Abstract

Daily activity patterns of Testudo hermanni in summer are described for two sites, Alyki, a coastal heathland in Greece, and the Massif des Maures, a woodland in France. Activity was bimodal in the former and unimodal in the latter. Habitat type was thought to be more important than latitude and climate in accounting for this pattern. AtAlyki there was a sex ratio of encounters of2. 7 ♂: 1 ♀ in summer, but no differences between the sexes in daily activity pattern. In the Massif des Maures, the ratio varied through the season, from 0.5 ♂: 1 9 in June, to 2.6 ♂: 1 9 in September, suggesting seasonal differences in activity of the sexes. Population density at Alyki was 5 times greater than in the Massif des Maures, yet sighting frequency was similar. This was accounted for by the increased ease offinding active animals in the woodland from the noise they made in the leaf litter.

Abstract

The mean body temperature of T. hermanni in woodland in France was 28.5 °C (August 1981). Body temperatures were elevated above air temperature and indirect evidence for basking and selection of an optimal microenvironment is discussed.
