Patterns and controls of carbon dioxide concentration and fluxes at the air–water interface in South American lowland streams Aquat. Sci. (IF 2.755) Pub Date : 2022-03-25 Claudia Feijoó, Maite Arroita, María Laura Messetta, Julieta Anselmo, Laura Rigacci, Daniel von Schiller
Carbon dioxide (CO2) emission from fluvial systems represents a substantial flux in the global carbon cycle. However, variation in fluvial CO2 fluxes at the air–water interface as well as its drivers are poorly understood, especially in non-forested headwaters. Here, we measured CO2 concentration and fluxes in 14 lowland open-canopy streams (Pampean region, Argentina) that cover a wide range of land

Coastal wetlands are valuable aquatic ecosystems with high biological productivity, which provide services such as a reduction in nitrogen loading into coastal waters and storage of organic carbon acting as carbon dioxide sinks. The predicted rise of sea level or freshwater extractions, particularly in the arid Mediterranean biome, will salinize many coastal wetlands. However, there is considerable

Out of gas: re-flooding does not boost carbon emissions from drawdown areas in semiarid reservoirs after prolonged droughts Aquat. Sci. (IF 2.755) Pub Date : 2021-12-08 Pinheiro, Thaís L., Amado, André M., Paranaíba, José R., Quadra, Gabrielle R., Barros, Nathan, Becker, Vanessa
Prolonged droughts in semiarid regions have increased due to climate change and marginal reservoir sediments have been more frequently exposed to the atmosphere. Recent studies suggest that an alternation between dry and re-flooded sediments may increase organic matter (OM) mineralization, boosting greenhouse gas (GHG) emissions to the atmosphere. However, the impact of drying and re-flooding on GHG

As flood events are expected to become more frequent due to climate change, investigating how overland flow exports terrestrial nutrients, carbon and living organisms into aquatic systems is essential for understanding both soil and stream ecosystem status. Here we assessed how dissolved organic carbon (DOC), total suspended sediments (TSS), and stream bacterial diversity responded to stream discharge

Leaf litter decomposition in streams is a fundamental ecosystem process that allows for the cycling of nutrients. The rate at which leaf litter decomposes is greatly controlled by its intrinsic characteristics. However, intraspecific variation in leaf litter characteristics poses a major challenge for large-scale studies aiming at identifying the environmental moderators of leaf litter decomposition

The deposition of excess fine sediment and clogging of benthic substrates is recognised as a global threat to ecosystem functioning and community dynamics. Legacy effects of previous sedimentation create a habitat template on which subsequent ecological responses occur, and therefore, may have a long-lasting influence on community structure. Our experimental study examined the effects of streambed

Zooplankton assemblages in the confined coastal lagoons of La Pletera salt marshes (Baix Ter wetlands, Girona, Spain) are dominated by two species: one calanoid copepod (Eurytemora velox) and the other rotifer (Brachionus gr. plicatilis). They alternate as the dominant species (more than 80% of total zooplankton biomass), with the former being dominant in winter and the latter in summer. Shifts between

Galled leaves are very frequent in southern beech (Nothofagus pumilio) forests. We compared the consumption of leaves (galled and ungalled) by two detritivores and the effect of this consumption on detritivore nutrient content. The amphipod Hyalella curvispina and larvae of the caddisfly Monocosmoecus hyadesi were fed with two diet treatments for 30 days: (1) ungalled leaves and (2) galled leaves.
