| Summary: | Variation of the preferred temperatures (Tp) by the Moorish gecko (Tarentola mauritanica) in spring was analysed in a population from NE Iberia. Ten adult specimens were exposed to a thermal gradient and Tp was measured at seven time intervals between 16 and 24 h. Tp values were low (23.44 ± 0.61 ºC, 20.7-26.9 ºC, mean ± SE, range) but geckoes gradually increased Tps between late afternoon and early evening. Surprisingly, mean, maximum and minimum Tps inversely correlated with the body size (SVL), but the results of the analyses remained after size correction. Compared to a previous study carried out in summer, Tps found here were much lower but diel variation persisted. Such patterns are more similar to other nocturnal or crepuscular geckonids rather than to the well-studied diurnal lacertids living in the same sites. Specifically, Tp seems to be more plastic and the relationships with body size are opposite. Possible adaptive explanations and guidelines for further work are suggested. |
