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 Issues in Ecology, Issue 05: Biotic Invasions

This report is an introduction to exotic species invasions. An exotic species becomes invasive, when it proliferates unchecked across the region in which it was introduced. The transformation from immigrant to invader and how humans act as dispersal agents is explained. Attributes of invaders, effects on native community, global ecological and economic consequences, prevention, and long term...

Activities engage students in data analysis and hypothesis testing, and will increase their understanding of the complexities of ecological phenomena. This Issue focuses on ecological consequences of introduced species using several case studies - zebra mussels, brown tree snakes,...

View Resource Pathways to Scientific Teaching, Chapter 5c of 7: Unleashing problem solvers: from assessment to designing research

Can transgenes be kept on a leash?” ask Marvier and Van Acker in the [attached] review article. “No”, they answer, “the movement of transgenes beyond their intended destination is a virtual certainty”, and furthermore “it is unlikely that transgenes can be retracted once they have escaped”. Would these bold statements engage students, revealing the realities and complexities of gene...

View Resource Pathways to Scientific Teaching, Chapter 7a of 7: Bridging the pathway from instruction to research

The Pathways articles to date were intended to engage faculty in teaching, learning, and assessment, especially in large enrollment courses. The challenge for many faculty who have changed their courses is to determine if the innovations actually improve student learning. This leads some faculty towards research models that require empirical evidence based on student assessment data. Here we...
