Yet, comparative studies, to identify species\u2019 strategies, and integration of the relative importance of photoacclimatory adjustments at different levels are still missing. The variation in photoacclimatory responses at the chloroplast and leaf level were studied along individual leaves of <jats:italic>Cymodocea nodosa, Zostera marina<\/jats:italic> and <jats:italic>Z. noltei<\/jats:italic>, including measurements of variable chlorophyll fluorescence, photosynthesis, photoprotective capacities, non-photochemical quenching and D1-protein repair, and assessments of variation in leaf anatomy and chloroplast distribution. Our results show that the slower-growing <jats:italic>C. nodosa<\/jats:italic> expressed rather limited physiological and biochemical adjustments in response to light availability, while both species of faster-growing <jats:italic>Zostera<\/jats:italic> showed high variability along the leaves. In contrast, the inverse pattern was found for leaf anatomical adjustments in response to light availability, which were more pronounced in <jats:italic>C. nodosa<\/jats:italic>. This integrative plant organizational level approach shows that seagrasses differ in their photoacclimatory strategies and that these are linked to the species\u2019 life history strategies, information that will be critical for predicting the responses of seagrasses to disturbances and to accordingly develop adequate management strategies.<\/jats:p>","DOI":"10.1038\/s41598-018-33259-4","type":"journal-article","created":{"date-parts":[[2018,9,28]],"date-time":"2018-09-28T11:01:52Z","timestamp":1538132512000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Photoacclimation strategies in northeastern Atlantic seagrasses: Integrating responses across plant organizational levels"],"prefix":"10.1038","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7161-7882","authenticated-orcid":false,"given":"Nadine","family":"Schubert","sequence":"first","affiliation":[]},{"given":"C\u00e1tia","family":"Freitas","sequence":"additional","affiliation":[]},{"given":"Andr\u00e9","family":"Silva","sequence":"additional","affiliation":[]},{"given":"Monya M.","family":"Costa","sequence":"additional","affiliation":[]},{"given":"Isabel","family":"Barrote","sequence":"additional","affiliation":[]},{"given":"Paulo A.","family":"Horta","sequence":"additional","affiliation":[]},{"given":"Ana Claudia","family":"Rodrigues","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7861-4366","authenticated-orcid":false,"given":"Rui","family":"Santos","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o","family":"Silva","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2018,10,4]]},"reference":[{"key":"33259_CR1","doi-asserted-by":"publisher","first-page":"438","DOI":"10.1046\/j.1365-3040.1997.d01-95.x","volume":"20","author":"EH Murchie","year":"1997","unstructured":"Murchie, E.
