Genetic diversity and differentiation of populations of Anthyllis vulneraria along elevational and latitudinal gradients
<p>The abundant centre model (ACM) predicts that the suitability of environmental conditions for a species decreases from the centre of its distribution towards its range periphery and consequently its populations will become scarcer, smaller and more isolated, resulting in lower genetic diversity and increased differentiation. However, little is known about whether genetic diversity shows similar patterns along elevational and latitudinal gradients with similar changes in important environmental conditions. Using microsatellite markers we studied the genetic diversity and structure of 20 populations each of <em>Anthyllis vulneraria </em>along elevational gradients in the Alps from the valleys to the elevational limit (2500 m), and along a latitudinal gradient (2500 km) from Central Europe to the range margin in northern Scandinavia. Both types of gradients corresponded to a 11.5 °C difference in mean annual temperature. Genetic diversity strongly declined and differentiation increased with latitude in line with the predictions of the ACM. However, as population size did not decline with latitude and genetic diversity was not related to population size in <em>A. vulneraria</em>, this pattern is not likely to be due to less favourable conditions in the North, but due to serial founder effects during the post-glacial recolonization process. Genetic diversity was not related to elevation, but we found significant isolation by distance along both gradients, although the elevational gradient was shorter by orders of magnitude. Subarctic populations differed genetically from alpine populations indicating that the northern populations did not originate from high elevational Alpine ones. Our results support the notion that postglacial latitudinal colonization over large distances resulted in a larger loss of genetic diversity than elevational range shifts. The lack of genetic diversity in subarctic populations may threaten their long-term persistence in the face of climate change, whereas alpine populations could benefit from gene flow from low-elevation populations.</p>
Clinal variation in quantitative traits but not in evolutionary potential along elevational and latitudinal gradients in the widespread Anthyllis vulneraria
<p><strong>Premise of the study</strong></p> <p>Strong elevational and latitudinal gradients allow the study of genetic differentiation in response to similar environmental changes. However, it is uncertain whether the environmental changes along the two types of gradients result in similar genetically based changes in quantitative traits. Peripheral arctic and alpine populations are thought to have a lower evolutionary potential than more central ones. </p> <p><strong>Methods </strong></p> <p>We studied quantitative traits of the widespread <em>Anthyllis vulneraria</em> in a common garden. Plants originated from 20 populations along a 2000 m elevational gradient from the lowlands to the elevational limit of the species in the Alps, and from 20 populations along a 2400 km latitudinal gradient from the centre of the distribution of the species in Central Europe to its northern distributional margin.</p> <p><strong>Key results</strong></p> <p>Several traits showed similar clinal variation with elevation and latitude of origin. Higher Q<sub>ST</sub>-values than F<sub>ST</sub>-values in some traits indicated divergent selection. The same traits were subject to strongly diversifying selection among populations (high Q<sub>ST</sub>) and strong stabilising selection within populations (low evolvability). Genetic diversity of most quantitative traits and neutral molecular markers was only weakly correlated. Plasticity in response to benign conditions declined with both increasing elevation and latitude of origin, but the evolvability of most traits did not.</p> <p><strong>Conclusions </strong></p> <p>The clinal variation suggests adaptive differentiation of quantitative traits along the two gradients. Our results indicate that the evolutionary potential of peripheral populations is not necessarily reduced. However, lower plasticity may threaten their survival under rapidly changing climatic conditions.</p>
