Book excerpt: The population genetic structure of three of the largest walleye spawning groups in Lake Erie is tested for consistency over time and space spanning 14 years, based on nine high-resolution nuclear DNA microsatellite loci. Previous genetic studies focused on a one-time genetic "snapshot", with an earlier study by our laboratory finding that the genetic structure of three Lake Erie spawning groups along the southern shore - Maumee River, Sandusky River, and Van Buren Bay reefs - appeared similar in 2003, whereas most other spawning groups across Lake Erie were genetically distinctive. The present study analyzes the stability of genetic similarity patterns within and among 726 walleye spawning at these three sites across years and age cohorts in 1995, 1998, 2003, 2007, and 2008. Genetic patterns are evaluated using pairwise FST analog and contingency tests, AMOVA partitioning, and Bayesian assignment tests. Results reveal overall year-to-year consistency in genetic structure of walleye spawning at the three sites, with some annual variation in the Van Buren Bay reef group. Greater genetic divergence from the other groups is detected in the Van Buren Bay spawning group, which reflects greater geographic separation. Walleye spawning in the Sandusky and Maumee Rivers are genetically distinguishable from each other when data from all years are combined, which suggests possible sample size effect (i.e., annual sample sizes likely were not large enough to detect their genetic differentiation). No significant differences occur among age cohorts, between the sexes, or among sampling dates within spawning runs. Results demonstrate the importance of sampling over several years of walleye spawning runs in order to resolve fine-scale genetic relationships within an open lake system.

This book was released on 2021-11-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walleye, one of the most sought-after species of freshwater sport fishes in North America, has demonstrated appreciable declines in their numbers from their original populations since the beginning of the 20th century. Similarly, Yellow Perch, once the most commonly caught sport fish and an important commercial species in North America, have also shown declines. Compiling up-to-date information on the biology and management of Walleye, Sauger, and Yellow Perch, including research on systematics, genetics, physiology, ecology, movement, population dynamics, culture, recent case histories, and management practices, will be of interest to managers, researchers, and students who deal with these important species, particularly in light of habitat alterations, population shifts, and other biotic and abiotic factors related to a changing climate.

This book was released on 2013 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding a species' hierarchical genetic variation may provide insights into its ability to cope with current and future stressors, such as climate change, exploitation, and degradation of habitat. Analyzing the events that led to speciation and population diversification may give a framework for predicting responses and adaptations to future changes, imparting critical information for conservation managers. I resolve the evolutionary history and population genetic patterns of the walleye Sander vitreus using molecular and morphological characters and a variety of analyses, including sequences from three nuclear and three mitochondrial (mt) DNA regions and nine nuclear DNA microsatellite (μsat) loci. Results show that walleye and its sister species the sauger S. canadensis diverged ~15.4 Mya (5.2-27.1 Mya = 95% highest posterior density (HPD)), with modern walleye haplotypes differentiating ~10.6 Mya (6.9-14.3 HPD), when climate changes were occurring across North America. Walleye exhibit significant genetic structure (mean FST mtDNA control region=0.24, μsat=0.10) and substantial genetic diversity (mean control region=0.53, μsat=0.68) across its range, at broad- and fine-scales. Contemporary patterns correspond to a genetic isolation by geographic distance hypothesis, with northern populations reflecting differential contribution from three distinct Pleistocene glacial refugia. Comparisons of historic versus modern samples from Lake Erie reveal that allelic frequencies have changed over ~70 years (mean FST control region=0.26, μsat=0.17), with modern populations having higher diversity (mean control region=0.67, μsat=0.72 vs. control region=0.05, μsat=0.47). Today's higher diversity may be due to population rebounds following closure of the walleye fishery in 1970. Paratypes of the historic blue pike did not differ morphologically or genetically from walleye, indicating that the blue pike was not a separate taxon. Additional fine-scale results within the highly degraded Huron-Erie Corridor reveal the seven spawning groups show a mixture of connectivity and divergence. This study also discerns the effects of habitat augmentation on the genetic structure of walleye spawning groups, finding that populations are distinct and have similar levels of genetic diversity (mean control region=0.73, μsat=0.72). Some genetic exchange occurred at an augmentation site, suggesting that walleye from other locations arrived to spawn on the newly available habitat. Such migration could change the genetic composition of the original spawning group. The results of this dissertation provide insight to the processes that shaped the evolution and population genetic patterns of today's walleye, including past climate change, Pleistocene glaciations, and anthropogenic stressors. Future research identifying the adaptations underlying the genetic diversity and divergence patterns discerned here and their respective genetic contributions to fitness will aid efforts to sustain natural populations in the face of ongoing climate change and other anthropogenic stressors.

