Multidimensional crisis in the conservation of Amu Darya false shovelnose sturgeons.
Article in npj biodiversity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A robust reassessment of extinction risk is crucial for developing evidence-based conservation strategies and preventing irreversible biodiversity loss. Sturgeons are among the most threatened freshwater fishes worldwide, yet extinction risk evaluations for the critically endangered Amu Darya false shovelnose sturgeons (Pseudoscaphirhynchus kaufmanni and P. hermanni) still largely depend on legacy information that does not reflect recent human disturbances. To re-evaluate the extinction risk of these sturgeons, we combined updated occurrence records, traditional morphometric data, mitochondrial genetic markers, and ethnobiological surveys from field expeditions, market inspections, and community interviews conducted during 2019-2024. Our results showed dramatic contraction in distribution range and an almost complete loss of population structure. The long-snouted form of P. hermanni is likely already extinct, and the short-snouted form now persists only in fragmented habitats in the middle and lower Amu Darya. Morphological comparisons revealed a marked decrease in body length and weight, indicating size-selective removal linked to illegal poaching. Genetic analyses also revealed declining diversity and signals of demographic bottlenecks, consistent with severely reduced adaptive potential. Taken together, our results indicate an urgent need for coordinated transboundary conservation to avert the imminent extinction of the two critically endangered species.
