Four ways in which data-free papers on animal personality fail to be impactful

open access: yesFrontiers in Ecology and Evolution, 2015
The literature on animal personality is dominated by papers lacking any data. These papers, which we will call ‘data-free’ papers, are cited and recognized twice as much as comparable empirical studies. In this data-free paper, we highlight 4 common data-

Drivers of flea abundance in wild rodents across local and regional scales in the Chihuahuan Desert, northwestern Mexico

open access: yesEcosphere, 2022
The broad distribution of macroparasites and their thriving populations are matters of health and economic concern. Macroparasites cause damage both directly through their feeding habits, which impact host fitness, and indirectly through the transmission

Generalized Functional Additive Mixed Models

open access: yes, 2016
We propose a comprehensive framework for additive regression models for non-Gaussian functional responses, allowing for multiple (partially) nested or crossed functional random effects with flexible correlation structures for, e.g., spatial, temporal, or
