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) nodule biomass. 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 2015.

Data Table Name:
744_nodule_biomass_2015.csv
Description:
This dataset contains nodule biomass information for Siberian alders (Alnus viridis ssp. fruticosa) sampled in 2015 on study plots that were sampled for nitrogen fixation in 2015 (re: nitfix_2015.csv); Boundary Fire (n=19) and Wickersham Dome Fire (n=21). Study plots were a part of the relevel study plot sample from 2014 (re: releve_plots_2014.csv). Live and dead nodule biomass were estimated from soil core samples around several plants on each study plot, and the sample weights were categorized by nodule size class. 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: Between July 30th and September 28th, 2015, plant-level live nodule biomass (g nodule m-2 plant-1) was sampled at each plot that had been sampled for N-fixation [BF (n = 19), WDF (n = 21)]. At each plot, we systematically selected five alders of representative height and vigor that were not previously sampled for nodule-level N-fixation rate [BF (n = 95 alders), WDF (n = 105 alders)]. Below each alder five random soil cores (5.5 cm diameter) were collected within the area of nodulation - an area we defined as a 1 m buffer around the perimeter of the outermost ramets of an individual alder. Each soil core included the entire organic horizon and the upper 5 cm of mineral horizon. LAB: Cores from a single alder were pooled and plant-level live nodule biomass was calculated in the lab using established methods. The plant-level live nodule biomass values were then averaged at each plot for a plot-level estimate of plant-level live nodule biomass.
