Pipefish have a unique process of reproduction. A female produces hundreds of eggs and deposits them into a male’s brood pouch where they mature. The female then leaves to mate with other males. Once the eggs have matured, the “pregnant” male ejects hundreds of baby pipefish from his brood pouch. 1) Which survivorship curve do pipefish most likely exhibit? [1] 2) Does this pattern suggest that pipefish are an r-selected or K-selected species? [2] Tip: Remember that if you move from the top right to the bottom left of a survivorship graph, you pass through type I, then type II, then type III.

For each example, select either cost of group living or benefit of group living. 1) Increased rate of disease spread. [1] 2) Greater opportunities for offspring care. [2] 3) Increased vigilance as described by the many-eyes hypothesis. [3] 4) High intraspecific competition. [4] 5) Increased visibility to predators. [5]
