Maximising environmental pressure-response relationship signals from diatom-based metabarcoding in rivers
(Elsevier, 2023-12-28)
DNA metabarcoding has been performed on a large number of river phytobenthos samples collected from the UK, using rbcL primers optimised for diatoms. Within this dataset the composition of non-diatom ...
Evaluation of the occurrence and fate of pesticides in a typical Mediterranean delta ecosystem (EBRO RIVER delta) and risk assessment for aquatic organisms
(Elsevier, 2020-10-14)
Delta ecosystems are areas of high ecologic and economic values, where wildlife commonly shares the territory with intensive agricultural activities, particularly, rice cultivation and seafood production. ...
Seasonal patterns of settlement and growth of introduced and native ascidians in bivalve cultures in the Ebro Delta (NE Iberian Peninsula)
(Elsevier, 2017-11-13)
Ascidians are important both as invasive species and as a fouling group in artificial marine habitats, causing negative impacts in aquaculture settings and the surrounding environment. The Ebro Delta ...
Addressing the analytical challenges for the detection of ciguatoxins using an electrochemical biosensor
(American Chemical Society, 2020-03-05)
The importance of ciguatoxins (CTXs) in seafood safety and their emerging occurrence in locations far away from tropical areas highlight the need for simple and low-cost methods for the sensitive and ...
A fast magnetic bead-based colorimetric immunoassay for the detection of tetrodotoxins in shellfish
(Elsevier, 2020-04-05)
Tetrodotoxin (TTX) is a potent neurotoxin responsible for many food poisoning incidents and some fatalities. Although mainly associated with the consumption of pufferfish, in recent years, TTX has been ...
The combined use of chemical and biochemical markers in Rutilus rutilus to assess the effect of dredging in the lower course of the Ebro River
(Elsevier, 2018-02-26)
The lower course of the Ebro River is polluted with high concentrations of organochlorine compounds dumped by a chloro-alkali plant during the last century. A remediation plan, including building of a ...
A rapid cleaning method for diatoms
(Taylor & Francis, 2019-07-18)
We describe here a protocol for cleaning diatoms when time is short and the amount of
sample is very limited. Essentially, the method consists of drying material onto coverslips and
cleaning it directly ...
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 ...
Enhanced diversity of aquatic macroinvertebrate predators and biological pest control but reduced crop establishment in organic rice farming
(Elsevier, 2023-08-10)
Organic farming has been adopted as the main alternative to reduce the environmental impact of intensive agriculture by banning the use of synthetic inputs and bolstering key ecological functions such ...
Electrochemical genosensor for the direct detection of tailed PCR amplicons incorporating ferrocene labelled dATP
(Elsevier, 2019-03-30)
An electrochemical genosensor for the detection and quantification of Karlodinium armiger is presented. The genosensor exploits tailed primers and ferrocene labelled dATP analogue to produce PCR products ...
