In this multi-proxy palaeo study, the response of primary producers and consumers to anthropogenic disturbances in a large shallow lake was investigated. Overall, eutrophication water-level changes (partly inferred by bisaccate pollen grains) are well-reflected sedimentation rates pigments, diatom cladoceran species composition other proxies (e.g. Rhabdocoela oocytes). particular, stepwise decrease relative abundance Pediastrum simplex compared P. boryanum/P. duplex proved be good indicator...
Phosphorus (P) is critical for food production. However, it has been managed unsustainably decades and geopolitical challenges complicate its availability. While accessible P-rock deposits are linearly exploited, excessive fertilization practices lead to P loss from land water, thus, eutrophication. The release of legacy sediments the water column, i.e. internal loading, sustains global eutrophication issues. Sediment removal subsequent reuse as soil amendment can simultaneously lower...
Abstract This paleolimnological study aims to investigate how natural processes and anthropogenic land‐use changes have affected sedimentary phosphorus (P) forms primary producers in a small, temperate lake (Lake Fuglsø, Denmark) throughout the Holocene. Our multi‐proxy approach uses pollen, X‐ray fluorescence scanning, carbon (C) nitrogen contents stable isotopes, sequential P extraction, 31 nuclear magnetic resonance spectroscopy, pigments, diatoms, plant macrofossils from 14 C‐dated...
Abstract Mountain ecosystems are sensitive to environmental changes and affected by direct indirect anthropogenic activities. This study sought understand the impacts of human occupation, climate change on Great Hinggan Mountains (GHM) in Northeastern China. The last 200 years reconstructed analyzing sediment cores from five small mountain lakes. Cores were dated using 210 Pb 137 Cs radioisotopes, microscopic charcoal identified regional fire activity fossil pollen analysis temporal spatial...
Abstract Diffusive equilibrium in thin films (DET) probes are passive samplers that designed to reflect situ porewater concentrations. In this study, we show the gel and plastic housing of DET store a substantial amount oxygen (O 2 ) affects chemical composition porewater. To ensure complete deoxygenation, need be treated for 7 d with continuous nitrogen flow. Such fully deoxygenated can handled air (exposure time: < 90 s) deployed sediments through oxic water without significant...
