Data from: Latitudinal and voltinism compensation shape thermal reaction norms for growth rate

Lisa N S Shama, Melina Campero-Paz, K. Mathias Wegner, Marjan De Block & Robby Stoks
Latitudinal variation in thermal reaction norms of key fitness traits may inform about the response of populations to climate warming, yet their adaptive nature and evolutionary potential is poorly known. We assessed the contribution of quantitative genetic, neutral genetic and environmental effects to thermal reaction norms of growth rate for populations of the damselfly Ischnura elegans. Among populations, reaction norms differed primarily in elevation suggesting that time constraints associated with shorter growth seasons in univoltine,...

Data from: Exploring possible human influences on the evolution of Darwin's finches

Luis Fernando De León, Joost A.M. Raeymaekers, Eldredge Bermingham, Jeffrey Podos, Anthony Herrel & Andrew P. Hendry
Humans are an increasingly common influence on the evolution of natural populations. Potential arenas of influence include altered evolutionary trajectories within populations and modifications of the process of divergence among populations. We consider this second arena in the medium ground finch (Geospiza fortis) on Santa Cruz Island, Galápagos, Ecuador. Our study compared the G. fortis population at a relatively undisturbed site, El Garrapatero, to the population at a severely disturbed site, Academy Bay, which is...

Data from: Colony stage and not facultative policing explains pattern of worker reproduction in the Saxon wasp

Wim Bonckaert, Jelle S Van Zweden, Patrizia D'Ettorre, Johan Billen & Tom Wenseleers
Inclusive fitness theory predicts that in colonies of social Hymenoptera headed by a multiple mated queen, workers should benefit from policing eggs laid by other workers. Foster & Ratnieks (2000) provided evidence that in the vespine wasp Dolichovespula saxonica, workers police other workers' eggs only in colonies headed by a multiple mated queen, but not in those headed by a single mated one. This conclusion, however, was based on a relatively small sample size and...

Data from: Quantitative genetic inheritance of morphological divergence in a lake-stream stickleback ecotype pair: implications for reproductive isolation

Daniel Berner, Renaud Kaeuffer, Anne-Catherine Grandchamp, Joost A. M. Raeymaekers, Katja Räsänen & Andrew P. Hendry
Ecological selection against hybrids between populations occupying different habitats might be an important component of reproductive isolation during the initial stages of speciation. The strength and directionality of this barrier to gene flow depends on the genetic architecture underlying divergence in ecologically relevant phenotypes. We here present line cross analyses of inheritance for two key foraging-related morphological traits involved in adaptive divergence between stickleback ecotypes residing parapatrically in lake and stream habitats within the Misty...

Data from: Genomic signature of natural and anthropogenic stress in wild populations of the waterflea Daphnia magna: validation in space, time and experimental evolution

Luisa Orsini, Katina I. Spanier & Luc De Meester
Natural populations are confronted with multiple selection pressures resulting in a mosaic of environmental stressors at landscape level. Identifying the genetic underpinning of adaptation to these complex selection environments and assigning causes of natural selection within multidimensional selection regimes in the wild is challenging. The water flea Daphnia is a renown ecological model system with its well-documented ecology, the possibility to analyze subfossil dormant egg banks, and the short generation time allowing an experimental evolution...

Data from: Levels of clonal mixing in the black bean aphid Aphis fabae, a facultative ant mutualist

Amélie Vantaux, Johan Billen & Tom Wenseleers
Aphids are a worldwide pest and an important model in ecology and evolution. Little is known, however, of the genetic structure of their colonies at a microgeographic level. For example, it remains largely unknown whether most species form monoclonal or polyclonal colonies. Here, we present the first detailed study on levels of clonal mixing in a nonsocial facultative ant mutualist, the black bean aphid Aphis fabae. In contrast to the earlier suggestion that colonies of...

Data from: Temporal genetic stability and high effective population size despite fisheries-induced life-history trait evolution in the North Sea sole.

Els L Cuveliers, Filip A M Volckaert, Adriaan D Rijnsdorp, Maarten H D Larmuseau & Gregory E Maes
Heavy fishing and other anthropogenic influences can have profound impact on a species’ resilience to harvesting. Besides the decrease of the census and effective population size, strong declines in mature adults and recruiting individuals may lead to almost irreversible genetic changes in life-history traits. Here, we investigated the evolution of genetic diversity and effective population size in the heavily exploited sole (Solea solea), through the analysis of historical DNA from a collection of 1379 sole...
