Aquatic Ecosystem Services Survey: Round Two Results
(Montana State University, 2022-05)Wetlands, streams, and floodplains (hereafter called aquatic systems) are an important resource for social and ecological wellbeing. Since the early 1990s, Federal policy has required a no overall net loss (NNL) of wetland ... -
Aquatic Ecosystem Services Survey: Round One Results
(Montana State University, 2021-04)Wetlands, streams, and floodplains (hereafter called aquatic systems) are an important resource for social and ecological wellbeing. Since the early 1990s, Federal policy has required a no overall net loss (NNL) of wetland ... -
Microstructural and crystallographic evolution of palaeognath (Aves) eggshells
(eLife Sciences Publications, Ltd, 2023-01)The avian palaeognath phylogeny has been recently revised significantly due to the advancement of genome-wide comparative analyses and provides the opportunity to trace the evolution of the microstructure and crystallography ... -
A transitional species of Daspletosaurus Russell, 1970 from the Judith River Formation of eastern Montana
(PeerJ, 2022-11)Here we describe a new derived tyrannosaurine, Daspletosaurus wilsoni sp. nov., from Judithian strata (~76.5 Ma) intermediate in age between either of the previously described species of this genus. D. wilsoni displays a ... -
Biogeochemical Responses to Mixing of Glacial Meltwater and Hot Spring Discharge in the Mount St. Helens Crater
(Wiley, 2022-09)Environments where geothermal waters and glacier meltwater mix are common on Earth yet little is known about the biogeochemical processes that occur when hot, reduced geothermal water mixes with cold, oxidized glacial ... -
Capturing the complexity of soil evolution: Heterogeneities in rock cover and chemical weathering in Montana's Rocky Mountains
(Elsevier BV, 2022-05)We investigate the relationship between chemical weathering, persistence of soil cover, and topography in two neighboring mountain ranges in the northern Rockies of western Montana, USA. We augment existing tools for ... -
The most complete amiid fish from the Coal Creek Member of the Eocene Kishenehn Formation in northwestern Montana
(Acta Palaeontol, 2022-02)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 ... -
Outgassing through magmatic fractures enables effusive eruption of silicic magma
(Elsevier BV, 2022-10)Several mechanisms have been proposed to allow highly viscous silicic magma to outgas efficiently enough to erupt effusively. There is increasing evidence that challenges the classic foam-collapse model in which gas escapes ... -
Perceptions Among Backcountry Skiers During the COVID-19 Pandemic: Avalanche Safety and Backcountry Habits of New and Established Skiers
(Elsevier BV, 2022-12)Introduction. The coronavirus disease 2019 (COVID-19) pandemic impacted the ski industry worldwide by closing or limiting access to ski resorts. Subsequently, anecdotal reports of increased backcountry use emerged in the ... -
“In Montana, you're only a week away from a drought”: Ranchers’ perspectives on flood irrigation and beaver mimicry as drought mitigation strategies
(Elsevier BV, 2022-08)The concept of natural water storage has gained traction as an alternative to traditional dams that can potentially mitigate the impacts of changing precipitation patterns by slowing runoff and increasing aquifer recharge. ... -
Satellite detection of snow avalanches using Sentinel-1 in a transitional snow climate
(Elsevier BV, 2022-07)Snow avalanches endanger lives and infrastructure in mountainous regions worldwide. Consistent and accurate datasets of avalanche events are critical for improving hazard forecasting and understanding the spatial and ... -
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 ...
