Background: Bladder cancer mortality rates have been elevated in northern New England for at least five decades. Incidence rates in Maine, New Hampshire, and Vermont are about 20% higher than the United States overall. We explored reasons for this excess, focusing on arsenic in drinking water from private wells, which...

Effects of wind energy generation and white-nose syndrome on the viability of the Indiana bat
Richard A. Erickson, Wayne E. Thogmartin, James E. Diffendorfer, Robin E. Russell, Jennifer A. Szymanski
2016, PeerJ 1-19
Wind energy generation holds the potential to adversely affect wildlife populations. Species-wide effects are difficult to study and few, if any, studies examine effects of wind energy generation on any species across its entire range. One species that may be affected by wind energy generation is the endangered Indiana bat...
Impacts of short-rotation early-growing season prescribed fire on a ground nesting bird in the central hardwoods region of North America
H. Tyler Pittman, David G. Krementz
2016, PLoS ONE (11) 1-14
Landscape-scale short-rotation early-growing season prescribed fire, hereafter prescribed fire, in upland hardwood forests represents a recent shift in management strategies across eastern upland forests. Not only does this strategy depart from dormant season to growing season prescriptions, but the strategy also moves from stand-scale to landscape-scale implementation (>1,000 ha). This...

Allison H. Roy, Stephen F. Jane, Peter D. Hazelton, Todd A. Richards, John T. Finn, Timothy O. Randhir
2016, Cooperator Science Series 122-2016
With increased pressure from a growing human population, managers are challenged to understand how novel disturbances (e.g., climate change, increased water withdrawals, urbanization) may affect natural resources. The Sudbury River is a National Wild and Scenic River located in suburban Boston, Massachusetts (Northeastern US) with myriad impairments (e.g., mainstem impoundments,...

D. L. LePain, Richard G. Stanley, K. P. Helmold
2016, Preliminary Interpretive Report 2016-1-3
Geochemical data suggest the source of oil in upper Cook Inlet fields is Middle Jurassic organic-rich shales in the Tuxedni Group (Magoon and Anders, 1992; Lillis and Stanley, 2011; LePain and others, 2012, 2013). Of the six formations in the group (Detterman, 1963), the basal Red Glacier Formation is the...

2016, Journal of Volcanology and Geothermal Research (332) 71-87
Pāhoehoe lava flows are a major component of Hawaiian eruptive activity, and an important part of basaltic volcanism worldwide. In recent years, pāhoehoe lava has destroyed homes and threatened parts of Hawai‘i with inundation and disruption. In this study, we use oblique helicopter-borne thermal images to create high...

Emily W. Lankau, Gail Moede Rogall
2016, Fact Sheet 2016-3084
White-nose syndrome is a devastating wildlife disease that has killed millions of hibernating bats.

The disease is named for the...
Space use and habitat selection by resident and transient red wolves (Canis rufus)
Joseph W. Hinton, Christine Proctor, Marcella J. Kelly, Frank T. van Manen, Michael R. Vaughan, Michael J. Chamberlain
2016, PLoS ONE (11)
Recovery of large carnivores remains a challenge because complex spatial dynamics that facilitate population persistence are poorly understood. In particular, recovery of the critically endangered red wolf (Canis rufus) has been challenging because of its vulnerability to extinction via human-caused mortality and hybridization with coyotes (Canis latrans). Therefore,...

Quantification of the intrusion process at Kīlauea volcano, Hawai'i
Thomas L. Wright, Bruce Marsh
2016, Journal of Volcanology and Geothermal Research (328) 34-44
The characteristic size of two types of intrusions identified beneath Kīlauea's East Rift zone are uniquely estimated by combining time constraints from fractional crystallization and the rates of magma solidification during cooling. Some intrusions were rapidly emplaced as dikes, but stalled before reaching the surface, and cooled and crystallized to feed later fractionated eruptions. More...

David C. Lampe, Michael D. Unthank
2016, Scientific Investigations Report 2016-5125
The U.S. Geological Survey (USGS) performed tests to evaluate the hydrologic connection between the open interval of the well and the surrounding Calumet aquifer in response to fouling of extraction well pumps onsite. Two rounds of air slug testing were performed on seven monitoring wells and step drawdown and subsequent...
Climate variability and extremes, interacting with nitrogen storage, amplify eutrophication risk
Minjin Lee, Elena Shevliakova, Sergey Malyshev, P. C. D. Milly, Peter R. Jaffe
2016, Geophysical Research Letters (43) 7520-7528
Despite 30 years of basin-wide nutrient-reduction efforts, severe hypoxia continues to be observed in the Chesapeake Bay. Here we demonstrate the critical influence of climate variability, interacting with accumulated nitrogen (N) over multidecades, on Susquehanna River dissolved nitrogen (DN) loads, known precursors of the hypoxia in the Bay. We used the...
