Data from: Candidate gene polymorphisms for behavioural adaptations during urbanization in blackbirds

Jakob C. Mueller, Jesko Partecke, Ben J. Hatchwell, Kevin J. Gaston & Karl L. Evans
Successful urban colonisation by formerly rural species represents an ideal situation in which to study adaptation to novel environments. We address this issue using candidate genes for behavioural traits that are expected to play a role in such colonisation events. We identified and genotyped 16 polymorphisms in candidate genes for circadian rhythms, harm avoidance, and migratory and exploratory behaviour in 12 paired urban and rural populations of the blackbird Turdus merula across the Western Palearctic....

Data from: Nutrition during sexual maturation affects competitive ability but not reproductive productivity in burying beetles

Paul E. Hopwood, Allen J. Moore & Nick J. Royle
1. Food availability can be unpredictable. When food becomes more abundant following a period of low food availability, developing larvae or juveniles often allocate resources preferentially towards increasing growth. This has important long-term effects on adult phenotypes and longevity. Despite the importance of strategic resource allocation during early development, few studies have examined how changes in resource availability during other windows of development affect reproductive strategies and fitness independent of growth. 2. We manipulated food...

Data from: Rapid prey evolution can alter the structure of predator-prey communities

Ville-Petri Friman, Alexandre Jousset, Angus Buckling & V.-P. Friman
Although microevolution has been shown to play an important role in pairwise antagonistic species interactions, its importance in more complex communities has received little attention. Here, we used two Pseudomonas fluorescens prey bacterial strains (SBW25 and F113) and Tetrahymena thermophila protist predator to study how rapid evolution affects the structuring of predator–prey communities. Both bacterial strains coexisted in the absence of predation, and F113 was competitively excluded in the presence of both SBW25 and predator...

Data from: A trade-off between oxidative stress resistance and DNA repair plays a role in the evolution of elevated mutation rates in bacteria

Clara Torres-BarcelĂł, Gabriel Cabot, Antonio Oliver, Angus Buckling, R. Craig MacLean & C. Torres-Barcelo
The dominant paradigm for the evolution of mutator alleles in bacterial populations is that they spread by indirect selection for linked beneficial mutations when bacteria are poorly adapted. In this paper, we challenge the ubiquity of this paradigm by demonstrating that a clinically important stressor, hydrogen peroxide, generates direct selection for an elevated mutation rate in the pathogenic bacterium Pseudomonas aeruginosa as a consequence of a trade-off between the fidelity of DNA repair and hydrogen...

Data from: Defeating crypsis: detection and learning of camouflage strategies

Jolyon Troscianko, Alice E. Lown, Anna E. Hughes & Martin Stevens
Camouflage is perhaps the most widespread defence against predators in nature and an active area of interdisciplinary research. Recent work has aimed to understand what camouflage types exist (e.g. background matching, disruptive, and distractive patterns) and their effectiveness. However, work has almost exclusively focused on the efficacy of these strategies in preventing initial detection, despite the fact that predators often encounter the same prey phenotype repeatedly, affording them opportunities to learn to find those prey...

Data from: Singing in the moonlight: dawn song performance of a diurnal bird varies with lunar phase

Jennifer E. York, Andrew J. Young & Andrew N. Radford
It is well established that the lunar cycle can affect the behaviour of nocturnal animals, but its potential to have a similar influence on diurnal species has received less research attention. Here we demonstrate that the dawn song of a cooperative songbird, the white-browed sparrow weaver (Plocepasser mahali), varies with moon phase. When the moon was above the horizon at dawn, males began singing on average 10 minutes earlier if there was a full moon...

Data from: Size-dependent physiological responses of shore crabs to single and repeated playback of ship noise

Matthew A. Wale, Stephen D. Simpson & Andrew N. Radford
Anthropogenic noise has fundamentally changed the acoustics of terrestrial and aquatic environments, and there is growing empirical evidence that even a single noise exposure can impact behaviour in a variety of vertebrate organisms. Here we use controlled experiments to investigate how the physiology of a marine invertebrate, the shore crab (Carcinus maenas), is affected by both single and repeated exposure to ship-noise playback. Crabs experiencing ship-noise playback consumed more oxygen, indicating a higher metabolic rate...
