Primary data for article: Lundgren, Lázaro and Totland "Effects of experimentally simulated pollinator decline on recruitment in two European herbs". Accepted in Journal of Ecology in January 2015. Here we used a novel experimental approach that simulates pollinator decline to assess the effects of a 4-year reduction in pollinator availability on reproduction and recruitment in two common European herbs, Centaurea jacea and Leucanthemum vulgare. Our experiment reduced pollinator availability without artificially affecting quality components of the pollination process. Therefore, this approach may represent a realistic simulation of a pollinator decline. To our knowledge, this is the first study that uses an experimental reduction in pollinator visitation to assess its effects on population recruitment in plants. This study shows that a large pollinator decline may affect population densities, but only in populations where seedling recruitment is limited by seed production. Our results also highlight the importance of going beyond visitation rates and seed production to study the impact of pollinator decline on plant populations.
