It would be valuable economically to know what are the biological triggers for formation of mature wood (currently of high value) and (or) what maintains production of juvenile wood (currently of low value), to develop silvicultural regimes that control the relative production of the two types of wood. Foresters commonly...
Stem sinuosity is thought to negatively impact wood quality, but no studies have characterized its vertical and radial effects on wood properties. Here we study wood quality along the entire stem in 25-year-old plantation grown Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) trees (32 trees total) that had been scored...
Better fisheries management is often given as one justification for research on improving forecasts of fish survival. However, the value gained from expected improvements in forecast skill in terms of achieving management goals is rarely quantified as part of research objectives. Using Monte Carlo simulations of population dynamics, we assessed...
Comme dans la plupart des pêcheries, certaines questions relatives à l'allocation des moyens d'exploitation (moyens compris au sens large, englobant l'accès à la ressource biologique, les moyens financiers, les structures, etc.) se posent aux pêcheries démersales Mauritaniennes: ici, les problèmes d'allocation s'expriment, en particulier entre armements industriels et artisanaux d'une...
