Abstract

A field study of Tropidurus delanonis was carried out on an uninhabited island (Hood) of the Galapagos Archipelago over 18 months. The purpose of the study is to show the interrelation between social structure, behaviour and ecological aspects of the iguanid lizard Tropidurus delanonis. Five lizard categories are distinguished and the interrelation between colouration type and behaviour is shown. Data are given on population structure, composition and flexibility, reproductive cycle, clutch size, ontogeny and changes in colouration and behaviour. Detailed maps show the distribution of female and male territories and the area occupied by those male male that attempt to acquire a territory. The biomass is calculated for all categories in resect to total area available and to favorable and unfavorable areas within the observation area. The significance of various colouration types was tested experimentally.

摘要

在加拉帕戈斯群岛的一个无人居住的岛屿（胡德岛）上，对德拉诺尼角蜥进行了为期18个月的实地研究。该研究的目的是展示鬣蜥科蜥蜴德拉诺尼角蜥的社会结构、行为和生态方面之间的相互关系。区分了五种蜥蜴类别，并展示了体色类型与行为之间的相互关系。给出了关于种群结构、组成和灵活性、繁殖周期、窝卵数、个体发育以及体色和行为变化的数据。详细地图显示了雌性和雄性领地的分布以及试图获取领地的雄性个体所占据的区域。针对观察区域内的可用总面积以及有利和不利区域，计算了所有类别的生物量。通过实验测试了各种体色类型的重要性。
