Plant interactions associated with a directional shift in the richness range size relationship during the Glacial-Holocene transition in the Arctic

Nature Communications
A nearly ubiquitous negative relationship between taxonomic richness and mean range-size (average area of taxa) is observed across space. However, the complexity of the mechanism limits its applicability for conservation or range prediction.

Color characteristics of Chinese loess and its paleoclimatic significance during the last glacial-interglacial cycle

, 2016
The soil color is widely used in paleoclimate and paleoenvironment reconstructions in the Chinese Loess Plateau. To better understand the color spatial changes during the glacial -interglacial cycle, the soil color lightness (L-*), characteristic spectra,

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

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Chronostratigraphy, Site Formation, and Palaeoenvironmental Context of Late Pleistocene and Holocene Occupations at Grassridge Rock Shelter (Eastern Cape, South Africa)

Open Quaternary, 2020
Grassridge rock shelter is located in the high elevation grassland foothills of the Stormberg Mountains in the Eastern Cape of South Africa. This places Grassridge at an important biogeoclimatic intersection between the Drakensberg Mountains, the South ...

Comparison of Environments of the Last Interglacial and Holocene in the Lofoten Basin (Norwegian Sea)

Oceanology
Abstract Based on sedimentological, isotope-geochemical, and micropaleontological parameters of bottom sediments of the AMK-5188 core, differences in the natural environment of the last interglacial of the Late Pleistocene (marine oxygen isotope substage 5e) and the Holocene in the Lofoten Basin of the Norwegian

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Holocene Climate Changes: Unraveling Processes, Mechanisms, and Impacts Across Spatiotemporal Scales

Geophysical Research Letters
As the most recent interglacial period and the timeframe for the development of human civilization, the Holocene provides a critical perspective for understanding future climate under continued global warming.

The Early Upper Palaeolithic in British caves: problems and potential Le Paléolithique supérieur ancien dans les grottes de Grande‐Bretagne : problèmes et potentiels

Journal of the Royal Anthropological Institute, EarlyView.
Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

Late Quaternary environmental changes recorded in the Danish marine molluscan faunas: Appendices 1-6 [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2004
Late Quaternary, marine deposits in Denmark have yielded 247 subfossil species of molluscs. The sites are presented, and comparisons are made between the subfossil mollusc assemblages and the 278 shell-bearing mollusc species presently living in the ...
