Cembrola and published by . This book was released on 2014 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of genetic markers in monitoring populations has become increasingly important for conservation purposes, and can take many forms. While effective population size (Ne) is of great interest to conservation genetics, it may be much easier and more practical to estimate the effective number of breeders (Nb) per cohort as a tool for genetic monitoring of populations. Few studies have estimated Nb for the same species over long periods of time in comparison with demographic or environmental variables. I estimated Nb of the eastern brook trout, Salvelinus fontinalis, as part of long-term studies of two stream systems: West Brook (WB) in Massachusetts and Stanley Brook (SB) in Maine. I used eight microsatellite loci for all available young of the year (YOY) from each cohort in WB and a random subset of YOY distributed evenly throughout SB to obtain genetic-based estimates. I estimated adult abundance (NC) from mark-recapture data, and used seasonal stream flow as an environmental variable. I performed linear models with Nb as the response variable and family structure (number of families and variance in family size), NC, and seasonal stream flow as predictor variables. I found that both the number of families and variance in family size had a strong influence on Nb. Compared to abundance of adults and YOY, Nb was relatively stable over time.Stream flow in both autumn and spring showed a quadratic relationship with Nb in WB, suggesting that intermediate flows are optimal for maintaining a higher Nb. SB, with fewer years of data, did not show these relationships. If incorporated into monitoring programs, Nb can be a useful tool for detecting changes in population status and for informing management decisions.

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 2015 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Non-native salmonids have been stocked into the Great Lakes since the 1870s and now naturalized populations use tributary environments to reproduce and for their juvenile life stage. Historically, brook trout were the only salmonid to inhabit the tributary environment and numerous studies suggest that exotic salmonids negatively affect brook trout by competing for limited resources. Other studies have been successful at removing non-native salmonids and the native populations increased. During this project 5,320 exotic salmonids were removed from a tributary of Lake Superior from 2008 to 2010 significantly reducing their density and young-of-year brook trout density increased by 260% the year after the study suggesting interspecific competition may be occurring. In order to monitor the salmonid populations closely, three techniques were used to assess population size of this small brook trout population. Mark-recapture estimates had large confidence intervals, so changes in population size could not be detected. Depletion estimates were hampered by sample size constraints and likely underestimated the population size. Relative abundance seemed to be the least likely to be biased because sampling was done on a frequent basis, which helped identify apparent changes in capture probability making it the best option to monitor changes in population size."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.
