Tom JM Van Dooren, Henri A Thomassen, Femmie Smit, Andrew J Helmstetter, Vincent Savolainen
The paper tests two hypotheses for the evolution of large piscivorous killifish in Austrolebias using phylogenetic and biogeographic analysis, finding support for sympatric giant-dwarf speciation in some clades.
