Big mushrooms

Earliest fungal-like fossils (septate networks) date to 1.4 bya, lived in benthic marine habitats. Fungi remain important decomposers in marine and freshwater ecosystems

Colonized land in Cambrian, before plants; maybe as lichenous symbiotes. Prototaxites of the Silurian was 8m tall and 1m wide!

  • IV. The Domain Eukarya

  • E. Fungi

  • Overview:

  • “Body Plan”

  • Ecological Roles

  • - symbionts

Lichens: fungus + algae or cyanobacteria

http://www.elkhornslough.org/sloughlife/plants/lichen.htm

Arbuscular mycorrhizae – found in 80% of vascular plant families; in oldest vascular plant fossils (Rhynie Chert – 420 mya)

  • IV. The Domain Eukarya

  • E. Fungi

  • Overview:

  • “Body Plan”

  • Ecological Roles

  • - symbionts

  • Increase absorptive surface area of root system

  • Secreted enzymes increase absorption of N and P in particular

  • Can connect to plants of different plant species, and even transfer nutrients between them

  • One species may attract and poison insects (springtails), and digest and absorb their nitrogen (up to 25% of a plants nitrogen budget!)

  • Present in oldest vascular plant fossils, and molecular analyses confirm an ancient association which may have been critical for plants to colonize land

  • - Chytridomycota

40% of amphibian populations are in decline worldwide, probably due to a combination of climate change, pollution, habitat loss and degradation, and chytrid fugal infections.
