Focusing on data-rich studies, we also synthesize recent research on potential causes of population declines. There is evidence that habitat loss, changing climate, pathogen transmission, invasion of nonnative species, and pesticides, oper- ating individually and in combination, negatively impact bumble bee health, and that effects may depend on species and locality. -

Thesis Draft Rough
Wesleyan University The Honors College Plant-pollinator interactions across California grassland and coastal scrub vegetation types on San Bruno Mountain, San Mateo County by Miles Gordon Brooks Class of 2020 A thesis submitted to the faculty of Wesleyan University in partial fulfillment of the requirements for the Degree of Bachelor of Arts with Departmental Honors from the College of the Environment Middletown, Connecticut April, 2020 1 2 Abstract Animal pollination of plants is a crucial ecosystem service for maintaining biodiversity and ecosystem function, worldwide. High pollinator abundance and diversity can likewise improve the reproductive success of the plant community. Plant-pollinator interaction networks have the potential to identify dominant, specialist, and generalist pollinator species within a system, and their host plant counterparts. Understanding these relationships is paramount for buffering natural systems from biodiversity loss in a world where pollinator abundance continues to decline rapidly. San Bruno Mountain (SBM) in San Mateo County, California, is one of the last natural, open spaces in the urban landscape in the northern San Francisco Peninsula. I conducted a series of timed meanders and vegetation surveys at eight sample sites within SBM (four grassland and four coastal scrub sites) to identify plant species prevalence and pollinator species visitation of flowering plants. I employed a multivariate approach for investigating plant and pollinator species richness, plant and pollinator community composition, and trophic-level interactions across the SBM landscape, and I evaluated differences in these relationships between grassland and coastal scrub habitats. A total of 59 pollinator species and 135 plant species were inventoried over the course of the study. -

Box 1346 Ann Arbor, Ml 48106-1346 ABSTRACT The decline of British bumble bees has been attributed to the loss of their habitat through the intensification of agricultural practices. In the quest for information of use to bumble bee conservation the potential of our flower-rich cities has been overlooked. The overall aim of this study was to determine the status and foraging requirements of bumble bees in the urban environment provided by the city of London, U.K. My principal findings are as follows. Six common species and three rare species were identified. The greatest diversity of Bombus species was found in the east of London. Garden and wasteland habitats attracted the greatest abundance of workers and diversity of Bombus species. -
