Non-destructive DNA extraction for recovering mitochondrial genomes from museum grasshopper specimens.
Article in PloS one, 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
Museum collections of grasshoppers contain valuable genetic data for evolutionary, ecological, and systematic studies, but destructive sampling and complex molecular techniques often limit their use. This study presents a simple, non-destructive DNA extraction protocol designed for dried grasshopper specimens, effectively balancing DNA yield with morphological preservation. We tested this method on specimens aged 6-43 years, exploring various lysis conditions to optimize DNA recovery while maintaining specimen integrity. The protocol successfully extracted sufficient DNA to assemble mitochondrial genomes for most samples using cost-effective low-coverage shotgun sequencing. DNA from younger specimens produced the best results, while older samples (over 40 years) showed some challenges, though post-collection damage did not significantly affect mitochondrial sequence assembly. Additionally, we provide practical bioinformatics recommendations for processing short reads from dried specimens. Requiring minimal molecular expertise and relying on standard sequencing services, this accessible method is well-suited for widespread adoption. By unlocking genetic insights from museum collections, it offers new opportunities to deepen our understanding of grasshopper evolution and ecological dynamics.
