  Title Humoral, hormonal and behavioral correlates of feeding in ponies: the effects of meal frequency Type Journal Article
  Year 1985 Publication Journal of animal science Abbreviated Journal J. Anim Sci.  
  Volume 61 Issue 5 Pages 1103-1110  
  Keywords Animals; Behavior, Animal/physiology; Blood Glucose/*analysis; Blood Proteins/*analysis; Blood Volume; *Eating; Feeding Behavior/physiology; Female; Heart Rate; Horses/blood/*physiology; Male; Osmolar Concentration; Osmotic Pressure; Triiodothyronine/*blood  
  Abstract The effect of meal frequency on body fluid, glucose, triiodothyronine (T3), heart rate and behavior was measured in 10 ponies. A simple reversal design was used in which each pony received one meal/day (1X) for 2 wk and six meals/day (6X) for 2 wk. The total intake/day was held constant. Feeding was followed by a rise in plasma levels of glucose, T3, protein and osmolality. One large meal was followed by significantly greater changes in all of the variables than was a meal one-sixth the size. Plasma T3 rose from 41 +/- 5 (SE) ng/liter before feeding to 43 +/- 5 ng/liter following a small meal, but rose significantly higher, from 39 +/- 4 to 60 +/- 10 ng/liter, following a large meal. Glucose rose from 84 +/- 3 to 109 +/- 7 mg/dl following a small meal and rose significantly higher, from 83 +/- 3 to 154 +/- 11 mg/dl, after a large meal. Plasma protein rose from 6.55 +/- .14 to 6.62 +/- .16 g/dl following a small meal and from 6.45 +/- .14 to 6.99 +/- .11 g/dl following a large meal. Osmolality rose from 227 +/- 1 mosmol/liter before to 279 +/- 1 mosmol/liter following a small meal and significantly higher from 278 +/- 2 to 285 +/- 1 mosnol/liter following a large meal. Heart rate rose from 42 beats/min in the absence of feed to 50 beats/min when food was visible to the ponies and did not rise higher when eating began. There were no significant differences in the cardiac response to one large meal and that to a small meal.(ABSTRACT TRUNCATED AT 250 WORDS)

  Title Conformity to cultural norms of tool use in chimpanzees Type Journal Article
  Year 2005 Publication Nature Abbreviated Journal Nature  
  Volume 437 Issue 7059 Pages 737-740  
  Keywords Aging/physiology; Animals; Culture; Feeding Behavior/physiology; Female; Pan troglodytes/*physiology/*psychology; *Social Conformity; Technology; Time Factors  
  Abstract Rich circumstantial evidence suggests that the extensive behavioural diversity recorded in wild great apes reflects a complexity of cultural variation unmatched by species other than our own. However, the capacity for cultural transmission assumed by this interpretation has remained difficult to test rigorously in the field, where the scope for controlled experimentation is limited. Here we show that experimentally introduced technologies will spread within different ape communities. Unobserved by group mates, we first trained a high-ranking female from each of two groups of captive chimpanzees to adopt one of two different tool-use techniques for obtaining food from the same 'Pan-pipe' apparatus, then re-introduced each female to her respective group. All but two of 32 chimpanzees mastered the new technique under the influence of their local expert, whereas none did so in a third population lacking an expert. Most chimpanzees adopted the method seeded in their group, and these traditions continued to diverge over time. A subset of chimpanzees that discovered the alternative method nevertheless went on to match the predominant approach of their companions, showing a conformity bias that is regarded as a hallmark of human culture.

  Title What-where-when memory in pigeons Type Journal Article
  Year 2006 Publication Journal of experimental psychology. Animal behavior processes Abbreviated Journal J Exp Psychol Anim Behav Process  
  Volume 32 Issue 4 Pages 345-358  
  Keywords Animals; Behavior, Animal/physiology; Columbidae; Conditioning, Operant/physiology; Memory/*physiology; Reinforcement (Psychology); Space Perception/*physiology; Spatial Behavior/physiology; Teaching; Visual Perception/physiology  
  Abstract The authors report a novel approach to testing episodic-like memory for single events. Pigeons were trained in separate sessions to match the identity of a sample on a touch screen, to match its location, and to report on the length of the retention interval. When these 3 tasks were mixed randomly within sessions, birds were more than 80% correct on each task. However, performance on 2 different tests in succession after each sample was not consistent with an integrated memory for sample location, time, and identity. Experiment 2 tested binding of location and identity memories in 2 different ways. The results were again consistent with independent feature memories. Implications for tests of episodic-like memory are discussed.

