Resumen:
My project is about the effects of fallen trees on soil microbial communities and the processes that they catalyses. Coarse woody debris (which includes fallen logs and braches and large pieces of wood lying on the ground) are important components in temperate forest (where fires are infrequent). These huge quantities of lignocelluloses material, that persist long period of time, creates on the forest floor spatial variability in quality and quantity of above ground organic matter. In the same way that the vegetated shrubs patches in arid ecosystems can be seen as islands of fertility, CWD can be thought as islands of carbon. My central research question is what is the impact of this spatial heterogeneity on the activity and diversity of soil microbial communities? I´m interested in microorganisms because of their central role in decomposition of organic matter, regulation on nutrient cycling and ultimately energy flow and primary production. I want to explore the complexity of microbial communities in order to re think the idea that everything is in everywhere and thought microorganisms as passive catalyst that only response to changes in temperature and soil moisture
