... of stress response. Our goal was to combine these approaches, focusing on populations of the symbiont-bearing foraminifer Amphistegina lessonii from Fernando de Noronha Archipelago (northeastern Brazil). Reef-rubble samples containing A. lessonii were collected at five sampling sites on the leeward side...