  Title A comparative study of geometric rule learning by nutcrackers (Nucifraga columbiana), pigeons (Columba livia), and jackdaws (Corvus monedula) Type Journal Article
  Year 2002 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol  
  Volume 116 Issue 4 Pages 350-356  
  Keywords Animals; Behavior, Animal/physiology; Birds; Feeding Behavior/physiology; Learning/*physiology; *Mathematics; Random Allocation; Spatial Behavior/*physiology  
  Abstract Three avian species, a seed-caching corvid (Clark's nutcrackers; Nucifraga columbiana), a non-seed-caching corvid (jackdaws; Corvus monedula), and a non-seed-caching columbid (pigeons; Columba livia), were tested for ability to learn to find a goal halfway between 2 landmarks when distance between the landmarks varied during training. All 3 species learned, but jackdaws took much longer than either pigeons or nutcrackers. The nutcrackers searched more accurately than either pigeons or jackdaws. Both nutcrackers and pigeons showed good transfer to novel landmark arrays in which interlandmark distances were novel, but inconclusive results were obtained from jackdaws. Species differences in this spatial task appear quantitative rather than qualitative and are associated with differences in natural history rather than phylogeny.

  Title Hippocampal lesions impair memory for location but not color in passerine birds Type Journal Article
  Year 1996 Publication Behavioral neuroscience Abbreviated Journal Behav Neurosci  
  Volume 110 Issue 4 Pages 831-835  
  Keywords Animals; Appetitive Behavior/physiology; Birds/*physiology; Brain Mapping; Color Perception/*physiology; Discrimination Learning/physiology; Hippocampus/*physiology; Long-Term Potentiation/physiology; Mental Recall/*physiology; Orientation/*physiology; Species Specificity  
  Abstract The effects of hippocampal complex lesions on memory for location and color were assessed in black-capped chickadees (Parus atricapillus) and dark-eyed juncos (Junco hyemalis) in operant tests of matching to sample. Before surgery, most birds were more accurate on tests of memory for location than on tests of memory for color. Damage to the hippocampal complex caused a decline in memory for location, whereas memory for color was not affected in the same birds. This dissociation indicates that the avian hippocampus plays an important role in spatial cognition and suggests that this brain structure may play no role in working memory generally.

  Title Hippocampal volume and food-storing behavior are related in parids Type Journal Article
  Year 1995 Publication Brain, behavior and evolution Abbreviated Journal Brain Behav Evol  
  Volume 45 Issue 1 Pages 54-61  
  Keywords Animals; Appetitive Behavior/*physiology; Birds/*anatomy & histology; Brain Mapping; Evolution; Food Preferences/physiology; Hippocampus/*anatomy & histology; Mental Recall/*physiology; Orientation/*physiology; Predatory Behavior/physiology; Social Environment; Species Specificity  
  Abstract The size of the hippocampus has been previously shown to reflect species differences and sex differences in reliance on spatial memory to locate ecologically important resources, such as food and mates. Black-capped chickadees (Parus atricapillus) cached more food than did either Mexican chickadees (P. sclateri) or bridled titmice (P. wollweberi) in two tests of food storing, one conducted in an aviary and another in smaller home cages. Black-capped chickadees were also found to have a larger hippocampus, relative to the size of the telencephalon, than the other two species. Differences in the frequency of food storing behavior among the three species have probably produced differences in the use of hippocampus-dependent memory and spatial information processing to recover stored food, resulting in graded selection for size of the hippocampus.

