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 ...
Effects of urban pollution on stream ecosystem functioning
(2019-07-23)
Azken mendean zehar gizakiek aurrekaririk gabeko populazioaren tamainaren hazkuntza, baliabideen erabilera eta garapen ekonomikoa eragin dituzte; hiri- eta herri-guneetan sortutako kutsadura mundu osoko ibai eta errekei ...
Effects of water abstraction on stream ecosystem functioning
(2015-12-14)
Ur-detrakzioa mundu osoan zehar oso hedatuta dagoen jarduera da, handitzen jarraitzenduen ur-, jaki- eta energia-eskariari erantzuteko etorkizunean gehiago areagotzea esperodena. Ur-detrakzioak tarteko emari txikitzeak ...
Effects Of Human-Driven Water Stress on River Ecosystems: a Meta-Analysis
(Nature Publishing Group, 2018-07-30)
Human appropriation of water resources may induce water stress in freshwater ecosystems when ecosystem needs are not met. Intensive abstraction and regulation cause river ecosystems to shift towards non-natural flow regimes, ...
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 ...
Effects of global change on the functioning of Mediterranean Rivers
(2015-07-29)
Esta tesis explora los efectos del cambio global en el funcionamiento de losecosistemas de ríos mediterráneos, que se ven severamente impactados por lasactividades de los humanos. Para tener una perspectiva espacial amplia, ...
Plant invasion in Cantabrian rivers: drivers and effects on plant diversity and riparian habitats
(2017-01-17)
La presente tesis aborda diferentes aspectos de la invasión por plantas alóctonas en ríos de la vertiente cantábrica del norte de España. Se determinaron qué factores, tanto de tipo ambiental como antrópico, están relacionados ...
Photosynthetic responses of trees in high-elevation forests: comparing evergreen species along an elevation gradient in the Central Andes
(Oxford University Press, 2015)
Plant growth at extremely high elevations is constrained by high daily thermal amplitude, strong solar radiation and water scarcity. These conditions are particularly harsh in the tropics, where the highest elevation ...
