Science foundation Chapter 5 Appendix 5.1: Case study Forester's tern (Sterna forsteri) and California least tern (Sternula antillarum browni)
Joshua T. Ackerman, C. Alex Hartman, Cheryl Strong
2015, Report, The baylands and climate change what we can do: Baylands ecosystem habitat goals science update 2015
This case study considers two tern species that breed within the San Francisco Bay Estuary, Forster’s Terns (Sterna forsteri) and California Least Terns (Sternula antillarum browni). Forster’s Terns are medium-sized (140 g) terns that breed in coastal and interior marshes of North America. Forster’s Terns can exploit ephemeral habitats, and...

2015, Natural Resource Report NPS/BELA/NRR—2015/1019
Serpentine Hot Springs is the most visited site in the Bering Land Bridge National Preserve. The hot springs have traditionally been used by the Native people of the Seward Peninsula for religious, medicinal and spiritual purposes and continue to be used in many of the same ways by Native people...
Isotopic insights into biological regulation of zinc in contaminated systems
Richard B. Wanty, Laurie S. Balistrieri, Jeff S. Wesner, David Walters, Travis S. Schmidt, Francesca Podda, G. De Giudici, Craig A. Stricker, Johanna M. Kraus, Pierfranco Lattanzi, Ruth E. Wolf, R. Cidu
2015, Procedia Earth and Planetary Science (13) 60-63
Aquatic organisms use a variety of biogeochemical reactions to regulate essential and non-essential trace metals. Many of these mechanisms can lead to isotopic fractionation, thus measurement of metal isotopes may yield insights into the processes by which organisms respond to metal exposure. We illustrate these concepts with two case studies,...
Science foundation Chapter 5 Appendix 5.1: Case study shore birds: Western sandpipers (Calidris mauri) and American avocets (Recurvirostra Americana)
Cheryl Strong, Joshua T. Ackerman
2015, Report, The baylands and climate change what we can do: Baylands ecosystem habitat goals science update 2015
Western sandpipers (Calidris mauri) are small (22-35 g) sexually dimorphic sandpipers, with males typically smaller than females. Western sandpipers frequently occur in mixed species flocks along with other Calidris species, including least sandpipers (Calidris minutilla) and dunlin (Calidris alpina), in the San Francisco Bay Estuary (SFBE) and are the most...

Cory T. Overton, Julian Wood
2015, Report, The baylands and climate change what we can do: Baylands ecosystem habitat goals science update 2015
The clapper rail (Rallus longirostris) recently was split into two sister groups (Chesser et al. 2014) on the basis of phylogenetic analyses (Maley and Brumfield 2013). The original grouping is now represented on the East Coast of North America by the Clapper rail (Rallus crepitans) and on the West Coast...

J. F. Taylor, T. J. Allen, John E. Repetski, J. V. Strauss, S. J. Irwin
2015, Stratigraphy (12) 71-77
As the most fossiliferous and least deformed succession of unequivocally Laurentian lower Paleozoic strata in Alaska, the Jones Ridge Limestone has provided critical data for numerous stratigraphic studies (e. g. Palmer 1968; Harris et al. 1995; Dumoulin et al. 2002; Dumoulin and Harris 2012) focused on the Cambrian and Ordovician...

Matthew J. Bunkers, Melissa Smith, Daniel G. Driscoll, Galen K. Hoogestraat
2015, Internal Report 2015-01
A group of thunderstorms produced >4 in of rain during four periods of progressively more intense rainfall across a small part of a relatively high-elevation area of the northern Black Hills on 5 August 2014. The resulting hydrologic response was noteworthy in two very small headwater drainage basins, where the...
Long-term monitoring program: Evaluating chronic exposure of harlequin ducks and sea otters to lingering Exxon Valdez Oil in Western Prince William Sound
Daniel Esler, Lizabeth Bowen, A. Keith Miles, Brenda E. Ballachey, James L. Bodkin
2015, Report
We found that average cytochrome P4501A induction (as measured by EROD activity) during March 2014 was not elevated in wintering harlequin ducks captured in areas of Prince William Sound oiled by the 1989 Exxon Valdez oil spill, relative to those captured in unoiled areas. This result is consistent with findings...

