• Ecology and paleoenvironmental application of testate amoebae in peatlands of the high-elevation Colombian páramo

  Open Access•Bing Liu, Robert K Booth et al.•ARTICLE•Quaternary Research•2019

  Incluir item

  We investigated the ecology and paleoecology of testate amoebae in peatlands of the Colombian páramo to assess the use of testate amoebae as paleoenvironmental indicators. Objectives were to (1) identify environmental controls on testate amoebae, (2) develop transfer functions for paleoenvironmental inference, and (3) examine testate amoebae in a Holocene peat core and compare our findings with other proxy records. Results from 96 modern samples …

• Paleoclimate support for a persistent dry island effect in the Colombian Andes during the last 4700 years

  Incluir item

  We investigated middle- and late-Holocene hydroclimate patterns in the Colombian Andes using indicators of watershed erosion (lithic abundance), precipitation intensity (% silt), lake-level variability (organic carbon and nitrogen, % sand, and diatoms), and fire frequency (fossil charcoal) from a ~4700-year-long sediment archive from Laguna de Ubaque, a small sub-alpine lake on the eastern flank of the eastern Colombian Andes. Our results indicat…

• Environmental and cultural changes in highland Guatemala inferred from Lake Amatitlán sediments

  Open Access•Maria I Velez, Jason H Curtis et al.•ARTICLE•Geoarchaeology•2011•Citada por: 10•Referências: 6

  Incluir item

  We inferred the late Holocene environmental history of the Guatemala highlands from multiple lines of evidence in a sediment core from Lake Amatitlán. Inferred environmental changes are generally synchronous with archaeologically documented highland Maya cultural shifts. Population increases in the Middle Preclassic, Early Classic, and Late Postclassic are associated with deforestation and soil erosion. Land abandonment in the Late Preclassic, La…
