Environmental changes during MIS6-3 in the Basin of Mexico: A record of fire, lake productivity history and vegetation

Response of diatom assemblages to orbital‐ and millennial‐scale climatic variability since the penultimate glacial maximum in the northern limit of the Neotropics

“…Therefore in the discussion as well as in Figures 6-8, and in Table 2, the MIS terminology is used, as it is interchangeable with the diatom zones. Therefore, the MIS boundaries could be different from those used in previous studies in Chalco (Ortega-Guerrero et al 2017, 2020, Martínez-Abarca et al 2021a, Chávez-Lara et al 2022a.…”

“…Several sediment sequences from ancient Lake Chalco have been collected near the depocenter of the lake. In this paper, we present the detailed diatom record of the CHA08 sequence from 17.5 to 122.4 m. Note, however, that in previous works the CHA08 sequence was integrated with the CHA11-VII core, which covers the uppermost 18 m to produce a master sequence from which facies analysis, geochemical, magnetic mineralogy, summary diatom groups and charcoal records have been published previously (Torres-Rodríguez et al 2015, Ortega-Guerrero et al 2017, 2020, Martínez-Abarca et al 2021a. In this work, nevertheless, we present the CHA08 sequence and the previously published diatom data from the 26-m-long Cha-B core (Caballero & 6) Lake Fúquene, Venezuela (Groot et al 2011); (7) Lake Titicaca, Peru/ Bolivia (Fritz et al 2007(Fritz et al , 2012 Ortega- Guerrero 1998.…”

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

“…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).…”

Evidence for stages of landscape evolution in Central Mexico during the late Quaternary from paleosol-pedosediment sequences

“…In recent decades extensive paleoenvironmental reconstruction has been undertaken in Central Mexico. Most of these studies have been based on lacustrine (Caballero et al, 1999; Torres-Rodríguez et al, 2015; Brown et al, 2019; Martínez-Abarca et al, 2021), glacial (White, 1962; Heine, 1984; Vázquez-Selem and Heine, 2004, 2011), fluvial (Borejsza and Frederick, 2010), or soil (Sedov et al, 2001, 2009; Solleiro-Rebolledo et al, 2004, 2006; Sycheva et al, 2013; Sánchez-Pérez et al, 2013) sedimentary records. Lacustrine sediments reveal the history of closed basins and lower landscape positions, whereas glaciers are limited to the highest volcanic elevations.…”
