Differentiating biological and chemical factors of top and deep soil carbon sequestration in semi-arid tropical Inceptisol: an outcome of structural equation modeling

open access: yesCarbon Management, 2020
Though soils sequester large amounts of carbon (C), variations in physical and chemical characteristics of top and deep layers necessitate the study of factors governing topsoil and deep soil C sequestration to predict land-use changes to alleviate ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

open access: yesJournal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Assessing the intensity of Late Quaternary humid phases in the Nefud Desert, northern Arabia

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The climate history of the major dryland zones of the world, such as the Saharo–Arabian Desert belt, plays a key role in the dispersal of early humans through these intermittently inhospitable regions. Here, we assess the relative intensity of Late Quaternary humid phases in northern Arabia through lithological, geochemical, palaeoecological ...

Holocene climate oscillations, seismotectonic events and human–environmental interactions reconstructed from the Giannades palaeolake on Corfu (Eastern Mediterranean, Greece)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Mediterranean is particularly sensitive to rapid climate changes (RCCs) during the Holocene. An increasing number of natural climate archives revealed that socio‐economic developments were influenced by such RCCs since the Palaeolithic. However, multi‐millennial and high‐resolution archives are still rare and often located in mountainous ...

Hidden Insights: Comprehensive Radiological Analysis of Four Skeletal Populations From 13th–19th Century Southern Finland Reveals Neoplastic and Other Lesions Invisible on Bone Surfaces

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study aims to identify lesions confined to the internal structures of bones. A radiographic analysis was performed on 219 archaeological, historical period skeletons from southern Finland. Although the study examines nearly all preserved skeletal elements using plain radiographs, it does not incorporate computed tomography.

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

open access: yesPeople and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Detecting and attributing climate change effects on vegetation: Australia as a test case

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.
