Natural and anthropogenic influences on benthic cyanobacteria in streams of the northeastern United States
Nicholas O. Schulte, Daren M. Carlisle, Sarah Spaulding
2022, Science of the Total Environment (826)
Benthic cyanobacteria are widespread in streams and rivers and have the potential to release toxins. In large numbers, these microorganisms and their toxins present a risk to human health. Cyanobacterial abundance in stream biofilms is typically related to single or a limited set of...
Limited land base and competing land uses force societal tradeoffs when siting energy development
Jill A. Shaffer, Neal D. Niemuth, Charles R. Loesch, Clayton E. Derby, Aaron T. Pearse, Kevin W. Barnes, Terry L. Shaffer, Adam J. Ryba
2022, Journal of Fish and Wildlife Management (13) 106-123
As human populations grow, decisions regarding use of the world's finite land base become increasingly complex. We adopted a land use–conflict scenario involving renewable energy to illustrate one potential cause of these conflicts and resulting tradeoff decisions. Renewable energy industries wishing to expand operations in the United States are limited...

Comparison of methods for estimating density and population trends for low-density Asian bears
Dana J. Morin, John Boulanger, Richard Bischof, David C. Lee, Dusit Ngoprasert, Angela K. Fuller, Bruce McLellan, Robert Steinmetz, Sandeep Sharma, Dave Garshelis, Arjun M. Gopalaswamy, Muhammad Ali Nawaz, Ullas Karanth
2022, Global Ecology and Conservation
Populations of bears in Asia are vulnerable to extinction and effective monitoring is critical to measure and direct conservation efforts. Population abundance (local density) or growth (λ) are the most sensitive metrics to change. We discuss the value in implementing spatially explicit capture-recapture (SCR), the current gold standard for density estimation,...
Drivers of flight performance of California Condors (Gymnogyps californianus)
Sophie R. Bonner, Sharon A. Poessel, Joseph C. Brandt, Molly T. Astell, James R. Belthoff, Todd E. Katzner
2022, Journal of Raptor Research (56) 17-27
Flight behavior of soaring birds depends on a complex array of physiological, social, demographic, and environmental factors. California Condors (Gymnogyps californianus) rely on thermal and orographic updrafts to subsidize extended bouts of soaring flight, and their soaring flight performance is expected to vary in response to environmental variation and, potentially,...
Water chemistry, exposure routes and metal forms determine the bioaccumulation dynamics of silver (ionic and nanoparticulate) in Daphnia magna
Emma Lesser, Fatima Noor Sheikh, Mithun Sikder, Marie Noele Croteau, Natasha Franklin, Mohammed Baalousha, Niveen S. Ismail
2022, Environmental Toxicology and Chemistry (41) 726-738
Treatment wetlands utilize various physical and biological processes to reduce levels of organic contaminants, metals, bacteria, and suspended solids. Silver nanoparticles (AgNPs) are one type of contaminant that can enter treatment wetlands and impact the overall treatment efficacy. Grazing by filter-feeding zooplankton, such as Daphnia magna, is critical to treatment wetland...

Old Mine Park, in the northern Trumbull area (also known as Long Hill) of southwestern Connecticut, is a recreation area encompassing the mineral-rich hill of “Saganawamps” and owned by the Town of Trumbull. Most of its 72 acres are wooded, rocky and undeveloped but it is surrounded by dense infrastructure...
Synthetic aperture radar volcanic flow maps (SAR VFMs): A simple method for rapid identification and mapping of volcanic mass flows
Michael Poland
2022, Bulletin of Volcanology (84)
Volcanic mass flows, including lava, pyroclastic density currents, and lahars, account for the bulk of fatalities and infrastructure damage caused by volcanic eruptions. Mapping these flows soon after their emplacement is vital to understanding their impact and to forecasting the likely behavior of potential future flows. Synthetic aperture radar (SAR)...
Rotenone use and subsequent prey loss lowers Osprey fledging rates via brood reduction
Charles J. Henny, James L Kaiser
2022, Journal of Raptor Research (56) 37-54
Fisheries managers used the fish toxicant rotenone to eradicate an undesirable brown bullhead (Ameiurus nebulosus) population and all other fish species at Hyatt Reservoir, Oregon, on 12 October 1989. This 4-yr study (1988–1990, 1992) compared effects of that rotenone project on Ospreys (Pandion haliaetus) nesting...

Jian Shen, Jiabi Du, Lisa Lucas
2022, Limnology and Oceanography (67) 918-933
Simple mathematical models are derived from mass balances for water and transported substance to provide insight into the relationships between import, export, transport, and internal removal for nonconservative substances in an estuary. Extending previous work, our models explicitly include water and substance inputs from the ocean...

Andre S. Rovai, Robert R. Twilley, Alexandra Christiensen, Annabeth McCall, Daniel J. Jensen, Gregg Snedden, James T. Morris, John A. Cavell
2022, Estuarine, Coastal and Shelf Science (268)
Deltaic floodplains are highly vulnerable to relative sea level rise (RSLR) depending on the sediment supply from river channels that provides elevation capital as adaptation mechanism. In river channels where levees have restricted sediment supply to coastal deltaic floodplains, river sediment diversions have been proposed as a restoration strategy to...

Hydropower production is one of the greatest threats to fluvial ecosystems and freshwater biodiversity. Now that we have entered the Anthropocene, there is an opportunity to reflect on what might constitute a ‘sustainable’ Anthropocene in the context of hydropower and riverine fish populations. Considering elements of existing practices that promote favorable...

Kendra Spence Cheruvelil, Katherine Webster, Katelyn King, Autumn C. Poisson, Tyler Wagner
2022, Hydrobiologia (849) 3663-3677
We conducted a macroscale study of 2210 shallow lakes (mean depth ≤ 3 m or a maximum depth ≤ 5 m) in the Upper Midwestern and Northeastern USA. We asked the following: What are the patterns and drivers of shallow lake total phosphorus (TP), chlorophyll a (CHLa), and TP–CHLa relationships at the macroscale, how do these differ from...

Jiaojiao Diao, Jinxun Liu, Zhiliang Zhu, Xinyuan Wei, Mingshi Li
2022, Forest Ecosystems (9)
BackgroundChina has committed to achieving peak CO2 emissions before 2030 and carbon neutrality before 2060; therefore, accelerated efforts are needed to better understand carbon accounting in industry and energy fields as well as terrestrial ecosystems. The carbon sink capacity of plantation forests contributes to the mitigation of climate...

Comparison of sediment composition by smear slides to quantitative shipboard data: A case study on the utility of smear slide percent estimates, IODP Expedition 353, northern Indian Ocean
Stephen C. Phillips, Kate Littler
2022, Scientific Drilling (30) 59-74
Smear slide petrography has been a standard technique during scientific ocean drilling expeditions to characterize sediment composition and classify sediment types, but presentation of these percent estimates to track downcore trends in sediment composition has become less frequent over the past 2 decades. We compare semi-quantitative smear slide composition estimates...
