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?.

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

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?.

Using stable isotopes to assess the distribution of reproduction by migratory and resident Salmo trutta within river systems: some complicating factors (2017)
Presentation / Conference Contribution
Briers, R., Campbell, R., Galt, K., Walters, M., & Holmes, J. (2015, October). Using stable isotopes to assess the distribution of reproduction by migratory and resident Salmo trutta within river systems: some complicating factors. Presented at Second International Sea Trout Symposium

Understanding the distribution of spawning resident and migratory trout in a river system is important for fishery management. In most cases this information is lacking or only partial, and mostly derived from surveys of breeding adults. Stable isoto...

Kin selection theory predicts that, where kin discrimination is possible, animals should typically act more favorably toward closer genetic relatives and direct aggression toward less closely related individuals. Contrary to this prediction, we prese... Read More about Explaining negative kin discrimination in a cooperative mammal society.

Kin selection theory predicts that animals should direct costly care where inclusive fitness gains are highest. Individuals may achieve this by directing care at closer relatives, yet evidence for such discrimination in vertebrates is equivocal. We i...

An unexpected journey: Diurnal movement into deeper waters by humpback whale (Megaptera novaeangliae) mother-calf pairs observed off Northwest Maui, Hawai’i. Poster presented at 22nd Biennial Conference on the Biology of Marine Mammals, Halifax, Nova Scotia, Canada

Recent studies of humpback whale habitat use in the Hawaiian breeding grounds have revealed that mother-calf pairs favor shallow waters to avoid harassment from male humpbacks. However, human activity in these same shallow waters may, in theory, exe...
