(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 ...
Foliar heavy metals and stable isotope (delta C-13, delta N-15) profiles as reliable urban pollution biomonitoring tools
(Elsevier, 2021-01)
Anthropogenic heavy metal pollution is an important health issue in urban areas, and therefore rapid and inexpensive monitoring in time and space is desirable. This study aimed (i) to assess the suitability of Tilia cordata ...
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, ...

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 ...
