Mathematical descriptions of the growth of animals are reviewed in the light of applicability to two species of the Family Salmonidae. No generalized growth equation is found to accurately depict growth for the material discussed. Theoretical and practical limitations of the use of age as a classification for relating growth rates are given. An hypothesis that relative growth rate declines with increase in size but is independent of age is offered and explored. Data on steelhead from Chilliwack River, British Columbia, are analysed with the use of size-specific instantaneous growth rate regressions. Factors leading to observed variation and life history events are discussed and the literature reviewed. In all cases, size is determined to be a more reliable criterion of physiological development than age. / Science, Faculty of / Zoology, Department of / Graduate

The role of ephemeral swamps and intermittent tributaries (off-stream habitat) located on the flood-plain of a west coast Vancouver Island stream (Carnation Creek), as over-wintering habitat, was examined for two winters. All trout (Salmo gairdneri and S_. clarki clarki) and juvenile coho salmon (Oncorhynchus kisutch) off-stream habitat were identified and characterized. Within this habitat: seasonal movement of salmonids was noted, coho growth rates were measured, salmonid populations were enumerated and contribution of off-stream habitat to the total coho smolt production was estimated. Coho and trout did not occupy all winter flooded land. Trout occupied intermittent tributaries, while coho occupied both intermittent tributaries and ephemeral swamps. Salmonid use of flooded meadows was negligible. The contribution of off-stream habitat to the watershed's total smolt production was at least 23% and more than 15% came from sites devoid of water in summer. Seasonal movement of juvenile coho followed a distinct pattern and appeared dependent upon climatic conditions such as magnitude and timing of the first fall (Oct-Nov) freshet. Climatic conditions in spring (March-May) appeared to influence both growth and survival of coho within one small ephemeral swamp. / Forestry, Faculty of / Graduate

Whole genome duplication (WGD) is thought to promote evolutionary diversification via the divergence of retained duplicate genes (ohnologues), which occurs during the post WGD rediploidization process. The long-term evolutionary consequences of the rediploidization process for ohnologue evolution remains poorly characterized. In salmonid fishes, the rediploidization process is yet to be fully resolved since an ancestral WGD event (Ss4R) ~95 Mya. This group of fishes provides an ideal system for investigating the link between WGD, rediploidization and evolutionary diversification. However, the sequence resources available for salmonids remains restricted to a few lineages. The overarching goal of my thesis was to generate new genomic resources for salmonids to study the evolutionary consequences of Ss4R in the broadest possible phylogenetic framework. Using targeted sequence capture, large amounts of high-quality data was obtained across the salmonid phylogeny, allowing high-resolution phylogenomic investigations. This approach was successful in recovering thousands of protein-coding sequences, including a rich representation of ohnologues. The resultant dataset was thoroughly validated and used to test a newly proposed model - 'lineage-specific ohnologue resolution' (LORe) – to address the evolutionary consequences of delayed rediploidization. Under LORe, speciation precedes rediploidization, allowing independent ohnologue divergence in sister lineages sharing an ancestral WGD. LORe was characterized by reconstructing the rediploidization histories of Hox gene clusters retained from Ss4R and using a phylogenomic approach exploiting the Atlantic salmon genome as reference. This study provided strong empirical support for LORe and revealed its role as a significant source of lineage-specific sequence variation after Ss4R, The broader implications of LORe for our understanding of eukaryotic genome evolution were also considered on multiple levels. The sequence capture data was also utilized to characterize the post-Ss4R evolution of the insulin-like growth factor system at unprecedented phylogenetic resolution. This work demonstrated that it was possible to build complete protein-coding genes from sequence capture data that can correctly distinguish and identify new Ss4R ohnologues. As a result, I was able to characterize the historic selection regimes driving sequence divergence in IGF system ohnologues, which will be a useful approach in future investigations. Overall, my thesis demonstrates that targeted sequence capture offers a viable alternative to whole genome sequencing to investigate genome evolution in salmonids. While genome sequencing projects are underway or nearing completion for many salmonids, it is concluded that sequence capture still has a place in the ongoing research of these societally important fishes.
