Alberta grassland plant data

Leaf and root traits and abundances and phylogeny for 76 grassland plant species from Alberta, Canada. Data set and collection methods are described in: <strong>S.W. Kembel and J.F. Cahill, Jr. 2011. Independent evolution of leaf and root traits within and among temperate grassland plant communities. PLoS ONE 6(6): e19992.</strong> <strong>File descriptions</strong> <strong>community.traits.csv</strong><br>- Each row represents abundance and traits measured for a species in a 20x20m sample plot. Traits should be log10-transformed prior to analysis. There are a few missing data points. Traits were measured on mature healthy leaves and on fine roots (&lt;2mm diameter) taken from representative individuals in each plot.<br>-abund: the abundance of each species in the plot. Abundance is an estimate of the percent cover of the species in the plot (0-100%) to the nearest 10%. Abundance was measured by noting presence of species in 10 quadrats placed within the plot.<br>-SLA: specific leaf area<br>-LeafArea: one-sided projected leaf area<br>-LeafThickness: leaf laminar thickness<br>-LeafTissueDens: leaf tissue density<br>-SRL: specific root length<br>-RootTissueDens: root tissue density<br>-RootDiam: average root diameter <strong>plot.metadata.csv</strong><br>- Plot-level metadata on habitat and site plus plot aspect/slope. <strong>species.phylogeny.txt</strong><br>- Species-level phylogeny with branch lengths proportional to estimated clade age. Tree backbone based on Davies et al. angiosperm phylogeny, within-family relationships resolved by hand using references cited in Kembel and Cahill 2011.
