Collective memory and spatial sorting in animal groups.
We present a self-organizing model of group formation in three-dimensional space, and use it to investigate the spatial dynamics of animal groups such as fish schools and bird flocks. We reveal theExpand

Effects of parasites on fish behaviour: a review and evolutionary perspective
Fish serve as hosts to a range of parasites that are taxonomically diverse and that exhibit a wide variety of life cycle strategies. Whereas many of these parasites are passed directly betweenExpand

Mortality risk of spatial positions in animal groups: The danger of being in the front
We modified Hamilton's (1971) selfish herd model by introducing directional movement to the prey groups and the predators. The consequences of this modification with regards to differential predationExpand
