Unraveling the colonization process of microeukaryotic communities on artificial micro-ecological islands.
Article in Environmental microbiome, 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
backgroundMicro-ecological islands provide unique habitats for microbes and play a crucial role in the functioning of aquatic ecosystems. Microbes settle on these micro-ecological islands, forming distinct microbial communities. Previous studies have provided some understanding of the colonization processes and regulatory mechanisms of protozoa in microbial communities. However, these islands are also subject to colonization by a variety of microbes beyond protozoa, and comprehensive cross-kingdom studies and their potential mechanisms remain largely unexplored.
resultsUsing polyurethane foam units (PFU) to simulate micro-ecological islands, we studied the colonization dynamics of microbes in two distinct aquatic ecosystems, the Yangtze River and East Lake. Over 10-day colonization survey was conducted, we applied eDNA-PFU technology combined with metagenomic sequencing to comprehensively identify species present in the microbial communities, including bacteria, fungi, flagellates, protozoa, and metazoa. We found that microeukaryotes, rather than prokaryotes, were the primary colonizers in these two aquatic ecosystems. Our study reveals a colonization process of microeukaryotes in PFUs, profoundly influenced by their motility modes. Additionally, we propose a hypothetical food web framework within micro-ecological islands that maintains community stability, representing the most fundamental biological interactions.
conclusionsOverall, this study enriches our understanding of micro-ecological islands and provides deeper insights into the colonization processes and regulatory mechanisms of microbial communities. It highlights the practical significance of micro-ecological islands in biological resource management, environmental protection, and biodiversity conservation.
