Bio
Tom J. Battin was born in Luxembourg (30.06.1966). He holds an MSc in Zoology and a PhD in Aquatic Ecology. He heads the Department of Limnology and Bio-Oceanography at the University of Vienna where he is Full Professor in Limnology. He was visiting Professor at the University of Uppsala (Sweden) and at the University of Applied Arts, Vienna. He has published more than 60 papers on stream microbial ecology and biogeochemistry, and on ecohydraulics. Currently he is editorial board member of Biogeosciences and Aquatic Microbial Ecology. He got awarded a Ramon y Cachal Postdoctoral Fellowship in Spain and a START Prize in Austria.
Abstract
Hastened by the recent recognition that fluvial ecosystems disproportionately contribute to biodiversity and global biogeochemistry, stream and river research is on the rise. Key ecological and biogeochemical processes and patterns in streams and rivers are controlled by the physics of these ecosystems — likely more than in any other aquatic ecosystem. It is therefore of prime importance to consider the coupled physical, chemical and ecological processes in streams and rivers. Clearly this requires an ecohydraulic template for stream and river science.
The Seminar will provide such an ecohydraulic template specifically tailored to the microbial life in streams and the critical functions they fulfill therein. Moving from the micrometer to the multikilometer scale, the Seminar will outline how ecohydraulics affects the architecture, functioning and biodiversity of biofilms — the dominant form of microbial life in streams — and how fluvial network organization shapes microbial diversity of stream biofilms at the large scale. The Seminar will then link small-scale ecohydraulics and the metabolism of organic carbon to large-scale patterns of CO2 outgassing from streams and discuss the physical basis of these carbon fluxes.
The Seminar will conclude by inferring consequences from ecohydraulics for microbial life and biogeochemistry in streams and rivers given future scenarios of altered hydrological regimes and climate extremes. The Seminar will make the case for ecohydraulics as an emerging and necessary field to understand, quantify and predict the consequences of global change for the functions and services stream ecosystems provide.
