The role of nitrogen and iron biogeochemical cycles in the production and export of dissolved organic matter in agricultural headwater catchments

Thibault Lambert, Rémi Dupas, Patrick Durand

To better understand the seasonal variations in environmental conditions regulating dissolved organic matter (DOM) export in agricultural headwater catchments, we combined the monitoring of nitrate, iron, soluble phosphorus, and DOM concentration (as dissolved organic carbon; DOC) and composition (3D fluorescence) in soil …

Role of nitrogen and iron biogeochemical cycles on the production and export of dissolved organic matter in agricultural headwater catchments

Thibault Lambert, Rémi Dupas, Patrick Durand

Abstract. To obtain better constraints on the control of the seasonal variations on dissolved organic carbon (DOC) export in lowland catchments, we combined monitoring of nitrates, iron, soluble phosphorus and dissolved organic matter concentration (as DOC) and composition (fluorescence) in soil and …

The influence of nitrogen and iron biogeochemical cycles on the production and export of dissolved organic matter in headwater catchments

Rémi Dupas, Thibault Lambert, Patrick Durand

Dissolved organic carbon (DOC) in surface waters originates mainly from riparian soils, where several processes affect the mobilisation/immobilisation of organic compounds. Among these processes, iron reduction is thought to be of primary importance for DOC mobilisation and export to surface waters. However, …

Near‐bed stratification controls bottom hypoxia in ice‐covered alpine lakes

Marie‐Elodie Perga, Camille Minaudo, Tomy Doda, Florent Arthaud et autres

Abstract In ice‐covered lakes, near‐bottom oxygen concentration decreases for most of the wintertime, sometimes down to the point that bottom waters become hypoxic. Studies insofar have reached divergent conclusions on whether climate change limits or reinforces the extent and duration of hypoxia …

Greenhouse gas emissions from African lakes are no longer a blind spot

Alberto Vieira Borges, Loris Deirmendjian, Steven Bouillon, William Okello et autres

Natural lakes are thought to be globally important sources of greenhouse gases (CO 2 , CH 4 , and N 2 O) to the atmosphere although nearly no data have been previously reported from Africa. We collected CO 2 , CH 4 …

Lowland plant arrival in alpine ecosystems facilitates a decrease in soil carbon content under experimental climate warming

Tom W. N. Walker, Konstantin Gavazov, Thomas Guillaume, Thibault Lambert et autres

Climate warming is releasing carbon from soils around the world, constituting a positive climate feedback. Warming is also causing species to expand their ranges into new ecosystems. Yet, in most ecosystems, whether range expanding species will amplify or buffer expected soil carbon …

Author response: Lowland plant arrival in alpine ecosystems facilitates a decrease in soil carbon content under experimental climate warming

Tom W. N. Walker, Konstantin Gavazov, Thomas Guillaume, Thibault Lambert et autres

In a terrestrial ecosystem, the carbon cycle primarily represents the balance between plants consuming carbon dioxide from the atmosphere and soil microbes releasing carbon stored in the soil into the atmosphere (mostly as carbon dioxide). Given that carbon dioxide traps heat in …

Whiting Events in a Large Peri‐Alpine Lake: Evidence of a Catchment‐Scale Process

Nicolas Escoffier, Pascal Perolo, Thibault Lambert, Janine Rüegg et autres

Abstract Whiting events are transient phenomena commonly occurring in hardwater lakes and manifesting as a turquoise coloration of surface waters during massive calcium carbonate precipitation. While biological and physico‐chemical drivers of carbonate precipitation are known, their relative contributions in controlling whiting events' …
