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 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 2019 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most organisms undergo ontogenetic changes, leading to complex life histories. An organism’s prey and habitat preferences change as they age, as may their responses to the same environmental stressors. Therefore, a changing environment may confer a competitive advantage to a particular life stage, leading to population structures dominated by one stage or another. I used survey data of brook trout (Salvelinus fontinalis) in lakes across the Sierra Nevada to investigate if there was evidence for (1) alternative stable states between populations dominated by small or large fish, and (2) trends in population structure across elevation to suggest that temperature plays a key role in determining size structure. I characterized the average fish size, number of size classes, and the evenness of the size class distribution for 42 populations. I found these features by fitting a Bayesian normal mixture model using Markov Chain Monte Carlo simulations. I tested for alternative stable states by looking for bimodality in each feature, and I analyzed each feature’s relationship with elevation using Spearman’s rank correlation. I found that that populations are most often dominated by small individuals, rarely by large individuals, and most often contain either one or two distinct size classes. If large individual body sizes occur as an alternative population state, my results show that such populations occurred rarely, or were not well sampled by these surveys. High elevation was associated with reduced average size and greater numbers of size classes, suggesting that temperature does affect size distributions.
