Vine infestation on Cecropia trees
Description
Presence/absence data of vines on Cecropia trees of two morphotypes.
Usage
embauba
Format
A data frame with 152 rows (plants) and 2 variables:
- morphotype
the tree morphotype, factor with two levels
- with.vines
does the tree harbor vines? Logical.
Details
Two morphotypes of Cecropia trees differ in the occupancy by ant colonies. Ants attack and drive out other insects that get to the trees. To test if this protection also affects infestation by vines, trees of similar size of both morphs were sampled and inspected for the presence of vines.
