Presence of CTXs in moray eels and dusky groupers in the marine environment of the Canary Islandsds
(Elsevier, 2020-01-31)
Local population frequently consumes moray eels and dusky groupers from the Canary Islands. These species are top predators and the interactions between them include predation but also, in some cases, ...
Evaluation and sensitivity analysis of diatom DNA metabarcoding for WFD bioassessment of Mediterranean rivers
(Elsevier, 2020-04-04)
Our study of 164 diatom samples from Catalonia (NE Spain) is the first to evaluate the applicability of DNA metabarcoding, based on high throughput sequencing (HTS) using a 312-bp rbcL marker, for ...
Driving factors of biogeographical variation in seagrass herbivory
(Elsevier, 2020-11-25)
Despite the crucial role of herbivory in shaping community assembly, our understanding on biogeographical patterns of herbivory on seagrasses is limited compared to that on terrestrial plants. In ...
The taxonomy and diversity of Proschkinia (Bacillariophyta), a common but enigmatic genus from marine coasts
(Wiley, 2020-04-07)
Detailed morphological documentation is provided for established Proschkinia taxa, including the generitype, P. bulnheimii, and P. complanata, P. complanatula, P. complanatoides and P. hyalosirella, and ...
Can we save a marine species affected by a highly infective, highly lethal, waterborne disease from extinction?
(Elsevier, 2020-03-18)
Anthropogenic drivers and global warming are altering the occurrence of infectious marine diseases, some of which produce mass mortalities with considerable ecosystemic and economic costs. The Mediterranean ...
Prey size and species preferences in the invasive blue crab, Callinectes sapidus: Potential effects in marine and freshwater ecosystems
(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) ...
Development of a novel metric for evaluating diatom assemblages in rivers using DNA metabarcoding
(Elsevier, 2020-08-10)
Fundamental differences in the nature of diatom assemblage composition data generated using light microscopy and molecular barcoding create problems when applying current paradigms and metrics developed ...
Detoxification of paralytic shellfish poisoning toxins in naturally contaminated mussels, clams and scallops by an industrial procedure
(Elsevier, 2020-05-04)
Paralytic shellfish poisoning (PSP) episodes cause important economic impacts due to closure of shellfish production areas in order to protect human health. These closures, if are frequent and persistent, ...
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 ...
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 ...
