Rubber Tree (taxon) |
Hevea braziliensis |
|
Name 7 types of pharmacologically active compounds used by trees. |

Tree defense: Replaces arginine, an amino acid, in insects |
|
Three effects of tree defenses that are insect hormones |
insects remain in larval stage and fail to reproduce, skip vital larval stages and become adults too early and die before reproducing, substances that interfere with molting process |
|

|
For every structural or chemical defense system in a plant, there is greater than 1 species of herbivore that has coevolved to challenge it |
if a herbivore consumes the same, low toxicity part on many types of plants, it may have some resistance to many compounds; if a herbivore feeds on all parts of only one plant species, it may have high resistance to just one or only a few compounds |
|

Few resources mean greater protection mechanisms, harder to replace tissue means necessary to prevent herbivory |
