Abstract:

This data set was collected as a part of Brian Houseman's MS Thesis, Post-fire Variability in Siberian Alder in Interior Alaska: Distribution Patterns, Nitrogen Fixation Rates, and Ecosystem Consequences (December 2017). Data include Siberian alder (Alnus viridis ssp. fruticosa) leaf chemistry (N, C, P) and specific leaf mass. Data were collected on study plots established across two burn scars (2004 Boundary Fire and 1971 Wickersham Dome Fire) within the Yukon-Tanana Uplands ecoregion of interior Alaska. The data were collected in 2014.

Description:
This dataset contains leaf chemistry information for each Siberian alder (Alnus viridis ssp. fruticosa) that was sampled for nitrogen fixation. Siberian alder leaf chemistry data are assoicated with the same Siberian alder individual plants that were sampled for nitrogen fixation in 2015 (re: nitfix_2015.csv) at study plots from the Boundary Fire (n=19) and Wickersham Dome fire (n=21) that were a subsample of study plots sampled for releve plant cover estimates in 2014 (re: releve_plots_2014.csv). This data set was collected as a part of Brian Houseman's MS Thesis.

Description:

Experimental Design

This study was designed to assess Siberian alder N-fixation input variability across post-fire age, fire severity levels, and stand types. Study plots were randomly located to capture the variability of environmental factors across the landscape. Detailed site information for each research location in this study is available within the BNZ-LTER Data Set entitled Post-fire Variability in Siberian Alder in Interior Alaska: Distribution Patterns, Nitrogen Fixation Rates, and Ecosystem Consequences X - Research Project Site Information 2014.

Methods

FIELD: For each alder that was sampled for nodule-level N-fixation in 2015 (n = 48 alders across 21 plots in the WDF; n = 48 alders across 19 plots in the BF) a minimum of 10 leaves were collected at the time of N-fixation sampling and used to estimate specific leaf mass (mg cm-2), and total N, C, and P. The leaves were randomly collected across the complete range of a plant's leaf size and canopy position, and a leaf punch (7.07 cm2) was taken from each leaf and pooled as one sample. LAB: Leaf samples were dried at 40 deg C until reaching constant mass, and then weighed to the nearest tenth of a milligram. Total dry sample weight was divided by total sample area to get specific leaf mass (mg x cm-2) for each plant. Each leaf sample was then ground separately on a ball mill before measuring total carbon (% C) and total nitrogen (% N) content on a LECO TruSpec CN analyzer (LECO Corporation, St. Joseph, Michigan, USA). Total (% P) was measured colormetrically using a BranLuebbe AA3 autoanalyzer (SEAL Analytical Inc., Mequon, Wisconsin, USA) following a perchloric acid digest, wherein sample reaction color development is compared to the color development of standards of known concentration to determine phosphorus content.
