Thesis (M.Sc. (Zoology)) --University of Limpopo, 2001.<br>A South African rehabilitation centre for illegally kept vervet monkeys required an evaluation of the genetic status of vervet monkeys , to determine whether animals from different geographical areas may be kept in the same enclosures and mixed during release back into the wild. Animals originating from three geographical regions (the former Transvaal, KwaZulu-Natal and the Eastern Cape) were studied using biochemical genetic and morphological approaches to address this question.

Abstract:

The principle objective of this study was to describe and record all the gathering and processing skills of vervet monkeys for a variety of different foods. The study was conducted on two troops of vervet monkeys living in the Palmiet Valley, Natal, South Africa. There was sufficient data to analyze the processing of four foods of differing complexity; termites, leaf shoots, sugarcane and fruit. Milton (1988) proposed that the intellectual difficulties of finding and processing food led to the evolution of intelligence. In the only study of food processing skill, Byrne and Byrne (1993) showed

Abstract:

Fragile X syndrome (FXS) is the leading cause of inherited mental retardation and developmental delay. In the vast majority of cases, this X-linked disorder is due to a CGG expansion in the 5' untranslated region of the fmr-1 gene and the resulting decreased expression of its associated protein, FMRP (Fragile X associated Mental Retardation Protein). FXS is characterized by a number of cognitive, behavioural, anatomical, and biological abnormalities. This monogenic disorder provides a unique opportunity to study the consequence of a mutation in a single gene on the development and proper funct

Matrilineal ranks remained unchanged for the first 7 years (stable period), reversed on several occasions over the next 3.5 years (unstable period), and have re-stabilised for a further 3.5 years to present date.

Self-directed behaviours (SDB) were recorded as a behavioural indicator of arousal in free-ranging vervet monkeys (Chlorocebus aethiops) inhabiting the Klein Karoo of South Africa. Measurement of SDB allowed for changes in arousal to be correlated with particular social situations, potentially providing insight into how monkeys perceive their social world. The research presented here is divided into three core chapters demonstrating that 1) arousal is influenced to a greater extent by degree of association than by hierarchical rank, 2) that an individual‟s level of arousal is influenced by its

Las frutas y hortalizas presentan compuestos bioactivos beneficiosos para la salud humana. El desarrollo de variedades con un mayor contenido en este tipo de compuestos es de interés, ya que contribuye a satisfacer una demanda creciente por parte de los consumidores por productos con propiedades funcionales. Dentro de las hortalizas, la berenjena (Solanum melongena) presenta una alta actividad antioxidante, fundamentalmente derivada de su alto contenido en polifenoles, y se ha demostrado que presenta efectos beneficiosos para la salud humana.

Abstract:

Par sa différence et par sa similitude, l’homme à la peau foncée interpelle les anciens qui, dès les savants grecs, ont voulu trouver des raisons géographiques et climatiques, c’est-à-dire ‘scientifiques’, à son altérité. C’est le monde romain antique qui a été choisi comme cadre du présent travail. On y utilise un corpus de textes littéraires, historiques et philosophiques latins, considérés dans un éventail chronologique large (du IIe s. av. J.-C. au Ve s. ap. J.-C.), sans s’interdire éventuellement la comparaison avec les référents grecs. Le travail s’appuie sur une démarche lexicologique,

Abstract:

This study explored the organizing principles of female sociality in free-ranging vervet monkeys (Chlorocebus aethiops) inhabiting the Klein Karoo, South Africa. Females groomed more than males, grooming peaked at the end of the day and less grooming occurred during the mating season. Although females competed over food, they did not compete over grooming partners, rarely formed coalitions and did not trade grooming against other activities. Instead, they maintained grooming whilst trading between feeding and resting and feeding and moving. Despite seasonal shifts in food competition, grooming

La progression vers le SIDA est attribuée à une activation immunitaire chronique. L'étude de l'infection par le virus de l'immunodéficience simienne (SIV) pathogène chez le Macaque (Mac) et non pathogène chez le singe vert d'Afrique (AGM), a montré une inflammation plus modérée chez l'AGM que chez le Mac en phase aiguë. Nous avons émis l'hypothèse que les niveaux d'inflammation lors de la phase aiguë d'une infection VIH-1 (PHI) sont prédictifs du profil de progression vers le SIDA. Nous avons alors étudié: (i) les niveaux d'inflammation en PHI selon le profil de progression vers le SIDA, (ii)

Abstract:

The permanent coresidence of males within a troop is unusual but occurs in vervet monkeys. Several hypotheses have been projected to explain the coexistence of male vervets (predation risk, breeding season length) but these hypotheses fall short in explaining the multimale nature of vervet monkeys. In order to determine the explanation for coresiding males, I collected male behavioural data from two troops over the course of nine months. My dataset was divided into two categories, male-male interactions and female-male interactions. The male-male data indicate that breeding season is the most

Les changements environnementaux liés à l’activité humaine influent sur le comportement de la faune sauvage. L’espèce humaine exploite maintenant l’ensemble des écosystèmes où résident de nombreuses espèces animales. Cette cohabitation se caractérise par un chevauchement des habitats entre les espèces, dont les capacités d’adaptation ne sont pas toutes équivalentes. On remarque alors dans certaines situations, des degrés de flexibilité selon les espèces ainsi que le développement des relations homme/animal importantes au dépend de l’un ou de l’autre des protagonistes.

Abstract:

The movements of two vervet monkey troops were studied to determine whether they optimize their rate of food intake in relation to seasonal energy availability. The effect of variation in habitat structure on the troops’ foraging strategies while utilizing temporally and spatially distributed resources was determined. Troop home range boundaries were delineated, the various plant communities and species utilised by the troops identified and classified, and variations in home range and vegetation structure were reported. The diets of the troops were determined and compared. Effects of coexisten

The aim of this study is to assess the advantages and disadvantages to all the troop members, of vervet males remaining in heterosexual groups outside the mating season. Extensive data on time budgeting and social interactions have been obtained for both a caged and a free-ranging undisturbed troop. Some of the potential advantages males provide to other members of the troop are: improvement in predator detection, maintenance of the troop unity and interference in agonistic interactions involving females and immatures. Special emphasis is placed on the analysis of seasonal changes in agonistic
