MS Graduate Research Assistantship

Many opportunities to join the Fish Ecology Lab are available to Graduate School candidates, Post-Doctoral Fellow candidates, Technicians, and Internship candidates.

I am currently seeking motivated and independent post-doctoral candidates who are interested in drafting a NSF post-doctoral fellowship proposal to work on fish population dynamics and climate change associated with the Toolik NSF LTER program, located in northern Alaska.

Post-doctoral Research Fellow Position

We seek a quantitative post-doctoral or post graduate (MS) research scientist to assist with three food web modeling experiments and a variety of other analytical projects for data sets describing two large and important lake ecosystems, Pyramid Lake, NV and Utah Lake, UT. In addition, the successful candidate will supervise the summer collection of fisheries field data on beautiful Bear Lake, UT/ID.

LapLanche, C. A. Elger, F, Santoul, G.P. Thiede, and P. Budy. In review. Forecasting the eradication success of an exotic fish from an alpine stream.

Submitted to Theoretical Ecology 21 April, 2017.

Density data are represented as an interactive 3D plot (for the complete period) which illustrates:
(1) brown trout is highly dominant downstream and
(2) completely absent upstream,
(3) the location of the switch in species dominance is fairly stable from 2001-2009,
(4) most density variation is of spatial nature, and (5) deviations of density to the locality mean are log-normally distributed.
We consequently assumed that the ecological system reached a steady state prior to 2009, see full text for more detail.
