Welcome to Biol 120 Local Flora!
2
Syllabus info: Instructor: Dr. Vic Landrum Research area: Succulent plant evolution, systematics, and anatomy. Office Hrs.: before, after class Email: jlandrum@olympic.edu Textbooks: Wildflowers of the Pacific Northwest, about $19 Trees and Shrubs of Washington State, about $13 Systematic Botany (free textbook!)

The course basics: This course is mostly a field course, with some lab work/preparation of plant specimens for your collections. The principles and methods you'll learn in this course apply to any biological group, not just plants. I always hope that a field course like this will spark a lasting curiosity about our natural world in you. Enter this course with an open mind and you'll do well.
4
Course objectives: By the end of the course, the student will: Be able to identify the major component plants of our area and the Pacific Northwest in general; Be exposed to contemporary approaches to figuring out how organisms are related; Recognize the major ecological biomes present in the Pacific Northwest.
5
Grading: There are no formal written exams. Your grade for this course consists of: 1.plant collection project (800 points [100 plants X 8 points each]) 2.field notebook notes (100 points) 3.quizzes (5 quizzes X 20 points = 100 points)
6
Important dates: July 2 nd —1 st class July 30 th —first 50 plants due! August 20 th —last class (last 50 plants due!)

How do we classify life? Kingdom—largest; has most organisms Phylum Class Order Family Genus Specific epithet (‘species’)—smallest;has fewest organisms
9
Example of classification: Dogs Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Canidae Genus: Canis (Latin for dog) Specific epithet : familiaris (Latin for familiar or domesticated)
10
Example of classification: Cats Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Felidae Genus: Felis (Latin for cat) Specific epithet : domesticus (Latin for domesticated)
11
Classification of humans: Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primates Family: Hominidae Genus: Homo Specific epithet: sapiens
12
Rules for scientific names 1. Genus name always capitalized 2. Species name always lowercase 3. Both names underlined or italicized: white rose: Rosa alba chimpanzee: Pan troglodytes humans: Homo sapiens
13
So what is a scientific name? The genus + specific epithet is usually called the scientific name Scientific name is also called species name
14
Scientific names Scientific names are usually abbreviated to the genus and specific epithets Uses the two-name system (genus + specific epithets) reintroduced by Linnaeus (father of taxonomy [naming])
15
How do we show evolutionary relationships? by using phylogenetic (evolutionary) trees These trees start with a common ancestor and show evolutionary shifts into different groups Can apply to any type of organism
16
