“…were among the chelonians examined at the VMTH‐UCD, whereas this genus comprised more than half of the chelonians examined at the UDPM‐ENVN. While in a recent report the USA was responsible for more of the import trade of this genus than most other countries, including France, it is possible that the closer proximity of France to the primary Testudo ‐exporting countries of Turkey, the former Soviet Union, the former Yugoslavia and Morocco was responsible for this species difference between the two institutions 10 . With the restrictions on the importation of T. graeca and T. hermanni , importation of T. horsfieldi has increased 10 .…”

Despite the various species differences in the patient population between the two institutions, it is interesting to note that the percentage of referral cases was virtually the same for both (13–15%).…”

This retrospective study reviews the medical records of 301 reptiles with dermatological lesions that were examined at the Veterinary Medical Teaching Hospital, University of California at Davis (VMTH-UCD) and the Unité de Dermatologie-Parasitologie-Mycologie, Ecole Nationale Vétérinaire de Nantes (UDPM-ENVN) from 1 January 1992 to 1 July 2008. The most common reptile groups differed between the two hospitals, with lizards being the most common at the VMTH-UCD and chelonians at the UDPM-ENVN. At the VMTH-UCD, boa constrictors (Boa constrictor), ball pythons (Python regius) and other Python species were over-represented, and box turtles (Terrapene carolina) were under-represented in the dermatological lesion caseload. When institutional data were combined, 47% of all reptiles at both institutions with confirmed or suspected cases of sepsis had petechiae, with the highest association seen in chelonians at 82%. Dependent on institution and reptile group, from 29% to 64% of the cases had underlying husbandry issues. Sixty-two per cent of all cases were alive at final status. Veterinarians treating reptiles with skin disease should be aware of the following: (i) that boa constrictors and Python species may be predisposed to dermatological lesions; (ii) that client education is important for proper husbandry; and (iii) that there is a possible association between petechiae and sepsis, especially in chelonians. The conjectural association between certain skin lesions and sepsis remains to be confirmed by systematically derived data that demonstrate a causal relationship between the two.

“…On the other hand, historical factors have not been included in our modelling approach. These factors can be especially relevant for T. graeca which has suffered intensive collection for pet trade in recent decades (see above, Pérez et al 2004;Türkozan 2008).…”

Linking local ecological knowledge and habitat modelling to predict absolute species abundance on large scales

2009

Assessing the spatial structure of abundance of a species is a basic requirement to carry out adequate conservation strategies. However, existing attempts to predict species abundance, particularly in absolute units and on large scales, are scarce and have led to weak results. In this work we present a scheme to obtain, in an affordable way, a predictive model of absolute animal abundance on large scales based on the modelling of data obtained from local ecological knowledge (LEK) and its calibration. To exemplify this scheme, we build and validate a predictive absolute abundance model of the endangered terrestrial tortoise Testudo graeca in Southeast Iberian Peninsula. For that purpose, we collected distribution and relative abundance data of T. graeca using a low cost methodology, such as LEK, by means of interviewing shepherds. The information from LEK was employed to build a predictive habitat-based model of relative abundance. The relative abundance model was transformed into an absolute abundance model by means of calibration with a classical absolute abundance sampling method such as distance sampling. The obtained absolute abundance model predicted the observed absolute abundances values well in independent locations when compared with other works (R 2 = 36%) and thus can offer a cost-effective predictive ability. Our results show that reliable habitatbased predictive maps of absolute species abundance on regional scales can be obtained starting from low cost sampling methods of relative abundance, such as LEK, and its calibration.

“…Human impact affects all tortoise populations directly or indirectly (Türkozan et al, 2008). The easily visible effects of human impact on T. graeca are shown on the carapace and plastron as blows or destruction of the scutes (Tuegel and Weise, 2006).…”

Fluctuating asymmetry has been proposed as a useful noninvasive tool for detecting the influence of the environment on body development. In the present study, we used digital images to estimate the fluctuating asymmetry of the plastron in an isolated Testudo graeca population in Dobrogea, Romania. We extracted data from the photos regarding the area, height, and width of 3 plastron scutes. A total of 155 adult tortoises analysed showed reduced variation in plastron asymmetry and no significant relationship was detected between fluctuating asymmetry and sex or body size. We suggest that fluctuating asymmetry may be an individual trait, with no predictive value at the population level.
