  Title (down) What do rats learn about the geometry of object arrays? Tests with exploratory behavior Type Journal Article
  Year 2005 Publication Journal of experimental psychology. Animal behavior processes Abbreviated Journal J Exp Psychol Anim Behav Process  
  Volume 31 Issue 2 Pages 142-154  
  Keywords Animals; Behavior, Animal; *Discrimination Learning; *Exploratory Behavior; Female; *Form Perception; Habituation, Psychophysiologic; Male; Rats; Rats, Long-Evans  
  Abstract Six experiments using habituation of exploratory behavior tested whether disoriented rats foraging in a large arena encode the shapes of arrays of objects. Rats did not respond to changes in position of a single object, but they responded to a change in object color and to a change in position of 1 object in a square array, as in previous research (e.g., C. Thinus-Blanc et al., 1987). Rats also responded to an expansion of a square array, suggesting that they encoded sets of interobject distances rather than overall shape. In Experiments 4-6, rats did not respond to changes in sense of a triangular array that maintained interobject distances and angles. Shapes of object arrays are encoded differently from shapes of enclosures.

  Title (down) Watching the best nutcrackers: what capuchin monkeys (Cebus apella) know about others' tool-using skills Type Journal Article
  Year 2005 Publication Animal cognition Abbreviated Journal Anim. Cogn.  
  Volume 8 Issue 4 Pages 215-219  
  Keywords Animals; *Association Learning; Cebus/*psychology; *Feeding Behavior; Female; Male; Nuts; *Problem Solving  
  Abstract The present work is part of a decade-long study on the spontaneous use of stones for cracking hard-shelled nuts by a semi-free-ranging group of brown capuchin monkeys (Cebus apella). Nutcracking events are frequently watched by other individuals--usually younger, less proficient, and that are well tolerated to the point of some scrounging being allowed by the nutcracker. Here we report findings showing that the choice of observational targets is an active, non-random process, and that observers seem to have some understanding of the relative proficiency of their group mates, preferentially watching the more skilled nutcrackers, which enhances not only scrounging payoffs, but also social learning opportunities.

  Title (down) Watching fights does not alter a bystander's response towards naive conspecifics in male green swordtail fish, Xiphophorus helleri Type Journal Article
  Year 2005 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 69 Issue 5 Pages 1139-1145  
  Keywords  
  Abstract Bystanders are capable of extracting cues from signalling interactions between others and appear to use information gained via eavesdropping when confronted with the watched individuals. A question that has gained little attention is whether observing fights affects bystander behaviour outside the context of interacting with the watched individuals. Our aim was to determine whether watching fights elicits general changes in bystander aggression levels in Xiphophorus helleri. We manipulated the bystanders' ability to witness encounters using clear, one-way-mirror and opaque partitions. After watching (or not watching) an initial contest, the bystanders were pitted against naive conspecifics instead of the animals they had seen fight. Observing fights did not alter the bystanders' propensity to initiate aggression, escalate, or win against naive individuals, indicating that bystanders do not experience general changes in aggressive behaviour after watching a fight. Earlier work in this species, however, has shown that bystanders respond in predictable ways to individuals they have witnessed winning or losing a fight. Taken together, these data support the notion that bystanders consistently modify their behaviour towards previously watched winners or losers in response to information gained via eavesdropping. We discuss our results in light of some recent work on the behavioural and endocrinological responses triggered by watching fights and suggest that comparative approaches to understanding networking phenomena may be productive.

  Title (down) Variable specificity in the anti-predator vocalizations and behaviour of the white-faced capuchin, Cebus capucinus Type Journal Article

  Abstract (Accepted: 23 June 2005)

Summary

Much research in animal communication is aimed at understanding the functional design

features of animal vocal signals. Our detailed analyses of the vocalizations and behavioural

responses elicited in white-faced capuchins by predators and other disturbances point to two

call variants that differ modestly in their acoustic structure and that are accompanied by

functionally distinct behavioural responses. The first variant is given exclusively to avian

predators and is almost invariably accompanied by the monkeys immediate descent from

the treetops where it is most vulnerable; therefore, we label this call variant the aerial

predator alarm?. The second variant, that differs only slightly but noticeably from the first,

is given to a wide range of snakes and mammals, including a range of species that represent

no predatory threat to the monkeys. This second call is also associated with more variable

responses from calling monkeys, from delayed retreat from the source of disturbance, to

