A collection of slides about the effects of frost on Colorado wildflowers at the Rocky Mountain Biological Laboratory (RMBL). RMBL is a high-altitude field research station at 9,500 feet in the Colorado Rocky Mountains. RMBL has supported field work since it was founded in 1928, and is the location of the research described in this slide show.

During two lab periods, students collect demographic data on perennial plants and then use these data in a matrix model to perform population viability analyses. During the first lab, students tag and record data on individual plants in the field. During the second lab, students compile these data to build transition matrices and then use R to run simulations. In the first year that instructors...

In this study, students investigate whether and how much the native understory shrub pawpaw (Asimina triloba) may affect tree regeneration in a forested habitat. During one lab period in the field, they collect data on the densities of tree seedlings and saplings under varying densities of pawpaws. During a second lab period in a classroom, they test whether tree densities are lower under...

One of the simplest questions an ecologist can ask about a site is how many species live there. The answer is important for basic researchers and managers alike, but can be deceptively hard to obtain. This exercise introduces students to the issues surrounding the estimation of species richness, and can be completed in a single three-hour lab session. Students will learn to collect data in the...
