Intraspecific variation in reproductive barriers between two closely-related Arabidopsis sister species
<p>Reproductive isolation (RI) is a critical component of speciation and varies strongly in timing and strength among different sister taxa, depending e.g.<em>,</em> on the geography of speciation and divergence time. However, these factors may also produce variation in timing and strength among populations within species. Here we tested for variation in the expression of RI among replicate population pairs between the sister taxa <em>Arabidopsis lyrata</em> subsp. <em>lyrata</em> and <em>A. arenicola</em>. While the former is predominantly outcrossing, the latter is predominantly selfing<em>.</em> We focused on intrinsic prezygotic and postzygotic RI as both species occur largely in allopatry. We assessed RI by performing within-population crosses and interspecific between-population crosses, and by raising offspring. RI was generally high between all interspecific population pairs, but it varied in timing and strength depending on population history. Prezygotic isolation was strongest between the closest-related population pair, while early postzygotic isolation was high for all other population pairs. Furthermore, the timing and strength of RI depended strongly on cross direction. Our study provides empirical support that reproductive barriers between species are highly variable among population pairs and asymmetric within population pairs, and this variation seems to follow patterns typically described across species pairs.</p>
Data from: Heat tolerance is more variable than cold tolerance across species of Iberian lizards after controlling for intraspecific variation
<ol> <li>The widespread observation that heat tolerance is less variable than cold tolerance ('cold-tolerance asymmetry') leads to the prediction that species exposed to temperatures near their thermal maxima should have reduced evolutionary potential for adapting to climate warming. However, the prediction is largely supported by species-level global studies based on single estimates of both physiological metrics per taxon.</li> <li>We ask if cold-tolerance asymmetry holds for Iberian lizards after accounting for intraspecific variation in critical thermal maxima (CT<i><sub>max</sub></i>) and minima (CT<i><sub>min</sub></i>). To do so, we quantified CT<i><sub>max</sub></i> and CT<i><sub>min</sub></i> for 58 populations of 15 Iberian lizard species (299 individuals). Then, we randomly selected one population from each study species (population sample = 15 CT<i><sub>max</sub></i> and CT<i><sub>min</sub></i> values), tested for variance homoscedasticity across species, and repeated the test for thousands of population samples as if we had undertaken the same study thousands of times, each time sampling one different population per species.</li> <li>The ratio of variances in CT<i><sub>max</sub></i> to CT<i><sub>min</sub></i> across species varied up to 16-fold depending on the populations chosen. Variance ratios show how much CT<i><sub>max</sub></i> departs from the cross-species mean compared to CT<i><sub>min</sub></i>, with a unitary ratio indicating equal variance of both thermal limits. Sampling one population per species was six times more likely to result in the observation of greater CT<i><sub>max</sub></i> variance ('heat-tolerance asymmetry') than cold-tolerance asymmetry. The null hypothesis of equal variance was twice as likely for cases of cold-tolerance asymmetry than for the opposite scenario.</li> <li>Range-wide, population-level studies that quantify heat and cold tolerance of individual species are urgently needed to ascertain the global prevalence of cold-tolerance asymmetry. While broad latitudinal clines of cold tolerance have been strongly supported, heat tolerance might respond to smaller-scale climatic and habitat factors hence go unnoticed in global studies. Studies investigating physiological responses to climate change should incorporate the extent to which thermal traits are characteristic of individuals, populations and/or species.</li> </ol>
