En el presente trabajo se presentan los resultados de un análisis de regresión que relaciona el tamaño corporal frente a ocho caracteres osteológicos de G. galloti y G. atalntica. Se obderva una relación estadística positiva y significativa entre ellas, aunque los coeficientes de determinación (R2) indican niveles de ajuste más elevados en el caso de G. galloti que en G. atlantica. Además, se aportan datos preliminares sobre la relación: tamaño corporal vs. peso. Los distintos modelos propuestos pueden ser utilizados en estudios alimentarios de vertebrados depredadores que incluyen selección tallas (presas) de ambas especies, además de investigaciones paleontológicas.
In this paper we present the regression analysis between SVL and eight osteological variables in G. atlantica and G. galloti. Positive signigficant relationships can be observed among them, although coefficient of determination (R2) indicate better fits in the case of G. galloti than G. atlantica. Futhermore, preliminary data on the weiht-lenght relationships are shown. The proposed models can be used in predator vertebrate alimentary studies that include lizards size selection of both mentioned species and also in paleontological surveys.
Félix M. Medina and Juan C. Sánchez captured some of the lizards studied. P. Jordano assessed us with the statistical anslyses. J. A. Mateo and two anonimous referees gave us useful suggestions. Collecting was facilitated by permits issued by the Viceconsejería de Medio Ambiente del Gobierno de Canarias.
