 | | Differences in the mean size of adult males and females, or sexual size dimorphism (SSD), are widespread in the animal kingdom (Darwin 1871), and considerable effort has been directed toward understanding the evolution of this phenomenon (e.g., Darwin 1871, Schoener 1967, Selander 1972, Trivers 1972, 1976, Clutton-Brock et al. |
 | | Between December 1991 and September 19941 studied the iguanian lizard Microlophus occipitalis in western Ecuador with the aim of understanding the proximate causes of SSD in a single population. |
 | | Microlophus occipitalis is a small (50-80 mm snout-vent length), insectivorous lizard found in the arid coastal desert and thorn scrub areas of southwestern Ecuador and northwestern Peru (Dixon and Wright 1975, Carpenter 1977). |
