Neal M. Williams and Claire Kremen. 2007. Resource distributions among habitats determine solitary bee offspring production in a mosaic landscape. Ecological Applications 17:910–921.

Appendix A. Proportions of different pollens collected by Osmia lignaria nesting at different site types within the agricultural-natural landscape.

TABLE A1. Proportions of different pollens collected by O. lignaria nesting at different site types within the agricultural-natural landscape. Site types indicated as C = conventional farm, O = organic farm, R = semi-natural riparian habitat Pollens are included only if they comprised at least 1% of one or more provisions during the season. Larger index values indicate greater proximity to semi-natural habitat and thus less isolation. Native plant species in bold exotic/ cultivated forms underlined.
