HUMAN INTERVENTION AND BIODIVERSITY VIDEO (PLANET EARTH) |
1. Reflecting from the video, list several actions that have lead to the decline of biodiversity on earth. For each action (e.g. poaching) provide an example. (K/U)
2. Explain how poverty and conflict impact conservation efforts in many nations worldwide by using examples from the video. (APP)
3. What is biodiversity? (K/U)
4. Why should we preserve biodiversity on Earth? (T/I)
5. List various strategies we can use to preserve biodiversity on Earth. For each strategy discuss an advantage and disadvantage. (APP)
Method | Advantage | Disadvantage | | | | | | | | | |
HOW DO WE CLASSIFY LIFE? |
6. Indicate which definition of a species (biological (reproduction), morphological (shape) or phylogenetic (DNA)) is illustrated in each example. (T/I)
Example | Type of Species Concept (Biological, Morphological or Phylogenetic) | A migratory herd of caribou mixes with a second migratory herd of caribou. | | The monarch butterfly and viceroy butterfly look almost identical. | | Through recent discovery scientists have determined that birds share a closer evolutionary relationship with dinosaurs than reptiles. | |
7. Use the table below to answer the following questions (T/I)
Common Name | Scientific Name | Family | Eastern garter snake | Thamnophis sirtalis | Colubridae | Painted turtle | Chrysemys picta | Emydidae | Eastern massasauga rattlesnake | Sistrurus catenatus | Viperidae | Snapping turtle | Chelydra serpentine | Chelydridae | Spotted turtle | Clemmys guttata | Emydidae | Smooth green snake | Opheodrys vernalis | Colubridae | Musk turtle | Sternotherus odoratus | Kinosternidae | Ringneck snake | Diadophis punctatus | Colubridae | Eastern ribbon snake | Thamnophis sauritus | Colubridae |
a. Which pair of species is the most closely related pair? Explain.
b. How many families are represented by the four turtle species? List each one.
c. How many families are represented by the five snake species? List each one.
d. Is the spotted turtle more closely related to the painted turtle or the musk turtle? Why?
e. What error has been made in the formatting of the scientific names? What should have been done?
READING AND DETERMINING PHYLOGENETIC RELATIONSHIPS |
8. Use the illustration at the right to answer the following questions:
a. Which groups of organisms share a common ancestor with one another? (T/I)
b. Which organism is most closely related to a tutara? (T/I)
c. Which organism is most distantly related to the tutara? (T/I)
DICHOTOMOUS KEYS |
9. Create a dichotomous key to distinguish the following organisms from one another: Dove, worm, perch, daffodil
10. Use the key in the table below to identify the organism in the image. (You may want to look at the image on the Moodle to see the colour of the lizard's spots) (APP)
1a. Skin without spots...go to 2 | 1b. Skin with spots....got to 4 | 2a. Found under cover in or beside streams... two-lined salamader | 2b. Found in forests... go to 3 | 3a. Red stripe down back... red-backed salamander | 3b. Grey-black overall.... red-backed salamander (black variant) | 4a. Bright red small spots... go to 5 | 4b. Blue or yellow spots.... go to 6 | 5a. Green overall, found in aquatic ecosystems... red-spotted newt | 5b. Reddish overall, found in terrestrial ecosystems... red-spotted newt juvenile ("red eft") | 6a. Many irregular blue spots ....blue-spotted salamander | 6b. Large yellow spots...yellow-spotted salamander |
INTRODUCING THE SIX KINGDOMS |
11. Make sure you have your handout on the six kingdoms filled out from our "food" activity day. If you don't have it filled out get the answers from a peer.
12. Create a graphic organizer (e.g. mini mind map) to show the different domains and kingdoms. For…
