Bees in Urban Landscapes: an Investigation of Habitat Utilization By
Bees in urban landscapes: An investigation of habitat utilization By Victoria Agatha Wojcik A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, & Management in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Joe R. McBride, Chair Professor Gregory S. Biging Professor Louise A. Mozingo Fall 2009 Bees in urban landscapes: An investigation of habitat utilization © 2009 by Victoria Agatha Wojcik ABSTRACT Bees in urban landscapes: An investigation of habitat utilization by Victoria Agatha Wojcik Doctor of Philosophy in Environmental Science, Policy, & Management University of California, Berkeley Professor Joe R. McBride, Chair Bees are one of the key groups of anthophilies that make use of the floral resources present within urban landscapes. The ecological patterns of bees in cities are under further investigation in this dissertation work in an effort to build knowledge capacity that can be applied to management and conservation. Seasonal occurrence patterns are common among bees and their floral resources in wildland habitats. To investigate the nature of these phenological interactions in cities, bee visitation to a constructed floral resource base in Berkeley, California was monitored in the first year of garden development. The constructed habitat was used by nearly one-third of the locally known bee species. Bees visiting this urban resource displayed distinct patterns of seasonality paralleling those of wildland bees, with some species exhibiting extended seasons. Differential bee visitation patterns are common between individual floral resources. The effective monitoring of bee populations requires an understanding of this variability. To investigate the patterns and trends in urban resource usage, the foraging of the community of bees visiting Tecoma stans resources in three tropical dry forest cities in Costa Rica was studied. -

Native Bees Are a Rich Natural Resource in Urban California Gardens

Lindon, and J. A. Brazille Texas AgriLife Research 2301 Experiment Station Road Bushland, TX 79012 2008 Report Introductory Notes The invertebrate survey in 2008 presented an interesting challenge. Extremely dry conditions prevailed throughout most of the adult activity period for the invertebrates and grass fires occurred several times throughout the summer. By visual assessment, plant resources were scarce compared to last year, with few green plants and almost no flowering plants. Eight habitats and nine sites continued to be sampled in 2008. The Ponderosa pine/ yellow indiangrass site was removed from the study after the low numbers of species and individuals collected there in 2007. All other sites from the 2007 survey were included in the 2008 survey. We also discontinued the collection of Coccinellidae in the 2008 survey, as only 98 individuals from four species were collected in 2007. Pitfall and malaise trapping were continued in the same way as the 2007 survey. Sweep net sampling was discontinued to allow time for Asilidae and Orthoptera timed surveys consisting of direct collection of individuals with a net. These surveys were conducted in the same way as the time constrained butterfly (Papilionidea and Hesperoidea) surveys, with 15-minute intervals for each taxanomic group. This was sucessful when individuals were present, but the dry summer made it difficult to assess the utility of these techniques because of overall low abundance of insects. -

Reproductive Biology of Larrea tridentata: A Preliminary Comparison Between Core Shrubland and Isolated Grassland Plants at the Sevilleta National Wildlife Refuge, New Mexico Rosemary L.

Reproductive Ecology of Astragalus Filipes, a Great Basin

Evans Major Professor Committee Member ________________________ _______________________ Eugene W. Schupp Byron R. Burnham Committee Member Dean of Graduate Studies UTAH STATE UNIVERSITY Logan, Utah 2010 ii ABSTRACT Reproductive Ecology of Astragalus filipes, a Great Basin Restoration Legume by Kristal M. Watrous, Master of Science Utah State University, 2010 Major Professor: Dr. James H. Cane Department: Biology Astragalus filipes Torrey ex. A. Gray (Fabaceae) is being studied and propagated for use in rangeland restoration projects throughout the Great Basin. Restoration forbs often require sufficient pollination services for seed production and persistence in restoration sites. Knowledge of a plant’s breeding biology is important in providing pollination for maximal seed set. Reproductive output from four manual pollination treatments (autogamy, geitonogamy, xenogamy, and distant xenogamy) was examined in a common garden. Pod set, seed set, and seed germination were quantified for each of the treatments. Seed set from four wild populations was compared to that of an openly visited common garden array. A. filipes was found to be self-compatible, but to benefit greatly from outcrossing. Less seed germinated from distantly outcrossed treatments than for any other treatment, indicating possible outbreeding depression. Common garden plants set less seed per pod than any wild population, possibly due to a depauperate pollinator guild in the common garden. iii Bees were surveyed at wild A. filipes populations to identify common pollinators. -

Hart Merriam elevation gradient along the San Francisco Peaks in northern Arizona. Elevational gradients can serve as natural proxies for climate change, replacing time with space as they span multiple vegetation zones over a short geographic distance. Describing the distribution of bee species along this elevation gradient will help predict how bee communities might respond to changing climate. To address this, we initiated an inventory associated with ecological studies on pollinators that documented bees on the San Francisco Peaks. -

Land Uses That Support Wild Bee (Hymenoptera: Apoidea: Anthophila) Communities Within an Agricultural Matrix
Land uses that support wild bee (Hymenoptera: Apoidea: Anthophila) communities within an agricultural matrix A DISSERTATION SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MINNESOTA BY Elaine Celeste Evans IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Dr. Marla Spivak December 2016 © Elaine Evans 2016 Acknowledgements Many people helped me successfully complete this project. Many years ago, my advisor, mentor, hero, and friend, Marla Spivak, saw potential in me and helped me to become an effective scientist and educator working to create a more bee-friendly world. I have benefitted immensely from her guidance and support. The Bee Lab team, both those that helped me directly in the field, and those that advised along the way through analysis and writing, have provided a dreamy workplace: Joel Gardner, Matt Smart, Renata Borba, Katie Lee, Gary Reuter, Becky Masterman, Judy Wu, Ian Lane, Morgan Carr- Markell. My committee helped guide me along the way and steer me in the right direction: Dan Cariveau (gold star for much advice on analysis), Diane Larson, Ralph Holzenthal, and Karen Oberauser. Cooperation with Chip Eullis and Jordan Neau at the USGS enabled detailed land use analysis. The bee taxonomists who helped me with bee identification were essential for the success of this project: Jason Gibbs, John Ascher, Sam Droege, Mike Arduser, and Karen Wright. My friends and family eased my burden with their enthusiasm for me to follow my passion and their understanding of my monomania. My husband Paul Metzger and my son August supported me in uncountable ways.
