A rapid cleaning method for diatoms
(Taylor & Francis, 2019-07-18)
We describe here a protocol for cleaning diatoms when time is short and the amount of
sample is very limited. Essentially, the method consists of drying material onto coverslips and
cleaning it directly ...
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 ...
Community structure of benthic macroinvertebrates inhabiting a highly stratified Mediterranean estuary
(Consejo Superior de Investigaciones Científicas, 2011-09-30)
The community composition and spatial distribution of benthic macroinvertebrates were studied along the
Ebro estuary, a highly stratified estuary located in the NE Iberian Peninsula. During the last ...
The future of biotic indices in the ecogenomic era: Integrating (e)DNA metabarcoding in biological assessment of aquatic ecosystems
(Elsevier, 2018-05-22)
The bioassessment of aquatic ecosystems is currently based on various biotic indices that use the occurrence and/or abundance of selected taxonomic groups to define ecological status. These conventional ...
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 ...
Adaptation of the European Fish Index (EFI+) to Include the Alien Fish Pressure
(MDPI, 2023-12-29)
The European Fish Index EFI+ is the only fish-based multimetric index for the assessment of the ecological status of running waters that is validated and thus applicable across most countries of the ...
Ciguatoxin-like toxicity distribution in flesh of amberjack (Seriola spp.) and dusky grouper (Epinephelus marginatus)
(Elsevier, 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 ...
Inheritance of spheroid body and plastid in the raphid diatom Epithemia (Bacillariophyta) during sexual reproduction
(Taylor and Francis, 2021-04-21)
Diatoms belonging to the family Epithemiaceae have endosymbiont ‘spheroid bodies’, which have received attention as a model to provide new insights into the early stages of organelle evolution. Uniparental ...
Nitzschia fenestralis: A new diatom species abundant in the Holocene sediments of an eastern African crater lake
(Czech Phycological Society, 2020-02-18)
Nitzschia is common in the phytoplankton of several East African lakes. A new species, Nitzschia fenestralis, sp. nov. D. Grady, D.G. Mann et Trobajo was encountered at numerous depths in a 16 m sediment ...
