Drivers of variability in Blue Carbon stocks and burial rates across European e...

The implementation of climate change mitigation strategies based on the conservation and restoration of Blue Carbon ecosystems requires a deep understanding of the magnitude and variability in organic carbon (Corg) storage across and within these ecosystems. This study explored the variability in soil Corg stocks and burial rates across and within intertidal estuarine habitats of the Atlantic European coast and...

Macroalgas das Berlengas e Costa de Prata: Do conhecimento à utilização

A Costa de Prata, região litoral compreendida entre Esmoriz (Aveiro) e Torres Vedras (Lisboa), caracteriza-se, a norte, pelo domínio de praias de areia fina cortadas pelos maciços rochosos da Serra da Boa Viagem, da Nazaré e de São Martinho do Porto. Já a sul de Peniche, dominam os afloramentos rochosos, submareais e intermareais, que frequentemente emergem do mar em imponentes arribas que vincam o limite conti...

Assessment of seasonal and spatial variations in the nutritional content of six...

Bivalves are widely distributed through diverse habitats, including estuaries and coastal lagoons which are extremely productive ecosystems, and play important roles in trophic webs and in ecosystems’ biological processes. Bivalves, as well as other marine resources, have been a part of the humans’ diet since mankind started fishing. These resources have high nutritional values, being constituted by high protei...

The effects of the invasive seaweed Asparagopsis armata on native rock pool com...

Biological invasions represent a threat to ecosystems, through competition and habitat destruction, which may result in significant changes of the invaded community. Asparagopsis armata Harvey 1855 is a red macroalgae (Rodophyta) globally recognized as an invasive species. It is found from the intertidal to shallow subtidal areas, on rock or epiphytic, forming natural vegetation belts on exposed coasts. This st...

Invasive Seaweeds in the Iberian Peninsula: A Contribution for Food Supply

The introduction of exotic organisms in marine ecosystems can lead to economic and ecological losses. Globally, seaweeds represent a significant part of these non-indigenous species (NIS), with 407 introduced algal species. Furthermore, the presence of NIS seaweeds has been reported as a major concern worldwide since the patterns of their potential invasion mechanisms and vectors are not yet fully understood. C...

Indicator-Based Assessment of Marine Biological Diversity–Lessons from 10 Case ...

The Marine Strategy Framework Directive requires the environmental status of European marine waters to be assessed using biodiversity as 1 out of 11 descriptors, but the complexity of marine biodiversity and its large span across latitudinal and salinity gradients have been a challenge to the scientific community aiming to produce approaches for integrating information from a broad range of indicators. The Nest...

Tales from a thousand and one ways to integrate marine ecosystem components whe...

Assessing the environmental status of marine ecosystems is useful when communicating key messages to policymakers or the society, reducing the complex information of the multiple ecosystem and biodiversity components and their important spatial and temporal variability into manageable units. Taking into account the ecosystem components to be addressed (e.g., biological, chemical, physical), the numerous biodive...

Good Environmental Status of marine ecosystems: What is it and how do we know w...

The European Marine Strategy Framework Directive (MSFD) requires EU Member States (MS) to achieve Good Environmental Status (GEnS) of their seas by 2020. We address the question of what GEnS entails especially with regard to the level at which targets are set (descriptors, criteria, indicators), to scales for assessments (regional, sub-divisions, site-specific), and to difficulties in putting into practice the ...
