Variation in self-compatibility among genotypes and across ontogeny in a self-fertilizing vertebrate,
Article in Proceedings. Biological sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Mixed-mating strategies can maximize the benefits and limit the costs of both self-fertilization and outcrossing. In addition to ecological conditions and population dynamics, the economics of mixed mating are determined by individual self-compatibility, i.e. the proportion of self-fertilization events that result in viable offspring. In gynodioecious (hermaphrodites and females) and androdioecious (hermaphrodites and males) species, self-compatibility of hermaphrodites dictates the reproductive potential of the other sex and can exert strong selection on maintenance of the non-hermaphroditic sex. Mangrove rivulus fish populations are androdioecious, and males result from hermaphrodites changing sex. Hermaphrodites overwhelmingly reproduce through internal self-fertilization, but occasionally oviposit unfertilized eggs, which males can fertilize externally. We tested the hypotheses that self-compatibility and fecundity would vary with age and as a function of genotypic variation in propensities for sex change. We reveal that fecundity and self-compatibility vary within individuals across ontogeny and among genotypes with different propensities to change sex. Hermaphrodites from genotypes that frequently change sex were significantly less fecund and self-compatible than hermaphrodites from genotypes that rarely change sex. These differences in self-compatibility and fecundity have the potential to drive mating strategy evolution in mangrove rivulus, specifically the fitness of males and associated spatiotemporal variation in sex ratios within and among populations.
