Modelling the Effects of Zostera noltei Meadows on Sediment Dynamics: Application to the Arcachon Lagoon [PDF]

open access: yesOcean Dynamics, 2014
A three-dimensional model has been modified to describe the complex interactions between hydrodynamics, sediment dynamics and biological parameters in the presence of Zostera noltei. The model treats seagrass leafs as flexible blades that bend under hydrodynamic forcing and alter the local momentum and turbulence fluxes and, therefore, the benthic ...

Toxicity effects of an environmental realistic herbicide mixture on the seagrass Zostera noltei

Environmental Pollution, 2017
Worldwide seagrass declines have been observed due to multiple stressors. One of them is the mixture of pesticides used in intensive agriculture and boat antifouling paints in coastal areas. Effects of mixture toxicity are complex and poorly understood.

Seasonal Variability of the Carbon and Nitrogen Isotopic Signature in a Zostera noltei Meadow at the NW Iberian Peninsula [PDF]

open access: yesWetlands, 2018
Nitrogen (N) and carbon (C) isotopic analyses in seagrasses have been established as effective environmental tracers to assess the anthropogenic influence on seagrass meadows. The aim of this study was to determine the spatial patterns and seasonal variability in the C and N stable isotopic composition of sediments, leaves and epiphytes at a Zostera ...

Benthic Oxygen Exchange Over a Heterogeneous Zostera noltei Meadow in a Temperate Coastal Ecosystem [PDF]

open access: yesMarine Ecology - Progress Series, 2016
Seagrass meadows support intense but highly variable benthic metabolic rates that still need to be better evaluated to determine an accurate trophic status. The present study assessed how seagrasses and associated benthic macrofauna control spatiotemporal changes in benthic oxygen exchanges within a temperate bay.

Enhancing the resilience of Zostera noltei seagrass meadows against Arenicola spp. bio-invasion: A decision-making approach

Journal of Environmental Management, 2022
Seagrass meadows provide important and valuable ecosystem services. They are affected by several natural and human-induced stressors, but a combination of natural recovery and management actions have recently inverted the worldwide reduction. The main objectives of this study were to provide science-based knowledge on ecology and restoration, framed on

Seagrass Zostera noltei as bioindicator of ecological status of Croatian transitional waters [PDF]

open access: possible, 2015
During the implementation phase of the EU Water Framework Directive, CYMOX method (Cymodocea nodosaindex) was used to determine the ecological status of Croatian transitional waters. During the monitoring program, it was found that C. nodosadoes not sufficiently inhabit some of Croatian transitional waters and that it can not be used as indicator ...

Thriving of Zostera noltei under intertidal conditions: implications for the modelling of seagrass populations

Marine Biology, 2016
The distribution of Zostera noltii seagrass in Ria de Aveiro lagoon (NW Portugal) is presently characterised by intertidal monospecific meadows. Numerical modelling approaches are useful supportive tools for environmental management, although the available numerical models for seagrasses generally overlook the intertidal processes, such as the water ...
