“…In nine populations, the dorsal ¢ns and backs of freeranging bottlenose dolphins were photographed during ongoing boat-based studies using standard methods (e.g. Wells 1991;Wilson et al 1997b). In the tenth population (o¡ North Carolina), individuals were photographed during brief captures (similar to those described by Scott et al (1990)).…”

Experimental studies have highlighted the potential in£uence of contaminants on marine mammal immune function and anthropogenic contaminants are commonly believed to in£uence the development of diseases observed in the wild. However, estimates of the impact of contaminants on wild populations are constrained by uncertainty over natural variation in disease patterns under di¡erent environmental conditions. We used photographic techniques to compare levels of epidermal disease in ten coastal populations of bottlenose dolphins (Tursiops truncatus) exposed to a wide range of natural and anthropogenic conditions. Epidermal lesions were common in all populations (a¡ecting 460% of individuals), but both the prevalence and severity of 15 lesion categories varied between populations. No relationships were found between epidermal disease and contaminant levels across the four populations for which toxicological data were available. In contrast, there were highly signi¢cant linear relationships with oceanographic variables. In particular, populations from areas of low water temperature and low salinity exhibited higher lesion prevalence and severity. Such conditions may impact on epidermal integrity or produce more general physiological stress, potentially making animals more vulnerable to natural infections or anthropogenic factors. These results show that variations in natural environmental factors must be accounted for when investigating the importance of anthropogenic impacts on disease in wild marine mammals.

“…T he common bottlenose dolphin ( Twrsiops truncatus) is one of the most cosmopolitan cetaceans, ranging in diverse habitats from cold temperate to tropical waters in much of the Northern and Southern hemispheres (Wilson et al, 1997(Wilson et al, , 1999Rossbach and Herzing, 1999;Lusseau et al, 2003). Bottlenose dolphins inhabit small seas and open oceans (Bearzi et al, 1999), coastal waters (Hanson and Defran, 1993;Defran et al, 1999), and shallow protected bays (Wells et al, 1987).…”
