Lab Unit 8 – In Person – work in progress

Species Relationships: Symbiosis

Scroll below for In-Person Labs

Interspecific interactions: Interactions between organisms of different species (deer and cattle).
Intraspecific interactions: Interactions between members of the same species (interactions within a deer population).
Mutualism: a relationship between two species of organisms in which both benefit from the association.
Commensalism: A symbiotic relationship between two organisms of different species in which one derives some benefit while the other is unaffected.
Parasitism: A symbiotic relationship in which one organism (the parasite) benefits and the other (the host) is harmed. Parasites derive nutrition from their host and may also gain other benefits such as shelter and a habitat in which to grow and reproduce.
Endoparasites: A parasite, such as a tapeworm, that lives within another organism.
Ectoparasites: A parasite, such as a flea, that lives on the exterior of another organism

Review the lab manual pages, pp. 130-132, and use the information below to learn about pollination strategies:
- Video describing various Pollination: Trading Food for Fertilization.
- Flower Traits Slide Show
- Match Flower and Pollinator
Review the Links below for additional information on pollination and to help you with the In-Lab and Post_Lab Assignments.

Review the lab manual pages, pp. 130-132, and use the information links above to learn about different pollination strategies.
A wide variety of flowers will be available in lab for viewing. Each student should fill in Table 8-2 for 5 flowers found in the lab room. Use Table 8-1 to help you with your predictions and justifications.
Each group will make a unified presentation using Google Slides. Each student will select one of their flowers, take a picture of it and work on creating a slide to add their their group’s Pollination Presentation.
Your TA will provide a Google Slides Template for your presentation.
Each presentation should include a picture of each flower, scientific name/common name, the predicted pollinators, and supporting information to justify your prediction.
A few groups will be randomly selected to present their presentation.
Turn your Pollinator Presentation in on Moodle (1 per group).
Making presentations will help you build skills for the Post-Lab and your final Experimental Design Project presentation.

Follow the lab manual directions on pages, 133 & 134 to prepare slides and view the Symbiosis in Termites (Act. Two) and Bacteria and Protists found in Cow Rumen fluid (Act. Three).
Termite Gut Microbes(opens in new window) – images of a variety of microbes Univ. of Conn. research lab.
Microbial Symbiosis in Cow Rumen(opens in new window) – ppt
Pandas – another example of the importance of bacteria endosymbiosis(opens in new window)(opens in new window) – Short article about the bacteria found in Panda feces and inserting them into yeast to increase biofuel efficiency. You will learn more about this technology in BIO 183 labs.

Draw a few of the endosymbionts that you see in your lab manual (p. 133 and 134). Be sure to label if these are form the termite slide or the rumen fluid.
You will need to include pictures of these sketches in the provided In-Lab assignment.

Answer the questions and provide jpg or pdf pictures of your endosymbiont drawings of the symbionts on the attached In-Lab Worksheet. These questions encompass informations from Activities One – Three.
This is individual work and your answers should be written in your own words and not copied from the lab manual or the internet.
Upload your completed In-Lab Worksheet as a pdf in Moodle.

To further your knowledge of biodiversity, your Lab Group will become experts in 1 group of Endoparasites and one group of Ectoparasites. You will do this completely outside of lab.
BE SURE to agree upon a due date to complete your work and who will be turning it in 48 hours after lab this week.
Be sure to do all your work within the provided Google folder so your TA can track participation.
Refer to page 135 in your lab manual to see all of the parasite groups we will be studying. Note your assigned Table Group (see Table 8-3 in your lab manual). Seven of these groups were represented in the Invertebrate Phyla studied last week in lab (Unit 7 Fungi Invertebrate lab). Which groups? What Phyla do they belong in?
One pair of students will be assigned to explore an Endoparasite group and the other pair will be in charge of the Ectoparasite group.
Click the Parasite Webquest Activity and Assignment yellow box below. Explore your groups by following the series of weblinks within your assigned groups. Click as many of the links that you can to help you find pertinent information needed in your presentation.
Each student is responsible for compiling information on their assigned group by selecting a representative organism in that sections. Be mindful to select different organisms to highlight in the presentation.
Once complete, the group will upload 1 complete Google slides presentation on Moodle.
