Structure, Control, And Communication Of Collective Animal Behavior In Dynamic Environments, Ivan Ignacio Rodriguez-Pinto Jun 2020

Structure, Control, And Communication Of Collective Animal Behavior In Dynamic Environments, Ivan Ignacio Rodriguez-Pinto

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 …


The Effects Of Copper Exposure On Fish Locomotion And Predator-Prey Interactions, Tiffany N. Yanez Dec 2018

The Effects Of Copper Exposure On Fish Locomotion And Predator-Prey Interactions, Tiffany N. Yanez

FIU Electronic Theses and Dissertations

This study determined the effects of the copper water quality criterion (WQC) by the EPA on [1] swimming performance and [2] predator-prey interactions of the Sailfin Molly, across a salinity gradient. Fish acclimated to FW (0 ppt) and 8-ppt saltwater were exposed to 11.3 and 8.44 µg/L Cu for 96 h, respectively. At the end of the exposures, fish swimming performance was determined by using the critical swimming speed, Ucrit, the speed at which a fish cannot longer maintain position in the water column. Ucritwas then measured again after a 4-week depuration period to determine if …
