  • Latitudinal range variation of trees in the United States : a reanalysis of the applicability of Rapoport's rule
  • Biogeography ; Conifer ; Latitude ; Leafy ; Southern United States ; Spatial distribution ; Taxonomy ; Theory ; Tree ; United States of America ; Vegetation
  • with Rapoport's rule in the United states are not restricted to high latitudes and are not the result of a boundedness effect but may be intimately linked with the glacial history and physical geography of North America.
  • Fluvial response to land-use change in the Southern Appalachian region : a century of investigation
  • Agricultural land use ; Appalachian Mountains ; Deforestation ; Fluvial dynamics ; Impact ; Land use ; Stand treatment ; Stream ; Twentieth Century ; United States of America
  • This paper explores the history of land-use change and the study of fluvial response to such changes in the Southern Appalachian region over the past century. It examines Southern Appalachian investigations of fluvial response to land-use change
  • in the broader contexts of U.S. national trends, and considers opportunities for further research in the Southern Appalachian region.

  • Habitat islands : feral parrots in southern California
  • Biogeography ; California ; Habitat;Settlement ; United States ; Vegetation ; Zoogeography
  • At least eight species of parrots, most of them native to South America, have naturalized in southern California suburbs where they feed mainly on fruits and seeds from introduced ornemental plants. Their colonization potential is still unclear
  • Relict soils of subtropical regions of the United States
  • Arid lands ; Cenozoic ; Paleosols ; Pedogenesis ; Soil ; Soil property ; Subtropical zone ; United States
  • Five soils from California, Arizona, Nevada, Texas, and North Carolina illustrate some of the kinds of relict soils in the southern United States. Desert pavements, plinthite, duripans, petrocalcic horizons, and argillic horizons are examples
  • Impact of the southern oscillation on the North American Southwest Monsoon
  • Arizona ; Atmospheric circulation ; Climatic anomaly ; Climatic variation ; Monsoon ; New Mexico ; Numerical model ; Precipitation ; Teleconnection ; United States
  • The objective of this study is to examine the relationship between fluctuations in the Southern Oscillation and the pattern and intensity of precipitation anomalies associated with the Southwest Monsoon. Sixty-five years (1920-1984) of July
  • and August monthly precipitation data from Arizona and New Mexico are normalized using a square root transformation, converted into z-scores, and stratified according to onset and following years for Warm Events and Cold Events of the Southern Oscillation.
  • Drift volume in the southern peninsula of Michigan. A prodigious Pleistocene endowment
  • Glacial erosion ; Glacial features ; Glaciation ; Kame ; Michigan ; Moraine ; Pleistocene ; Quaternary ; United States
  • Michigan's Southern Peninsula is by far the largest drift repository in the Great Lakes Area. The distribution, however, is very uneven, as is the underlying bedrock surface. These variations and known surface characteristics provide a basis
  • for the first qualitative and quantitative identification of distinct drift realms. Comparative analysis within the peninsula shows that Pleistocene glaciation completely transformed the topography to the north, whereas the southern half has palimpsest
  • Welcoming the wind ? Determinants of wind power development among U.S. States
  • Electricity ; Energy ; Farm ; United States of America ; Wind energy
  • The article analyses the emerging geography of wind energy on a state-by-state basis. The primary determinants of wind energy development among U.S. states are human geographic factors of population distribution, and resulting geography
  • of electricity demand and transmission line accessibility, together with state-based energy policies, including electric utility restructuring, renewable postfolio standards, and procedures for siting and permitting wind farms.

  • Industrialization and racial inequality within the American South, 1950-1970 in Metropolitan and regional change in the United States.
  • Causal models are employed to demonstrate how separate threads of southern modernization, such as agricultural consolidation and the expansion of manufacturing, influenced the geography of racial inequality. The differential effects observed suggest

  • The fate of eroded soil: sediment sinks and sediment budgets of agrarian landscapes in southern Minnesota, 1851-1988
  • Flood ; Floodplain ; Minnesota ; Palaeosol ; Sediment budget ; Sediment transport ; Soil erosion ; United States ; Watershed
  • This paper examines the fate of eroded soil by tracing the distribution of eroded sediment and constructing the sediment budgets of three medium-size drainage basins in southern Minnesota. This research attempts to improve our understanding
  • Fan and playa areas in southern California and adjacent parts of Nevada
  • Alluvium ; Arid land;Arid environment ; California ; Closed depression ; Desert ; Nevada ; Sediment budget ; Tectonics ; United States
  • In bolsons in the desert regions of southern California and adjacent parts of Nevada, the area underlain by alluvial fan gravels and playa sediments is generally ∼ 1-2 times the area being eroded to produce those sediments. In certain larger basins
