Table 6 Isolation by river distance and environmental heterogeneity across Varanus niloticus collection localities

From: Fine-scale genetic analysis of the exploited Nile monitor (Varanus niloticus) in Sahelian Africa

Variable

r

P ( r  < = 0)

R 2

River distance (km)

0.7978

Controlling for river distance:

   

Annual Precipitation (−km)

−0.2559

0.9590

 

Temperature Seasonality (−km)

0.1386

0.1210

 

Elevation (−km)

  1. The normalized Mantel’s statistic (r), significance [P(r < = 0)], and correlation coefficient (R 2) for the correlation between river distance (km) and genetic distance [F ST / (1-F ST )] are provided. The bottom three rows show results from the Partial Mantel tests, controlling for river distance. The bold value corresponds to a significant correlation (P<0.05).
