Widespread population declines have been reported for diverse Mediterranean butterflies over the last three decades, and have been significantly associated with increased global change impacts. The specific landscape and climatic drivers of these declines remain uncertain for most declining species. [...]

Life and the five biological laws. Lessons for global change models and sustainability / Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals) ; Baldocchi, Dennis (University of California at Berkeley. Department of Environmental Science)
Life on Earth is the result of a continuous accumulation of information by combination and innovation using endo- (inside the organism) and exosomatic (outside the organism) energy. Sustenance occurs through cycles of life and death. [...]

Measuring in situ soil fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) continuously at high frequency requires appropriate technology. We tested the combination of a commercial automated soil CO2 flux chamber system (LI-8100A) with a CH4 and N2O analyzer (Picarro G2308) in a tropical rainforest for 4 months. [...]

The increasing success of invasive plant species in wetland areas can threaten their capacity to store carbon, nitrogen, and phosphorus (C, N, and P). Here, we have investigated the relationships between the different stocks of soil organic carbon (SOC), and total C, N, and P pools in the plant–soil system from eight different wetland areas across the South‐East coast of China, where the invasive tallgrass Spartina alterniflora has replaced the native tall grasses Phragmites australis and the mangrove communities, originally dominated by the native species Kandelia obovata and Avicennia marina.

Soil pH is commonly considered a dominant factor affecting the function of microbiota. Few studies, however, have focused on communities of bacteria able to solubilize inorganic phosphate (iPSB), which are important for the mobilization of soil phosphorus (P), because finding an effective method to assess the abundance and diversity of iPSB communities is difficult.

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. [...]

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. [...]
