Automated eDNA sampling for marine monitoring and biosecurity: optimising temporal resolution, remote deployments, and community engagement.
Article in PeerJ, 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
Environmental DNA (eDNA) offers unprecedented potential for monitoring high-risk coastal environments impacted by anthropogenic activities and is increasingly used for marine biosecurity applications. Yet, optimal temporal-spatial sampling strategies remain unresolved for dynamic coastal settings. Recent advances in automated eDNA sampling have allowed practitioners to improve temporal resolution, enabling simplified sampling methods and more adaptive sampling strategies. In this study, we evaluated whether higher temporal resolution improves biodiversity assessment and marine non-indigenous species (NIS) detection in a marina in Ōpua (Te Pēwhairangi (Bay of Islands), Aotearoa-New Zealand) using the recently introduced Smith-Root automated eDNA sampler. For this purpose, daily samples were collected over four weeks between 12:00-18:00 to assess eukaryotic and metazoan biodiversity using metabarcoding of the small ribosomal subunit RNA (18S rRNA) and mitochondrial
