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

Coastal and marine ecosystems provide valuable ecosystem services functions. Unfortunately, these habitats have experienced increasing anthropogenic climate‐related pressures, leading to significant degradation loss not only in Australia but also globally. Hence, the urgency for coastal restoration has never been more pronounced. We present a synthesis of 151 projects on spanning mangrove, seagrass, tidal marsh, kelp, shellfish reef, coral ecosystems. Our findings reveal increased efforts over past 30 years, with an focus reef habitats. Across Australia, most were southeastern noticeable gap Northern Territory. Restoration strategies focused enhancing propagule availability (74%) substrate (42%), additional toward implementing top–down (7%) bottom–up (4%) controls boost natural recruitment. Projects carried out participation mostly research universities (45%), followed by state government entities philanthropy (34%), private companies (16%). Funding came primarily from governmental sources, such as (50%), commonwealth (44%), (19%). outcomes are centered monitoring growth survival resulting both single multiple actions. highlight key factors influencing recruitment across habitat types, where sedimentation species reproductive biology play critical role. While acknowledging that our results represent small fraction Australia's efforts, intent is contribute insights can support large‐scale actions global scale.

Habitat complexity plays a critical role in shaping biotic assemblages and ecosystem processes. While the impacts of large differences habitat are often well understood, we know less about how subtle structure affect key functions or properties such as biodiversity biomass.

Macroalgal forests play a crucial ecological role, providing important ecosystem services, but are also among the most vulnerable marine habitats. In Mediterranean Sea, of Cystoseira sensu lato ( s.l. ) undergoing drastic decline due to presence multiple stressors, and these species, Gongolaria barbata is one threatened. Despite various attempts restore macroalgal forests, success interventions limited by availability fertile apices promote zygotes release embryo development for subsequent replacement in situ. Here, we propose new approach based on use G. stranded beach restoration We developed protocol collection macroalgae collect their produce healthy embryos, whose recruits can be then returned at sea (through ad hoc hard substrates). show that 3 months incubation mesocosms allow reach an average length 1–2 mm with density 50–80 per tile. demonstrate survive grow vigorously both mesocosms, after being outplanted sea.

Physical disturbances typically cause ecological impacts within areas of direct contact (primary disturbances) but can also impact surrounding through other mechanisms (secondary disturbances). Secondary are often overlooked, especially in marine ecosystems where sufficiently detailed observation be difficult to obtain. For example, boat moorings create circular clearings seagrass meadows by physically scouring the seabed, visible extend beyond this into due such as increased sediment transport, edge effects, and shading from boats. Previous studies on have not distinguished between primary secondary disturbances, rarely accounted for environmental management. We used spatial modelling examine associated with a meadow threatened Posidonia australis . compared disturbance traditional ‘swing’ ‘environmentally friendly’ (EFM) designed reduce scour. Within scour zone (0-5 m moorings), we cover around swing EFM. Further (5-25 m), tested degree association that may accumulate mooring density influenced design. found design affected disturbance, P. standard ~49% lower than EFMs (p < 0.01). Mooring had cumulative negative effects meadow, influence was reduced when most were EFMs. This suggests contingent physical (e.g. fragmentation, effects) stronger general moored boats (shading). use findings simulate two broad policy scenarios designs meadows: installing only EFM, or moorings. The simulations suggest using EFM would lead 14.2% increase (~164 2 ), whereas 16% (~187 ) loss already highly disturbed meadow. Synthesis applications: demonstrate nondestructive approach assessing driving distribution range potential management could assist conserving species.

Restoration is an important activity to assist the recovery of damaged or degraded ecosystems. Accessing healthy donor material can be challenging when restoring threatened ecological communities, but careful selection may improve success and cost‐effectiveness restoration projects. We aim optimize seagrass Posidonia australis by identifying traits that best predict survival establishment. To avoid collecting from populations, a recent method focuses on using naturally detached fragments P. collected shoreline, which are stored in outdoor tanks prior planting. Here, we examine 10 morphological other variables relating collection identify predicted after replanting. Fragments with more shoots less dead tissue (necrosis) their leaves had higher 1 year were longer replanting significantly rates. These results refine for used recently developed technique beach‐cast material.

Citizen science has an active role in coastal and marine ecosystem monitoring, including seagrass beds. However, as yet the use of citizen environment is limited. Moreover, there are very few studies analyzing evaluating existing successful case studies, need for such work to fill vast information gaps arguably great. This study evaluates a monitoring conducted on Chinese island Hainan from three perspectives: public participation, scientific impacts, social-ecological/economic impacts. It also analyzes assesses civil society organizations implementation projects first time. Our results challenge dominant view two-party relationship between academic researchers volunteers. The evaluation shows that impact project was limited terms social/ecological dimensions. Yet, indicate both, society, benefit taking part initiatives, it provides bridge promote collaboration institutions organizations. Finally, drawing upon lessons learned this we outline general critical features support conservation practice policy.
