Effects of anthropogenic land-use on communication and health of wild bees

Pollination is the most important ecosystem service bees carry out for human benefits. Honeybees, bumblebees and solitary bees, which are the most important actors in pollination, are threatened by a lot of different factors these days. Several studies named limited food and habitat resources, agrochemicals, pathogens and parasites as well as climate change as main drivers of declining species richness and abundance.

My PhD thesis focusses on anthropogenic land-use intensity and the effects on health and communication of different species of wild bees. I want to investigate the effects of single land-use stressors and their effects on communication and health status in wild bees.
