Biophysical properties at patch scale shape the metabolism of biofilm landscapes

Tom Ian Battin, Hannes Markus Peter, Anna Depetris

Phototrophic biofilms form complex spatial patterns in streams and rivers, yet, how community patchiness, structure and function are coupled and contribute to larger-scale metabolism remains unkown. Here, we combined optical coherence tomography with autom ...

Morphogenesis and oxygen dynamics in phototrophic biofilms growing across a gradient of hydraulic conditions

Amin Niayifar, Tom Ian Battin, Hannes Markus Peter, Anna Depetris, Michael Kühl

Biofilms are surface-attached and matrix-enclosed microbial communities that dominate microbial life in numerous ecosystems. Using flumes and automated optical coherence tomography, we studied the morphogenesis of phototrophic biofilms along a gradient of ...

The architecture of benthic biofilms - Linking hydraulics to spatially structured processes

Anna Depetris

Biofilms are spatially structured ecosystems, characterized by patterns and architectural features determined by the interplay between endogenous and exogenous processes. As in many other structured ecosystems, the characterization of spatial interactions ...

Flow and epiphyte growth effects on the thermal, optical and chemical microenvironment in the leaf phyllosphere of seagrass (Zostera marina)

Anna Depetris, Michael Kühl

Intensified coastal eutrophication can result in an overgrowth of seagrass leaves by epiphytes, which is a major threat to seagrass habitats worldwide, but little is known about how epiphytic biofilms affect the seagrass phyllosphere. The physico-chemical ...

Automated 3D Optical Coherence Tomography to Elucidate Biofilm Morphogenesis Over Large Spatial Scales

Antoine Wiedmer, Tom Ian Battin, Hannes Markus Peter, Anna Depetris

Biofilms are a most successful microbial lifestyle and prevail in a multitude of environmental and engineered settings. Understanding biofilm morphogenesis, that is the structural diversification of biofilms during community assembly, represents a remarkab ...
