Detecting harmful algal blooms with nucleic acid amplification-based biotechnological tools
(Elsevier, 2020-08-10)
Harmful algal blooms (HABs) represent a growing threat to aquatic ecosystems and humans. Effective HAB management and mitigation efforts strongly rely on the availability of timely and in-situ tools for ...
Distribution, identification and cytotoxicity of Gambierdiscus (Dinophyceae) in the Atlantic Selvagens Islands (Madeira, Portugal): a ciguatera gateway to Europe
(Taylor & Francis Group, 2022-07-18)
The emerging threat of ciguatera poisoning (CP) in Europe has been associated with fish captured in the Canary Islands (Spain) and Selvagens Islands (Portugal). The first are heavily populated islands ...
Pinna nobilis in suboptimal environments are more tolerant to disease but more vulnerable to severe weather phenomena
(Elsevier, 2020-11-30)
We examined a disease outbreak of the fan mussel, Pinna nobilis (L.), in the Alfacs Bay (South Ebro Delta, Spain) during a period of two years in three zones exposed to a summer salinity gradient resulting ...
Ciguatoxin Detection in Flesh and Liver of Relevant Fish Species from the Canary Islands
(MDPI, 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 ...
DNA metabarcoding reveals differences in distribution patterns and ecological preferences among genetic variants within some key freshwater diatom species
(Elsevier, 2021-07-20)
Our study evaluates differences in the distribution and ecology of genetic variants within several ecologically important diatom species that are also key for Water Framework Directive monitoring of ...
Non-perennial segments in river networks
(Springer Nature, 2023-11-23)
Non-perennial river segments — those that recurrently cease to flow or frequently dry — occur in all river networks and are globally more abundant than perennial (always flowing) segments. However, ...
Genome-enabled phylogenetic and functional reconstruction of an araphid pennate diatom Plagiostriata sp. CCMP470, previously assigned as a radial centric diatom, and its bacterial commensal
(Springer Nature, 2020-06-10)
Diatoms are an ecologically fundamental and highly diverse group of algae, dominating marine primary production in both open-water and coastal communities. The diatoms include both centric species, which ...
Reviving Europe's rivers: Seven challenges in the implementation of the Nature Restoration Law to restore free-flowing rivers
(Wiley, 2024-01-30)
The EU Nature Restoration Law represents an important opportunity for freshwater habitat restoration and, consequently, freshwater biodiversity protection. However, a number of challenges must be ...
Gambierdiscus and Fukuyoa as potential indicators of ciguatera risk in the Balearic Islands
(Elsevier, 2020-10-22)
Gambierdiscus and Fukuyoa are genera of toxic dinoflagellates which were mainly considered as endemic to marine intertropical areas, and that are well known as producers of ciguatoxins (CTXs) and ...
Paleolimnological responses of Ecuadorian páramo lakes to local and regional stressors over the last two millennia
(Springer Nature, 2023-01-11)
Increasing surface air temperatures and human influences (e.g., agriculture, livestock grazing, tourism) are altering lacustrine ecosystems in the South American Andean páramo, and these influences are ...
