Transfer of selenium from prey to predators in a simulated terrestrial food chain
Little is known about the accumulation and effects of selenium in reptiles. We developed a simplified laboratory food chain where we fed commercial feed laden with seleno- d, l-methionine (30 μg/g dry mass) to crickets ( Acheta domestica) for 5–7 d. Se-enriched crickets (∼15 μg/g Se [dry mass]) were...
