View Resource Effects of frost on wildflowers: an unexpected consequence of climate change [resource group]

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.

One of the streams is down the mountain on the right side of...

One of the berries has been nibbled by a herbivore, most likely a insect. You can see from the nibbled surface how the wax forms a layer across the surface. Clearly the berry was distasteful to the (presumed) insect that was eating it as...

View Resource An in-class role-playing activity to foster discussion and deeper understanding of biodiversity and ecological webs

In a general sense, biodiversity is an intuitively simple concept, referring to the variety of Earth’s organisms. Ecologists, however, conceptualize biodiversity in a more nuanced, multidimensional way to reflect the enormous diversity of species, niches, and interspecific interactions that generate spatiotemporal complexity in communities. Students may not fully comprehend o...
