The research aims to understand how \u03b1 diversity (the diversity within individual plant species) and \u03b2 diversity (the diversity among different plant species at each site) are influenced by latitude. Given the information arms-race between plants and parasites, it is expected that as latitude increases, \u03b1 diversity may decrease due to harsher conditions and fewer species, while \u03b2 diversity may increase as different species adapt to varying conditions. Therefore, the most likely answer is that \u03b1 diversity is negative and \u03b2 diversity is positive."}
