“…Here we document for the first time the use of the BOSSline method (Bags of Seagrass Seeds Line) for deploying seeds of the seagrass Zostera marina. Seedling establishment rates (the proportion of seeds generating a surviving seedling) was low (3.5%) but typical of an r-strategist species and comparable to many rates recorded in other studies and sites (Marion and Orth, 2010;Govers et al, 2016;Sousa et al, 2017). The reasons for such low rates could be local environmental conditions, health of the seeds, or even disease contamination (Govers et al, 2016).…”

“…Additionally, recent successful trials of Z. marina restoration in Sweden have also included the use of seeds (Infantes et al, 2016a,b). Projects planting seeds have used a range of methods such as spreading by hand at the water surface, the use of seed buoys (Pickerell et al, 2005), and more recently planting of seeds in coconut matting (Sousa et al, 2017). In many parts of the UK the effectiveness of any technique that involves the loose spreading of seed (e.g., seed buoys) is likely to be compromised by the very large tidal ranges and resultant fast tidal currents that can rapidly move seeds away from their intended location.…”

Sowing the Seeds of Seagrass Recovery Using Hessian Bags

Seagrass meadows are an important wetland habitat that have been degraded globally but have an important carbon storage role. In order to expand the restoration of these productive and biodiverse habitats methods are required that can be used for large scale habitat creation across a range of environmental conditions. The spreading of seagrass seeds has been proven to be a successful method for restoring seagrass around the world, however in places where tidal range is large such methods become limited by resultant water movements. Here we describe and test a method for deploying seagrass seeds of the species Zostera marina over large scales using a new, simple method "Bags of Seagrass Seeds Line (BoSSLine)." This method involved planting seeds and sediment using natural fiber hessian bags deployed along strings anchored onto the seabed. When deployed in a suitable environment 94% of bags developed mature seagrass shoots, unfortunately one site subjected to a large storm event resulted in sediment burial of the bags and no seed germination. Bags were filled with 100 seeds with each leading to the development of 2.37 ± 2.41 mature shoots (206 ± 87 mm in length) 10 months after planting. The method was proven successful however the experiments illustrated the need to ensure habitat suitability prior to their use. Low seed success rate was comparable to other restoration studies, however further trials are recommended to ensure ways to improve this rate. In conclusion, this study provides evidence for an effective, simple method "Bags of Seagrass Seeds Line (BoSSLine)" for deploying seeds of the seagrass Zostera marina over large scales.

This chapter presents the co-development of the Ecosystem-Based Management (EBM) planning process in the Vouga estuary for the mitigation of unintended impacts on biodiversity resulting from the 2019/2020 management plan. This estuary, part of Ria de Aveiro coastal lagoon located on the northwest coast of Portugal (40 38 0 N, 08 45 0 W), connects the Vouga river catchment area to the Atlantic Ocean. Ria de Aveiro, part of the Natura 2000 network, is characterised by high biodiversity and a wide range of ecosystem services. However, it is also a vulnerable territory that requires a management plan in practice for environmental protection, targeting threatened species and habitats, but also to enable socioeconomic welfare. Framed by EBM principles, the stepwise planning approach aimed at identifying the governance boundaries and institutions, the policy objectives, synergies, and gaps relevant to managing biodiversity, and to promote participatory actions with local stakeholders and policy-makers to understand their objectives. These three first steps enabled us to understand the social-ecological system and to co-develop relevant EBM solutions. In the final step, the proposed

Bu çalışmada, Zostera marina L. atık biyoması ile sucul ortamdan model bir sentetik azo boyanın (basic red 46) biyosorpsiyonu ilk kez araştırılmıştır. Deneysel veriler, boya gideriminin önemli bir şekilde pH, biyosorbent miktarı, boya konsantrasyonu ve temas süresine bağlı olduğunu göstermiştir. Optimal biyosorpsiyon koşulları, pH 8, 10 mg biyosorbent dozajı, 30 mg L-1 boya konsantrasyonu ve 360 dakika temas süresi olarak belirlenmiştir. Biyosorpsiyon kinetik verileri, yalancı birinci mertebe, yalancı ikinci mertebe, Elovich ve parçacık içi difüzyon modelleri kullanılarak analiz edilmiştir. Freundlich, Langmuir ve Dubinin-Radushkevich modelleri, deneysel izoterm verilerini modellemek için kullanılmıştır. Modelleme çalışmaları sonuçları, Elovich ve Freundlich modellerinin, biyosorpsiyon kinetik ve izoterm verilerine en iyi uyumu sağladığını göstermiştir. Langmuir denge modeline bağlı olarak biyosorbentin maksimum boya biyosorpsiyon kapasitesi, 160,882 mg g-1 olarak tahmin edilmiştir. Termodinamik çalışmalar, biyosorpsiyon prosesinin doğasını ortaya koymak için yapılmıştır ve elde edilen sonuçlar, biyosorpsiyon sisteminin, spontan ve fiziksel bir doğaya sahip olduğuna işaret etmiştir (ΔG° =-8,604-5,926 kJ mol-1). Elde edilen tüm bulgular, bu doğal biyolojik atığın, su ortamından böyle kirletici ajanların uzaklaştırılması için uygun maliyetli bir biyosorbent materyali olarak etkili bir şekilde kullanılabileceğini göstermiştir.
