Showing papers in "Anthropocene in 2021"

TL;DR: In this paper, the authors examined interactions between human and natural systems that result in ecosystem services and changes in land use and land cover in urban areas, and developed a social-ecological model to address urban challenges with nature-based approaches.

TL;DR: In this paper, the authors investigated the land transitions in these products and explored the effects on two key environmental aspects, namely, carbon losses from deforestation and soil erosion rates, and identified land transitions and changes in key environmental processes reflect a humandominated Earth system and the indirect effects of climate change on land cover, especially in boreal ecosystems.

TL;DR: The Birds of Paradise wetland in Belize has been studied in this paper, where the authors demonstrate that ancient Mayan farmers managed riparian wetlands in northwestern Belize to a much greater spatial extent than previous estimates.

TL;DR: In this article, a review synthesizes the bodies of literature on the archaeology, ecology, land use history, environmental change and development planning in the Karoo region, addressing the effects of historical land use on biodiversity and ecosystem goods and services in the region.

TL;DR: In this article, an analysis of two pollen records from both sides of the Sierra Nevada, the prime plant-diversity centre of the Mediterranean, spanning the last 5400 years is presented.

TL;DR: In this article, the authors employ a literature review and qualitative analysis of the interview data, enabling them to draw out key themes of local versus global discourses on the current management and future prospects of these peatland ecosystems.

TL;DR: In this paper, the authors present a twenty-year analysis into the vegetation of a closed municipal solid waste landfill in Poland using the method of phytocoenological releves, which indicated differences in the representation of native plant species and neophytes in the composition of vegetation.

TL;DR: Wang et al. as discussed by the authors presented new archaeobotanical and geological evidence of early rice domestication in the Yaojiang Valley from a well-dated sediment core retrieved near the Jingtoushan site, the earliest shell mound discovered in eastern coastal China.

TL;DR: In this article, the authors analyzed the evolution of hydrological and climatic drought in headwater catchments of Spain and explored the extent to which vegetation can reinforce trends in hydrologogical drought severity.

TL;DR: In this paper, the authors examined the discourses on dams within the public domain, using a collection of newspaper articles published in Le Monde from 1945 to 2019 on dams that were planned and built throughout the world.

TL;DR: In this article, the authors investigated the role of agricultural practices during the second half of the 20th century in accelerating soil erosion around the world, using a combination of monitoring or modelling at short timescales.

TL;DR: In this paper, the authors examined Hawaiian wetland agro-ecosystems (loʻi) as social-ecological systems that may meet human needs while expanding nesting habitat of endangered waterbirds, if restored under an Indigenous Resource Management paradigm.

TL;DR: In this article, the authors developed a new dynamic model, LUCCA (Land Use Change & Conversion Accounting) that robustly quantifies the dynamics of carbon stocks and fluxes.

TL;DR: In this article, the authors review and synthesize literature relevant to process-based approaches to restoration ecology that incorporate a long-term perspective, identifying alternative descriptors to frame reference conditions, useful theoretical principles for restoration ecology, and a management decision-support framework based on these principles.

TL;DR: The authors examined diatom records from sediment cores from paleoclimate studies in mountain lakes of Guatemala, Panama, and Colombia, in order to clarify the long-term human influences on the ecology of these lakes.

TL;DR: In this article, the authors report a sequence of constructed and removed pond dams along the Vrchlice River, Czechia, and their use as sedimentary archives, in order to reconstruct the long-term (>200 yr) history of contamination.

TL;DR: Using a conservation paleobiology approach, the authors established biological baselines and assessed the effects of natural and anthropogenic environmental change on benthic communities in an urbanized subtropical seascape.

TL;DR: In this paper, the use of plastic particles as a new stratigraphic marker within fluvial systems of the "Anthropocene" and thus for dating the youngest sedimentary deposits is discussed.

TL;DR: In this article, the occurrence of regime shifts to track changes throughout the lake food web beyond the typical instrumental era, using both traditional paleoecological proxies (e.g., cladoceran zooplankton, zoobenthos, and pigments) and more recently developed molecular genetic methods based on sedimentary DNA.

TL;DR: In this article, the authors measured trace metals in archived lichen and fungi samples, dating back over 158 years, to ascertain their potential to record temporal shifts in atmospheric source inputs, starting from the onset of industrial activity in Australia to the present.

TL;DR: In this article, the authors developed a system breakdown accounting method to assess the urban carbon cycle, which facilitates greater understanding of the complex interactions within and between systems involved in this cycle, in order to identify ways in which humans can adapt their interactions to reduce net greenhouse gas emissions from urban regions.

TL;DR: In this paper, a conceptual model of changes in potential runoff and sediment supply over a series of construction phases suggests that potential sediment supply peaks with bare soil cover, but then remains high during subsequent road and house construction as imperviousness and drainage connection increase.

TL;DR: The first evidence for metallurgy is found during the apogee of the Tiwanaku state (AD 800-1150), with a higher copper (Cu) accumulation that can be attributed to the smelting of local Cu ores, based on Pb isotopic fingerprinting.

TL;DR: In this article, the authors applied the N14CP model, an integrated soil-plant biogeochemistry carbon-nitrogen-phosphorus model, across the United Kingdom to simulate changes in terrestrial carbon storage from 1700 to 2020.

TL;DR: Wang et al. as mentioned in this paper examined the impacts of the temporal and spatial changes in rainfall on flood risks in traffic systems in the Yangtze River Delta in China and constructed a framework for assessing flood risk in the arterial traffic system under changing rainfall regimes.

TL;DR: In this paper, the authors used robust regression and robust principal component analysis, using a log-ratio methodology of compositional data analysis, which is a fast and effective tool in assessing contamination levels.

TL;DR: In this article, the authors present a record of atmospheric Pb deposition from an ombrotrophic peat bog at Furamoos, southern Germany, and combine Pb content and isotope data with pollen data allowing the interpretation of Pb signals within a context of natural change and human activities.

TL;DR: In this article, the authors used well-adapted statistical models to explain variations in two state indicators, two pressure indicators, and one response indicator representing biodiversity, focusing on the relative efficiency of various indicators of human activity (notably human population density, human appropriation of net primary productivity, and gross domestic product per area) in predicting the biodiversity indicators.

TL;DR: In this paper, the authors integrated sedimentological, paleobotanical, and radiometric analyses of sediment cores collected in 2018 with analyses of aerial photography taken between 1940 and 1997.
