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

Xaali O’REILLY-BERKELEY, Aloïs Revéret, Youri Lammers, Maaike Zwier et autres

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 …

Rain, wind or fire: which led the PAH fallout in Northern Madagascar across the Holocene?

Emeline Bellet, Vincent Montade, C. Piot, Guillemette Ménot et autres

Abstract. The interactions between wildfire, human and climate variability are not well understood. To have better predictions, past studies are useful for observing their behaviours on a long-time scale. To infer past fire activity, studies used charcoal and molecular biomarkers derived from …

A 3800 year-long sedimentary record of tsunamis and hurricanes in Guadeloupe, Lesser Antilles

Marie Tallon, Pierre Sabatier, Raphaël Paris, Nathalie Feuillet et autres

Guadeloupe is a tropical island in the central Lesser Antilles volcanic arc, exposed to both tectonic and climatic hazards. Subduction of the North American Plate beneath the Caribbean Plate and active shallow faulting generate earthquakes and potential tsunamis, while the island's tropical …

Human and climate impacts on the alpine Critical Zone over the past 10,000 y

William Rapuc, Damien Guinoiseau, Fabien Arnaud, Mathieu Dellinger et autres

Agropastoral activities have impacted the habitable part of our planet-the "Critical Zone"-for thousands of years, triggering a major increase in soil erosion in mountain environments. Understanding and quantifying the impact of these activities on soil is central to the well-being of our …

Reconstructing Anthropocene dynamics of subtropical vegetation and plant diversity by combining sedimentary ancient DNA and pollen: A high-resolution comparative analysis from China’s Yangtze floodplain

Qi Lin, Ke Zhang, Charline Giguet‐Covex, Kai Li et autres

aDNA showed a specific local signal and greater taxonomic resolution for crops and grasses related to cultivated land use, while the pollen records mainly captured regional terrestrial vegetation development especially forestry as well as mixed aquatic plant information mostly linked to littoral …

Multiple late Holocene glacier advances on the sub-Antarctic Kerguelen (49°S) islands: Evidence from a 1200 yr sediment core from a glacial threshold basin

Jarle Børve Sleire, Jostein Bakke, Fabien Arnaud, Pierre Sabatier et autres

Southern Ocean (SO) climate is rapidly changing because of global warming and regional climate feedback loops like shifts of the Southern Hemisphere (SH) westerly winds (SHW) and related Southern Annular Mode (SAM). Over the past decades, the former has been persistently positive, …
