This January 2012 press release introduces and describes the significance of issue #15 of ESA's Issues in Ecology series, "Excess Nitrogen in the U.S. Environment: Trends, Risks, and Solutions."
It is not surprising that humans have profoundly altered the global nitrogen (N) cycle in an effort to feed 7 billion people, because nitrogen is an essential plant and animal nutrient. Food and...
The purpose of this report is to distill advances in the science of air pollution thresholds and to describe their use to assess, protect and manage the nation’s ecosystems and the vital services...
This November 2011 press release can be used as an accessible reading assignment to accompany and introduce a discussion of the ecological concepts included in issue #14 of ESA's Issues in Ecology...
All ecology texts include figures showing carbon cycles of various types (terrestrial, marine, global, etc). However, education research shows that introductory level students (both college and high...
This report discusses the three primary categories of atmospheric pollutants of aquatic ecosystems and how their ecological effects impact humans, fish and wildlife. Pollutants of concern such as...
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,...
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...
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...
In this Issue, students explore large-scale anthropogenic changes to the nitrogen cycle by examining studies that document anthropogenic inputs of nitrogen globally, the export of nitrogen from...
