Nore Praet, Maarten Van Daele, Tim Collart, J. Moernaut, Elke Vandekerkhove, P. Kempf, Peter J. Haeussler, M. De Batist
2020, Sedimentology (67) 2332-2359
Turbidites embedded in lacustrine sediment sequences are commonly used to reconstruct regional flood or earthquake histories. A critical step for this method to be successful is that turbidites and their trigger mechanisms are determined unambiguously. The latter is particularly challenging for prehistoric proglacial lake records in high-seismicity settings where both...

Christopher J. Sullivan, Michael J. Weber, Clay Pierce, Carlos A. Camacho
2020, Journal of Fish and Wildlife Management (11) 99-111
Grass Carp Ctenopharyngodon idella have been intentionally stocked for aquatic vegetation control across the Midwestern United States for several decades. During the 1970s, escapement of Grass Carp into the Missouri River facilitated their naturalization into much of the Mississippi River basin, including the Upper Mississippi River. Lock...
Patterns of denitrification potential in tidal freshwater forested wetlands
Alicia R. Korol, Gregory E. Noe
2020, Article
Limited evidence for spatial patterns of denitrification in tidal freshwater forested wetlands (TFFWs), seemingly due to high spatial variability in the process, is surprising considering the various spatial gradients of its biogeochemical and hydrogeomorphic controls in these ecosystems. Because certain physical environmental gradients may be useful for the prediction of...

Early goose arrival increases soil nitrogen availability more than an advancing spring in coastal western Alaska
Ryan T. Choi, Karen H. Beard, Katherine Kelsey, Joshua Leffler, Joel A. Schmutz, Jeffrey Welker
2020, Ecosystems (23) 1309-1324
An understudied aspect of climate change-induced phenological mismatch is its effect on ecosystem functioning, such as nitrogen (N) cycling. Migratory herbivore arrival time may alter N inputs and plant–herbivore feedbacks, whereas earlier springs are predicted to increase N cycling rates through warmer temperatures. However, the relative importance of these shifts...
