Assessment of multiple ecosystem metabolism methods in an estuary
Luke C. Loken, Erwin E Van Nieuwenhuyse, Randy A Dahlgren, Leah Kammel, Paul Stumpner, Jon R. Burau, Steven Sadro
2021, Limnology & Oceanography: Methods (19) 741-757
Ecosystem metabolism is a key ecological attribute and easy to describe, but quantifying metabolism in estuaries is challenging. Properly scaling measurements through time and space requires consideration of hydrodynamics and mixing water from heterogeneous sources, making any estimation uncertain. Here, we compared three methods for modeling...
Structured decision making and optimal bird monitoring in the northern Gulf of Mexico
Auriel Fournier, R. Randy Wilson, James E. Lyons, Jeffrey S. Gleason, Evan M. Adams, Laurel M. Barnhill, Janell M. Brush, Robert J. Cooper, Stephen J. DeMaso, Melanie J.L. Driscoll, Mitchell J. Eaton, Peter C. Frederick, Michael G. Just, Michael A. Seymour, John M. Tirpak, Mark S. Woodrey
2021, Open-File Report 2020-1122
The avian conservation community struggles to design and implement large scale, long-term coordinated bird monitoring programs within the northern Gulf of Mexico due to the complexity of the conservation enterprise in the region; this complexity arises from the diverse stakeholders, multiple jurisdictions, complex ecological processes, myriad habitats, and over 500...
Replacement of the typical artedi form of Coregonus artedi in Lake Huron by endemic shallow-water Ciscoes, including putative hybrids
Randy L. Eshenroder, Yu-Chun Kao, Timothy P. O’Brien, Chris M. Olds, Chris L. Davis, Alexander T. Duncan
2021, Transactions of the American Fisheries Society (150) 792-806
Various ecomorphs of shallow-water Cisco Coregonus artedi were the dominant fish planktivores in each of the Great Lakes until invasive species and over fishing resulted in extirpations and extinctions. In this paper we describe the present morphological diversity and distribution of shallow-water Ciscoes in each of Lake Huron’s...
Climate impacts on source contributions and evaporation to flow in the Snake River Basin using surface water isoscapes (δ2H and δ18O)
Grace Windler, J. Renee Brooks, Henry M. Johnson, Randy Comeleo, Rob Coulombe, Gabriel J. Bowen
2021, Water Resources Research (57)
Rising global temperatures are expected to decrease the precipitation amount that falls as snow, causing greater risk of water scarcity, groundwater overdraft, and fire in areas that rely on mountain snowpack for their water supply. Streamflow in large river basins varies with the amount, timing, and type of precipitation, evapotranspiration,...
Amplified impact of climate change on fine-sediment delivery to a subsiding coast, Humboldt Bay, California
Jennifer Curtis, Lorraine E. Flint, Michelle A. Stern, Jack Lewis, Randy D. Klein
2021, Estuaries and Coasts (44) 2173-2193
In Humboldt Bay, tectonic subsidence exacerbates sea-level rise (SLR). To build surface elevations and to keep pace with SLR, the sediment demand created by subsidence and SLR must be balanced by an adequate sediment supply. This study used an ensemble of plausible future scenarios to predict potential climate change impacts...
Remote ecological monitoring with smartphones and tasker
Therese M. Donovan, Cathleen Balantic, Jonathan Katz, Mark Massar, Randy Knutson, Kara Duh, Peter Jones, Keith Epstein, Julien Lacasse-Roger, João Dias
2021, Journal of Fish and Wildlife Management (12) 163-173
Researchers have increasingly used autonomous monitoring units to record animal sounds, track phenology with timed photographs, and snap images when triggered by motion. We piloted the use of smartphones to monitor wildlife in the Riverside East Solar Energy Zone (California) and at Indiana Dunes National Park (Indiana). For both efforts,...
Contrasting geographic patterns of ignition probability and burn severity in the Mojave Desert
Robert C. Klinger, Emma C Underwood, Randy McKinley, Matthew L. Brooks
2021, Frontiers in Ecology and Evolution (9)
The extent and frequency of fire has increased in many arid systems over the last century, with a large proportion of area in some regions undergoing transitions to novel conditions. Portions of the Mojave Desert in southwestern North America have undergone such transitions, most often from woody to...

