Analysis of Plankton Populations

I use numerical and analytical techniques to study the dynamics of various models of plankton food webs with and without resource fluctuations. Plankton are ideal organisms because they are very small, fast-reproducing organisms so they can easily be used in laboratory experiments to verify any results. We can study simple food webs to develop a better understanding of more complex food webs. T...

Adaptive and Demographic Responses of Plankton Populations to Environmental Change

Because of their large population sizes, short generation times, and clonal mode of propagation, microorganisms should often be the first members of a community to respond evolutionarily to temporal changes in the environment. Because the planktonic microbial community directly or indirectly influences all other members of aquatic ecosystems, it is useful to have a general theory for the magnit...

Bottom-up effects of climate on fish populations: data from the Continuous Plankton Recorder

The Continuous Plankton Recorder (CPR) dataset on fish larvae has an extensive spatio-temporal coverage that allows the responses of fish populations to past changes in climate variability, including abrupt changes such as regime shifts, to be investigated. The newly available dataset offers a unique opportunity to investigate long-term changes over decadal scales in the abundance and distribut...

Measuring the in situ carbon isotopic composition of distinct marine plankton populations sorted by flow cytometry

The carbon isotope ratio (dC value) of marine particulates is a potentially useful tracer for elucidating pathways of carbon flow in the marine environment. Different species of phytoplankton vary in fractionation vs. CO2 by up to 24& in laboratory cultures under varying nutrient and growth conditions, a signal that should propagate through the microbial food web. However, such contrasts have b...

Plankton lattices and the role of chaos in plankton patchiness.

Spatiotemporal and interspecies irregularities in planktonic populations have been widely observed. Much research into the drivers of such plankton patches has been initiated over the past few decades but only recently have the dynamics of the interacting patches themselves been considered. We take a coupled lattice approach to model continuous-in-time plankton patch dynamics, as opposed to the...
