These data were compiled to allow examination of northern spotted owl territorial occupancy dynamics, especially with regards to the roles played by habitat and competition with barred owl in past and future dynamics. Data are estimates of parameters derived from previous modelling of northern spotted owl territorial occupancy dynamics. These data were collected as part of monitoring of northern spotted owl demography. Associated code allows analysis of these estimates to understand the roles of competition and habitat in recent northern spotted owl declines and to predict the future of northern spotted owl under various management scenarios.
A tribal block group (BG) is a cluster of census blocks having the same first digit of their four-digit identifying numbers and are within a single tribal census tract. The optimum size for a tribal BG is 1,000 people; it must contain a minimum of 300 people. The difference between a tribal BG and a nontribal BG is in the hierarchical presentation of the data. A tribal BG is part of the American Indian hierarchy; that is, the tribal BG is within a tribal census tract that is within a federally recognized American Indian reservation and/or off-reservation trust land.

Population range for each city/town. pop_1: <100 U.S. Populated Place Points represents populated places with population projected for 2030 that include census designated places, consolidated cities, and incorporated places within United States identified by the U.S. Census Bureau.
Population range for each city/town. pop_6: > 1,000,000 U.S. Populated Place Points represents populated places that include census designated places, consolidated cities, and incorporated places within United States identified by the U.S. Census Bureau.
Population range for each city/town. pop_4: 10,001 - 100,000 U.S. Populated Place Points represents populated places that include census designated places, consolidated cities, and incorporated places within United States identified by the U.S. Census Bureau.
To date, hydrological and ecological models have been developed independently from each other, making their application particularly challenging for interdisciplinary studies. The objective of this project was to synthesize and evaluate prevailing hydrological and ecological models in the South-Central U.S., particularly the southern Great Plains region. This analysis aimed to identify the data requirements and suitability of each model to simulate stream flow while addressing associated changes in the ecology of stream systems, and to portray climate variability and uncertainty. The results and deliverables of this project are expected to include a comprehensive, updated, and systematic report on recent developments...

This thematic map indicates the annual compound rate of total population change in the United States from 2000 to 2010. Total Population is the total number of residents in an area. Residence refers to the "usual place" where a person lives. Total Population for 2000 is from the U.S. Census 2000. The 2010 Total Population variable is estimated by Esri's proven a This thematic map indicates the annual compound rate of total population change in the United States from 2000 to 2010.

These data were compiled to investigate the demographic, phylogeographic, and adaptation history of Hilaria jamesii. The data release consists of three tab delimited text files that may be used to infer population structure or putative adaptive loci (hija_adaptation_dataset.stru), relationships among sampling localities (hija_phylogeny_dataset.phylip), or genetic diversity statistics (hija_diversity_stats.vcf). All files record genetic variation on an individual (.stru and .vcf) or sampling locality (.phylip) level. The .vcf file contains all of the information contained in the other files, but the file structures vary based on the programs used for analysis. These files may be opened and edited in a text editor...
This dataset was used in the Northern Great Basin Rapid Ecoregional Assessment by BLM. No changes were made to the data but the dataset selected Nevada and clipped to the ecoregion boundary.
Population range for each city/town. pop_5: 100,001 -1,000,000 U.S. Populated Place Points represents populated places with population projected for 2030 that include census designated places, consolidated cities, and incorporated places within United States identified by the U.S. Census Bureau.

In the Great Plains, climate change is expected to result in more frequent and intense droughts, severe rainfall events, and heat waves. Adapting to changing conditions will require coordination in the research and observation capabilities of multiple organizations, institutions, and government programs. In light of these needs, researchers worked with federal, state, tribal, university, and non-governmental organization partners to (1) synthesize the current state of ecosystems in the Great Plains; (2) assess the ability of human and ecological communities in the region to adapt to climate change; and (3) develop a process to improve future assessments of the vulnerability of the region’s natural and cultural resources...

This study set out to answer the question: “What data and modeling frameworks are needed to provide scientists reliable, climate-informed, water temperature estimates for freshwater ecosystems that can assist watershed management decision making?” To accomplish this, the study gathered existing stream temperature data, identified data gaps, deployed stream temperature monitoring devices, and developed and tested a stream temperature model that could be regionalized across the Northeast domain. We partnered with another funded project team, led by Jana Stewart at WI USGS to collect data from over 10,000 locations across the climate science center domain. This collection effort aided in identifying data gaps where...

We routinely encounter uncertainty when we make decisions – from picking a new morning coffee to choosing where to live. Even decisions that are supported by science contain some level of remaining uncertainty. In the context of conservation and wildlife management, the potential for uncertainty to influence decisions is perhaps most obvious when we think about predicting how actions (or non-actions) will have lasting impacts into the future. Our abilities to precisely predict future climatic and ecological conditions and determine the exact consequences of our actions are, and will remain, limited. Conservation practitioners and land and wildlife managers must navigate these challenges to make science-informed...
