Attached biofilms and suspended aggregates are distinct microbial lifestyles emanating from differing hydraulics

Tom Ian Battin, Hannes Markus Peter

Small-scale hydraulics affects microbial behaviour at the cell level1, trophic interactions in marine aggregates2 and the physical structure and function of stream biofilms3,4. However, it remains unclear how hydraulics, predictably changing from small str ...

Storage and release of organic carbon from glaciers and ice sheets

Tom Ian Battin

Polar ice sheets and mountain glaciers, which cover roughly 11% of the Earth's land surface, store organic carbon from local and distant sources and then release it to downstream environments. Climate-driven changes to glacier runoff are expected to be lar ...

Light availability affects stream biofilm bacterial community composition and function, but not diversity

Tom Ian Battin

Changes in riparian vegetation or water turbidity and browning in streams alter the local light regime with potential implications for stream biofilms and ecosystem functioning. We experimented with biofilms in microcosms grown under a gradient of light in ...

Altitudinal patterns of diversity and functional traits of metabolically active microorganisms in stream biofilms

Tom Ian Battin, Hannes Markus Peter

Resources structure ecological communities and potentially link biodiversity to energy flow. It is commonly believed that functional traits (generalists versus specialists) involved in the exploitation of resources depend on resource availability and envir ...

Light and hydrologic variability as drivers of stream biofilm dynamics in a flume experiment

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Lorenzo Mari, Marino Gatto, Gianluca Botter, Tom Ian Battin

We run a comparative study of the results of flume experiments and several dynamic models reproducing the effects of streamflow variability on biofilm (i.e. periphyton) temporal dynamics. During the experiment, two contrasting flow regimes, characterised b ...

Fluvial network organization imprints on microbial co-occurrence networks

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Tom Ian Battin

Recent studies highlight linkages among the architecture of ecological networks, their persistence facing environmental disturbance, and the related patterns of biodiversity. A hitherto unresolved question is whether the structure of the landscape inhabite ...

Hydrologic controls on basin- scale distribution of benthic invertebrates

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Tom Ian Battin

Streamflow variability is a major determinant of basin-scale distributions of benthic invertebrates. Here we present a novel procedure based on a probabilistic approach aiming at a spatially explicit quantitative assessment of benthic invertebrate abundanc ...

Hydrologic Variability Affects Invertebrate Grazing on Phototrophic Biofilms in Stream Microcosms

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Lorenzo Mari, Gianluca Botter, Tom Ian Battin

The temporal variability of streamflow is known to be a key feature structuring and controlling fluvial ecological communities and ecosystem processes. Although alterations of streamflow regime due to habitat fragmentation or other anthropogenic factors ar ...

Biophysical controls on cluster dynamics and architectural differentiation of microbial biofilms in contrasting flow environments

Andrea Rinaldo, Enrico Bertuzzo, Samir Suweis, Lorenzo Mari, Tom Ian Battin

Ecology, with a traditional focus on plants and animals, seeks to understand the mechanisms underlying structure and dynamics of communities. In microbial ecology, the focus is changing from planktonic communities to attached biofilms that dominate microbi ...

Headwaters are critical reservoirs of microbial diversity for fluvial networks

Enrico Bertuzzo, Tom Ian Battin

Streams and rivers form conspicuous networks on the Earth and are among nature's most effective integrators. Their dendritic structure reaches into the terrestrial landscape and accumulates water and sediment en route from abundant headwater streams to a s ...
