Presentation Transcript

  1. Bio 161 Community Ecology: Symbiosis.

  2. Adaptation to the Environment

  3. Adaptation to the Non-living or Abiotic environment. Desert plants

  4. Adaptation to the non-living or abiotic environment. Rain forest

  5. Adaptation to the non-living or abiotic environment. Canyon tree frog (camouflage – cryptic coloration)

  6. Bio 161 Organisms are adapted to the living or biotic environment: Symbiosis.

  7. Symbiosis: interactions between species

  8. Symbiosis: interactions between species

  9. Symbiosis Neutralism Commensalism Mutualism Competition Antagonism

  10. Symbiosis: Neutralism

  11. Colorado grasslands and …

  12. Golden eagle?

  13. Jackrabbit

  14. Symbiosis: Neutralism.

  15. Symbiosis: commensalism

  16. Symbiosis: amensalism

  17. Cattle and sheep make trails in grass that they trample and without realizing it are killing the grass.

  18. Symbiosis: Amensalism or antagonism?

  19. Soil bacteria secrete antibiotics.

  20. Creosote bushes (Mojave desert) secrete growth inhibitor in the soil.

  21. Black walnut tree secrete JUGLONE that prevents and kills many other plants.

  22. Symbiosis: Amensalism or antagonism?

  23. Symbiosis: mutualism.

  24. Symbiosis: mutualism. Many examples:

  25. Symbiosis: mutualism Pollination:

  26. BeesHoney bee

  27. Hawkmoth approaching orchid flowers at the beginning of a foraging event.

  29. Orchid pollinia attached to dorsal base of the hawkmoth tongue.

  30. Orchid with spiral spur probed by hawkmoth

  31. Orchid pollinia at the ventral base of the hawkmoth proboscis.

  32. Symbiosis: mutualism Natural Theology:

  33. Comparison of orchid nectar spur and hawkmoth proboscis or tongue.

  34. Why is the spur of the orchid as long as the proboscis of the moth?

  35. Star orchid Angraecumsesquipedale) and hawk moth (Xanthopanmorganiipraedicta). For the orchid to develop the very long spur (12 inches) and the moth to develop a correspon-dingly long proboscis the interests of the two mutualists must be different.

  36. Orchid flower resembling female wasp (or fly)

  37. END
