Figure 2: Some of the forces contributing to patterns of
contemporary genetic diversity within populations. A changing
environment (e.g. glacial-interglacial periods through the Pleistocene)
impacts population size and the relative strength of genetic drift.
However, the population can become adapted to new environmental
conditions through natural selection, potentially also impacting on
population size. Finally, genetic drift will impact the efficacy of
natural selection in the population. de Jong et al. (2020) examine the
interaction of these forces in roe deer (Capreolus spp.),
focussing particularly on European roe deer (C. capreolus).
