Silver nanoparticle toxicity effect on the seagrass Halophila stipulacea
Ecotoxicology and Environmental Safety, 2020 Information on silver nanoparticle (AgNP) phytotoxicity on seagrasses is provided for the first time. Toxic effects of environmentally relevant AgNP concentrations on Halophila stipulacea were assessed to identify sensitive biomarkers, to determine threshold effect concentrations and to evaluate potential risks.

Drivers of the Low Metabolic Rates of Seagrass Meadows in the Red Sea
Frontiers in Marine Science, 2020 Tropical seagrass meadows are highly productive ecosystems that thrive in oligotrophic environments. The Red Sea is characterized by strong N–S latitudinal nutrient and temperature gradients, which constrain pelagic productivity.

The capabilities of Sentinel-MSI (2A/2B) and Landsat-OLI (8/9) in seagrass and algae species differentiation using spectral reflectance [PDF]
Ocean Science, 2022 This paper assesses the reflectance difference values between the respective spectral bands in the visible and near-infrared (VNIR) of Sentinel 2A/2B Multi-Spectral Instrument (MSI) and Landsat 8/9 Operational Land Imager (OLI) sensors for seagrass ...

Distribution of the seagrass Halophila stipulacea: A big jump to the northwestern Mediterranean Sea
Aquatic Botany, 2022 Abstract The Red Sea and Indian Ocean seagrass Halophila stipulacea entered the Mediterranean in the late 19th century via the Suez Canal. Here, we report on the discovery of a population of H. stipulacea covering 16.5 ha off the harbour of Cannes, French Riviera, France.

Warming enhances carbon dioxide and methane fluxes from Red Sea seagrass (Halophila stipulacea) sediments [PDF]
Biogeosciences, 2020 Seagrass meadows are autotrophic ecosystems acting as carbon sinks, but they have also been shown to be sources of carbon dioxide (CO2) and methane (CH4).

Occurrence of the alien seagrass Halophila stipulacea in Martinique (French West Indies) [PDF]
Marine Biodiversity Records, 2013 The occurrence of the tropical seagrass Halophila stipulacea (Hydrocharitaceae) is recorded for the first time on the Caribbean coast of Martinique (French West Indies, Caribbean Sea). Specimens were observed, since a large survey in 2006, on sandy substrates between 3 m and 32 m depths in this area.

eDNA Reveals the Associated Metazoan Diversity of Mediterranean Seagrass Sediments
Diversity, 2022 Anthropogenic impacts on marine ecosystems have led to a decline of biodiversity across the oceans, threatening invaluable ecosystem services on which we depend. Ecological temporal data to track changes in diversity are relatively rare, and the few long-
