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.;...

Modeling abundance using multinomial N-mixture models
J. Andrew Royle
2016, Book chapter
Multinomial N-mixture models are a generalization of the binomial N-mixture models described in Chapter 6 to allow for more complex and informative sampling protocols beyond simple counts. Many commonly used protocols such as multiple observer sampling, removal sampling, and capture-recapture produce a multivariate count frequency that has a multinomial distribution...
