The visual stimuli attributes instrumental for collective-motion-related decision-making in locusts.
Article in PNAS nexus, 2024. 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
Visual interactions play an instrumental role in collective-motion-related decision-making. However, our understanding of the various tentative mechanisms that can serve the visual-based decision-making is limited. We investigated the role that different attributes of the visual stimuli play in the collective-motion-related motor response of locust nymphs. We monitored and analyzed the behavioral responses of individual locusts tethered in a natural-like walking posture over an airflow-suspended trackball to carefully selected stimuli comprising various black rectangular shapes. The experimental findings together with a prediction model relating the level of behavioral response to the visual stimuli attributes indicate a major role of the number of objects in the visual field, and a further important effect of the object's vertical moving edges. While the object's horizontal edges can be utilized in the estimation of conspecifics' heading, the overall area or visual angle subtended by the stimuli do not seem to play any role in inducing the response. Our results offer important novel insights regarding the fundamental visual-based mechanisms underlying animal collective motion and can be useful also in swarm robotics.
