Deforestation associated with the initial settlement of New Zealand is a dramatic example how humans can alter landscapes through fire. However, evidence linking early human presence and land-cover change inferential in most continental sites. We employed multi-proxy approach to reconstruct anthropogenic land use Zealand's South Island over last millennium using fecal plant sterols as indicators activity monosaccharide anhydrides, polycyclic aromatic hydrocarbons, charcoal pollen tracers...
Organic molecular markers determined in a sediment core (V95-1A-1P) from Lake Victoria (East Africa) were used to reconstruct the history of human impact and regional fire activity during Early Iron Age (~2400 ~1100 yr BP). Fire was reconstructed using levoglucosan polycyclic aromatic hydrocarbons (PAHs) as for biomass burning that demonstrate two distinct periods peaking at 1450–1700 1850–2050 cal. BP. A partial correlation between PAHs is interpreted different transport behaviors burn...
Here, we present a novel fully printed electrochemical sensing tool for determining phosphorus levels in sediment samples. The integrated device is composed of an office paper-based sensor combined with customized 3D printing cube-shaped holder used the extraction from extracted was trapped on filter pad placed over and preloaded acidic ammonium molybdate, allowing formation phosphomolybdate complex, which electroactive. use carbon black as nanomodifier electrode together square wave...
Stalagmites serve as valuable archives that significantly enhance our understanding of past climate and environmental changes. The trace element records preserved within stalagmites have been used to reconstruct rainfall patterns at regional scale [1]. However, interpreting these geochemical proxies is challenging, the functioning cave system, its specific climatological geological context, must be taken into account. Comparing instrumental measurements with from grew during 20th century...
Australia has long been recognized as one of the world’s fire hotspots, but Black Summer 2019-2020, when 97,000 km2 were scorched across southeastern Australia, and larger fires northern Australia’s savanna desert in 2023, may indicate a shift toward higher level activity. Placing these events context requires developing precisely-dated, high resolution records bushfire through periods with different climate land use mean states. We reconstructed activity for period...
Understanding the long-term interactions among vegetation, fire, and climate is critical for interpreting ecosystem responses to climatic perturbations. Project Prometheus investigates Holocene paleofire dynamics, vegetation shifts, variability in Mediterranean, using speleothem records from caves Italy (Alps, Apennines, Sardinia) Balkans. By integrating multiple proxies, including polycyclic aromatic hydrocarbons (PAHs) as fire markers n-alkanes a proxy composition terrigenous input, this...
Human activity and climate change are altering natural rates intensities of wildfire, but the scale extent burning prior to modern era poorly understood. Paleofire may be reconstructed using a variety records (e.g., charcoal in lake sediments, burn scars on tree rings), these not available all environmental settings. Here we investigate utility novel paleofire proxy: trace pyrogenic organic compounds stalagmites. Polycyclic aromatic hydrocarbons (PAHs) linked biomass transported downward...
Archaeological excavations in urban and rural contexts often uncover dark homogeneous anthropogenic deposits, soils soil horizons, known as Dark Earths, Cultural Layers Anthrosols. Major scientific questions arise about the processes that lead to formation of these they are related a complex combination environmental, climatic, factors. Many studies focused on morphological physical-chemical investigation archaeological remains found well inorganic constituent soil. The organic fraction has...
A multiphase (MP) system composed of two immiscible liquids, water and isooctane, commercial 5% Ru/C as a catalyst, both with without an additional organic liquid (OL: tetrahydrofuran (THF), 2-methyl-THF, methyl isobutyl carbinol, cyclopentyl ether) was designed investigated for the chemoselective catalytic hydrogenation four model examples biobased sugars amino/amido-sugars. At 110 °C 40 bar H2, d-glucosamine hydrochloride N-acetyl-d-glucosamine were converted selectively into their...
Interest in paleoenvironmental reconstructions from biomarkers speleothems is increasing, thanks part to the capacity of grow continuously and resist postdepositional alteration. In particular, possibility exists link high-resolution accurately dated fire vegetation records with isotopic data climatic interactions at local regional scale. However, scarcity existing methods for quantification organic molecules stalagmites, together issues sample availability, contamination, low...
Cultural layers are deposits resulting from settlement and human activity on natural soil in the past. Materials past domestic activities that become buried into can be used to reconstruct impact a specific area For instance, humans have fire for millennia, charcoal soils sediments is applied as evidence of anthropic activity. In this context, assessing abundance degradation level fragments clarify cultural deposits. European towns, with similar characteristics, been defined urban "Dark...
Plant residues are the main source of organic matter in soil; this process takes place naturally forests and with amendments farmlands. Terrestrial plants also synthesize hydrocarbons. Typically, angiosperms contain hundreds to thousands milligrams long chain n-alkanes per kilogram leaf waxes. However, petroleum pollution is a worldwide issue, different national regulations set guideline limit for hydrocarbons green areas at 50 mg kg–1. Focusing on Italian legislation as case study, we...

Although about 98% of the Antarctic continent is covered by an ice sheet, seasonal lakes and small streams resulting from snow melting are formed during Austral summer. These ice-free areas, mainly located in coastal sites, provide a fertile environment for development microbial life. Isolation extreme conditions terms light, temperature nutrient availability generate peculiar ecosystems lake waters, characterized presence planktonic and/or benthonic microorganisms, especially cyanobacteria...
This research work focuses on reconstructing the anthropogenic fingerprint of past 150 years through high-resolution analysis trace organic compounds preserved in Antarctic ice. Over decades, numerous persistent and semi-volatile pollutants were largely used several industrial activities. Some them proved to be highly toxic, posing a serious threat human health natural ecosystems. Consequently, international bans agreements established reduce their production. As result, restrictions one...
Molecular biomarkers preserved in lake sediments are increasingly used to develop records of past organism occurrence. When linked with traditional paleoecological methods, analysis molecular can yield new insights into the roles herbivores and other animals long-term ecosystem dynamics. We sought determine whether fecal steroids could be reconstruct ungulate use dominant taxa a small catchment northern Yellowstone National Park. To do so, we characterized steroid profiles selection North...
