Study area: The Cantabrian Mountains located in NW spain.
Information on biogeographic regions was obtained from the Spanish Ministry of Agriculture, Food and Environment (http://www.magrama.gob.es/). Information on protected areas was obtained from the BCN200 database of the Spanish Geographic Institute (www.ign.es); SPC Special Protection Areas, SCI Sites of Community Importance. Figure was created in ArcGIS 10.2 (Esri 2014).

Species functional traits and functional groups considered in this study.
Table 2.
Environmental variables entered as predictors in OLS models after excluding correlated variables.
The mean and/or the standard deviation value of the environmental variables were extracted for each 10x10 km UTM sampling unit (See S2 Table for more details).
Fig 2.
Results of the most parsimonious models (ordinary least squares regression and autoregressive models SAR or CAR) testing the effect of environmental predictors on both functional redundancy (FR) and diversity (FD).
Significance levels, sign of the effect and variance explained by models are indicated. See Table 2 for codes of environmental variables. Only variables included as predictors in some of the most parsimonious models are shown.
