Habitat segregation by female humpback whales in Hawaiian waters: avoidance of males? (2013)
Journal Article
Craig, A. S., Herman, L. M., Pack, A. A., & Waterman, J. (2014). Habitat segregation by female humpback whales in Hawaiian waters: avoidance of males?. Behaviour, 151(5), 613-631. https://doi.org/10.1163/1568539x-00003151

Humpback whales congregate annually in low-latitude winter breeding and calving grounds. While on these grounds, females with a dependent calf (‘maternal females’) are sometimes closely attended by one or more male escorts. Using data collected from...

Summary
The relative importance of specialized and generalized plant-pollinator relationships is contentious, yet analyses usually avoid direct measures of pollinator quality (effectiveness), citing difficulties in collecting such data in the field...

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?.
