Book Description
The Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns. Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

Book Description
South America is an area of fascination and study for geographers and other scholars from around the world, and its land and people have played important roles in the discovery and distribution of civilizations, resources, and nations for millennia. The region has long stimulated a large amount of research across the many subdisciplines of geography, and Thomas A. Rumney collects, organizes, and presents as many scholarly publications as possible in The Geography of South America: A Scholarly Guide and Bibliography. Every South American nation is included: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Surinam, Uruguay, and Venezuela. Beginning with an overview of the region as a whole, successive chapters, one per nation, are divided by specific subdisciplines of geography: cultural, social, economic, historical, physical and environmental, political, and urban. Each section is then divided by document type: atlases, books, book chapters, articles from scholarly journals, master’s theses, and doctoral dissertations. Although the majority of entries focus on English-language works, selected entries written in Spanish, French, German, and other languages are also included (with the entry titles translated into English and noted accordingly).

Book Description
Results of literature survey of knowledge on mountain glaciers in six regions of southern hemisphere: Andes of South America (Ecuador, Peru, Bolivia, Chile, Argentina), New Guinea, East Africa, Subantarctic Islands, New Zealand, and Antarctica. Includes discussions on distribution, extent, characteristics, and behavior of mountain glaciers as well as map and list of references for each regional discussion.

Book Description
This book is the last of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared. The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work group. Included with the publication is a CD with digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated. Where controversial interpretations are possible, such as for High Asia, they are indicated. All information on Quaternary glaciations worldwide is presented for the first time in a uniform format, including the mountain glaciations of regions such as Costa Rica, Ethiopia or Taiwan. The digital maps in this volume cover Latin America, Asia, Africa, Australasia, Antarctica. Both overview maps and more detailed maps at a scale 1: 1,000,000 are provided.

Book Description
This Atlas illustrates the significant reduction in glacier mass happening throughout the Andean region. It quantifies the contribution of glaciers to drinking water supplies in cities and to agriculture, hydropower and industries. A reduction in glacier mass results in a long-term reduction in seasonal melt water - which is the mainstay of livelihoods for millions of people.
