INVASIVESNET towards an International Association for Open Knowledge on Invasive Alien Species INVASIVESNET towards an International Association for Open Knowledge on Invasive Alien Species
In a world where invasive alien species (IAS) are recognised as one of the major threats to biodiversity, leading scientists from five continents have come together to propose the concept of developing an international association for open knowledge and open data on IAS—termed “INVASIVESNET”. This new association will facilitate greater understanding and improved management of invasive...

Making it and breaking it in the Midwest: Continental assembly and rifting from modeling of EarthScope magnetotelluric data Making it and breaking it in the Midwest: Continental assembly and rifting from modeling of EarthScope magnetotelluric data
A three-dimensional lithospheric-scale resistivity model of the North American mid-continent has been estimated based upon EarthScope magnetotelluric data. Details of the resistivity model are discussed in relation to lithospheric sutures, defined primarily from aeromagnetic and geochronologic data, which record the southward growth of the Laurentian margin in the Proterozoic. The...

Normalized burn ratios link fire severity with patterns of avian occurrence Normalized burn ratios link fire severity with patterns of avian occurrence
Context Remotely sensed differenced normalized burn ratios (DNBR) provide an index of fire severity across the footprint of a fire. We asked whether this index was useful for explaining patterns of bird occurrence within fire adapted xeric pine-oak forests of the southern Appalachian Mountains.Objectives We evaluated the use of DNBR indices for linking ecosystem process with patterns of...

A comparison of NLCD 2011 and LANDFIRE EVT 2010: Regional and national summaries. A comparison of NLCD 2011 and LANDFIRE EVT 2010: Regional and national summaries.
In order to provide the land cover user community a summary of the similarity and differences between the 2011 National Land Cover Dataset (NLCD) and the Landscape Fire and Resource Management Planning Tools Program Existing Vegetation 2010 Data (LANDFIRE EVT), the two datasets were compared at a national (conterminous U.S.) and regional (Eastern, Midwestern, and Western) extents (Figure...

Community for Data Integration 2014 annual report Community for Data Integration 2014 annual report
The U.S. Geological Survey (USGS) researches 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...

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...

Mapping the 3-D extent of the Northern Lobe of the Bushveld layered mafic intrusion from geophysical data Mapping the 3-D extent of the Northern Lobe of the Bushveld layered mafic intrusion from geophysical data
Geophysical models image the 3D geometry of the mafic portion of the Bushveld Complex north of the Thabazimbi-Murchison Lineament (TML), critical for understanding the origin of the world's largest layered mafic intrusion and platinum group element deposits. The combination of the gravity and magnetic data with recent seismic, MT, borehole and rock property measurements powerfully...

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...
