What’s wrong with null models?

A guest post by Carsten F. Dormann Over the last years, I have been using null models more often than I liked. I had to, when there was no other way to figure out if an ecological pattern was unexpected, or trivial. Inspired by some recent (and also some older) posts, I thought I might throw around…

An illustration of a intransitive relationship between species A,B,C

Why my money is still on transitivity in plant communities

Guest post by Carsten F. Dormann In his book “The Signal and the Noise”, Nate Silvers likened competing scientific hypotheses to betting. If you think that your hypothesis H1 is correct, rather than H2, you should be willing to put money on it, with odds reflecting your belief in H1 vs H2. This post collects…

All models are wrong, but which are useful for understanding the effect of nestedness on plant-pollinator dynamics?

A guest post by Gita Benadi and Jochen Fründ Mutualistic networks have become an increasingly popular way of describing mutually beneficial interactions between species-rich communities, for example those between plants and their pollinators. Besides offering a nice method of visualizing these interactions, networks are also used to make inferences about the relationship between interaction structure…

Training school and workshop on calibration and validation of dynamic vegetation models in France

Two events I’m involved in that may be interesting for people that work on connecting process-based vegetation models to data. Both are organized through CA 1304 PROFOUND, and fully funded by COST: There will be a training school on Bayesian calibration, forecasting and multi-model predictions of process-based vegetation models in Rencurel / Grenoble, France, 12.-16.…
