The role of forest maturity in extreme hydrological events
(Wiley, 2018-02-10)
This study aims to clarify the influence of forests, as well as other prevalent land cover types, on extreme hydrological events through a land cover gradient design. We selected 10 catchments within a ...
Avoiding quantification bias in metabarcoding: Application of a cell biovolume correction factor in diatom molecular biomonitoring
(Wiley, 2017-12-26)
In recent years, remarkable progress has been made in developing environmental DNA metabarcoding. However, its ability to quantify species relative abundance remains uncertain, limiting its application ...
Colorimetric DNA-based assay for the specific detection and quantification of Ostreopsis cf. ovata and Ostreopsis cf. siamensis in the marine environment
(Elsevier, 2019-03-16)
Ostreopsis is a toxic benthic dinoflagellate largely distributed worldwide in tropical and temperate areas. In the Mediterranean Sea, periodic summer blooms have been reported and have become a serious ...
Marine Dinoflagellate Assemblage in the Galápagos Marine Reserve
(Frontiers Media, 2019-05-07)
It is likely that harmful algal blooms have increased in frequency, intensity, and geographic distribution in the last decades in response to anthropogenic activities. The Galápagos Islands are renowned ...
Salinity as the main factor structuring small-bodied fish assemblages in hydrologically altered Mediterranean coastal lagoons
(Consejo Superior de Investigaciones Científicas, 2013-02-26)
In the Ebro Delta coastal lagoons, one of the main anthropogenic pressures is the artificial freshwater input. Each coastal lagoon has different water management schemes causing profound changes in its ...
Detection of azaspiracids in mussels using electrochemical immunosensors for fast screening in monitoring programs
(Elsevier, 2018-02-06)
Given the widespread occurrence of azaspiracids (AZAs), it is clearly necessary to advance in simple and low-cost methods for the rapid detection of these marine toxins in order to protect seafood ...
Bioaccessibility of lipophilic and hydrophilic marine biotoxins in seafood: An in vitro digestion approach
(Elsevier, 2019-04-28)
This study aimed to assess the bioaccessibility of different marine biotoxins in naturally contaminated shellfish and fish gonads using an in vitro digestion methodology. In general, hydrophilic toxins ...
Discovery of a kleptoplastic 'dinotom' dinoflagellate and the unique nuclear dynamics of converting kleptoplastids to permanent plastids
(Nature Research, 2019-07-19)
A monophyletic group of dinoflagellates, called ‘dinotoms’, are known to possess evolutionarily intermediate plastids derived from diatoms. The diatoms maintain their nuclei, mitochondria, and the ...
Herbivore control in connected seascapes: habitat determines when population regulation occurs in the life history of a key herbivore
(Wiley, 2018-02-08)
Herbivore outbreaks often trigger catastrophic overgrazing events in marine macrophyte ecosystems. The sea urchin Paracentrotus lividus, the dominant herbivore of shallow Mediterranean seascapes, is ...
Effects of water pollution and river fragmentation on population genetic structure of invasive mosquitofish
(Elsevier, 2018-05-22)
We analyzed variation at the GPI-2 locus and eleven microsatellite loci of eastern mosquitofish Gambusia holbrooki populations introduced to the Ebro River (Spain), sampling above and below a dam (Flix ...
