  • The timing and ecological consequences of Pleistocene megafaunal decline in the eastern Andes of Colombia

    Open AccessFelix Pym, Felipe Franco-Gaviria et al.ARTICLEQuaternary Research2023

    Examining the ecological consequences of the late Quaternary megafaunal extinctions within biodiversity hotspots is crucial for our understanding of the potential consequences of contemporary extinctions. We present the first multi-species record of spores of coprophilous fungi (SCF) from Monquentiva and the high-Andean forests of Colombia to reconstruct Late Pleistocene and Holocene megafaunal abundance. Fossilised pollen and charcoal are used t…

  • Mangrove diversity loss under sea-level rise triggered by bio-morphodynamic feedbacks and anthropogenic pressures

    Open AccessDanghan Xie, Christian Schwarz et al.ARTICLEEnvironmental Research Letters2020

    Mangrove forests are valuable ecosystems, but their extent and diversity are increasingly threatened by sea-level rise and anthropogenic pressures. Here we develop a bio-morphodynamic model that captures the interaction between multiple mangrove species and hydro-sedimentary processes across a dynamic coastal profile. Numerical experiments are conducted to elucidate the response of mangrove assemblages under a range of sea-level rise and sediment…

  • Modern pollen-vegetation relationships along a steep temperature gradient in the Tropical Andes of Ecuador

    Open AccessKimberley Hagemans, Claudia-Dana Tóth et al.ARTICLEQuaternary Research2019

    The characterization of modern pollen rain assemblages along environmental gradients is an essential prerequisite for reliable interpretations of fossil pollen records. In this study, we identify pollen-vegetation relationships using modern pollen rain assemblages in moss polsters (n = 13) and lake sediment surface samples (n = 11) along a steep temperature gradient of 7°C (3100–4200 m above sea level) on the western Andean Cordillera, Ecuador. T…

  • Vegetation responses to late Holocene climate changes in an Andean forest

    Open AccessJacob D Schiferl, Mark B Bush et al.ARTICLEQuaternary Research2018

    A paleoecological record from Lake Palotoa (1370 m elevation) in the Andean foothills of Peru spans the last 3800 years. Lake Palotoa lies near the modern cloud base in a location sensitive to changes in atmospheric moisture. In many areas, these forests have been destroyed, but Lake Palotoa shows no sign of human occupation today or in the past. The modern forest surrounding the lake is dominated by the Andean palm, Dictyocaryum lamarckianum , w…

  • Vegetation and environmental changes at the Middle Stone Age site of Wonderkrater, Limpopo, South Africa

    Open AccessElysandre Puech, Dunia H Urrego et al.ARTICLEQuaternary Research2017

    Wonderkrater, a Middle Stone Age site in the interior of South Africa, is a spring and peat mound featuring both paleoclimatic and archaeological records. The site preserves three small MSA lithic assemblages with age estimates of 30 ka, >45 ka and 138.01±7.7 ka. Here we present results of the pollen analysis of a core retrieved from the middle of the peat mound, which covers, with hiatuses, the timespan between ca. 70±10 ka and 30 ka. Pollen per…

  • Holocene land–sea climatic links on the equatorial Pacific coast (Bay of Guayaquil, Ecuador)

    Open AccessBrice Seillès, Marı́a Fernanda Sánchez Goñi et al.ARTICLEThe Holocene2015Referencias: 4

    We analyzed the pollen content of a marine core located near the Bay of Guayaquil in Ecuador to document the link between sea surface temperatures (SSTs) and changes in rainfall regimes on the adjacent continent during the Holocene. Based on the expansion/regression of five vegetation types, we observe three successive climatic patterns. In the first phase, between 11,700 and 7700 cal. yr BP, the presence of a cloud (Andean) forest in the mid alt…

  • A long history of cloud and forest migration from Lake Consuelo, Peru

    Open AccessDunia H Urrego, Mark B Bush et al.ARTICLEQuaternary Research2010

    The complete paleoecological history from Lake Consuelo forest yields a record of ground-level cloud formation and changes in its lower altitudinal limit over the last 46,300"cal yr BP. The timing of early lake level fluctuations prior to 37,000"cal yr BP appears sensitive to North Atlantic temperature oscillations, corresponding to Dansgaard"Oeschger interstadials 11, 10 and 8 recorded in GISP2. After the LGM, the first hint of warming is record…
