Who studied the co-existence of five closely related species of warblers on the same tree?

Options

A. Gause
B. Mac Arthur
C. Darwin
D. Connell

Answer

**Step-by-Step Text Solution:**

1. **Identify the Subject of Study**: The question asks about the co-existence of five closely related species of warblers on the same tree. Warblers are perching birds known for their diverse behaviors.

2. **Understand the Concept of Co-existence**: Co-existence refers to the ability of different species to live together in the same habitat without competing for the same resources. In this case, the warblers share a tree.

3. **Recognize the Mechanism of Co-existence**: The warblers avoid competition by exhibiting different foraging behaviors. Foraging behavior is how animals search for and exploit food resources. By having different foraging habits, these species can reduce competition for food.

4. **Identify the Researcher**: The study of the co-existence of these warblers was conducted by a biologist named Robert MacArthur. He observed how these five species could coexist by utilizing different parts of the tree and different foraging strategies.

5. **Conclude the Answer**: Therefore, the answer to the question is Robert MacArthur.

**Final Answer**: Robert MacArthur studied the co-existence of five closely related species of warblers on the same tree.
