Spatially heterogenous range dynamics since the Last Glacial Maximum underpin the modern bimodal latitudinal diversity gradient in planktonic foraminifera

Ecography, EarlyView.
The modern latitudinal diversity gradient (LDG) of planktonic foraminifera is bimodal, with a distinct depression near the equator surrounded by mid‐latitude diversity peaks. This pattern emerged after the Last Glacial Maximum (LGM; 19–23 ka), but it remains unclear how species' spatial dynamics contributed to its formation.

Palaeobiology, palaeoecology and stratigraphic significance of the Late Miocene cockle Lymnocardium soproniense from Lake Pannon

Geologica Carpathica, 2016
Stratigraphic subdivision of the Upper Miocene deposits in the Pannonian Basin has been traditionally based on the endemic mollusc species of Lake Pannon.

Suppressed competitive exclusion enabled the proliferation of Permian/Triassic boundary microbialites

The Depositional Record, 2020
During the earliest Triassic microbial mats flourished in the photic zones of marginal seas, generating widespread microbialites. It has been suggested that anoxic conditions in shallow marine environments, linked to the end‐Permian mass extinction ...

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Carbon cycle changes during the Triassic-Jurassic transition [PDF]

, 2010
The end-Triassic is regarded as one of the five major mass extinction events of the Phanerozoic. This time interval is marked by up to 50% of marine biodiversity loss and major changes in terrestrial ecosystems. Mass extinction events are often marked by

Late Pleistocene to Holocene human palaeoecology in the tropical environments of coastal eastern Africa [PDF]

, 2020
The ecological adaptations that stimulated the dispersal and technological strategies of our species during the Late Pleistocene remain hotly disputed, with some influential theories focusing on grassland biomes or marine resources as key drivers behind ...

Complexities of Stable Carbon and Nitrogen Isotope Biogeochemistry in Ancient Freshwater Ecosystems: Implications for the Study of Past Subsistence and Environmental Change

Frontiers in Ecology and Evolution, 2019
Stable carbon and nitrogen isotope analyses of human and animal tissues have become an important means of studying both anthropogenic and natural food webs in aquatic ecosystems.

CHARACTERISTICS OF THE FACIES AND RADIOLITID PALEOENVIRONMENT OF THE UPPER CENOMANIAN SHALLOW-WATER SUCCESSION FROM THE SOUTHERN PART OF THE ADRIATIC CARBONATE PLATFORM, NORTHWESTERN SIDE OF KORČULA ISLAND, CROATIA

Rudarsko-geološko-naftni Zbornik, 2023
Upper Cenomanian limestones from the northwestern part of the island of Korčula in Croatia are shallow-water Chondrodonta-level deposits that represent a lateral equivalent of a foundered platform paleoenvironment.

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

Journal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Palaeoenvironmental changes and vegetation history during the Triassic-Jurassic transition [PDF]

, 2010
The Triassic-Jurassic (T-J) boundary, ~200 Ma, is known as one of the ‘big five’ mass extinctions in Earth’s history. The T-J transition is characterized by a major extinction in the marine realm but evidence for floral turnover is ambiguous ...
