Woody species diversity and dispersal dynamics in Biyo Forest, Central Ethiopia: a conservation perspective.
Article in BMC ecology and evolution, 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
backgroundSeed dispersal shapes species composition, regeneration, and long-term resilience of dry Afromontane forests. In Ethiopia, there is limited information on how woody species disperse and recruit. Biyo Forest, a protected exclosure in central Ethiopia, offers an opportunity to study how different dispersal methods shape forest structure and inform conservation efforts. This study looked at the types of woody species present, their population structure, regeneration status, and how they are dispersed to better understand what supports forest sustainability.
methodsWoody species were surveyed along seven transects, using 28 plots measuring 20 × 20 m, with nested 2 × 2 m subplots. GPS randomization made sure the transects were placed without bias. Plants were grouped as seedlings, saplings, or mature based on their height and diameter. Importance Value Index (IVI), Shannon diversity, basal area dominance (RDO), regeneration ratios, and species dominance were computed. Dispersal syndromes were assigned using fruit and seed features and regional plant guides. Statistical analyses were performed using ANOVA, Kruskal-Wallis, correlations, regression, and PCA to explore links between dispersal types, IVI, and regeneration.
results27 woody species from 15 families were recorded, with Fabaceae dominating. Species diversity was moderate (H' = 2.84). Endozoochory was the dominant dispersal mode (48.15%), followed by anemochory (22.22%) and autochory (18.52%). Species density strongly predicted IVI (r = 0.92), and PCA revealed that endozoochorous species clustered with high ecological importance. Basal area dominance and IVI-based clustering identified four species (e.g., Ficus sycomorus, Vachellia sieberiana) with regeneration failure, while pioneers such as Dodonaea angustifolia showed strong recruitment. Overall, Biyo Forest recorded 1288.4 seedlings/ha, 836.6 saplings/ha, and 1013.4 mature individuals.
conclusionBiyo Forest is dominated by animal-dispersed species, emphasizing frugivores' role in forest dynamics. Several species face regeneration bottlenecks, indicating the need for targeted conservation, protection of keystone species, and maintenance of frugivore networks to sustain ecological resilience.
