Evaluating the extent and impact of the extreme Storm Gloria on Posidonia oceanica seagrass meadows
(Elsevier, 2023-11-07)
Extreme storms can trigger abrupt and often lasting changes in ecosystems by affecting foundational (habitat-forming) species. While the frequency and intensity of extreme events are projected to increase ...
Environmental typology of rivers from the Brazilian semiarid as a first step for the application of the index of biotic integrity: The case of the Chapada Diamantina
(Wiley, 2020-03-02)
Defining environmental river types is an essential step in the development of accurate fish‐based methods (IBI, Index of Biotic Integrity) to assess the environmental quality of aquatic ecosystems. In ...
Evaluating adaptation options to sea level rise and benefits to agriculture: The Ebro Delta showcase
(Elsevier, 2021-09-28)
Sea level rise (SLR) is threatening low-lying coastal areas such as river deltas. The Ebro river Delta (Spain) is representative of coastal systems particularly vulnerable to SLR due to significant ...
Feeding Habits and Short-Term Mobility Patterns of Blue Crab, Callinectes sapidus, Across Invaded Habitats of the Ebro Delta Subjected to Contrasting Salinity
(Springer, 2021-09-28)
The blue crab Callinectes sapidus was first observed in the Ebro Delta in 2012 and since then captures have increased exponentially up to over 2 t per day, while its presence remains low in other ...
Not all nudibranchs are carnivorous: trophic ecology of Polycerella emertoni in the Ebro Delta
(Inter Research, 2020-07-09)
Nudibranchs have always been regarded as a group of specialized predators. In Alfacs Bay (Ebro Delta, Spain), the cryptic nudibranch Polycerella emertoni is found associated with the pseudo-indigenous ...
Detection of Ostreopsis cf. ovata in environmental samples using an electrochemical DNA-based biosensor
(Elsevier, 2019-06-28)
Ostreopsis cf. ovata is a benthic microalga distributed in tropical and temperate regions worldwide which produces palytoxins (PlTXs). Herein, an electrochemical biosensor for the detection of this toxic ...
Multipathogen infections and multifactorial pathogenesis involved in noble pen shell (Pinna nobilis) mass mortality events: Background and current pathologic approaches
(SAGE Publications, 2023-07-17)
Disease outbreaks in several ecologically or commercially important invertebrate marine species have been reported in recent years all over the world. Mass mortality events (MMEs) have affected the noble ...
The role of rice fields and constructed wetlands as a source and a sink of pesticides and contaminants of emerging concern: Full-scale evaluation
(Elsevier, 2020-07-17)
Urban, industrial, and agricultural development in river basins has resulted in the pollution of estuarine and coastal ecosystems with a great amount of organic microcontaminants (OMCs) such as pesticides ...
Cyclodextrin polymer clean-up method for the detection of ciguatoxins in fish with cell-based assays
(Elsevier, 2022-09-13)
Ciguatoxins (CTXs) are marine toxins produced by microalgae of the genera Gambierdiscus and Fukuyoa, which are transferred through the food webs, reaching humans and causing a poisoning known as ciguatera. ...
Development and validation of a maleimide-based enzyme-linked immunosorbent assay for the detection of tetrodotoxin in oysters and mussels
(Elsevier, 2017-08-18)
The recent detection of tetrodotoxins (TTXs) in puffer fish and shellfish in Europe highlights the necessity to monitor the levels of TTXs in seafood by rapid, specific, sensitive and reliable methods ...
