Pattern of recruitment variability in the geographical range of the exploited northeast Atlantic fish species

It has long been argued that populations living on the edges of the species geographical range should exhibit stronger environmentally imposed variations in abundances than populations living near the centre of this range. This so-called 'Species Range Hypothesis' is tested here for the re...
