Citizen Science Driven Big Data Collection Requires Improved and Inclusive Societal Engagement

open access: yesFrontiers in Marine Science, 2021
Marine ecosystems are in a state of crisis worldwide due to anthropogenic stressors, exacerbated by generally diminished ocean literacy. In other sectors, big data and technological advances are opening our horizons towards improved knowledge and ...

A Critical Gap in Seagrass Protection: Impact of Anthropogenic Off-Shore Nutrient Discharges on Deep Posidonia oceanica Meadows

open access: yesPlants, 2023
In the Mediterranean, anthropogenic pressures (specifically those involving nutrient loads) have been progressively moved to deeper off-shore areas to meet current policies dealing with the protection of marine biodiversity (e.g., European Directives ...

Demersal Fish Assemblages in NE Atlantic Seagrass and Kelp

open access: yesDiversity, 2020
Global fisheries are in decline, calling for urgent evidence-based action. One such action is the identification and protection of fishery-associated habitats such as seagrass meadows and kelp forests, both of which have suffered long-term loss and ...

Decreasing seagrass density negatively influences associated fauna [PDF]

open access: yesPeerJ, 2015
Seagrass meadows globally are disappearing at a rapid rate with physical disturbances being one of the major drivers of this habitat loss. Disturbance of seagrass can lead to fragmentation, a reduction in shoot density, canopy height and coverage, and ...

Spatial Patterns and Overlap of Sedimentary and Rhizosphere Microbiomes of the Seagrass Zostera capensis. [PDF]

open access: yesEnviron Microbiol Rep
Sedimentary microbiomes and, for the first time, rhizosphere microbiomes of Zostera capensis, South Africa's most abundant seagrass, were characterised using 16S rRNA metabarcoding across three estuaries. After accounting for seawater‐derived microbes, we found that sediment and rhizosphere communities largely overlapped but also harbor distinct core ...

The light requirements for growth and photosynthesis in seagrasses with emphasis on Texas estuaries : a literature survey [PDF]

open access: yes, 1993
During the last 20 years, seagrass communities throughout the world have experienced decreased productivity and distribution. These declines have often been attributed to decreased water transparency as a result of turbidity or shading by epiphytic algae.

Effects of harvesting methods on sustainability of a bay scallop fishery: dredging uproots seagrass and displaces recruits [PDF]

open access: yes, 2005
Fishing is widely recognized to have profound effects on estuarine and marine ecosystems (Hammer and Jansson, 1993; Dayton et al., 1995). Intense commercial and recreational harvest of valuable species can result in population collapses of target and ...

Historical Analysis Exposes Catastrophic Seagrass Loss for the United Kingdom

open access: yesFrontiers in Plant Science, 2021
The spatial extent of seagrass is poorly mapped, and knowledge of historical loss is limited. Here, we collated empirical and qualitative data using systematic review methods to provide unique analysis on seagrass occurrence and loss in the United ...

Sowing the Seeds of Seagrass Recovery Using Hessian Bags

open access: yesFrontiers in Ecology and Evolution, 2019
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 ...

Pigment and fatty acid profiling reveal differences in epiphytic microphytes among tropical Thalassodendron ciliatum meadows

open access: yes, 2020
Tropical seagrasses support abundant and diverse epiphytic microalgae that form the base of seagrass food webs. To help better understand the influence of structural variability of tropical seagrass meadows on associated microalgal epiphytes, we ...
