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 ...
A polyphasic approach to the study of the genus Nitzschia (Bacillariophyta): three new planktonic species from the Adriatic Sea
(Wiley, 2020-10-21)
The paraphyletic diatom genus Nitzschia comprises over 1000 morphologically distinct pennate taxa, known from the benthos and plankton of freshwater, brackish and marine environments. The principal ...
Normalized abundance spectra of fish community reflect hydro-peaking on a Mediterranean large river
(Elsevier, 2018-10-19)
The European Water Framework Directive requires the integration of body size characters as an important part of fish-based bioassessment tools for freshwaters ecological status determination. The study ...
Evaluation of the occurrence and fate of pesticides in a typical Mediterranean delta ecosystem (EBRO RIVER delta) and risk assessment for aquatic organisms
(Elsevier, 2020-10-14)
Delta ecosystems are areas of high ecologic and economic values, where wildlife commonly shares the territory with intensive agricultural activities, particularly, rice cultivation and seafood production. ...
First Evidence of the Presence of Anatoxin-A in Sea Figs Associated with Human Food Poisonings in France
(MDPI, 2020-05-29)
From January 2011 to March 2018, 26 patients aged from 20 to 80 years old reported being sick in France after eating sea figs of the genus Microcosmus. The patients had symptoms evoking a cerebellar ...
An Updated Review of Tetrodotoxin and Its Peculiarities
(MDPI, 2022-01-03)
Tetrodotoxin (TTX) is a crystalline, weakly basic, colorless organic substance and is one of the most potent marine toxins known. Although TTX was first isolated from pufferfish, it has been found in ...
Life history traits of Mediterranean brown trout (Salmo trutta complex) in Pyrenean headwater streams
(Springer, 2022-03-25)
The Mediterranean brown trout (Salmo trutta complex) is native to basins draining to the Western Mediterranean Sea, and natural populations are currently declining in abundance and distribution due to ...
Drought decreases incorporation of recent plant photosynthate into soil food webs regardless of their trophic complexity
(Wiley, 2019-07-13)
Theory suggests that more complex food webs promote stability and can buffer the effects of perturbations, such as drought, on soil organisms and ecosystem functions. Here, we tested experimentally how ...
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 ...
A fast magnetic bead-based colorimetric immunoassay for the detection of tetrodotoxins in shellfish
(Elsevier, 2020-04-05)
Tetrodotoxin (TTX) is a potent neurotoxin responsible for many food poisoning incidents and some fatalities. Although mainly associated with the consumption of pufferfish, in recent years, TTX has been ...
