an important asset for the veterinarian; therefore a course in veterinary animal behavior is offered at the New York State College of Veterinary Medicine as an elective. The course emphasizes the behavior of those species of most interest to the practicing veterinarian: cats, dogs, horses, cows, pigs and sheep. Dominance heirarchies, animal communication, aggressive behavior, sexual behavior and maternal behavior are discussed. Play, learning, diurnal cycles of activity and sleep, and controls of ingestive behavior are also considered. Exotic and zoo animal behaviors are also presented by experts in these fields. The critical periods of canine development are related to the optimum management of puppies. The behavior of feral dogs and horses is described. The role of the veterinarian in preventing cruelty to animals and recognition of pain in animals is emphasized. Whenever possible behavior is observed in the laboratory or on film.

Title Mitochondrial DNA sequences of various species of the genus Equus with special reference to the phylogenetic relationship between Przewalskii's wild horse and domestic horse Type Journal Article
Year 1995 Publication Journal of Molecular Evolution Abbreviated Journal J Mol Evol
Volume 41 Issue 2 Pages 180-188
Keywords Animals; Base Sequence; Chromosomes; Conserved Sequence/genetics; DNA, Mitochondrial/*genetics; Evolution; Genetic Variation/*genetics; Horses/*genetics; Molecular Sequence Data; *Phylogeny; RNA, Transfer, Pro/genetics; Sequence Alignment; Sequence Analysis, DNA
Abstract The noncoding region between tRNAPro and the large conserved sequence block is the most variable region in the mammalian mitochondrial DNA D-loop region. This variable region (ca. 270 bp) of four species of Equus, including Mongolian and Japanese native domestic horses as well as Przewalskii's (or Mongolian) wild horse, were sequenced. These data were compared with our recently published Thoroughbred horse mitochondrial DNA sequences. The evolutionary rate of this region among the four species of Equus was estimated to be 2-4 x 10(-8) per site per year. Phylogenetic trees of Equus species demonstrate that Przewalskii's wild horse is within the genetic variation among the domestic horse. This suggests that the chromosome number change (probably increase) of the Przewalskii's wild horse occurred rather recently.
