Outline of research

Dr. Fields is a zooplankton ecologist. The Fields’ laboratory studies the role of zooplankton (particularly copepods) in transferring organic matter through the food web and in mediating bio-geochemical cycling in the oceans.  Our approach is to understand how the mechanisms that occur at the level of the individual animal drive regional and global scale distribution patterns in zooplankton.  This work incorporates general data of zooplankton ecology (classical grazing experiments, egg production and developmental rates) as well as data from small-scale fluid mechanics, neurophysiology and animal behavior.

Ongoing Research

Sensory ecology and neurophysiology of marine zooplankton. We study the characteristics of the setal motion (and the required fluid motion and force) that gives rise to the neurophysiological response in copepod mechanoreceptors. The work aims to how copepods differentiate among the myriad of fluid signals in their environment and how copepods code these complex signals in a rapid yet highly accurate manner.

Impact of global climate change on zooplankton populations. We study effects of natural and anthropogenic changes on the energy transfer between trophic levels. Specifically we focus on grazing, respiration, reproduction and fecal pellet production rates of copepods under different climate scenarios.
