  • C 14 dating ; Colluvium ; Colorado ; Dendrochronology ; Flood ; Geochronology ; Quaternary ; United States ; Watershed
  • The AA. present evidence for multiple late Quaternary paleofloods in Arthurs Rock Gulch, a small ephemeral drainage basin in the Colorado Front Range foothills near Fort Collins, Colorado; and describe their approach to paleoflood retrodiction
  • Al sur del rio Colorado.. Au Sud du Colorado (Argentine)
  • Fire history of a ponderosa pine/Douglas fir forest in the Colorado front range
  • Biogéographie ; Colorado ; Datation ; Etats-Unis ; Feu ; Forêt ; Montagne ; Sylviculture
  • Biogeography ; Colorado ; Dating ; Fire ; Forest ; Forestry ; Mountain ; United States
  • The main objectives of this study are : 1) to characterize the fire regime of an area of montane forest in the Colorado Front Range; and 2) to compare the utility of the different methods of dating fires in these forests.
  • Periglacial landforms of Southern Africa compared with those of Colorado and New Mexico
  • Afrique du Sud ; Colorado ; Domaine aride ; Etats-Unis ; Limite des arbres ; Montagne ; New Mexico ; Paléo-environnement ; Paléoclimat ; Périglaciaire
  • Arid land;Arid environment ; Colorado ; Mountain ; New Mexico ; Palaeo-environment ; Palaeoclimate ; Periglacial features ; South Africa ; Tree line ; United States
  • Periglacial landforms in southern Africa and the alpine zone of Colorado and New Mexico are compared. Lower altitudinal features in southern Africa reflect a drier environment. - (AJC)
  • The role of stratospheric intrusions in Colorado cyclogenesis

  • Atmosphere ; Atmospheric dynamics ; Colorado ; Cyclogenesis ; Cyclone ; Seasonal variation ; Stratosphere ; Troposphere ; United States of America
  • This paper attempts to clarify the extent to which intrusions of stratospheric air are associated with ordinary (non-explosive) cold-season Colorado cyclogenesis and compare the magnitude and motion of these intrusions (when present
  • Diversity and disturbance in a Colorado subalpine forest

  • Colorado ; Forest ; Mountain ; United States ; Vegetation ; Vegetation degradation ; Vegetation dynamics ; Wind
  • Diversity of understory plant species in a disturbed subalpine forest in the Colorado Rockies was examined to explore the hypothesis that intermediate levels of disturbance generate and maintain high levels of diversity. The AA. use a natural
  • experiment, where a severe but patchy windstorm damaged the canopy of a subalpine forest in the Colorado Front Range in 1974. The results suggest that intermediate levels of disturbance severity may offer more microhabitats, at least temporarily, for a wider
  • Tree-growth response to Enso events in the central Colorado Front Range
  • Circulation atmosphérique ; Colorado ; Dendrochronologie ; Dendrologie ; El Niño ; Etats-Unis ; Interaction océan-atmosphère ; Oscillation climatique ; Réchauffement climatique ; Température
  • Atmospheric circulation ; Climate oscillation ; Climatic warming ; Colorado ; Dendrochronology ; Dendrology ; El Niño ; Ocean atmosphere interaction ; Temperature ; United States
  • The inflence of climate associated with El Niño/Southern Oscillation (ENSO) events on tree growth in the central Colorado Front Range is investigated through the analysis of two high altitude tree-ring chronologies. Dendrochronological techniques
  • are used to determine if ENSO-related climatic effects are detectable in tree-ring width patterns in the central Colorado Front Range. The form of the tree growth response is identified and the variability of the influence of these events on tree growth
