The metabolic regimes of 356 rivers in the United States
(Nature Publishing, 2018-12-11)
A national-scale quantification of metabolic energy flow in streams and rivers can improve understanding of the temporal dynamics of in-stream activity, links between energy cycling and ecosystem services, and the effects ...
Ecosystem services assessment in Urdaibai Biosphere Reserve social-ecological system: Insights into management strategies
(2018-12-18)
Tesi hau Urdaibaiko Biosfera Erreserbako sistema sozial-ekologikoaren ekosistemen zerbitzuen ebaluazio eta balorazioan zentratzen da, beti ere paisaiaren antolamendu eta kudeaketa iraunkorrerako erabaki-hartze prozesuan ...
Adaptative mechanisms of cereals to climate change: the importance of nitrogen sources in soils.
(2018-04-27)
La actividad humana y más concretamente, la industria, la agricultura, el consumo de combustibles fósiles, la deforestación, la quema de restos vegetales y la ganadería han provocado un rápido aumento de gases de efecto ...
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, ...
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 ...
First evidence of freezing tolerance in a resurrection plant: insights into molecular mobility and zeaxanthin synthesis in the dark
(Wiley, 2018-01-18)
The photoprotective mechanisms of desiccation tolerance and freezing toler- ance and their relation to molecular mobility (cell vitrification) were assessed in a single model: the exceptional subalpine and resurrection ...
Can Parietin Transfer Energy Radiatively to Photosynthetic Pigments?
(MDPI, 2018-07)
The main role of lichen anthraquinones is in protection against biotic and abiotic stresses, such as UV radiation. These compounds are frequently deposited as crystals outside the fungal hyphae and most of them emit visible ...
A field portable method for the semi-quantitative estimation of dehydration tolerance of photosynthetic tissues across distantly related land plants.
(2018-12-04)
Desiccation tolerant (DT) plants withstand complete cellular dehydration (reaching relative
water contents below 30% in their photosynthetic tissues), while desiccation sensitive (DS)
plants exhibit different degrees of ...
Effectiveness And Ecotoxicity Of Zero-Valent Iron Nanoparticles During Rhizoremediation Of Soil Contaminated With Zn, Cu, Cd And Diesel
(Elsevier, 2018-04)
The remediation of soils simultaneously contaminated with organic and inorganic compounds is still a challenging task. The application of metallic nanoparticles, such as zero-valent iron nanoparticles (nZVI), for soil ...
