Abstract for the dataset - REQUIRED Chapter 2: The datasets are elemental concentrations for 25 elements from samples of the saxicolous lichens Umbilicaria phaea (n = 51), Rhizoplaca melanophthalma (n = 20), and the epiphytic lichen Letharia vulpina (n = 16) from the southern Sierra Nevada and San Bernardino Mountains of California. Lichen samples were collected between 2013 and 2019 at 31 plots between 180 and 3330 m of elevation. There are accompanying data of environmental variables. Chapter 3: The datasets are epiphytic lichen community data from 52 plots from central California and a simulated dataset with known underlying determinants of community structure. There are accompanying data of environmental variables. 3. Date of data collection: 1998-2021 4. Geographic location of data collection: Southern Sierra Nevadas and San Bernardino mountains of California, USA 5.

Was data derived from another source? Yes http://gis.nacse.org/lichenair/ -------------------------- METHODOLOGICAL INFORMATION - REQUIRED -------------------------- 1. Description of methods used for collection/generation of data: Chapter 2: All lichens were collected using powder free nitrile gloves and SpeciPAK saran bags. Six or more different rocks/woody substrata were sampled up to a few hundred meters away from the center of the plot. Lichens were removed from the rock using a ceramic scalpel allowing for collection of whole specimens. Chapter 3: The plots are circular with a radius of 114 feet and an area of 0.379 hectares. Every macrolichen species found above a half meter on wood as well as in the litterfall was collected on the plots over the course of two hours or less. Each species was assigned a pseudo-logarithmic abundance rating in each plot: 1 = one to three individuals, 2 = four to 10 individuals, 3 = greater than 10 individuals, but present on less than half of allowable substrate, and 4 = more than 10 individuals and present on at least half of allowable substrate. Elevation, total basal area, conifer and hardwood basal area, and percent conifer/hardwood were recorded when the plots were visited. 2. Methods for processing the data: Chapter 2: Lichens were cleaned while wearing powder free nitrile gloves using equipment cleaned with 70% ethanol. Debris, diseased portions of the thalli, and other lichen species are removed. After cleaning, a subset of samples that didn’t have a plot repeat were divided in half into “splits” to measure within sample variability. Lichens were dried for 24 hours at 70 °C, ground, and then microwave digested. After digestion samples were analyzed for 25 elements using a Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) and a combustion analyzer. Certified reference lichen materials (IAEA-336 Evernia) were analyzed with the lichen samples. 5. Environmental/experimental conditions: Chapter 2 and 3: Three year rolling averages of modeled N deposition estimates come from the Community Multiscale Air Quality model v. 5.0.2 and the Total Deposition model v. 2018.02. Thirty-year climate normals for environmental variables were extracted from the Parameter-elevation Regressions on Independent Slopes Model. --------------------- DATA & FILE OVERVIEW - REQUIRED --------------------- See DataDictionary.pdf ----------------------------------------- TABULAR DATA-SPECIFIC INFORMATION FOR: ALL FILES ----------------------------------------- See DataDictionary.pdf
