Integrating tradional taxonomy with modern sequencing to reorganise the largest trematode family, the Opecoelidae
My PhD research with the Marine Parasitology Laboratory focussed on the Opecoelidae. With over 900 known species across some 100 recognised genera, the Opecoelidae is the largest of all trematode families. Opecoelids aren't incredibly exciting to look at, even by worm standards: they lack the crazy spines and tentacles seen in some other lineages and, despite their richness, morphological variation within the group is limited. This lack of morphological diversity has resulted in a history of confusion around classification among opecoelids; many genera are poorly defined, and some have even been termed 'waste-baskets,' dumping grounds for poorly described or especially generalised species.
I attempted to resolve these systematics issues, by combining morphological study with DNA sequence data analyses for as broad a sample of opecoelids as possible. I found that not only are many opecoelid genera polyphyletic and in need of revision, but also that the subfamily level arrangement of the family was inadequate. I revised several important species and genus concepts, discovered and described 20 new species and 9 new genera and proposed dramatic changes at all levels of classification within the family. Following my investigations, the subfamily organisation of the family is now much more satisfactorily consistent with phylogenetic, morphological and ecological evidence, although my research has also established important groundwork for myriad further investigations.
I have been fortunate enough to have my PhD studies supported by the Australian Biological Resources Study (ABRS), the Holsworth Fund and the Ecological Society of Australia, the PADI foundation, the Australian Society for Parasitology (ASP), and the School of Biological Sciences and the Graduate School at the University of Queensland, in addition to the Australian Government's APA scholarship. Support from these institutions has greatly increased the scope and impact of my research, providing me with increased opportunity to conduct field collection, attend international conferences and generate DNA sequence data.
