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 ...

Regimes of primary production and their drivers in Alpine streams

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

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 ...

Integrating Discharge-Concentration Dynamics Across Carbon Forms in a Boreal Landscape

Luis Gómez Gener

The flux of terrestrial carbon across land-water boundaries influences the overall carbon balance of landscapes and the ecology and biogeochemistry of aquatic ecosystems. The local consequences and broader fate of carbon delivered to streams is determined ...

Global carbon dioxide efflux from rivers enhanced by high nocturnal emissions

Tom Ian Battin, Hannes Markus Peter, Asa Lovisa Viktoria Horgby, Luis Gómez Gener

Carbon dioxide (CO2) emissions to the atmosphere from running waters are estimated to be four times greater than the total carbon (C) flux to the oceans. However, these fluxes remain poorly constrained because of substantial spatial and temporal variabilit ...

Towards an improved understanding of biogeochemical processes across surface-groundwater interactions in intermittent rivers and ephemeral streams

Luis Gómez Gener, Oleksandra Shumilova

Surface-groundwater interactions in intermittent rivers and ephemeral streams (IRES), waterways which do not flow year-round, are spatially and temporally dynamic because of alternations between flowing, non-flowing and dry hydrological states. Interaction ...

Delineating the Continuum of Dissolved Organic Matter in Temperate River Networks

Luis Gómez Gener

The origin and reactivity of dissolved organic matter (DOM) have received attention for decades due to the key role DOM plays in global carbon cycling and the ecology of aquatic systems. However, DOM dynamics in river networks remain unresolved, hampered b ...

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

Tom Ian Battin, Mélanie Clémençon, 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 ...

Drought alters the biogeochemistry of boreal stream networks

Luis Gómez Gener

Drought is a global phenomenon, with widespread implications for freshwater ecosystems. While droughts receive much attention at lower latitudes, their effects on northern river networks remain unstudied. We combine a reach-scale manipulation experiment, o ...

Early-Career Coordinated Distributed Experiments: Empowerment Through Collaboration

Luis Gómez Gener

Coordinated distributed experiments (CDEs) enable the study of large-scale ecological patterns in geographically dispersed areas, while simultaneously providing broad academic and personal benefits for the participants. However, the effective involvement o ...
