2024, Report
Our understanding of the mechanisms controlling eustatic sea level and global climate changes has been hampered by a lack of appropriate fossil coral records over the last 500 ky, particularly into and out of the glacial periods. This problem was addressed by International Ocean Discovery Program Expedition 389 by drilling...
Defining sediment handling practices to limit negative impacts to larval lampreys
Theresa L. Liedtke, Joe Skalicky, Lisa K. Weiland, Julie Harris, Ann E. Gray, Ralph Lampman, Joy Wade
2024, Report
Sediment manipulation activities such as dredging and restoration efforts (e.g., culvert install/repair) may disturb habitats where larval lampreys live burrowed in stream sediments. Sediment added on top of larval lamprey burrowing areas results in ‘overburden’, which poses risks of mortality from respiratory distress, reduced movement, and crushing injuries or may...

Evaluating behavioral responses of spawning-phase Walleyes to odors of rivers and other Walleyes
Tyler Buchinger, Troy Zorn, Nicholas S. Johnson, Weiming Li
2024, Fisheries Report 42
Many fish species show a remarkable ability to home to streams for spawning and fishery managers have applied that knowledge to restore or rehabilitate populations of some species. Walleye Sander vitreus show strong homing tendencies and the ability to select their natal river from other streams. The role of olfactory...

Reuben B. Smit, Damon H. Goodman, Josh Boyce, Nicholas A. Som
2024, River Research and Applications (40) 1912-1924
Estimating the impacts of water allocation decisions on fish populations and habitat availability is an important part of environmental flow assessments, especially in locations where water resources are limited. Two-dimensional hydrodynamic models (2DHMs) are commonly coupled with biological models to estimate fish habitat quality, area, and capacity across a range...

Effects of trap funnel and finger design on Sea Lamprey entrance and retention
Peter J. Hrodey, Gale Bravener, Scott M. Miehls
2024, Water (16)
Traps are used to catch adult sea lampreys during their upstream migration to estimate their abundance in streams and, in turn, provide a measure of the Sea Lamprey Control Program’s effectiveness. During 2015 and 2016, we experimentally compared two components of sea lamprey trap design: trap entrance funnel type and...

Using stable oxygen isotope dual-inlet isotope-ratio mass spectrometry to elucidate uranium transport and mixed 230Th/U calcite formation ages at the seminal Devils Hole, Nevada, natural laboratory
Tyler B. Coplen, Robert R. Seal, II, Lauren T Reid, James A Jordan, Adam C. Mumford
2024, Rapid Communications in Mass Spectrometry (39)
RationaleVein calcite in Devils Hole has been precipitating continuously in oxygen-isotope equilibrium at a constant temperature for over 500 000 years, providing an unmatched δ18O paleoclimate time series. A substantial issue is that coeval calcite (based on matching δ18O values) has uranium-series ages differing by 12 000 years.MethodsAn unparalleled high-accuracy δ18O chronology series from continuously submerged calcite...
