Resumen:
The ocean plays an important role in the global cycle of mercury (Hg). As top predators, seabirds integrate exposure to contaminants over large geographic areas. To interprete what accumulated Hg levels mean, requires understanding life history, diet, foraging habitat, and the concentration in other biomarkers or abiotic substrates. Hg causes a wide range of effects on reproduction, including low egg weight, thinner shell, malformations of the embryo, decreased growth, and decreased chick survival. Feathers are useful to determine mercury (Hg) contamination. We evaluated the mercury concentration in feathers of 79 Magellanic penguins (Spheniscus magellanicus) age 1.5 years to 25 years at Punta Tombo, Argentina before and during their molt. Mercury ranged between
