Among- and within-population variation in germination response shapes ecological resilience in the Mediterranean cliff species Brassica incana.

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
aimsUnderstanding how plant species respond to extreme conditions is crucial for predicting their ecological resilience under climate change. Here, we aimed to forecast the ecological resilience of the Mediterranean cliff species Brassica incana (Brassicaceae) by estimating population variation in germination response under novel extreme environmental conditions.
methodsWe investigated the thermal germination responses in 14 populations of B. incana by exposing seeds to temperatures within and outside conditions experienced in their local environment. Then, we quantified among- and within-population variation in germination response to extreme temperatures, estimated genotype-by-environment interactions (G × E) and tested if population performance at extreme temperatures is explained by local climate. KEY
resultsWe found significant among-population differences in germination response, a different level of within-population variability and different mechanisms underlying G × E patterns. Also, populations experiencing higher temperatures in their local environment showed a better performance at both cold and hot extremes while populations experiencing lower temperatures showed a limited ability to germinate under extreme conditions.
conclusionsOur results suggest that populations experiencing higher temperatures in their local environment have a greater potential to face future thermal extreme conditions and their role is thus crucial to promote species ecological resilience.
