TL;DR: In contrast to the expanding edge, the low-latitude limit (rear edge) of species ranges remains understudied, and the critical importance of rear edge populations as long-term stores of species' genetic diversity and foci of speciation has been little acknowledged.

TL;DR: It is discussed why the tree growth habit should lead to these seemingly paradoxical features, such as great size, longevity, and high reproductive output.

TL;DR: A model‐based gross estimate suggests that, at the rangewide scale, historical levels of pollen flow are generally at least an order of magnitude larger than levels of seed flow and that pollen and seed gene flow vary independently across species.

TL;DR: This article argued that the strongly deterministic and reductionist BEM rely on biological assumptions that are much more commonly violated in nature than Pearson & Dawson (2003) assume, and that the statistical methods currently used for model validation overestimate model fits as a result of pseudoreplication.

TL;DR: The empirical evidence is synthesized considering relict habitats, abiotic and biotic constraints on population dynamics, mechanisms promoting population persistence, and uncertainties concerning their future prospects to identify three major types of climate relicts: those constrained primarily by climate-driven abiotic factors, those restricted to areas that are inaccessible to antagonistic species for climatic reasons, and those requiring a host or mutualistic species that is itself limited by climate.
