Each of full climate models (excluding vegetation and elevation variables for which there were no future projections) were subsequently projected onto predicted future climate layers from the IPCC 4th Assessment Report A1B climate change scenario for the decades 2050-2060 and 2080-2090. These predictions represent conservative efforts, however, as the predictions of atmospheric CO2 concentrations may be reached much sooner, as current emissions already exceed the trajectories of the highest scenarios. Thus, projections of genetic variation on the 2080-2090 climate scenarios are likely relevant for purposes of our study. From the predictions of genetic variation under current and future climate, we generated a change map for each of the target taxa, showing the level of predicted change in genetic variation between current conditions and those for the period 2080-2090.
