Dear colleagues, we invite you to submit an abstract for the session "Global climate change effects on carbon, water and nutrient dynamics in the rhizosphere" at the annual meeting of the Ecological Society of Germany, Austria and Switzerland (GfÖ) to be held in Potsdam (close to Berlin), Germany, on September 9-13, 2013. The session aims at bringing together scientists from multiple disciplines which use both experimental and modeling approaches to investigate root zone and hyphosphere processes. A more detailed description of the session can be found below.
**Registration is now available** and submissions for oral presentations and posters are called for. The deadline for submitting titles for presentations is April 30, 2013. http://www.gfoe-2013.de/index.php?cat=registration http://www.gfoe-2013.de/index.php?cat=callforpapers We are looking forward to meeting you in Potsdam! Best regards, Ina Meier, Marie Spohn and Andrea Carminati *************************************** Goal of the session Increasing duration and intensity of summer droughts as predicted by global climate change models may influence terrestrial ecosystems not only via decreasing water uptake of plants, but also by reducing soil organic matter decomposition and the uptake capacity of roots for nutrients such as N and P. This session will focus on small-scale water and nutrient cycling and uptake processes in the root-soil (rhizosphere) and hyphae- soil (hyphosphere) interface under conditions of soil desiccation and/or nutrient limitation, with potential disproportionate consequences for the ecosystem as a total. Among the interests is also belowground carbon allocation via root and mycorrhizal turnover and exudation, which likely plays a critical role for stimulating microbial processing of recalcitrant soil organic matter via priming effects with subsequent increases in nutrient availabilities for plants. We invite contributions from both experimental and modeling studies that focus on developing new methods, testing hypotheses, and identifying knowledge gaps.
