Towards a metabolic theory of catchments: scaling of water and carbon fluxes with size

Catchments are heterogeneous ecosystems involving several abiotic and biotic processes, where the mutual interactions among water, vegetation, and biogeochemical fluxes take place at different scales. Many biological processes in nature are characterized b ...

More from Less? Environmental Rebound Effects of City Size

Claudia Rebeca Binder Signer, João Vitor Meirelles de Miranda

Global sustainability relies on our capacity of understanding and guiding urban systems and their metabolism adequately. It has been proposed that bigger and denser cities are more resource-efficient than smaller ones because they tend to demand less infra ...

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 ...

Regimes of primary production and their drivers in Alpine streams

Tom Ian Battin, Amber Joy Ulseth, Marta Boix Canadell, Mélanie Clémençon

Primary production is a fundamental ecosystem process that influences nutrient and carbon cycling, and trophic structure in streams. The magnitude and timing of gross primary production (GPP) are typically controlled by hydrology, light, nutrient availa ...

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), ...

Nutrients influence seasonal metabolic patterns and total productivity of Arctic streams

Luis Gómez Gener

The seasonality of gross primary production (GPP) in streams is driven by multiple physical and chemical factors, yet incident light is often thought to be most important. In Arctic tundra streams, however, light is available in saturating amounts througho ...

Thinking like a consumer: Linking aquatic basal metabolism and consumer dynamics

Tom Ian Battin, Marta Boix Canadell, Janine Rüegg

The increasing availability of high‐frequency freshwater ecosystem metabolism data provides an opportunity to identify links between metabolic regimes, as gross primary production and ecosystem respiration patterns, and consumer energetics with the potenti ...

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 ...

Analysis of Resource Productivity and Decoupling in Nepal and Bangladesh

Developing Asian countries such as Nepal and Bangladesh have been doing well in recent years in terms of achieving improved economic growth and environmental performance. This study makes an inventory of historical data on energy and material use/intensiti ...

Continental-scale decrease in net primary productivity in streams due to climate warming

Janine Rüegg

Streams play a key role in the global carbon cycle. The balance between carbon intake through photosynthesis and carbon release via respiration influences carbon emissions from streams and depends on temperature. However, the lack of a comprehensive analys ...
