Physiological costs during maternal care in Pardosa saltans (Araneae, Lycosidae)

Abstract

International audienceMany arachnids, like other terrestrial arthropods, provide extensive maternal care. Few studies have quantified the underlying physiological costs of maternalcare. We investigated how maternal care affects the free-moving wolf spider’s (Pardosa saltans) energy requirements. Our aim was to evaluate the contributions of protein, glucose and lipids to the maintenance of female P. saltans’ energy
