2019, Pest Management Science (75) 2558-2565
Endophytes are microbes (mostly bacteria and fungi) present in plants. Endophytic microbes are often functional in that they may carry nutrients from the soil into plants, modulate plant development, increase stress tolerance of plants, suppress virulence in pathogens, increase disease resistance in plants, and suppress development of competitor plant species....

2019, Geochemistry, Geophysics, Geosystems (20) 3751-3773
Micrometer-scale maps of authigenic microstructures in submarine basaltic tuff specimens from a 1979 Surtsey volcano, Iceland, drill core acquired 15 years after eruptions terminated provide fresh perspectives for deciphering the initial alteration of oceanic basalt in a low temperature hydrothermal system. A novel investigative approach integrates synchrotron source X-ray microdiffraction...

Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases in Typha abundance in wetland ecosystems throughout North America at a cost to native floral and faunal biodiversity. As demonstrated by three regional case studies, Typha is capable of rapidly colonizing habitats and...

Christopher N. Jacques, Robert W. Klaver, Tim C. Swearingen, Edward D. Davis, Charles R. Anderson, Jonathan A. Jenks, Christopher S. DePerno, Robert D. Bluett
2019, Wildlife Society Bulletin (43) 256-264
Camera-trapping data analyzed with spatially explicit capture–recapture (SCR) models can provide a rigorous method for estimating density of small populations of elusive carnivore species. We sought to develop and evaluate the efficacy of SCR models for estimating density of a presumed low-density bobcat (Lynx rufus) population in fragmented landscapes of...
Toxicity of aluminum to Ceriodaphnia dubia in low-hardness waters as affected by natural dissolved organic matter
John M. Besser, Danielle M. Cleveland, Chris D. Ivey, Laura Blake
2019, Environmental Toxicology and Chemistry (38) 2121-2127
We conducted a series of 7‐d toxicity tests with Ceriodaphnia dubia in dilutions of low‐hardness natural waters, which contained dissolved organic carbon (DOC) concentrations up to 10 mg/L. Stream waters were mixed with well water to achieve 2 target hardness levels (20 and 35 mg/L) and 4 DOC concentrations. Tests with aluminum...

Facilitating adaptation to climate change while restoring a montane plant community
Christina Leopold, Steve C. Hess
2019, PLoS ONE (14)
Montane plant communities throughout the world have responded to changes in temperature regimes by shifting ranges upward in elevation, and made downslope movements to track shifts in climatic water balance. Organisms that cannot disperse or adapt biologically to projected climate scenarios in situ may decrease in distributional range and abundance...
Digital mapping of ecological land units using a nationally scalable modeling framework
Jonathan J. Maynard, Travis W. Nauman, Shawn W. Salley, Brandon T. Bestelmeyer, Michael C. Duniway, Curtis J. Talbot, Joel R. Brown
2019, Article
Ecological site descriptions (ESDs) and associated state-and-transition models (STMs) provide a nationally consistent classification and information system for defining ecological land units for management applications in the United States. Current spatial representations of ESDs, however, occur via soil mapping and are therefore confined to the spatial resolution used to map...

Overall Assessment Status: Fair Trends 10-Year Trend: Unchanging Long-term Trend (1973-2017): Undetermined Rationale: Great Lakes prey fish community status remains ”Fair” based on diversity and percent native species, but individual lake status varied. Both diversity and percent native metrics were classified as “Good” in Lake Superior, but “Poor” in Lake Ontario (Table 1). Lakes Huron...
Determining Moho depth beneath sedimentary basins using regional Pn multiples
C. Yu, Z. Zhan, E. Hauksson, Elizabeth S. Cochran, D. Helmberger
2019, Bulletin of the Seismological Society of America (109) 1171-1179
The study of the Moho beneath thick sedimentary basins involving natural earthquakes is challenging, as low‐velocity materials often cause strong reverberations that mask Moho signals. Here, we develop a method to determine the depth of the Moho by taking advantage of the presence of the sediments. The method utilizes the...

Roost- and perch-site selection by Golden Eagles (Aquila chrysaetos) in eastern North America
Adam E. Duerr, Melissa A. Braham, Tricia A. Miller, Jeffrey Cooper, James T. Anderson, Todd E. Katzner
2019, Wilson Journal of Ornithology (131) 310-328
Birds select critical resources to meet needs that vary in response to spatial, temporal, and individual variation. As an example, perch or roost sites may be at locations that provide protection from predators, mobbing, or inclement weather. Applied to large, soaring predators, this theory suggests...

After 53 years of quiescence, Mount Agung awoke in August 2017, with intense seismicity, measurable ground deformation, and thermal anomalies in the summit crater. Although the seismic unrest peaked in late September and early October, the volcano did not start erupting until 21 November....
Extreme site fidelity as an optimal strategy in an unpredictable and homogeneous environment
Brian D. Gerber, Mevin Hooten, Christopher P. Peck, Mindy B. Rice, James H. Gammonley, Anthony D. Apa, Amy J. Davis
2019, Functional Ecology (33) 1695-1707
1.Animal site fidelity structures space use, population demography and ultimately gene flow. Understanding the adaptive selection for site fidelity patterns provides a mechanistic understanding to both spatial and population processes. This can be achieved by linking space use with environmental variability (spatial and temporal) and demographic parameters. However, rarely is...

Christelle Wauthier, Diana C. Roman, Michael P. Poland
2019, Geology
Kīlauea Volcano is underlain by a complex, laterally-extensive magmatic plumbing system. Although in recent decades it has mainly erupted through vents along the middle East Rift Zone and summit caldera, eruptions can occur anywhere along its two laterally extensive rift zones, as demonstrated by the dramatic eruptive activity of 2018....
Widespread initiation, reactivation, and acceleration of landslides in the northern California Coast Ranges due to extreme rainfall
Alexander L. Handwerger, Eric J. Fielding, Mong-Han Huang, Georgina L. Bennett, Cunren Liang, William H. Schulz
2019, Journal of Geophysical Research: Earth Surface (24) 1782-1797
Episodically to continuously active slow-moving landslides are driven by precipitation. Climate change, which is altering both the frequency and magnitude of precipitation world21 wide, is therefore predicted to have a major impact on landslides. Here we examine the behavior of hundreds of slow-moving landslides in northern California in response to large...

Ryan D. Carle, Jonathan J. Felis, Rodrigo Vega, Jessie Beck, Josh Adams, Veronica Lopez, Peter J. Hodum, Andres Gonzalez, Valentina Colodro, Tiare Varela
2019, The Condor (121)
Understanding susceptibility of seabirds to fisheries bycatch requires quantifying overlap of seabird at-sea habitat with fisheries’ distribution and effort. Pink-footed Shearwaters (Ardenna creatopus) are vulnerable seabirds that breed only in Chile. Recently, high rates of Pink-footed Shearwater bycatch (i.e. >1,500 observed mortalities 2015–2017) were documented by observers in central Chilean...
