Tree regeneration by seed in bottomland hardwood forests: A review
Whitney A. Kroschel, Sammy L. King, Richard F. Keim
2016, Southeastern Naturalist (15) 42-60
Bottomland hardwood forests (BLH) are found in temperate, humid regions of the southeastern US, primarily on alluvial floodplains adjacent to rivers. Altered hydrology in rivers and floodplains has caused changes in stand development and species composition of BLHs. We hypothesize that the driving mechanisms behind these changes are related to...
Accurate recapture identification for genetic mark–recapture studies with error-tolerant likelihood-based match calling and sample clustering
Suresh Sethi, Daniel Linden, John Wenburg, Cara Lewis, Patrick R. Lemons, Angela K. Fuller, Matthew P. Hare
2016, Royal Society Open Science (3) 1-14
Error-tolerant likelihood-based match calling presents a promising technique to accurately identify recapture events in genetic mark–recapture studies by combining probabilities of latent genotypes and probabilities of observed genotypes, which may contain genotyping errors. Combined with clustering algorithms to group samples into sets of recaptures based upon pairwise match calls, these...

Kurt J. Jenkins, Patricia J. Happe, Katherine F. Beirne, William T. Baccus
2016, Open-File Report 2016-1185
Executive SummaryWe estimated abundance and trends of non-native mountain goats (Oreamnos americanus) in the Olympic Mountains of northwestern Washington, based on aerial surveys conducted during July 13–24, 2016. The surveys produced the seventh population estimate since the first formal aerial surveys were conducted in 1983. This was the second population...
Lidar-based mapping of flood control levees in south Louisiana
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...

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...
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...
Vive la résistance: genome-wide selection against introduced alleles in invasive hybrid zones
Ryan P. Kovach, Brian K. Hand, Paul A. Hohenlohe, Ted F. Cosart, Matthew C. Boyer, Helen H. Neville, Clint C. Muhlfeld, Stephen J. Amish, Kellie Carim, Shawn R. Narum, Winsor H. Lowe, Fred W. Allendorf, Gordon Luikart
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...

Rui Chen, Kishor S. Jaiswal, D Bausch, H Seligson, C.J. Wills
2016, Seismological Research Letters (87) 1363-1372
Input datasets for annualized earthquake loss (AEL) estimation for California were updated recently by the scientific community, and include the National Seismic Hazard Model (NSHM), site‐response model, and estimates of shear‐wave velocity. Additionally, the Federal Emergency Management Agency’s loss estimation tool, Hazus, was updated to include the most recent census...
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...

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...

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,...

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...

Sparkle Malone, Mirela Tulbure, Antonio J. Perez-Luque, Timothy J. Assal, Leah Bremer, Debora Drucker, Vicken Hillis, Sara Varela, Michael Goulden
2016, Ecosphere (7)
Drought is a global issue that is exacerbated by climate change and increasing anthropogenic water demands. The recent occurrence of drought in California provides an important opportunity to examine drought response across ecosystem classes (forests, shrublands, grasslands, and wetlands), which is essential to understand how climate influences ecosystem structure and...
