Principal components of climate variation in the Desert Southwest for the future time period 2040-2070 (RCP 8.5) Five principal components are used to represent the climate variation in an original set of 12 composite climate variables reflecting complex precipitation and temperature gradients. The dataset provides coverage for future climate (defined as the 2040-2070 normal period) under the RCP8.5 emission scenarios. Climate variables were chosen based on their known influence on local adaptation in plants, and include: mean annual temperature, summer maximum temperature, winter minimum temperature, annual temperature range, temperature seasonality (coefficient of variation in monthly average temperatures), mean annual precipitation, winter precipitation, summer precipitation, proportion of summer precipitation, precipitation...

Surveys were conducted at 378 plots. Plots were surveyed twice in 2021 and the number, age (adult or juvenile), banding status (color banded or not), and breeding status (paired, unpaired, or unknown) of all wrens recorded. Habitat covariate data were collected including amount of dead and stressed cactus in the plot, percent cover of bare ground, and the dominant and percent cover of invasive species.

The USGS spring range-wide sea otter census has been undertaken each year since 1982, using consistent methodology involving both ground-based and aerial-based counts. The spring census provides the primary basis for gauging population trends by State and Federal management agencies.

Data for the post-fire study were collected in 2015, 2016, and 2020, while the regional occupancy survey was conducted in 2016, and 2020. In 2015, gnatcatcher occupancy as a function of fire history was derived from 324 points in the following fire categories: 2003-2006 (106 points), 2007-2010 (111 points), and 2011-2014 (107 points).

Eggshell thickness was related to egg morphometrics (egg length and width), embryonic development, egg status, and mercury contamination. Individual eggshells each have up to 3 thickness measurements, linked by the eggshell identification. Each measurement has the corresponding egg length, egg width, egg status, mercury concentration, and nest identification. Additionally, eggshell thickness was measured at 5 equally spaced positions along the longitude of the egg (sharp pole, quarter egg, half egg, three quarter egg, and blunt pole) in a subset of Forster's tern (Sterna forsteri) eggs.

Fitting these hindcasts to observed height and periods indicates that the hindcasts have consistent biases that can be corrected for statistically. Past work generated bias corrections for 32 sites in the Channel Islands. We use these bias corrections to correct hourly height and period hindcasts at these sites from 2000 to 2017.
