Community for Data Integration 2013 Annual Report Community for Data Integration 2013 Annual Report
The U.S. Geological Survey (USGS) conducts earth science to help address complex issues affecting society and the environment. In 2006, the USGS held the first Scientific Information Management Workshop to bring together staff from across the organization to discuss the data and information management issues affecting the integration and delivery of earth science research and investigate...

Modeling climate change, urbanization, and fire effects on Pinus palustris ecosystems of the southeastern U.S. Modeling climate change, urbanization, and fire effects on Pinus palustris ecosystems of the southeastern U.S.
Managing ecosystems for resilience and sustainability requires understanding how they will respond to future anthropogenic drivers such as climate change and urbanization. In fire-dependent ecosystems, predicting this response requires a focus on how these drivers will impact fire regimes. Here, we use scenarios of climate change, urbanization and management to simulate the future...

Distribution and floral hosts of Anthophorula micheneri ( Timberlake, 1947) and Hylaeus sparsus (Cresson, 1869), (Insecta: Hymenoptera: Apoidea: Anthophila), with new staterecords in Giles and Loudoun counties, Virginia, eastern USA Distribution and floral hosts of Anthophorula micheneri ( Timberlake, 1947) and Hylaeus sparsus (Cresson, 1869), (Insecta: Hymenoptera: Apoidea: Anthophila), with new staterecords in Giles and Loudoun counties, Virginia, eastern USA
New collection records for Anthophorula micheneri (Timberlake, 1947) from Loudoun County and other locations in Virginia, USA document an approximately 1,350 km extension of its previously recorded geographic range. New state records for the rarely seen Hylaeus sparsus (Cresson, 1869) collected in Giles County and from a blue vane trap in Loudoun County, Virginia add to our knowledge of...

Robust estimates of environmental effects on population vital rates: an integrated capture–recapture model of seasonal brook trout growth, survival and movement in a stream network Robust estimates of environmental effects on population vital rates: an integrated capture–recapture model of seasonal brook trout growth, survival and movement in a stream network
Modelling the effects of environmental change on populations is a key challenge for ecologists, particularly as the pace of change increases. Currently, modelling efforts are limited by difficulties in establishing robust relationships between environmental drivers and population responses.We developed an integrated capture–recapture state-space model to estimate the effects of two key

DigitalCrust – a 4D data system of material properties for transforming research on crustal fluid flow DigitalCrust – a 4D data system of material properties for transforming research on crustal fluid flow
Fluid circulation in the Earth's crust plays an essential role in surface, near surface, and deep crustal processes. Flow pathways are driven by hydraulic gradients but controlled by material permeability, which varies over many orders of magnitude and changes over time. Although millions of measurements of crustal properties have been made, including geophysical imaging and borehole...

Future land-use scenarios and the loss of wildlife habitats in the southeastern United States Future land-use scenarios and the loss of wildlife habitats in the southeastern United States
Land-use change is a major cause of wildlife habitat loss. Understanding how changes in land-use policies and economic factors can impact future trends in land use and wildlife habitat loss is therefore critical for conservation efforts. Our goal here was to evaluate the consequences of future land-use changes under different conservation policies and crop market conditions on habitat...

Research data services in academic libraries: Data intensive roles for the future? Research data services in academic libraries: Data intensive roles for the future?
Objectives: The primary objectives of this study are to gauge the various levels of Research Data Service academic libraries provide based on demographic factors, gauging RDS growth since 2011, and what obstacles may prevent expansion or growth of services. Methods: Survey of academic institutions through stratified random sample of ACRL library directors across the U.S. and Canada...

Predicting occupancy for pygmy rabbits in Wyoming: an independent evaluation of two species distribution models Predicting occupancy for pygmy rabbits in Wyoming: an independent evaluation of two species distribution models
Species distribution models are an important component of natural-resource conservation planning efforts. Independent, external evaluation of their accuracy is important before they are used in management contexts. We evaluated the classification accuracy of two species distribution models designed to predict the distribution of pygmy rabbit Brachylagus idahoensis habitat in southwestern...

Influence of nonnative and native ungulate biomass and seasonal precipitation on vegetation production in a Great Basin ecosystem Influence of nonnative and native ungulate biomass and seasonal precipitation on vegetation production in a Great Basin ecosystem
The negative effects of equid grazers in semiarid ecosystems of the American West have been considered disproportionate to the influence of native ungulates in these systems because of equids' large body size, hoof shape, and short history on the landscape relative to native ungulates. Tools that can analyze the degree of influence of various ungulate herbivores in an ecosystem and...

Two decision-support tools for assessing the potential effects of energy development on hydrologic resources as part of the Energy and Environment in the Rocky Mountain Area interactive energy atlas Two decision-support tools for assessing the potential effects of energy development on hydrologic resources as part of the Energy and Environment in the Rocky Mountain Area interactive energy atlas
The U.S. Geological Survey project—Energy and Environment in the Rocky Mountain Area (EERMA)—has developed a set of virtual tools in the form of an online interactive energy atlas for Colorado and New Mexico to facilitate access to geospatial data related to energy resources, energy infrastructure, and natural resources that may be affected by energy development. The interactive energy...
