Resilience of riparian vegetation productivity to early 21st century drought in northern California, USA
Paul Selmants, Caroline Rose Conrad, Tamara S. Wilson, Miguel L. Villarreal
2023, Ecosphere (14)
Drought and intensive land use can interact as stressors on riparian vegetation, especially along rivers flowing through seasonally dry landscapes. Knowledge of past riparian vegetation response to drought and land use change can provide land managers with a better understanding of changes induced by...
Biophysical factors control invasive annual grass hot spots in the Mojave Desert
Tanner Corless Smith, Tara B.B. Bishop, Michael C. Duniway, Miguel L. Villarreal, Anna C Knight, Seth M. Munson, Eric K. Waller, Ryan Jensen, Richard A. Gill
2023, Biological Invasions (25) 3839-3859
Invasive annual grasses can promote ecosystem state changes and habitat loss in the American Southwest. Non-native annual grasses such as Bromus spp. and Schismus spp. have invaded the Mojave Desert and degraded habitat through increased fire occurrence, severity, and shifting plant community composition. Thus, it is important to identify and...
Toxic algae in inland waters of the conterminous United States—A review and synthesis
Reynaldo Patiño, Victoria Christensen, Jennifer L. Graham, Jane Rogosch, Barry H. Rosen
2023, Water (15)
Cyanobacteria are the most common toxigenic algae in inland waters. Their toxins can affect the health of aquatic and terrestrial organisms, including humans. Other algal groups, such as haptophytes (e.g., Prymnesium parvum) and euglenoids (e.g., Euglena sanguinea), can also form harmful algal blooms (HABs) whose toxins cause injury to...
Potassium-39-derived 36Ar production during fission-neutron irradiation and its effect on 40Ar/39Ar ages
Jack N. Carter, Paul R. Renne, Leah E. Morgan
2023, Geochimica et Cosmochimica Acta (357) 26-34
Various interference reactions producing unwanted Ar isotopes from K, Ca, Cl and Ar require correction to satisfy the 40Ar/39Ar age equation. Using GEANT4, we design and build a model Cadmium Lined In Core Irradiation Tube (CLICIT) irradiation facility, as used in the...

Flor Vermassen, Matt O'Regan, Agatha de Boer, Freederik Schenk, Mohammad Razmjooei, Gabriel West, Thomas M. Cronin, Martin Jakobsson, Helen Coxall
2023, Nature Geoscience (16) 723-729
The extent and seasonality of Arctic sea ice during the Last Interglacial (129,000 to 115,000 years before present) is poorly known. Sediment-based reconstructions have suggested extensive ice cover in summer, while climate model outputs indicate year-round conditions in the Arctic Ocean ranging from ice free to...

Illegal shooting is now a leading cause of death of birds along power lines in the western USA
Eve C. Thomason, Natalie J.S. Turley, James R. Belthoff, Tara Conkling, Todd E. Katzner
2023, iScience (26)
Human actions, both legal and illegal, affect wildlife in many ways. Inaccurate diagnosis of cause of death undermines law enforcement, management, threat assessment, and mitigation. We found 410 dead birds collected along 196 km of power lines in four western USA states during 2019 – 2022. We necropsied these carcasses...

Bayesian spatio-temporal survival analysis for all types of censoring with application to a wildlife disease study
Kehui Yao, Jun Zhu, Daniel J. O'Brien, Daniel P. Walsh
2023, Environmetrics (34)
In this article, we consider modeling arbitrarily censored survival data with spatio-temporal covariates. We demonstrate that under the piecewise constant hazard function, the likelihood for uncensored or right-censored subjects is proportional to the likelihood of multiple conditionally independent Poisson random variables. To address left- or interval-censored subjects, we propose to...

The During Nearshore Event Experiment (DUNEX) was a large-scale coastal field effort focused on improving understanding of during-storm nearshore processes to ultimately develop predictive technologies, engineering solutions, and actions to enhance coastal resilience. The experiments were conducted on the North Carolina coast by a multidisciplinary group of over 30 research...
Towards improved code-based performance objectives for liquefaction hazard analysis
Andrew James Makdisi, Steven L. Kramer
2023, Conference Paper, Proceedings, 4th international conference on applications of statistics and probability in civil engineering (ICASP14)
Ground failure due to liquefaction in loose sand deposits poses substantial risks to the built environment, and has caused significant damage in past earthquakes to a wide range of infrastructure. Advances in liquefaction hazard analysis in practice have largely stagnated in recent years; the state of practice remains rooted in...

2023, Scientific Reports (13)
Tropical forest fragmentation from agricultural expansion alters the microclimatic conditions of the remaining forests, with effects on vegetation structure and function. However, little is known about how the functional trait variability within and among tree species in fragmented landscapes influence and facilitate species’ persistence in these...
A review of geology and mining in the Marble Mountains, southeastern California
David C. Buesch, Bruce W. Bridenbecker
2023, Conference Paper, 2023 Desert Symposium Field Guide and Proceedings: Mines of the Mojave
Mining in the Marble Mountains of southeastern California was active in the earliest 1900s and gradually declined to very few active mines by 1959. Most mining consisted of hard-rock prospects and mines, with a few soft-rock prospects and one mine. The Marble Mountains are a 10 km by 30 km,...
