Seed dispersal as a backup system to resprouting and seeding during post-fire regeneration.
Article in Annals of botany, 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
BACKGROUND AND
aimsPlant populations can recover from wildfires through resprouting (resprouters), recruiting from in situ surviving seed banks (seeders) or recolonization via seed dispersal. However, it is unclear how complementary these mechanisms can be, especially whether and how specific seed dispersal syndromes are associated with resprouter or seeder potential. In particular, it is unknown whether the occurrence of traits that facilitate seed dispersal and post-fire recolonization are disproportionately frequent among plants that lack other fire-coping strategies (i.e. colonizers).
methodsHere, we compiled information on the presence of post-fire regeneration mechanisms - resprouting potential, seeding capacity and presence of traits that facilitate seed dispersal - for 705 species from the European Mediterranean Basin. Three-way contingency tables were built and analysed using log-linear models to assess associations between the three mechanisms. KEY
resultsWe found a negative association between resprouting and seeding capacity, and observed that these mechanisms were independent of having any traits related to seed dispersal. However, traits facilitating endozoochory (fleshy fruits) were more common among resprouters than expected by chance.
conclusionsOur results show that traits enhancing seed dispersal are widespread among post-fire resprouters and seeding species in the Mediterranean Basin flora. We conclude that seed dispersal traits are mostly an independent backup system assisting the recovery of burned sites rather than an alternative to resprouting or post-fire seeding.
