Capelin are a major component of cod diet in many ecosystems of the North Atlantic. In
the Bering Sea, however, the percentage of capelin found in Pacific cod stomachs is negligible. We
hypothesize that the landscape (or ‘seascape’) features of hydrography and bathymetry of the Bering
Sea impose a constraint...
The Manual on Uniform Traffic Control Devices (MUTCD) specifies minimum retroreflectivity
requirements that include an obligation for agencies to develop a strategy for maintaining
compliance. States were given a deadline of January 1, 2012 for the implementation of an
assessment or management plan, which led to an increased emphasis on...
The ability to estimate and monitor standing dead trees (snags) has been difficult due to their irregular and sparse distribution, often requiring intensive sampling methods to obtain statistically significant estimates. This study presents a new method for estimating and monitoring snags using neighborhood attribute filtered airborne discrete-return lidar data. The...
Forest management problems with even-flow and adjacency considerations are difficult to solve optimally. A heuristic search intensification process, which uses two types of decision procedures, changes to single-decision choices (1-opt moves) and changes to two-decision choices simultaneously (2-opt moves), was used in an attempt to locate feasible and efficient solutions...
The use of a reversion technique during the search process of s-metaheuristics has received little attention with respect to forest management and planning problems. Reversion involves the interruption of the sequence of events that are used to explore the solution space and the re-initiation of the search process from a...
