Activity Description of "Cricket Patch Density"

Title Cricket Patch Density
Audience Biology- 10-14
Abstract A semester-length field study investigating the size of a grassland patch as related to cricket population density. By utilizing the mark-recapture method, students apply the Lincoln-Peterson equation to population estimates. Comparisons are made between large grassy patches and small ones for population density. Findings can then be related to further research on habitat fragmentation and species diversity.
