Article
Full-text available
Microphytobenthos (MPB), the photosynthetic primary producing component of microbenthos, shows variable patterns in its biomass distribution along the intertidal gradient as a result of the interactions of factors such as light, tides, temperature, and grazing pressure. These patterns have been studied more extensively in northern European estuarie...

Full-text available
Diel primary production patterns of intertidal microphytobenthos (MPB) have been attributed to short-term physiological changes in the photosynthetic apparatus or to diel changes in the photoautotrophic biomass in the sediment photic layer due to vertical migration. Diel changes in primary production and vertical migration are entrained by external...
Article

Irradiance and temperature variations during tidal cycles modulate microphytobenthic primary production potentially by changing the radiative energy balance of photosynthetic mats between immersion and emersion and thus sediment daily net metabolism. To test the effect of tidal stages on the radiative energy budget, we used microsensor measurements...

Self-shading is widely known for primary producers, but it has been not addressed in detail for microphytoben-thos (MPB). Upper layers of MPB biomass limit light availability to the layers below, reducing the thickness of the photic layer within the sediment (zphot) and likely limiting MPB primary production and growth. To test this hypothesis, we...

En el presente trabajo se cultivó un bloom de microalgas en un fotobiorreactor piloto tipo high rate algae pond (HRAP), con un volumen de 450 l. Éste se operó en discontinuo, con un medio sintético y bajo condiciones ambientales de luz y temperatura. El objetivo era utilizar un modelo cinético que predijera las velocidades de crecimiento de biomasa...

Understanding macroalgal bloom development is crucial for managing eutrophication and protecting estuarine ecosystems. In this study, brown macroalgal blooms (i.e., golden tides) were identified in a potentially eutrophic temperate estuary (NW Ireland). Pylaiella littoralis (Phaeophyceae, Ectocarpales) was monitored at low tide over seven sampling...

Full-text available
Epipelic, biofilm-forming diatoms are key drivers of the primary production of mudflats. Such primary production is strongly affected by the vertical migration of diatoms, which is modulated by diurnal photoperiods, tidal cycles, and photoprotection mechanisms. However, the role of vertical migration in the radiative energy budget (REB) of microphy...

Massive accumulations of invasive brown algae Rugulopteryx okamurae are exacerbating environmental and socio-economic issues on the Mediterranean and potentially Atlantic coasts. These golden tides, likely intensified by global change processes such as changes in wind direction and intensity and rising temperatures, pose increasing challenges to co...

Seagrass restoration, necessitating knowledge of site environmental conditions, appropriate planting methods, and the identification of suitable locations for seagrass growth, is the focal point of this study. The tracking of the spatio-temporal distribution of seagrasses, which is essential for pinpointing areas of persistence, loss, and recent ex...

Golden seaweed tides are a global environmental and socioeconomic problem, that have been occurring along Ireland's eastern coastline since the 1990s. This study focused on analysing the spatiotemporal dynamics of golden seaweed tides (Ectocarpus siliculosus) at Dollymount Strand in Dublin Bay (Ireland), between 2016 and 2022, and its relationship...

Golden seaweed tides are a global environmental and social problem, that have been occurring along Ireland's eastern coastline since the 1990s. This study focused on analysing the spatiotemporal dynamics of golden seaweed (Ectocarpus siliculosus) coverage at Dollymount Strand in Dublin Bay (Ireland), between 2016 and 2022, and its relationship with...

Eutrophication is still a serious problem in many coastal areas, including the tropics, where river discharges of nutrients is usually high. The ecological stability and ecosystem services of the Mesoamerican Barrier Reef System (MBRS), the world's second-largest coral reef system, suffer a generalized impact by riverine discharge of sediment and o...
Article
In intertidal areas, the zonation is determined by factors such as sea-level and topography. For this reason, a mixed methodology for the characterization (topography, extension, and zonation) of maximum intertidal areas is presented, based upon multispectral satellite imagery, hydrodynamic modeling, and in situ measurements. The methodology is app...

Human activities coupled with climate change impacts are becoming the main factors in decreasing inland surface water quantity and quality, leading to the disturbance of the aquatic ecological balance. Under such conditions, the introduction and proliferation of aquatic invasive alien species are more likely to occur. Hence, frequent surface water...

Microphytobenthos (MPB) provides important ecosystem functions and services, contributing significantly to the total primary production in shallow coastal ecosystems. However, determining the factors that regulate the seasonal changes of MPB and its distribution patterns at larger scales is hindered by the considerable spatial and temporal variabil...

Microphytobenthos (MPB) plays a key role in the cycling of carbon and nitrogen in shallow estuaries and intertidal areas, contributing up to 50% of primary production. In the inner Cadiz Bay, the intertidal zone covers ~60% of its surface. Therefore, it is important to study the spatial and seasonal variability of microphytobenthic net primary prod...

Irradiance and temperature changes during tidal cycles affect microphytobenthic primary production potentially changing the radiative energy balance in the photosynthetic biofilm between immersion and emersion. To test this hypothesis, we estimated for the first time the radiative energy budget in a photosynthetic microbial mat during immersion and...
