Community heterogeneity of aquatic macroinvertebrates in urban ponds at a multi-city scale. Landscape Ecology, 33(3), 389-405. https://doi.org/10.1007/s10980-018-0608-1
Purpose
Urbanisation is a leading cause of biotic homogenisation in urban ecosystems. However, there has been little research examining the effect of urbanisation and biotic h...
Estimating pollinator performance of visitors to the self-incompatible crop-plant Brassica rapa by single visit deposition and pollen germination: a comparison of methods
Journal Article
Patchett, R., Ballantyne, G., & Willmer, P. (2017)
Estimating pollinator performance of visitors to the self-incompatible crop-plant Brassica rapa by single visit deposition and pollen germination: a comparison of methods. Journal of Pollination Ecology, 21(3), 78-85
Estimating the pollen-deposition effectiveness of flower visitors is fundamental to understanding their performance as pollinators. While estimates of visitation rates, pollen...

Nectar Theft and Floral Ant-Repellence: A Link between Nectar Volume and Ant-Repellent Traits?
Journal Article
Ballantyne, G., & Willmer, P. (2012)
