Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism.

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
Most studies of the chemical ecology of plant-pollinator interactions emphasize the role of pollinator-mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals. To investigate whether phylogenetic history constrains plant chemical communication, we used the obligate fig-fig wasp mutualism. We collected floral scents from receptive figs of 32 Ficus species, representing diverse lineages across tropical and subtropical regions, using dynamic headspace extraction. Chemical compositions were analyzed via gas chromatography-mass spectrometry and evaluated for the phylogenetic signal using multivariate analyses. Our results revealed a strong phylogenetic signal in the volatile organic compounds (VOCs) emitted by receptive figs. Conversely, using the same analysis, we found no relationship between the scent profile and the pollinator phylogeny. Our findings demonstrate, across diverse Ficus lineages, that phylogenetic constraints play a significant role in the diversification of VOC signals emitted by receptive flowers, suggesting constraints in the biosynthetic pathways of volatile compounds.
