Can we save a marine species affected by a highly infective, highly lethal, waterborne disease from extinction?
(Biological Conservation, 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 ... -
Capacity of the potentially toxic diatoms Pseudo-nitzschia mannii and Pseudo-nitzschia hasleana to tolerate polycyclic aromatic hydrocarbons
(Ecotoxicology and Environmental Safety, 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 ... -
Carbon metabolic rates and GHG emissions in different wetland types of the Ebro Delta
(PLoS ONE, 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 ... -
Cell immunolocalization of ciguatoxin-like compounds in the benthic dinoflagellate Gambierdiscus australes M. Chinain & M.A. Faust by confocal microscopy
(Harmful Algae, 2022-11-23)Dinoflagellates of the genera Gambierdiscus and Fukuyoa are able to produce potent neurotoxins like ciguatoxins (CTXs), which, after biooxidation in fish, are responsible for ciguatera intoxication. An ... -
Changing nutrients, changing rivers
(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 ... -
Ciguatoxin Detection in Flesh and Liver of Relevant Fish Species from the Canary Islands
(Toxins, 2022-01-09)The Canary Islands are a ciguatoxin (CTX) hotspot with an established official monitoring for the detection of CTX in fish flesh from the authorised points of first sale. Fish caught by recreational ... -
Ciguatoxin-like toxicity distribution in flesh of amberjack (Seriola spp.) and dusky grouper (Epinephelus marginatus)
(Environmental Research, 2023-04-10)Ciguatoxins (CTXs) are marine neurotoxins that cause ciguatera poisoning (CP), mainly through the consumption of fish. The distribution of CTXs in fish is known to be unequal. Studies have shown that ... -
Combining an effect-based methodology with chemical analysis for antibiotics determination in wastewater and receiving freshwater and marine environment
(Environmental Pollution, 2020-12-15)Two different methodologies were combined to evaluate the risks that antibiotics can pose in the environment; i) an effect-based methodology based on microbial growth inhibition and ii) an analytical ... -
Complete mitochondrial genome of a rare diatom (Bacillariophyta) Proschkinia and its phylogenetic and taxonomic implications
(Mitochondrial DNA Part B: Resources, 2018-11-25)We obtained the complete mitogenome of Proschkinia sp. strain SZCZR1824, a strain belonging to a poorly known diatom genus with no previous molecular data. This genome is 48,863 bp long, with two group ... -
Connecting the morphological and molecular species concepts to facilitate species identification within the genus Fragilaria (Bacillariophyta)
(Journal of Phycology, 2019-05-20)This paper explores the diversity and taxonomy of species within Fragilaria sensu stricto, an abundant and ecologically important diatom genus, taking advantage of cultured and DNA ‐barcoded material. ... -
Cyclodextrin polymers as passive sampling materials for lipophilic marine toxins in Prorocentrum lima cultures and a Dinophysis sacculus bloom in the NW Mediterranean Sea
(Chemosphere, 2021-07-09)Cyclodextrins, cyclic oligomers that form a conical structure with an internal cavity, are proposed as new and sustainable materials for passive sampling of lipophilic marine toxins. Two applicability ... -
Description of Navicula vanseea sp. nov. (Naviculales, Naviculaceae), a new species of diatom from the highly alkaline Lake Van (Republic of Türkiye) with complete characterisation of its organellar genomes and multigene phylogeny
(PhytoKeys, 2024-04-08)The current article describes Navicula vanseea sp. nov., a new species of diatom from Lake Van, a highly alkaline lake in Eastern Anatolia (Türkiye). The description is based on light and scanning ... -
Detecting harmful algal blooms with isothermal molecular strategies
(Trends in Biotechnology, 2019-08-06)The use of isothermal nucleic acid amplification strategies to detect harmful algal blooms (HABs) is in its infancy. We describe recent advances in these systems and highlight the challenges for the ... -
