Journal Article
Fletcher, N., & Hardege, J. D. (2009). The cost of conflict: agonistic encounters influence responses to chemical signals in the European shore crab. Animal behaviour, 77(2), 357-361. https://doi.org/10.1016/j.anbehav.2008.10.007

The determination of an individual's behaviour often relies upon complex signals that convey messages about the environment it inhabits. In aquatic environments such signals take varied and conflicting forms including chemical cues indicating food or...

Development of behavioural and physiological assays to assess discrimination of male and female odours in crayfish, Pacifastacus leniusculus (2008)
Presentation / Conference Contribution
Berry, F. C., & Breithaupt, T. Development of behavioural and physiological assays to assess discrimination of male and female odours in crayfish, Pacifastacus leniusculus

Many aquatic organisms use chemical signals to coordinate courtship. However, relatively few water-borne pheromones have been identified. A key obstacle hindering progress in the purification of crustacean pheromones has been the development of relia...
