1 | <p>In this exercise, students investigate differences in seed dispersal between two tropical tree species, one wind-dispersed and one bird-dispersed. Student make predictions about the seed shadow of the two species and then compare their predictions to seed dispersal patterns revealed in graphs. Students also explore the relationship between seed survival as a function of distance from the maternal tree. Students apply what they learn to the design of a conservation area. In an optional activity, students examine the degree to which results from the study support the Janzen-Connell hypothesis.</p> | 1 | <p>In this exercise, students investigate differences in seed dispersal between two tropical tree species, one wind-dispersed and one bird-dispersed.

3 | <p>Added modification of some botany background for an ecology class and the application of this topic to the ecology of different environments. Comparison of causes of fragmentation in the tropical environment in the activity to an urban environment. Discussion about competition between plant and how the type of seed transport affects distances of transport and germination rates.</p> |
