Description: Issues regarding the specific and subspecific make-up of each of the stickleback genera have a long history in the literature. While the monophyly of the sticklebacks has been established, to date there has been no total evidence phylogeny for the family to determine the relationships between the species. The relationships within the Gasterosteidae was investigated using 3011 molecular, morphological and behavioural characters. One tree of 2241 steps was found with the relationships (Spinachia( Apeltes(Gasterosteus(Pungitius+ Culaea)))). The specific composition of Culaea and their biogeographic history was further investigated using three mitochondrial genes in a phylogeographic analysis. The genus was found to comprise three, possibly four, genetic lineages. The biogeographic analysis indicates that some of the diversity uncovered within Culaea predated the Pleistocene glaciations, while some was likely the direct result of glacial advance and retreat.
