In this TIEE experiment, students investigate the costs of reproduction. In dioecious plants, a female's investment in reproduction is typically much greater than a male's, because while both sexes encounter the basic cost to produce a flower, only females have to allocate energy to seeds, exceeding the energy requirements to produce pollen. This 1-2 week field project tests whether the effects of...

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 students have little appreciation for how it is generated and little insight into how it should be critiqued. We propose a simple exercise that demonstrates the importance of a critical reading of not...

The road was widened from a single car road to a road that could easily handle two-way traffic and up to three cars in some areas. One can see a single lane in the right of the photo. One of the streams is down the mountain on the right side of...
