10 p, 1.4 MB Social dynamics within decomposer communities lead to nitrogen retention and organic matter build-up in soils / Kaiser, Christina (Universität Wien. Institut für Mikrobiologie und Ökosystemwissenschaften) ; Franklin, Oskar (International Institute for Applied Systems Analysis) ; Richter, Andreas (Universität Wien. Institut für Mikrobiologie und Ecosystem Wissenschaft) ; Dieckmann, Ulf (International Institute for Applied Systems Analysis)
The chemical structure of organic matter has been shown to be only marginally important for its decomposability by microorganisms. The question of why organic matter does accumulate in the face of powerful microbial degraders is thus key for understanding terrestrial carbon and nitrogen cycling. [...]

Large-scale climate patterns control variability in the global carbon sink. In Europe, the North-Atlantic Oscillation (NAO) influences vegetation activity, however the East-Atlantic (EA) pattern is known to modulate NAO strength and location. [...]

Recent warming significantly advanced leaf onset in the northern hemisphere. This signal cannot be accurately reproduced by current models parameterized by daily mean temperature (Tmean). Here using in situ observations of leaf unfolding dates (LUDs) in Europe and the United States, we show that the interannual anomalies of LUD during 1982–2011 are triggered by daytime (Tmax) more than by nighttime temperature (Tmin).

Human domination of the biosphere includes changes to disturbance regimes, which push many ecosystems towards early-successional states. Ecological theory predicts that early-successional ecosystems are more sensitive to perturbations than mature systems, but little evidence supports this relationship for the perturbation of climate change.

16 p, 1.6 MB Complejidad y arquitectura de redes sostenibles entre la biosfera y la tecnoosfera : de internet a gaia / Ayestarán, Ignacio (Universidad del País Vasco. Departamento de Filosofía)
Focusing on a global world, we should seek to understand the architecture of sustainable networks between the (real) biosphere and the (virtual) technoosphere, from the World Wide Web to the global ecology, from the Internet to Gaia in a symbiotic planet, where the Earth is a global brain/mind.
Desde un mundo global, deberíamos perseguir la comprensión de la arquitectura de redes sostenibles entre la biosfera (real) y la tecnoosfera (virtual), desde la World Wide Web hasta la ecología global, desde Internet a Gaia en un planeta simbiótico, donde la Tierra es un cerebro o mente global.
