Environmental controls on carbon sequestration, sediment accretion, and elevation change in the Ebro River Delta: Implications for wetland restoration
(Elsevier, 2019-03-26)
Delta wetlands are increasingly recognized as important sinks for ‘blue carbon,’ although this and other ecosystem services that deltas provide are threatened by human activities. We investigated factors ...
Seagrass epiphytic assemblages are strong indicators of agricultural discharge but weak indicators of host features
(Elsevier, 2018-03-02)
Wastewater pulses from rice agriculture are persistently discharged into the northern shore of the Alfacs Bay (Ebro Delta, NW Mediterranean) from April to November. The bay also receives water from ...
Avoiding quantification bias in metabarcoding: Application of a cell biovolume correction factor in diatom molecular biomonitoring
(Wiley, 2017-12-26)
In recent years, remarkable progress has been made in developing environmental DNA metabarcoding. However, its ability to quantify species relative abundance remains uncertain, limiting its application ...
Colorimetric DNA-based assay for the specific detection and quantification of Ostreopsis cf. ovata and Ostreopsis cf. siamensis in the marine environment
(Elsevier, 2019-03-16)
Ostreopsis is a toxic benthic dinoflagellate largely distributed worldwide in tropical and temperate areas. In the Mediterranean Sea, periodic summer blooms have been reported and have become a serious ...
Detection of azaspiracids in mussels using electrochemical immunosensors for fast screening in monitoring programs
(Elsevier, 2018-02-06)
Given the widespread occurrence of azaspiracids (AZAs), it is clearly necessary to advance in simple and low-cost methods for the rapid detection of these marine toxins in order to protect seafood ...
Dual quantitative PCR assay for identification and enumeration of Karlodinium veneficum and Karlodinium armiger combined with a simple and rapid DNA extraction method
(Springer, 2018-04-04)
Karlodinium is a dinoflagellate genus responsible for massive fish mortality events worldwide. It is commonly found in Alfacs Bay (NW Mediterranean Sea), where the presence of two Karlodinium species ...
The role of forest maturity in extreme hydrological events
(Wiley, 2018-02-10)
This study aims to clarify the influence of forests, as well as other prevalent land cover types, on extreme hydrological events through a land cover gradient design. We selected 10 catchments within a ...
Basin-scale land use impacts on world deltas: Human vs natural forcings
(Elsevier, 2018-12-14)
A new global database of 86 deltas and river basins was analyzed to investigate the relative importance of deforestation and land use changes versus natural forcings in determining long-term total delta ...
Bioaccessibility of lipophilic and hydrophilic marine biotoxins in seafood: An in vitro digestion approach
(Elsevier, 2019-04-28)
This study aimed to assess the bioaccessibility of different marine biotoxins in naturally contaminated shellfish and fish gonads using an in vitro digestion methodology. In general, hydrophilic toxins ...
Detection of tetrodotoxins in juvenile pufferfish Lagocephalus sceleratus (Gmelin, 1789) from the North Aegean Sea (Greece) by an electrochemical magnetic bead-based immunosensing tool
(Elsevier, 2019-03-29)
Two small Lagocephalus sceleratus juveniles were captured in picarel targeting catches from North Aegean Sea (Greece) in the autumn of 2017. An electrochemical immunosensing tool using magnetic beads ...
