Potential corrosivity of untreated groundwater in Louisiana
Angela L. Robinson
2024, Scientific Investigations Report 2024-5035
Corrosive groundwater can cause lead, copper, and other metals to leach from pipes and plumbing fixtures in water distribution systems. Metals, if ingested, could lead to serious health implications to the nearly 2.9 million people in Louisiana who obtain their drinking water from groundwater sources. Four indices—the Langelier Saturation Index...

James R. Hein, Kira Mizell, Amy Gartman
2024, Geochemistry, Geophysics, Geosystems (25)
Rocks dredged from water depths of 1,605, 2,500, 3,300, and 3,400 m in the Arctic Ocean included Paleozoic continental rocks pervasively mineralized during the Neogene by hydrothermal Fe and Mn oxides. Samples were recovered in three dredge hauls from the Chukchi Borderland and one from Mendeleev Ridge north of Alaska and...
Assessing and implementing the concept of Blue Economy in Laurentian Great Lakes fisheries: Lessons from coupled human and natural systems
Andrew Kenneth Carlson, Nancy J. Leonard, Mohiuddin Munawar, William W. Taylor
2024, Aquatic Ecosystem Health & Management (27) 74-84
Inland fisheries often receive little to no attention in global discussions about sustainable development. The consequences of overlooking inland fisheries in sustainability dialogues are increasingly problematic as fisheries stressors (e.g., overharvest, species invasion, climate change, habitat modification) intensify. Elevating the global profile of inland fisheries requires an approach for quantifying...
Insights on arc magmatic systems drawn from natural melt inclusions and crystallization experiments at PH2O=800 MPa under oxidizing conditions
Janine L. Andrys, Elizabeth Cottrell, Katherine A. Kelley, Laura E. Waters, Michelle L. Coombs
2024, Journal of Petrology (65)
Whole rock compositions at Buldir Volcano, western Aleutian arc, record a strong, continuous trend of iron depletion with decreasing MgO, classically interpreted as a calc-alkaline liquid line of descent. In contrast, olivine-hosted melt inclusions have higher total iron (FeO*) than whole rocks and show little change in FeO* with decreasing...
River suspended-sand flux computation with uncertainty estimation using water samples and high-resolution ADCP measurements
Jessica Marggraf, Guillaume Dramais, Jerome Le Coz, Blaise Calmel, Benoit Camenen, David J. Topping, William Santini, Gilles Pierrefeu, François Lauters
2024, Earth Surface Dynamics (12) 1243-1266
Measuring suspended-sand fluxes in rivers remains a scientific challenge due to their high spatial and temporal variability. To capture the vertical and lateral gradients of concentration in the cross-section, measurements with point samples are performed. However, the uncertainty related to these measurements is rarely evaluated, as few studies of the...
Reducing uncertainty with iterative model updating parses effects of competition and environment on salamander occupancy
Jo Avital Werba, Graziella Vittoria DiRenzo, Adrianne Brand, Evan H. Campbell Grant
2024, Oecologia (206) 305-316
Making timely management decisions is often hindered by uncertainty. Monitoring reduces two key types of uncertainty. First, it serves to reduce structural uncertainty of how the system works and provides support for expectations of how a system works. Second, it serves to reduce parametric uncertainty of the drivers of system...
Ceanothus: Taxonomic patterns in life history responses to fire
Jon Keeley, V. Thomas Parker, Paul H. Zedler, R. Brandon Pratt
2024, American Journal of Botany (111)
Premise: Ceanothus (Rhamnaceae) is a large genus of shrubs that dominate California chaparral and are resilient to fires. Persistence is ensured by resprouting and/or seedling recruitment from dormant seed banks. Some species do both and others, the obligate seeders, are entirely dependent on seedling recruitment. The distribution of these two modes...

J.K. Craig, K.I. Siegfried, R.T. Cheshire, M. Karnauskas, Patrick G.R. Jodice
2024, Regional Studies in Marine Science (80)
The U.S. South Atlantic coastal region is used by many marine birds for foraging, reproduction, and migration. We developed standardized indices of relative abundance from long–term (1980–2016), semi-structured monitoring data (eBird) for eight species: Brown Pelican (Pelecanus occidentalis), Double-Crested Cormorant (Nannopterum auritum), White Ibis (Eudocimus albus), Wood Stork (Mycteria americana),...

