Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary.
Article in Journal of fish biology, 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
Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary-associated species in Australia, we cannot reliably assess the functional importance of these areas or identify relevant drivers of resource partitioning in estuarine food webs. Here, we compared the diets and trophic niches of two sympatric dasyatid species, the Australian whipray Himantura australis and brown whipray Maculabatis toshi, in a tropical estuary in North Queensland. Stomach contents were collected from juvenile specimens in 2022-2025 using gastric lavage, muscle tissue samples were analysed for stable isotopes (δ
