Students will develop a mathematical model of the relationship between atmospheric CO2 and the number of stomata on a leaf (Stomata Index). They will evaluate the model graphically, statistically, and biologically, and then use it to estimate CO2 levels in the distant past.

Using the Hardy-Weinberg Equations: Quantifying Natural Selection and Allele Frequencies

11 May 2023 | Contributor(s): Gina Wesley, Sean McNamara, Kelly Livernoche, Kiersten Newtoff, William Gretes, Allison Bell, Jeff Leips | doi:10.25334/R6PF-P563

This module contains exercises designed to walk students through a real-world example of the coevolution of fruit color and primate frugivore color vision. Students will apply the Hardy-Weinberg Principle to quantitatively determine if evolution is occurring. This will be accomplished through...

The Edge Effect

03 May 2023 | Contributor(s): Sean McNamara, Kiersten Newtoff, Kelly Livernoche, Allison Bell, Jeff Leips, Gina Wesley, William Gretes | doi:10.25334/JQ94-R333

This module has students venturing outdoors to take a 50m transect and collect abundance data on plants utilizing quadrats in both edge and interior environment. Mathematically the goals of this module are to emphasize how sample size can influence data analysis and variance within the data set....
