View Resource Changes in Lake Ice: Ecosystem Response to Global Change

This TIEE Data Set presents long term data on changes in dates of ice cover in three Wisconsin lakes. Global temperatures have increased by about 1 degree Fahrenheit during the last century, most likely the result of “greenhouse gases” such as carbon dioxide from burning of gasoline, oil, and coal. There are many environmental consequences of warmer temperatures, some unexpected. One challenge ...

View Resource Long-term Response of an Arctic River Community to Phosphorus Fertilization

With this TIEE Data Set, students assess effects of phosphorus addition on algae, moss, mayflies, and arctic grayling fish in the Kuparuk River, in the foothills of the North Slope of Alaska. Data were taken over 15 years at the Arctic Long Term Ecological Research (ARC LTER) site at the Toolik field station. Phosphorus was added to the river as an experiment to study the effects of nutrient...

View Resource What Are the Ecological Impacts of Plant Biotechnology?

Biotechnology is viewed by many scientists and the public as a solution to a potential food supply crisis in the coming decades; however, debates about the use, ethics, and the effectiveness of genetically engineered crops are now growing in intensity. This Figure Set guides students through the interpretation of some of the data collected so far to inform discussion about genetically engineered...

View Resource Vulnerability of High Diversity Habitats to Introduced Species

This Issue focuses on a research article by Stohlgren et al. (2003) and two responses to it that were published in Frontiers in Ecology and the Environment. The article discusses the ecology of invasive species and the vulnerability of high diversity communities to invasives. Students, like many others, might assume that habitats with low plant diversity are more vulnerable to invasions of...

View Resource Evolution of Ideas about Causes of Amphibian Deformities

This Issue focuses on a research article by Blaustein and Johnson (2003) that was published in Frontiers in Ecology and the Environment. The article discusses amphibian deformities, which may be related to a global decline in amphibians. By working with this paper and additional figures, students come to appreciate the complexity of biodiversity loss. Specifically, they gain an understanding of...
