Bryan D. Downing, Brian A. Bergamaschi, Carol Kendall, Tamara E. C. Kraus, Kate J. Dennis, Jeffery A. Carter, Travis von Dessonneck
2016, Environmental Science & Technology (50) 13387-13396
Stable isotopes present in water (δ2H, δ18O) have been used extensively to evaluate hydrological processes on the basis of parameters such as evaporation, precipitation, mixing, and residence time. In estuarine aquatic habitats, residence time (τ) is a major driver of biogeochemical processes, affecting trophic subsidies and conditions in fish-spawning habitats....

Paektu volcano (Changbaishan) is a rhyolitic caldera that straddles the border between the Democratic People's Republic of Korea (DPRK) and China. Its most recent large eruption was the Millennium Eruption (ME; 23 km3 DRE) circa 946 CE, which resulted in the release of copious magmatic volatiles (H2O, CO2, sulfur, and...

Cindy A. Thatcher, Samsung Lim, Monica Palaseanu-Lovejoy, Jeffrey J. Danielson, Dustin R. Kimbrow
2016, International Journal of Remote Sensing (37) 5708-5725
Flood protection in south Louisiana is largely dependent on earthen levees, and in the aftermath of Hurricane Katrina the state’s levee system has received intense scrutiny. Accurate elevation data along the levees are critical to local levee district managers responsible for monitoring and maintaining the extensive system of non-federal levees...

Aqueous exposure to the progestin, levonorgestrel, alters anal fin development and reproductive behavior in the eastern mosquitofish (Gambusia holbrooki)
Tyler E. Frankel, Michael T. Meyer, Edward F. Orlando
2016, General and Comparative Endocrinology (234) 161-169
Endogenous progestogens are important regulators of vertebrate reproduction. Synthetic progestins are components of human contraceptive and hormone replacement pharmaceuticals. Both progestogens and progestins enter the environment through a number of sources, and have been shown to cause profound effects on reproductive health in various aquatic vertebrates. Progestins are designed to...
Vive la résistance: genome-wide selection against introduced alleles in invasive hybrid zones

2016, Proceedings of the Royal Society B: Biological Sciences (283)
Evolutionary and ecological consequences of hybridization between native and invasive species are notoriously complicated because patterns of selection acting on non-native alleles can vary throughout the genome and across environments. Rapid advances in genomics now make it feasible to assess locus-specific and genome-wide patterns of natural selection acting on invasive...
Was everything bigger in Texas? Characterization and trends of a land-based recreational shark fishery
Matthew J. Ajemian, Philip D. Jose, John T. Froeschke, Mark L. Wildhaber, Gregory W. Stunz
2016, Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science (8) 553-566
Although current assessments of shark population trends involve both fishery-independent and fishery-dependent data, the latter are generally limited to commercial landings that may neglect nearshore coastal habitats. Texas has supported the longest organized land-based recreational shark fishery in the United States, yet no studies have used this “non-traditional” data source...

2016, Canadian Journal of Forest Research (47) 113-124
High-resolution site index (SI) and mean annual increment (MAI) maps are desired for local forest management. We integrated field inventory, Landsat, and ecological variables to produce 30 m SI and MAI maps for the Tahoe National Forest (TNF) where different tree species coexist. We converted species-specific SI using adjustment factors....

Brian K. Breaker, Kara M. Watson, Paul A. Ensminger, John B. Storm, Claire E. Rose
2016, Scientific Investigations Report 2016-5162
Heavy rainfall occurred across Louisiana, Texas, Arkansas, and Mississippi in March 2016 as a result of a slow-moving southward dip in the jetstream, funneling tropical moisture into parts of the Gulf Coast States and the Mississippi River Valley. The storm caused major flooding in the northwestern and southeastern parts of...
Processes of multibathyal aragonite undersaturation in the Arctic Ocean
J.G. Wynn, L. L. Robbins, L.G. Anderson
2016, Journal of Geophysical Research: Oceans (121) 8248-8267
During 3 years of study (2010–2012), the western Arctic Ocean was found to have unique aragonite saturation profiles with up to three distinct aragonite undersaturation zones. This complexity is produced as inflow of Atlantic-derived and Pacific-derived water masses mix with Arctic-derived waters, which are further modified by physiochemical and biological...
Management implications of brood division in Golden-winged Warblers
Sean M. Peterson, Henry M. Streby, David E. Andersen
2016, Book chapter, Golden-winged Warbler ecology, conservation, and habitat management (Studies in Avian Biology, volume 49)
Brood division in the postfledging period is a common avian behavior that is not well understood. Brood division has been reported in Golden-winged Warblers (Vermivora chrysoptera), but it is not known how common this behavior is, whether males and females exhibit different strategies related to parental care and habitat use,...

2016, Scientific Investigations Report 2016-5134
In 2012, the U.S. Geological Survey, in cooperation with the Arkansas River Basin Regional Resource Planning Group, initiated a study of groundwater and surface-water interaction, water quality, and loading of dissolved solids, selenium, and uranium to Fountain Creek near Pueblo, Colorado, to improve understanding of sources and processes affecting loading...
Is the geographic range of mangrove forests in the conterminous United States really expanding?
Chandra Giri, Jordan Long
2016, Sensors (16)
Changes in the distribution and abundance of mangrove species within and outside of their historic geographic range can have profound consequences in the provision of ecosystem goods and services they provide. Mangroves in the conterminous United States (CONUS) are believed to be expanding poleward (north) due to decreases in...
