Here are a few sources that I ran into while researching, but I did not include in my annotated bibliography. Someone might find them useful:
Colesworthy, Rebecca. “‘The Perfect Hostess’: Mrs. Dalloway, Gift Exchange, and the End of Laissez-Faire.” Modernist Cultures, vol. 9, no. 2, Fall 2014, pp. 158-185.
Czarnecki, Kristin, and Carrie Roman, editors. Virginia Woolf and the Natural World: Selected Papers from the Twentieth Annual International Conference on Virginia Woolf. Georgetown University, 2010. (This one looks really interesting, but I haven’t been able to look over it because it just came through on the library exchange).
Tromanhauser, Vicki. “Mrs. Dalloway’s Animals and the Humanist Laboratory.” Twentieth Century Literature, vol. 58, no. 2, Summer 2012, pp. 187-212
Wiechert, Nora. “‘No Sense of Porportion’: Urban Green Space and Mental Health in Mrs. Dalloway.” Virginia Woolf Miscellany, vol. 78, Fall 2010, pp. 21-23.
