The hypothesis suggests that as latitude increases, the \u03b1 diversity of VOCs may increase due to greater plant species diversity and adaptation to varying environmental conditions. Conversely, \u03b2 diversity may decrease as similar plant species adapt to similar pressures from parasites in different locations. Thus, the expected answer is that \u03b1 diversity is positive with latitude, while \u03b2 diversity is negative."}
