Scientists keep warning, I stopped signing

A guest post by Carsten Dormann (Uni Freiburg) / @CarstenDormann. Cover picture by Takver via Wikimedia Commons. BioScience has just published the latest installment of “Scientists’ Warnings“. There have been two previous such Warnings, the latest organised by the same authors in 2017. Quite a few scientists have signed this Warning. I chose not to,…

Yes, statistical errors are slowing down scientific progress!

Over at dynamic ecology,  Jeremy Fox argues that Technical statistical mistakes are overrated; ecologists (especially students) worry too much about them. Individually and collectively, technical statistical mistakes hardly ever appreciably slow the progress of entire subfields or sub-subfields. And fixing them rarely meaningfully accelerates progress. continuing with Don’t agree? Try this exercise: name the most…

Biotic interactions and jSDM – report from a workshop at the Ecology Across Borders conference in Ghent, Dez 2017

Originally posted on AK Computational Ecology:
This guest post by Carsten F. Dormann, with inputs from Casper Kraan and the panel (see below) summarises the results from the short workshop “Biotic interactions and joint species distribution models” at the Ecology Across Borders BES/GfÖ/NEVECOL/EEF-meeting 2017 in Ghent, Belgium. The purpose of this event was to exchange thoughts and…

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.…

3-year PostDoc Position on Connecting Forest Models, Data and Diversity Effects in Freiburg

NOTE: the position has been filled! We still seek applicants for a 3-yr PostDoc project that combines process-based forest models, Bayesian parameter estimation and ecologically the question of what processes cause diversity effects in temperate forests. A pdf with details of the call can be downloaded here. The position is available immediately. A first consideration…

Notes from France

I’ve just returned from two weeks in France, the first week on the International Statistical Ecology Conference 2014 in Montpellier, and the second at the Laboratoire d’Écologie Alpine (LECA) in Grenoble, visiting the groups of Wilfried Thuiller and Sébastien Lavergne, which was both great. Some impressions from the ISEC: First of all, my compliments to…
