AbstractThe species and subspecies of W Palaearctic tortoises include six, which are widespread in southern Europe, North Africa, the Middle East and Central Asia, and four with restricted ranges in the Mediterranean region. The Central Asian Testudo (Agrionemys) horsfieldii GRAY overlaps with Testudo graeca zarudnyiNIKOLSKY in Iran and Afghanistan. The distributions of the remainder border the Mediterranean Sea. Their survival is threatened directly or indirectly by human activity over many years and include habitat destruction (urbanization, touristic development, road-building, scrubland fires and agriculture), bulk pet and food trade collection for export to NW Europe (Testudo graeca graeca L., Testudo graeca ibera PAL-LAS, Testudo hermanni hermanni GMELIN, T. (A.) horsfieldii and sometimes Testudo marginata SCHOEPFF), isolation of populations with restricted ranges (Testudo hermanni robertmertensiWERMUTH, Testudo (Pseudotestudo) kleinmanni LORTET, T. marginata and Testudo graeca floweri BODENHEIMER), and desertification, especially in the Saharan encroachment zone of northern Africa from wood burning, animal grazing and rainfall decrease (T. g. graeca and T. (P.) kleinmanni). A circum-Mediterranean investigation would establish the population status of all species and their habitats. Countries of the Council of Europe and European Economic Community by ratifying C.I.T.E.S. (Washington Convention 1973) have established the extent of the bulk trade. This should only be allowed in captive-bred animals which, like other domestic pets, could be commercially farmed, probably by necessity in the Mediterranean bioclimatic zone.

Zusammenfassung Gegenstand und Ziel: Erstellung von 20 Blutparametern in Deutschland gehaltener mediterraner Landschildkröten und Vergleich der erhaltenen Parameter zwischen vier unterschiedlichen Landschildkrötenspezies. Material und Methoden: Bei 61 mediterranen, in Deutschland gehaltenen Landschildkröten wurden nach Blutentnahme aus der dorsalen Kokzygealvene hämatologische und blutchemische Referenzwerte von 20 Parametern erstellt. Die Untersuchung erstreckte sich auf Nachzuchttiere oder länger als drei Jahre im Besitz befindliche Tiere aus fünf kontrollierten Beständen. Alle Probanden wurden im Frühjahr bis Spätsommer im Freiland gehalten und hielten regelmäßig Winterschlaf. Die Fütterung der Schildkröten erfolgte ausschließlich mit pflanzlicher Kost. Die 61 klinisch unauffälligen Landschildkröten gehörten den Spezies Testudo marginata (Breitrandschildkröte; n = 16), Testudo graeca (Maurische Landschildkröte; n = 15), Testudo hermanni (Griechische Landschildkröte; n = 22) und Testudo horsfieldii (Russische Steppenschildkröte; n = 8) an. Ergebnisse: Median, Minimal- und Maximalwerte, sowie p-Werte wurden für Hämatokrit, Alanin-Aminotransferase, Aspartat-Aminotransferase, Glutamat-Dehydrogenase, alkalische Phosphatase, Kreatinkinase, Harnsäure, Harnstoff, Cholesterin, Glukose, Fruktosamin, Gesamtbilirubin, Gesamteiweiß, Albumin, Cholinesterase, Natrium, Kalium, Gesamtkalzium, ionisiertes Kalzium und anorganisches Phosphat ermittelt. Schlussfolgerung und klinische Relevanz: Bei 10 der untersuchten 20 Parameter konnten statistisch signifikante speziesspezifische Unterschiede festgestellt werden. Die Ergebnisse weisen darauf hin, dass bei der Interpretation der Blutparameter so genannter „mediterraner Landschildkröten” unbedingt eine Speziesdifferenzierung stattfinden sollte.

This work shows the value of osseous growth marks for age determination in two terrestrial chelonia, Testudo hermanni and Testudo graeca. Careful histological observation of long bones proves that concentric rings show a yearly growth pattern; we have already described similar findings in amphibians, snakes, and lizards.We confirm these data first by the observation of some wild turtles of known age and of a close correlation between the number of bone rings and the number of rings on the cornified scutes. We also confirm in both species that scutes have a yearly growth rhythm and we conclude that bone growth marks provide a good criterion for age determination. Resorption destroys some juvenile rings; we propose a calculation to evaluate the number of resorbed lines to obtain the true individual age.In our turtles, scute growth rings allowed age determination until sexual maturity. With osseous growth marks, we were able to extend accurate ageing until the 20th year. We also established that sexual maturity occurs when animals are 12 or 13 years old in both species, with little difference between males and females.

AbstractTwo tortoises, Testudo graeca ibera Pallas, 1814 and Testudo hermanni boettgeri (Mojsisovics, 1889), inhabit Bulgaria. Certain features normally used for their identification, such as division of the supracaudal scute (divided in T. h. boettgeri; undivided in T. g. ibera), are not absolute. Seven whole shells of T. g. ibera and eleven of T. h. boettgeri were studied, and also a large series of shell fragments of both species. Based on analysis of 44 shell characters, T. h. boettgeri was distinguished by the following: maximal width of vertebral scute V clearly greater than maximal widths of other vertebral scutes; width of vertebral scutes II, III and IV smaller than width of pleural scutes I, II and III; medial length of pectoral scute equal or slightly greater than half the medial length of the hypoplastron; hypo-xiphiplastral suture distant from the corner of the inguinal notch; medial length of xiphiplastron less than maximal width (in females), or nearly half the maximal width (in males).
