Sexual Selection and Signalling in the Lizard Platysaurus Minor
SEXUAL SELECTION AND SIGNALLING IN THE LIZARD PLATYSAURUS MINOR Belinda Ann Lewis A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2006 I declare that this dissertation is my own unaided work. It is being submitted for the degree of Master of Science in the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination in any other University. ________________________ Belinda A. Lewis 6th day of December 2006 i ABSTRACT Sexual selection may influence aspects of male morphology associated with territoriality, female choice, aggression and contest success. Attributes that are most commonly selected for include body size, condition, weaponry, endurance and bright coloration. I investigated the relationships between morphology, use of space and home range quality, and access to females. Specifically, I examined the relationships between colour, body size and condition, and whether morphology could predict aggression or contest success. Colour spectral data were analyzed using both traditional measures of colour (hue, chroma, brightness) and principal components. Males with darker, more saturated chests, and more saturated throats, had larger home ranges. Home range quality, as determined by refuge number and prey availability, was associated with blue chests and blue throats and chests, respectively. Males with larger home ranges had higher numbers of associated females and spent more time courting females. Larger males in better condition had darker, more saturated chests. Males in better body condition were also more aggressive. There was a consistent trend for larger males to win more contests, but this relationship was only significant in analyses using traditional measures of colour. -
Morphological and Ecological Correlates of Bite Force in the Rockdwelling Lizards Ouroborus Cataphractus And

With 4 figures Under pressure: morphological and ecological correlates of bite force in the rock-dwelling lizards Ouroborus cataphractus and Karusasaurus polyzonus (Squamata: Cordylidae) Downloaded from https://academic.oup.com/biolinnean/article/111/4/823/2415797 by guest on 28 September 2021 CHRIS BROECKHOVEN* and P. LE FRAS N. MOUTON Department of Botany & Zoology, Stellenbosch University, Private Bag X1, Matieland 7602, Stellenbosch, South Africa Received 31 October 2013; revised 2 December 2013; accepted for publication 2 December 2013 Rock-dwelling lizards are hypothesized to be highly constrained in the evolution of head morphology and, consequently, bite force. Because the ability to generate a high bite force might be advantageous for a species’ dietary ecology, morphological changes in head configuration that allow individuals to maintain or improve their bite force under the constraint of crevice-dwelling behaviour are to be expected. The present study addressed this issue by examining head morphology, bite force, and a number of dietary traits in the rock-dwelling cordylid lizards Ouroborus cataphractus and Karusasaurus polyzonus. The results obtained show that O. cataphractus has a larger head and higher bite force than K. polyzonus. In K. polyzonus, head width, lower jaw length, and jaw closing-in lever are the best predictors of bite force, whereas head height is the main determinant of bite force in O. cataphractus. Although the observed difference in bite force between the species does not appear to be related to dietary patterns or prey handling, the prey spectrum available for intake was greater in O. -

Causes and Consequences of Body Armour in the Group-Living Lizard, Ouroborus Cataphractus (Cordylidae)
Causes and consequences of body armour in the group-living lizard, Ouroborus cataphractus (Cordylidae) by Chris Broeckhoven Dissertation presented for the degree of Doctor of Philosophy in the Faculty of Science at Stellenbosch University Supervisor: Prof. P. le Fras N.

March 2015 Copyright © 2015 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za ABSTRACT Cordylidae is a family of predominantly rock-dwelling sit-and-wait foraging lizards endemic to southern Africa. The significant variation in spine length and extent of osteoderms among taxa makes the family an excellent model system for studying the evolution of body armour. Specifically, the Armadillo lizard (Ouroborus cataphractus) offers an ideal opportunity to investigate the causes and consequences of body armour. Previous studies have hypothesised that high terrestrial predation pressure, resulting from excursions to termite foraging ports away from the safety of the shelter, has led to the elaboration of body armour and a unique tail-biting behaviour. The reduction in running speed associated with heavy body armour, in turn, appears to have led to the evolution of group-living behaviour to lower the increased aerial predation risk. -
A Taxonomic Revision of the South-Eastern Dragon Lizards of the Smaug Warreni (Boulenger) Species Complex in Southern Africa, Wi

ABSTRACT A recent multilocus molecular phylogenyofthelargedragonlizardsofthegenus Smaug Stanley et al. (2011) recovered a south-eastern clade of two relatively lightly- armoured, geographically-proximate species (Smaug warreni (Boulenger, 1908) and S. barbertonensis (Van Dam, 1921)). Unexpectedly, S. barbertonensis was found to be paraphyletic, with individuals sampled from northern Eswatini (formerly Swaziland) being more closely related to S. warreni than to S. barbertonensis from the type locality of Barberton in Mpumalanga Province, South Africa. Examination of voucher specimens used for the molecular analysis, as well as most other available museum material of the three lineages, indicated that the ‘Eswatini’ lineage—including populations in a small area on the northern Eswatini–Mpumalanga border, and northern KwaZulu–Natal Province in South Africa—was readily distinguishable from S. barbertonensis sensu stricto (and S. warreni) by its unique dorsal, lateral and ventral colour patterns. In order to further assess the taxonomic status of the three populations, a detailed Submitted 26 September 2019 Accepted 7 January 2020 morphological analysis was conducted. Multivariate analyses of scale counts and Published 25 March 2020 body dimensions indicated that the ‘Eswatini’ lineage and S. -

Potential Invasion Risk of Pet Traded Lizards, Snakes, Crocodiles

The pet trade in recent years became the most important pathway for the introduction of non-indigenous species of reptiles worldwide. Therefore, we decided to determine the most common species of lizards, snakes, and crocodiles traded as pets on the basis of market surveys in the Czech Republic, which is an export hub for ornamental animals in the European Union (EU). Subsequently, the establishment and invasion potential for the entire EU was determined for 308 species using proven risk assessment models (RAM, AS-ISK). Species with high establishment potential (determined by RAM) and at the same time with high potential to significantly harm native ecosystems (determined by AS-ISK) included the snakes Thamnophis sirtalis (Colubridae), Morelia spilota (Pythonidae) and also the lizards Tiliqua scincoides (Scincidae) and Intellagama lesueurii (Agamidae).
