Among the climate variables, annual mean temperature explained the
largest (52.0%) and only significant (F = 6.95, p < 0.05)
amount of genetic variance in outlier loci. This was followed by trends
for an effects of mean diurnal range (F = 5.01, p = 0.06) and
precipitation seasonality (F = 4.33, p = 0.07), which respectively
explained 35.1% and 29.1% of genetic variance (Table 3). The climate
variable with the strongest influence on outlier loci as detected by RDA
was annual mean temperature, which was associated with 37.1% of the
markers, followed by mean diurnal range which was associated with 20.8%
of markers.
Among the outlier loci detected by all methods, the primary associations
were with annual mean temperature (27.5%) and annual precipitation
(25.4%). The same picture arises if only candidate loci that were
detected by at least two methods are considered. Here, 28.6% of loci
are associated with annual mean temperature and 25.4% are associated
with annual precipitation (Table S7).
