1 BIOLOGY 321 FIELDTRIP TO BEATY MUSEUM Station 1. Human uses of mosses (Cabinets , , ) Part A. Go through the displays at your station and answer the following questions. How many species of bryophytes are found in British Columbia? Granite moss (Andreaeaceae) diverged early in the evolution of mosses. Identify features of granite mosses (from the pictures) that are different from the Bryopsids we have learned about. Name two mosses commonly found in lawns. Examine the displays having to do with human uses of moss. Can you think of features of mosses that make them useful in the flower industry and as pollution indicators? Part B. Critique the displays at your station. (Is there inaccurate information, wording that could be improved, information lacking, etc?)
2 Part C. Treasure hunt questions (Finish as many as possible while time allows). Who is the most prominent bryologist and collector in the herbarium? In the evolution of mosses, Takakiaceae, Sphagnaceae, Andreaeaceae, and Andreaeobryaceae are the first ones that diverged. How many genera does each family have? How do their sporangia dehisce (open) to release spores? Find the diagram showing the moss life cycle. Can you find the error(s)? What family do dung mosses belong to? What are the advantages/disadvantages of their life style? Name the functions of mosses (two human uses and two in the ecosystem). The dominant plant in Camosum bog (in Pacific Spirit park) is Sphagnum. How many species of Sphagnum are found there? There is a timeline on the side wall showing the evolution of life on earth. When did land plants arise? Find the picture of Ying!!!!
3 BIOLOGY 321 FIELDTRIP TO BEATY MUSEUM Station 2: Land- plant evolution (Cabinets , , , ) Part A. Go through the displays at your station and answer the following questions. What is the scientific name for the snake moss? Part of your display is on land- plant evolution (the display between cabinets and 19.04). According to the display, which bryophyte group diverged first? Which bryophyte group is the closest relative to tracheophytes? There are two definitions of plants mentioned in the display. Which one do you prefer? Why? What plant structure is the earliest land- plant fossil? Why are there very few fossils of other parts of early land plants? Identify adaptations of mosses to terrestrial life. Part B. Critique the displays at your station. (Is there inaccurate information, wording that could be improved, information lacking, etc?)
