Niche Breadth and Olfactory Context Shape Informed Passive Dispersal.
Article in Ecology letters, 2026. 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
Animals must decode environmental information to make adaptive decisions. In passive dispersers, for whom only departure timing is under control, the mechanisms of take-off remain poorly understood. Using experimental evolution, we tested how niche breadth modulates passive dispersal in phytophagous mites by exposing specialist and generalist lineages to host-derived kairomones. Dispersal was highly context-dependent. Generalists exhibited higher baseline dispersal and increased take-off when detecting familiar target cues; however, they were inhibited by complex mixtures of unfamiliar cues (low signal-to-noise ratio). Conversely, specialists primarily tracked current host quality, departing significantly more frequently from unfamiliar plants, yet showing little modulation by target cue identity. These results demonstrate that divergent host specialisation in homogeneous versus heterogeneous environments fundamentally alters the way in which organisms integrate information from current and future habitats to drive dispersal. Niche breadth dictates the baseline propensity for informed departure, while olfactory context provides the final trigger for passive take-off.
