Climates fluctuated in the course of this time, forcing vegetation in all aspects of the world to continuously migrate, by seed dispersal, to achieve regions of suited local climate. Not all vegetation ended up equipped to do this equally nicely due to the fact some experienced fewer-helpful means of seed dispersal than Other people. Several extinctions resulted. In the course of the most Serious durations (the glacial maxima, when climates ended up at their coldest and, for most areas, also driest), the variety of tropical rainforests shrank to its smallest extent, starting to be limited to somewhat compact refugia.
