Role of maternal odors on foraging behavior during postnatal development in a solitary subterranean rodent Ctenomys talarum

We investigated the role of maternal odors emanating from excretory deposits and/or glandular secretions during the postnatal development of foraging and related behaviors in young Los Talas' tuco-tucos (Ctenomys talarum), a solitary rodent, under seminatural conditions. During cafeteria tests,...
