  1. Monday, Jan 12 Outline of Topics • Powers of Ten; Review scale – How small/big size? How short/long time? • Why/how biologists classify things • Brief survey of kingdoms • Prokaryotes & Viruses

  2. evolution community succession organismal interactions molecules cells organisms ecosystems cellular interactions Intersection of Time and Space molecular interactions

  4. Terminology • Terminology is not the focus of this course • You need to learn some basic terms: those in lab exercises and lecture notes • “Taxa”: remember the phyla, (classes), and representative genera I introduce in lecture • Do not remember all the bold-faced terms in the text • (although it might be nice for you to know them when you read the text – See Starr & Taggart Glossary) • Watch the references to chemistry and cells • (review chapters on chemistry and cells)

  5. New species must be validly described

  6. How many species are there? Thousands of described species per phylum Data from World Resources Institute Total = 1,381 thousand

  7. How does this relate to the biodiversity we see today?

  8. The six “kingdoms” Bacteria Archaea Protista Plants Fungi Animals Simple diagnostic characters won’t always classify every organism into its proper kingdom Prokaryotic / eukaryotic Cell arrangement Metabolism of carbon (autotrophs or heterotrophs?) The number of kingdoms is debatable Six Kingdoms defined – in Domain Bacteria – in Domain Archaea } in Domain Eukarya
