Flower‐visitor and pollen‐load data provide complementary insight into species and individual network roles (2024)
Journal Article
Cirtwill, A. R., Wirta, H., Kaartinen, R., Ballantyne, G., Stone, G. N., Cunnold, H., Tiusanen, M., & Roslin, T. (2024). Flower‐visitor and pollen‐load data provide complementary insight into species and individual network roles. Oikos, 2024(4), Article e10301. https://doi.org/10.1111/oik.10301

Most animal pollination results from plant–insect interactions, but how we perceive these interactions may differ with the sampling method adopted. The two most common methods are observations of visits by pollinators to plants and observations of po...

Stable pollination service in a generalist High Arctic community despite the warming climate (2022)
Journal Article
Cirtwill, A., Kaartinen, R., Rasmussen, C., Redr, D., Wirta, H., Olesen, J., Tiusanen, M., Ballantyne, G., Cunnold, H., Stone, G., Martin Schmidt, N., & Roslin, T. (2023). Stable pollination service in a generalist High Arctic community despite the warming climate. Ecological monographs, 93(1), Article e1551. https://doi.org/10.1002/ecm.1551

Insects provide key pollination services in most terrestrial biomes, but this service depends on a multi-step interaction between insect and plant. An insect needs to visit a flower, receive pollen from the anthers, move to another conspecific flower...

We are currently seeing an expansion of pollinator-dependent crops in many parts of the world, but also growing evidence for pollinator population declines and loss of pollinator habitat. Climate change and population growth will place additional dem... Read More about Insect Pollination and Sustainable Agriculture in Sub-Saharan Africa.

Estimating pollinator performance of visitors to the self-incompatible crop-plant Brassica rapa by single visit deposition and pollen germination: a comparison of methods (2017)
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 loads, and single visit deposition (SVD) are all useful proxies for perfor...

Pollinator importance networks illustrate the crucial value of bees in a highly speciose plant community (2017)
Journal Article

Accurate predictions of pollination service delivery require a comprehensive understanding of the interactions between plants and flower visitors. To improve measurements of pollinator performance underlying such predictions, we surveyed visitation f...

Floral visitors and ant scent marks: noticed but not used? (2012)
Journal Article

1. Bee behaviour when visiting flowers is mediated by diverse chemical cues and signals, from the flower itself and from previous visitors to the flower. Flowers recently visited by bees and hoverflies may be rejected for a period of time by subseque... Read More about Floral visitors and ant scent marks: noticed but not used?.

Nectar Theft and Floral Ant-Repellence: A Link between Nectar Volume and Ant-Repellent Traits? (2012)
Journal Article
Ballantyne, G., & Willmer, P. (2012). Nectar Theft and Floral Ant-Repellence: A Link between Nectar Volume and Ant-Repellent Traits?. PLOS ONE, 7(8), Article e43869. https://doi.org/10.1371/journal.pone.0043869

As flower visitors, ants rarely benefit a plant. They are poor pollinators, and can also disrupt pollination by deterring other flower visitors, or by stealing nectar. Some plant species therefore possess floral ant-repelling traits. But why do parti... Read More about Nectar Theft and Floral Ant-Repellence: A Link between Nectar Volume and Ant-Repellent Traits?.
