The flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?

• behavioral isolation
• hybrid sterility 
• temporal isolation
• mechanical isolation

• hybrid sterility 
• temporal isolation
• mechanical isolation
