Anthropogenic drivers accelerate the changes of lake microbial eukaryotic communities over the past 160 years Quat. Sci. Rev. (IF 4.0) Pub Date : 2024-02-07 Dongna Yan, Yongming Han, Zhisheng An, Dewen Lei, Xue Zhao, Haiyan Zhao, Jinzhao Liu, Eric Capo
Human impacts on Earth's atmosphere, hydrosphere, litosphere and biosphere are so significant as to naming a new geological epoch, the Anthropocene. Lakes and their biota are highly sensitive to environmental changes. Among aquatic organisms, microbial eukaryotes play fundamental roles associated with lake ecosystem functioning, food webs, nutrient cycling, and pollutant degradation. However, the response

Method development and application of object detection and classification to Quaternary fossil pollen sequences Quat. Sci. Rev. (IF 4.0) Pub Date : 2024-02-06 Robin von Allmen, Sandra O. Brugger, Kai D. Schleicher, Fabian Rey, Erika Gobet, Colin J. Courtney Mustaphi, Willy Tinner, Oliver Heiri
The automation of fossil pollen analysis promises many advantages in handling large numbers of samples with less resource allocation. However, automation is often obstructed by the high abundance of organic and minerogenic non-pollen debris in fossil pollen samples. We used a Convolutional Neural Network-based approach to detect pollen-like objects in digital images of prepared microscopic slides for

Holocene coastal environmental evolution and human adaptation in the Yaojiang-Ningfeng plain, eastern China, revealed by reanalysis of the radiocarbon dates Quat. Sci. Rev. (IF 4.0) Pub Date : 2024-02-05 Konglan Shao, Huayu Lu, Hongyan Zhang
The Yaojiang-Ningfeng coastal plain attracted widespread attention since this region is the core area of the flourishing Neolithic Hemudu Culture and rice domestication. However, the availability of accurate deposited ages of sediments from this region are always difficult due to dating anomalies. One of the possible reasons is that previous studies mainly used the radiocarbon (C) dates from one to

Reevaluating the Little Ice Age: Novel insights from oceanic and terrestrial records on unexpected warm winters Quat. Sci. Rev. (IF 4.0) Pub Date : 2024-02-02 Huimin Guo, Wenfeng Deng, Xuefei Chen, Jian-xin Zhao, Gangjian Wei
This investigation into the Little Ice Age (LIA) climate discrepancies explores sea surface temperature (SST) anomalies in the South China Sea (SCS) using monthly resolved coral Sr/Ca proxies. Results show that, during the LIA, while overall summer and annual SSTs were cooler compared to the Medieval Climate Anomaly and the Current Warm Period, winters were unexpectedly warmer. This warming is corroborated

Wet and dry events influenced colonization of a mid-elevation Andean forest Quat. Sci. Rev. (IF 4.0) Pub Date : 2024-02-02 R.A. Sales, C.N.H. McMichael, L.C. Peterson, A. Stanley, I. Bennett, T.E. Jones, A.S. Walker, M. Mulhearn, A. Nelson, C. Moore, M. O'Connor, W. Sinkler, C. Banner, W. Church, P. VanValkenburgh, M.B. Bush
Few paleoecological records are available to document the history of mid-elevation montane forests in the tropical Andes between 1500 and 2500 m above sea level. Archaeological studies have identified late-Holocene human modification of these landscapes, but it is not clear when and to what degree such alteration began. Here, we report fossil pollen, X-ray fluorescence, and charcoal data from Lake

Holocene vegetation dynamics, carbon deposition, sea level changes, and human impact inferred from the Lagoa da Fazenda core in the Baía de Caxiuanã region, Northern Brazil Quat. Sci. Rev. (IF 4.0) Pub Date : 2024-02-02 B. Wang, M.L. Costa, G.J.S.S. Valente, P.H.C. Santos, H. Behling
Tropical peat deposits as a potential carbon (C) stock are important to global climate change. Hence, it is necessary to explore the mechanism of formation and dynamics of tropical peat ecosystems. Up to present, the paleoecology of peat ecosystems in eastern Amazonia is still little known. We did a multi-proxy analysis including pollen and spores, LOI, organic C, macro-charcoal, minerals and chemical

Stable carbon isotope composition of land snail shells in Westerlies Asia and monsoonal Asia: paleoclimate implications Quat. Sci. Rev. (IF 4.0) Pub Date : 2024-01-31 Mi Wang, Xin Wang, David L. Dettman, Qiang Wang, Donghao Wu, Weiguo Liu, Farhad Khomali, Junsheng Nie, Naiqin Wu, Fahu Chen
Paleoclimatic records of sub-annual to interannual resolution are valuable for the study of climatic forcing mechanisms but these records are rare in terrestrial settings. Here, we show that high-resolution stable carbon isotope data within shells of land snails (δC) living in a C plant-dominated community can be an indicator of growing season precipitation (GSP) amount. We collected modern land snails
