If populations vary in their environmental sensitivity to marginal temperatures across a species’ geographical range, populations that respond better to future environmental extremes are likely to be critical for maintaining ecological resilience of the species. / Using seeds from two to six populations for each of nine species of Mediterranean plants, we characterized patterns of among-population variation in environmental sensitivity by quantifying genotype-by-environment interactions (G × E) for germination success at temperature extremes, and under two light regimes representing conditions below and above the soil surface. / For eight of nine species tested at hot and cold marginal temperatures, we observed substantial among-population variation in environmental sensitivity for germination success, and this often depended on the light treatment. Importantly, different populations often performed best at different environmental extremes. / Our results demonstrate that ongoing changes in temperature regime will affect the phenology, fitness, and demography of different populations within the same species differently. We show that quantifying patterns of G × E for multiple populations, and understanding how such patterns arise, can test mechanisms that promote ecological resilience. date: 2020-06 date_type: published publisher: WILEY official_url: https://doi.org/10.1111/nph.16453 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1790636 doi: 10.1111/nph.16453 lyricists_name: Bridle, Jonathan lyricists_id: JBRID88 actors_name: Bridle, Jonathan actors_id: JBRID88 actors_role: owner full_text_status: public publication: New Phytologist volume: 226 number: 5 pagerange: 1312-1324 pages: 13 citation: Walter, GM; Catara, S; Bridle, JR; Cristaudo, A; (2020) Population variation in early development can determine ecological resilience in response to environmental change.
