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 ...
Side-Effects of Domestication: Cultivated Legume Seeds Contain Similar Tocopherols and Fatty Acids but Less Carotenoids than Their Wild Counterparts
(Biomed Central, 2014-12-20)
BACKGROUND: Lipophilic antioxidants play dual key roles in edible seeds (i) as preservatives of cell integrity and seed viability by preventing the oxidation of fats, and (ii) as essential nutrients for human and animal ...
Modified atmosphere packaging and dark/light refrigerated storage in green leafy vegetables have impact on nutritional value
(Springer, 2019-01-04)
The consumption of zeaxanthin (Z) through a vegetable-rich diet is recommended to reduce the progression of age-related macular degeneration. Due to Z’s intrinsic dynamic character that results from its participation in ...
Biodiversity patterns in the managed and unmanaged silver fir-beech forests in the western Pyrenees: towards sustainable use.
(2018-04-20)
La explotación forestal está incrementándose en todo el mundo, siendo bien conocido su impacto negativo en la biodiversidad. El concepto de "gestión forestal sostenible" ha irrumpido con fuerza en la silvicultura moderna ...
Unravelling metabolic mechanisms behind chloroplast desiccation tolerance: chlorophyllous fern spore as a new promising unicellular model
(Elsevier, 2018-11-22)
Fern spores are unicellular structures produced by the sporophyte generation that give rise to the haploid gametophyte. When released from the sporangium, spores are desiccation tolerant (DT) in the royal fern (Osmunda ...
