The Large River Monitoring Forum compiled fish assemblage data for five large rivers in the U.S. as a part of a coordinated effort to compare and contract river monitoring efforts in large river systems. Fish community data from five monitoring programs were integrated to create the standardized dataset. Authors: Timothy D. Counihan1, Ian R.

The Southern Megalopolis: Using the Past to Predict the Future of Urban Sprawl in the Southeast U.S.
Abstract (from http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0102261): The future health of ecosystems is arguably as dependent on urban sprawl as it is on human-caused climatic warming. Urban sprawl strongly impacts the urban ecosystems it creates and the natural and agro-ecosystems that it displaces and fragments. Here, we project urban sprawl changes for the next 50 years for the fast-growing Southeast U.S. Previous studies have focused on modeling population density, but the urban extent is arguably as important as population density per se in terms of its ecological and conservation impacts. We develop simulations using the SLEUTH urban growth model that complement population-driven models...

Processing constraints made it impractical to model the species habitat distributions across the full conterminous U.S. in one model. The modeling regions were used to stratify the conterminous U.S. into modeling extents that could be efficiently used in our workflow. The regions were based on grouping of the map zones developed for the National Land Cover Dataset production and were designed to partition the full extent into the minimal number of regions while maximizing the homogeneity of habitats within a region. Two versions of each modeling region were created one in which a buffer was applied to remove boundary issues when calculating metrics based on neighborhoods, and a version used to clip the final model...
