Plant-pollinator interaction networks in remnant and reconstructed Palouse Prairie in Eastern WA, USA
… is often focused on re-establishing native plant communities, without considering the larger ecological community, specifically pollinators, despite their being critical to native forb reproduction. Further, ecological restoration has the potential to mitigate global pollinator declines by …

Functional diversity and mowing regime of flower strips as tools to support pollinators and to suppress weeds
… field margins. These flower strips enable wild plant communities to thrive and provide food and shelter to associated fauna. It is often suggested that increasing plant functional diversity could be a tool to optimize ecosystem functioning and ecosystem service delivery, and it could thus be a …

Prairie dogs, plants, and pollinators: tri-trophic interactions affect plant-insect floral visitor webs in shortgrass steppe
… prairie dogs (Cynomys ludovicianus) altered pollinator habitat, specifically in terms of bare ground cover and floral resources, on northeastern Colorado's Pawnee National Grassland, in 2003 through 2005. I also measured changes in habitat utilization by insect floral visitors on and off …

Social and ecological dimensions of supporting wild pollinators in tropical smallholder farms
… influence the availability of habitat for wild pollinators in tropical smallholder farming landscapes. The dissertation consists of three data chapters from independent investigations, combining a global systematic review and meta-analysis with social and ecological fieldwork in western Kenya. …

Plant-flower visitor interactions in the Sacred Valley of Peru
The structural organisation of species-rich plant-pollinator networks is important to understanding their ecology and evolution and is essential for making informed conservation and restoration decisions. This thesis reports on a study located at different altitudes in nine tributary valleys of the …

THE ANTAGONISTIC AND MUTUALISTIC PLANT-INSECT INTERACTIONS OF PITCHER’S THISTLE (CIRSIUM PITCHERI [TORR. EX EAT.] TORR. & A. GRAY, ASTERACEAE), A FEDERALLY THREATENED GREAT LAKES DUNE AND COBBLE SHORE ENDEMIC PLANT
… used for integrated pest management of invasive plant species but it is not without risks to native plants. I researched the non-target impacts of the biological control agent, the seed head weevil Larinus planus (Coleoptera: Curculionidae) on the Great Lakes dune and cobble shore endemic …

The functional ecology of Eastern Rûens Shale Renosterveld
… I used litter traps to investigate the effect of plant litter type, season and habitat degradation on litter decomposition rates and Springtail (Collembola) community dynamics, respectively. Finally, in Chapter 5, I constructed three high-resolution plant-pollinator networks from sites with …

Influence of Forest Management on Bumblebee-Plant Networks and Community Compositions in Eastern Kentucky Forest Openings
… of terrestrial ecosystems are reliant on animal pollinators to facilitate plant reproduction. Yet the integrity of these pollination services is threatened by the declines of pollinators. Mounting evidence indicates landscape homogenization in agricultural, urban, and most notably in natural …
