Impact/Purpose:
This Data Article is an invited contribution to complement a manuscript submitted to the Journal of Experimental Marine Biology and Ecology (Nitrogen uptake and allocation estimates for Spartina alterniflora and Distichlis spicata, ORD-023763). This highly detailed study makes a valuable contribution to our understanding of how salt marsh plants take up and allocate nitrogen. The individual measurements and source code contained in this Data Article will feed modeling exercises and contribute to the development of our (coastal ecologists and managers) synthetic understanding of how nitrogen is taken up and retained by salt marshes.
Description:
We present four datasets that provide information on primary production, nitrogen (N) uptake and allocation in two salt marsh dominants, short-form Spartina alterniflora and Distichlis spicata. These four datasets were generated during a month-long stable isotope (15N) tracer study described in the companion manuscript [1]; DOI:10.1016/j.jembe.2018.07.006. They include an allometry dataset containing mass and height data for individual plants harvested from Colt State Park, Bristol, Rhode Island and used to nondestructively estimate plant masses. A second dataset contains weekly stem height measurements collected over the course of a month-long15N tracer study. Also included are high resolution data from 49 vegetated compartments (leaves, stems, fine/coarse roots, rhizomes) and bulk sediment depth intervals, reporting the mass, carbon and N concentrations, and stable isotope ratios as measured following the harvest of cores over time. Additionally, we provide a complementary dataset with estimates of microbial removal from potential and ambient denitrification enzyme assays. These data, along with source code used in their analysis, are compiled in the NitrogenUptake2016 R package available from the Comprehensive R Archive Network.
