Abstract

Seagrass restoration have been significantly increased worldwide and the use of seedlings have been encouraged. To successfully use seedlings in restoration, understanding the factors that affect their growth has become pivotal. This study aimed at evaluating the development of the Mediterranean seagrass Posidonia oceanica seedlings in different thermal environments by cross-transplantation between the eastern and western coast of Sardinia (Italy), and in several P. oceanica canopy densities. The thermal conditions of receiving and donor sites did not affect the development of P. oceanica seedlings, since seedlings from the same origin developed consistently in both sites, highlighting a good acclimation. Furthermore, seedlings germinated in dead matte or low canopy density generally showed a higher development, providing good insights for future restoration actions.

全球海草恢复工作大幅增加，并鼓励使用幼苗。要成功地利用幼苗进行修复，了解影响其生长的因素至关重要。本研究旨在通过撒丁岛（意大利）东西海岸之间的交叉移植，评估地中海海草 Posidonia oceanica 幼苗在不同热环境下的生长情况，以及 Posidonia oceanica 的几种冠层密度。接收地和供体地的热环境条件并不影响大洋刺幼苗的生长，因为来自同一原产地的幼苗在两个地点的生长发育一致，这突出表明了良好的适应性。此外，在死垫层或低冠层密度下发芽的幼苗一般发育较快，这为今后的恢复行动提供了很好的启示。

期刊介绍： Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes. Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following: – The extent, persistence, and consequences of change and the recovery from such change in natural marine systems – The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems – The biogeochemistry of naturally occurring and anthropogenic substances – Models that describe and predict the above processes – Monitoring studies, to the extent that their results provide new information on functional processes – Methodological papers describing improved quantitative techniques for the marine sciences.
