Geochemistry of low‐temperature dolomite formation in coastal and continental saline to sabkha‐like environments

The Depositional Record, Volume 12, Issue 4, September 2026.
This study compares primary dolomite precipitation in modern and ancient environments, varying from coastal to transitional to continental saline environments. The microbially mediated dolomites are characterised by high Sr concentrations. Here, various geochemical proxies are studied and compared to previous findings.

Sedimentology and geochemistry of the recent sediments of the river system on Hurd Peninsula, Livingston Island, Antarctica

The Depositional Record, Volume 12, Issue 4, September 2026.
This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Diagenetic evolution and geochemical controls on carbonate platform development in the Middle Eocene Jahrum Formation, Zagros Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Integrated petrographic, mineralogical and geochemical workflow for reconstructing the diagenetic evolution of the Middle Eocene Jahrum Formation in the Zagros Basin. The diagram illustrates the methodological framework combining field observations, laboratory analyses (XRD, SEM‐EDS, stable isotopes, cathodoluminescence), pyrite framboid geochemistry ...

Evolutionary Imprints on the Foliar Elementome: Biogeochemical Niche Differentiation Among Fagus Species

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study compared the biogeochemical niches of three Fagus species (F. grandifolia, F. sylvatica, and F. crenata) using foliar nutrient data from 328 sites, revealing distinct elemental compositions and unique nutrient acquisition strategies. Phosphorus and calcium primarily distinguished F. sylvatica, whereas F.

Mitogenomic and Ecological Perspectives on the Wide‐Ridged Indo‐Pacific Finless Porpoise Neophocaena phocaenoides: Toward Emerging Conservation Strategies

Ecology and Evolution, Volume 16, Issue 9, September 2026.
IUCN‐defined extant distribution of the Indo‐Pacific finless porpoise (Neophocaena phocaenoides), overlaid with occurrence records, global Marine Protected Areas (MPAs), and Important Marine Mammal Areas (IMMAs). ABSTRACT Prior to this study, the narrow‐ridged finless porpoise (Neophocaena asiaeorientalis) had been extensively studied across East Asia,
