Community Turnover of Wood-Inhabiting Fungi across Hierarchical Spatial Scales
(Public Library Science, 2014-07-24)
For efficient use of conservation resources it is important to determine how species diversity changes across spatial scales. In many poorly known species groups little is known about at which spatial scales the conservation ...
Plastidic Phosphoglucose Isomerase Is an Important Determinant of Starch Accumulation in Mesophyll Cells, Growth, Photosynthetic Capacity, and Biosynthesis of Plastidic Cytokinins in Arabidopsis
(Public Library of Science, 2015-03-26)
Phosphoglucose isomerase (PGI) catalyzes the reversible isomerization of glucose-6-phosphate and fructose-6-phosphate. It is involved in glycolysis and in the regeneration of glucose-6-P molecules in the oxidative pentose ...

[ES]En la presente tesis se ha estudiado el impacto de diferentes fertilizantes y pesticidas utilizados en la Zona Vulnerable de Vitoria-Gasteiz en la calidad del suelo y las aguas de dicha zona. Se ha podido constatar que ...
Global pressures, specific responses: effects of nutrient enrichment in streams from different biomes
(IOP PUBLISHING LTD, 2013-01-09)
We assessed the effects of nutrient enrichment on three stream ecosystems running through distinct biomes (Mediterranean, Pampean and Andean). We increased the concentrations of N and P in the stream water 1.6–4-fold ...
Evaluation of marine phytoplankton toxicity by application of marine invertebrate bioassays
(Instituto de Ciencias del Mar, 2014-06)
The dinoflagellate Alexandrium minutum and the haptophyte Prymnesium parvum are well known for their toxin production and negative effects in marine coastal environments. A. minutum produces toxins which cause paralytic ...
Ecodiseño de alimentos mediante análisis de ciclo de vida
(2015-12-17)
La creciente demanda de producción de alimentos debida al aumento de la población mundial, ejerce una gran presión sobre los ecosistemas y el medio ambiente del planeta. Los alimentos, a lo largo de su ciclo de vida utilizan ...
Uncovering Ecosystem Service Bundles through Social Preferences
(Public Library of Science, 2012-06-18)
Ecosystem service assessments have increasingly been used to support environmental management policies, mainly based on biophysical and economic indicators. However, few studies have coped with the social-cultural dimension ...
