2. Biotic Pollination Plant-animal interactions, often mutualisms Mystery slide…..

3. Outcrossing Favor outcrossing?

4. Outcrossing Favor outcrossing: 4) Self-incompatibility: stop

5. Pollination syndromes Disclaimer: We make broad generalizations and exceptions exist to most statements! Pollination Syndrome: flower & pollinator

6. Pollination syndromes Bee pollination Bees: –intelligent, agile –Good sight (incl. Leafcutter bee Bumble bee Halictid bee European honeybee

7. Pollination syndromes Flowers: –Colorful (not red) –Landing platform: –Mildly fragrant –Often nectar guides: Petals in visible light (top) and UV (bottom) Orchid flower with nectar guides (lines) on petals

8. Pollination syndromes Fremontodendron decumbens (endangered chaparral shrub) flowers UV reflectance photo (right) Tony Danza??

9. Pollination syndromes Beetle pollination Beetles: –Clumsy, dumb –Poor vision,

10. Pollination syndromes Bird pollination: Flower-visiting birds: –Agile, long beak –visual: see red –poor “smell”

11. Pollination syndromes Flowers: –red/orange –Nectar (m Aloe ???

12. Pollination syndromes Butterfly pollination Butterflies: good vision/smell, long tongue –Don’t hover well coiled tongue tongue extended

13. Pollination syndromes Flowers: –Color varies (blue, yellow, orange) Phlox pilosa

14. Pollination syndromes Bat pollination –Nocturnal: sight good (

15. Pollination syndromes Flowers –Open night: light color –Lots –May be pendant (). Parkia flowers

16. Pollination syndromes Bat pollination: Mainly tropical In U.S., saguaro Saguaro flowers Saguaro cactus

17. Pollination syndromes Moth pollination Moths: –Sight good (but

18. Pollination syndromes Flowers: –Open night –Sweet Night blooming jasmine

19. Pollination syndromes Moth story: nectar spur Nectar spur: long pouch (nectar @ bottom) Nectar spurs on columbine

20. Pollination syndromes Moth story: nectar spur Nectar spur: long pouch (nectar @ bottom) Selection for

21. Pollination syndromes Angraecum orchid (Madagascar) Nectar spur almost 1 ft. long!

22. Pollination syndromes Flesh fly pollination –Fly: Good smell Flowers Stapelia flower Asimina triloba

23. Fly flower: Rafflesia Ex, Rafflesia Root parasite Largest flower Some tourist guy…. Tony Danza? 2014

24. Pollination syndromes Largest inflorescence Corpse-flower (titan arum) Inside view spadix and spathe

25. Sexual Mimics Fls. look/smell like female bee/wasp –Study: Sexual mimic orchids Male “mating” with flower!

26. Pollination syndromes Grass pink orchid (Calopogon): –Fake stamens (on labellum) –No reward Calopogon orchid (fl. upside down!) Most orchids……

27. Biotic Pollination Mutualism: (+,+) interaction Do animal cheaters prosper?? Floral robbers! Cool robbers…

28. Biotic Pollination Floral Larceny: Visitor –Ex, snapdragon: (nectar robbing) Is robbing bad??

29. Biotic Pollination Neg. or pos.! Pos.: “legitimate”

30. Biotic Pollination Cheaters prosper?? Animal cheaters. Yucca moth story Yucca filamentosa

31. Biotic Pollination Pollination: yucca moth Behavior: female

32. Biotic Pollination Mutualism: plant pollinated, moth young eat seeds

33. Biotic Pollination Abort frs. w/ few seeds!

34. Biotic Pollination Interesting plant-animal interactions, often mutualisms Mystery slide….. Fish affect pollination?

35. Biotic Pollination Fish affect pollination? Peelbark St. John’s wort (Hypericum fasciculatum) Pond margins

36. Biotic Pollination Trophic cascade: Effects

37. Ch. 7: Plant Growth and Reproduction (Seed Dispersal)

38. “Thinking” like a plant…. Coast redwood –2,000 yrs.: to Safe site: location suitable

39. Why disperse? 1) Escape competition (parent/siblings) Seed shadow: pattern Bristlecone pine: lives up to 5000 years! Usually “acorn doesn’t fall far from tree”
