Importance of plant sex for ecosystem services
Many plants are dioecious, i.e. having individuals with only male or female flowers. The fact that male and female plant individuals of the same species vary in quality for herbivores has received increased attention over the past years. However, the effect of plant sex on pollinators and carnivores is largely unexplored. Salix (willow), which is used as a bioenergy crop in short rotation coppice, will be used as model plant. Pollinators respond positively to the presence of willows since willow catkins are their principal food source in early spring. Carnivorous bugs are important as biocontrol agents of detrimental insect herbivores. The biocontrol may be enhanced by selecting willow genotypes that promote natural enemies ? for example by providing nutritious floral nectar. All willow species are dioecious with male and female catkins appearing on different plants. As only one genotype (clone) normally is grown in one field, this means that biocontrol agents and pollinators only have access to male or female catkins, depending on the sex of the particular willow clone used in that field. Both biocontrol agents and pollinators visit the catkins of willows but the value of the rewards they get has not been quantified. The first aim is to elucidate the importance of willow sex for the performance and effectiveness of three biocontrol agents, representing different foraging strategies. The second aim is to elucidate the importance of willow sex for the pollination success in adjacent crops, particularly strawberries.
