Seed Dispersal in Tropical Forests

By HHMI BioInteractive

In this activity, students use data from published studies to understand patterns of seed dispersal and apply these ideas to the design of a conservation area.

Description

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.
