USGS DISCOVRE: Benthic Ecology, Trophodynamics, and Ecosystem Connectivity – Lophelia II: Continuing Ecological Research on Deep-Sea Corals and Deep Reef Habitats in the Gulf of Mexico
Deep-sea coral habitats are complex ecosystems at the landscape and local level. While these systems may harbor substantial levels of biodiversity, they remain inadequately investigated.
Wetland restoration and creation efforts are increasingly proposed as means to compensate for wetland losses. To address the need for evaluating the development of ecosystem structure and function in restored and created wetlands, USGS compared created tidal wetlands sites to natural mangrove wetlands in Tampa Bay, Florida.
In support of Louisiana’s 2012 Coastal Master Plan, USGS WARC scientists have developed a spatially explicit wetland morphology model and coupled it with other predictive models to help predict the effects of protection and restoration projects.
USGS WARC first implemented geographic information systems (GIS) in 1980 to assist in monitoring the nature and extent of wetland habitat changes. Today, geographers and support staff create, maintain, and use geospatial data to analyze restoration efforts in Louisiana.

Do open access data policies inhibit innovation?
There has been a great deal of attention paid recently to the idea of data sharing (Van Noorden 2014, Beardsley 2015, Nature Publishing Group2015, www.copdess.com). However, the vast majority of these arguments are in agreement and present as fait accompli the idea that data are a public good and that therefore, once...Katzner, Todd E.
Efforts to eradicate yellow crazy ants on Johnston Atoll: Results from Crazy Ant Strike Team IX, December 2014-June 2015
The ecologically destructive yellow crazy ant (YCA; Anoplolepis gracilipes) was first detected on Johnston Atoll in January 2010. Within eight months, the U.S. Fish and Wildlife Service had mobilized its first crazy ant strike team (CAST), a group of biologists dedicated to testing and identifying insecticidal baits to be used to eradicate the ant...Banko, Paul C.; Peck, Robert W.; Donmoyer, Kevin; Kropidlowski, Stephan; Pollock, Amanda
Polymorphic mountain whitefish (Prosopium williamsoni) in a coastal riverscape: size class assemblages, distribution, and habitat associations
We compared the assemblage structure, spatial distributions, and habitat associations of mountain whitefish (Prosopium williamsoni) morphotypes and size classes. We hypothesised that morphotypes would have different spatial distributions and would be associated with different habitat features based on feeding behaviour and diet. Spatially...Starr, James C.; Torgersen, Christian E.
Will a warmer and wetter future cause extinction of native Hawaiian forest birds?
Isolation of the Hawaiian archipelago produced a highly endemic and unique avifauna. Avian malaria (Plasmodium relictum), an introduced mosquito-borne pathogen, is a primary cause of extinctions and declines of these endemic honeycreepers. Our research assesses how global climate change will affect future malaria risk and native bird populations....Liao, Wei; Timm, Oliver Elison; Zhang, Chunxi; Atkinson, Carter T.; LaPointe, Dennis; Samuel, Michael D.
Molecular tracing of confiscated pangolin scales for conservation and illegal trade monitoring in Southeast Asia
