Model averaging in ecology: a review of Bayesian, information-theoretic and tactical approaches for predictive inference

This (co-)guest post by Carsten F. Dormann & Florian Hartig summarizes a comprehensive review on model averaging for predictive inference, just published in Ecological Monographs.

Mechanistic vs. phenomenological descriptions of nature

A few days ago, I came across a very interesting post on “Mechanistic models: what is the value of understanding?” by Amy Hurford on her Just Simple Enough: The Art of Mathematical Modelling blog. The post discusses the old, but for me still somewhat unresolved question of the relationship / definition / statistical treatment /…

Responses of Late Quaternary megafauna to climate and humans

In a proverbial “mammoth project”, Lorenzen and colleagues report in this weeks issue of Nature on the responses of six Late Quaternary megafauna herbivores (woolly rhinoceros, woolly mammoth, horse, reindeer/caribou, bison and musk ox) to climate and humans. The authors draw on various data sources, in particular species distribution models and ancient DNA, to “reconstruct…

Phylogenetics, models and evolution

I want to highlight two interesting papers coming out last week in the field of phylogenetics and evolution. The first is a paper by Nagalingum et al. who use fossil-calibrated molecular phylogenies to examine the diversification of cycads, and ancient lineage of woody plants. The cycad record dates back at least to the early Permian…
