The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, EarlyView.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Chukhonastovka – the reference section of the Turonian-Lower Santonian from the Volga-Ilovlya interfluve (the Volga right bank area near Volgograd). Paper 2. Characteristics of the Oryctocomplexes [PDF]

Известия Саратовского университета. Новая серия: Серия Науки о Земле
A representative complex of the Turonian-Santonian carbonate-producing invertebrates has been revealed. It comprised benthic foraminifers, diverse echinoderms, brachiopods, calcareous and siliceous sponges.

Rapid Changes in Southern Ocean Upper‐Water Temperature Linked to Shift of the Southern Hemisphere Westerlies Since the Last Glacial

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The pattern and cause of upper‐water temperature (UWT) variations on millennial timescales in the Southern Ocean (SO) and the mechanism of their interaction with high‐latitude Northern Hemisphere climate remain unclear. Here, we reconstructed millennial‐scale subsurface temperature (subST) records from the Weddell Sea during the Last Glacial ...

Oligocene-Early Miocene Planktonic Microbiostratigraphy and Paleoenvironments of the South Slovakian Basin (Lučenec Depression)

Geologica Carpathica, 2015
Oligocene and Lower Miocene sediments of the Lučenec Depression were studied to demonstrate the planktonic bioevents and climatic proxies from the Číž Formation (Rupelian) and Lučenec Formation (Chattian-Aquitanian) on the basis of quantitative analyses ...

The Renal Function of the Wild Rodent Cerradomys goytaca Reveals Adaptations in the Mechanisms of Urinary Concentration and Solute Excretion

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 772-784, August 2026.
Renal adaptations of Cerradomys goytaca associated with survival in its natural habitat. Graphical Abstract of the main renal physiological characteristics identified in C. goytaca. This species exhibits an increased kidney mass index, elevated urine osmolality, and enhanced tubular water reabsorption, indicating a higher capacity for water ...

MICROFACIES AND MICROFOSSIL ASSEMBLAGES (SMALLER FORAMINIFERS, ALGAE, PSEUDOALGAE) OF THE HUECO GROUP AND LABORCITA FORMATION (UPPER PENNSYLVANIAN-LOWER PERMIAN) SOUTH-CENTRAL NEW MEXICO, USA

Rivista Italiana di Paleontologia e Stratigrafia, 2003
During the latest Carboniferous and earliest Permian (Virgilian-Wolfcampian), the eastern margin of the Orogrande Basin in south-central New Mexico was rimmed by a narrow, tectonically unstable shelf, on which sediments of the Laborcita and Abo ...

Event Deposits Recorded Over the Past 800 kyr in IODP Hole U1433A (South China Sea): Implications of a Revised Methodology for Chronology and Paleoclimate Reconstruction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Instantaneous event deposits such as turbidites, debrites, and slumps are common and frequently occur in marginal seas. These instantaneous deposits represent seconds to days in duration, and can therefore significantly impact age‐depth models and interpretation of paleoclimate history based on thick sedimentary sequences recovered in deep ...

Landscape configuration and soil properties shape ant‐mediated seed dispersal in tropical dry forest agricultural landscapes

Journal of Animal Ecology, Volume 95, Issue 8, Page 1476-1487, August 2026.
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...
