We analyzed 15 polychlorinated biphenyls (PCBs) and five organochlorine pesticides (OCPs) in fat tissue of 27 loggerhead sea turtles (Caretta caretta) from eastern Adriatic Sea with the curved carapace length ranging from 25.0 to 84.5 cm. The PCB profile was dominated by hexa- and hepta-chlorinated congeners, with PCB-153 (median: 114.9 ng g−1 wet mass), PCB-138 (80.0 ng g−1 w.m.), and PCB-180 (26.7 ng g−1 w.m.) detected with the highest levels. Toxic mono-ortho congeners PCB-118, PCB-105 and PCB-180 with dioxin-like toxicity were found in >70% samples. 4,4′-DDE (81.0 ng g−1 w.m.) prevailed the OCP signature, accounting for 80% of the total DDTs. A significant increasing trend in accumulation with size was found for PCB-52 (rs = 0.512, p < 0.01) and PCB-114 (rs = 0.421, p < 0.05). Comparison of our results with organochlorine contaminant (OC) pattern in some prey taxa suggest that contamination occurs primarily through the food web, with biomagnification factors of 0.14-6.99 which were positively correlated with the octanol-water partition coefficient (log Kow; p < 0.05). This study, based upon a fairly large sample size collected mostly from incidentally captured animals over a short time period (June 2001-November 2002), present a temporal snapshot of OC contamination in wild, free-ranging loggerheads from Adriatic feeding grounds and provide a baseline for monitoring the regional OC trends in this endangered species. 相似文献

Assessment of the daily foraging areas of spotted deer that belonged to groups of different sizes was performed in the Ussuriiskii Nature Reserve (Primorskii krai) during the period with permanent snow cover. Calculations showed that the foraging area size per individual was inversely correlated to the number of individuals in the group. We hypothesized that large groups of Spotted deer are capable of more efficient use of the living range for foraging than the groups composed by smaller numbers of individuals. 相似文献
