C): including genetic analysis of P. microdon across northern Australia https://web.archive.org/web/20120601194551/http://environment.gov.au/coasts/publications/pubs/freshwater-sawfish-northern-river-shark.pdf This indicates that the present levels of genetic diversity in P. microdon are not unusually low, although the amount of diversity to be expected in pristine populations of coastal species of elasmobranch remains elusive because all populations investigated to date have suffered some degree of decline (e.g. Sandoval-Castillo et al. 2004, Keeney et al. 2005, Hoelzel et al. 2006, Stow et al. 2006, Lewallen et al. 2007).
