Greater Yellowstone climate assessment: past, present, and future climate change in greater Yellowstone watersheds
(Montana State University, Institute on Ecosystems, 2021-06)The Greater Yellowstone Area (GYA) is one of the last remaining large and nearly intact temperate ecosystems on Earth (Reese 1984; NPSa undated). GYA was originally defined in the 1970s as the Greater Yellowstone Ecosystem, ... -
Resetting Southern Tibet: The serious challenge of obtaining primary records of Paleoaltimetry
(2020-08)Over the last several decades a number of studies have attempted to reconstruct the rise of the Himalaya and Tibet since India-Asia collision began in the early Cenozoic, with rather contradictory results. Here, we evaluate ... -
Using extremal events to characterize noisy time series
(2020-02)Experimental time series provide an informative window into the underlying dynamical system, and the timing of the extrema of a time series (or its derivative) contains information about its structure. However, the time ... -
Estimates of regional annual abundance and population growth rates of white sharks off central California
(2021-05)Determining population trends is critical for evaluating management actions and prioritizing species protections. In this study, we used empirical data to produce an estimate of the population trend for sub-adult and adult ... -
Horseshoe crab trace fossils from the Upper Cretaceous Two Medicine Formation of Montana, USA, and a brief review of the xiphosurid ichnological record
(2020-05)A locality in the Upper Cretaceous Two Medicine Formation of Montana preserves abundant and variable horseshoe crab tracks and trails of the ichnotaxon Kouphichnium isp. These specimens span six morphologies differing in ... -
Insect trace fossils elucidate depositional environments and sedimentation at a dinosaur nesting site from the Cretaceous (Campanian) Two Medicine Formation of Montana
(2019-11)We describe the diversity and abundance of insect (specifically hymenopterans and coleopterans) pupation structures in the Upper Cretaceous (Campanian) Two Medicine Formation at the Egg Mountain locality, western Montana, ... -
Retreat but no surrender: net-spinning caddisfly (Hydropsychidae) silk has enduring effects on stream channel hydraulics
(2020-02)Animals and plants engineer their physical environment by building structures that create or modify habitat. Biotic effects on physical habitats can influence community composition, trophic dynamics, and ecosystem processes; ... -
Metabolic Implications of Using BioOrthogonal Non-Canonical Amino Acid Tagging (BONCAT) for Tracking Protein Synthesis
(2020-02)BioOrthogonal Non-Canonical Amino acid Tagging (BONCAT) is a powerful tool for tracking protein synthesis on the level of single cells within communities and whole organisms. A basic premise of BONCAT is that the non-canonical ... -
Multi-parameter exploration of dynamics of regulatory networks
(2020-04)Over the last twenty years advances in systems biology have changed our views on microbial communities and promise to revolutionize treatment of human diseases. In almost all scientific breakthroughs since time of Newton, ... -
Tired Teens: Sleep Disturbances and Heightened Vulnerability for Mental Health Difficulties
(2020-05)Inadequate sleep is one of the most common yet modifiable public health problems facing youth today, and accumulating evidence suggests that sleep problems are associated with increased risk for mental health difficulties ... -
The design of tasks that address applications to teaching secondary mathematics for use in undergraduate mathematics courses
(Elsevier, 2020-12)his paper describes theoretical design principles emerging from the development of tasks for standard undergraduate mathematics courses that address applications to teaching secondary mathematics. While researchers recognize ... -
A New Sample of (Wandering) Massive Black Holes in Dwarf Galaxies from High-resolution Radio Observations
(2020-01)We present a sample of nearby dwarf galaxies with radio-selected accreting massive black holes (BHs), the majority of which are non-nuclear. We observed 111 galaxies using sensitive, high-resolution observations from the ... -
Ideal points of character varieties, algebraic non-integral representations, and undetected closed essential surfaces in 3-manifolds
(2020-02)Closed essential surfaces in a 3-manifold can be detected by ideal points of the character variety or by algebraic non-integral representations. We give examples of closed essential surfaces not detected in either of these ... -
New occurrence of Neurankylus sp. (Testudines: Paracryptodiria: Baenidae) in the Upper Cretaceous Frontier Formation of south western Montana (USA)
(2020-04)An incomplete specimen assigned to the genus Neurankylus sp. was collected from Coniacian deposits of the Frontier Formation of Montana (USA). The material consists of anterior plastron, a costal plate and neural plate ... -
The indirect paths to cascading effects of extinctions in mutualistic networks
(2020-05)Biodiversity loss is a hallmark of our times, but predicting its consequences is challenging. Ecological interactions form complex networks with multiple direct and indirect paths through which the impacts of an extinction ... -
Lie Algebroids As L[infinity] Spaces
(2018-02)In this paper, we relate Lie algebroids to Costello’s version of derived geometry. For instance, we show that each Lie algebroid – and the natural generalization to dg Lie algebroids – provides an (essentially unique) L ... -
Copper modulates sex-specific fructose hepatoxicity in nonalcoholic fatty liver disease (NALFD) Wistar rat models
(2020-04)This study aimed to characterize the impact of dietary copper on the biochemical and hepatic metabolite changes associated with fructose toxicity in a Wistar rat model of fructose-induced liver disease. Twenty-four male ... -
Assessing the Performance of Index Calibration Survey Methods to Monitor Populations of Wide‐ranging Low‐density Carnivores
(2020-03)Apex carnivores are wide‐ranging, low‐density, hard to detect, and declining throughout most of their range, making population monitoring both critical and challenging. Rapid and inexpensive index calibration survey (ICS) ... -
Carnivores, competition and genetic connectivity in the Anthropocene
(2019-11)Current extinction rates are comparable to five prior mass extinctions in the earth’s history, and are strongly affected by human activities that have modified more than half of the earth’s terrestrial surface. Increasing ... -
Daedalus: a low-flying spacecraft for in situ exploration of the lower thermosphere–ionosphere
(2020-04)The Daedalus mission has been proposed to the European Space Agency (ESA) in response to the call for ideas for the Earth Observation program's 10th Earth Explorer. It was selected in 2018 as one of three candidates for a ...
