This short film includes interviews with water researchers and presents basic concepts of hydrologic cycle. Understanding where water goes is important for understanding the environmental effects of many of our activities, from land development to fertilizer use or how will harvesting trees change the likelihood of flooding or landslides.
This report presents an overview of how humans have altered the global nitrogen cycle. An introduction to the nitrogen cycle is provided; as well as human induced nitrogen fixation and its impact on the atmosphere, carbon cycle, aquatic and terrestrial ecosystem function, and biodiversity. The importance of nitrogen as a primary building block of life and its role in biological processes is also...
This article discusses the importance of teaching current environmental issues through laboratory exercises. It describes the methods that would be used in a lab exercise involving tree measurement to explain biogeochemical cycling of carbon in the atmosphere.
This report addresses pollution of aquatic ecosystems that originate from multiple unidentified sources or non point sources. Non point sources of phosphorus and nitrogen are of concern as they cause eutrophication or excessive enrichment of surface waters. Effects and remediation strategies are discussed. Non point sources, such as agricultural, urban and atmospheric ones are discussed. ...
This report addresses coastal ecosystem degradation as a consequence of human driven increases in nutrients such as Nitrogen and Phosphorus. Effects on ecological communities such as algal blooms, loss of seagrass beds, and coral leaching are described. Excess nitrogen is emphasized as being the limiting nutrient in coastal systems. Political and scientific consideration to support the control...
