Estimating Cohort Survival through Tributaries for Salmonid Populations with Variable Ages at Migration

Autor: Charles G. Snow, Rebecca A. Buchanan, John R. Skalski, Andrew R. Murdoch, Gregory Mackey

Publikováno v: North American Journal of Fisheries Management. 35:958-973

Survival of juvenile anadromous Pacific salmonids from their earliest age of seaward movement (“out-migration”) through the tributaries that connect their rearing grounds to larger-order rivers (“cohort survival”) is an important yet often un

Ecological risk assessment of multiple hatchery programs in the upper Columbia watershed using Delphi and modeling approaches

Autor: Todd N. Pearsons, Joseph L. MIller, Andrew R. Murdoch, Tracy W. Hillman, Gregory Mackey, Keely G. Murdoch, Matt R. Cooper

Publikováno v: Environmental Biology of Fishes. 94:87-100

Ecological risks of Pacific salmon (spring, summer, and fall run Chinook, coho, and sockeye salmon) and steelhead trout hatchery programs operated between 2013 and 2023 in the Upper Columbia Watershed will be assessed using Delphi and modeling approa

A Functional Relationship Between Watershed Size and Atlantic Salmon Parr Density

Autor: Gregory Mackey, John A. Sweka

Publikováno v: Journal of Fish and Wildlife Management. 1:3-10

Atlantic salmon Salmon salar are at critically low levels in Maine rivers and maintaining current populations depends heavily on the stocking of hatchery-produced fry. Fry survival varies greatly not only among rivers but also within rivers. Better u

The geomorphic function and characteristics of large woody debris in low gradient rivers, coastal Maine, USA

Autor: M. Laser, G. B. Fisher, Gregory Mackey, Francis J. Magilligan, Keith H. Nislow, Jed Wright

Publikováno v: Geomorphology. 97:467-482

The role, function, and importance of large woody debris (LWD) in rivers depend strongly on environmental context and land use history. The coastal watersheds of central and northern Maine, northeastern U.S., are characterized by low gradients, moder

Comparisons of Run Timing, Spatial Distribution, and Length of Wild and Newly Established Hatchery Populations of Steelhead in Forks Creek, Washington

Autor: Gregory Mackey, Thomas P. Quinn, Jennifer E. McLean

Publikováno v: North American Journal of Fisheries Management. 21:717-724

In Washington State, the approach to management of wild and hatchery steelhead trout Oncorhynchus mykiss has been to separate the timing of return and spawning by the two groups through selective breeding for early timing in hatchery fish. However, o

First Documented Case of Anadromy in a Population of Introduced Rainbow Trout in Patagonia, Argentina

Autor: Michael T. Kinnison, Robert M. Walker, Gregory Mackey, Miguel Pascual, Carla Riva Rossi, Paul Bentzen

Publikováno v: Transactions of the American Fisheries Society. 130:53-67

The examination of population-specific adaptations of introduced salmonids to the wide range of environments found in Patagonia (southern South America) can help unveil some of the genetic and environmental contributions to life history variation. Th

LDRD final report : massive multithreading applied to national infrastructure and informatics

Autor: Brad Mancke, Jonathan W. Berry, Cynthia A. Phillips, Bruce A. Henderson, Kyle B. Wheeler, Ali Pinar, Brian W. Barrett, Vitus J. Leung, Richard C. Murphy, Gregory Mackey, Randall A. LaViolette

Large relational datasets such as national-scale social networks and power grids present different computational challenges than do physical simulations. Sandia's distributed-memory supercomputers are well suited for solving problems concerning the l
