Michael Poland, Daniele Carbone, Matthew R. Patrick
2021, Earth and Planetary Science Letters (567)
Prior to the 2018 lower East Rift Zone (ERZ) eruption and summit collapse of Kīlauea Volcano, Hawai‘i, continuous gravimeters operated on the vent rims of ongoing eruptions at both the summit and Pu‘u ‘Ō‘ō. These instruments captured the onset of the 2018 lower ERZ eruption and the effects of lava...

2021, Journal of Volcanology and Geothermal Research (417)
Eruptive column models are powerful tools for investigating the transport of volcanic gas and ash, reconstructing past explosive eruptions, and simulating future hazards. However, the evaluation of these models is challenging as it requires independent estimates of the main model inputs...
Species mixture effects and climate influence growth, recruitment and mortality in Interior West USA Populus tremuloides-conifer communities
Christopher E. Looney, Wilfred J Previant, John B. Bradford, Linda M Nagel
2021, Journal of Ecology (109) 2934-2949
Tree-species mixture effects (e.g. complementarity and facilitation) have been found to increase individual-tree productivity, lessen mortality and improve recruitment in forests worldwide. By promoting more efficient and complete resource use, mixture effects may also lessen individual-tree-level water stress, thus improving drought resistance. We investigated the influence of mixture effects...
Time marches on, but do the causal pathways driving instream habitat and biology remain consistent?
Richard H Walker, Matthew J. Ashton, Matthew J. Cashman, Rosemary M. Fanelli, Kevin P. Krause, Gregory E. Noe, Kelly O. Maloney
2021, Science of the Total Environment (789)
Stream ecosystems are complex networks of interacting terrestrial and aquatic drivers. To untangle these ecological networks, efforts evaluating the direct and indirect effects of landscape, climate, and instream predictors on biological condition through time are needed. We used structural equation modeling and leveraged a...

T. Hafen, A.T. Taylor, D.A. Hendrickson, D.R. Stewart, James M. Long
2021, North American Journal of Fisheries Management (41) S54-S63
The Yaqui Catfish Ictalurus pricei is an understudied species, with limited information available on its ecology, distribution, and local habitat use. Native to the southwestern United States and northwestern Mexico, Yaqui Catfish populations are declining, which has prompted listing of the species as threatened in the United States and as a species...
Comment on ‘New insights on Franciscan Complex geology, architecture, depositional age, and provenance for the western Mt. Tamalpais area, Marin County, California’ by Bero et al. (2020)
Russell Graymer, Trevor A. Dumitru, Robert J. McLaughlin, Carl M. Wentworth
2021, International Geology Review (64) 1191-1197
Serious errors and inconsistencies in the article undermine many of its interpretations to the point that principal conclusions are not valid. Much dependence is placed on the maximum depositional age (Dmax) of sandstone units based on zircon analysis of 10 samples, but calculation of those Dmax values is flawed, and...

J. Soubestre, B. Chouet, Phillip B. Dawson
2021, Journal of Geophysical Research: Solid Earth (126)
Volcanic tremor occurring at the beginning of the 2018 Kīlauea eruption is characterized using both seismic and tilt data recorded at the Kīlauea summit. An automatic seismic network-based approach detects several types of tremor including (a) 0.5–1 Hz long-period tremor preceding the eruption, located at the south-southwest edge...

Key characteristics of Pb-Zn deposits were identified in available datasets and...
Modeling effects of disturbance across life history strategies of stream fishes
Robert J. Fournier, Nick R. Bond, Daniel D. Magoulick
2021, Oecologia (196) 413-425
A central goal of population ecology is to establish linkages between life history strategy, disturbance, and population dynamics. Globally, disturbance events such as drought and invasive species have dramatically impacted stream fish populations and contributed to sharp declines in freshwater biodiversity. Here, we used RAMAS-Metapop to construct stage-based demographic metapopulation...
An empirically based simulation model to inform flow management for endangered species conservation
Timothy E. Walsworth, Phaedra E. Budy
2021, Canadian Journal of Fisheries and Aquatic Sciences (78) 1770-1781
Increasing water demand, water development, and ongoing climate change have driven extensive changes to the hydrology, geomorphology and biology of arid-land rivers globally, driving an increasing need to understand how annual hydrologic conditions affect the distribution and abundance of imperiled desert fish populations. We analyzed the relationship between annual hydrologic...
Development of soil radiocarbon profiles in a reactive transport framework
Jennifer Druhan, Corey Lawrence
2021, Geochimica et Cosmochimica Acta (306) 63-83
Today, there is a greater appreciation for the importance of the physical protection of carbon (C) through interactions with mineral surfaces, isolation from microbes, and the important role of transport in shaping soil properties and controlling moisture limitations on decomposition. As our paradigm for soil organic carbon (SOC) preservation changes, so too should our representation...

Rosalyn L Putland, Marybeth K. Brey, Allen F. Mensinger
2021, Journal of Environmental Management (296)
Vessel sound is now globally recognized as a significant and pervasive pollutant to aquatic life. However, compared to marine environments, there is a paucity of data on sound emitted by vessel activity in freshwater habitats. The Upper Mississippi River (UMR) is home...

Jordan Dornbierer, Steve Wika, Charles Robison, Gregory Rouze, Terry L. Sohl
2021, Land (10)
Land system change has been identified as one of four major Earth system processes where change has passed a destabilizing threshold. A historical record of landscape change is required to understand the impacts change has had on human and natural systems, while scenarios of future landscape change are required to...

Eric V. Regehr, Markus Dyck, Samuel A. Iverson, David S. Lee, Nicholas J Lunn, Joseph M Northrup, Marie-Claude Richer, Guillaume Szor, Michael C. Runge
2021, Biological Conservation (258)
Arctic marine mammals are harvested by Indigenous people for subsistence and are socially and culturally important. For ice-dependent species like the polar bear Ursus maritimus, management and conservation require understanding interactions between harvest and sea-ice loss due to climate change. We developed a demographic...

Maurizio Battaglia, Carolina Paglia, Stefano Meuti
2021, Remote Sensing (13)
In this work, we study the subsidence of Dallol, an explosive crater and hydrothermal area along the spreading Erta Ale ridge of Afar (Ethiopia). No volcanic products exist at the surface. However, a diking episode in 2004, accompanied by dike-induced faulting, indicates that Dallol is an active...

Izaya Numata, Kul Bikram Khand, Jeppe Kjaersgaard, Mark A. Cochrane, Sonaira S. Silva
2021, Agricultural and Forest Meteorology (306)
Ongoing climate change and human conversion of forests to other land uses alter regional evapotranspiration dynamics and, consequently, impact associated hydrological systems in Amazonia. We studied the effects of drought and fragmentation on forest evapotranspiration using the surface energy balance-based model METRIC (Mapping Evapotranspiration at high Resolution with Internalized...
