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.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Evaluation of the Rb/Sr ratio as an indicator of chemical weathering: a case study from five sedimentary sections in Northeast China

open access: yesBoreas, EarlyView.
Chemical weathering plays a pivotal role in the Earth's surface material cycle and global climate regulation. It not only facilitates the reconstruction of palaeoclimate characteristics but also provides essential insights into Earth's evolutionary history.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

open access: yesThe FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

Ontogenetic and spatial variation in the trophic ecology of the shortfin mako shark (Isurus oxyrinchus) in temperate eastern Australia

open access: yesJournal of Fish Biology, EarlyView.
Abstract The shortfin mako (Isurus oxyrinchus) is a fast‐swimming pelagic shark of global ecological and socioeconomic importance, yet it is relatively understudied in temperate eastern Australian waters. This study investigated the trophic ecology of mako sharks using stable isotope analysis (SIA) of nitrogen (δ15N), carbon (δ13C) and sulphur (δ34S ...
