Bethan Davies, Jacob Bendle, Jonathan Carrivick, Robert McNabb, Christopher J. McNeil, Mauri Pelto, Seth Campbell, Tom Holt, Jeremy Ely, Bradley Markle
2022, Earth Surfaces Processes and Landforms (47) 2357-2390
Globally, mountain glaciers and ice caps are losing dramatic volumes of ice. The resultant sea-level rise is dominated by contributions from Alaska. Plateau icefields may be especially sensitive to climate change due to the non-linear controls their topography imparts on their response to climate change. However, Alaskan plateau icefields have...
Sandhill crane colt survival in Minnesota
William J. Severud, David Wolfson, John Fieberg, David E. Andersen
2022, Journal of Fish and Wildlife Management (13) 494-501
Age-structured population models require reliable estimates of cohort-specific survival rates, yet vital rates of younger age classes are often difficult to estimate because of the logistical challenges of monitoring young animals. As part of a study of sandhill cranes Antigone canadensis in the zone of contact between breeding distributions of the Eastern...

Abigail Lynch, Frank J. Rahel, Douglas Limpinsel, Suresh Sethi, Agustin C. Engman, David J. Lawrence, Katherine E. Mills, Wendy Morrison, Jay O. Peterson, Mark T. Porath
2022, Fisheries Management and Ecology (29) 329-345
Fisheries management is a complex task made even more challenging by rapid and unprecedented socioecological transformations associated with climate change. The Resist-Accept-Direct (RAD) framework can be a useful tool to support fisheries management in facing the high uncertainty and variability associated with aquatic ecosystem transformations. Here, RAD strategies are presented...

2022, Journal of Ecology (110) 1615-1631
Drylands have low nitrogen stocks and are predicted to be sensitive to modest increases in reactive nitrogen availability, but direct evidence that atmospheric nitrogen deposition will have sustained effects on dryland ecosystems is sparse and conflicting.We used three long-running in situ nitrogen deposition simulation experiments and a complementary laboratory incubation experiment...
Neuroendocrine regulation of plasma cortisol levels during smoltification and seawater acclimation of Atlantic salmon
Brett M Culbert, Amy M. Regish, Daniel J Hall, Stephen D. McCormick, Nicholas J. Bernier
2022, Frontiers in Endocrinology (13)
Diadromous fishes undergo dramatic changes in osmoregulatory capacity in preparation for migration between freshwater and seawater. One of the primary hormones involved in coordinating these changes is the glucocorticoid hormone, cortisol. In Atlantic salmon (Salmo salar), cortisol levels increase during the spring smoltification period prior to seawater migration; however, the...

2022, Journal of Maps (18) 352-361
Agriculture is a key element of Afghanistan’s economy and plays an essential role supporting the expanding population and urban development of Kabul, the country’s capital. Over the past decades the urban landscape has changed substantially and agricultural land use has shifted in its extent, location, and density. Identifying trends in...
The applicability of time-integrated unit stream power for estimating bridge pier scour using noncontact methods in a gravel-bed river
Laura A. Hempel, Helen F. Malenda, John W, Fulton, Mark F. Henneberg, Jay Cederberg, Tommaso Moramarco
2022, Remote Sensing (14)
In near-field remote sensing, noncontact methods (radars) that measure stage and surface water velocity have the potential to supplement traditional bridge scour monitoring tools because they are safer to access and are less likely to be damaged compared with in-stream sensors. The objective of this study was to evaluate the...

Jonathan D. Cook, Evan H. Campbell Grant, Jeremy T. H. Coleman, Jonathan M. Sleeman, Michael C. Runge
2022, Wildlife Society Bulletin (46)
Preventing wildlife disease outbreaks is a priority for natural resource agencies, and management decisions can be urgent, especially in epidemic circumstances. With the emergence of SARS-CoV-2, wildlife agencies were concerned whether the activities they authorize might increase the risk of viral transmission from humans to North American bats, but had...

Identification of supraoptimal temperatures in juvenile blueback herring (Alosa aestivalis) using survival, growth rate and scaled energy reserves
Lian Guo, Adrian Jordaan, Eric T. Schultz, Stephen D. McCormick
2022, Conservation Physiology (10)
For young fishes, growth of somatic tissues and energy reserves are critical steps for survival and progressing to subsequent life stages. When thermal regimes become supraoptimal, routine metabolic rates increase and leave less energy for young fish to maintain fitness-based activities and, in the case of anadromous fishes, less...

Population viability analysis for a pond-breeding amphibian under future drought scenarios in the southeastern United States
Brian A. Crawford, John C. Maerz, Vanessa C. K. Terrell, Clinton T. Moore
2022, Global Ecology and Conservation (36)
Climate change effects are contributing to widespread declines of amphibians, and pond-breeding species may be particularly sensitive to future drought conditions that restrict wetland hydroperiods and decrease opportunities for successful breeding and recruitment. Pond-breeding amphibian populations can compensate for periodic droughts via episodic booms in recruitment,...
Pre-breeding foraging ecology of three tern species nesting in the Gulf of Maine
Rachel M. Bratton, Henry Legett, Paula Shannon, Keenan Yakola, Alexander R. Gerson, Michelle Staudinger
2022, Avian Conservation and Ecology (17)
A variety of seabird species migrate annually from wintering grounds in the Southern Hemisphere to the Gulf of Maine, USA to breed and raise their young. Post-migration, adult seabirds depend on the spatio-temporal match of reliable food resources to replenish energy reserves before breeding. However, the conditions during this critical...

Prolonged drought due to climate change has negatively impacted amphibians in southern California, U.S.A. Due to the severity and length of the current drought, agencies and researchers had growing concern for the persistence of the arroyo toad (Anaxyrus californicus), an endangered endemic amphibian in this region. Range-wide surveys for this...
Sensitivity of headwater streamflow to thawing permafrost and vegetation change in a warming Arctic
Joshua C. Koch, Ylva Sjoberg, Jonathan A. O’Donnell, Michael P. Carey, Pamela Sullivan, A. Terskaia
2022, Environmental Research Letters (17)
Climate change has the potential to impact headwater streams in the Arctic by thawing permafrost and subsequently altering hydrologic regimes and vegetation distribution, physiognomy and productivity. Permafrost thaw and increased subsurface flow have been inferred from the chemistry of large rivers, but there is limited empirical evidence of the impacts...

Extreme rainstorms drive exceptional organic carbon export from forested humid-tropical rivers in Puerto Rico
Kasey E. Clark, Robert Stallard, Sheila F. Murphy, Martha A. Scholl, Grizelle Gonzalez, Alain F. Plante, William H. McDowell
2022, Nature Communications (13)
Extreme rainfall events in the humid-tropical Luquillo Mountains, Puerto Rico export the bulk of suspended sediment and particulate organic carbon. Using 25 years of river carbon and suspended sediment data, which targeted hurricanes and other large rainstorms, we estimated biogenic particulate organic carbon yields of 65 ± 16...
