The river corridor’s evolving connectivity of lotic and lentic waters
Judson Harvey, Noah Schmadel
2021, Frontiers in Water (2)
River corridors supply a substantial proportion of the fresh water for societal and ecological needs. Individual functions of flowing (lotic) streams and rivers and ponded (lentic) waterbodies such as lakes and reservoirs are well-studied, but their collective functions are not as well understood. Here we bring together nationally consistent river...

Self-organization is a process of establishing and reinforcing local structures through feedbacks between internal population dynamics and external factors. In reef-building systems, substrate is collectively engineered by individuals that also occupy it and compete for space. Reefs are constrained spatially by the physical environment, and by mortality, which reduces production...

Michael B. Duncan, Robert G. Bramblett, Alexander V. Zale
2021, Canadian Journal of Zoology (99) 45-56
Reduced population connectivity has been implicated as a cause of decreased distributions and abundances of many Great Plains fishes. However, scant empirical evidence quantifying movement and relating the contribution of spatial linkages to population abundances and resilience exists. We used otolith microchemistry analysis to characterize the movements of western silvery...

2021, Book chapter, Renewing our rivers: Stream corridor restoration in dryland regions
Often overlooked and underfunded, ecological monitoring is an essential component of stream-restoration work. It helps practitioners to identify successful restoration practices, detect ineffective ones, and adjust their adaptive-management activities to improve efficacy (Bernhardt and Palmer 2011). Monitoring, along with research and modeling, are the three legs of the scientific stool...

Kristen Hart, Jacquelyn C. Guzy, Brian J. Smith
2021, Movement Ecology (9)
BackgroundSatellite tags have revolutionized our understanding of marine animal movements. However, tags may stop transmitting for many reasons and little research has rigorously examined tag failure. Using a long-term, large-scale, multi-species dataset, we evaluated factors influencing tracking duration of satellite tags to inform study design for future tracking studies.MethodsWe leveraged...

Kevin R. Milner, Bruce E. Shaw, Christine A. Goulet, Keith B. Richards-Dinger, Scott Callaghan, Thomas H. Jordan, James H. Dieterich, Edward H. Field
2021, Bulletin of the Seismological Society of America (111) 898-915
We present a nonergodic framework for probabilistic seismic‐hazard analysis (PSHA) that is constructed entirely of deterministic, physical models. The use of deterministic ground‐motion simulations in PSHA calculations is not new (e.g., CyberShake), but prior studies relied on kinematic rupture generators to extend empirical earthquake rupture...
Using heat to trace vertical water fluxes in sediment experiencing concurrent tidal pumping and groundwater discharge
N LeRoux, B. Kurylyk, Martin A. Briggs, D. Irvine, J Tamborski, V. F. Bense
2021, Water Resources Research (57)
Heat has been widely applied to trace groundwater‐surface water exchanges in inland environments, but it is infrequently applied in coastal sediment where head oscillations induce periodicity in water flux magnitude/direction and heat advection. This complicates interpretation of temperatures to estimate water fluxes. We investigate the convolution of...
