▼ Gastropod immunobiology has benefitted from investigations focused on the planorbid snail Biomphalaria glabrata, intermediate host for the human parasite Schistosoma mansoni. Though such concentrated efforts have elucidated fascinating aspects of invertebrate immunity, they have not provided full knowledge regarding the evolution of immune function among other gastropod species. This dissertation presents the importance of making strategic choices regarding which organisms to select for comparative immunology. Herein, the choice was made to investigate the immunobiology of Physella acuta, a freshwater snail species of the Physidae, a sister family to Planorbidae to which B. glabrata belongs. Benefiting greatly from the use of next-generation sequencing (NGS), the immunobiology of P. acuta was studied using 454 pyrosequencing, Illumina RNA-seq, experimental infections with Echinostoma paraensei (trematode parasite), and other molecular techniques. These analyses revealed that many components of gastropod immunity have been conserved among physid and planorbid snails. Also, P. acuta displays differences in immune function, such as the use of fibrinogen-related proteins in response to trematode parasite exposure. Remarkably, P. acuta differentially expressed relatively large immune-relevant gene families (CD109/TEP, dermatopin, GTPase IMAP, among others) after exposure to E. paraenesi. Inspection of the individual members that represent these gene families demonstrated complex transcriptional profiles that suggest parasite influence on host immune function and the capacity of a host to maintain homeostasis while supporting parasite development, an extended phenotype of E. paraenesi. These lab-based studies represent the first large scale characterizations of P. acuta immune function. The immune factors described through NGS approaches enable investigations of the ecoimmunology of P. acuta snails collected from the field. This approach uncovered many sequences that are differentially expressed by P. acuta naturally in the field relative to the lab environment. There is variation in the expression of certain antimicrobial factors and genes governing biological processes. Overall, this dissertation has expanded the scope of gastropod immunity and provides resources and insights that are accessible for continued development and understanding of evolutionary and comparative immunology concepts.

1. Introduction – 2. Status of the Sydney rock oyster in a disease-afflicted estuary: persistence of wild populations despite severe impacts on culture counterparts – 3. Are native Saccostrea glomerata and invasive Crassostrea gigas oysters habitat equivalents for epibenthic communities in south-eastern Australia? – 4. Substrate or sink? Differences in settlement of Saccostrea glomerata larvae on non-native Crassostrea gigas and conspecifics is determined by spatial arrangement – 5. Differences in the shell strength of native and non-native oysters do not influence their susceptibility to a generalist predator – 6. General conclusions.

As a consequence of rising global consumption of seafood and over-extraction of wild finand shell-fisheries, aquaculture is the fastest growing food production method in the world. Although in some instances aquaculture may benefit wild populations by deflecting harvest pressure away from these, in others it may have negative impacts as a consequence of facilitation of disease or biological invasion or where it results in genetic pollution of wild populations with selectively-bred genotypes. The oyster industry of New South Wales (NSW), Australia, is presently entirely dependent on aquaculture. Although the NSW industry historically cultured wild-caught native Sydney rock oysters (Saccostrea glomerata), in recent years high mortality of cultured oysters from QX disease has led to a shift towards culture of Sydney rock oysters selectively bred for disease resistance and non-native Pacific oysters (Crassostrea gigas) that are unaffected by the disease. It is unknown how QX disease or the resulting strategies of management that have been applied to the aquaculture industry (culture of disease resistant Sydney rock or Pacific oysters) may impact wild populations of Sydney rock oysters, and their important ecosystem services, which include provision of habitat and food for associated communities of fish and invertebrates. This thesis determined: (1) how QX disease has impacted wild populations of Sydney rock oysters, both directly and indirectly as a result of any facilitation of Pacific oysters, and (2) whether wild-stock Sydney rock oysters, disease resistant Sydney rock oysters, and Pacific oysters are functionally equivalent in their provision of habitat and food to associated communities of invertebrates. – Sampling in the Hawkesbury River, NSW, where QX disease has produced aquaculture mortality of Sydney rock oysters of up to 90%, revealed only a low (<14%) prevalence of the disease-causing parasite among wild Sydney rock oysters on rocky shores. Consequently, mortality rates of wild Sydney rock oysters remained low and there was no evidence of replacement of populations of Sydney rock oysters with disease-resistant Pacific oysters. Field and laboratory experiments showed that even under the scenario that aquaculture facilitates invasion of Pacific oysters or causes genetic modification of wild Sydney rock oyster populations, little change…
