Data from: Temporal population genetic instability in range edge Western Toads, Anaxyrus boreas
In this article, we address the temporal stability of population genetic structure in a range-edge population that is undergoing continual, short-distance colonization events. We sampled western toad, Anaxyrus boreas, breeding populations over 2 seasons near their northern range limit in southeast Alaska. We sampled 20 ponds each during the summers of 2008 and 2009, with 14 ponds sampled in both summers. We found considerable turnover in the population genetic relationships among ponds in those 2 seasons, as well as biologically meaningful genetic differentiation between years within some ponds. We found relatively consistent relationships between major population centers, whereas the relationships between the central ponds and smaller, outlying populations differed year to year. This finding indicates that multiple years of genetic sampling may be important for understanding the genetic landscape of some populations.

FIG. 3 in Few Impacts of Introduced Cutthroat Trout (Oncorhynchus clarki) on Aquatic Stages of Boreal Toads (Anaxyrus boreas boreas)
FIG. 3. Estimated relationships between Cutthroat Trout habitat use and water depth (a), vegetation density (b), and temperature (c) by using the most parsimonious occupancy model, Ψ(size + depth + veg + temp), p(.), during the embryo stage of Boreal Toad development. Relationships with each covariate is plotted using the average values of other covariates. The dashed line designates the relationship for small Cutthroat Trout, and the solid line represents the relationships for large Cutthroat Trout. Shaded areas represent 95% confidence intervals. In (a) and (b), the circles indicate the vegetation density and predicted use at the three egg mass locations. In (c), the squares indicate the average morning temperatures and predicted use at the three egg mass locations. The triangles represent the same for the average evening temperatures.

BOREAS TF-08 NSA-OJP and SSA-OBS Ceilometer Data
The BOREAS TF-08 team used ceilometers to collect data on the fraction of the sky covered with clouds and the cloud height. Included with these data is the surface-based lifting condensation level, derived from temperature and humidity values acquired at the flux tower at the NSA-OJP site. Ceilometer data were collected at the NSA-OJP site in 1994 and at the NSA-OJP and SSA-OBS sites in 1996.
BOREAS TE-10 Photosynthetic Response Data
The BOREAS TE-10 team collected several data sets in support of its efforts to characterize and interpret information on the gas exchange, reflectance, transmittance, chlorophyll content, carbon content, hydrogen content, nitrogen content, and photosynthetic response of boreal vegetation. This data set contains measurements of quantitative parameters and leaf photosynthetic response to increases in light conducted in the SSA during the growing seasons of 1994 and 1996 using an oxygen electrode system. Leaf photosynthetic responses were not collected in 1996.
BOREAS AFM-06 Mean Wind Profile Data
The BOREAS AFM-06 team from the National Oceanic and Atmospheric Administration Environment Technology Laboratory (NOAA/ETL) operated a 915 MHz wind/Radio Acoustic Sounding System (RASS) profiler system in the Southern Study Area (SSA) near the Old Jack Pine (OJP) tower from 21-May-1994 to 20-Sep-1994. The data set provides wind profiles at 38 heights, containing the variables of wind speed, wind direction and the u-, v-, and w-components of the total wind.
BOREAS Daedalus TMS Level-0 Imagery: Digital Counts in BIL Format
The level-0 Daedalus TMS imagery, along with the other remotely sensed images, was collected to provide spatially extensive information about radiant energy over the primary BOREAS study areas. This information includes detailed land cover and biophysical parameter maps such as FPAR and LAI. Two flights of the Daedalus TMS instrument were made onboard the ER-2 aircraft on September 16 and 17, 1994. Companion files include (1) an image inventory listing to inform users of the images that are available and (2) example thumbnail images that may be viewed and the image data files downloaded using a convenient viewer utility.
BOREAS TE-06 Predawn Leaf Water Potentials and Foliage Moisture Content Data
The BOREAS TE-06 team collected several data sets to examine the influence of vegetation, climate, and their interactions on the major carbon fluxes for boreal forest species. This data set contains summaries of predawn leaf water potentials and foliage moisture contents collected at the TF and CEV sites that had canopy access towers. The data was collected on a nearly weekly basis from early June to late August 1994 by TE-06, members of the BOREAS staff, and employees of Environment Canada.
BOREAS TE-17 Production Efficiency Model Images
A BOREAS version of the Global Production Efficiency Model (www.inform.umd.edu/glopem) was developed by TE-17 to generate maps of gross and net primary production, autotrophic respiration, and light use efficiency for the BOREAS region. This document provides basic information on the model and how the maps were generated. The data generated by the model are stored in binary image-format files.
BOREAS TF-08 NSA-OJP Tower Flux, Meteorological, and Soil Temperature Data
The BOREAS TF-08 team collected energy, CO2, and water vapor flux data at the BOREAS NSA-OJP site during the growing season of 1994 and most of the year for 1996.
BOREAS HYD-08 1996 Gravimetric Moss Moisture Data
The BOREAS HYD-08 team made measurements of surface hydrological processes that were collected at the SSA-OBS Tower Flux site in 1996 to support its research into point hydrological processes and the spatial variation of these processes. Data collected may be useful in characterizing canopy interception, drip, throughfall, moss interception, drainage, evaporation, and capacity during the growing season at daily temporal resolution. This particular data set contains the gravimetric moss moisture measurements from July to August 1996. To collect these data, a nested spatial sampling plan was implemented to support research into spatial variations of the measured hydrological processes and ultimately the impact of these variations on modeled carbon and water budgets.
BOREAS RSS-03 Reflectance Measured from a Helicopter-Mounted SE-590
The BOREAS RSS-03 team collected multiple remotely sensed data sets from the NASA UH-1 helicopter. This data set includes helicopter-based radiometric measurements of forested sites acquired during BOREAS made with an SE-590 processed to reflectance factors. The data used in this analysis were collected in 1994 during the three BOREAS IFCs at numerous tower and auxiliary sites in both the NSA and the SSA. The 15-degree FOV of the SE-590 yielded a ground resolution of approximately 79 m at the 300-m nominal altitude.
