Combining process-based and data-driven approaches to forecast beach and dune change
Michael Itzkin, Laura J. Moore, Peter Ruggiero, Paige A. Hovenga, Sally D. Hacker
2022, Environmental Modelling & Software (153)
Producing accurate hindcasts and forecasts with coupled models is challenging due to complex parameterizations that are difficult to ground in observational data. We present a calibration workflow that utilizes a series of machine learning algorithms paired with Windsurf, a coupled beach-dune model (Aeolis, the Coastal Dune Model, and XBeach), to produce hindcasts and forecasts of...

Many discoveries of active surface processes on Mars have been made due to the availability of repeat high-resolution images from the High Resolution Imaging Science Experiment (HiRISE) onboard the Mars Reconnaissance Orbiter. HiRISE stereo images are used to make digital terrain models (DTMs) and orthorectified images (orthoimages)....
Lithospheric conductors reveal source regions of convergent margin mineral systems
Alison Kirkby, Karol Czarnota, David L. Huston, David C. Champion, Michael P. Doublier, Paul A. Bedrosian, Jinming Duan, Graham Heinson
2022, Scientific Reports (12)
The clean energy transition will require a vast increase in metal supply, yet new mineral deposit discoveries are declining, due in part to challenges associated with exploring under sedimentary and volcanic cover. Recently, several case studies have demonstrated links between lithospheric electrical conductors imaged using magnetotelluric (MT)...
Global cycling and climate effects of aeolian dust controlled by biological soil crusts
Rodriguez-Caballero, T Stanelle, S Egerer, Yang Cheng, H. E. Suess, Y Canton, Jayne Belnap, M O Andreae, I Tegen, C Reick, Ulrich Poschl, B. Weber
2022, Nature Geoscience (15) 458-463
Biological soil crusts (biocrusts) cover ~12% of the global land surface. They are formed by an intimate association between soil particles, photoautotrophic and heterotrophic organisms, and they effectively stabilize the soil surface of drylands. Quantitative information on the impact of biocrusts on the global cycling and climate effects of aeolian...

Cory T. Overton, Michael L. Casazza, Joseph Bretz, Fiona McDuie, Elliott Matchett, Desmond Alexander Mackell, Austen Lorenz, Andrea Mott, Mark P. Herzog, Joshua T. Ackerman
2022, Movement Ecology (10)
BackgroundIdentifying animal behaviors, life history states, and movement patterns is a prerequisite for many animal behavior analyses and effective management of wildlife and habitats. Most approaches classify short-term movement patterns with high frequency location or accelerometry data. However, patterns reflecting life history across longer time scales can have...
Earthquakes indicated stress field change during the 2006 unrest of Augustine Volcano, Alaska
Yan Zhan, Diana Roman, Helene Le Mevel, John Power
2022, Geophysical Research Letters (49)
To examine controls on the local stress field at Augustine Volcano, Alaska, before its 2006 eruption, we calculated fault plane solutions for volcano-tectonic earthquakes from 2002 to 2006. The P-axis orientation was first aligned to the regional maximum compression (NW) and then rotated by about 90° (perpendicular to the dike...
Using a multi-model ensemble approach to determine biodiversity hotspots with limited occurrence data in understudied areas: An example using freshwater mussels in México
Alexander H. Kiser, Kevin S. Cummings, Jeremy S. Tiemann, Chase H. Smith, Nathan A. Johnson, Roel R. Lopez, Charles R. Randklev
2022, Ecology and Evolution (15)
Species distribution models (SDMs) are an increasingly important tool for conservation particularly for difficult-to-study locations and with understudied fauna. Our aims were to (1) use SDMs and ensemble SDMs to predict the distribution of freshwater mussels in the Pánuco River Basin in Central México; (2) determine...
Accessibility of environmental data for sharing: The role of UX in large cyberinfrastructure projects
Rachel Volentine, Alison Specht, Suzie Allard, Mike Frame, Rachael Hu, Lisa Zolly
2022, Ecological Informatics (63)
Incorporating user experience (UX) testing when creating research cyberinfrastructure is often overlooked, but if left too late, the cost of retrofitting is considerable, and the very clients the cyberinfrastructure was built to serve may be lost. Successfully integrating UX testing into the product...
Quantifying the conservation status and abundance trends of wildlife communities with detection-nondetection data
Matthew T Farr, Timothy O O’Brien, Charles B. Yackulic, Elise F. Zipkin
2022, Conservation Biology (36)
Effective conservation requires understanding species' abundance patterns and demographic rates across space and time. Ideally, such knowledge should be available for whole communities, as variation in species' dynamics can elucidate factors leading to biodiversity losses. However, collecting data to simultaneously estimate abundance and demographic rates is often prohibitively time-intensive and...

D. Kirk Nordstrom
2022, Mineralogical Magazine (86) 652-660
Thermodynamic data are constrained by the interrelated thermodynamic equations in addition to the observational measurements and their uncertainties. The consequence is a network of thermodynamic properties that can be evaluated for their internal consistency. In this study, three fluoride minerals that can cause high fluoride concentrations in...

Estimating occupancy from autonomous recording unit data in the presence of misclassifications and detection heterogeneity
Matt Clement, J. Andrew Royle, Ronald Mixan
2022, Methods in Ecology and Evolution (13) 1719-1729
1. Autonomous Recording Units (ARUs) are now widely used to survey communities of species. These surveys generate spatially and temporally replicated counts of unmarked animals, but such data typically include false negatives and misclassified detections, both of which may vary across sites in proportion to abundance. These data challenges can...
