It is necessary to explore the relationships among human, environment and ecosystem in a global change context. Ombrotrophic peatlands are precipitation-dependent and derive nutrients solely from atmospheric deposition, which can document environmental changes continuously. Diatoms preserved in peat sediments are abundant and diverse, and sensitive to hydrological environment changes. Here we reconstructed the historical water table conditions based on diatom from an ombrotrophic peatland in the northern Greater Khingan Mountains, and to assess the influence of climate and human on ecosystem development over the past 150 years. Our results revealed the hydrological condition in Hongtu (HT) peatland was mainly impacted by climate before 1950 AD. HT peatland remained in a pristine state with minimal human interference, as native inhabitants continued to hunt and gather. After the New China was established in 1949 AD, high frequency of fire events caused by rapid population growth, mining and industry destroyed the diatom diversity. Higher water table in HT peatland from 1950 AD to 1965 AD was resulted by higher rainfall. Since 1980 AD, especially after 2000 AD, a suddenly increase of tolerant diatoms species (<em>Achnanthidium minutissimum</em> and <em>Craticula molestiformis</em>) indicated enhanced anthropogenic disturbance. Anthropogenic emissions caused by industrial production and coal consumption increased the atmospheric nitrogen deposition. The abnormal drought of HT peatland was influenced by both climate warming and human activities since 1980s. The recent and strong effects of human activities on peatlands left significantly stratigraphic signals of the Anthropocene in peat deposits. Diatoms have potential to be applied as indicators of long-term hydrological changes in ombrotrophic peatlands, as they are highly sensitive to environmental changes and human disturbance.</div></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"50 ","pages":"Article 100473"},"PeriodicalIF":3.3,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143833572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, we hypothesise that water bodies associated with traditional pastoralist practices, such as those along drove roads used for transhumance (<em>e.g.</em> ponds and troughs), may play a crucial role in supporting amphibian assemblages. Conducted in one of the main drove roads still in use in Spain (the Conquense Drove Road, hereafter CDR), this study evaluated the conservation condition and contribution of the CDR water bodies to amphibian breeding assemblages at a landscape scale. We also explored the influence of landscape (land use cover) and local (water body characteristics) variables on the occurrence of breeding amphibians within and outside the CDR. Results confirm that the CDR provides a significantly higher proportion of functional water bodies to the landscape compared to its surroundings, providing highly valuable refuges for amphibians against threats caused by land use intensification. This key function of the CDR in the maintenance of amphibian breeding points persists despite the observed lack of continuity of water bodies along its route.

Here, magnetic parameters were measured in a dated sediment core from Lake Chaohu, Anhui Province, China, to explore whether and to what extent environmental magnetism proxies indicate the complex human activities in the lake basin over the past 166 years. Results demonstrate that detrital magnetite minerals were the major magnetite fraction in the sediments. The lowest values of magnetic concentration proxies (χ<sub>lf</sub>, χ<sub>ARM</sub>, and SIRM) in sediments prior to approximately 1950 indicate minimal input of detrital magnetic minerals, implying limited disturbance of the catchment, which coincided with weak human activities in the lake basin in this period—mainly primitive agriculture. In sediments deposited during ca. 1950–1985, increased χ<sub>lf</sub> and reduced grain size-dependent proxies (χ<sub>fd</sub>%, SIRM/χ<sub>lf</sub>, and χ<sub>ARM</sub>/χ<sub>lf</sub>) indicate increased input of detrital magnetic minerals and coarsening of the magnetic grains. This shift might have resulted from the rapid development of agricultural and industrial activities in the lake catchment since the 1950s and decreased hydrodynamic force within the lake due to dam construction in the 1960s. After ca. 1985, χ<sub>lf</sub>, χ<sub>ARM</sub>, and SIRM gradually decrease to the pre-1950 levels, indicating further decrease of the magnetic mineral input. This is likely due to decreased agricultural activities as a consequence of urbanization expansion and a shift from high pollution factories to high-tech industry.

To explore these aspects, trace metals, major elements, and lead (Pb) isotope ratios were analyzed in an 8000-year sediment records from Lake Accesa, a karst lake located on the southern border of the Colline Metallifere mining district. The findings indicate that Pb in Lake Accesa is mainly related to sulfide polymetallic deposits that surround the lake catchment. The first signal of Pb pollution dates to about 3300 BCE (Before Common Era) during the Copper Age and it is consistent with the archaeological evidence of Southern Tuscany. Additional human-induced Pb pollution signals can be observed in the Bronze Age (∼1550 BCE), and a long phase beginning in the Middle Ages (from ∼700 CE[Common Era]). Between 1000 and 1700 CE, Pb reached the highest concentrations, corroborating the intensity of mining activity during and after the Medieval period. These findings reveal that pre-industrial activities left a significant legacy of potential toxic elements in the environment, resulting in pollution levels that exceed those related to recent activities associated with the Anthropocene.
