A multi‐proxy record of climate variability during the Loch Lomond Stadial (GS‐1) at Old Buckenham Mere, East England, UK

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...

The complex genome and adaptive evolution of polyploid Chinese pepper (Zanthoxylum armatum and Zanthoxylum bungeanum)

open access: yesPlant Biotechnology Journal, Volume 21, Issue 1, Page 78-96, January 2023., 2023
Summary Zanthoxylum armatum and Zanthoxylum bungeanum, known as ‘Chinese pepper’, are distinguished by their extraordinary complex genomes, phenotypic innovation of adaptive evolution and species‐special metabolites. Here, we report reference‐grade genomes of Z. armatum and Z. bungeanum.

Cool episodes in the Late Cretaceous - exploring the effects of physical forcing on Antarctic snow accumulation [PDF]

open access: yes, 2010
Until recently it was assumed that the major modern ice sheets on Antarctica became established around the Eocene-Oligocene boundary about 34 Ma ago. But new evidence (e.g.

Assessing Thermal Maturity of the Pendência Formation (Potiguar Basin) Using Vitrinite Reflectance and Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Palynofacies assemblages from the onshore Potiguar Basin display a wide thermal maturity range, with vitrinite reflectance (%Ro) values of 0.46–2.72 measured from nine samples at depths of 1059–4443 m. A strong correlation exists between %Ro and Raman parameters, specifically the G‐band's full width at half maximum.

Impact of the Water Reservoir and River Engineering Structures on Longitudinal and Transverse (Dis)connectivity Associated With Sediment Transfer

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Human impact in the form of reservoir construction and river regulation downstream of reservoirs, is causing irreversible alterations to hillslope and river channel connectivity in river catchments. This disruption in the dynamic equilibrium of the river is attributed to sediment accumulation upstream of the reservoir's dam, limited sediment ...

Prorocentrum pervagatum sp. nov. (Prorocentrales, Dinophyceae): A new, small, planktonic species with a global distribution

open access: yesPhycological Research, Volume 71, Issue 1, Page 56-71, January 2023., 2023
SUMMARY Prorocentrum comprises a unique group of dinophytes with several apomorphic traits, such as an apical insertion of flagella and the presence of two major, large thecal plates. Species delimitation is challenging, especially for morphologically very similar, small planktonic species.

Decadal Variability of Differential Frost Heave on Incipient Sorted Patterned Ground in the Southern Japanese Alps

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The
