DOI: 10.1016/j.gca.2019.06.032
Abstract: Abstract The alkenone-pCO2 method is one of the most widely used approaches to reconstruct atmospheric CO2 in the Cenozoic. The method depends upon fractionation of stable carbon isotopes during algal photosynthesis, expressed as ep37:2, and… read more here.

DOI: 10.1029/2025gl116748
Abstract: The South China Sea (SCS) nitrogen cycle responds dynamically to glacial–interglacial climate changes, yet the drivers of nitrogen isotope variability remain debated. We present a synthesis of foraminifera‐bound δ15N (FB‐δ15N) records, together with complementary organic… read more here.

DOI: 10.1073/pnas.2206085119
Abstract: Significance The deposition of mineral dust can stimulate primary productivity in the remote Southern Ocean through the supply of the micronutrient iron (Fe), leading to a removal of atmospheric CO2 especially during glacial periods. By… read more here.

DOI: 10.1093/aob/mcy235
Abstract: Background and Aim Quaternary glaciations strongly affected the distribution of species from arid and semi-arid environments, as temperature drops were accompanied by strong fluctuations in rainfall. In this study, we examined the response of xerophytic… read more here.

DOI: 10.1111/jbi.14023
Abstract: Spatio‐temporal changes have likely caused range fragmentation and population isolation, which could have given rise to the observed current intraspecific differentiation in some species. Here, we test several hypotheses on the potential effect of Pleistocene… read more here.

DOI: 10.1111/mec.16166
Abstract: Pleistocene glacial cycles influenced the diversification of high-latitude wildlife species through recurrent periods of range contraction, isolation, divergence, and expansion from refugia and subsequent admixture of refugial populations. We investigate population size changes and the… read more here.

The opposed forces of differentiation and admixture across glacial cycles in the butterfly Aglais urticae
Sign Up to like & getrecommendations! Published in 2024 at "Molecular Ecology"
DOI: 10.1111/mec.17304
Abstract: Glacial cycles lead to periodic population interbreeding and isolation in warm‐adapted species, which impact genetic structure and evolution. However, the effects of these processes on highly mobile and more cold‐tolerant species are not well understood.… read more here.
