Legacy Knowledge on Landscape Soil Carbon—Concentrated Organic Input to Selected Sites Comes With the Expense of Soil Health of Larger Areas

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Xu et al. show that high organic input and N‐balancing fertilization improve soil health at the soil plot scale; however, the effects of allocating C and N on soil health at the landscape or region scale are not considered. Historical soil management systems show that such a depletive redistribution leads to local agricultural improvements ...

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 ...

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.
