Effects of a severe storm on seagrass meadows

Science of The Total Environment, 2020
Extreme environmental events can strongly affect coastal marine ecosystems but are typically unpredictable. Reliable data on benthic community conditions before such events are rarely available, making it difficult to measure their effects. At the end of October 2018, a severe storm hit the Ligurian coast (NW Mediterranean) producing damages to coastal

Seagrass Community Metabolism: Assessing the Carbon Sink Capacity of Seagrass Meadows [PDF]

Global Biogeochemical Cycles, 2010
The metabolic rates of seagrass communities were synthesized on the basis of a data set on seagrass community metabolism containing 403 individual estimates derived from a total of 155 different sites. Gross primary production (GPP) rates (mean ± SE = 224.9 ± 11.1 mmol O 2 m

Seagrass contributes substantially to the sedimentary lignin pool in an estuarine seagrass meadow

Science of The Total Environment, 2021
Shallow coastal ecosystems are reservoirs of carbon derived from allochthonous organic matter and autochthonous organic matter produced by microalgae and macrophytes. Carbon stored in vegetated coastal ecosystems has attracted broad attention as an important component of carbon sinks.

Mangrove Forests and Seagrass Meadows

2020
This chapter discusses mangrove forests and seagrass meadows. These represent two of the most valuable marine habitats in the world, important for providing a high level of productivity and physical structure that support a considerable biodiversity of associated animals. However, both systems are remarkable in that they are based on higher plants more

Seagrass Meadows of Northeastern Australia

2016
The northeastern Australian coastline from the tropics (10°S) to the subtropical zone of the southern Great Barrier Reef (GBR) and its World Heritage Area (25°S) is famous for coral reefs, a huge drawcard for the Australian tourist industry. Less appreciated but of at least equal importance to ecosystem functionality are the enormous seagrass meadows ...

Disturbance influences the invasion of a seagrass into an existing meadow

Marine Pollution Bulletin, 2014
Future impacts from climate change and human activities may increase the likelihood of invasions of native marine species into existing habitats as a result of range shifts. To provide an understanding of the invasion of a native seagrass species (Syringodium isoetifolium) into a tropical multi-species meadow, detailed field assessments were conducted ...

Dynamics of Seagrass Meadows on the Swedish Skagerrak Coast

AMBIO: A Journal of the Human Environment, 2009
Seagrasses have declined in many places around the world, and the Swedish Skagerrak coast is no exception. Between the 1980s and 2000, the cover of eelgrass (Zostera marina L.) on the Swedish Skagerrak coast decreased about 60%. In the present study, the sites that were investigated in the 1980s and 2000 were revisited (1655 ha) in 2003 and 2004 to ...

Herbivory in Seagrass Meadows: an Evolving Paradigm

Estuaries and Coasts, 2020
In the past few decades, we have learned much about the factors that regulate the productivity of seagrass-dominated ecosystems, especially those at low latitudes. Here, we update our previous assessments of the importance of seagrass-herbivore interactions, focusing on recent studies that have examined (1) the diversity of herbivores feeding on live ...

Light and Photosynthesis in Seagrass Meadows

2006
The distribution of radiant energy in plant canopies determines one of the fundamental interactions of biophysical ecology—that of energy exchange between photosynthetic organisms and their environment. Accurate knowledge of light absorption by plant canopies permits the calculation of important plantand ecosystem-level properties, including rates of ...

On the Wave Attenuation Properties of Seagrass Meadows [PDF]

Coastal Engineering
The wave attenuation properties of seagrass meadows were investigated in a flume facility using dynamicallyscaled models of seagrass exposed to regular long crested waves. Experiments were conducted for 66 wave conditions and with four plant densities; waves were measured with eight resistance wave gauges.
