View Resource The influence of Acidification on Ammonification

This experiment examines the influence of moderate (pH 5.5) to extreme (pH 3.5) sulfuric acid-induced acidification on the ability of soil microorganisms to conduct ammonification. Two common soil...

View Resource The Kuparuk River, an arctic stream ecosystem on the North Slope of Alaska.

The Kuparuk River flows to the Arctic Ocean from the foothills of the Brooks Range, seen to the south in the background. The Kuparuk River was experimentally enriched with phosphorus every summer...

View Resource The Use of Fairy Tales and Beer Bets as Ways to Help Students in Ecology and Environmental Science Courses Develop Imagination and Confidence

This article relays a 'fairy tale' version of biogeochemical cycling to emphasize the importance of imagination in the learning setting. It also describes an on going classroom activity where 'beer...

View Resource Tree Measurement and Carbon Cycling: A Laboratory Exercise

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...

View Resource Urban to Rural Gradients – Exploring Trends in Organismal, Community and Ecosystem Ecology

Urban ecology is quickly becoming a major subdiscipline in ecology and being included in the syllabi of most college-level ecology courses. This field and laboratory exercise is designed to be...

View Resource Using on-line data sources to allow students to test hypotheses about river flow and effects on remotely sensed coastal ocean properties.

River discharge couples terrestrial ecosystems with oceanic ecosystems. Fluctuations in river discharges from drought or flood events can have significant effects on coastal ecosystems.

View Resource Using Stream Leaf Packs to Explore Community Assembly

In this TIEE experiment, students will explore functional and taxonomic diversity in a stream ecosystem, learn about food web relationships, and learn about the ways in which abiotic and biotic...

View Resource What NOT to Read: A Lesson in Reviewing and Critiquing Scientific Literature Using a Junk Science Article on Climate Change

A central challenge for college-level science and ecology students is understanding the significance of peer-reviewed scientific literature. Such literature is increasingly easy to access, but...
