Automated extraction of natural drainage density patterns for the conterminous United States through high performance computing Automated extraction of natural drainage density patterns for the conterminous United States through high performance computing
Hydrographic networks form an important data foundation for cartographic base mapping and for hydrologic analysis. Drainage density patterns for these networks can be derived to characterize local landscape, bedrock and climate conditions, and further inform hydrologic and geomorphological analysis by indicating areas where too few headwater channels have been extracted. But natural...

Changes in data sharing and data reuse practices and perceptions among scientists worldwide Changes in data sharing and data reuse practices and perceptions among scientists worldwide
The incorporation of data sharing into the research lifecycle is an important part of modern scholarly debate. In this study, the DataONE Usability and Assessment working group addresses two primary goals: To examine the current state of data sharing and reuse perceptions and practices among research scientists as they compare to the 2009/2010 baseline study, and to examine differences...

U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2014 annual report U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2014 annual report
This is the seventh report produced by the U.S. Geological Survey (USGS) for the Wyoming Landscape Conservation Initiative (WLCI) to detail annual activities conducted by the USGS for addressing specific management needs identified by WLCI partners. In FY2014, there were 26 projects, including a new one that was completed, two others that were also completed, and several that entered new...

Linking state-and-transition simulation and timber supply models for forest biomass production scenarios Linking state-and-transition simulation and timber supply models for forest biomass production scenarios
We linked state-and-transition simulation models (STSMs) with an economics-based timber supply model to examine landscape dynamics in North Carolina through 2050 for three scenarios of forest biomass production. Forest biomass could be an important source of renewable energy in the future, but there is currently much uncertainty about how biomass production would impact landscapes. In...

Running a network on a shoestring: the Global Invasive Species Information Network Running a network on a shoestring: the Global Invasive Species Information Network
The Global Invasive Species Information Network (GISIN) was conceptualized in 2004 to aggregate and disseminate invasive species data in a standardized way. A decade later the GISIN community has implemented a data portal and three of six GISIN data aggregation models in the GISIN data exchange Protocol, including invasive species status information, resource URLs, and occurrence data...

How a national vegetation classification can help ecological research and management How a national vegetation classification can help ecological research and management
The elegance of classification lies in its ability to compile and systematize various terminological conventions and masses of information that are unattainable during typical research projects. Imagine a discipline without standards for collection, analysis, and interpretation; unfortunately, that describes much of 20th-century vegetation ecology. With differing methods, how do we...

The fourth volume of the comprehensive history of the U.S. Geological Survey (USGS) is titled “Minerals, Lands, and Geology for the Common Defence and General Welfare—Volume 4, 1939‒1961.” The title is based on a passage in the preamble of the U.S. Constitution. The late Mary C. Rabbitt (1915‒2002), a geophysicist who served with the U.S. Coast and Geodetic Survey (1948‒1949) and the...

A case study of data integration for aquatic resources using semantic web technologies A case study of data integration for aquatic resources using semantic web technologies
Use cases, information modeling, and linked data techniques are Semantic Web technologies used to develop a prototype system that integrates scientific observations from four independent USGS and cooperator data systems. The techniques were tested with a use case goal of creating a data set for use in exploring potential relationships among freshwater fish populations and environmental...

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
