Linking fish-based biological indicators with hydrological dynamics in a Mediterranean river: Relevance for environmental flow regimes
(Ecological Indicators, 2018-08-07)
The relationship between flow dynamics and biological communities becomes especially relevant in Mediterranean rivers. Given their natural variability and growing anthropogenic pressures, their low ...
Seagrass epiphytic assemblages are strong indicators of agricultural discharge but weak indicators of host features
(Estuarine, Coastal and Shelf Science, 2018-03-02)
Wastewater pulses from rice agriculture are persistently discharged into the northern shore of the Alfacs Bay (Ebro Delta, NW Mediterranean) from April to November. The bay also receives water from ...
Herbivore control in connected seascapes: habitat determines when population regulation occurs in the life history of a key herbivore
(Oikos, 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 ...
Occurrence of cyclic imines in European commercial seafood and consumers risk assessment
(Environmental Research, 2017-12-01)
Cyclic imines constitute a quite recently discovered group of marine biotoxins that act on neural receptors and that bioaccumulate in seafood. They are grouped together due to the imino group functioning ...
Dependence of sediment sorting on bedload transport phase in a river meander
(Earth Surface Processes and Landforms, 2018-03-05)
It is widely recognized nowadays that there are at least two different phases of bedload sediment transport in gravel‐bed rivers. However, the transition between these phases is still poorly or subjectively ...
The role of forest maturity in extreme hydrological events
(Ecohydrology, 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 ...
Adult spawning and early larval development of the endangered bivalve Pinna nobilis
(Aquaculture, 2017-10-16)
The development of aquaculture activities has posed an alternative solution for the preservation of some overexploited shellfish fisheries worldwide. In the same way, endemic Mediterranean bivalves such ...
Bed load transport and incipient motion below a large gravel bed river bend
(Advances in Water Resources, 2017-08-08)
A new data set of bed load measurements in a cross-section at the exit of a river bend is presented. Data are analyzed to identify processes that contribute to the morphodynamic stability of gravel bed ...
Avoiding quantification bias in metabarcoding: Application of a cell biovolume correction factor in diatom molecular biomonitoring
(Methods in Ecology and Evolution, 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 ...
Rapid screening and multi-toxin profile confirmation of tetrodotoxins and analogues in human body fluids derived from a puffer fish poisoning incident in New Caledonia
(Food and Chemical Toxicology, 2017-12-30)
In August 2014, a puffer fish poisoning incidence resulting in one fatality was reported in New Caledonia. Although tetrodotoxin (TTX) intoxication was established from the patients' signs and symptoms, ...
