Electrochemical biosensor for the dual detection of Gambierdiscus australes and Gambierdiscus excentricus in field samples. First report of G. excentricus in the Balearic Islands
(Elsevier, 2021-10-13)
Several genera of marine dinoflagellates are known to produce bioactive compounds that affect human health. Among them, Gambierdiscus and Fukuyoa stand out for their ability to produce several toxins, ...
Use of a hydrodynamic model for the management of water renovation in a coastal system
(European Geosciences Union (EGU), 2019-03-04)
In this contribution we investigate the hydrodynamic response in Alfacs Bay (Ebro Delta, NW Mediterranean Sea) to different anthropogenic modifications in freshwater flows and inner bay–open sea ...
Determining geographical range and alien status in diatoms: three instructive case histories of species newly recorded in the British Isles, including a non-native marine species from the Pacific, Diademoides luxuriosa
(Taylor & Francis Group, 2022-08-16)
Three benthic diatom species – Diademoides luxuriosa, Navicula entoleia and Nitzschia ocellata – have been discovered for the first time in Scottish coastal waters. All are highly distinctive but rarely ...
Drivers of variation in seagrass-associated amphipods across biogeographical areas
(Elsevier, 2023-02-10)
Amphipods are one of the dominant epifaunal groups in seagrass meadows. However, our understanding of the biogeographical patterns in the distribution of these small crustaceans is limited. In this ...
Living on the Edge: Demography of the Slender-Billed Gull in the Western Mediterranean
(Public Library of Science, 2014-03-24)
Small and peripheral populations are typically vulnerable to local extinction processes but important for the metapopulation dynamics of species. The Slender-billed gull (Chroicocephalus genei) is a ...
Dependence of sediment sorting on bedload transport phase in a river meander
(Wiley, 2018-03-05)
It is widely recognized nowadays that there are at least two different phases of bedload sediment transport in gravel‐bed rivers. However, the transition between these phases is still poorly or subjectively ...
Factors driving the seasonal dynamics of Pseudo-nitzschia species and domoic acid at mussel farming in the SW Mediterranean Sea
(Taylor and Francis, 2019-10-17)
The seasonal variations in Pseudo-nitzschia species and domoic acid (DA) concentration were investigated, at three shellfish farms in SW coastal Mediterranean. In parallel, the toxicity of mussels was ...
Detection of Ciguatoxins and Tetrodotoxins in Seafood with Biosensors and Other Smart Bioanalytical Systems
(MDPI, 2023-05-18)
The emergence of marine toxins such as ciguatoxins (CTXs) and tetrodotoxins (TTXs) in non-endemic regions may pose a serious food safety threat and public health concern if proper control measures are ...
Structural and functional responses of invertebrate communities to climate change and flow regulation in alpine catchments
(Wiley, 2019-01-30)
Understanding and predicting how biological communities respond to climate change is critical for assessing biodiversity vulnerability and guiding conservation efforts. Glacier‐ and snow‐fed rivers are ...
Pesticides in sediments of the Ebro River Delta cultivated area (NE Spain): Occurrence and risk assessment for aquatic organisms
(Elsevier, 2022-04-06)
Intense agricultural activities are performed in the Ebro River Delta (NE Spain) with extensive use of pesticides. Medium to highly polar pesticides have not been studied intensively in sediments despite ...
