TL;DR: As all tree species will be suffering lags, interspecific competition may weaken, facilitating persistence under suboptimal conditions, and species with small populations, fragmented ranges, low fecundity, or suffering declines due to introduced insects or diseases should be candidates for facilitated migration.

TL;DR: Responding to climate change will likely require that the quantitative traits of populations again match their environments, and it is found that genetic differentiation between populations and clinal variation along environmental gradients were very common.

TL;DR: Analytical approximations and individual‐based simulations are used to explore how genetic architecture evolves when two populations connected by migration experience stabilizing selection toward different optima and find that adaptation with migration tends to result in concentrated genetic architectures with fewer, larger, and more tightly linked divergent alleles.

TL;DR: It is shown that tight clustering of the loci involved in local adaptation tends to evolve on biologically realistic time scales, which suggests that genomic rearrangements may often be an important component of local adaptation and the evolution of genomic islands of divergence.

TL;DR: It is found that genetic divergence is lower in sympatric and parapatric comparisons, consistent with a role for gene flow in eroding neutral differences, and the results indicate that the functional architecture of genomes plays a larger role in shaping genomic divergence than does the geography of speciation.
