CWM_traits for aquatic plants

Data was collected in a field survey in August 2014 comprising 30 sites in the Gulf of Finland, Northern Baltic Sea. Sampled sites occurred along a wave exposure gradient and were divided into outer, middle and inner archipelago areas (see article for details). At each site, five replicate plots (1m2 each) were sampled. Trait measurements were weighted by the shoot densities of each species to retrieve the community-weighted mean trait value and standardized to have a mean of 0 and variance of 1. See article for more information on the trait measurements. The data was used in constructing Structural Equation Models. Abbreviated headlines are as follow: “CWM_SLA” = community-weighted mean specific leaf area, “CWM_Root” = community-weighted mean root length, “CWM_Hmax” = community-weighted mean maximum vegetative height, “CWM_RS = community-weighted mean root to shoot ratio, CWM_LeafN = community-weighted mean leaf nitrogen concentration, “CWM_RootN” = community-weighted root nitrogen concentration, “CWM_Leafd15N” = the community-weighted mean delta 15N of youngest leaves, “CWM_Leafd13C” = the community-weighted mean delta 13C of youngest leaves, “CWM_Rootd15N” = the community-weighted mean delta 15N of youngest roots, “lnSilt” = the ln-transformed silt-fraction and “lnPrimprod” = the ln-transformed community primary production.
