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 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, ...
Different Sets of Traits Explain Abundance and Distribution Patterns of European Plants at Different Spatial Scales
(Wiley, 2021-03-11)
Aim Plant functional traits summarize the main variability in plant form and function across taxa and biomes. We assess whether geographic range size, climatic niche size, and local abundance of plants can be predicted by ...

Embriogénesis somática de Pinus spp. bajo condiciones de estrés abiótico: modelo para el estudio de los mecanismos que controlan la tolerancia
(2022-07-06)
Water, the most abundant molecule in our planet, is truly and empirically accepted as an essential component to sustain life on Earth. The extraordinary properties of this unique and universal "matrix of life" have served ...
The Temperate Deciduous Forests of the Northern Hemisphere. A review
(Universidad Complutense de Madrid, 2022)
Temperate Deciduous Forests occur almost exclusively in the northern hemisphere and thrive under temperate climate with cold winter and warm-humid summer. They covered a continuous belt during most of the Tertiary across ...

(2008-09-23)
En la última década se ha difundido el concepto de “servicios ambientales” y la importancia de su conservación para mantener el bienestar de la sociedad; así mismo, se ha subrayado necesidad de identificar indicadores de ...
Activation of violaxanthin cycle in darkness is a common response to different abiotic stresses : a case study in Pelvetia canaliculata
(BioMed Central, 2011-12-26)
Background: In the violaxanthin (V) cycle, V is de-epoxidized to zeaxanthin (Z) when strong light or light combined with other stressors lead to an overexcitation of photosystems. However, plants can also suffer stress in ...
