The eddy-covariance (EC) micro-meteorological technique and the ecology-based biometric methods (BM) are the primary methodologies to quantify CO₂ exchange between terrestrial ecosystems and the atmosphere (net ecosystem production, NEP) and its two components, ecosystem respiration and gross primary production.

Northern Research Station) ; Noormets, Asko (North Carolina State University. Departament of Forestry and Environmental Resources) ; Peñuelas, Josep. (Centre de Recerca Ecològica i Aplicacions Forestals)
In evergreen conifers, where the foliage amount changes little with season, accurate detection of the underlying “photosynthetic phenology” from satellite remote sensing has been difficult, presenting challenges for global models of ecosystem carbon uptake. [...]

Department of Environmental Science and Studies) ; Seco, Roger (University of California, Irvine. Department of Earth System Science)
Stress-induced emissions of biogenic volatile organic compounds (VOCs) from terrestrial eco- systems may be one of the dominant sources of VOC emissions worldwide. Understanding the ecosystem stress response could reveal how ecosystems will respond and adapt to climate change and, in turn, quan- tify changes in the atmospheric burden of VOC oxidants and secondary organic aerosols.

Rhizodeposition under drought and consequences for soil communities and ecosystem resilience / Preece, Catherien (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Background: Rhizodeposition is the release of organic compounds from plant roots into soil. Positive relationships between rhizodeposition and soil microbial biomass are commonly observed. Rhizodeposition may be disrupted by increasing drought however the effects of water stress on this process are not sufficiently understood. [...]

Topsoil depth substantially influences the responses to drought of the foliar metabolomes of Mediterranean forests / Rivas Ubach, Albert (Centre de Recerca Ecològica i Aplicacions Forestals) ; Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Guenther, A.

Centrum výzkumu globální změny) ; Urban, Otmar (Akademie věd České Republiky. Centrum výzkumu globální změny) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
The upper soil provides support, water, and nutrients to terrestrial plants and is therefore crucial for forest dynamics. We hypothesised that a tree's metabolic activity (and therefore its metabolome; the total set of metabolites) would be affected by both the depth of upper soil layers and water availability. [...]

4 p, 83.4 KB Reintroduint la marmota alpina als Pirineus / Ferrandiz Rovira, Mariona (Centre de Recerca Ecològica i Aplicacions Forestals)
Malgrat la manca de planificació i de seguiment, la reintroducció de la marmota alpina als Pirienus ha estat un èxit. Tot i així, les poblacions reintroduïdes a Andorra, la Cerdanya i el Ripollès tenen molt poca diversitat genètica, un aspecte crucial per adaptar-se al nou ambient. [...]

L'activitat humana ha provocat un augment de les emissions de compostos de nitrogen. L'ús de col·lectors de pluja basats en resines permetrà un mostreig de la deposició de nitrogen més espaiat en el temps que amb els col·lectors convencionals. [...]

33 p, 5.0 MB Affecting factors and recent improvements of the photochemical reflectance index (PRI) for remotely sensing foliar, canopy and ecosystemic radiation-use efficiencies / Zhang, Chao (Centre de Recerca Ecològica i Aplicacions Forestals) ; Filella Cubells, Iolanda (Centre de Recerca Ecològica i Aplicacions Forestals) ; Garbulsky, Martín Fabio (University of Buenos Aires. Facultad de Agronomía) ; Peñuelas, Josep. (Centre de Recerca Ecològica i Aplicacions Forestals)
Accurately assessing terrestrial gross primary productivity (GPP) is crucial for characterizing the climate-carbon cycle. Remotely sensing the photochemical reflectance index (PRI) across vegetation functional types and spatiotemporal scales has received increasing attention for monitoring photosynthetic performance and simulating GPP over the last two decades.

Cloud forests harbor high levels of orchid diversity. However, due to the high fragmentation of these forests in the Andes, combined with the pressure for new agricultural land, orchid diversity is highly threatened. [...]

16 p, 1.4 MB Dynamics of non-structural carbohydrates in three Mediterranean woody species following long-term experimental drought / Rosas Torrent, Teresa (Centre de Recerca Ecològica i Aplicacions Forestals) ; Galiano Pérez, Lucía (Centre de Recerca Ecològica i Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals) ; Martínez Vilalta, Jordi, 1975- (Centre de Recerca Ecològica i Aplicacions Forestals)
Stored non-structural carbohydrates (NSC) have been proposed as a key determinant of drought resistance in plants. However, the evidence for this role is controversial, as it comes mostly from observational, short-term studies. [...]
