Study guide: Lecture 5 INTERSPECIFIC COMPETITION: PART II – POSSIBLE OUTCOMES Text reading: Red/Black Campbell (7 th ed), pgs. 1164, 766-767, 620, 1159-1161, 1164 Black/Green Campbell (6 th ed), pgs 1180-1181, 628-629, 778-779, 1176-1177 (Note: You may have read these pages previously).

The small streams that you see flowing through Oregon Ridge Park and elsewhere in the northeast U.S. contain a small aquatic salamander known as the two-lined salamander. Imagine that a small population of a second species of aquatic salamander from South America is introduced into the stream by a deranged herpetologist. The South American salamander requires some of the same resources (insect prey, egg hiding spots, etc.) as the native species. a) Assuming that the two species will compete for one or more limited resources, what are the possible outcomes of competition between the two salamander species? b) In theory, what two factors will ultimately determine the outcome of competition between the two
