Research Interests

 Research Interests


Generally, I am interested in dynamics of community and population structures and the functional consequences. More specifically, my research focusses on the impact of landscape structure and land-use intensity on pollinator communities and the services they provide. Here are my four Ts:

Taxonomy: Insects; mostly wild bees, hoverflies and solitary wasps.

Themes: landscape ecology; nature conservation; agri-environmental schemes.

Topics: pollination efficiency measures; plant-pollinator interactions; parasitoid-host interactions; mass-flowering crops (mainly oilseed rape).

Things I use: pan traps; sweep netting; optical and digital microscopy; flight cages; selfing bags; trap nests; pollen analysis; interaction networks, phytometer arrays.
