Early to middle Miocene foraminifera from the deep-sea Congo Fan, offshore Angola [PDF]

, 2008
Analysis of a 630m section of an exploration well penetrating the distal part of the Congo Fan (~2000m water depth) yielded high abundance and diversity assemblages of agglutinated and calcareous benthic foraminifera.

The equatorial Pacific High-Productivity Belt: Elements for a Synthesis of Deep Sea Drilling Project Leg 85 Resultspaleoceanography [PDF]

, 1985
Leg 85 of the Deep Sea Drilling Project operated in the eastern central Pacific in the region of the equatorial highproductivity belt. We recovered uppermost Eocene to Quaternary reference sections amenable to fine-scale stratigraphic and ...

Connecting the distribution and diversification of marine plants

Oikos, EarlyView.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

Lithostratigraphy of a long, fossiliferous Oligocene sequence: Revisiting Saint Jacques, Nei Mongol, China

Frontiers in Earth Science, 2023
For a hundred years the Saint Jacques area has been known to produce rich Oligocene vertebrate fossils, yet only a handful of previous studies have focused on this area.

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

PLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Oligocene molasse sedimentation in the Central Taurides: Records of the onset of extensional tectonic regime

Bulletin of the Mineral Research and Exploration, 2020
The lacustrine units have been deposited in the Ermenek, Bucakkışla, Korucuk and Çamlıyayla basins in the Central Taurides since early Oligocene. In this study, structural features and stratigraphical properties of Oligocene basins have been described in

Late Oligocene Formation of the Pearl River Triggered by the Opening of the South China Sea

Geophysical Research Letters, 2023
The Pearl River is one of the largest rivers entering the South China Sea, yet its initiation time remains debated, a topic we address using Pb isotopes in detrital K‐feldspar.

Silicate weathering and carbon cycle controls on the Oligocene-Miocene transition glaciation [PDF]

, 2017
Changes in both silicate weathering rates and organic carbon burial have been proposed as drivers of the transient “Mi-1” glaciation event at the Oligocene-Miocene transition (OMT; ~23 Ma).

Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

Insect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (
