Journal Article
Willmer, P. G., Cunnold, H., & Ballantyne, G. (2017)
Insights from measuring pollen deposition: quantifying the pre-eminence of bees as flower visitors and effective pollinators. Arthropod-Plant Interactions, 11(3), 411-425. https://doi.org/10.1007/s11829-017-9528-2
Using our accumulated datasets from Kenyan savanna, Mediterranean garigue, UK gardens and heathland, involving 76 plants from 30 families, we present detailed data to quantify...

Flower‐visitor and pollen‐load data provide complementary insight into species and individual network roles

Journal Article
Cirtwill, A. R., Wirta, H., Kaartinen, R., Ballantyne, G., Stone, G. N., Cunnold, H., …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...

Resightings of humpback whales in Hawaiian waters over spans of 10-32 years: Site fidelity, sex ratios, calving rates, female demographics, and the dynamics of social and behavioral roles of individuals

Journal Article
Herman, L. M., Pack, A. A., Rose, K., Craig, A., Herman, E. Y. K., Hakala, S., & Milette, A. (2011)
Resightings of humpback whales in Hawaiian waters over spans of 10-32 years: Site fidelity, sex ratios, calving rates, female demographics, and the dynamics of social and behavioral roles of individuals. Marine Mammal Science, 27(4), 736-768. https://doi.org/10.1111/j.1748-7692.2010.00441.x
From a database of approximately 5,000 Hawaiian humpback whales identified photographically between 1976 and 2010, we extracted 71 males and 39 females having resighting spans...

Why flower visitation is a poor proxy for pollination: measuring single-visit pollen deposition, with implications for pollination networks and conservation

Journal Article
King, C., Ballantyne, G., & Willmer, P. G. (2013)
Why flower visitation is a poor proxy for pollination: measuring single-visit pollen deposition, with implications for pollination networks and conservation. Methods in Ecology and Evolution, 4(9), 811-818. https://doi.org/10.1111/2041-210x.12074
Summary The relative importance of specialized and generalized plant-pollinator relationships is contentious, yet analyses usually avoid direct measures of pollinator quality ...

Diel oxygen fluctuation drives the thermal response and metabolic performance of coastal marine ectotherms

Journal Article
Booth, J., Fusi, M., Giomi, F., Chapman, E., Diele, K., & McQuaid, C. (2021)
Diel oxygen fluctuation drives the thermal response and metabolic performance of coastal marine ectotherms. Proceedings of the Royal Society B: Biological Sciences, 288(1953), https://doi.org/10.1098/rspb.2021.1141
Coastal marine systems are characterized by high levels of primary production that result in diel oxygen fluctuations from undersaturation to supersaturation. Constant normoxi...

Floral visitors and ant scent marks: noticed but not used?

Journal Article
Ballantyne, G., & Willmer, P. (2012)
Floral visitors and ant scent marks: noticed but not used?. Ecological Entomology, 37(5), 402-409. https://doi.org/10.1111/j.1365-2311.2012.01378.x
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 visi...

Nectar Theft and Floral Ant-Repellence: A Link between Nectar Volume and Ant-Repellent Traits?

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), 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 pl...

Habitat preferences by individual humpback whale mothers in the Hawaiian breeding grounds vary with the age and size of their calves

Journal Article
Pack, A. A., Herman, L. M., Craig, A. S., Spitz, S. S., Waterman, J. O., Herman, E. Y., …Lowe, C. (2017)
