2024, Scientific Data (11)
Lake trophic state is a key ecosystem property that integrates a lake’s physical, chemical, and biological processes. Despite the importance of trophic state as a gauge of lake water quality, standardized and machine-readable observations are uncommon. Remote sensing presents an opportunity to detect and analyze lake...
Nanoscale silicate melt textures determine volcanic ash surface chemistry
Adrian Hornby, Paul M Ayris, David Damby, Spyros Diplas, Julia Eychenne, Jackie E. Kendrick, Corrado Cimarelli, Ulli Kueppers, Bettina Scheu, James E. P. Utley, Donald B. Dingwell
2024, Nature Communications (15)
Explosive volcanic eruptions produce vast quantities of silicate ash, whose surfaces are subsequently altered during atmospheric transit. These altered surfaces mediate environmental interactions, including atmospheric ice nucleation, and toxic effects in biota. A lack of knowledge of the initial, pre-altered ash surface has required previous studies to assume that the...

Remotely sensed evapotranspiration (ET) data offer strong potential to support data-driven approaches for sustainable water management. However, practitioners require robust and rigorous accuracy assessments of such data. The OpenET system, which includes an ensemble of six remote sensing models, was developed to increase access to field-scale...
Shoreline slope influences movements of larval lampreys over dewatered substrate
Theresa L. Liedtke, Julianne E. Harris, Ann E. Gray
2024, Aquaculture, Fish and Fisheries (4) 1-14
Larval lampreys are filter feeders that live for several years burrowed in fine sediments in freshwater streams. Stream side channels and edges, where larval lampreys gather, are vulnerable to natural and human-caused dewatering. Water level reductions can strand and kill thousands of larval lampreys,...
Prey selection by black-footed ferrets (Mustela nigripes): Implications for intersexual resource partitioning and conservation
Dean E. Biggins, David A. Eads, Shantini Ramakrishnan, Amanda R. Goldberg, Samantha L. Eads, Joanna Hardin, Darla Konkel
2024, Journal of Mammalogy (105) 221-229
Intraspecific resource partitioning may play a critical role in how predators optimize prey selection. The Black-footed Ferret (Mustela nigripes; henceforth, ferret) is a highly specialized predator of prairie dogs (Cynomys spp.; henceforth, PDs). Adult ferrets are sexually dimorphic and PDs are of similar size making them a difficult prey item....

2024, Anthropocene (45)
The United States (U.S.) coastal plain is subject to rising sea levels, land subsidence, more severe coastal storms, and more intense droughts. These changes lead to inputs of marine salts into freshwater-dependent coastal systems, creating saltwater intrusion. The penetration of salinity...
Does daily activity overlap of seven mesocarnivores vary based on human development?
Leah McTigue, Ellery V. Lassiter, Mike Shaw, Emily Johansson, Ken Wilson, Brett Alexander DeGregorio
2024, PLoS ONE (19)
Many species of wildlife alter their daily activity patterns in response to co-occurring species as well as the surrounding environment. Often smaller or subordinate species alter their activity patterns to avoid being active at the same time as larger, dominant species to avoid agonistic interactions. Human development can complicate interspecies...

Sandra O. Brugger, Nathan J. Chellman, Andreas Plach, Paul D. Henne, Andreas Stohl, Joseph R. McConnell
2024, Geophysical Research Letters (51)
Rapid warming and human exploitation threaten boreal forests. Understanding links among vegetation, climate, and people in this vast biome requires highly resolved long-term records that integrate regional inputs. We developed an 850-year pollen-based record of supraregional vegetation change using a southern Greenland ice core and atmospheric modeling...
Stable isotopes reveal intertidal fish and crabs use bivalve farms as foraging habitat in Puget Sound, Washington
Karl Veggerby, Mark David Scheuerell, Beth Sanderson, Peter Kiffney
2024, Frontiers in Marine Science (10)
Bivalves such as oysters and clams have been farmed in intertidal zones across the Puget Sound region of the Salish Sea for thousands of years. The variety of gear types used on bivalve farms creates complex vertical structure and attachment points for aquatic epiphytes and invertebrates which increases habitat structural...

Michael N. Fienen, Nicholas Corson-Dosch, Kalle Jahn, Jeremy T. White
2024, Environmental Modelling & Software (173)
Groundwater flow and particle tracking models are critical tools to simulate the natural system, contaminant fate and transport, and effects of remediation. Constrained optimization uses models to systematically explore the interplay between remedial design and contaminant fate, considering uncertainty. Sequential Linear Programming (SLP) provides a design alternative addressing a single goal (e.g. maximum...

Machine learning approaches to identify lithium concentration in petroleum produced waters
E. D. Attanasi, Timothy Coburn, Philip A. Freeman
2024, Mineral Economics (37) 477-497
Prices for battery-grade lithium have increased substantially since 2020, which is propelling the search for additional sources of this important element. Battery-grade lithium is predominately recovered from continental brines. Most crude oil and natural gas wells recover briny formation water, which may represent an additional source. Chemical analysis of these...

Comparing maximum likelihood and Bayesian methods for fitting hidden Markov models to multi-state capture-recapture data of invasive carp in the Illinois River
Charles J. Labuzzetta, Alison A. Coulter, Richard A. Erickson
2024, Ecology Movement (12)
BackgroundHidden Markov Models (HMMs) are often used to model multi-state capture-recapture data in ecology. However, a variety of HMM modeling approaches and software exist, including both maximum likelihood and Bayesian methods. The diversity of these methods obscures the underlying HMM and can exaggerate minor differences in parameterization.<h3 class="c-article__sub-heading"...

2024, Journal of Advances in Modeling Earth Systems (16)
As interfaces connecting terrestrial and ocean ecosystems, coastal wetlands develop temporally and spatially complex redox conditions, which drive uncertainties in greenhouse gas emission as well as the total carbon budget of the coastal ecosystem. To evaluate the role of complex redox reactions in methane emission from coastal...
