From: Parallel divergent adaptation along replicated altitudinal gradients in Alpine trout
Sampling sites along altitudinal transects replicated in the Alpine section of three major European drainages. Major drainages are indicated by different shading (medium grey=Rhine; light grey=Po; hatched=Rhone; dark grey=Danube) and river systems within drainages are labelled in italics. Different symbols indicate different altitudinal zones: squares < 500m, circles = 500-1000m, triangles >1000m above sea level. Inset table: Native and current distribution of five major evolutionary trout lineages (based on Largiadèr & Scholl 1995, 1996) corresponding to different haplogroups of Bernatchez (2001) and species (in parentheses) of Kottelat & Freyhof (2007): AT=Atlantic (S. trutta), ME=Mediterranean (S. rhodanensis), AD=Adriatic (S. cenerinus), MA=marble trout (S. marmorata), DA=Danubian (S. labrax).
