“…We also found no relationship between genetic differentiation and geographical distance either in combination with the hybrid scenario or by itself. Contrary to previous work performed within Swiss lake systems (Lucek et al 2013), the pattern of genetic population divergence observed here is not likely driven by habitat dependent selection because, although genetically differentiated, many populations occupy similar (e.g., GIP-MOE, both stream habitats), or even the same, habitats (e.g., both RHO-and NEU-like individuals recovered from STS, ALL, GLA, GUP, YVB and YVM). Thus, although parallel habitat based divergence seems evident at a finer, more lake-specific level (Lucek et al 2013), the nature of genetic boundaries between the geographically more inclusive genetic populations identified in the present work is less obvious.…”
