  3. IV. The Domain Eukarya • E. Fungi • Overview: • “Body Plan” http://www.rhizomes.net/issue15/groves/index.html mycelium http://www.ipm.iastate.edu/ipm/hortnews/node/98

  4. IV. The Domain Eukarya • E. Fungi • Overview: • “Body Plan” 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! http://scienceblogs.com/zooillogix/2007/04/giant_prehistoric_organism_ide.php

  7. 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) http://sarcozona.org/2009/03/18/what-do-you-know/

  8. 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 http://directory.leadmaverick.com/Denton-Pest-Control-Service/DallasFort-WorthArlington/TX/10/10739/index.aspx http://www.ces.ncsu.edu/depts/ent/notes/Urban/springtails.htm

Fungi • Overview: • “Body Plan” • Ecological Roles • Generalized Life Cycle • Fungal Diversity • - 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. http://cisr.ucr.edu/chytrid_fungus.html
