1.Introduction -- Section I: Temperate forest-grassland ecotones: prairies, steppes, and pampas -- 2. Woodland-grassland ecotonal shifts in environmental mosaics: lessons learnt from the environmental history of the Carpathian Basin (Central Europe) during the Holocene and the last ice age based on investigation of paleobotanical and mollusk remains -- 3. Ecotones as complex arenas of disturbance, climate and human impacts: the trans-Andean forest-steppe ecotone of northern Patagonia -- 4. Woody-Herbaceous-Livestock Species Interaction -- 5. Woody plant invasions in Pampa grasslands ? a biogeographical and community assembly perspective -- Section II: Tropical forest-grassland ecotones: old fields, savannas, and llanos -- 6. Post-agricultural ecotones in Puerto Rico -- 7. South Brazilian forest-grassland ecotones: Dynamics affected by climate, disturbance and woody species traits -- 8.Long-term perspectives on Tropical forest-savanna dynamics in lowland Bolivia from the last ice age until the present -- 9.Usi
Ecotones are dynamic over-lapping boundary areas where major terrestrial biomes meet. As past studies have shown, and as the chapters in this book will illustrate, their structure, size, and scope have changed considerably over the millennia, expanding and shrinking as climate and/or other driving conditions have also changed. Today, however, many of them are changing at a rate not seen for a long time, perhaps largely due to climate change and other humaninduced factors. Indeed, ecotones are more sensitive to climate change than the biomes on either side, and thus may serve as critical early indicators of future climate change. As ecotones change, they also redefine the limits of the biomes on either side by altering their distributions of species because, in addition to their own endemic species, any ecotone will also have species from both adjoining biomes. Consequently, they may also be places of high levels of species interaction, serving as active evolutionary laboratories, which generate new species th
