Guidelines for model adaptation: A study of the transferability of a general seagrass ecosystem Dynamic Bayesian Networks model [PDF]
Ecology and Evolution, 2022 In general, it is not feasible to collect enough empirical data to capture the entire range of processes that define a complex system, either intrinsically or when viewing the system from a different geographical or temporal perspective. In this context,

Use of hyperspectral reflectance to non-destructively estimate seagrass Zostera noltei biomass
Ecological Indicators, 2021 Seagrasses are marine plants ranked worldwide amongst the most valuable coastal ecosystems. The global conservation effort requires accurate estimation of seagrass abundance and taxonomic composition.

DiversityNon-structural carbohydrates (NSCs) are energetic compounds that can be accumulated in tissues and mobilized during periods of unfavorable conditions to maintain the biological functions of plants. The balance of these biochemical compounds is controlled

Scientia Marina, 2017 Seagrass beds are among the most valuable ecosystems in the world but they are also among the ones most affected by human activities, and they have decreased significantly in recent decades.

Modelling the effects of Zostera noltei meadows on sediment dynamics: application to the Arcachon lagoon [PDF]
Ocean 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 ...

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

Interaction between Ammonium Toxicity and Green Tide Development Over Seagrass Meadows: A Laboratory Study. [PDF]
PLoS ONE, 2016 Eutrophication affects seagrasses negatively by increasing light attenuation through stimulation of biomass of fast-growing, bloom-forming algae and because high concentrations of ammonium in the water can be toxic to higher plants.

Benthic oxygen exchange over a heterogeneous Zostera noltei meadow in a temperate coastal ecosystem [PDF]
Marine 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.

Effects of ocean acidification and hydrodynamic conditions on carbon metabolism and dissolved organic carbon (DOC) fluxes in seagrass populations. [PDF]
PLoS ONE, 2018 Global change has been acknowledged as one of the main threats to the biosphere and its provision of ecosystem services, especially in marine ecosystems.
