Demography and Molecular Ecology of the Solitary Halictid Lasioglossum Zonulum: with Observations on Lasioglossum Leucozonium
Demography and molecular ecology of the solitary halictid Lasioglossum zonulum: With observations on Lasioglossum leucozonium Alex N. M. Proulx, M.Sc. Biological Sciences (Ecology and Evolution) Submitted in partial fulfillment of the requirements for the degree of Master of Science Faculty of Mathematics and Science, Brock University St. Catharines, Ontario © 2020 Thesis Abstract Halictid bees are excellent models for questions of both evolutionary biology and molecular ecology. While the majority of Halictid species are solitary and many are native to North America, neither solitary nor native bees have been extensively studied in terms of their population genetics. This thesis studies the social behaviour, demographic patterns and molecular ecology of the solitary Holarctic sweat bee Lasioglossum zonulum, with comparisons to its well-studied sister species Lasioglossum leucozonium. I show that L. zonulum is bivoltine in the Niagara region of southern Ontario but is univoltine in a more northern region of southern Alberta. Measurements of size, wear and ovarian development of collected females revealed that Brood 1 offspring are not altruistic workers and L. zonulum is solitary. A large proportion of foundresses were also found foraging with well-developed ovaries along with their daughters, meaning L. zonulum is solitary and partially-bivoltine in the Niagara region. L. zonulum being solitary and univoltine in Calgary suggests that it is a demographically polymorphic and not socially polymorphic. Thus, L. zonulum represents a transitional evolutionary state between solitary and eusocial behaviour in bees. I demonstrate that Lasioglossum zonulum was introduced to North America at least once from Europe in the last 500 years, with multiple introductions probable. -

Gardiner * ID Department of Entomology, The Ohio State University, 2021 Coffey Road, Columbus, OH 43210, USA; [email protected] (F.S.S.); [email protected] (S.P.P.) * Correspondence: [email protected]; Tel.: +1-330-601-6628 Received: 1 May 2018; Accepted: 5 June 2018; Published: 8 June 2018 Abstract: We investigated the relative importance of vacant lot and urban farm habitat features and their surrounding landscape context on bee community richness, abundance, composition, and resource use patterns. Three years of pan trap collections from 16 sites yielded a rich assemblage of bees from vacant lots and urban farms, with 98 species documented. We collected a greater bee abundance from vacant lots, and the two forms of greenspace supported significantly different bee communities. Plant–pollinator networks constructed from floral visitation observations revealed that, while the average number of bees utilizing available resources, niche breadth, and niche overlap were similar, the composition of floral resources and common foragers varied by habitat type. Finally, we found that the proportion of impervious surface and number of greenspace patches in the surrounding landscape strongly influenced bee assemblages. At a local scale (100 m radius), patch isolation appeared to limit colonization of vacant lots and urban farms. However, at a larger landscape scale (1000 m radius), increasing urbanization resulted in a greater concentration of bees utilizing vacant lots and urban farms, illustrating that maintaining greenspaces provides important habitat, even within highly developed landscapes. -

Changes in Composition and Structure of a Wild Bee Community and Plant- Pollinator Interactions in South-Central Ontario Over a Forty-Nine Year Period
Changes in composition and structure of a wild bee community and plant- pollinator interactions in South-Central Ontario over a forty-nine year period by Claire Rubens A thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Environmental Sciences Guelph, Ontario, Canada © Claire Rubens, September 2019 ABSTRACT CHANGES IN COMPOSITION AND STRUCTURE OF A WILD BEE COMMUNITY AND PLANT-POLLINATOR INTERACTIONS IN SOUTH-CENTRAL ONTARIO OVER A FORTY-NINE YEAR PERIOD Claire Rubens Advisor: University of Guelph, 2019 Professor Nigel E. Raine Wild pollinators provide important ecosystem services for both agricultural and natural ecosystems. While there is evidence of global pollinator declines, more long-term studies are needed to assess population trends, and the potential impacts of environmental stress factors such as land-use intensification and climate change. This is the first study to examine long-term changes in a wild bee community in Canada. Wild bee abundance, species richness, diversity and evenness were compared across three sampling periods (1968-1969, 2002-03, and 2016-17) in Caledon, Ontario over 49 years. Despite decreases in wild bee abundance since 2002-03, the diversity, evenness and richness increased over time. Extensive restructuring (including loss and frequency changes) of plant-pollinator interactions from 2002-03 to 2016-17 appeared not to affect network resilience. While local trends in land-use patterns did not predict changes in this wild bee community, climatic changes in temperature and snowfall correlated with wild bee abundance at the site. iii ACKNOWLEDGEMENTS I would like to thank my advisor Dr. -
