Fig. 3From: Low genetic and phenotypic divergence in a contact zone between freshwater and marine sticklebacks: gene flow constrains adaptationCorellograms showing the results of spatial autocorrelation analyses for the individuals sampled continuously from the river mouth and upstream. In all plots the shading along lines denotes 95% confidence intervals of r values. The analyses were conducted using GenAlEx 6.5 [61, 102]. a Analysis involving all individuals. The dashed lines denote the upper and lower confidence intervals for the case of no structure (i.e. correlation coeffificent r = 0; not shown in the other plots). b Separate corellograms for full-plated and low + partial-plated individuals. c Separate correlograms for male and femalesBack to article page
