Ecological Roles of Amphibians and Fungi: Interactions in the Natural World

Explore the unique ecological roles of amphibians and fungi in different environments. Learn about amphibians as keystone species and their similarities to humans, including external fertilization and permeable skin. Delve into the disease dynamics of smallpox, parasites, and zoonoses like jock itch. Discover the web of interactions in ecosystems and the structural complexities of these organisms. Uncover the fascinating world of chytrids as fungi and their functions as saprophytes and parasites. Gain insights into the challenges organisms face on land, such as desiccation and ultraviolet radiation, and the advantages of terrestrial life.

  1. BIO 110, Life Science Summer 2012

  2. Readings • Textbook • pp. 328-332, Fungi • p. 357, Amphibians • p. 525, smallpox • http://en.wikipedia.org/wiki/Zoonosis (in case you’re interested)

  3. Ecological role of amphibians • Not well known in many environments • Keystone species?

  4. Why are amphibians different? • How are they the same (as us)? • Aquatic immature forms • External fertilization • Permeable skin

  5. Why is the disease different? • What are parasites? • Eaten alive • Infection • Host specificity • Smallpox and AIDS • Staph and strep • Zoonoses • Jock itch

  6. Web of interaction • No organism exists alone • Structural complexity

  7. Chytrids as fungi • Mushrooms, molds, and yeasts • Saprophytes and parasites • Why does Penicillium kill bacteria? • Flagella • Origin • Function • Lost and gone forever

  8. Land and water • Water, chemistry and life • Challenges of land • Desiccation • Motility (organisms and gametes) • Ultraviolet radiation • Advantages of land
