Biomarker proxies for reconstructing Quaternary climate and environmental change
To reconstruct past environmental changes, a range of indirect or proxy approaches can be
applied to Quaternary archives. Here, we review the complementary and novel insights that …

Coupling of the ecosystems in North China with the East Asian summer monsoon rainfall during the Holocene
Abstract The influence of Holocene East Asian Summer Monsoon (EASM) rainfall on
ecosystems over northern China remains controversial: delay or synchronization. Here we …

Group 2i Isochrysidales produce characteristic alkenones reflecting sea ice distribution
Alkenones are biomarkers produced solely by algae in the order Isochrysidales that have
been used to reconstruct sea surface temperature (SST) since the 1980s. However …

Phylogeny, alkenone profiles and ecology of Isochrysidales subclades in saline lakes: Implications for paleosalinity and paleotemperature reconstructions
Long-chain alkenones (LCAs) produced by phylogenetically classified Groups 1 and 3
Isochrysidales are increasingly used for paleotemperature and/or paleosalinity …

Group 2i Isochrysidales flourishes at exceedingly low growth temperatures (0 to 6° C)
Abstract Group 2i Isochrysidales (Haptophyta) microalgae were recently suggested to be the
main producer of the C 37: 4 alkenone in high latitude oceans with seasonal sea ice …

C41 methyl and C42 ethyl alkenones are biomarkers for Group II Isochrysidales
Alkenones are polyunsaturated long-chain methyl or ethyl ketones produced by species in
the Isochrysidales, an order of haptophyte algae. Based on phylogenetic data, members of …

Machine learning reveals that sodium concentration and temperature influence alkenone occurrence in Swiss and worldwide freshwater lakes
Lacustrine alkenones are increasingly reported in freshwater lakes worldwide, which makes
them a very promising proxy to reconstruct past continental temperatures. However, a more …

Group 2i Isochrysidales thrive in marine and lacustrine systems with ice cover
Global warming is causing rapid changes to the cryosphere. Predicting the future trajectory
of the cryosphere requires quantitative reconstruction of its past variations. A recently …

Abrupt cooling of cold seasons at the middle-late Holocene transition revealed by alkenone records from North China
In saline lakes, the paleoenvironmental interpretation of long-chain alkenones (LCAs) is
difficult due to the inputs of Isochrysidales Group 2i, which are ice-related bloomers. Here …

Extended chain length alkenoates differentiate three Isochrysidales groups
Alkenoates and alkenones are polyunsaturated long-chain esters and ketones produced by
members of the Isochrysidales, an order of haptophyte microalgae. Based on phylogenetic …
