Abstract: Ongoing climate change has affected the ecological dynamics of many species and is expected to impose natural selection on ecologically important traits. Droughts and other anticipated changes in precipitation may be particularly potent selective factors, especially in arid regions. Here we demonstrate the evolutionary response of an annual plant, Brassica rapa, to a recent climate fluctuation resulting in a multiyear drought. Ancestral (predrought) genotypes were recovered from stored seed and raised under a … Show more

“…This differentiation has occurred within contiguous grassland over a very small spatial extent (thirty 9‐m 2 plots spread over approximately 0.2 ha grassland), and happened rapidly, during 15 years of climate change manipulations. Similarly, rapid genetic change occurring in response to a natural drought has been documented in the annual species Brassica rapa (Franks et al ., 2007). Treatment‐level genetic structure at BCCIL is unlikely to be dominated by neutral spatial genetic structuring because each treatment is replicated in each spatial experimental block.…”

“…With baseline parameter values, the duration of clusters was increased up to 200 per cent when including days with single open flowers in the disjunctions between clusters. Furthermore, our model did not allow the joint evolution of other isolating mechanisms, although some can occur within the duration of the clusters we observed ( Turelli et al 2001;Ramsey et al 2003;Primack et al 2004;Hendry & Day 2005;Savolainen et al 2006;Franks et al 2007). For example, temporal isolation can arise from pollinator shifts or preferences for specific floral traits (Coyne & Orr 2004;Johnson 2006) or coevolution of pollinators and plants (Bhattacharyay & Drossel 2005;Sargent & Otto 2006).…”

“…When changes in environmental conditions occur, species can shift their distributional range (i.e., Parmesan & Yohe, 2003; Perry, Low, Ellis, & Reynolds, 2005) in order to migrate in more suitable habitats. Alternatively, organisms can compensate environmental fluctuations with phenotypic plasticity (Franks, Sim, & Weis, 2007; Franks, Weber, & Aitken, 2014; Ghalambor, McKay, Carroll, & Reznick, 2007; Gienapp, Teplitsky, Alho, Mills, & Merilä, 2008; Merilä & Hendry, 2014), which can be highlighted at different hierarchy levels of the biological organization, through adjustments of gene expression (i.e., Granados‐Cifuentes, Bellantuono, Ridgway, Hoegh‐Guldberg, & Rodriguez‐Lanetty, 2013; Jeukens, Bittner, Knudsen, & Bernatchez, 2009; Larsen, Nielsen, Williams, & Loeschcke, 2008; Larsen et al., 2007; Pavey, Collin, Nosil, & Rogers, 2010; Swindell, Huebner, & Weber, 2007), developmental features (i.e., Sultan, 2000; West‐Eberhard, 2005), and life‐history traits (Dowdall et al., 2012). Moreover, species can also evolve genetic differentiation among populations (i.e., local adaptation; Kawecki & Ebert, 2004) due to ecological selection (Keller & Seehausen, 2012; Schluter, 2009) and intraspecific competition (García‐Ramos & Huang, 2013).…”
