Vegetation history
The analysis of vegetation history is one of the prime objectives for vegetation scientists. In order to understand the recent composition of local floras and plant communities a second knowledge of species com position during recent millenia is essential. With the present concern over climate changes, due to human activities, an understanding of past vegeta tion distribution becomes even more important, since the correlation between climate and vegetation can often be used to predict possible impacts to crops and forests. I was very fortunate to receive the help of Drs. Webb and Huntley to compile this volume on vegetation history. They have collated an impres sive set of papers which toget...
Henry Paul Hansen Papers
The Henry P. Hansen Papers include publications of Hansen and his colleagues from the United States and Norway; correspondence files; research files containing field notes, manuscripts, and a set of pollen sample slides; information on pollen analysis methods and pollen classifications; two NSF research proposals, one regarding Peat Bogs in Eastern Norway and another on the Three Sisters Wilderness Area; photos of Hansen and of wilderness landscapes; teaching materials including handouts for palynology courses; 1906 map of Washington floral regions, plus a 1941 map of Oregon, Washington and some of the Canadian provinces; papers and information files on palynology and geology; copies of masters thesis of Hansen's son, David Henry Hansen.
Paleoclimatology and Paleometeorology: Modern and Past Patterns of Global Atmospheric Transport
The NATO Advanced Research Workshop on "Paleoclimatology and Paleometeorology: Modem and Past Patterns of Global Atmospheric Transport" (held at Oracle, Arizona, USA from November 17-19, 1987) brought together atmospheric chemists, physicists, and meteorologists who study the origin and transport of modem-day mineral and biological aerosols with geologists and paleobotanists who study the sedimentary record of eolian and hydrologic processes along with modelers who study and conceptualize the processes influencing atmospheric transport at present and in the past. Presentations at the workshop provided a guide to our present knowledge of the entire spectrum of processes and phenomena importan...
The Oxford Handbook of the Prehistoric Arctic
Despite its extreme climate, the North American Arctic holds a complex archaeological record of global significance. In this volume, leading researchers provide comprehensive coverage of the region's cultural history, addressing issues as diverse as climate change impacts on human societies, European colonial expansion, and hunter-gatherer adaptations and social organization.
