Sources of reactive nitrogen affecting ecosystems in Latin America and the Caribbean: current trends and future perspectives.- A review of anthropogenic sources of nitrogen and their effects on Canadian aquatic ecosystems.- More is less: agricultural impacts on the N cycle in Argentina.- Human activities changing the nitrogen cycle in Brazil.- Assessment of nitrogen flows into the Cuban landscape.- Urban influences on the nitrogen cycle in Puerto Rico.- Nitrogen and phosphorus budgets for a tropical watershed impacted by agricultural land use: Guayas, Ecuador.- The influence of climate on average nitrogen export from large watersheds in the Northeastern United States.- Coastal eutrophication assessment in the United States.- Nitrogen cycling in tropical and temperate savannas.- Nutrient-chlorophyll relationships in tropical-subtropical lakes: do temperate models fit?.- The stable carbon and nitrogen isotopic composition of vegetation in tropical forests of the Amazon Basin, Brazil.
Advances in our understanding of the nitrogen cycle and the impact of anthropogenic activities on regional to global scales depend on the expansion of scientific studies to these fast-developing regions. This book presents a series of studies from across the Americas whose aim is to highlight key natural processes that control nitrogen cycling as well as discuss the main anthropogenic influences on the nitrogen cycle in both the tropical and temperate regions of the Americas.
