Institute of Agricultural Resources and Regional Planning) ; Han, Xingguo (Chinese Academy of Sciences. Institute of Applied Ecology)
Both the dominance and the mass ratio hypotheses predict that plant internal nutrient cycling in ecosystems is determined by the dominant species within plant communities. We tested this hypothesis under conditions of extreme drought by assessing plant nutrient (N, P and K) uptake and resorption in response to experimentally imposed precipitation reductions in two semiarid grasslands of northern China.

Servei de Ressonància Magnètica Nuclear) ; Lloret Maya, Francisco (Centre de Recerca Ecològica i d'Aplicacions Forestals)
The aim of this study was to understand how drought-induced tree mortality and subsequent secondary succession would affect soil bacterial taxonomic composition as well as soil organic matter (SOM) quantity and quality in a mixed Mediterranean forest where the Scots pine (Pinus sylvestris) population, affected by climatic drought-induced die-off, is being replaced by Holm-oaks (HO; Quercus ilex).

10 p, 1.4 MB The role of microarthropods in emerging models of soil organic matter / Soong, Jennifer L. (University of Antwerp. Department of Biology) ; Nielsen, Uffe N. (University of Western Sydney, Hawkesbury. Institute for the Environment)
A new understanding of soil organic matter (SOM) formation and stabilization has emerged over the past decade, highlighting the importance of microbial activity, mineral association of organic matter and aggregate occlusion of organic matter to SOM persistence. [...]

Department of Earth and Ocean Sciences) ; Brandes, Jay (Skidaway Institute of Oceanography) ; McNulty, Ian (Argonne National Laboratory) ; Vine, David J. (Argonne National Laboratory)
Biological productivity in many ocean regions is controlled by the availability of the nutrient phosphorus. In the Mediterranean Sea, aerosol deposition is a key source of phosphorus and understanding its composition is critical for determining its potential bioavailability. [...]

Effects of fire on stream water chemistry in heathland watersheds. Conductivity, PH. and concentrations of Nat. K + , Ca2+ and Mg2+ were monitored for up to two years in baseflow water of four streams draining burned and unburned watersheds in Calluna-dominated dry heathlands in Montseny (Barcelona, N E Spain). [...]
Se midieron la conductividad. el p H y las concentraciones de N a f , K + , Ca2+ y Mg'+ durante dos años en el caudal de base de cuatro arroyos que drenan landas de Calluna quemadas y no quemadas en La Calma (Montseny, Barcelona). [...]
