	Title	Variation in conformation of Swedish warmblood horses and conformational characteristics of elite sport horses			Type	Journal Article
	Year	1990	Publication	Equine Veterinary Journal	Abbreviated Journal	Equine Vet J
	Volume	22	Issue	3	Pages	186-193
	Keywords	Age Factors; Analysis of Variance; Animals; Breeding; Female; Forelimb/anatomy & histology; Hindlimb/anatomy & histology; Horses/anatomy & histology/physiology; Least-Squares Analysis; Male; Physical Conditioning, Animal; Regression Analysis; Sex Characteristics
	Abstract	The variation in conformation of 356 Swedish Warmblood horses is described, using a quantitative method of measuring horses. Thirty-three of the horses were elite dressage horses, 28 were elite showjumpers, 100 were riding school horses and 195 were unselected four-year-olds. Most horses had a long body form. The average height at the withers was 163.4 cm. Sixty per cent of the horses had a bench knee conformation, 50 per cent had a toe-in conformation of the forelimbs and 80 per cent had outwardly rotated hind limbs. The majority of these deviations were mild or moderate. Conformation was influenced by sex and age. Mares were smaller and had longer bodies and shorter limbs. The elite dressage horses and showjumpers had larger hock angles and more sloping scapulas than other horses. The showjumpers also had smaller fetlock angles in the front limbs. It is suggested that the larger hock angles among the elite horses may be because hocks with small angles are more prone to injury, and because small hock angles may negatively influence the ability to attain the degree of collection necessary for good performance in advanced classes.

	Title	Urinary steroid evaluations to monitor ovarian function in exotic ungulates			Type	Journal Article
	Year	1990	Publication	Zoo Biology	Abbreviated Journal	Zoo Biol
	Volume	9	Issue	5	Pages	341 - 348
	Keywords	Perissodactyla – ovulation – corpus luteum
	Abstract	A direct enzyme immunoassay (EIA) for non-specific urinary progesterone (Po) metabolites, utilizing a non-specific monoclonal antibody against pregnanediol-3-glucuronide, was evaluated for the purpose of assessing luteal function in equids. Urinary pregnanediol-3-glucuronide (PdG) and immunoreactive PdG-like conjugate (iPdG) concentrations, indexed by creatinine, were compared to plasma Po concentrations in non-conceptive ovarian cycles through two ovulations in four mares. High-performance liquid chromatography (HPLC) of urine from lutealphase mares and a pregnant zebra revealed an absence of significant concentrations of PdG and the presence of at least three immunoreactive compounds, all of which were more polar than PdG. The concentration of iPdG in the mare ranged from a nadir of approximately 3 ng/mg Cr at the time of ovulation to nearly 400 ng/mg Cr at the mid-luteal-phase peak and paralleled plasma Po concentrations. This non-radiometric assay for iPdG permits the assessment of ovulation, luteal formation and function, and luteolysis in unprocessed urine samples from domestic mares. Data from a single zebra indicate this approach also will permit simplified and non-invasive longitudinal studies of ovarian function among a wide range of Equidae.

	Title	*Urinary androgen concentrations and social status in two species of free ranging zebra (Equus burchelli* and E. grevyi).**			Type	Journal Article
	Year	1990	Publication	Journal of Reproduction and Fertility	Abbreviated Journal	J Reprod Fert
	Volume	88	Issue		Pages	127-133
	Keywords	zebra; testosterone; androgens; territoriality; social behaviour; dominance
	Abstract	In both species of zebra, breeding males had higher urinary androgen concentrations (ng androgens/mg Cr) than did non-breeding bachelor males (30.0 +/- 5.0 (N = 9) versus 11.4 +/- 2.8, (N = 7) in the plains zebra; 19.0 +/- 2.2 (N = 17) versus 10.7 +/- 1.2 (N = 14) in the Grevy's zebra). In the more stable family structure of the plains zebra (single male non-territorial groups) variations in androgen concentrations could not be ascribed to any measured variable. In the Grevy's zebra, androgen values were significantly lower in samples taken from territorial (breeding) males which had temporarily abandoned their territories (N = 4) and the urinary androgen concentration for a male on his territory was negatively correlated with the time since females last visited the territory.

	Title	The tale of the screaming hairy armadillo, the guinea pig and the marginal value theorem			Type	Journal Article
	Year	1990	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	39	Issue	6	Pages	1030-1050
	Keywords
	Abstract	Foraging by screaming hairy armadillos, Chaetophractus vellerosus, and guinea pigs, Cavia porcellus, was studied in the laboratory. The main question was whether patch exploitation varies with overall capture rate as predicted by the marginal value theorem (MVT). Armadillos in experiment I and guinea pigs in experiment II experienced a single travel time between depleting patches of two kinds: good and poor. There were two treatments, which differed in the quality of poor patches. MVT predicts that within a treatment, more prey should be taken from good than from poor patches and between treatments, good patches should be exploited in inverse relation to the quality of poor patches and poor patches should be exploited in direct relation to their own quality. In experiment III, guinea pigs experienced three treatments which differed in the travel requirement, while the two patch types remained the same. MVT predicts that within a treatment more prey should be taken from good than from poor patches and that between treatments more prey should be taken from both patch types as travel requirement increases. The qualitative predictions were supported in the three experiments. The quantitative fit was good but there was a bias towards more severe patch exploitation than predicted. The results indicate that in these species patch exploitation depends on overall food availability as predicted by the MVT when overall food availability differs either because of patch type composition or because of differences in travel requirement between patches.

	Title	The representation of social relations by monkeys			Type	Journal Article
	Year	1990	Publication	Cognition	Abbreviated Journal	Cognition
	Volume	37	Issue	1-2	Pages	167-196
	Keywords	Animals; Cercopithecus aethiops/psychology; Concept Formation; Dominance-Subordination; Female; Macaca fascicularis/psychology; Male; Social Behavior; *Social Environment
	Abstract	Monkeys recognize the social relations that exist among others in their group. They know who associates with whom, for example, and other animals' relative dominance ranks. In addition, monkeys appear to compare types of social relations and make same/different judgments about them. In captivity, longtailed macaques (Macaca fascicularis) trained to recognize the relation between one adult female and her offspring can identify the same relation among other mother-offspring pairs, and distinguish this relation from bonds between individuals who are related in a different way. In the wild, if a vervet monkey (Cercopithecus aethiops) has seen a fight between a member of its own family and a member of Family X, this increases the likelihood that it will act aggressively toward another member of Family X. Vervets act as if they recognize some similarity between their own close associates and the close associates of others. To make such comparisons the monkeys must have some way of representing the properties of social relationships. We discuss the adaptive value of such representations, the information they contain, their structure, and their limitations.