active approach, inspection, and sometimes mobbing of the animal involved. We therefore

label this variant more generally as an “alerting call”. Although some other primate species

show a more diverse system of anti-predator calls, and the capuchins themselves may yet

be found to produce a greater variety of calls, a system of two call variants with varying

degrees of predator specificity and behavioural response is not uncommon among primates

and appears functionally appropriate for capuchins. The basic structure of the alerting call

allows conspecific listeners to localize the caller and the source of disturbance readily, thereby

allowing listeners to approach and assist in mobbing in cases where the disturbance warrants

it, or to avoid the area in cases where the disturbance is identified as a predatory threat.

Conversely, the aerial predator alarm is inherently less localizable and therefore conveys the

  Title (down) Use of a Bayesian risk-mapping technique to estimate spatial risks for mare reproductive loss syndrome in Kentucky Type Journal Article
  Year 2005 Publication American Journal of Veterinary Research Abbreviated Journal Am J Vet Res  
  Volume 66 Issue 1 Pages 17-20

  Abstract OBJECTIVE: To estimate spatial risks associated with mare reproductive loss syndrome (MRLS) during 2001 among horses in a specific study population and partition the herd effects into those attributable to herd location and those that were spatially random and likely attributable to herd management. Animals-Pregnant broodmares from 62 farms in 7 counties in central Kentucky. PROCEDURE: Veterinarians provided the 2001 abortion incidence proportions for each farm included in the study. Farms were georeferenced and data were analyzed by use of a fully Bayesian risk-mapping technique. RESULTS: Large farm-to-farm variation in MRLS incidence proportions was identified. The farm-to-farm variation was largely attributed to spatial location rather than to spatially random herd effects. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicate that there are considerable data to support an ecologic cause and potential ecologic risk factors for MRLS. Veterinary practitioners with more detailed knowledge of the ecology in the 7 counties in Kentucky that were investigated may provide additional data that would assist in the deduction of the causal factor of MRLS via informal geographic information systems analyses and suggest factors for inclusion in further investigations.

  Title (down) Untersuchungen zum Einfluss der Fütterung auf den Säure-Basen-Haushalt bei Ponys Type Manuscript
  Year 2005 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords  
  Abstract In der praktischen Pferdefütterung kommen regelmäßig Substanzen zum Einsatz, die

einen erheblichen Einfluss auf den Säure-Basen-Haushalt ausüben. Andererseits können

Manipulationen des Säure-Basen-Haushaltes in der Diätetik erwünscht sein, z.B. bei

Harnsteinen oder hyperkaliämischer periodischer Paralyse. Verschiebungen im Säure-

Basen-Gleichgewicht treten – unabhängig von der Fütterung – außerdem bei starker

körperlicher Aktivität auf, eine eventuelle Prophylaxe durch die Ernährung wird

ebenfalls diskutiert. Der Einfluss der Fütterung auf den Säure-Basen-Haushalt ist beim

Pferd bisher nur wenig und nicht systematisch untersucht, während sich viele Arbeiten

mit dem Effekt körperlicher Belastung beschäftigen. Analogieschlüsse zu anderen

Spezies müssen äußerst vorsichtig betrachtet werden, da die Absorption von am Säure-

Basen-Haushalt beteiligten Substanzen beim Pferd Unterschiede zu anderen Spezies

aufweist (Meyer, 1982).

In der vorliegenden Untersuchung sollte daher der Effekt von verschiedenen Chloriden

(Natriumchlorid, Kalziumchlorid, Ammoniumchlorid) auf den Säure-Basen-Haushalt bei

Ponys geprüft werden. In den ersten Versuchsdurchgängen wurden für Kleinpferde im

Erhaltungsstoffwechsel für diesen Zweck Rationen mit sehr hohen Heuanteilen

verwendet. Trotz hoher Dosen des bei verschiedenen Spezies stark säuernden

Ammoniumchlorids traten bei den Ponys nur relativ kleine Effekte auf. Bei der weiteren

Durchsicht des Schrifttums fiel auf, dass Einzelbeobachtungen zu stark säuernden

Effekten nur bei Rationen mit hohem Anteil an Kraftfutter und geringem Anteil an

Rauhfutter auftraten. Daher wurde der Effekt von Ammoniumchlorid auf einer stark

kraftfutterhaltigen Ration nochmals überprüft.
