TLDR
In this paper, the authors used a genome scan to identify temperature-related adaptive differentiation of individuals of the tree species Fagus sylvatica and assessed spatial and temporal variation in gene frequency at the locus identified as being under selection.Abstract:
Rapid increases in global temperature are likely to impose strong directional selection on many plant populations, which must therefore adapt if they are to survive. Within populations, microgeographic genetic differentiation of individuals with respect to climate suggests that some populations may adapt to changing temperatures in the short-term through rapid changes in gene frequency. We used a genome scan to identify temperature-related adaptive differentiation of individuals of the tree species Fagus sylvatica . By combining molecular marker and dendrochronological data we assessed spatial and temporal variation in gene frequency at the locus identified as being under selection. We show that gene frequency at this locus varies predictably with temperature. The probability of the presence of the dominant marker allele shows a declining trend over the latter half of the 20th century, in parallel with rising temperatures in the region. Our results show that F. sylvatica populations may show some capacity for an in situ adaptive response to climate change. However as reported ongoing distributional changes demonstrate, this response is not enough to allow all populations of this species to persist in all of their current locations.read more

Divergent selection and heterogeneous genomic divergence.
TL;DR: It is concluded that divergent selection makes diverse contributions to heterogeneous genomic divergence, and the number, size, and distribution of genomic regions affected by selection varied substantially among studies, leading us to discuss the potential role of Divergent selection in the growth of regions of differentiation (i.e. genomic islands of divergence), a topic in need of future investigation.

Climate change and evolution: disentangling environmental and genetic responses
TL;DR: The available evidence points to the overall conclusion that many responses perceived as adaptations to changing environmental conditions could be environmentally induced plastic responses rather than microevolutionary adaptations, and clear‐cut evidence indicating a significant role for evolutionary adaptation to ongoing climate warming is conspicuously scarce.

Climate change and plant regeneration from seed
TL;DR: Increased research in understudied ecosystems, on key issues related to seed ecology, and on evolution of seed traits in nonweedy species is needed to more fully comprehend and plan for plant responses to global warming.

TL;DR: The purpose of this discussion is to offer some unity to various estimation formulae and to point out that correlations of genes in structured populations, with which F-statistics are concerned, are expressed very conveniently with a set of parameters treated by Cockerham (1 969, 1973).

TL;DR: The AFLP technique provides a novel and very powerful DNA fingerprinting technique for DNAs of any origin or complexity that allows the specific co-amplification of high numbers of restriction fragments.

The genetic legacy of the Quaternary ice ages
TL;DR: The present genetic structure of populations, species and communities has been mainly formed by Quaternary ice ages, and genetic, fossil and physical data combined can greatly help understanding of how organisms were so affected.
