Abstract:
Movements of the tortoises Geochelone pardalis (mean body mass 4.0 kg) and Kinixys spekii (0.62 kg) were studied by thread-trailing. The mean daily movement distance of G. pardalis was 435 m, and the short-term home-range area was 26 ha. The values for K. spekii were 172 m and 1.9 ha, respectively. The area used by G. pardalis was significantly larger than would be produced by scaling up the movements of K. spekii in the same geometric pattern. Home-range areas were about the same size (K. spekii) or several times as large (G. pardalis) as those predicted for mammals of equal body mass. Ingest

Abstract:
Growth rings were measured in dead African leopard tortoises, Geochelone pardalis, collected in the seasonal tropics of Zimbabwe over an 11-year period. A series of Ford-Walford plots using growth measured from annuli showed that growth fitted a logistic by mass curve best, logistic by length and Gompertz curves less well, and a Bertalanffy curve least well. The Bertalanffy curve, often fitted to growth of chelonians, is characterised by particularly high growth rates of juveniles compared with larger individuals. It is suggested that this growth pattern is likely to be found in species showin

Abstract:
Most of the 42 living species of tortoise (Testudinidae) are herbivorous, feeding largely on vascular plants, with the exception of the genus Kinixys, which is omnivorous. A comparison of Kinixys spekii and Geochelone pardalis showed the following significant differences. The large intestine was shorter in K. spekii (86% of plastron length and 1.8% of body mass) than in G. pardalis (246 and 2.5%) and held a smaller proportion of the total gut contents (44 and 62%, respectively). The apparent digestibility coefficient (ADC) of organic matter was lower in K. spekii (77%) than in G. pardalis (82%

Abstract:
The influence of feeding juvenile female leopard tortoises (Geochelone pardalis, n=18) a commercially available, complete, extruded feed three (3) or seven days (7) per week on dry matter and digestible energy intake, apparent digestibility of dry matter, organic matter, gross energy and fiber fractions, animal body weight and measurements, digesta transit time, rate of passage, and indigestible fill was evaluated. Both feeding frequencies are commonly practiced with captive tortoises. When fed 7 compared to 3 days per week, dry matter and digestible energy intake was greater. Tortoises gain

Abstract:
The Family Testudinidae (Suborder Cryptodira) is represented by 40 species worldwide and reaches its greatest diversity in southern Africa, where 14 species occur (33%), ten of which are endemic to the subcontinent. Despite the strong representation of terrestrial tortoise species in southern Africa, and the importance of the Karoo as a centre of endemism of these tortoise species, there is a paucity of ecological information for most tortoise species in South Africa. With chelonians being protected in < 15% of all southern African reserves it is necessary to find out more about the ecological

Abstract:
The leopard tortoise (Geochelone pardalis) is the largest of the southern African tortoise species and has a wide distribution range. However, there is a lack of ecological and physiological information about the species, especially arid and semi-arid regions. The Nama-Karoo, an arid region of South Africa, is subject to large fluctuations in rainfall, food availability and ambient temperatures (Ta). This study focused on the thermal behaviour, thermoregulatory, digestive and metabolic plasticity of the leopard tortoise within the Nama- Karoo biome. Seasonal changes in activity patterns and bo
