Late Holocene tephrostratigraphy from Cajas National Park, southern Ecuador

Management Policy for Podocarpus National Park, Ecuador: A Synthesis

National Parks have been created around the world to safeguard biodiversity, ecosystem services, recreational opportunities, cultural heritage, and many other worthy objectives. While we strive to achieve these resource-oriented goals, long-term success will not be realized without finding common ground between the people who live, work, visit, or otherwise have an interest in these regions. Se...

Early Holocene Archeology in Grand Teton National Park

Late-glacial and Holocene vegetational history from two sites in the western Cordillera of southwestern Ecuador

The deciphering of the late-glacial and Holocene vegetation, glacial-geological, and climatic history of Cajas National Park in southwestern Ecuador is undertaken focusing on close-interval sampling of sediment cores from two high elevations lakes, Lagunas Chorreras (3700 m) and Pallcacocha (4060 m). This study involves extensive dating (both accelerator mass spectrometry and tephra), palynolog...

Late Weichselian and Holocene palaeoceanography of Storfjordrenna, southern Svalbard

Multiproxy analyses (including benthic and planktonic foraminifera, δO and δC records, grain-size distribution, ice-rafted debris, XRF geochemistry and magnetic susceptibility) were performed on a C-dated marine sediment core from Storfjordrenna, located off of southern Svalbard. The sediments in the core cover the termination of Bølling–Allerød, the Younger Dryas and the Holocene and reflect g...

A diatom record of late Holocene climate variation in the northern range of Yellowstone National Park, USA

The changes in diatom species composition in a sediment core from Crevice Lake, Yellowstone National Park, spanning the past 2550 yr, were used to reconstruct long-term limnological and ecological conditions that may be related to late Holocene climate variability. Planktic forms dominate the fossil diatom assemblages throughout this record, but changes in species dominance indicate varying nut...
