Potential Tool Use by Wolves (
Article in Ecology and evolution, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The cognitive abilities of canids are increasingly recognized, though insights from noncaptive populations are comparatively rare. Recently, recurring damage to crab traps used by Haíɫzaqv Nation Guardians to control a European Green Crab invasion was investigated with remote cameras. A wolf was recorded emerging from the water carrying a crab trap buoy, then sequentially pulling the attached line up the beach until an initially submerged trap emerged from the water. The wolf then extracted the bait cup from within and consumed the bait. The recorded behavior, combined with similarly extracted and damaged traps nearby, suggests a sophisticated understanding of the trap and sophisticated cognition more broadly. This observation raises questions about the context and origins of the behavior and prompts consideration of our relationship with this cognitively complex species.
