Benthic biodiversity in Collins Bay (King George Island), Antarctica: evidence for small-scale community structuring.
Article in Scientific reports, 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
The Antarctic Peninsula's coastal benthic ecosystems are shaped by highly dynamic environmental drivers, hence high-resolution biodiversity studies across depth gradients are key for improve our understanding current impacts of drivers on benthic communities and future projections. Benthic megafauna and seaweeds were surveyed in Collins Bay, King George Island, using ROV video transects (10-80 m depth) and analysed for diversity and community composition in relation to environmental factors. Soft substrates dominated the area (82.44% of frames), and 157 taxa from 15 phyla were recorded, with Asteroidea occurring in 62.14% of sampled depths and Odontaster validus being the most frequently observed species. Benthic community composition differed significantly with depth, distance from the glacier, and substrate (PERMANOVA; depth: F = 16.10, R² = 11.91%, p < 0.001; distance: F = 20.38, R² = 5.03%, p < 0.05; substrate: F = 7.20, R² = 2.66%, p < 0.001), with depth explaining the largest proportion of variation. Species richness showed distance-dependent depth responses: no significant depth-related changes occurred close to the glacier, richness peaked at intermediate depths (50-60 m) at intermediate distances (negative binomial GLMM, p < 0.001), and increased strongly with depth at sites furthest from the glacier (p < 0.001). Functional composition also varied along these gradients. Sessile filter feeders dominated deeper glacial-proximal habitats, while mobile taxa increased in relative abundance with distance from the glacier, although larval dispersal strategies remained invariant across depths and distances. Macroalgal assemblages were primarily structured by depth, with species richness declining significantly below 40-50 m across all distance categories. Overall, our findings demonstrate that glacial retreat-related processes modulate how bathymetry structures benthic biodiversity, generating strong small-scale heterogeneity within a single fjord. This study provides a fine-scale baseline for detecting future changes in Antarctic benthic ecosystems under ongoing climate-driven glacial change.
