Mosses in Ohio wetlands respond to indices of disturbance and vascular plant integrity
Martin A. Stapanian, William Schumacher, Brian Gara, Nick Viau
2016, Ecological Indicators (63) 110-120
We examined the relationships between an index of wetland habitat quality and disturbance (ORAM score) and an index of vascular plant integrity (VIBI-FQ score) with moss species richness and a moss quality assessment index (MQAI) in 45 wetlands in three vegetation types in Ohio, USA. Species richness of mosses and...

Soil carbon (C) is a critical component of Earth system models (ESMs), and its diverse representations are a major source of the large spread across models in the terrestrial C sink from the third to fifth assessment reports of the Intergovernmental Panel on Climate Change (IPCC). Improving soil C projections...
Pre-Mississippian tectonic affinity across the Canada Basin–Arctic margins of Alaska and Canada
David W. Houseknecht, Christopher D. Connors
2016, Geology (44) 507-510
New and reprocessed seismic reflection data on the Alaskan and Canadian Arctic margins of the Canada Basin, together with geologic constraints from exploration wells and outcrops, reveal structural and stratigraphic relationships in pre-Mississippian rocks that constrain models of Canada Basin opening. Lithostratigraphic age and acoustic character indicate that the Devonian...
Slab-rollback ignimbrite flareups in the southern Great Basin and other Cenozoic American arcs: A distinct style of arc volcanism
Myron G. Best, Eric H. Christiansen, Shanaka de Silva, Peter W. Lipman
2016, Geosphere (12) 1097-1135
In continental-margin subduction zones, basalt magmas spawned in the mantle interact with the crust to produce a broad spectrum of volcanic arc associations. A distinct style of very voluminous arc volcanism develops far inland on thick crust over periods of 10–20 m.y. and involves relatively infrequent caldera-forming explosive eruptions of...
The Aleutian-Bering Climate Vulnerability Assessment
Aaron Poe, Thomas I. van Pelt, Jeremy S. Littell, editor(s)
2016, Report
Recent efforts to develop downscaled climate projections for the Bering Sea and Aleutians created an opportunity to better assess regional vulnerability to climate change. The Aleutian BeringClimate Vulnerability Assessment (ABCVA) was launched in 2014 to bring together regional science expertise and stakeholder interests in a rapid evaluation of the implications...
Invasive pythons, not anthropogenic stressors, explain the distribution of a keystone species
Adia R. Sovie, Robert A. McCleery, Robert J. Fletcher, Kristen M. Hart
2016, Biological Invasions (18) 3309-3318
Untangling the causes of native species loss in human-modified systems is difficult and often controversial. Evaluating the impact of non-native species in these systems is particularly challenging, as additional human perturbations often precede or accompany introductions. One example is the ongoing debate over whether mammal declines within Everglades National Park...
Along-strike variations in fault frictional properties along the San Andreas Fault near Cholame, California from joint earthquake and low-frequency earthquake relocations
Rebecca M. Harrington, Elizabeth S. Cochran, Emily M. Griffiths, Xiangfang Zeng, Clifford H. Thurber
2016, Bulletin of the Seismological Society of America (106) 319-326
Recent observations of low‐frequency earthquakes (LFEs) and tectonic tremor along the Parkfield–Cholame segment of the San Andreas fault suggest slow‐slip earthquakes occur in a transition zone between the shallow fault, which accommodates slip by a combination of aseismic creep and earthquakes (<15 km depth), and the deep fault, which accommodates slip...

Distributions of small nongame fishes in the lower Yellowstone River
Michael B. Duncan, Robert G. Bramblett, Alexander V. Zale
2016, American Midland Naturalist (175) 1-23
The Yellowstone River is the longest unimpounded river in the conterminous United States. It has a relatively natural flow regime, which helps maintain diverse habitats and fish assemblages uncommon in large rivers elsewhere. The lower Yellowstone River was thought to support a diverse nongame fish assemblage including several species of...
Tamarisk beetle (Diorhabda spp.) in the Colorado River basin: Synthesis of an expert panel forum

2016, Report, Ruth Powell Hutchins Water Center scientific and technical report series
Executive Summary In 2001, the U.S. Department of Agriculture approved the release of a biological control agent, the tamarisk beetle (Diorhabda spp.), to naturally control tamarisk populations and provide a less costly, and potentially more effective, means of removal compared with mechanical and chemical methods. The invasive plant tamarisk (Tamarix spp.;...

Analysis and interpretation of stress indicators in deviated wells of the Coso Geothermal Field
Martin Schoenball, Jonathan M. G. Glen, Nicholas C. Davatzes
2016, Conference Paper, Proceedings of the 41st workshop on geothermal reservoir engineering
Characterizing the tectonic stress field is an integral part of the development of hydrothermal systems and especially for enhanced geothermal systems (EGS). With a well characterized stress field the propensity of fault slip on faults with known location and orientation can be identified. Faults that are critically oriented for faulting...
Testing an attachment method for solar-powered tracking devices on a long-distance migrating shorebird
Ying-Chi Chan, Martin Brugge, T. Lee Tibbitts, Anne Dekinga, Ron Porter, Raymond H. G. Klaassen, Theunis Piersma
2016, Journal of Ornithology (157) 277-287
Small solar-powered satellite transmitters and GPS data loggers enable continuous, multi-year, and global tracking of birds. What is lacking, however, are reliable methods to attach these tracking devices to small migratory birds so that (1) flight performance is not impacted and (2) tags are retained during periods of substantial mass...
Water data to answer urgent water policy questions: Monitoring design, available data, and filling data gaps for determining whether shale gas development activities contaminate surface water or groundwater in the Susquehanna River Basin
Elin A. Betanzo, Erik R. Hagen, John T. Wilson, Kenneth H. Reckhow, Laura Hayes, Denise M. Argue, Allegra A. Cangelosi
2016, Report
Throughout its history, the United States has made major investments in assessing natural resources, such as soils, timber, oil and gas, and water. These investments allow policy makers, the private sector and the American public to make informed decisions about cultivating, harvesting or conserving these resources to maximize their value...
Functional integrity of freshwater forested wetlands, hydrologic alteration, and climate change
Beth A. Middleton, Nicholas J. Souter
2016, Ecosystem Health and Sustainability (2) 1-18
Climate change will challenge managers to balance the freshwater needs of humans and wetlands. The Intergovernmental Panel on Climate Change predicts that most regions of the world will be exposed to higher temperatures, CO2, and more erratic precipitation, with some regions likely to have alternating episodes of intense flooding and...

Does the stress-gradient hypothesis hold water? Disentangling spatial and temporal variation in plant effects on soil moisture in dryland systems
Bradley J. Butterfield, John B. Bradford, Cristina Armas, Ivan Prieto, Francisco I. Pugnaire
2016, Functional Ecology (30) 10-19
The nature of the relationship between water limitation and facilitation has been one of the most contentious debates surrounding the stress-gradient hypothesis (SGH), which states that plant-plant interactions shift from competition to facilitation with increasing environmental stress. We take a closer look at the potential role of soil...
