Agnieszka Majer and Kamila Karpicka-Ignatowska received PRELUDIUM grants financed by the National Science Centre in Poland. Agnieszka will study competition-dispersal trade-off in phytophagous mites. Kamila will find out whether passively dispersed herbivores rely on semiochemical cues when undertaking dispersal and how the ability to detect kairomones depends on the level of host specialization and environmental heterogeneity.
