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>

Fig. 1 in Resolving the Ophioderma longicauda (Echinodermata: Ophiuroidea) cryptic species complex: five sisters, three of them new
Fig. 1. Phylogenetic relationships and distribution of species of Ophioderma Müller & Troschel, 1840 in the Northeast and Tropical Atlantic Ocean and the Mediterranean Sea. A. Simplified phylogenetic relationships among species of Ophioderma described in this study, modified from Weber et al. (2019). Summary of reproductive strategy: S = broadcast spawner; B = brooder. Correspondence between species names, nuclear genetic clusters and COI mitochondrial lineages is summarized from Boissin et al. (2011) and Weber et al. (2019). C6 is tentatively assigned to O. zibrowii sp. nov. because it occurs far from the type locality and brooding species are expected to have low dispersal rates, leading to low gene flow between populations. B. Distribution of species of Ophioderma in the Northeast and Tropical Atlantic Ocean. C. Distribution of species of Ophioderma in the Mediterranean Sea.
