A Bug Eat Bug World : Does Urbanization Decrease Survivorship Of Pollinators., Amy L. Cherry
College of Arts & Sciences Senior Honors Theses
Human impact on the environment is responsible for the sixth mass extinction on Earth as well as rapid population declines in many taxa. Land use change, via increasing urbanization and intensity of agricultural practices, is the most important aspect of human impact on the environment, and it is associated with population decline and extinction in several taxa, but especially in pollinator species. Pollinators, which are essential for crop production, are experiencing declines as a result of the loss of habitat and host plants associated with urbanization. Urbanization negatively affects pollinators, but in the wake of lost naturalized habitat, some researchers …

Flower Visitation In Relation To Pollen And Nectar Nutrition: Implications For Pollinator Habitat And Conservation, Megan E. Leach
Electronic Theses and Dissertations
Pollination of both wild and crop plants is at a crossroads; honey bee populations are experiencing losses at a higher rate than ever before, and some native bee species are declining in abundance to the point of being listed as endangered species. A few examples of these threats include pesticide exposure, habitat loss, and climate change. In response to bee population declines, conservation efforts have been initiated to increase habitat quality for bees by planting pollinator reservoirs or gardens. Plants provide nutrition to bees in the form of pollen and nectar. Several studies have shown links between higher nutritional quality …

Theses and Dissertations--Entomology
Public awareness of declining pollinator populations has increased interest in creating “bee–friendly” urban landscapes. I quantified bee visitation and assemblages of 72 species of flowering woody plants common in urban landscapes. I found strong plant species effects and variation in seasonal activity of particular bee taxa but no overall differences in bee visitation or genus diversity between native versus nonnative species or trees versus shrubs. Analysis of pollen from a subset of these plants revealed small but statistically significant differences in total and essential amino acids between native and nonnative species and trees and shrubs, although each group had species …
