Some of the earliest candidate genes were identified from associations between allozyme allele frequencies and environmental variation. One such example is the clinal polymorphism in the arginine kinase (<em>Ak</em>) gene in the marine snail <em>Littorina fabalis</em>. While other enzyme loci do not show differences in allozyme frequencies among populations, the <em>Ak</em> alleles are near differential fixation across repeated wave exposure gradients in Europe. Here, we use this case to illustrate how a new sequencing toolbox can be employed to characterize the genomic architecture associated with historical candidate genes. We found that the <em>Ak</em> alleles differ by 9 non-synonymous substitutions, which perfectly explain the different migration patterns of the allozymes during electrophoresis. Moreover, by exploring the genomic context of the <em>Ak</em> gene, we found that the three main <em>Ak</em> alleles are located on different arrangements of a putative chromosomal inversion that reaches near fixation at the opposing ends of two transects covering a wave exposure gradient. This shows <em>Ak</em> is part of a large (3/4 of the chromosome) genomic block of differentiation, in which <em>Ak</em> is unlikely to be the only target of divergent selection. Nevertheless, the non-synonymous substitutions among <em>Ak</em> alleles and the complete association of one allele with one inversion arrangement suggest that the <em>Ak</em> gene is a strong candidate to contribute to the adaptive significance of the inversion.</p> <p> </p> <p> </p>

Guadeloupe Snails Metacommunity
<p><span>Metacommunity structure reflects the interplay of various processes, including niche filtering, extinction/colonization, and interspecific interactions. Spatial patterns of species distributions are often analyzed to infer these processes. However, such inferences rely on often unrealistic equilibrium assumptions, and remain ambiguous, as different processes can produce similar patterns. Temporal data may improve these inferences. For example, stochastic species turnover may occur in local communities, while, on the long run, temporal changes are kept within limits set by locally available niches. Our objective is to explore how the joint analysis of spatial and temporal patterns can clarify the contribution of different processes to metacommunity structure. We recorded the occurrences of 21 freshwater mollusc species, and environmental data, in 250 sites over 17 successive years in a network of ponds in Guadeloupe (Lesser Antilles). We analyzed variation in α and β-diversities in space and time, and used a joint-species distribution mode to characterize species-environment and species-species relationships. Local communities showed pronounced temporal variation reflecting both imperfect species detection and true stochastic species turnover. On the long term however, local communities were largely controlled by niche filtering along two main environmental gradients, one driven by site connectivity, the other by hydrological stability and aquatic vegetation. Two gastropod clades, caenogastropods and pulmonates, showed contrasted spatio-temporal distributions resulting from different responses to these gradients, and these distributions seemed little altered by interspecific competition. Our study illustrates the benefit of using spatiotemporal metacommunity data to discern long-term impacts of niche filtering and species interactions behind short-term stochasticity.</span></p>
