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 ...
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 ...
Diat.barcode, an open-access curated barcode library for diatoms
(Nature Research, 2019-10-22)
Diatoms (Bacillariophyta) are ubiquitous microalgae which produce a siliceous exoskeleton and which make a major contribution to the productivity of oceans and freshwaters. They display a huge diversity, ...
Basin-scale land use impacts on world deltas: Human vs natural forcings
(Elsevier, 2018-12-14)
A new global database of 86 deltas and river basins was analyzed to investigate the relative importance of deforestation and land use changes versus natural forcings in determining long-term total delta ...
Detecting harmful algal blooms with isothermal molecular strategies
(Elsevier, 2019-08-06)
The use of isothermal nucleic acid amplification strategies to detect harmful algal blooms (HABs) is in its infancy. We describe recent advances in these systems and highlight the challenges for the ...
Bed load transport and incipient motion below a large gravel bed river bend
(Elsevier, 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 ...
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 ...
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 ...
