Lauren Swam, Megan K. La Peyre, Brian Callam, Jerome F. La Peyre
2022, North American Journal of Aquaculture (84) 381-391
Eastern oysters Crassostrea virginica support a critical commercial industry and provide many ecosystem services to coastal estuaries yet are currently threatened by changing estuarine conditions. A changing climate and the effects of river and coastal management are altering freshwater inflows into productive oyster areas, causing more frequent and extreme salinity exposure. Although...

Are you sleeping? Are you sleeping? Predicting invasion potential of sleeper species
Ayodele O’Uhuru, Audrey Barker-Plotkin, Justin Dalaba, Will Pfadenhauer, Amanda Suzzi, Toni Lyn Morelli
2022, Report
Sleeper species are non-native species that are established in a region and could become invasive as climate change makes conditions more favorable for many non-native species. Before we can manage potential sleepers, we must first know their identity. We analyzed non-native, established plants in the Northeast United States (CT, MA,...

Forest and nonforest ecosystems of the western United States are experiencing major transformations in response to land-use change, climate warming, and their interactive effects with wildland fire. Some ecosystems are transitioning to persistent alternative types, hereafter called “vegetation type conversion” (VTC). VTC is one of the most pressing management issues...
Long-term change in metabolism phenology in north temperate lakes
Robert Ladwig, Alison P. Appling, Austin D. Delany, Hilary A. Dugan, Qiantong Gao, Noah R. Lottig, Jemma Stachelek, Paul C. Hanson
2022, Limnology and Oceanography (67) 1502-1521
The phenology of dissolved oxygen (DO) dynamics and metabolism in north temperate lakes offers a basis for comparing metabolic cycles over multi-year time scales. Although proximal control over lake DO can be attributed to metabolism and physical processes, how those processes evolve over decades largely remains unexplored. Metabolism phenology may...
Late Holocene human-environment interactions on the central California coast, USA, inferred from Morro Bay salt marsh sediments
Ellie Broadman, Liam M. Reidy, David Wahl
2022, Anthropocene (38)
Coastal salt marshes and estuaries provide valuable ecosystem services, yet are susceptible to alteration from human activities. Records of past environmental change in these ecosystems can elucidate relationships between human activities, such as land-use practices, and physical and ecological processes, such as sediment accretion...

Gregory E. Noe, Kristina G. Hopkins, Peter Claggett, Edward R. Schenk, Marina J. Metes, Labeeb Ahmed, Thomas Rossiter Doody, Cliff R. Hupp
2022, Environmental Research Letters (17)
Stream geomorphic change is highly spatially variable but critical to landform evolution, human infrastructure, habitat, and watershed pollutant transport. However, measurements and process models of streambank erosion and floodplain deposition and resulting sediment fluxes are currently insufficient to predict these rates in all perennial streams over large...

2022, PLoS Pathogens (18)
The diversity of influenza A viruses (IAV) is primarily hosted by two highly divergent avian orders: Anseriformes (ducks, swans and geese) and Charadriiformes (gulls, terns and shorebirds). Studies of IAV have historically focused on Anseriformes, specifically dabbling ducks, overlooking the diversity of hosts in nature, including...

For many avian species, spatial migration patterns remain largely undescribed, especially across hemispheric extents. Recent advancements in tracking technologies and high-resolution species distribution models (i.e., eBird Status and Trends products) provide new insights into migratory bird movements and offer a promising opportunity for integrating independent data...
Whooping and sandhill cranes visit upland ponds proportional to migration phenology on the Texas coast
Matthew J Butler, Kristine L. Metzger, Colt R. Sanspree, James W. Cain III, Grant M Harris
2022, Wildlife Society Bulletin (46)
Two crane species, whooping cranes (Grus americana) and sandhill cranes (Antigone canadensis), overwinter along the Texas Gulf Coast. Periodic, extreme drought conditions have prompted concerns that potential freshwater limitations could hinder conservation of cranes, especially endangered whooping cranes. In response, land managers constructed and...

Changes in waterfowl migration phenologies in central North America: Implications for future waterfowl conservation
Kent Andersson, Craig A. Davis, Grant Harris, David A. Haukos
2022, PLoS ONE (17)
Globally, migration phenologies of numerous avian species have shifted over the past half-century. Despite North American waterfowl being well researched, published data on shifts in waterfowl migration phenologies remain scarce. Understanding shifts in waterfowl migration phenologies along with potential drivers is critical for guiding future conservation efforts. Therefore, we utilized...

Accelerated sea-level rise is suppressing CO2 stimulation of tidal marsh productivity: A 33-year study
Chunwu Zhu, J. Adam Langley, Lewis H. Ziska, Donald Cahoon, J. Patrick Megonigal
2022, Science Advances (8)
Accelerating relative sea-level rise (RSLR) is threatening coastal wetlands. However, rising CO2 concentrations may also stimulate carbon sequestration and vertical accretion, counterbalancing RSLR. A coastal wetland dominated by a C3 plant species was exposed to ambient and elevated levels of CO2 in situ from 1987 to 2019 during which time ambient CO2 concentration increased...
Variation of cisco egg size among Laurentian Great Lakes populations
Scott T Koenigbauer, Daniel L. Yule, Kristopher Dey, Chris Olds, Michael J. Connerton, Tomas O Hook
2022, Journal of Great Lakes Research (48) 790-797
Many fish species display inter-population and inter-individual egg size variation. Intra-specific differences in egg size seemingly reflect both energetic experiences of individual spawning fish and long-term population responses to differing ecosystems. Optimal egg size theory implies that selection influences a population’s mean egg size in response to its early-life environment,...

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...
Hot spots and hot moments in the Critical Zone: Identification of and incorporation into reactive transport models
Bhavna Arora, Martin Briggs, Jay P. Zarnetske, James Stegen, Jesus Gomez-Velez, D. Dwivedi
2022, Book chapter, Biogeochemistry of the Critical Zone
Biogeochemical processes are often spatially discrete (hot spots) and temporally isolated (hot moments) due to variability in controlling factors like hydrologic fluxes, lithological characteristics, bio-geomorphic features, and external forcing. Although these hot spots and hot moments (HSHMs) account for a high percentage of carbon, nitrogen and nutrient cycling within the...
Velocity modeling of supercritical pore fluids through porous media under reservoir conditions with applications for petroleum secondary migration and carbon sequestration plumes
Lauri A. Burke
2022, SEG-AAPG Interpretation (10) SG1-SG9
Computational methods to characterize secondary migration in porous media traditionally rely on fluid transport equations with assumptions of time invariance, such as flowpath modeling of buoyancy vectors, statistical percolation algorithms, capillary pressure curves, or a form of Darcy’s Law which presumes instantaneous fluid transport. However, in petroleum systems modeling, the...
