Regimes of primary production and their drivers in Alpine streams

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

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 ...

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 ...

Daily entropy of dissolved oxygen reveals different energetic regimes and drivers among high‐mountain stream types

Mélanie Clémençon, Tom Ian Battin, Marta Boix Canadell, Luis Gómez Gener

High‐resolution time series of dissolved oxygen (DO) have revealed different ecosystem energetics regimes across various stream types. Ecosystem energetic regimes are relevant to better understand the transformation and retention of nutrients and carbon in ...

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 ...

Glacier retreat changes diurnal variation intensity and frequency of hydrologic variables in Alpine and Andean streams

Tom Ian Battin, Nicolas Thomas Georges Escoffier, Asa Lovisa Viktoria Horgby, Marta Boix Canadell

The impacts of glacier mass and area loss are assumed to affect stream hydrology and related ecosystems. We applied wavelet analysis to high frequency time series of discharge, conductivity, turbidity, air and water temperature in mountain streams influenc ...

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 ...
