Global pelagic dispersal traits datasets for early-life stages of marine fishes.
Article in Scientific data, 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
Although larval stages ensure most connectivity between demersal fish populations, dispersal traits are increasingly less measured, despite the importance of correctly parametrizing biophysical models for spatial conservation planning. Moreover, existing data are scattered across a vast multidisciplinary literature. To address this mismatch between need and availability, we compiled data from 3,201 references into multiple datasets covering 35 key pelagic dispersal traits across fish early-life stages. We specifically compiled data on swimming speed, vertical position, and delayed settlement in demersal fishes (rafting or pelagic juveniles), as these traits exert a major yet understudied influence on dispersal scale. We systematically reported all descriptive statistics, enabling robust fitting of probability density functions to introduce particle-level variability in Lagrangian models. Overall, datasets comprise 32,988 species-level (1,709 for higher-taxon-level) records for 6,841 marine fish species worldwide, including 1,155 unpublished records (other teams), and 313 records newly collected during two fieldworks (Maldives & Guadeloupe). We also digitized 12,322 individual-level age-at-length/weight records from rearing experiments, enabling temperature-dependent growth model fitting to forecast global warming impacts on dispersal.
