Ocypodid crabs inhabit intertidal sandy/muddy flats of tropical and sub-tropical mangroves. Iran has three species of the genus Austruca. In contrast to A. sindensis and A. la...

Structural and functional indices show similar performance in marine ecosystem quality assessment

Journal Article
Culhane, F. E., Briers, R. A., Tett, P., & Fernandes, T. F. (2014)
Structural and functional indices show similar performance in marine ecosystem quality assessment. Ecological Indicators, 43, 271-280. https://doi.org/10.1016/j.ecolind.2014.03.009
Reliable ecosystem quality assessment of marine environments is increasingly important due to mounting pressures attributable to human activities. Biotic indices are widely us...

Framework for understanding marine ecosystem health

Journal Article
Tett, P., Gowen, R., Painting, S., Elliott, M., Forster, R., Mills, D., …Wilkinson, M. (2013)
Framework for understanding marine ecosystem health. Marine Ecology Progress Series, 494, 1-27. https://doi.org/10.3354/meps10539
Although the terms ‘health’ and ‘healthy’ are often applied to marine ecosystems and communicate information about holistic condition (e.g. as required by the Ecosystem Approa...

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...

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...
