Woolly mammoths in mainland Alaska overlapped with the region's first people for at least a millennium. However, it is unclear how used space shared people. Here, we use detailed isotopic analyses of female mammoth tusk found 14,000-year-old archaeological site to show that she moved ~1000 kilometers from northwestern Canada inhabit an area highest density early sites interior until her death. DNA and other local contemporaneous remains revealed multiple herds congregated this region. Early Alaskans seem have structured their settlements partly based on prevalence made raw materials likely food.

Abstract Worldwide, large wildfires are becoming increasingly common, leading to economic damages and threatening ecosystems human health. Under future climate change, more frequent fire disturbance may push into non‐forested alternative stable states. Fire‐prone such as those in the Mediterranean Basin expected be particularly vulnerable, but position of tipping points is unclear. We compare long‐term palaeoecological data from Sardinia with output a process‐based dynamic vegetation model investigate mechanisms controlling complex interactions between fire, climate, past future. Our results show that changes Erica ‐shrublands mixed evergreen‐broadleaved Quercus ilex ‐dominated forests were driven by climate‐induced regime shift. By simulating dynamics under varying regimes, we could reproduce Holocene trajectories mechanistically identify points. Without an immediate reduction greenhouse gas emissions, simulate expansion fire‐prone maquis increasing occurrence. Similarly, high anthropogenic ignition frequencies plantations non‐native, highly flammable trees induce shift fire‐adapted shrublands.

The influence of paleoclimate in shaping current biodiversity pattern is widely acknowledged. However, it remains unclear how the upper paleo-range limit trees, which dictated habitat endemic alpine species, affects variability species composition across space over Tibetan Plateau. We integrated satellite-derived range dendrochronological data, and fossil pollen records with a dataset climate-driven predictive model to reconstruct spatio-temporal trees at 100-year intervals since Last Glacial Maximum. Our results show that distributed lowest elevations during Maximum (~3426 m), ascended highest Holocene Climatic Optimum (~4187 level ~180 m higher than present-day (~4009 m). temporal fluctuations limits play more important role spatial beta-diversity flora, regions witnessing having lower beta-diversity. therefore suggest anthropogenic-caused climate change on decadal-to-centennial timescales could lead orbitally-forced centennial-to-millennium timescales, consequently cause homogenization composition, threatening pool.

In combination with glacial-interglacial cycles of Pleistocene, species an integral part control regimes that shaped flora and fauna. With human-facilitated extinction elephant, these landscape-forming processes were lost during last Glacial-Interglacial cycle. Given today’s climate, could elephants still be modern ecosystems in Europe? And if yes, where? Answers to questions can support nature conservation preserving historically adapted regimes.

Abstract Changing climates in the past affected both human and faunal population distributions, thereby structuring diets, demography, cultural evolution. Yet, separating effects of climate-driven human-induced changes prey species abundances remains challenging, particularly during Late Upper Paleolithic, a period marked by rapid climate change ecosystem transformation. To disentangle hunter-gatherer populations on animal period, we synthesize disparate paleoclimate records, zooarchaeological data, archaeological data using ecological methods theory to test what extent anthropogenic impacts drove broad subsistence observed Paleolithic records. We find that assemblages European are consistent with habitat shifts impacting natural high-ranked landscape rather than resource depression. The study has important implications for understanding how impacted structured diet demography can serve as baseline considerations resilience adaptation present.

Summary Infectious diseases have had devastating impacts on human populations throughout history. Still, the origins and past dynamics of pathogens remain poorly understood 1 . To create first spatiotemporal map diverse ancient microorganisms parasites, we screened shotgun sequencing data from 1,313 remains covering 35,000 years Eurasian history for DNA deriving bacteria, viruses, parasites. We demonstrate widespread presence microbial in remains, identifying over 2,400 individual species hits 896 samples. report a wide range detected time including food-borne Yersinia enterocolitica Shigella spp., animal-borne Leptospira interrogans , malaria-causing parasite Plasmodium vivax Our findings extend previously described such as pestis causative agent plague, Hepatitis B virus Borrelia recurrentis cause louse-borne relapsing fever (LBRF).

A series of abrupt climate events linked to circum-North Atlantic meltwater forcing have been recognised in Holocene paleoclimate data. To address the paucity proxy records able characterise robustly regional impacts these events, we retrieved a sub-centennial resolution, well-dated core sequence from Lake Kuutsjärvi, northeast Finland. By analysing range paleo-environmental proxies (pollen, plant sedimentary ancient DNA, macrofossils, conifer stomata, and non-pollen palynomorphs), supported with proxy-based paleotemperature moisture reconstructions, unravel well-defined vegetation dynamics over early-to-middle Holocene.
