Ciguatoxin occurrence in food-web components of a Cuban Coral Reef Ecosystem: Risk-assessment implications
(MDPI, 2019-12-11)
In Cuba, ciguatera poisoning associated with fish consumption is the most commonly occurring non-bacterial seafood-borne illness. Risk management through fish market regulation has existed in Cuba for ...
Assessment of a novel microalgae-cork based technology for removing antibiotics, pesticides and nitrates from groundwater
(Elsevier, 2022-04-29)
Groundwater pollution has increased in recent years due to the intensification of agricultural and livestock activities. This results in a significant reduction in available freshwater resources. Here, ...
Trophic plasticity in the sea urchin Paracentrotus lividus, as a function of resource availability and habitat features
(Inter Research, 2020-03-05)
Factors controlling herbivory pressure are of central importance in shaping the seascape. In the Mediterranean, the sea urchin Paracentrotus lividus is considered as a keystone herbivore in seagrass ...
Identification of ciguatoxins in a shark involved in a fatal food poisoning in the Indian Ocean
(Nature Research, 2017-08-15)
Severe food poisoning events after the consumption of sharks have been reported since the 1940s;
however, there has been no clear understanding of their cause. Herein, we report for the frst time ...
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 ...
Characterization of stress coping style in Senegalese sole (Soleasenegalensis) juveniles and breeders for aquaculture
(The Royal Society, 2016-11-01)
The aim of this work was to characterize stress coping styles of Senegalese sole (Solea senegalensis) juveniles and breeders and to select an operational behavioural screening test (OBST) that can be ...
Capacity of the potentially toxic diatoms Pseudo-nitzschia mannii and Pseudo-nitzschia hasleana to tolerate polycyclic aromatic hydrocarbons
(Elsevier, 2021-03-12)
This study investigates the effects of polycyclic aromatic hydrocarbons (PAHs) on two potentially toxic Pseudo-nitzschia hasleana and P. mannii, isolated from a PAH contaminated marine environment. Both ...
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 ...
Assessment of marine benthic diatom communities: insights from a combined morphological–metabarcoding approach in Mediterranean shallow coastal waters
(Elsevier, 2022-01-18)
We investigated the advantages and disadvantages of light microscope (LM)-based identifications and DNA metabarcoding, based on a 312-bp rbcL marker, for examining benthic diatom communities from ...
Carbon metabolic rates and GHG emissions in different wetland types of the Ebro Delta
(Public Library of Science, 2020-04-22)
Deltaic wetlands are highly productive ecosystems, which characteristically can act as C-sinks. However, they are among the most threatened ecosystems, being very vulnerable to global change, and require ...
