Figure
1. Map of study area, and genetic structuring among the pike,Esox lucius, populations. The map shows the locations and
spawning ecotypes of the study populations (blue: freshwater, black:
anadromous, and red: resident). It was created in Adobe Photoshop CC, v.
2015.0.1, and is a combined and modified version of two base maps (one
of Scandinavia, and one of Sweden) that are available from Wikimedia
Commons under the non-restrictive creative commons license. The distruct
plots show the genetic structuring among the populations for the most
likely number of genetic clusters (K) suggested by fastSTRUCTURE.
The fastSTRUCTURE analyses were run with two different datasets (one
’neutral’ and one ’adaptive’) with data for 234 individuals.
