Abstract The recovery of the Canada goose (Branta canadensis) is one of North America's greatest conservation success stories. Today, continental abundance of temperate‐breeding Canada geese (those breeding in southern Canada and lower 48 states in the United States) greatly exceeds historical levels.

Sustained non‐lethal hazing was associated with reduced wildlife use of runway‐adjacent critical areas while overall wildlife numbers remained stable. Bayesian models of operational hazing records showed that the proportion of individuals in critical areas declined, lower hazing escalation was required over time, and pre‐ and post‐hazing response ...

ABSTRACT Fishless lakes, which may harbour higher biodiversity than lakes with fish, are becoming increasingly rare due to fish introductions. Although the impacts of fish introduction are relatively well studied in high‐elevation fishless lakes, previous studies have mainly focused on a single invertebrate community or on a particular life stage of a ...
