  Se presentan los resultados preliminares de la aplicación del método etológico observacional al estudio de la actividad en lagartos de Tenerife en dos zonas de la isla con características ecológicas diferentes (Malpaís de Güimar y en la periferia del Parque Nacional del Teide) y en dos tramos horarios (mañana y mediodía). Durante transectos elegidos al azar, se contabilizó el número de ejemplares activos de cada sexo y categoría, así como el tipo de pauta de comportamiento que realizaban. En ambas zonas fue siempre mayor el número de ejemplares machos activos que el de hembras o juveniles. El número total de animales

  We present preliminary results on the application of the observational ethological method to the study of activity of lizards from Tenerife in two habitats of the island with different ecological characteristics: Malpaís de Güimar (SE of the island) and the periphery of Teide National Park (centre of the island), and in two daily times. We counted the number of animals of each sex and category while walking in transects with hazardously chosen directions. The behaviour pattern performed by each observed animal was also scored.

  The results show that there were always more active males than females or juveniles in both zones. The number of total active animals per unit area and time was inversely related to the environmental temperature in Teide National Park. In Malpaís de Güimar the higher number of animals was recorded in intermediate temperatures between maximum and minimum ones. The number of observed animals was greater at midday than in the morning in Malpaís de Güimar, but the contrary occurred at Teide N.P. The results support the finding in other species of a higher activity level in males and also suggest a differential activity pattern in relation to environmental temperature in both zones studied.
