Early Holocene occurrence of thermophilous trees in the Storulvån valley by Andersson, Daniella

“…Makrofossiler påträffade i området kring Storulvån i västra Jämtland bekräftar förekomst av Ulmus glabra, Quercus robur and Corylus avellana under Holocens inledande århundraden. Syftet med studien är att undersöka förekomsten av nemorala trädslag i Storulvåområdet under hela Holocene genom att utvärdera förekomsten av pollen av Ulmus, Quercus, Tilia och Corylus i torvlagerföljder. …”

The genome landscape of Tibetan sheep reveals adaptive introgression from argali and the history of early human settlements on the Qinghai-Tibetan Plateau by Xiao-Ju Hu, Ji Yang, Xing-Long Xie, Feng-Hua Lv, Yin-Hong Cao, Wen-Rong Li, Ming-Jun Liu, Yu-Tao Wang, Jin-Quan Li, Yong-Gang Liu, Yan-Lin Ren, Zhi-Qiang Shen, Han Jianlin, Meng-Hua Li

“…Together with archeological evidence, the date and route reveal the history of human expansions on the QTP by the Tang–Bo Ancient Road during the late Holocene. Our findings contribute to a depth understanding of early pastoralism and the local adaptation of Tibetan sheep as well as the late-Holocene human occupation of the QTP.…”

Can pollution bias peatland palaeoclimate reconstruction? by Payne, R.J., Mitchell, E.A.D., Hung Nguyen-Viet, Gilbert, D.

“…Peatlands around the world have been exposed to anthropogenic and intermittent natural pollution through the late Holocene. This raises the question: can pollution lead to changes in the testate amoeba paleoecological record that could be erroneously interpreted as a climatic change? …”

Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina by Mora, Matias Sebastian, Mapelli, Fernando Javier, Lopez, Aldana, Gomez Fernandez, Maria Jimena, Mirol, Patricia Monica, Kittlein, Marcelo Javier

“…“chasiquensis” appear to be a relicts of a more extended historical distribution in the Argentinean Pampas in the Late Pleistocene, with a perceptible population decline at the beginning of the Holocene. In this context, Bayesian demographic inferences showed a small but constant increment of population expansion of this species from approximately 90,000 to 11,000 years BP, after which a period of decrease in population size (that started in the early Holocene and continues nowadays) was observed.…”

Ecotypic differentiation under farmers' selection: Molecular insights into the domestication of Pachyrhizus Rich. ex DC. (Fabaceae) in the Peruvian Andes by Deletre, M., Soengas, B., Vidaurre, P.J., Meneses, R.I., Delgado Vasquez, O., Ore Balbin, I., Santayana, M., Heider, B., Sorensen, M.

“…The new molecular data call for a revision of the taxonomy of Pachyrhizus but are congruent with paleoclimatic and archeological evidence, and suggest that selection for determinate growth was part of ecophysiological adaptations associated with the diversification of the P. tuberosus–P. ahipa complex during the Mid-Holocene.…”

Comparative phylogeography of Aedes mosquitoes and the role of past climatic change for evolution within Africa by Bennett, K.L., Kaddumukasa, M., Shija, F., Djouaka, R., Misinzo, G., Lutwama, J., Linton, Y.M., Walton, C.

“…This congruence in evolutionary history is likely to relate to historical climate‐driven habitat change within Africa during the late Pleistocene and Holocene epoch. We find differences in the population structure of mosquitoes from Tanzania and Uganda compared to Benin and Uganda which could relate to differences in the historical connectivity of forests across the continent. …”
