1. Global Climate Change Earlier springs in temperate zone –Asynchrony: Species may not respond in same way –Ex, flycatchers migrate Africa to Holland to nest –Lesson??

2. Global Climate Change Earlier springs in temperate zone –Food lack during hatching

3. Pollination Def’n: transfer pollen from stamen to stigma

4. Fertilization Fertilization: union sperm with egg to form zygote

5. Alabama Leather Flower Endangered species (Federal list) Fruits: one flower can make up to 10 single-seeded fruits

6. Alabama Leather Flower Endangered species –6 populations

7. Alabama Leather Flower Two main pollinator insects –Bumblebee in early flowering years –Solitary bee in late flowering years BumblebeeSolitary bee

8. Alabama Leather Flower Pollinator in early blooming year: Bumblebee –On average: 1 visit to a flower makes 3 fruits –Slow: visits only 1/3 as many flowers as a solitary bee in same time

9. Alabama Leather Flower Pollinator in late blooming year: Solitary bee –On average: 1 visit to a flower makes 3 fruits –Fast: can pollinate 3 times as many flowers as a bumblebee!

10. Alabama Leather Flower Question: what may happen to seed production if early bloom years become more frequent? Pollination game!
