Data from: Asymmetric geographic range expansion explains the latitudinal diversity gradients of four major taxa of marine plankton
Extensive investigation of the close association between biological diversity and environmental temperature has not yet yielded a generally accepted, empirically validated mechanism to explain latitudinal gradients of species diversity, which occur in most taxa. Using the highly resolved late Cenozo...
