| 1 | <p>This activity includes the data for the proportion of prey captured by three predators (skink, Lampona sp., and Servaea sp.) for each of six species of arthropod prey (along X axis). The five species on the left are mimics with gold coloration on their abdomens to warn predators of their defenses. The non-mimic group (Badumna insignis, a spider) does not display such coloring. The prey species are listed in order of palatability (based on a combination of all defenses, such as spines and chemicals) with the least palatable on the left and most palatable on the right. The first three groups on the left are ants; Daerlac sp. are “true bugs” (order Hemiptera); and Myrmarachne sp. are spiders. Daerlac sp. and Myrmarachne sp. are also ant mimics in terms of their body shape. The three predator species vary in their prey preferences: skinks are lizards that are visual hunter with no feeding preferences among arthropod groups, Lampona sp. are spiders and are non-visual predators that avoids ants, and Servaea sp. are spiders that are specialized ant predators.</p> | 1 | <p>This activity is broken into multiple mini-activities that encourage group work and working individually. Although the content of the article and data being graphed is based on mimicry, students do not need background knowledge in the subject. Rather, this exercise is used by students to help them identify what they don’t know about a graph and address how to fix it. Two of the mini activities are required groupwork (groups between 2-5 students), the next two activities can be assigned as homework and reconvened in groups (or done in groups or individually the entire time), and the final mini-activity is for students to work individually on their new graphs.</p> |