DuFour and published by . This book was released on 2012 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The estimation of abundance is complicated by factors contributing to spatial and temporal variability. Many organisms are highly variable across both of these scales, thereby violating assumptions of conventional abundance estimation methods. Larval walleye in the Maumee River are extremely variable; however estimates of abundance and mortality are important in understanding anthropogenic impacts on this spawning group and their role in Lake Erie walleye recruitment. Bayesian hierarchical models were used to quantify spatial and temporal variability, and estimate abundance and mortality within the river while accounting for spatial and temporal uncertainty. We sampled larval walleye at the river mouth and in the intake canal of a water-cooled power plant in 2010 and at an additional upstream site near the spawning grounds in 2011. Temporal variability and uncertainty was greater than spatial variability at all sites and years during the study. Daily abundance at each site and year was related to patterns in river discharge and temperature. Larval walleye abundance decreased in a downstream fashion, with an estimated annual natural mortality rate of 63.7% in 2011. Downstream (B) and power plant abundance (C) varied between years leading to a decrease in power plant entrainment mortality from 2010 to 2011, 11.1 to 2.8% respectively. Total in-river mortality was estimated at 64.8% when entrainment mortality was included. Quantifying sources of variability lead to an adjustment in sampling protocol, which increased precision in estimated values. Bayesian hierarchical models provided an optimal framework for understanding sources of variability and estimating larval fish abundance and mortality in this large river system.

This book was released on 2005 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Dam removal is becoming an increasingly popular tool for river restoration throughout the United States. One of the most controversial dam removal proposals in the Lake Erie Watershed involves the Ballville Dam on the Sandusky River (Ohio). The Sandusky River is one of the major spawning tributaries for Lake Erie walleye (Sander vitreus). However, the dam located at river kilometer 29, blocks the fish from reaching upstream gravel beds and forces them to spawn below the Ballville Dam. It has been suggested that removing the dam will increase walleye reproductive success and thus the returning spawning population. This work is divided into two separate studies that focus on different aspects of the impacts the Ballville Dam has on the walleye population in the Sandusky River. An existing ecological model of walleye spawning and early life history stages in the Sandusky River is validated using in-situ egg deposition and larval drift data collected during the 2003 and 2004 spawning seasons. The results indicate that the model results agree with field observations for a spawning population of 2000 to 5000 females. However, this number of females is insufficient to saturate the below-dam spawning grounds, and therefore no increase in egg deposition or larval production is noted for without-dam simulations. A GIS-based habitat suitability model of an area of the currently available spawning grounds in the Sandusky River was also created and validated. The model was able to give a reasonable indication of habitat suitability dynamics in the current spawning grounds. However, there was difficulty resolving velocities in complex areas of the channel. The results indicate that floods with discharges exceeding 100 m3/s can reduce the area of suitable habitat to almost zero. Reproductive success in a given year may therefore rely heavily on the length of the spawning season and the discharge patterns. The results of the two models offer new insight into the removal of the Ballville Dam. However, coupling the two systems (an ecological model and a high resolution habitat suitability model) would give the most complete assessment of the potential impacts of the removal of the Ballville Dam on the walleye population in the Sandusky River.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first unified conceptual and statistical framework for understanding the evolution of reproductive strategies. Using the concept of the opportunity for sexual selection, the authors illustrate how and why sexual selection, though restricted to one sex and opposed in the other, is one of the strongest and fastest of all evolutionary forces. They offer a statistical framework for studying mating system evolution and apply it to patterns of alternative mating strategies. In doing so, they provide a method for quantifying how the strength of sexual selection is affected by the ecological and life history processes that influence females' spatial and temporal clustering and reproductive schedules. Directly challenging verbal evolutionary models that attempt to explain reproductive behavior without quantitative reference to evolutionary genetics, this book establishes a more solid theoretical foundation for the field. Among the weaknesses the authors find in the existing data is the apparent ubiquity of condition-dependent mating tactics. They identify factors likely to contribute to the evolution of alternative mating strategies--which they argue are more common than generally believed--and illustrate how to measure the strength of selection acting on them. Lastly, they offer predictions on the covariation of mating systems and strategies, consider the underlying developmental biology behind male polyphenism, and propose directions for future research. Informed by genetics, this is a comprehensive and rigorous new approach to explaining mating systems and strategies that will influence a wide swath of evolutionary biology.

This book was released on 2011-12-10 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.

Available in PDF, EPUB and Kindle. Book excerpt: When data consist of grouped observations or clusters, and there is a risk that measurements within the same group are not independent, group-specific random effects can be added to a regression model in order to account for such within-group associations. Regression models that contain such group-specific random effects are called mixed-effects regression models, or simply mixed models. Mixed models are a versatile tool that can handle both balanced and unbalanced datasets and that can also be applied when several layers of grouping are present in the data; these layers can either be nested or crossed. In linguistics, as in many other fields, the use of mixed models has gained ground rapidly over the last decade. This methodological evolution enables us to build more sophisticated and arguably more realistic models, but, due to its technical complexity, also introduces new challenges. This volume brings together a number of promising new evolutions in the use of mixed models in linguistics, but also addresses a number of common complications, misunderstandings, and pitfalls. Topics that are covered include the use of huge datasets, dealing with non-linear relations, issues of cross-validation, and issues of model selection and complex random structures. The volume features examples from various subfields in linguistics. The book also provides R code for a wide range of analyses.
