High‐resolution spatial sampling identifies groundwater as driver of CO 2 dynamics in an Alpine stream network

Tom Ian Battin, Amber Joy Ulseth, Asa Lovisa Viktoria Horgby, Marta Boix Canadell

Inland waters are major sources of CO2 to the atmosphere. The origin of this CO2 is often elusive, especially in high‐altitude streams that remain poorly studied at present. Here we study the spatial and seasonal variations in streamwater CO2, its potentia ...

Alpine Glacier Shrinkage Drives Shift in Dissolved Organic Carbon Export From Quasi‐Chemostasis to Transport Limitation

Tom Ian Battin, Amber Joy Ulseth, Nicolas Thomas Georges Escoffier, Marta Boix Canadell

The export of dissolved organic carbon (DOC) from catchments is considered as an important energy flux through streams and a major connection between terrestrial and aquatic systems. However, the impact that predicted hydrological changes due to glacier re ...

Catchment land cover influences macroinvertebrate food-web structure and energy flow pathways in mountain streams

Christopher Robinson, Tom Ian Battin

Understanding how different food resources sustain stream food webs is fundamental towards increasing our knowledge on trophic structure and energy flow pathways in fluvial ecosystems. 2. Food webs in small mountain streams are sustained by autochthonou ...

Ecosystem engineers: Biofilms and the ontogeny of glacier floodplain ecosystems

Matteo Roncoroni, Tom Ian Battin, Jade Brandani

The term “ecosystem engineering” emerged in the 1990s and is commonly used to refer to the activities of larger organisms like beavers and trees in rivers and streams. The focus on larger organisms may be motivated by their more visible effects on the envi ...

Unexpected large evasion fluxes of carbon dioxide from turbulent streams draining the world’s mountains

Enrico Bertuzzo, Tom Ian Battin, Amber Joy Ulseth, Pier Luigi Segatto, Asa Lovisa Viktoria Horgby

Inland waters, including streams and rivers, are active components of the global carbon cycle.Despite the large areal extent of the world’s mountains, the role of mountain streams forglobal carbonfluxes remains elusive. Using recent insights from gas excha ...

Dynamics and potential drivers of CO2 concentration and evasion across temporal scales in high-alpine streams

Tom Ian Battin, Nicolas Thomas Georges Escoffier, Asa Lovisa Viktoria Horgby, Luis Gómez Gener

Carbon dioxide (CO2) evasion from streams greatly contributes to global carbon fluxes. Despite this, the temporal dynamics of CO2 and its drivers remain poorly understood to date. This is particularly true for high-altitude streams. Using high-resolution t ...

Climate-Induced Changes in Spring Snowmelt Impact Ecosystem Metabolism and Carbon Fluxes in an Alpine Stream Network

Enrico Bertuzzo, Tom Ian Battin, Amber Joy Ulseth

Although stream ecosystems are recognized as an important component of the global carbon cycle, the impacts of climate-induced hydrological extremes on carbon fluxes in stream networks remain unclear. Using continuous measurements of ecosystem metabolism, ...

Climate-induced hydrological variation controls the transformation of dissolved organic matter in a subalpine lake

Tom Ian Battin

Lakes are an inherent component of the global carbon cycle. They receive dissolved organic matter (DOM) from the catchment, which is stored, transformed and respired, or delivered downstream. In this study, we show that a subalpine lake shifts its role fro ...

Greenhouse Gas Emissions from Freshwater Reservoirs: What Does the Atmosphere See?

Tom Ian Battin

Freshwater reservoirs are a known source of greenhouse gas (GHG) to the atmosphere, but their quantitative significance is still only loosely constrained. Although part of this uncertainty can be attributed to the difficulties in measuring highly variable ...

Light availability impacts structure and function of phototrophic stream biofilms across domains and trophic levels

Tom Ian Battin

Phototrophic biofilms are ubiquitous in freshwater and marine environments where they are critical for biogeochemical cycling, food webs and in industrial applications. In streams, phototrophic biofilms dominate benthic microbial life and harbour an immens ...

Environmental heterogeneity promotes spatial resilience of phototrophic biofilms in streambeds

Mário Jorge Rodrigues Pereira Da Franca, Andrea Rinaldo, Enrico Bertuzzo, Tom Ian Battin, Carmelo Juez Jiménez, Hannes Markus Peter

The loss of environmental heterogeneity threatens biodiversity and ecosystem functioning. It is therefore important to understand the relationship between environmental heterogeneity and spatial resilience as the capacity of ecological communities embedded ...

High light intensity mediates a shift from allochthonous to autochthonous carbon use in phototrophic stream biofilms

Tom Ian Battin, Amber Joy Ulseth

Changes in the riparian vegetation along stream channels, diurnal light availability, and longitudinal fluctuations in the local light regime in streams influence primary production and carbon (C) cycling in benthic stream biofilms. To investigate the infl ...

Ecological strategies and metabolic trade-offs of complex environmental biofilms

Tom Ian Battin, Hannes Markus Peter

Microorganisms aggregated into matrix-enclosed biofilms dominate microbial life in most natural, engineered, and medical systems. Despite this, the ecological adaptations and metabolic trade-offs of the formation of complex biofilms are currently poorly un ...

Gravel bars are sites of increased CO2 outgassing in stream corridors

Tom Ian Battin

Streams are significant sources of CO2 to the atmosphere. Estimates of CO2 evasion fluxes (fCO2) from streams typically relate to the free flowing water but exclude geomorphological structures within the stream corridor. We found that gravel bars (GBs) are ...

Scaling of dissolved organic carbon removal in river networks

Enrico Bertuzzo, Tom Ian Battin

Streams and rivers play a major role in the global carbon cycle as they collect, transform and deliver terrestrial organic carbon to the ocean. The rate of dissolved organic carbon (DOC) removal depends on hydrological factors (primarily water depth and re ...

Ecohydrological interfaces as hotspots of ecosystem processes

Tom Ian Battin

The movement of water, matter, organisms, and energy can be altered substantially at ecohydrological interfaces, the dynamic transition zones that often develop within ecotones or boundaries between adjacent ecosystems. Interdisciplinary research over the ...

Glacier shrinkage driving global changes in downstream systems

Christopher Robinson, Tom Ian Battin

Glaciers cover ∼10% of the Earth’s land surface, but they are shrinking rapidly across most parts of the world, leading to cascading impacts on downstream systems. Glaciers impart unique footprints on river flow at times when other water sources are low. C ...

The ecology and biogeochemistry of stream biofilms

Tom Ian Battin

Streams and rivers form dense networks, shape the Earth's surface and, in their sediments, provide an immensely large surface area for microbial growth. Biofilms dominate microbial life in streams and rivers, drive crucial ecosystem processes and contribut ...
