61 Maezumi, Shira YoshimiNeotropical climate, vegetation, and fire histories on local to regional scalesDuring the 21st century global change and deforestation have increased fires in the Amazon. Protection of rainforests and sustainable land-use practices in the Neotropics are critical for preserving biodiversity and buffering for climate. To make informed policy decisions it is necessary to understa...Amazon; Bolivia; Paleoecology; Paleofire; Phytoliths; Pollen2015-05
62 Graves, Scott AndrewExamining vegetation phenology of Ugandan dambos using spectral mixture modeling fractionsOrganic Matter (SOM). Lacking O2, micro-organisms decompose SOM through anaerobic decomposition, which in turn produces CH4. Because wetland soils are continually saturated, the organic matter is decomposed primarily by anaerobic means, which makes wetlands the primary source of naturally produce...Vegetation mapping, Uganda;Wetland ecology, Uganda; Methane, Environmental aspects, Uganda2008-05
63 Turrin, James BradleyMeasuring glacier velocities on the Kenai Peninsula, Alaska, using multispectral satellite imagery with feature trackingPrevious studies have shown that the glaciers of southern Alaska are receding and thinning, and contributing significantly to sea-level rise, and that temperate glaciers are sensitive indicators of climate change. Therefore, a method is developed to apply feature tracking software to moderate res...Glaciers--Alaska; Glaciology; Aerial photography2010-03-20
64 Turney, Lovina AbbottHolocene climate, vegetation, and fire linkages in the Uinta Mountains, UtahA 14,000-year lake sediment record from Heller Lake-Dry Gulch Meadow on the south slope of the Uinta Mountains provides evidence of large-magnitude disturbance events during the Holocene. The modern lake basin which catastrophically drained in the early 20th century provides a uniquely exposed sedim...Charcoal; Climate; Holocene; Pollen2014-12
65 Baskin, Robert LeRoyOccurrence and spatial distribution of microbial bioherms in Great Salt Lake, UtahMicrobial bioherms constitute some of the earliest forms of life on Earth. Although the primary form of life on earth during the Proterozoic (Hoffman, 1994), modern occurrences that spread over an area greater than a few square kilometers are rare. Microbial bioherms in Great Salt Lake were reported...Distribution; Great Salt Lake; Microbial bioherm; Microbialite; Stromatolite; Thrombolite2014-12
66 Howard, Kelsey AnnA late pleistocene to early holocene climate, vegetation and fire history record for the bonneville basin, utah, usaThe Bonneville basin of northwestern Utah acts as a significant source of paleoenvironmental data due to the sedimentary and geomorphic evidence left behind from the late Pleistocene Lake Bonneville.
