Study of phytoplankton as food resource and toxicity risk for human health in offshore bivalve aquaculture in the Basque Country
(2018-06-15)
El fitoplancton, como base de las redes tróficas marinas, es la principal fuente de energía para los bivalvos filtradores, entre otros. En el País Vasco, el reciente interés en el cultivo de bivalvos en aguas costeras llevó ...
Rapid colour changes in Euglena sanguinea (Euglenophyceae) caused by internal lipid globule migration
(Taylor & Francis, 2018-11-23)
The accumulation of red pigments under chronic stress is a response observed in most
groups of oxygenic photoautotrophs. It is thought that the red pigments in the cell shield
the chlorophyll located underneath from the ...
El mirlo acuático Cinclus cinclus L., 1758 en Gipuzkoa: distribución y parámetros demográficos.
(2018-03-27)
El mirlo acuático es un paseriforme que reúne las condiciones para ser un buen indicador de las perturbaciones de los ecosistemas acuáticos. Su presencia, ausencia o abundancia indica la extensión de la perturbación o ...
Testing Wastewater Treatment Plant Effluent Effects on Microbial and Detritivore Performance: a Combined Field and Laboratory Experiment
(Elsevier, 2018-10)
The amount of pollutants and nutrients entering rivers via point sources is increasing along with human population and activity. Although wastewater treatment plants (WWTPs) greatly reduce pollutant loads into the environment, ...
15N Natural Abundance Evidences a Better Use of N Sources by Late Nitrogen Application in Bread Wheat
(Frontiers Media, 2018-06-22)
This work explores whether the natural abundance of N isotopes technique could be used to understand the movement of N within the plant during vegetative and grain filling phases in wheat crop (Triticum aestivum L) under ...
On the spatial and temporal variations of zooplankton in Northeast Atlantic shelf waters
(2018-12-18)
In the present study we have used zooplankton time-series, for the 1999 ¿ 2013 period, coming from long-term monitoring programs carried out at four sites placed along a latitudinal gradient within the Northeast Atlantic ...
Determining diet from faeces: Selection of metabarcoding primers for the insectivore Pyrenean desman ( Galemys pyrenaicus )
(Public Library Science, 2018-12-14)
Molecular techniques allow non-invasive dietary studies from faeces, providing an invaluable tool to unveil ecological requirements of endangered or elusive species. They contribute to progress on important issues such as ...
Priming of leaf litter decomposition by algae seems of minor importance in natural streams during autumn
(Public Library Science, 2018-09-07)
Allochthonous detritus of terrestrial origin is one of the main energy sources in forested headwater streams, but its poor nutritional quality makes it difficult to use by heterotrophs. It has been suggested that algae ...
Drying and Rainfall Shape the Structure and Functioning of Nitrifying Microbial Communities in Riverbed Sediments
(Frontiers Media, 2018-11-16)
Non-flow periods in fluvial ecosystems are a global phenomenon. Streambed drying and rewetting by sporadic rainfalls could drive considerable changes in the microbial communities that govern stream nitrogen (N) availability ...
Understanding the effects of predictability, duration, and spatial pattern of drying on benthic invertebrate assemblages in two contrasting intermittent streams
(Public Library Science, 2018-03-28)
In the present study, we examined the effects of different drying conditions on the composition, structure and function of benthic invertebrate assemblages. We approached this objective by comparing invertebrate assemblages ...
