River ecosystem metabolism and carbon biogeochemistry in a changing world

Tom Ian Battin, Enrico Bertuzzo, Luis Gómez Gener

River networks represent the largest biogeochemical nexus between the continents, ocean and atmosphere. Our current understanding of the role of rivers in the global carbon cycle remains limited, which makes it difficult to predict how global change may al ...

Glacier retreat and increasing vegetation cover alter the sources and sinks of organic and inorganic carbon in alpine streams

Nicola Deluigi, Andrew Lean Robison

High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the greening of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, g ...

Glacier loss and vegetation expansion alters organic and inorganic carbon dynamics in alpine streams

Tom Ian Battin, Nicola Deluigi, Andrew Lean Robison, Camille Aude Rolland

High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the ‘greening’ of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, ...

The Metabolic Regimes at the Scale of an Entire Stream Network Unveiled Through Sensor Data and Machine Learning

Tom Ian Battin, Enrico Bertuzzo, Pier Luigi Segatto

Streams and rivers form dense networks that drain the terrestrial landscape and are relevant for biodiversity dynamics, ecosystem functioning, and transport and transformation of carbon. Yet, resolving in both space and time gross primary production (GPP), ...

Modeling of Stream Metabolism from Reach-scale to the Scale of Entire River Networks

Pier Luigi Segatto

Streams are key components of the global carbon (C) cycle. The river network conceptualization moved from the pipelineâ idea, in which C is solely transported, to the active ecosystemâ concept, in which both terrestrial derived and autochthonous C ...

Primary and Net Ecosystem Production in a Large Lake Diagnosed From High-Resolution Oxygen Measurements

Alfred Johny Wüest, Camille Roland Marie Minaudo, Bieito Fernandez Castro, Hannah Elisa Chmiel, Shubham Krishna, Pascal Perolo

The rates of gross primary production (GPP), ecosystem respiration (R), and net ecosystem production (NEP) provide quantitative information about the cycling of carbon and energy in aquatic ecosystems. In lakes, metabolic rates are often diagnosed from die ...

Increasing carbon-to-phosphorus ratio (C:P) from seston as a prime indicator for the initiation of lake reoligotrophication.

Alfred Johny Wüest

Decline in total phosphorus (TP) during lake reoligotrophication does not apparently immediately influence carbon assimilation or deep-water oxygen levels. Traditional monitoring and interpretation do not typically consider the amount of organic carbon exp ...

Net ecosystem production of lakes estimated from hypolimnetic organic carbon sinks

Alfred Johny Wüest

This study presents a novel concept for estimating net ecosystem production (NEP), the export of organic carbon (OC) from the productive surface layer to the deep‐water (hypolimnion) of eleven seasonally stratified lakes, varying in depth and trophic state ...

Assessing the responses of Sphagnum micro-eukaryotes to climate changes using high throughput sequencing

Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey, Mariusz Lamentowicz, Enrique Lara

Current projections suggest that climate warming will be accompanied by more frequent and severe drought events. Peatlands store ca. one third of the world's soil organic carbon. Warming and drought may cause peatlands to become carbon sources through stim ...

Carbon fluxes and productivity regimes in Alpine streams

Marta Boix Canadell

High-altitude catchments have a major role in the transport of organic matter to streams due to the storage of dissolved organic carbon (DOC) in soils and glacier ice and the subsequent mobilization during the melting processes. Yet, stream function goes b ...
