First multi-year cumulation covers six years: 1965-70.
This volume is the fourth in the series of the Proceedings of the College Park Colloquia on Chemical Evolution. These Colloquia, and the resulting Proceedings, are presented in the interest of fostering the impact of the interdisciplinary nature of chemical evolu tion on contemporary scientific thought. vii EDITORS'INTRODUCTION The Fourth College Park Colloquium on Chemical Evolution was held on October 18 - 20, 1978 at the University of Maryland. The meeting, supported by the National Aero nautics and Space Administration and the National Science Foundation, centered on the variable environments, both past and present, in which living organisms have survived, grown, and evolved - the limits...
A discussion of the direct and indirect mechanisms by which fire and climate interact to influence carbon cycling in North American boreal forests. The first section summarizes the information needed to understand and manage fires' effects on the ecology of boreal forests and its influence on global climate change issues. Following chapters discuss in detail the role of fire in the ecology of boreal forests, present data sets on fire and the distribution of carbon, and treat the use of satellite imagery in monitoring these regions as well as approaches to modeling the relevant processes.
Maps, as we know, help us find our way around. But they're also powerful tools for someone hoping to find you. Widely available in electronic and paper formats, maps offer revealing insights into our movements and activities, even our likes and dislikes. In Spying with Maps, the "mapmatician" Mark Monmonier looks at the increased use of geographic data, satellite imagery, and location tracking across a wide range of fields such as military intelligence, law enforcement, market research, and traffic engineering. Could these diverse forms of geographic monitoring, he asks, lead to grave consequences for society? To assess this very real threat, he explains how geospatial technology works, what...
Global climate change is a certainty. The Earth's climate has never remained static for long and the prospect for human-accelerated climate change in the near future appears likely. Freshwater systems are intimately connected to climate in several ways: they may influence global atmospheric processes affecting climate; they may be sensitive early indicators of climate change because they integrate the atmospheric and terrestrial events occurring in their catchments; and, of course, they will be affected by climate change. An improved predictive understanding of environmental effects on pattern and process in freshwater ecosystems will be invaluable as a baseline upon which to build sound pro...
