Abstract: Objectives We are studying different cottonwood hybrid zones throughout the Rocky Mountains. Different hybrid zones with different plant genetic structures should support different species of animals, especially insect herbivores. In Grand Teton National Park, there are hybrid zones between black cottonwood (Populus trichocarpa) and narrowleaf cottonwood (Populus angustifolia). Our first objective is to collect leaves and, using molecular genetic techniques, characterize the genetic structure of the hybrid zone. In subsequent years, we will conduct insect surveys on these hybrid trees. These results will be compared to those in other cottonwood hybrid zones. Findings and Status In 1998 we collected leaves from 50 cottonwoods in the Cottonwood Creek drainage. Genetic analyses of these trees are approximately half completed and will be finished this summer. This year, we will collect additional leaves for morphological analyses and begin insect surveys.

We are studying different cottonwood hybrid zones throughout the Rocky Mountains. Different hybrid zones with different plant genetic structures should support different species of animals, especially insect herbivores. In Grand Teton National Park, there are hybrid zones between black cottonwood (Populus trichocarpa) and narrowleaf cottonwood (Populus angustifolia). Our first objective is to collect leaves and, using molecular genetic techniques, characterize the genetic structure of the hybrid zone. In subsequent years, we will conduct insect surveys on these hybrid trees. These results will be compared to those in other cottonwood hybrid zones.
Findings and Status
In 1998 we collected leaves from 50 cottonwoods in the Cottonwood Creek drainage. Genetic analyses of these trees are approximately half completed and will be finished this summer. This year, we will collect additional leaves for morphological analyses and begin insect surveys. |
