A polyphasic approach to the study of the genus Nitzschia (Bacillariophyta): three new planktonic species from the Adriatic Sea
(Wiley, 2020-10-21)
The paraphyletic diatom genus Nitzschia comprises over 1000 morphologically distinct pennate taxa, known from the benthos and plankton of freshwater, brackish and marine environments. The principal ...
Normalized abundance spectra of fish community reflect hydro-peaking on a Mediterranean large river
(Elsevier, 2018-10-19)
The European Water Framework Directive requires the integration of body size characters as an important part of fish-based bioassessment tools for freshwaters ecological status determination. The study ...
Life history traits of Mediterranean brown trout (Salmo trutta complex) in Pyrenean headwater streams
(Springer, 2022-03-25)
The Mediterranean brown trout (Salmo trutta complex) is native to basins draining to the Western Mediterranean Sea, and natural populations are currently declining in abundance and distribution due to ...
Rapid detection of ciguatoxins in Gambierdiscus and Fukuyoa with immunosensing tools
(Elsevier, 2020-08-05)
Consumption of seafood contaminated with ciguatoxins (CTXs) leads to a foodborne disease known as ciguatera. Primary producers of CTXs are epibenthic dinoflagellates of the genera Gambierdiscus and ...
Changing nutrients, changing rivers
(American Association for the Advancement of Science, 2019-08-16)
Eutrophication—the excessive enrichment of a body of water with nutrients such as nitrogen (N) and phosphorus (P)—is Earth's most widespread problem for water quality (1, 2). Growing evidence suggests ...

(Elsevier, 2020-08-29)
The blue crab, Callinectes sapidus is an invasive species in the Mediterranean region. In Ebro Delta bays, it poses an important risk for the cultivation of Mediterranean mussel (Mytillus galloprovincialis) ...
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, ...
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 ...
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 ...
