Global seagrass habitats are threatened by multiple anthropogenic factors. Effective management of seagrasses requires information on the relative impacts threats; however, this is rarely available. Our goal was to use knowledge experts assess activities in six global bioregions. The that threaten were identified at an international workshop and followed with a web-based survey collect vulnerability information. There consensus urban/industrial runoff, urban/port infrastructure development,...
Seagrasses are important marine ecosystems situated throughout the world's coastlines. They facing declines around world due to global and local threats such as rising ocean temperatures, coastal development pollution from sewage outfalls agriculture. Efforts have been made reduce seagrass loss through reducing regional stressors, active restoration. Seagrass restoration is rapidly maturing but improved practices needed enhance success of future programs. Major gaps in knowledge remain,...

Seagrass meadows are considered important natural carbon sinks due to their capacity store organic (Corg) in sediments. However, the spatial heterogeneity of storage seagrass sediments needs be better understood improve accuracy Blue Carbon assessments, particularly when strong gradients present. We performed an intensive coring study within a sub-tropical estuary assess variability sedimentary Corg associated with seagrasses, and identify key factors promoting this variability. found...
Seagrass meadows support key ecosystem services, via provision of food directly for herbivores, and indirectly to their predators. The importance herbivores in seagrass has been well-documented, but the links between webs services have not previously made explicit. Herbivores interact with - including carbon sequestration, cultural values, coastal protection. Interactions can be positive or negative depend on a range factors herbivore identity grazing type intensity. There unintended...
Blue carbon ecosystems (BCE) include mangrove forests, tidal marshes, and seagrass meadows, all of which are currently under threat, putting their contribution to mitigating climate change at risk. Although certain challenges trade-offs exist, remote sensing offers a promising avenue for transparent, replicable, cost-effective accounting many BCE unprecedented temporal spatial scales. The United Nations Framework Convention on Climate Change (UNFCCC) has issued guidelines developing blue...
HIGHLIGHTS: Sedimentation of fine sediment particles onto seagrass leaves severely hampers the plants' performance in both light and darkness, due to inadequate internal plant aeration intrusion phytotoxic H2S. Anthropogenic activities leading re-suspension can have adverse effects on adjacent meadows, owing reduced availability settling suspended potentially impeding gas exchange with surrounding water. We used microsensors determine O2 fluxes diffusive boundary layer (DBL) thickness...
Better mitigation of anthropogenic stressors on marine ecosystems is urgently needed to address increasing biodiversity losses worldwide. We explore opportunities for stressor using whole-of-systems modelling ecological resilience, accounting complex interactions between stressors, their timing and duration, background environmental conditions biological processes. then search windows, times when minimally impact defined here as risk, recovery resistance. show 28 globally distributed...
Seagrasses are hugely valuable to human life, but the global extent of seagrass meadows remains unclear. As evidence their value, a United Nations program exists (http://data.unep-wcmc.org/datasets/7) try and assess distribution there has been call from 122 scientists across 28 countries for more work manage, protect monitor (http://www.bbc.com/news/science-environment-37606827). Emerging 12th International Seagrass Biology Workshop, held in October 2016 view that grazing marine megafauna...
Coastal seagrass habitats are at risk from a range of anthropogenic activities that modify the natural light environment, including dredging associated with coastal and port developments. On Australia's east coast, tropical Zostera muelleri ssp. capricorni dominates intertidal mudbanks in sheltered embayments which also preferred locations for harbours facilities. Dredging to establish maintain shipping channels these areas can degrade water quality diminish conditions required growth. Based...
Global seagrass research efforts have focused on shallow coastal and estuarine populations where alarming declines been recorded. Comparatively little is known about the dynamics of deep-water seagrasses despite evidence that they form extensive meadows in some parts world. Deep-water are subject to similar anthropogenic threats as meadows, particularly along Great Barrier Reef lagoon occur close major population centres. We examine a GBR over an 8 year period during which time capital...
Abstract Seed‐based seagrass restoration strategies demand precise understanding of the environmental drivers influencing flowering. Flowering varies across diverse spatial and temporal scales, yet drivers' effects on these dynamics have received less attention. Lack knowledge regarding this life‐history stage limits advancement seed‐based efforts, especially establishment shore‐based nurseries to enhance seed production. A systematic literature review flowering genus Zostera was conducted...
Abstract Aim The movement of propagules among plant populations affects their ability to replenish and recover after a disturbance. Quantitative data on recovery strategies, including the effectiveness population connectivity, are often lacking at broad spatial temporal scales. We use numerical modelling predict seagrass propagule dispersal settlement provide an approach for circumstances where direct, or even indirect, measures dynamics difficult establish.
