Reconciling ecogeographical rules: rainfall and temperature predict global colour variation in the largest bird radiation
Published in Ecology letters (01-04-2019)“…Ecogeographical rules that associate climate with organismal form and function can reveal patterns of climatic adaptation. Two rules link animal coloration…”

Fear of humans as apex predators has landscape‐scale impacts from mountain lions to mice
Published in Ecology letters (01-10-2019)“…Apex predators such as large carnivores can have cascading, landscape‐scale impacts across wildlife communities, which could result largely from the fear they…”

A global analysis of song frequency in passerines provides no support for the acoustic adaptation hypothesis but suggests a role for sexual selection
Published in Ecology letters (01-03-2021)“…Animals use acoustic signals for communication, implying that the properties of these signals can be under strong selection. The acoustic adaptation hypothesis…”

Density fluctuations represent a key process maintaining personality variation in a wild passerine bird
Published in Ecology letters (01-04-2016)“…Heritable personality variation is subject to fluctuating selection in many animal taxa; a major unresolved question is why this is the case. A parsimonious…”

It's not just what you have, but how you use it: solar‐positional and behavioural effects on hummingbird colour appearance during courtship
Published in Ecology letters (01-09-2018)“…Animals exhibit a diversity of colours that can play key roles in mating interactions. However, we presently lack an understanding of the relative importance…”

To follow or not? How animals in fusion–fission societies handle conflicting information during group decision‐making
Published in Ecology letters (01-08-2015)“…When group members possess differing information about the environment, they may disagree on the best movement decision. Such conflicts result in group…”
