Book Description
This introduction to one of the most common phytoplankton types provides broad coverage from molecular and cellular biology all the way to its impact on the global carbon cycle and climate. Individual chapters focus on coccolithophore biology, ecology, evolutionary phylogeny and impact on current and past global changes. The book addresses fundamental questions about the interaction between the biota and the environment at various temporal and spatial scales.

Book Description
This volume provides a comprehensive overview of environmental aspects of the Sava River, which is the greatest tributary to the Danube River and the major drainage river system of South Eastern Europe. Hydroelectric power plants, river traffic, intensive agricultural activities, heavy industry and floods have considerable influence on the environment and biota in the basin. Summarizing the results that were gathered in the course of EU, bilateral and national projects, the book highlights the most important stressors and helps readers to better understand the impact of anthropogenic activities on the function of river basins. Topics include: transboundary water cooperation between the riparian countries; climate change projection, including its impact on flood hazards; evaluation of anthropogenic pollution sources; pollution of sediments, metal bioavailability and ecotoxicological and microbiological characterization of the river. The biological part also addresses quality aspects related to wildlife in river aquatic ecosystems (algae, macrophytes, zooplankton, macroinvertebrates and fish) and riparian ecosystems (amphibians, reptiles, birds and mammals). The general state of biodiversity and pressures caused by invasive aquatic species are also discussed.

Book Description
Floodplains are ecosystems which are driven by periodic inundation and oscillation between terrestrial and aquatic phases. An understanding of such pulsing systems is only possible by studying both phases and linking the results into an integrated overview. This book presents the results of a 15-year study of the structure and function of one of the largest tropical floodplains, the Amazon River floodplain. It covers qualitative aspects, e.g., adaptations of aquatic and terrestrial organisms to the flood pulse as well as quantitative aspects, e.g., studies of biomass, primary production, decomposition, and nutrient cycles. The authors interpret their findings and the most important data from other studies under an integrating scientific concept, the Flood Pulse Concept.

Book Description
Descended from a long and ancient lineage, tapirs are important tropical forest seed dispersers. However, today, all species of tapirs are threatened to various degrees by habitat destruction and hunting. This action plan was written with wildlife biologists, ecologists, administrators, educators and local conservation officials in mind and is aimed at those countries with tapir populations. It provides a brief natural history of each species and its objective is to aid in their conservation by catalyzing conservation action. In addition, it is hoped that the contents of the plan will stimulate further research into this fascinating group of animals.
