J.B. French, I.C.T. Nisbet, H. Schwabl
2001, Comparative Biochemistry and Physiology, Part C: Toxicology & Pharmacology (128) 91-98
We looked for evidence for the hypothesis that exposure of female birds to polychlorinated biphenyls (PCBs) results in alteration of blood steroid hormone concentrations and alters subsequent hormone transfer of steroids to eggs. Eggs of three-egg clutches were collected from a PCB-exposed common tern (Sterna hirundo) colony (Ram Island, Buzzards...
Using open robust design models to estimate temporary emigration from capture-recapture data
William L. Kendall, R. Bjorkland
2001, Biometrics (57) 1113-1122
Capture-recapture studies are crucial in many circumstances for estimating demographic parameters for wildlife and fish populations. Pollock's robust design, involving multiple sampling occasions per period of interest, provides several advantages over classical approaches. This includes the ability to estimate the probability of being present and available for detection, which in...
