Data tables summarizing the source-specific estimated water withdrawals in Florida by category, county, and water management district, 2015. Data tables summarizing the source-specific estimated water withdrawals in Florida by category, county, and water management district, 2015.
In 2015, the total amount of water withdrawn in Florida was estimated at 15,319 million gallons per day (Mgal/d). This includes 9,598 Mgal/d of saline water and 5,721 Mgal/d of fresh water. Groundwater accounted for 3,604 Mgal/d and surface water accounted for 2,117 Mgal/d of the fresh water withdrawals. Surface water accounted for 9,400 Mgal/d and groundwater 198 Mgal/d of the saline...
Arctic Shorebird Population Model Arctic Shorebird Population Model
This R script will run one example of the stochastic matrix models run by Weiser et al. (2020) to simulate shorebird populations. The model predicts population growth rates and elasticity values of vital rates. The example script is stand-alone and contains input values for one example species; input values for the other species are provided in the manuscript.
Tracking Data for Black Scoter (Melanitta americana) Tracking Data for Black Scoter (Melanitta americana)
This data release includes 2 child items with tracking data for Black Scoters, a sea duck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. Child Item 1: "Argos Satellite Tracking Data for Black Scoters (Melanitta americana) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters.
Marginalizing Bayesian population models - data for examples in the Grand Canyon region, southeastern Arizona, western Oregon USA - 1990-2015 Marginalizing Bayesian population models - data for examples in the Grand Canyon region, southeastern Arizona, western Oregon USA - 1990-2015
These data were compiled here to fit various versions of Bayesian population models and compare their performance, primarily the time required to make inferences using different softwares and versions of code. The humpback chub data were collected by US Geological Survey and US Fish and Wildlife service in the Colorado and Little Colorado Rivers from April 2009 to October 2017. Adult...
Stand density and climate data in the Taylor Woods study area (Fort Valley Experimental Forest) on the Colorado Plateau in Northern Arizona, 1961-2011 Stand density and climate data in the Taylor Woods study area (Fort Valley Experimental Forest) on the Colorado Plateau in Northern Arizona, 1961-2011
These data were compiled for research pertaining to the effects of stand density on growth rates in semi-arid forests. Increasing heat and aridity in coming decades is expected to negatively impact tree growth and threaten forest sustainability in dry areas. Maintaining low stand density has the potential to mitigate the negative effects of increasingly severe droughts by minimizing...