Artificial nightlight is increasingly recognized as an important environmental disturbance that influences the habitats and fitness of numerous species. However, its effects on wide‐ranging vertebrates and their interactions remain unclear. Light pollution has the potential to amplify land‐use change, and as such, answering the question of how this sensory stimulant...

Mississippi Alluvial Valley Forest-breeding landbird population & quantitative habitat objectives
Dean W. Demarest, Blaine Elliott, Robert Ford, David Hanni, S. Keith McKnight, Anne E. Mini, Daniel J. Twedt, R. Randy Wilson
2020, Report
The Mississippi Alluvial Valley (MAV) is a 9 million ha (22-million-acre) floodplain that supports a diverse and ecologically rich bottomland hardwood forest ecosystem – one of the most productive in North America. It extends from roughly Cape Girardeau, Missouri, to the Gulf of Mexico and features a mosaic of ridges,...

Daniel S. Donnelly, Vanessa R. von Biela, Stephen D. McCormick, Sarah M. Laske, Michael P. Carey, Shannon C. Waters-Dynes, Lizabeth Bowen, Randy J Brown, Sean Larson, Christian E. Zimmerman
2020, Conservation Physiology (1)
Manipulative experiments provide stronger evidence for identifying cause-and-effect relationships than correlative studies, but protocols for implementing temperature manipulations are lacking for large species in remote settings. We developed an experimental protocol for holding adult Chinook salmon (Oncorhynchus tshawytscha) and exposing them to elevated temperature treatments. The goal of the...
Transcriptomic response to elevated water temperatures in adult migrating Yukon River Chinook salmon (Oncorhynchus tshawytscha)

2020, Conservation Physiology (8)
Chinook salmon (Oncorhynchus tshawytscha) declines are widespread and may be attributed, at least in part, to warming river temperatures. Water temperatures in the Yukon River and tributaries often exceed 18°C, a threshold commonly associated with heat stress and elevated mortality in Pacific salmon. Untangling the complex web of direct...

2020, Canadian Journal Fisheries and Aquatic Sciences (77) 1878-1892
Migrating adult Pacific salmon (Oncorhynchus spp.) are sensitive to warm water (>18 °C), with a range of consequences from decreased spawning success to early mortality. We examined the proportion of Yukon River Chinook salmon (O. tshawytscha) exhibiting evidence of heat stress to assess the potential that high temperatures contribute to freshwater...

Context Since 2005, unconventional gas develop[1]ment has rapidly altered forests across the Marcellus[1]Utica shale basin in the central Appalachian region of the eastern United States, an area of high conservation value for biodiversity. Much is still unknown about ecological impacts of associated land cover change. Objectives Our goal was to...
Describing historical habitat use of a native fish-Cisco (Coregonus artedi)-In Lake Michigan between 1930 and 1932
Yu-Chun Kao, David Bunnell, Randy L. Eshenroder, Devin N. Murray
2020, PLoS ONE (15)
With the global-scale loss of biodiversity, current restoration programs have been often required as part of conservation plans for species richness and ecosystem integrity. The restoration of pelagic-oriented cisco (Coregonus artedi) has been an interest of Lake Michigan managers because it may increase the diversity and resilience of the fish...

Biogenic coal-to-methane conversion can be enhanced with small additions of algal amendment in field-relevant upflow column reactors
Katherine J. Davis, George A. Platt, Elliott Barnhart, Randy Hiebart, Robert Hyatt, Matthew W. Fields, Robin Gerlach
2019, Fuel (256)
ubsurface coal environments, where biogenic coal-to-methane conversion occurs, are difficult to access, resulting in inherent challenges and expenses for in situexperiments. Previous batch reactor studies provided insights into specific processes, pathways, kinetics, and engineering strategies, but field-relevance is restricted due to limited substrate availability or byproduct accumulation that may influence reactions...

Context: Diadromous fish populations in the Pacific Northwest face challenges along their migratory routes from declining habitat quality, harvest, and barriers to longitudinal connectivity. These stressors complicate the prioritization of proposed management actions intended to improve conditions for migratory fishes including anadromous salmon and trout. Objectives: We describe a multi-scale hybrid...
