Description
Summary:Isotope ratio mass spectrometry (IRMS): Leaf tissue samples from were dried in synthetic gauze bags on silica gel. Samples from species that occurred at more than seven sites (see Table SWATT_climate2.csv for locations) were selected, with the exception of one species (Grevillea hookeriana), which is only present at six sites. Leaves were ground using a ball mill (Retsch MM400 fitted with a Qiagen TissueLyser 24 adapter set). Leaves that did not grind within 3 minutes in the TissueLyzer (for example, Allocasuarina spinosissima) were ground in a 5 mL stainless steel grinding jar. For carbon and nitrogen isotope analysis, 2-2.5 mg of ground material was weighed to six significant figures into a tin capsule using an A&D BM-22 microbalance. Technical replicates for 13% of samples were run to correct for drift. Samples were combusted at 1000°C in an Elemental Analyser (EuroVector EuroEA 3000) in line with a continuous flow isotope ratio mass spectrometer (Nu Instruments Nu Horizon, University of Adelaide). Pure glycine, glutamic acid and triphenylamine (all calibrated to international C & N standards) were used as standards. A standard error of 0.07‰ was achieved. Two-point drift and size corrections based on glycine and glutamic acid standards were undertaken. Growth forms were attributed to species based on the growth forms described in the National Vegetation Attribute Manual (ESCAVI, 2003) with grasses and forbs further divided in to annual and perennial groups. Sub-specific determinations were ignored. Climate data were extracted from BIOCLIM layers modelled at 9 second resolution extracted from ANUCLIM 6.1 (Xu & Hutchinson, 2013).
