The potential of restored landfill sites to support pollinating insects
… potential of restored landfill sites to support pollinating insects and how flower-insect interactions can be used in determining successful restoration. These are important attributes of ecosystem function. Standard belt transects were used to record flowering insect pollinated plants and …

Systems to Attract and Feed Pollinators in Warm-Season Lawns
<p>Pollinating insects are responsible for the production of many agricultural crops and they require floral resources to fulfill their life-cycle. Ideally, pollinating insects will encounter a diversity of floral resources across their entire season of activity, and those floral resources can …

Planning for Pollinators, Encouraging Biodiversity for Agriculture Resiliency
… or extinct. Among these declining species are pollinating insects such as <em>Aphis mellifera </em>(honeybee) and other native species. This is due to a phenomenon known as colony collapse disorder (CCD) and other native bees. The decline indicates that the future habitability of earth may be …

Multiple dimensions of floral rewards drive pollinator behavior and pollen movement
… plants produce a diversity of rewards to attract pollinating insects. Most commonly these are nutritional rewards; either pollen (primarily protein and lipids) and/or nectar (primarily carbohydrates) in varying combinations and qualities. This reward strategy varies inter- and intraspecifically, …

Pheromones, nectar, and computer vision: investigating large-scale patterns of chemodiversity.
… acts primarily to manipulate high quality pollinating insects, with little impact on non-pollinating insects. Finally, chapter 4 moves from interrogations of chemical diversity in plants and insects to discuss methods of monitoring insect biodiversity as a whole. Here I developed a computer …

Plant communities along Irish roads: the impact of humans and potential to improve biodiversity
… in both species richness and resources for pollinating insects than a traditional landscape treatment approach. The seed bank of the road verge contained more species than that of the adjacent field. A number of species were only found in the overall seed bank and were not recorded in any of …

Toxicity assessment of pesticides and biopesticides on wild and managed bees (Hymenoptera, Apoidea), and richness evaluation in mediterranean and tropical agroecosystems
… (Hymenoptera, Apoidea) are the main pollinator insects for wild and cultivated plants, being of crucial environmental and economic importance. Their global decline, driven by anthropogenic factors, including the use of synthetic pesticides, is an alarming concern. Biopesticides can be a viable …

Effects of temperature and pollinator availability on plant reproductive success in the Indiana spring ephemeral community
… is a key driver of phenology in both plants and insects, and even small changes in temperature can impact the reproductive success of insect-pollinated plants by influencing access to pollinator services. While it is well-established that temperature variation directly impacts the flowering …

The Evolution of Male Form and Function in Nightshade Flowers

Behavioural, microhabitat, and phylogenetic dimensions of intrasexual contest competition in combatant monkey beetles (Scarabaeidae: Hopliini)
… and phenotypically diverse group of pollinating insects in the Greater Cape Floristic Region (GCFR) that shows a high degree of sexual dimorphism and mating behaviour driven by male-male competition. I build on previous observations of hind leg use in intrasexual male-male contest for …

Sensory Ecology of Foraging in Bumblebees
Pollinating insects exhibit a complex behavior while foraging for nectar and pollen. Many studies have focused on ultimate mechanisms of this behavior, however, the sensory-perceptual processes that constrain such behavior have rarely been considered. In the present study I used bumblebees (Bombus …

Assessing the relationships between pollinator-friendly plantings and birds, bats and white-tailed deer on farms in the Coastal Plain of Virginia and Maryland
… to improve ecosystem services provided by pollinating insects on farmland. However, the potential ecosystem service benefits, or even disservices, of pollinator-friendly plantings relative to wildlife, such as resident, migratory, and nesting birds (e.g., wild turkey (Meleagris gallopavo)), …
