Monarch butterflies are commonly found throughout the bulk of the United States during most of the year, but primarily spend the winter months in central Mexico. The butterflies can tolerate temperatures as low as about 40 degrees Fahrenheit, unless conditions are also rainy. Under wet conditions, the butterflies require warmer temperatures in order to maintain their body temperature. The butterflies spend the winter roosting in large clusters that hang from mature conifer trees. This clustering helps the butterflies maintain their body temperature, and avoids the dangers of roosting on the ground, where they might be susceptible to danger. Consequently, the butterflies can only overwinter in areas with mature trees, which have been reduced throughout the area due to logging. Which of the following statements are true of the monarch butterflies’ overwintering niche? (Select all that apply) A. The butterfly’s realized niche includes regions with lower temperature and precipitation than the fundamental niche B. The butterfly’s fundamental niche contains only areas with mature conifer trees C. The butterfly's realized niche is affected by logging D. The butterfly’s realized niche is reduced compared to its fundamental niche E. The butterfly’s fundamental niche is driven by temperature and precipitation
