Aquatic and terrestrial proxy evidence for Middle Pleistocene palaeolake and lake‐shore development at two Lower Palaeolithic sites of Schöningen, Germany
(Boreas, 2021-05-06)The archaeological sites in the open‐cast mine of Schöningen, Germany, represent outstanding archives for understanding Middle Pleistocene interglacial–glacial transitions and human adaption. Aquatic microfossil and pollen ... -
Late Quaternary paleoenvironmental reconstructions from sediments of Lake Emanda (Verkhoyansk Mountains, East Siberia)
(Journal of Quaternary Science, 2022-05-06)Continuous pollen and chironomid records from Lake Emanda (65°17′N, 135°45′E) provide new insights into the Late Quaternary environmental history of the Yana Highlands (Yakutia). Larch forest with shrubs (alders, pines, ... -
Quantifying the impact of chemicals on stable carbon and oxygen isotope values of raw pollen
(Journal of Quaternary Science, 2021-03-23)Purification protocols to extract pollen from lake sediments contain chemicals that alter the carbon and oxygen pollen‐isotope values according to pollen characteristics and family affiliation. Modern (raw) pollen of ... -
Reversals in Temperature‐Precipitation Correlations in the Northern Hemisphere Extratropics During the Holocene
(Geophysical Research Letters, 2022-11-11)Future precipitation levels remain uncertain because climate models have struggled to reproduce observed variations in temperature‐precipitation correlations. Our analyses of Holocene proxy‐based temperature‐precipitation ... -
Sporopollenin chemistry and its durability in the geological record: an integration of extant and fossil chemical data across the seed plants
(Palaeontology, 2021-01-31)Sporopollenin is a highly resistant biopolymer that forms the outer wall of pollen and spores (sporomorphs). Recent research into sporopollenin chemistry has opened up a range of new avenues for palynological research, ...
