Textbook Question
Chapter 1, Problem 13PIAT
Quantitative Researchers hypothesized that leaf mimicry by B. trifoliolata provides protection from plant-eating animals (herbivores). The results of a study of 45 individual vines are shown in the following graph. Light conditions were very similar in all cases. Researchers compared the level of leaf damage by plant eaters (herbivory index) in vines climbing leafy host trees, vines creeping on the ground with no support, and vines climbing on bare tree trunks. Use the P values provided to determine if the differences are significant or not (*** means P < 0.001, see BioSkills 3). What conclusion, if any, can be drawn about leaf mimicry from this study? What might the researchers do next to further explore the role of leaf mimicry?

You've been out in the field collecting data on the predation of holly leaves. You collect 200 leaves in total of which 100 leaves contain one mine, 20 leaves contain 2 mines and 30 leaves contain 3 mines. After close examination with your hand lens and dissecting microscope you categorize a total of 15 mines with round holes, 9 mines that were torn open and 27 mines with an irregular hole. After some basic analyses you conclude that the predation rates by blue tits and wasps are:
Â
A.
3.7% and 6.5%
Â
B.
6% and 10%
Â
C.
10% and 6%
Â
D.
4% and 6.5%
According to the article, frugivores affect their food plants and the plants' communities by: (Choose one.)
Group of answer choices
Â
a.increasing dispersal of plant pathogens, which changes the composition and abundance of plant communities.
Â
b.preying on seeds of plants, which decreases the survivorship of plants and pushes their populations to extinction.
Â
c. increasing dispersal and germination of the plants, which influences the composition and abundance of plants in communities.
Â
d. increasing pollination of plants, which increases the abundance of plant hybrids in their communities.

- Make a simple model illustrating how tomato plants might be able to detect insects on a neighboring plant and protect themselves from infestation and how the components of this system interact. Show how fungi transfer information from insect-infested tomato plants to nearby uninfested tomato plants. Be sure to label any inputs and outputs in the model.arrow_forwardHow do the authors of the study interpret the information shown in Figure 3? (Choose one.) Group of answer choices The speed (number of days) at which fig saplings die from wilting disease is much faster when the saplings are inoculated with two species of fungi at the same time, compared to only one of the species. The number of days which saplings survive is significantly longer when fig saplings are inoculated with C. ficicola and F. kuroshium at the same time, compared to just inoculated with C. ficicola. There were significantly higher densities of C. ficicola than of F. kuroshium found in plants suffering from fig wilt disease. The number of saplings dying from fig wilt disease was significantly higher in plants inoculated with C. ficicola than in plants inoculated with F. kuroshium plus C. ficicola.arrow_forwardIf raising honeybees as pollinators becomes unprofitable because of colony collapse, what alternatives do farmers have?arrow_forward

At the end of the experiment the plants were cropped by cutting the stems at the soil surface.
