Question
Paleobotany make us able to understand about the plants of the world that existed in the history and thus help giving an idea about the phylogeny of plants and the climate that was predominant at that particular time. But what would be the benefits of knowing about these areas?
Question
I am currently working on a project on herbivory and grasslands, but am unable to find proper review. Please help me in finding people who have done some sort of work in herbivory and grasslands management.
Best regards,
