Fig. 3

Path diagram based on structural equation modelling showing how the number of adventitious branches per thallus in Baltic Sea Fucus spp. populations is affected by different environmental factors. Red arrows indicate negative path coefficients, blue arrows indicate positive path coefficients, and dashed gray arrows indicate non-significant paths. All path coefficients are standardized. Variables presented in rectangles are biotic while those presented in ovals are abiotic (with the exception of adventitious branches). Percentages indicate the variance explained by the model, all correlation coefficients are low (p < 0.00001)
