Application extraterritoriale du droit international des droits de l'homme

Les obligations de l'Etat en matière de droits de l'homme s'étendent-elles au-delà de ses frontières? Le sujet prend une importance considérable actuellement: interventions militaires à l'étranger, opérations de paix, occupation militaire, centres de détention à l'étranger, mouvements séparatistes soutenus par un Etat étranger, éloignement des étrangers, entraide judiciaire et administrative internationale, exequatur de décisions étrangères violant les droits de l'homme... Ces thèmes, et d'autres, sont abordés dans l'ouvrage sous l'angle du Pacte ONU II, de la CEDH, et de la Convention et la Déclaration américaines dans une approche comparative et systématique. L'ouvrage analyse en détail la jurisprudence et la pratique internationales relatives à ces instruments. L'auteur est avocat au Barreau du Canton de Vaud (Lausanne) et titulaire d'un LL.M. de l'Université de Cambridge.

Food availability affects the maternal transfer of androgens and antibodies into eggs of a colonial seabird.

Mothers can improve the quality of their offspring by increasing the level of certain components in their eggs. To examine whether or not mothers increase deposition of such components in eggs as a function of food availability, we food-supplemented black-legged kittiwake females (Rissa tridactyla) before and during egg laying and compared deposition of androgens and antibodies into eggs of first and experimentally induced replacement clutches. Food-supplemented females transferred lower amounts of androgens and antibodies into eggs of induced replacement clutches than did non-food-supplemented mothers, whereas first clutches presented no differences between treatments. Our results suggest that when females are in lower condition, they transfer more androgens and antibodies into eggs to facilitate chick development despite potential long-term costs for juveniles. Females in prime condition may avoid these potential long-term costs because they can provide their chicks with more and higher quality resources.
