Evolutionary Divergence of Marinobacter Strains in Cryopeg Brines as Revealed by Pangenomics
(Frontiers Media SA, 2022-06)Marinobacter spp. are cosmopolitan in saline environments, displaying a diverse set of metabolisms that allow them to competitively occupy these environments, some of which can be extreme in both salinity and temperature. ... -
The dynamic floor of Yellowstone Lake, Wyoming, USA: The last 14 k.y. of hydrothermal explosions, venting, doming, and faulting
(Geological Society of America, 2022-06)Hydrothermal explosions are significant potential hazards in Yellowstone National Park, Wyoming, USA. The northern Yellowstone Lake area hosts the three largest hydrothermal explosion craters known on Earth empowered by ... -
Colours and maps for communicating natural hazards to users with and without colour vision deficiency
(Elsevier BV, 2022-06)Natural hazards are often communicated visually using colours and maps. However, users' ability to read and understand these products may be hampered by e.g., colour vision deficiency, potentially rendering the products ... -
The Most Complete Bowfin (Amiidae: Amia sp.) from the Coal Creek Member of the Kishenehn Formation (Eocene), Northwestern Montana
(Polska Akademia Nauk Instytut Paleobiologii, 2022-01)The larger-bodied fish fauna of the Kishenehn Formation’s Coal Creek Member (Eocene, 43.5 Ma), northwestern Montana, is understudied because of a sampling bias towards small specimens. Small specimens (<10 cm length) of ... -
The diverse terminology of reptile eggshell microstructure and its effect on phylogenetic comparative analyses
(Wiley, 2022-06)Reptile eggshell ensures water and gas exchange during incubation and plays a key role in reproductive success. The diversity of reptilian incubation and life history strategies has led to many clade-specific structural ... -
New Paleomagnetic Constraints on the Early Cretaceous Paleolatitude of the Lhasa Terrane (Tibet)
(Frontiers Media SA, 2022-05)New zircon U-Pb dating results from the Zonggei Formation volcanics indicate that the volcanic rocks formed at ∼114–110 Ma. Paleomagnetic data, petrography, and rock magnetism confirm the primary nature of isolated ... -
Tracking decision-making of backcountry users using GPS tracks and participant surveys
(Elsevier BV, 2022-07)Snow avalanches are a significant natural hazard representing the primary risk of death to backcountry travelers in many alpine countries. Careful use of backcountry terrain through effective decision making can mitigate ... -
The intersection of geoethics and diversity in the geosciences
(Geological Society of London, 2020-12)The geosciences (inclusive of geology, oceanography, atmospheric science and allied disciplines) have an ethical imperative to increase diversity in the profession. The diverse ways of exploring the Earth system, and the ... -
Should I judge safety or danger? Perceived risk depends on the question frame.
(American Psychological Association, 2021-04)Linguistic polarity is a natural characteristic of judgments: Is that situation safe/dangerous? How difficult/easy was the task? Is that politician honest/dishonest? Across six studies (N = 1599), we tested how the qualitative ... -
Rock weathering and nutrient cycling along an erodosequence
(American Journal of Science, 2021-10)How flowing water and organisms can shape Earth's surface, the Critical Zone, depends on how fast this layer is turned over by erosion. To quantify the dependence of rock weathering and the cycling of elements through ... -

Measuring conservation program best management practice implementation and maintenance at the watershed scale
(Soil and Water Conservation Society, 2010-11)There is growing interest in evaluating the impacts at the watershed scale of agricultural best management practices (BMPs) designed to improve water quality. Many approaches to impact assessment require detailed information ... -
Defining Ecological Drought for the Twenty-First Century
(American Meteorological Society, 2017-12)Droughts of the twenty-first century are characterized by hotter temperatures, longer duration, and greater spatial extent, and are increasingly exacerbated by human demands for water. This situation increases the vulnerability ... -
Cultural theory of risk as a heuristic for understanding perceptions of oil and gas development in Eastern Montana, USA
(Elsevier BV, 2017-11)This paper applies Douglas’ cultural theory of risk to understand perceptions of risk associated with oil and gas development in eastern Montana. Based on the analysis of interviews with 36 rural residents, findings show ... -
Ecological Drought: Accounting for the Non-Human Impacts of Water Shortage in the Upper Missouri Headwaters Basin, Montana, USA
(MDPI AG, 2018-02)Water laws and drought plans are used to prioritize and allocate scarce water resources. Both have historically been human-centric, failing to account for non-human water needs. In this paper, we examine the development ... -
Integrating Ecological Impacts: Perspectives on Drought in the Upper Missouri Headwaters, Montana, United States
(American Meteorological Society, 2021-04)Drought is a complex challenge experienced in specific locations through diverse impacts, including ecological impacts. Different professionals involved in drought preparedness and response approach the problem from different ... -
Murky waters: divergent ways scientists, practitioners, and landowners evaluate beaver mimicry
(Resilience Alliance, Inc., 2022-01)Beaver mimicry is a fast-growing conservation technique to restore streams and manage water that is gaining popularity within the natural resource management community because of a wide variety of claimed socio-environmental ... -
Subglacial erosion has the potential to sustain microbial processes in Subglacial Lake Whillans, Antarctica
(Springer Science and Business Media LLC, 2021-06)Subglacial Lake Whillans lies below around 800 m of Antarctic ice and is isolated from fresh sources of photosynthetic organic matter to sustain life. The diverse microbial ecosystems within the lake and underlying sediments ... -
New snow metrics for a warming world
(Wiley, 2021-06)Snow is Earth's most climatically sensitive land cover type. Traditional snow metrics may not be able to adequately capture the changing nature of snow cover. For example, April 1 snow water equivalent (SWE) has been an ... -
A typology of drought decision making: Synthesizing across cases to understand drought preparedness and response actions
(Elsevier BV, 2021-09)Drought is an inescapable reality in many regions, including much of the western United States. With climate change, droughts are predicted to intensify and occur more frequently, making the imperative for drought management ...
