Short summary
We evaluated how freshwater ostracode species responded to long-term and abrupt climate fluctuations during the last 155 kyr in the northern Neotropical region. We used fossil records and species distribution modelling. Fossil evidence suggests negligible effects of long-term climate variations on aquatic niche stability. Models suggest that abrupt climate fluctuation forced species to migrate south to Central America. Micro-refugia and meta-populations can explain survival of endemic species.
