check answer

Explanation:

• a: The Cactus Ground Finch has a different mating song, which is related to courtship behavior. Behavioral isolation involves differences in courtship, mating songs, or mating activities.
• b: The sperm cannot penetrate the ova. Gametic isolation is when sperm and ova cannot unite to form a zygote.
• c: Red Deer are the European counterpart to the North American Elk. This is ecological isolation as they occupy different geographical (ecological) regions.
• d: Spotted skunks breed in the fall and striped skunks breed in the spring. Temporal isolation is about breeding at different times (in this case, different seasons).

Answer:

1. Ecological Isolation - c
2. Behavioral Isolation - a
3. Gametic Isolation - b
4. Temporal Isolation - d
