Fighting behaviour and the role of urinary signals in dominance assessment of Norway lobsters, Nephrops norvegicus (2008)
Journal Article
Breithaupt, T., Johnson, M., & Katoh, E. (2008). Fighting behaviour and the role of urinary signals in dominance assessment of Norway lobsters, Nephrops norvegicus. Behaviour, 145(10), 1447-1464. doi:10.1163/156853908785765917

Norway lobsters, Nephrops norvegicus, live on the bottom of the continental shelf where they construct and defend burrows. Little is known about their agonistic behaviour and potential mechanisms of dominance. This paper investigates fighting behavio...

Influence of individual state on swimming capacity and behaviour of Antarctic krill Euphausia superba (2008)
Journal Article
Johnson, M. L., & Tarling, G. A. (2008). Influence of individual state on swimming capacity and behaviour of Antarctic krill Euphausia superba. Marine ecology progress series, 366, 99-110. doi:10.3354/meps07533

Swarms of Antarctic krill are frequently biased towards certain body sizes, sexes, maturities and physiological states. However, the mechanisms causing such biases remain unclear, with some speculating on differential responses to chemical or visual...
