Abstract

Seagrasses provide key ecological services in coastal marine and estuarine environments. Human activities and environmental changes affect seagrasses compromising their structure and functioning. In this context, seagrass restoration has become a worldwide priority to halt and reverse degradation and to recover ecosystem functionality and associated services. Here, we investigate the sexual reproduction of Posidonia oceanica by describing the flowering and fruiting process. Furthermore, we compare the structural (survival and shoot density) and functional (daily leaf production, DLP) descriptors of seedlings with those derived from a P. oceanica transplantation performed through cuttings to assess their feasibility as an integrative source of vegetal material for restoration purposes. Despite many initial flowers and fruits, a small number of mature fruits are produced, confirming the low reproductive success of the phanerogam. A comparison of structural and functional features showed that seedlings and cuttings showed similar survival and shoot density rates after more than 2 years. In addition, DLP showed that seedlings increased in leaf length over the study period, reaching a similar value registered by cuttings. The study demonstrates the effectiveness of using seedlings in restoration efforts. It also emphasizes the importance of exploring P. oceanica reproductive ecology to better understand temporal and spatial variations in flowering, as well as fruiting success, at local and basin scales.

Posidonia oceanica (L.) Delile, 1813幼苗作为恢复受损草地的潜在综合工具

海草为沿海海洋和河口环境提供重要的生态服务。人类活动和环境变化会影响海草，损害其结构和功能。在这种情况下，恢复海草已成为全世界的当务之急，以阻止和扭转退化，恢复生态系统的功能和相关服务。在此，我们通过描述海草的开花和结果过程来研究海草的有性繁殖。此外，我们还比较了幼苗的结构（存活率和嫩枝密度）和功能（日产叶量，DLP）描述指标，以及通过扦插移植获得的描述指标，以评估其作为用于恢复目的的植物材料综合来源的可行性。尽管最初的花和果实很多，但结出的成熟果实数量很少，这证实了该植物的繁殖成功率很低。对结构和功能特征的比较表明，幼苗和插条在两年多后的存活率和枝条密度相似。此外，DLP 显示，在研究期间，幼苗的叶长有所增加，达到了与扦插苗相似的数值。这项研究证明了在恢复工作中使用幼苗的有效性。该研究还强调了探索大洋洲杉繁殖生态学的重要性，以便更好地了解当地和流域范围内开花和结果成功率的时空变化。

期刊介绍： Restoration Ecology fosters the exchange of ideas among the many disciplines involved with ecological restoration. Addressing global concerns and communicating them to the international research community and restoration practitioners, the journal is at the forefront of a vital new direction in science, ecology, and policy. Original papers describe experimental, observational, and theoretical studies on terrestrial, marine, and freshwater systems, and are considered without taxonomic bias. Contributions span the natural sciences, including ecological and biological aspects, as well as the restoration of soil, air and water when set in an ecological context; and the social sciences, including cultural, philosophical, political, educational, economic and historical aspects. Edited by a distinguished panel, the journal continues to be a major conduit for researchers to publish their findings in the fight to not only halt ecological damage, but also to ultimately reverse it.
