In eastern North America, two main insecticide-based strategies are used to manage spruce budworm ( Choristoneura fumiferana ) outbreaks. The traditional ‘Foliage Protection Strategy’ (FPS) focuses on temporarily reducing defoliation and tree mortality in high-value stands, allowing outbreaks to progress naturally in surrounding areas. The ‘Early Intervention Strategy’ (EIS) is an adaptive, area-wide management approach that t...

Accurate and precise age determination is essential for estimating key life-history parameters in fishes. Recent studies suggest that some fisheries management metrics, such as mortality, may be robust to biased age estimates. Thus, it can be more important to identify the most precise structure for age assignment. However, precision can vary geographically, highlighting the need for location-specific evaluations. Smallmouth b...

Pesticides have been used in Canada since 1945 as part of large‐scale aerial spray applications to control insect pests on forested lands. Some of the pesticides used historically were efficacious, nonselective, persistent, and have led to serious impacts on the environment. A well known, and extensively documented example is the large‐scale aerial spray programs in New Brunswick, Canada. From 1952 to 1993, 97% of the 6.2 mill...
