Archaeological perspectives on prehistoric conservation in western North America
The archaeological record represents a potentially critical source of information on past relationships between human hunters and populations of game animals. Archaeological research in the last 40–50 years has produced two alternative views on these relationships: one that Native people were knowledgeable, benevolent conservators of game and an alternative that suggests that they depleted and ...
متن کاملDeclining Mountain Snowpack in Western North America*
JANUARY 2005 AMERICAN METEOROLOGICAL SOCIETY | ountain snowpack in western North America is a key component of the hydrologic cycle, storing water from the winter (when most precipitation falls) and releasing it in spring and early summer, when economic, environmental, and recreational demands for water throughout the West are frequently greatest. In most river basins of the West, especially in...

It concludes with some reflective comments on the author’s Archaeological Theory: An Introduction, in advance of the third revised edition.
متن کاملRecent growth of conifer species of western North America: assessing spatial patterns of radial growth trends
We explored spatial patterns of low-frequency variability in radial tree growth among western North American conifer species and identified predictors of the variability in these patterns. Using 185 sites from the International Tree-Ring Data Bank, each of which contained 10–60 raw ring-width series, we rebuilt two chronologies for each site, using two conservative methods designed to retain an...
متن کاملVariability and trends in Mountain Snowpack in Western North America
Snow course and SNOTEL measurements of spring snowpack, corroborated by a physically-based hydrologic model, are examined here for climate-driven fluctuations and trends during the period 1916-2002. Much of the mountain West has experienced declines in spring snowpack, especially since mid-century, and despite increases in winter precipitation in many places. Analysis and modeling shows that cl...
