This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Population genetic evidence suggests differentiation among evolutionarily significant units of southern and northern Appalachian brook trout, with the zone of contact in southwestern Virginia. Before this differentiation was recognized, brook trout of northern origin were stocked throughout the southeastern United States. In order to determine this differentiation, established allozyme markers were used to classify 56 southwest Virginia populations as southern, northern, or introgressed. Variation at 4 polymorphic loci, including the diagnostic creatine kinase (CK-A2*) locus, indicated that 19 populations were of southern origin, 5 of northern origin, and 32 of mixed genetic origin. Data compiled among genetic studies of brook trout in the southern Appalachians showed that the southern/northern break is sharp, occurring at the New/Roanoke-James watershed divide. New River drainage populations exhibited the southern allele at high frequency, suggesting their historic native character as southern, with presence of northern alleles due to stocking or stream capture events. In conclusion, the present study suggests that management of southern Appalachian brook trout should include: (1) genetically cognizant planning of stocking events, (2) management of populations on a stream-by-stream basis, (3) prioritized conservation of pure southern brook trout populations, and (4) use of southern Appalachian hatchery stocks in restoration efforts.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the drivers of successful species invasions is important for conserving native biodiversity and for mitigating the economic impacts of introduced species. However, whole genome resolution investigations of the underlying contributions of neutral and adaptive genetic variation to successful colonization in introduced populations are rare. Increased propagule pressure should result in greater neutral genetic variation, while environmental differences should elicit selective pressures on introduced populations, potentially supporting greater adaptive genetic variation. We investigated neutral and adaptive variation among nine introduced brook trout (Salvelinus fontinalis) populations using whole-genome sequencing (28,490,618 SNPs based on pool-seq). The populations inhabit different, isolated lakes in western Canada and descend from a common source, with an average of ~19 (range of 7-41) generations since introduction. We found no evidence of bottleneck events nor strong evidence of purifying selection, and little support that varying propagule pressure or differences in local environments shaped neutral genetic variation. Putative outlier analysis revealed non-convergent patterns of adaptive differentiation among lakes with minimal outlier loci (0.001%-0.15%) which did not correspond with tested environmental variables, despite conditions that should facilitate stronger adaptive differentiation (e.g. abiotic and biotic environmental differences, propagule pressure differences). Our whole genome sequencing analysis provides an example of an introduction success not strongly influenced by genetic variation and suggests that observed differentiation among introduced salmonid populations can be idiosyncratic, population-specific, or stochastic.

This book was released on 2013 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focused on four tributaries located in Pictured Rocks National Lakeshore: Miners River, Mosquito River, Sevenmile Creek, and Hurricane River. Eight microsatellite loci were used to examine genetic diversity and structure between groups of brook trout. Brook trout were sampled in Open and Restricted sections from each tributary for wider comparisons between groups. Open designated sections are the downstream portion of the tributary with access to Lake Superior, whereas each Restricted section is the upstream portion above a barrier to fish movement (i.e. waterfall). Adfluvial brook trout were classified from PIT tag movement data from two of the streams (MOS and SVN). Abundance of classified adfluvial (coaster) brook trout, individuals that utilize both stream and lake environments, varied between streams (MOS=35 to SVN= 106). The results showed that adfluvial brook trout were more closely related to the fluvial brook trout from their stream of capture than to other designated adfluvial groups. All Restricted sections of rivers were most closely related to their Open section counterparts, with the exception of Hurricane Restricted which was most closely related to Sevenmile Open. Within the Restricted sections there was moderate genetic differentiation between all tributaries. Miners River was the most genetically distinct population overall followed by Mosquito River, which showed levels consistent with higher interaction rates between other tributaries. Sevenmile Creek and Hurricane River are the most genetically similar populations. This suggests that there is more movement of brook trout between Sevenmile Creek and Hurricane River than between the other sites in PIRO. I suggest that the movement of adfluvial brook trout between systems is the most likely explanation for these patterns and inter-stream movement is driving the genetic dynamics found across the population.

This book was released on 1996 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Divergence and speciation among highland ichthyofauna of the Mississippi River drainage has been the focus of numerous investigations. This thesis explores the modes of differentiation and speciation among some etheostomid darters of the Central Highlands. Hypothesized modes of divergence were constructed based upon changes in North American drainage patterns inferred from geological evidence. AmtDNA molecular phylogeny was constructed from Etheostoma blennioides and members of the Etheostoma variatum species group. This phylogeny was used to test hypothesized modes of divergence among the two groups. Each mode of divergence predicted a particular phylogenic relationship among taxa. The "real" tree was compared to each hypothetical tree in order infer how the taxa diverged. In addition, a nested analysis was used to infer modes of divergence at an intraspecific level. Within the Etheostoma variatum species group it was found that E. blennius did not form a monophyletic clade which proved to be as divergent from each other as they were from other species within the variatum species group. Conversely, E. kanawhae was paraphyletic with respect to E. osbumi, the two species show minimal differences. Among the sub species of E. blennioides, E.b. newmanii contained two distinct clades, one on each side of the Mississippi River. Divergence with the Etheostoma variatum species group was caused by a combination of factors. The southern highland drainages diverged from the northern drainages prior to the Pleistocene. Speciation in the northern highland drainages was brought about by vicariance due to the advance of glacial ice sheets, and the formation of pro glacial lakes, during the Pleistocene. Populations of E. blennioides in the southern highland drainages diverged from northern populations prior to the Pleistocene. Northern highland populations of E. blennioides diverged east and west of the Mississippi River. Changes in the character of the Mississippi during the Pleistocene made it impassible to highland fauna such as E. blennioides. Ecological differences between these two groups of etheostomid darters caused them to respond to the same environmental factors in qualitatively different ways.
