Intensified fire activity induced by aridification facilitated Late Miocene C4 plant expansion in the northeastern Tibetan Plateau, China

Mid–Miocene Palaeofire and Its Complex Relationship With Vegetation Changes in the Wushan Basin, Northeastern Tibetan Plateau, China: Evidence From a High–Resolution Charcoal Record

“…Therefore, the ratios of CC R /CC L can be directly used to indicate the relative wood/grass ratios during the combustion (Miao et al., 2019). We interpret microscopic charcoal in the samples to represent regional sources and macroscopic charcoal to indicate local sources (Crawford & Belcher, 2014; Hui et al., 2021; Leys et al., 2015).…”

“…To date, most studies of fire history focus on the linkages between fire and climate changes on orbital to millennial timescales and the relationship between human activities and fire regimes (Daniau et al., 2010; Finsinger et al., 2017; Inoue et al., 2018; Kappenberg et al., 2019, 2021; Li & Wang, 2020; Martínez–Abarca et al., 2021; Power et al., 2012; Shi et al., 2020; Tan et al., 2021; Thevenon et al., 2004; Verardo & Ruddiman, 1996; Walsh et al., 2008; Wang, Ding, & Peng, 2012, 2013). By contrast, very few pre–Quaternary high–resolution fire records are available to assess natural fire variability on tectonic to orbital timescales (Hoetzel et al., 2013; Hollaar et al., 2021; Zhang et al., 2020), especially in the inland of Asia (Hui et al., 2021; Miao et al., 2016, 2019). In addition, previous studies have improved our knowledge of fire history over multiple timescales of Earth' history by investigating its controlling factors and possible driving forces such as vegetation characteristics, dry/wet or cold/warm climate, O 2 and CO 2 concentration, rainfall seasonality, Earth's orbital forcing and solar radiation etc.…”

“…(Daniau et al., 2010; MacDonald et al., 1991; Millspaugh & Whitlock, 1995). Among these fire proxies, sedimentary charcoal, a carbonaceous material produced by heating of biomass during incomplete combustion (Patterson et al., 1987; Whitlock & Larsen, 2002), has been widely used in paleoenvironmental studies as an indicator of fire activity across multiple timescales (e.g., Hoetzel et al., 2013; Hui et al., 2021; Li & Wang, 2020; MacDonald et al., 1991; Miao et al., 2016, 2019; Moore et al., 2022; Patterson et al., 1987; Power et al., 2006; Shi et al., 2020; Whitlock & Larsen, 2002).…”

Charcoal in Kunlun Mountains loess: Implications for environment change and human activity during the middle Holocene

“…A higher charcoal concentration generally corresponds to more intense and frequent wildfires. Wildfire activity is related to both climatic changes and human activities (Goldberg, 1985;Clark, 1988;Hui et al, 2021).…”

Early Oligocene—Late Miocene Wildfire History in the Northern Tibetan Plateau and Links to Temperature-Driven Precipitation Changes

“…Charred grains from southern Africa have also been used as a wildfire proxy but showing that wildfire reached a maximum at 7-6 Ma ago under moderately dry conditions (Hoetzel et al, 2013). Similarly, wildfire and its potential links with monsoonal precipitation have been studied in inner Asia for the past 7 Ma (Zhou et al, 2014) or 16 Ma (Hui et al, 2021). Wildfire patterns in East Asia have changed during the last 13 Ma, possibly influenced by regional hydroclimatic changes (Shen et al, 2018).…”
