Carbon Emissions From Low‐Order Streams in a Tropical, High‐Elevation, Peatland Ecosystem Are Mediated by Catchment Morphology

Water Resources Research · 2025-04-01 · 3 citations

Abstract Inland waters emit large amounts of carbon and are key players in the global carbon budget. Particularly high rates of carbon emissions have been reported in streams draining mountains, tropical regions, and peatlands. However, few studies have examined the spatial variability of CO 2 concentrations and fluxes occurring within these systems, particularly as a function of catchment morphology. Here we evaluated spatial patterns of CO 2 in three tropical, headwater catchments in relation…

Amphibitic stoneflies (Plecoptera) are integrators of ecosystem processes in alluvial aquifers of gravel‐bed river floodplains

Wiley Interdisciplinary Reviews Water · 2024-02-07 · 3 citations

Abstract Over 50 years ago nymphs of the Plecoptera species, Paraperla frontalis Banks, 1906 (Plecoptera: Chloroperlidae), were shown to exist in a shallow floodplain aquifer of the Tobacco River, a gravel‐bed river in western Montana and later they were documented throughout the main stems of the Flathead River system. Nymphs are almost never found in surface waters, until they emerge on the river shorelines. As teneral adults, they mate and subsequently deposit fertilized eggs into the river.…

Cryptic chemoautotrophic and methanotrophic processes complicate the use of carbon stable isotopes in rivers

2025-03-31 · 1 citations

The use of carbon stable isotopes has contributed to many important discoveries regarding the base of consumer production in freshwater ecosystems. There is increasing recognition for the prevalence of anoxic conditions and the contributions of methane-derived carbon to freshwater food webs, highlighting the potential for methanotrophy and chemoautotrophy to complicate interpretations of δ13C values in consumer biomass. These reduced substrates are sometimes cryptic, or present at such low conce…
