Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils

open access: yesThe Anatomical Record, EarlyView.
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

open access: yesBoreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Increased arbuscular mycorrhizal fungal biomass and diversity in soil under long‐term climate drying and warming

open access: yesNew Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) support critical ecosystem services including plant resource acquisition and productivity. AMF functional traits such as relative biomass investment in root vs soil colonization or drought tolerance are thought to be evolutionarily conserved within AMF lineages and might influence AMF community responses to ...

Grassland age and local adaptation shape drought resilience across semi‐natural grassland populations

open access: yesNew Phytologist, EarlyView.
Field sampling sites and mesocosm experimental design. Summary Increasing frequency and intensity of droughts threaten grassland ecosystems. Semi‐natural grasslands vary in age from ancient to younger sites established on former arable land. While species richness and composition are known to affect drought resilience, little is known about how ...
