The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Cyperaceae

open access: yes, 1963
Annual or perennial grass-like herbs with short or long rhizomes. Culms trigonous to triquetrous or rarely cylindric and septate (Cyperus articulatus). Leaves narrow, with closed sheaths, sometimes with a ligule opposite to the blade. Inflorescence consisting of a solitary spikelet or capitulum, or many spikelets in heads or spikes or simple to ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Reference wet grasslands to support conservation and restoration assessments in the Brazilian Savanna

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Grassy wetlands of the Cerrado provide key ecosystem services but remain largely overlooked and are rapidly disappearing, threatened by land use change and climate‐driven changes in hydrological cycles. As restoration initiatives are urgent, reference ecosystems and robust indicators are essential to guide conservation and ...