  Title Imitation of the sequential structure of actions by chimpanzees (Pan troglodytes) Type Journal Article
  Year 1998 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol  
  Volume 112 Issue 3 Pages 270-281  
  Keywords Animals; Appetitive Behavior/physiology; *Ceremonial Behavior; Exploratory Behavior/physiology; Female; Fruit; Imitative Behavior/*physiology; Learning/*physiology; Male; Pan troglodytes/*psychology; Practice (Psychology); Problem Solving/*physiology  
  Abstract Imitation was studied experimentally by allowing chimpanzees (Pan troglodytes) to observe alternative patterns of actions for opening a specially designed “artificial fruit.” Like problematic foods primates deal with naturally, with the test fruit several defenses had to be removed to gain access to an edible core, but the sequential order and method of defense removal could be systematically varied. Each subject repeatedly observed 1 of 2 alternative techniques for removing each defense and 1 of 2 alternative sequential patterns of defense removal. Imitation of sequential organization emerged after repeated cycles of demonstration and attempts at opening the fruit. Imitation in chimpanzees may thus have some power to produce cultural convergence, counter to the supposition that individual learning processes corrupt copied actions. Imitation of sequential organization was accompanied by imitation of some aspects of the techniques that made up the sequence.

  Title Rank in a food competition test and humoral immune functions in male Brandt's voles (Lasiopodomys brandtii) Type Journal Article
  Year 2007 Publication Physiology & behavior Abbreviated Journal Physiol. Behav.  
  Volume 90 Issue 2-3 Pages 490-495  
  Keywords Animals; Antibody Formation/*physiology; Arvicolinae/immunology/*physiology; Competitive Behavior/*physiology; *Dominance-Subordination; Feeding Behavior/physiology; Hydrocortisone/blood; Male; *Social Dominance; Spleen/immunology/physiology  
  Abstract Social status can influence an animal's immune and reproductive functions, eventually leading to alterations in immunocompetence and reproductive success. Here, we report that rank assessed in a food competition test, considered as an index of social status, has significant influences on humoral immune functions in male Brandt's voles (Lasiopodomys brandtii) living in a group. Our data reveal a negative correlation of the spleen mass and serum antibody levels with social status, as well as a positive correlation of serum cortisol levels with social status. Males winning in food competition had a smaller spleen, a lower level of serum antibodies, and a higher level of serum cortisol than did their conspecific counterparts. These data indicate interactions between social status and humoral immune functions and might illustrate a trade-off between infection risks and reproductive success in male Brandt's voles.

  Title Comparative morphological study on the tongue and lingual papillae of horses (Perissodactyla) and selected ruminantia (Artiodactyla) Type Journal Article
  Year 2005 Publication Italian Journal of Anatomy and Embryology = Archivio Italiano di Anatomia ed Embriologia Abbreviated Journal Ital J Anat Embryol  
  Volume 110 Issue 2 Suppl 1 Pages 55-63  
  Keywords Animals; Artiodactyla/*anatomy & histology/physiology; Cattle; Connective Tissue/physiology/ultrastructure; Feeding Behavior/physiology; Goats/anatomy & histology/physiology; Horses/anatomy & histology/physiology; Mastication/physiology; Microscopy, Electron, Scanning; Perissodactyla/*anatomy & histology/physiology; Tongue/physiology/*ultrastructure  
  Abstract A common characteristic of horses, Rocky Mountain goats, and cattle is that they all have a well developed lingual prominence on the dorsal surface of the posterior area of the tongue. Foliate papillae were found in the horse studied but not in the goat or in cattle. The horse filiform papillae had a long and slender external form with a thin and slender CTC, while in the goat and cattle the external form consisted of a large thick main process and the CTC consisted of a bundle of numerous rod-shaped protrusions. The special papilla found on the lingual prominence resembled larger filiform-like papillae in the horses; however, in the goat and cattle it was a very thick and large tongue like papillae. The horses had two large vallate papillae, while the goat and cattle had 15 or more vallate papillae at the posterior area of the lingual prominence. This suggests that the fine structure of horse tongues may display a more primitive pattern than that present in goats and cattle.
