Microbial community ecology across time & space
Silke Langeheder, from Uppsala University in Sweden, will give a talk about "A temporal perspective on community assebmly processes in microbial communities". More about Silke Langeheder at the Uppsala University's web.
During recent years, many studies have shown that different processes including drift, environmental selection and dispersal can be important for determining the spatial distribution of microbial communities in nature. Community assembly is, however, dynamic in space and time and it is therefore important to understand which factors and circumstances influence the relative importance of the different processes. Moreover, legacy effects related to past dispersal events and environmental conditions may influence the composition of present-day communities. In this talk I will present results from both of field work and experimental studies which have the overall aim to investigate (1) how and why community assembly processes vary over time in response to changes in, for example, environmental fluctuations and productivity, and (2) the importance of legacy effects for the composition of bacterial communities in aquatic ecosystems.
