Providing carbon skeletons to sustain amide synthesis in roots underlines the suitability of Brachypodium distachyon for the study of ammonium stress in cereals
(Oxford University Press, 2019-05-10)
Plants mainly acquire N from the soil in the form of nitrate (NO3-) or ammonium (NH4+). Ammonium-based nutrition is gaining interest because it helps to avoid the environmental pollution associated with nitrate fertilization. ...
New metabolic and genetic factors associated with Arabidopsis thaliana response to ammonium stress.
(2019-06-14)
A pesar de que el amonio es una fuente de nitrógeno más respetuosa cuando es suministrada junto con inhibidores de la nitrificación con el medio ambiente que el nitrato, la gran mayoría de las plantas sufren estrés amoniacal ...
Public attitudes toward biodiversity‐friendly greenspace management in Europe
(Wiley, 2020)
Increasing urbanization worldwide calls for more sustainable urban development. Simultaneously, the global biodiversity crisis accentuates the need of fostering biodiversity within cities. Policies supporting urban nature ...
Isotopic labelling reveals the efficient adaptation of wheat root TCA cycle flux modes to match carbon demand under ammonium nutrition
(Nature Publishing Group, 2019-06-20)
Proper carbon (C) supply is essential for nitrogen (N) assimilation especially when plants are grown under ammonium (NH4+) nutrition. However, how C and N metabolic fluxes adapt to achieve so remains uncertain. In this ...
Relationship between salt use in fish farms and driftof macroinvertebrates in a freshwater stream
(Inter Research, 2020)
In Chile, salt (NaCl) use per salmon fish farm ranges between 20-30 t yr(-1) and is used to prevent and control fungal infections. An increase in salinity in freshwater can have adverse effects on freshwater biodiversity ...
Brachyodium distachyon as a model for defining the basis of adaptation to ammonium nutrition in grasses
(2019-10-25)
El nitrógeno es un nutriente esencial para las plantas y decisivo para la productividad de los cultivos. La fertilización intensiva, principalmente en forma nítrica, tiene un impacto negativo en el medioambiente, debido ...
Soil nitrogen dynamics during an oilseed rape (Brassica napus L.) growing cycle in a humid Mediterranean climate
(Nature Publishing, 2019-09-25)
Nitrogen budgets help explain the supply pattern of N from the soil to the crop. Through budgeting, an improvement of the N fertilization strategy can be achieved. The objective of the present study, which was carried out ...
Spatial distribution of freshwater crustaceans in Antarctic and Subantarctic lakes
(Nature, 2019-05-28)
Antarctic and Subantarctic lakes are unique ecosystems with relatively simple food webs, which are likely to be strongly affected by climate warming. While Antarctic freshwater invertebrates are adapted to extreme environmental ...
Genotyping-by-sequencing resolves relationships in Polygonaceae tribe Eriogoneae
(Wiley, 2021-08)
The resolution of cryptic diversity is essential for understanding the evolutionary diversification of lineages and establishing conservation priorities. We examine relationships in Eriogoneae (Polygonaceae), a diverse ...
Functional repercussions of riparian biodivesity loss in streams. Multifunctionality, diversity metrics and underlying mechanisms.
(2020-12-02)
El objetivo de esta tesis es abordar cuestiones clave poco exploradas en la investigación de la relación entre la biodiversidad y el funcionamiento de los ecosistemas (BEF, por sus siglas en inglés). Concretamente se estudia ...