Carol A. Finn, Mason A. Kass, Bruce D. Smith
2015, Conference Paper, Symposium on the Application of Geophysics to Engineering and Environmental Problems
Earthquakes in the Raton basin near Trinidad, Colorado, (Figure 1) are located (Rubenstein et. al., 2014) near a major gravity and magnetic boundary. These earthquakes also occur in an area of hydrocarbon production that includes several high-capacity produced water injection wells. This presentation gives a very basic outline of the...
Biology and ecology of Neosho Smallmouth Bass and the genetically distinct Ouachita lineage
Shannon K. Brewer, James M. Long
Michael D. Tringali, James M. Long, Timothy W. Birdsong, Michael S. Allen, editor(s)
2015, Book chapter, Black Bass diversity: Multidisciplinary science for conservation
We reviewed the published and gray literature associated with Neosho Smallmouth Bass and the genetically-distinct Ouachita lineage. Substantial inter-stream variation appears to occur among these populations, particularly related to age. The Neosho subspecies is more abundant, grows faster, and lives longer than the genetically-distinct Ouachita lineage. Recruitment is highly variable...

2015, Seismological Research Letters (86) 1593-1602
The strongest San Francisco Bay area earthquake since the 1989 Mw 7.0 Loma Prieta shock struck near Napa on 24 August 2014. Field mapping (Dawson et al., 2014; Earthquake Engineering Research Institute [EERI], 2014; Brocher et al., 2015) and seismic and geodetic source inversions (Barnhart et al., 2015; Dreger et...

Peter Bird, David D. Jackson, Yan Y. Kagan, Corne Kreemer, Ross Stein
2015, Bulletin of the Seismological Society of America (105) 2538-2554
Global earthquake activity rate model 1 (GEAR1) estimates the rate of shallow earthquakes with magnitudes 6–9 everywhere on Earth. It was designed to be reproducible and testable. Our preferred hybrid forecast is a log–linear blend of two parent forecasts based on the Global Centroid Moment Tensor (CMT) catalog (smoothing 4602...

Andrew M. Ray, Kristin Legg, Adam J. Sepulveda, Blake R. Hossack, Debra Patla
2015, Park Science (31) 112-117
Amphibians have been selected as a “vital sign” by several National Park Service (NPS) Inventory and Monitoring (I&M) networks. An eight-year amphibian monitoring data set provided opportunities to examine spatial and temporal patterns in amphibian breeding richness and wetland desiccation across Yellowstone and Grand Teton National Parks. Amphibian breeding richness...
Development and characterization of polymorphic microsatellitemarkers for the crested caracara, Caracara cheriway
Erin E. Vaughn, James F. Dwyer, Joan L. Morrison, Melanie Culver
2015, Conservation Genetics Resources (7) 557-559
We isolated novel microsatellites from the crested caracara (Caracara cheriway) with a shotgun pyrosequencing approach. We tested 80 loci for polymorphism among 20 individuals from the threatened Florida population. Fourteen loci were polymorphic. The mean number of alleles was 2.21 (range 2–3) and the mean observed heterozygosity was 0.41 (range...
Extensive feeding on sockeye salmon Oncorhynchus nerka smolts by bull trout Salvelinus confluentus during initial outmigration into a small, unregulated and inland British Columbia river
Nathan B. Furey, Scott G. Hinch, A.G. Lotto, David A. Beauchamp
2015, Journal of Fish Biology (86) 392-401
Stomach contents were collected and analysed from 22 bull trout Salvelinus confluentus at the edge of the Chilko Lake and Chilko River in British Columbia, Canada, during spring outmigration of sockeye salmon Oncorhynchus nerka smolts. Twenty of the 22 (>90%) stomachs contained prey items, virtually all identifiable prey items were outmigrant O. nerka smolts and stomach...

Philip H. Nelson, Nicholas J. Gianoutsos, Ronald M. Drake II
2015, AAPG Bulletin (99) 1861-1892
Potentiometric surfaces for Paleozoic strata, based on water well levels and selected drill-stem tests, reveal the control on hydraulic head exerted by outcrops in eastern Kansas and Oklahoma. From outcrop in the east, the westward climb of hydraulic head is much less than that of the land surface, with heads...
Groundwater: The disregarded component in lake water and nutrient budgets, Part 1: Effects of groundwater on hydrology
Donald O. Rosenberry, Jorg Lewandowski, Karin Meinikmann, Gunnar Nutzmann
2015, Hydrological Processes (29) 2895-2921
Lake eutrophication is a large and growing problem in many parts of the world, commonly due to anthropogenic sources of nutrients. Improved quantification of nutrient inputs is required to address this problem, including better determination of exchanges between groundwater and lakes. This first of a two-part review provides a brief history of...
