The effects of local climate on the correlation between weather and seed production differ in two species with contrasting masting habit / Bogdziewicz, Michał (Department of Systematic Zoology, Faculty of Biology, Adam Mickiewicz University) ; Szymkowiak, Jakub (Population Ecology Lab, Faculty of Biology, Adam Mickiewicz University) ; Fernández Martínez, Marcos (Centre of Excellence PLECO (Plant and Ecosystems), Department of Biology, University of Antwerp) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
Many plant species present inter-annual cycles of seed production (mast seeding), with synchronized high seed production across populations in some years. Weather is believed to be centrally involved in triggering masting. [...]

Treelines are sensitive to environmental changes, but few studies provide a mechanistic approach to understand treeline dynamics based on field experiments. The aim of this study was to determine how changes in the abiotic and/or biotic conditions associated with global change affect the performance of tree seedlings (later saplings) at the treeline in a 10-year experiment.

Most studies of the northern hemisphere carbon cycle based on atmospheric CO2 concentration have focused on spring and autumn, but the climate change impact on summer carbon cycle remains unclear. Here we used atmospheric CO2 record from Point Barrow (Alaska) to show that summer CO2 drawdown between July and August, a proxy of summer carbon uptake, is significantly negatively correlated with terrestrial temperature north of 50°N interannually during 1979–2012.

Steel slag, a by-product of the steel industry, contains high amounts of active iron oxide and silica which can act as an oxidizing agent in agricultural soils. Biochar is a rich source of carbon, and the combined application of biochar and steel slag is assumed to have positive impacts on soil properties as well as plant growth, which are yet to be validated scientifically.

80% of Volatile Organic Compounds (VOCs) that are emitted every year to the atmosphere come from biogenic sources (BVOCs), where many different families are included, such as isoprenoids. The production and emission of those compounds is influenced by environmental variables such as light and temperature. [...]

206 p, 4.0 MB Large-scale assessment of the defoliation and demography of Spanish forests along climatic gradients / Coll Brunet, Marta ; Carnicer i Cols, Jofre, dir. (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep, dir. (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Pons, Xavier, dir. (Universitat Autònoma de Barcelona. Departament de Geografia)
El canvi climàtic està provocant un augment de les sequeres a l'hemisferi nord, provocant episodis de declivi forestal i contribuint a la reducció de l'eficiència dels boscos per fixar carboni. Hi ha una manca d'avaluacions a escala macroecològica de les respostes dels boscos davant els episodis de sequera, incloent processos tals com defoliació, mortalitat o les respostes de les xarxes tròfiques. [...]
Climate change is progressively increasing severe drought events in the Northern Hemisphere, causing regional tree die-off events and contributing to the global reduction of the carbon sink efficiency of forests. [...]

394 p, 5.6 MB Stoichiometric and metabolomic shifts of organisms under environmental changes / Rivas Ubach, Albert ; Peñuelas, Josep, dir. (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Sardans i Galobart, Jordi, dir. (Centre de Recerca Ecològica i Aplicacions Forestals)
L'estequiometria ecològica pretén explicar l'estil de vida dels organismes i l'estructura i funció dels ecosistemes en relació a les proporcions de C:N:P dels organismes i ecosistemes. Un dels paradigmes centrals de l'estequiometria ecològica és la "growth rate hypothesis" (GRH) que proposa que els organismes en fase de creixement han d'incrementar l'aportació de P al RNA per suplir l'elevada demanda de síntesi proteica necessària pel creixement. [...]
Ecological stoichiometry aims to explain the organism life style and the ecosystem structure and function in relation to the environment and organism C:N:P ratios. One of the central paradigms of ecological stoichiometry is the growth rate hypothesis (GRH) proposing that growing organisms must increase their allocation of P to RNA to meet the elevated demands for the synthesis of proteins required for growth.

La variabilitat de l'estequiometria elemental dels organismes a causa de l'ontogènia i dels canvis en les condicions ambientals està relacionada amb la variabilitat metabolòmica. Això és degut a que els elements operen majoritàriament com a parts de compostos moleculars. [...]
La variabilidad de la estequiometria elemental de los organismos debida a la ontogenia y a los cambios en las condiciones ambientales está relacionada con la variabilidad metabolómica. Esto se debe a que los elementos operan mayoritariamente como partes de compuestos moleculares. [...]
The elemental stoichiometry variability of organisms caused for ontogeny and the changes in environmental conditions is linked with metabonomics variability. This is due that elements operate as a piece of molecular components. [...]
