Without own environmental data this is impossible. Species information stored in Internet data bases is often inexact, outdated or from far away geographical areas.

Dear Piyal

Though I never work on the ecological variation analysis methodology, but as a researcher on plant taxonomy I can guess how tough your work is.  actually for any sort of ecological variation analysis or study your own data about the climatic condition of the study area is needed, other wise if you depends on the data available in the internet system may distract your experiment due those data are not accurate in-every sense.  

besides these during analysis of the cytological variation it is also very important to take a grave look on the environmental condition because the expression of the gen often depends on various environmental condition.
