The first half of 2016 in review

4 August 2016
It’s always good to pause and take stock of what has happened. I usually do this personally, but figured I could also post about it as news to catch up on my backlog of things that have happened.

In February, our paper on the effects of plant compensatory regrowth on herbivore population dynamics was published in The American Naturalist. Long story short, plant compensatory regrowth, by themselves, can cause herbivore populations to cycle and can interact with plant resistance to produce non-intuitive effects on herbivore dynamics.

QPot v1.1 The R Package for SDEs

19 April 2016
We’ve released QPot v1.1 into the wild!

QPot, the R software package for analyzing stochastic differential equations using the quasipotential, has been updated to version 1.1. The help files have been updated. The function Model2String has been updated to replace parameter names with parameter values for both simple strings as well as the function format used by deSolve.
QPot is available on the Comprehensive R Archive Network (CRAN) at Our paper demonstrating applications of QPot has been resubmitted to the R Journal. A preprint version can be downloaded at

QPot The R Package for SDEs

23 October 2015
We’ve released QPot into the wild!

From Ben’s press release:
Researchers in Dr. Karen Abbott’s theoretical ecology lab in the Department of Biology at Case Western Reserve University have recently released a software package that will help scientists studying stochastic dynamical systems. The package, written for the programming language R, is called QPot (short for quasi-potential, which is one of the its primary analytic tools). Professor Karen Abbott’s lab, which includes research associates Christopher Moore, Christopher Stieha, and Ben Nolting, collaborated with Professor Maria Cameron from the University of Maryland to create QPot, which they hope will be useful to researchers in a wide variety of scientific disciplines, ranging from ecology to physics. QPot is available on the Comprehensive R Archive Network (CRAN) at A paper demonstrating applications of QPot has been submitted to the R Journal and can be downloaded at (to be filled shortly).

A test of new posts

A simple post to make sure that my website posts only the three newest posts.
Nothing more, nothing less.

working on my website

My website is a combination of HTML and Jekyll served up by Github Pages.
Because I wanted to blog like a hacker.

I found these two sites useful for learning to build a website with Jekyll:

Jekyll by example by Andrew Munsell

CNAME leads to infinite loop

I’m trying to get my website to work with redirects. So far, I have the redirect from to my github site. I had CNAME set as, which seemed to have caused an infinite loop as the website bounced from to github back to I need to be more systematic about this AND account for the lag between update and DNS resolution.
