Evidence That Metapopulation Dynamics Maintain a Species' Range Limit.
Article in Ecology letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 metapopulation hypothesis for range limits proposes that geographic variation in a species' extinction from and/or colonisation of habitat can generate an abrupt range limit. We tested whether this contributes to the northern range limit of coastal dune plant Camissoniopsis cheiranthifolia by quantifying suitable habitat area and the rates of extinction and colonisation across 3485 plots throughout the northern half of the species' range. Colonisation of previously unoccupied plots increased with suitable habitat area and abundance in nearby plots and consequently declined towards the range limit. Extinction was more frequent from plots with less habitat and lower initial abundance but did not increase significantly towards the limit. Incorporating spatial variation in estimated rates of colonisation and extinction in a metapopulation model predicted a decline in plot occupancy towards the limit that closely matched the observed decline in occupancy. Thus, variation in metapopulation dynamics may contribute to this species' range limit.
