| Prevalence of Influenza A Antibodies in Yellow-Legged Gull (Larus michahellis) Eggs and Adults in Southern Tunisia. | Abstract Investigating the prevalence of anti-influenza A viruses (AIV) antibodies in wild birds can provide important information for the understanding of bird exposure to AIV, as well as for prevention purposes. We investigated AIV exposure in nature by measuring the prevalence of anti-AIV antibodies in the nests and adults of an abundant and anthropophilic waterbird species common around the Mediterranean sea, the yellow-legged gull (Larus michahellis). Sampling took place in two colonies l ... | 2011 | 21919723 |
| tracing waterbird exposure to total mercury and selenium: a case study at the solar saltworks of thyna (sfax, tunisia). | saltworks have emerged as important alternative/complementary feeding habitats for avifauna. however, the consequences of such habitat shifts in terms of changes in exposure to contaminants are poorly understood. we evaluated the exposure of the waterbird community breeding at the saltworks of thyna (tunisia) to total hg (thg) and se according to their differential use of saltworks dietary resources, as revealed by δ¹³c and δ¹⁵n values in their eggs (included species [n] -sorted according to inc ... | 2011 | 21663312 |
