  1. Classification: patterns??

  2. Who lives in an ecosystem Vocabulary: Objective 1 – Biological community ecosystem organism community biological viablebiotic populationoffspring classify nucleus prokaryotic eukaryotic flora fauna vertebrates invertebrates deoxyribonucleic acid What is the objective for today?

  3. Ecosystems An ecosystem is a dynamic biological community of interacting organisms and their environment.

  4. Classification History • The current classification scheme is based on works by Swedish scientist Carolus Linnaeus (1758), American plant ecologist Robert Whittaker (1969), and by American microbiologist Carl Woese (1977). • Organisms were/are classified by: • Skeletons • Size, color, feathers, fur, etc… • Embryos • DNA • The International Commission on Zoological Nomenclature (ICZN) http://iczn.org/content/about-iczn

  5. Domain Prokaryotic - organisms is made of prokaryotic cells Kingdoms?? Eukaryotic – organisms is made of eukaryotic cells Kingdoms??

  6. Importance of classification in understanding the organisms: • relationship to others • evolution of the species • how the individuals within the population may interact with other populations

  7. Currently there are 1.3 million species of living organisms catalogued • 43,271 species of fungus • 1,367,555 species of animals • 321,212 species of plants • 30,000 formally named species of bacteria – too many to count probably more than a billion exist • Each year ~ 15,000 new species are discovered • Scientists estimate there are ~8.7 – 50 million species on Earth Zimmer, Carl. "How Many Species? A Study Says 8.7 Million, but It’s Tricky."NYTImes.com. The New York Times, 23 Aug. 2011. Web. 25 Aug. 2012. <http://www.nytimes.com/2011/08/30/science/30species.html>.

  8. Who lives in this community? Community - populations of organisms living in a the same area Population: a group oforganisms of thesame species that live in the same area and can produce viable offspring Biodiversity Tree size

  9. Practice – Grey Seal Domain: Kingdom: Phylum: Class: Order: Family: Genus & species:

  10. Practice – Grey Seal Domain – eukaryotic – meaning the organism is made of cells that house the DNA in a nucleus Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Pinnipedia Family: Phocidae Genus & species: Halichoerusgrypus
