Environmental quality affects the formation of generalist and specialist taxa in microbial communities.
Article in ISME communications, 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
Microorganisms play a central role in global biogeochemical cycles, and generalists and specialists differ significantly in environmental adaptability, ecological functions, and community stability. However, current studies on generalists and specialists have mainly focused on habitat type or resource availability, while how habitat quality affects their geographic distribution and succession processes remains unclear. This study investigates how habitat quality influences the geographical distribution and community assembly of generalists and specialists. Using the Remote Sensing Ecological Index (RSEI), we assessed soil ecological quality in the Tarim River Basin and categorized the habitats into low-quality (extreme poor), moderate-quality (moderate poor), and high-quality (relatively good) zones. We analyzed the geographical patterns of generalists/specialists and their community assembly processes as habitat quality declined. Results indicated significant differences in microbial community composition (β-diversity, Bray-Curtis distance) between generalist and specialist groups across habitats. As RSEI decreased, the relative abundance of specialist microorganisms increased, while generalist microorganisms decreased. Microbial community assembly was shaped by both stochastic and deterministic processes, with stochastic processes accounting for >75%. Deterministic processes have a greater impact on specialists than generalists. This study provides insights into how environmental changes affect microbial ecosystems and their dynamics.
