What are the motifs in The Short, Happy Life of Francis Macomber by Ernest Hemingway?

A reoccurring idea in the story is survival In the wilderness. The Macombers, wealthy urban people, would not be able to survive alone in the wilderness, so they hire a guide to help them with their hunt. Ironically, the presence of a guide does not protect Francis Macomber but compels him to assume a persona of bravado that leads him to his death. Macomber struggles with his position within the wilderness, wondering if it is more honorable to be like Wilson or to heed his instinct for self-preservation by fleeing from wounded animals.
