Data from: Individual-based measurements of light intensity provide new insights into the effects of artificial light at night on daily rhythms of urban-dwelling songbirds

Davide M. Dominoni, Esther O. Carmona-Wagner, Michaela Hofmann, Bart Kranstauber & Jesko Partecke
1. The growing interest in the effects of light pollution on daily and seasonal cycles of animals has led to a boost of research in recent years. In birds, it has been hypothesized that artificial light at night can affect daily aspects of behaviour, but one caveat is the lack of knowledge about the light intensity that wild animals, such as birds, are exposed to during the night. 2. Organisms have naturally evolved daily rhythms...

Data from: Genomic architecture of ecologically divergent body shape in a pair of sympatric crater lake cichlid fishes

Paolo Franchini, Carmelo Fruciano, Maria Spreitzer, Julia C. Jones, Frederico Henning, Kathryn R. Elmer, Axel Meyer & Maria L. Spreitzer
Determining the genetic bases of adaptations and their roles in speciation are prominent issues in evolutionary biology. Cichlid fish species flocks are a prime example of recent rapid radiations often associated with adaptive phenotypic divergence from a common ancestor within a short period of time. In several radiations of freshwater fishes divergence in eco-morphological traits including body shape, color, lips and jaws, are thought to underlie their ecological differentiation, specialization and – ultimately – speciation....

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: Shaping development through mechanical strain: the transcriptional basis of diet-induced phenotypic plasticity in a cichlid fish

Helen M. Gunter, Shaohua Fan, Fan Xiong, Paolo Franchini, Carmelo Fruciano & Axel Meyer
Adaptive phenotypic plasticity, the ability of an organism to change its phenotype to match local environments, is increasingly recognized for its contribution to evolution. However, few empirical studies have explored the molecular basis of plastic traits. The East African cichlid fish Astatoreochromis alluaudi displays adaptive phenotypic plasticity in its pharyngeal jaw apparatus, a structure that is widely seen as an evolutionary key innovation that has contributed to the remarkable diversity of cichlid fishes. It has...

Data from: Endocrine phenotype, reproductive success and survival in the great tit, Parus major

Jenny Q. Ouyang, Peter Sharp, Michael Quetting & Michaela Hau
A central goal in evolutionary ecology is to characterize and identify selection patterns on the optimal phenotype in different environments. Physiological traits, such as hormonal responses, provide important mechanisms by which individuals can adapt to fluctuating environmental conditions. It is therefore expected that selection shapes hormonal traits, but the strength and the direction of selection on plastic hormonal signals are still under investigation. Here, we determined whether, and in which way, selection is acting on...

Data from: Phenotypic and genetic divergence within a single whitefish form – detecting the potential for future divergence

Philipp Emanuel Hirsch, Reiner Eckmann, Claus Oppelt & Jasminca Behrmann-Godel
Human-induced nutrient input can change the selection regime and lead to the loss of biodiversity. For example, eutrophication caused speciation reversal in polymorphic whitefish populations through a flattening of littoral-pelagic selection gradients. We investigated the current state of phenotypic and genetic diversity in whitefish (Coregonus macrophthalmus) in a newly restored lake whose nutrient load has returned to pre-eutrophication levels and found that whitefish spawning at different depths varied phenotypically and genetically: individuals spawning at shallower...
