Turbidity weakens selection for assortment in body size in groups (2015)
Journal Article
Kimbell, H. S., & Morrell, L. J. (2016). Turbidity weakens selection for assortment in body size in groups. Behavioral ecology, 27(2), 545-552. https://doi.org/10.1093/beheco/arv183

Prey animals commonly associate with similar-looking individuals to reduce predation risk, via a reduction in predator targeting accuracy (the confusion effect) and preferential targeting of distinct individuals (the oddity effect). These effects are... Read More about Turbidity weakens selection for assortment in body size in groups.

Handedness in fiddler crab fights (2015)
Journal Article
Perez, D. M., Heatwole, S. J., Morrell, L. J., & Backwell, P. R. Y. (2015). Handedness in fiddler crab fights. Animal behaviour, 110(December), 99-104. https://doi.org/10.1016/j.anbehav.2015.09.012

Asymmetric weapons are common in bilateral animals and, in some species, they can occur on either the left- or the right-hand side of the body (lateralization). Fiddler crabs (Uca spp, Decapoda: Ocypodidae) have an enlarged claw that is used in male–... Read More about Handedness in fiddler crab fights.

'Selfish herds' of guppies follow complex movement rules, but not when information is limited (2015)
Journal Article
Kimbell, H. S., & Morrell, L. J. (2015). 'Selfish herds' of guppies follow complex movement rules, but not when information is limited. Proceedings of the Royal Society B: Biological Sciences, 282(1816), 1-7. https://doi.org/10.1098/rspb.2015.1558

Under the threat of predation, animals can decrease their level of risk by moving towards other individuals to form compact groups. A significant body of theoretical work has proposed multiple movement rules, varying in complexity, which might underl...

© 2015 The Association for the Study of Animal Behaviour. Increasing turbidity (either sedimentary or organic) from anthropogenic sources has significant negative impacts on aquatic fauna, both directly and indirectly by disrupting behaviour. In part...
