Water Resources Research, Volume 62, Issue 5, May 2026.Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and

Ecological Indicators, 2021 Wetlands are hotspots for various biogeochemical processes, including denitrification. Despite its ecological and economic importance, denitrification has proven difficult to measure.

The Depositional Record, Volume 12, Issue 2, April 2026.During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Mg isotope fractionation during microbial dolomite formation in the Khor Al‐Adaid sabkha, Qatar
The Depositional Record, Volume 12, Issue 2, April 2026.Modern sabkha sediments from southern Qatar show ca. 1‰ Ca isotope fractionation between pore water, organic matter and dolomite, supporting microbial mediation. In contrast, minimal Mg isotope fractionation and inorganic‐like dolomite δ26Mg indicate that microbial influence is indirect, expressed through subtle pore water shifts driven by Mg ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.Abstract Carbon fluxes to Earth's atmosphere are reflected in the carbon isotope composition of atmospheric CO2 (δ13Catm). δ13Catm is used to track past changes to the global carbon cycle and is a variable in many paleoclimate proxies. However, existing δ13Catm proxy records derived from marine carbonates are relatively low‐resolution prior to the ...

GeogacetaThis work is focused on a Lower–Middle Miocene section exposed on the northern flank of Miranda Trebiño piggy-back basin (Cucho section). The sedimentological and stratigraphic study of the section, composed of up to 160 m of terrigenous, mixed (marls),

DISTRIBUTIONAL PATTERNS OF FLORA SPECIES IN RESPONSE TO SALINITY GRADIENTS IN A PALUSTRINE WETLAND [PDF]
Environment & Ecosystem Science, 2019 This study investigated the distributional patterns of species in response to salinity gradients. The vegetation was systematically sampled using a quadrat of 50 x 10 m. Vegetation variables were measured.

The Depositional Record, Volume 12, Issue 1, February 2026.This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.

Subfossil statoblasts of Lophopodella capensis (Sollas, 1908) (Bryozoa, Phylactolaemata, Lophopodidae) in the Upper Pleistocene and Holocene sediments of a montane wetland, Eastern Mau Forest, Kenya [PDF]
African Invertebrates, 2016 Lophopodella capensis (Sollas, 1908) is only known from a limited number of palustrine and lacustrine sites in southern Africa and single sites in both Kenya and Israel. Statoblasts of L.
