Effects of land-use intensity on pollination services and pollinator health
Pollinators provide an essential ecosystem service and are currently threatened by a variety of anthropogenic influences and changing environmental conditions. In intensively used agricultural areas, pollinators suffer from resource limitation, exposure to pesticides as well as habitat loss and fragmentation, why land-use intensity represents a major threat for pollinators in such landscapes. These stressors can affect pollinator health (e.g. increased pathogen loads, developmental changes), which may in return result in a loss of pollination services (e.g. decreased foraging activity).
My PhD aims to help understanding how to preserve pollination services and ecosystem functioning in land-use intensive areas by disentangling the links between land-use intensity, pollinator health and pollination services. To achieve this, I will investigate pollinator health indicators and foraging behaviour of two pollinator species (Bombus lapidarius & Episyrphus balteatus) in agricultural landscapes.
