Resurrection ecology in Viola arvensis
<p><span><strong>Premise of the study:</strong> </span><span>As part of global change, climate warming and pollinator decline are expected to affect plant phenology and plant-pollinator interactions. This paper aims at characterizing rapid evolution of life history traits and floral traits over two decades in the wild pansy (<em>Viola arvensis</em>), a common weed in agrosystems. </span></p> <p><strong><span>Methods</span></strong><span><strong>:</strong> We used a resurrection ecology approach with genotypes sampled in 1991 and 2012 from a population in Burgundy (France). The species has a mixed mating system (hereafter: mixed selfer) and presents a floral polymorphism. In order to correct for maternal effects, plant traits were measured in the second generation in a common garden (after a refreshing generation) to characterize plant evolution during the two decades. In addition, historical population selfing rates in the 1991 and 2012 were inferred from microsatellites markers through heterozygote deficiency and identity disequilibrium. </span></p> <p><strong><span>Key results</span></strong><span><strong>:</strong> Phenotypic data revealed a significant advance in flowering date, reduced flower sizes and a higher propensity of plant to set seed by autonomous selfing. Moreover, we detected a change in color morph frequency with an increase of the pale morph frequency. In accordance with phenotypic data, the neutral genetic data revealed in increase in historical selfing rates from s=0.68 in 1991 to s=0.86 in 2012. </span></p> <p><strong><span>Conclusions</span></strong><span><strong>:</strong> Taken together, such data suggest that the wild pansy, as mixed selfer, is evolving a selfing syndrome that may be the consequence of reduced pollinator activity in agrosystems. </span></p>

Data from: Resurrection ecology in Artemia
Resurrection Ecology (RE) is a very powerful approach to address a wide range of question in ecology and evolution. This approach rests on using appropriate model systems, and only few are known to be available. In this paper, we show that Artemia has multiple attractive features (short generation time, cyst bank and collections, well documented phylogeography and ecology) for a good RE model. We show in detail with a case study how cysts can be recovered from sediments to document the history and dynamics of a biological invasion. We finally discuss with precise examples the many RE possibilities with this model system: adaptation to climate change, to pollution, to parasites, to invaders and evolution of reproductive systems.
