Evolution of swimming performance in fish

Fish are remarkably diverse in their number of species, morphology and mechanisms of propulsion. Our lab is interested in how all of these factors affect the swimming abilities of fish, do we see consistent patterns of performance in relation to morphological or ecological variation? How does convergence in locomotor gait influence swimming abilities? In collaboration with Jay Nelson, we have the capability to measure any aspect of fish swimming, escape response, sprint speed, critical swimming speed, cost of transport, energy use and kinematics. My previous research examined the repeatability of swimming performance (Oufiero and Garland 2009), variation along ecological gradients (Oufiero et al. 2011), and the locomotor costs associated with the sexually selected sword among Xiphophorus (Oufiero et al. 2012, 2014a, 2014b), Update Fall 2020: these projects are on hold as we prepare to move to the new Science Building, including state of the art aquatic facilities:

  1. Examining the swimming energetic costs of male swordtail fish
  2. Swimming performance among gymnotiform swimmers
  3. Establishing a comparable metric for swimming energetics and agility/maneuverability
  4. Effects of urbanization on swimming performance and physiology (with Jay Nelson)
