In meta-analysis, study participants are nested within studies, leading to a multilevel data
structure. The traditional random effects model can be considered as a model with a random …

Urbanisation can affect mating opportunities and thereby alter inter‐and intra‐sexual
selection pressures on sexual traits. Biotic and abiotic urban conditions can influence an …

Animals often need to signal to attract mates and behavioural signalling may impose
substantial energetic and fitness costs to signallers. Consequently, individuals often …

Meta‐analyses in ecology and evolution require special attention due to certain study
characteristics in these fields. First, the primary articles in these fields usually report results …

Although examples of successful applications of behavioral ecology research to policy and
management exist, knowledge generated from such research is in many cases under …

Interspecific comparisons of endocrine data are useful for drawing broad conclusions
concerning the role of ecological variables in the evolution of physiological pathways …

To examine whether sexually selected traits are particularly sensitive bioindicators of
environmental toxicants, we assessed the effects of exposure to environmentally relevant …

Short‐term elevations in circulating stress hormones (glucocorticoids) often mediate
reduced investment in reproductive behaviour in favour of self‐maintenance and survival …

Primates are the most colourful members of the Mammalian clade. In vervet monkeys
(Chlorocebus pygerythrus), males are characterized by their red penis and blue scrotum …

We review work relating glucocorticoids (GCs), male sexual signals, and mate choice by
females to understand the potential for GCs to modulate the expression of sexually selected …
