Journal Article
Hill, M. J., Biggs, J., Thornhill, I., Briers, R. A., Gledhill, D. G., White, J. C., …Hassall, C. (2017)
Urban ponds as an aquatic biodiversity resource in modified landscapes. Global Change Biology, 23(3), 986-999. https://doi.org/10.1111/gcb.13401
Urbanization is a global process contributing to the loss and fragmentation of natural habitats. Many studies have focused on the biological response of terrestrial taxa and h...

Size-assortative pairing and discrimination of potential mates by humpback whales in the Hawaiian breeding grounds

Journal Article
Pack, A. A., Herman, L. M., Spitz, S. S., Craig, A. S., Hakala, S., Deakos, M. H., …Lowe, C. (2012)
Size-assortative pairing and discrimination of potential mates by humpback whales in the Hawaiian breeding grounds. Animal Behaviour, 84(4), 983-993. https://doi.org/10.1016/j.anbehav.2012.07.024
Assortative pairing, and its relation to mate choice, has rarely been documented in mammals. Using data collected from 1998-2007, we investigated size-assortative pairing as i...

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...

The thin(ning) green line? Investigating changes in Kenya's seagrass coverage

Journal Article
Harcourt, W. D., Briers, R. A., & Huxham, M. (2018)
The thin(ning) green line? Investigating changes in Kenya's seagrass coverage. Biology Letters, 14(11), https://doi.org/10.1098/rsbl.2018.0227
Knowledge of seagrass distribution is limited to a few well-studied sites and poor where resourcesare scant (e.g. Africa), hence global estimates of seagrass carbon storage ar...

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 ...

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...

Developing an empirical approach to optimal camera-trap deployment at mammal resting sites: evidence from a longitudinal study of an otter Lutra lutra holt

Journal Article
Findlay, M., Briers, R., Diamond, N., & White, P. (2017)
Developing an empirical approach to optimal camera-trap deployment at mammal resting sites: evidence from a longitudinal study of an otter Lutra lutra holt. European journal of wildlife research, 63(6),
The study of nocturnal mammals relies on indirect evidence or invasive methods involving capture and tagging of individuals. Indirect methods are prone to error, while capture...
