OK, I’m off to INTECOL, hope to see you there! I haven’t uploaded my slides, but I have put the preprint of the study I’ll be presenting on the arXiv. Hartig, F.; Münkemüller, T.; Johst, K. & Dieckmann, U. (under review) On the sympatric evolution of coexistence by relative nonlinearity of competition arXiv:1308.3114. If this…
A comment on a recent post gave me the motivation to try out the new EasyABC package for R, developed by Franck Jabot, Thierry Faure, Nicolas Dumoulin and maintained by Nicolas Dumoulin. Approximate Bayesian Computation (ABC) is a relatively new method that allows treating any stochastic model (IBM, stochastic population model, …) in a statistical…
Evolution is a tricky thing – and so is inferring general theory from simplified model results. This is proven once again in a new study by Leithen K. M’Gonigle with Ulf Dieckmann as senior author, which challenges the wide held belief that sexual selection alone cannot stabilize coexistence in the absence of ecological differentiation when…
IMPORTANT UPDATE 16.4.: Since this was posted, Jan Thiele made some improvements to RNetLogo, and there will be a new version out soon with improved performance for large data transfers. Jan also noted that the new NetLogo version 5.0 is considerably faster than the 4.x line which was used to create the figures below, so…
Our new review on statistical inference for stochastic simulation models is now available at Ecology Letters. The paper discusses how approximate likelihood functions can be generated from stochastic simulations. Such simulation-based likelihood approximations are a very general and powerful tool because they allow us to apply statistical methods to a large class of models such…
