Fig. 5From: Population regulation in Gyrodactylus salaris – Atlantic salmon (Salmo salar L.) interactions: testing the paradigmEffect of different grouping models on unexplained residual variance in G. salaris population growth rate. Models based on conventional groupings of Atlantic salmon according to race or geographical origin, or based on relative rate of population growth, fail to account for as much variance as the models in which all stocks are treated separately, or in which replicates (but not stocks) are groupedBack to article page
