16. Rhizobacteria associated to Vitis vinifera and their effect on the control of Xiphinema index, Meloidogyne ethiopica and Vitis growth
Abstract : Plant-parasitic nematodes are one of the most important pests affecting the growth of vineyards due to the destruction of new roots. Several species are associated with this problem, the most important being the ectoparasite Xiphinema index and the endoparasite Meloidogyne ethiopica. READ MORE

17. Host-Parasite Interactions in Natural Populations
Abstract : Parasitism is one of the most common ways of living and it has arised in many taxa. Parasites feed and live inside or on their hosts resulting in both long and short term consequences for the host. This thesis is exploring the phenotypic and genotypic effects of animals living with parasitic infections. READ MORE

18. Ecology of pollinators, pests and natural enemies in agricultural landscapes : ensuring a sustainable supply of clover seeds
Abstract : The human population and its food consumption continues to grow and the environmental impact of meeting future food demands depends on how we expand the food supply. Already, agricultural intensification has led to biodiversity declines, which in turn can have direct and indirect effects on agricultural production. READ MORE

19. Ecology and management of crop pollination and pest control : insights from red clover seed production
Abstract : The agricultural landscape has gone through large changes to meet increasing demands for food. This has led to major biodiversity declines, while effects on ecosystem services that support agricultural productivity, such as pollination and pest control, remain less studied. READ MORE

20. Plant resistance ecology - the role of resistance in plant-insect mutualisms
Abstract : Global food security is largely dependent on the use of synthetic pesticides for pest control. This extensive reliance on pesticides, however, has promoted widespread loss of insect diversity; thereby jeopardizing the provision of insect ecosystem services like pollination and biological control.
