Description

Habitat

Biome: Terrestrial [1].

Ecology: It characteristically inhabits 'Phrygana' and Macchia scrub , dense thorny scrub among rocky outcrops, but also a range of other vegetation types , from coastal dunes to olive groves, small-scale agricultural landscapes and damp areas. It ranges up to 1300m, but mostly occurs below 800m. It generally prefers drier, hotter areas than the sympatric T. hermanni boettgeri. (Willemsen 1995b; Bringsoe et al. 2001). Clutches consist of four to seven eggs , perhaps up to 15; females produce one to three clutches per year (review by Bringsoe et al. 2001). Animals require about eight to 14 years to reach maturity (review by Bringsoe et al. 2001). Testudo m. weissingeri inhabits both Phrygana (Spartan shrubby rocky areas) as well as more lush habitats such as olive groves with dense herbaceous ground cover (Artner 2000; Bringsoe et al. 2001: 309-311). This taxon ranges from near sea level to about 1,300m altitude (Mueller1908, Bour 1996, in Bringsoe et al. 2001: 311), and feeds on a variety of herbs (Bour 1996, in Bringsoe et al. 2001: 312). Its clutch size is a maximum of four, perhaps six eggs (Bour 1996, in Bringsoe et al. 2001: 314; Artner 2000).[1].

Notes

Name Status: Accepted Name .

Comment: Lectotype : MZUS 143 designated by Bour 1987:118. Holotype: MNHN 1989: 3317 (weissingeri) Testudo marginata and Testudo graeca ibera have been reported to produce viable hybrids (STEMMLER-GYGER 1963, 1964). Testudo weissingeri differs from T. marginata in size and coloration . However, the presence of thigh-spurs is not a reliable character to distinguish between the two species. It has been postulated that T. weissingeri is a dwarf form of T. marginata, the largest European tortoise species. FRITZ et al (2005) detected no differentiation between T. marginata and T. weissingeri. They conclude that T. weissingeri is not a distinct evolutionary unit and suggest that its small size is the result of suboptimal environmental conditions with limited resources . As a consequence, T. weissingeri was synonymized with T. marginata.

The recognised subspecies are marginata, sarda, and weissingeri. The subspecies weissingeri was elevated to species rank by Bour (1996), but it is frequently considered a to be subspecies of Testudo marginata. It is not even accorded subspecies status by some authors , but it was validated as a full species by Perala (2002a). In this account we include weissingeri within T. marginata, pending resolution of its taxonomic status.[1].
