Abstract Background The global human footprint has fundamentally altered wildfire regimes, creating serious consequences for health, biodiversity, and climate. However, it remains difficult to project how long-term interactions among land use, management, climate change will affect fire behavior, representing a key knowledge gap sustainable management. We used expert assessment combine opinions about past future regimes from 99 researchers. asked quantitative qualitative assessments of the...
Ethnographic observations suggest that Indigenous peoples employed a distinct regime of frequent, low-intensity fires in the Australian landscape past. However, timing this behaviour and its ecological impact remain uncertain. Here, we present detailed analysis charcoal, including novel measure fire severity using Fourier transform infrared (FTIR) spectroscopy, at site eastern Australia spans last two glacial/interglacial transitions between 135–104 ka 18–0.5 BP (broadly equivalent to Marine...
This study examined the effects of commonly used oxidants in sedimentary macroscopic charcoal analysis on two sediment cores from Thirlmere Lakes National Park, Southeast Australia. The cores, Lake Werri Berri (WB3) and Couridjah (LC2), span ~900 years 135,000 years, respectively. Charcoal Accumulation Rate (CHAR) for both area count was quantified using four different chemical treatments compared to a control only water. We also Charring Intensity (CI) isolated fragments, proxy...
Abstract. Recent global fire activity has highlighted the importance of understanding dynamics across time and space, with records past (palaeofire) providing valuable insights to inform current future management challenges. New from recent increase in palaeofire studies Australia surrounds have not been captured any database for broader comparisons, Australasia is poorly represented international databases used modelling trends. These problems are addressed by SahulCHAR, a new collection...
This study investigated the effects a dilute solution of bleach (4% sodium hypochlorite), has on charcoal. We were particularly interested in considering if charcoal formed under different conditions pyrolysis was differentially affected by this treatment, which is commonly used for quantification sediments. first produced series samples, laboratory (at temperatures between 250°C and 800°C oxygen limited conditions) then measured total surface area before after treatment 4% bleach. found...
Abstract We present a multiproxy record using pollen, magnetic susceptibility, carbon isotopic composition, carbon/nitrogen ratio, and particle size of mid- to late Holocene environmental changes based on sediment core from the Pomaeho lagoon east coast Korea. The records indicate that climate deteriorations around 6400 cal yr BP 4000 caused rapid vegetation in study area, which were presumably attributable low sunspot activity strong El Niño–like conditions, respectively. These two cooling...
Abstract Human activity has fundamentally altered wildfire on Earth, creating serious consequences for human health, global biodiversity, and climate change. However, it remains difficult to predict fire interactions with land use, management, change, representing a knowledge gap vulnerability. We used expert assessment combine opinions about past future regimes from 98 researchers. asked quantitative qualitative assessments of the frequency, type, implications regime change beginning...
The drivers of fire regimes prior to the European occupation Australia are still contentious, with some advocating dominated by anthropogenic ignitions and others a climate source or mixture these elements. Here, we examine an 850-year history at Lake Werri Berri in south-east Australia, following occupation. Macroscopic charcoal FTIR spectroscopy were used infer broad changes regime proximity lake. We found little change through much period most interesting, no apparent initial displacement...
The vegetation structure in vast semi-arid to temperate continental land masses, particularly Australia, play a considerable role global terrestrial carbon dioxide sequestration.However, whether soil-carbon is net atmospheric source or sink remains contentious, introducing large uncertainties on long-term storage of vegetation-sequestered dioxide.We investigate the interplay between catchment erosion (quantified by means uranium isotopes), (pollen), cycling, wetland response (diatoms), and...
