https://doi.org/10.1007/978-1-349-20346-8This chapter documents seed traits and seed production near treeline, germination and seedling establishment, and the progession of growth and development to the sapling stage. Population processes and demography data are presented from around the world. Life cycle issues and reproductive limitations are discussed.

Developments in West German PoliticsAfter offering a conceptual framework for stress in an evolutionary context, this chapter summarized the evidence and the mechanisms of freezing tolerance in treeline trees from all climatic zones. A number of other factors that may impose stress at a regional scale (high latitudes, winter phenomena) are discussed.

Treeline patterns,This chapter describes the treeline phenomenon with a global perspective. It summarizes tree taxa found at treelines worldwide, reasons for regional depressions or advances of treeline position, the global and latitudinal spectrum of treeline elevations, and how scales of space and time matter for treeline structure.

Growth and development,This chapter offers an in-depth debate and data on how trees grow near their elevational limit, how cambial and apical growth is controlled, and how growth in shoots and roots responds to temperature. A special section addresses elevational trends in tree phenology (leafing, flowering).
