Nocturnal dinosaurs, again: the benefits of discriminant analysis in quantitative paleobiology
More on nocturnal dinosaurs, or, importantly, on our quantitative approach to infer ecology and behavior in fossil vertebrates. Hall et al.’s technical comment provided us with the opportunity to further explain the benefits of our approach. Schmitz, L. & R. … Continue reading
The eyes of reef fishes
Peter and I recently published a paper in BMC Evolutionary Biology and today the final HTML and PDF versions have become available. BMC is an open access journal, so everyone can read the paper: Schmitz, L. & P.C. Wainwright (2011). … Continue reading
An optical illusion?
