Sellaphora mayrii (Bacillariophyceae), a new diatom from the Argentinean Patagonia
(Magnolia Press, 2020-03-26)
A new species of Sellaphora was found in modern and fossil sediments from shallow-lake Laguna Gemelas Este, Santa Cruz, Argentina. The new taxon was studied with light microscopy and scanning electron ...
Planktic diatom responses to spatiotemporal environmental variation in high-mountain tropical lakes
(Wiley, 2024-01-18)
1. Tropical lakes harbour high levels of biodiversity, but the temporal and spatial variability of biological communities are still inadequately characterised, making it difficult to predict the impact ...
Use of anionic polymer-coated magnetic beads to pre-concentrate Ostreid Herpesvirus 1 from seawater: Application to a UV disinfection treatment
(Elsevier, 2021-02-02)
Ostreid Herpesvirus 1 (OsHV-1) represents a serious threat to shellfish aquaculture worldwide. To minimise its impact, early warning systems able to detect the virus in seawater prior to infection of ...
Diversity and regional distribution of harmful algal events along the Atlantic margin of Europe
(Elsevier, 2021-02-12)
The IOC-ICES-PICES Harmful Algal Event Database (HAEDAT) was used to describe the diversity and spatiotemporal distribution of harmful algal events along the Atlantic margin of Europe from 1987 - 2018. ...
Identification of New CTX Analogues in Fish from the Madeira and Selvagens Archipelagos by Neuro-2a CBA and LC-HRMS
(MDPI, 2022-03-29)
Ciguatera Poisoning (CP) is caused by consumption of fish or invertebrates contaminated with ciguatoxins (CTXs). Presently CP is a public concern in some temperate regions, such as Macaronesia (North-Eastern ...
Molecular identification, life cycle characterization, and hatchery seed production of dwarf oysters from the Ebro Delta (Spain)
(EDP Sciences, 2022-05-20)
Dwarf oysters in the Ebro Delta are only observed growing on local pen shells, Pinna nobilis L., currently under extinction risk. The species identification of these populations is uncertain, given ...
Multiple environmental benefits of alternate wetting and drying irrigation system with limited yield impact on European rice cultivation: The Ebre Delta case
(Elsevier, 2021-09-16)
The AWD is an irrigation technology for rice cultivation, consisting in implementing alternate draining and flooded periods over the growing season, that delivers multiple environmental benefits, such ...
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 ...
Retos y oportunidades para la evaluación del estado ecológico en ríos temporales
(Asociación Española de Ecología Terrestre, 2024-03-06)
Los ríos temporales (RTs) son ecosistemas fluviales en los que los efectos de las perturbaciones antrópicas se mezclan con los de la propia perturbación natural que impone la temporalidad del flujo. A ...
Human practices behind the aquatic and terrestrial ecological decoupling to climate change in the tropical Andes
(Elsevier, 2022-02-24)
Anthropogenic climate change and landscape alteration are two of the most important threats to the terrestrial and aquatic ecosystems of the tropical Americas, thus jeopardizing water and soil resources ...
