Biotic vs. Abiotic Control of Decomposition: A Comparison of the Effects of Simulated Extinctions and Changes in Temperature
(Public Library of Science, 2014-01)
The loss of species is known to have significant effects on ecosystem functioning, but only recently has it been recognized that species loss might rival the effects of other forms of environmental change on ecosystem ...
Abundance, composition, distribution and fate of floating marine litter in the south-east Bay of Biscay
(2022-07-19)
This PhD thesis presents a first overview of floating marine litter pollution in the south-east Bay of Biscay through a combination of harmonized observations, sampling methods, and numerical modelling techniques. Abundance ...
Distance decay 2.0 – A global synthesis of taxonomic and functional turnover in ecological communities
(Wiley, 2022-07)
Aim: Understanding the variation in community composition and species abundances (i.e., beta-diversity) is at the heart of community ecology. A common approach to examine beta-diversity is to evaluate directional variation ...
Depletion of the heaviest stable N isotope is associated with NH4 +/NH3 toxicity in NH4 +-fed plants
(BioMed Central, 2011-05-16)
Background: In plants, nitrate (NO(3)(-)) nutrition gives rise to a natural N isotopic signature (delta(15)N), which correlates with the delta(15)N of the N source. However, little is known about the relationship between ...
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 ...
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 ...
Nitrogen Source and External Medium pH Interaction Differentially Affects Root and Shoot Metabolism in Arabidopsis
(Frontiers Media, 2016-02-01)
Ammonium nutrition often represents an important growth-limiting stress in plants. Some of the symptoms that plants present under ammonium nutrition have been associated with pH deregulation, in fact external medium pH ...
Microbial indicators for the assessment of the impact of metal contamination and phytoremediation of soil health
(2017-03-17)
El suelo es un sistema dinámico y complejo, cuyas funciones son de gran importancia para la sostenibilidad de los ecosistemas terrestres y nuestra propia supervivencia. Por desgracia, la contaminación de suelos con metales ...
Turning waste into value: Production of the high-value compounds poly(3-hydroxybutyrate) and lactic acid from renewable feedstocks based on municipal solid waste
(2020-12-22)
El modelo de sociedad actual y el aumento de las ciudades, esta generando un incremento de la generación de residuos sólidos municipales. Este hecho ha puesto de relieve un problema que no solo afecta la parte medioambiental, ...
