Haddad and colleagues conclude that “In our study, we lack data on population viability and genetic diversity, and our dramatic increases in movement to connected patches strongly suggest, but do not demonstrate, the value of corridors.

” (a) Do you think this statement (“suggest, but do not demonstrate”) is a fair assessment of their study? Explain your answer

 (b) What other data are the researchers suggesting they need to conclusively demonstrate the importance of corridors?

 Do you think they are right? For example, does knowing the level of genetic variability answer questions about long-term population survival? 

(c) How could researchers collect these data?
