Visual Ecology: Sensing The Social World, Elliott P. Steele
Dartmouth College Ph.D Dissertations
Social animals, and even solitary animals, must at different points in their life actively search for and locate conspecifics within their environment, using one or multiple senses. One sense in particular, vision, can provide some of the most spatially detailed and temporally rapid information about the environment. Yet, the surrounding environment can also severely challenge animals’ abilities to find fellow conspecifics. Furthermore, once an animal successfully locates conspecifics, it must then make key decisions about when and where to enter group formations, decisions which may strongly impact their access to socially-acquired resources. Even after an animal has positioned itself within …

Anticipation Induces Polarized Collective Motion In Attraction Based Models, Daniel Strömbom, Alice Antia
Northeast Journal of Complex Systems (NEJCS)
Moving animal groups are prime examples of natural complex systems. In most models of such systems each individual updates its heading based on the current positions and headings of its neighbors. However, recently, a number of models where the heading update instead is based on the future anticipated positions/headings of the neighbors have been published. Collectively these studies have established that including anticipation may have drastically different effects in different models. In particular, anticipation inhibits polarization in alignment-based models and in one alignment-free model, but promotes polarization in another alignment-free model. Indicating that our understanding of how anticipation affects the …

FIU Electronic Theses and Dissertations
Collective behavior in animal aggregations is highly complex and spans multiple spatial scales, across a wide range of environmental conditions. In socially active fish, aggregation into schools is a widespread adaptation that confers a variety of safety benefits. The emergent patterns exhibited by collectively behaving fish schools may be influenced by biotic (i.e. predation) or abiotic (i.e. habitat complexity, turbidity) factors in the local environment. Our knowledge of the ways and extent to which environment variability affects schooling behavior at the collective level is currently limited. In this dissertation, I investigated whether environmental factors influenced the collective behavior of fish …