2024, STAC Workshop Report 24-006
The Chesapeake Bay Program’s (CBP) Science and Technical Advisory Committee (STAC) organized and led a workshop on the science and practice of stream restoration in order to summarize the state of knowledge in order to identify ways to improve stream restoration outcomes. The workshop identified a general framework for explaining...
Individual return patterns of spawning flannelmouth sucker (Catostomus latipinnis) to a desert river tributary
Sophia Marie Bonjour, Keith B. Gido, Charles N. Cathcart, Mark C. McKinstry
2024, Scientific Reports (14)
Tributaries provide temporal and spatial habitat heterogeneity in river networks that can be critical for parts of the life history of a species. Tributary fidelity can benefit individual fish undergoing spawning migrations by reducing time and energy spent exploring new areas and leveraging previous experience, but anthropogenic activities that fragment...
A new water temperature modeling approach to predict thermal habitat suitability for nonnative cichlids in Florida rivers
Alexandra M. Scott, Andrew Kenneth Carlson
2024, Journal of Freshwater Ecology (39)
As global temperatures increase, the spatiotemporal arrangement of thermal habitats in Florida rivers may shift, creating the potential for greater dispersal and establishment of nonnative tropical freshwater fishes. To understand how water temperature changes may affect the spatial distribution of these nonnative species, more effective water temperature prediction models are...

Jonathan P. Rose, Lorraine S Parsons, Patrick M. Kleeman, Brian J. Halstead
2024, Ecological Restoration (42) 271-283
Non-native plants can affect communities through direct competition, and by providing refuge to seed predators, creating apparent competition with native plants. Ammophila arenaria (European beachgrass) has been introduced to coastal dune habitats throughout the western United States where it forms dense monocultures, stabilizes dunes, and alters abiotic and biotic conditions....

Connor Reeve, Jean V. Adams, Scott M. Miehls, Michael R. Lowe, Steven J. Cooke, Mary L. Moser, Jake W. Brownscombe
2024, Transactions of American Fisheries Society (153) 781-801
ObjectiveSea Lamprey Petromyzon marinus remain problematic for Lake Trout Salvelinus namaycush restoration in the Laurentian Great Lakes. Fisheries assessments would benefit from knowledge of spatial–temporal patterns of Sea Lamprey parasitism on Lake Trout; however, such patterns are challenging to estimate from wounding rates on caught Lake...

Brian G. Prochazka, Carl Gregory Lundblad, Kevin E. Doherty, Shawn T. O’Neil, John C. Tull, Steve C. Abele, Cameron L. Aldridge, Peter S. Coates
2024, Rangeland Ecology & Management (97) 146-159
Sagebrush ecosystems support a suite of unique species such as the emblematic greater sage-grouse (Centrocercus urophasianus; sage-grouse) but are under increasing pressure from anthropogenic stressors such as annual grass invasion, conifer encroachment, altered wildfire regimes, and land use change. We examined the ability of an ecosystem-based framework for sagebrush conservation,...

Erin Kay Benson, Kathryn E. Watts
2024, Economic Geology (119) 1611-1642
The largest rare earth element (REE) deposit in the United States is a carbonatite intrusion at Mountain Pass in the Mojave Desert, California. Despite a clear spatiotemporal association of alkaline silicate and carbonatite intrusions at Mountain Pass, a genetic model of their mutual formation has not been resolved. The Mountain...

2024, Freshwater Biology (69) 1583-1595
1. Spawning Pacific salmon (Oncorhynchus spp.) provide marine-derived resources (MDR) to freshwater food webs in the form of eggs, flesh and maggots that consume salmon carcasses, all of which positively impact stream-dwelling fish growth. Pink salmon (O. gorbuscha) are widely distributed throughout coastal catchments along the North Pacific Ocean and display increased...

One of the world’s largest “blue carbon” ecosystems, Louisiana’s tidal wetlands on the US Gulf of Mexico coast, is rapidly being lost. Louisiana’s strong legal, regulatory, and monitoring framework, developed for one of the world’s largest tidal wetland systems, provides an opportunity for a programmatic approach to blue carbon accreditation...
