Ecosystem scale loss of grazing habitat impacted by abundance of dominant herbivores
Brian D. Uher-Koch, Joel A. Schmutz, Heather M. Wilson, R Michael Anthony, Thomas L Day, Thomas F Fondell, Brian T. Person, James S. Sedinger
2019, Ecosphere (10)
Grazing lawns, patches of grazing tolerant plants with high nutrient value, provide important habitat for herbivores, and changes in abundance can impact herbivore populations. Grazing lawns are maintained in quality and quantity by repeated grazing and are a result of a positive feedback since the availability of grazing lawn...

Carey Knight, Richard T. Kraus, Demetra Panos, Ann Marie Gorman, Benjamin Leonhardt, Jason Robinson, Michael J. Thomas
2019, Journal of Fish and Wildlife Management (10) 69-78
In physoclistous fishes, barotrauma caused by rapid decompression during capture may be an important source of fishing mortality that is unquantified for some fisheries. We developed a predictive logistic model for barotrauma incidence in Yellow Perch Perca flavescens and applied this model to Ohio's recreational and commercial fisheries in Lake...

Proximity to unconventional shale gas infrastructure alters breeding bird abundance and distribution
Laura S. Farwell, Petra B. Wood, Donald J. Brown, James Sheehan
2019, Ornithological Applications (121)
Unconventional shale gas development is a rapidly expanding driver of forest loss and fragmentation in the central Appalachian region. We evaluated the relationship between breeding passerine abundances and distance from shale gas development at a long-term (2008–2017) study site in northern West Virginia, USA. We examined responses of 27 species...

Taking the pulse of debris flows: Extracting debris-flow dynamics from good vibrations in southern California and central Colorado
A. Michel, Jason W. Kean, Joel B. Smith, Kate E. Allstadt, Jeffrey A. Coe
2019, Conference Paper, Association of Environmental and Engineering Geologists, Special Publication #28
The destructive nature of debris flows makes it difficult to quantify flow dynamics with direct instrumentation. For this reason, seismic sensors placed safely away from the flow path are often used to identify the timing and speed of debris flows. While seismic sensors have proven to be a valuable tool...

Before the 2018 collapse of the summit of Kīlauea volcano, a ca. 200 m in diameter lava lake inside of Halema‘uma‘u crater was embedded in a very active hydrothermal system. In 2015, we carried out an electrical conductivity survey and the data were inverted in 3D. The lack of conductivity contrast...
Microbiomes of stony and soft deep-sea corals share rare core bacteria
Christina A. Kellogg
2019, Microbiome (7)
Background: Numerous studies have shown that bacteria form stable associations with host corals and have focused on identifying conserved “core microbiomes” of bacterial associates inferred to be serving key roles in the coral holobiont. Because studies tend to focus on only stony corals (order Scleractinia) or soft corals (order Alcyonacea),...

Integrating anthropogenic factors into regional-scale species distribution models — A novel application in the imperiled sagebrush biome
Juan M. Requena-Mullor, Kaitlin C. Maguire, Douglas J. Shinneman, T. Trevor Caughlin
2019, Global Change Biology (25) 3844-3858
Species distribution models (SDM) that rely on regional-scale environmental variables will play a key role in forecasting species occurrence in the face of climate change. However, in the Anthropocene, a number of local-scale anthropogenic variables, including wildfire history, land-use change, invasive species, and ecological restoration practices can override regional-scale variables...

Feeling the sting? Addressing land-use changes can mitigate bee declines
Jennie Durant, Clint Otto
2019, Land Use Policy (87)
Pollinators are an essential component of functioning and sustainable agroecosystems. Despite their critical economic and ecological role, wild and managed bees are declining throughout the United States and across the globe. Commercial beekeepers lost nearly 40.5% of their colonies in 2015–2016 and estimated wild bee abundance declined 23% between 2008...
