When Two Species Meet: A Potential Beetle-Yeast Facultative Mutualism.
Article in Environmental microbiology reports, 2025. 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
Facultative mutualisms, such as some insect-yeast interactions, can be established between partners that only interact in certain stages of their life cycles. While exploring yeasts associated with Brazilian beetles, we found a particular Cyberlindnera yeast associated with Spermophthorus apuleiae. This yeast was found within the beetles' galleries, which are excavated in fruits of Libidibia ferrea, a native Brazilian tree. We isolated a total of 15 yeast and yeast-like species associated with the fruits and beetles, mostly from the orders Phaffomycetales and Serinales, and explored their role in yeast-beetle interactions. Cyberlindnera is the most recurrent yeast, found in 90% of the fruit samples infested with beetles and representing 79% of the total isolates. Results from bioassays support the interaction between Cyberlindnera and Spermophthorus apuleiae. We hypothesise that reciprocal benefits may underlie this association: beetle gallery excavation boosts the density of Cyberlindnera in fruits, while the yeast produces attractive volatiles to beetles. These volatiles are usually associated with signalling towards sugar resources that enhance dispersal, an idea that warrants further exploration. We consider the Cyberlindnera-beetle association a potential model for studying the ecology and evolution of non-obligate (facultative) mutualisms.
