The Plio‐Pleistocene succession of the Po Plain Basin was interpreted basin‐wide using seismic profiles and well data, identifying six major tectonic unconformities. Sediment volumes were calculated and decompacted to assess tectonic and climatic controls on basin infill, revealing a marked increase in detrital flux after 1.5 Ma, coincident with the ...

ABSTRACT Natural inland wetlands in Southeast Asia provide key biodiversity, hydrological, carbon‐storage and livelihood functions, but are increasingly affected by land‐use change, fire, hydrological modification and climate change and variability.

ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.

Quantifying errors in coral-based ENSO estimates: toward improved forward modeling of δ18O
The oxygen isotopic ratio (δ18O) in tropical Pacific coral skeletons reflects past El Niño-Southern Oscillation (ENSO) variability, but the δ18O-ENSO relationship is poorly quantified.

Dolomitic Microfossil Preservation in a Cryogenian Microbial Reef, Arkaroola (South Australia)
ABSTRACT Microbial dolostones that now form the Arkaroola reef, northern Adelaide Rift Complex, and were deposited during the Cryogenian interglacial period, display a wide range of meso‐scale stromatolite morphotypes in outcrop. Microcharacterisation involving optical microscopy, combined scanning electron microscopy and energy dispersive spectroscopy

Red to Green: A Lipid Biomarker Record of Tonian‐Ediacaran Algae in Siberia
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

δ13C and δ18O Isotopic Analysis of a Platygonus compressus Tusk
Stable-isotope analysis of Platygonus compressus remains from Peccary Cave, AR documents previously unknown dietary and seasonal information on flat-headed peccary. P. compressus diet knowledge currently derives from dental wear analyses with no isotopic

Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.

Abstract The light element distribution in planetary cores and the processes driving core evolution in rocky planets are poorly understood. Magmatic iron meteorites are samples from the cores of ancient embryonic planetesimals and therefore provide a window into the processes governing core evolution. We performed high precision oxygen isotope analyses
