Book excerpt: A smallmouth bass habitat model was developed to estimate how changes in habitat may affect smallmouth bass populations. Habitat characteristics such as mean annual air temperature and substrate were used to determine the spatial distribution of nests, juveniles and adults throughout a lake. Growth is density-dependent for all life stages. Mortality is size-dependent in the young-of-the-year (YOY) but is set at a constant annual rate for older fish. Sensitivity analyses revealed that increases in mean annual air temperature, total dissolved solids concentration and the area available for nesting increased the density of the simulated population. Furthermore, a YOY bottleneck exists in smallmouth bass populations and the nesting habitat appears to be more important than the juvenile/adult habitat. Model predictions were compared to data from Lake Opeongo, Ontario and Long Point Bay, Lake Erie. This revealed that the model can be applied to estimate how habitat changes influence fish density but requires modification before it can be used to predict the spatial distribution of nests and fish within a lake.

Rubenson and published by . This book was released on 2019 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riverine distributions of nonnative smallmouth bass (Micropterous dolomieu) are changing in response to climate change, with smallmouth bass upstream extent increasing as temperatures warm to within its thermal tolerances. Although smallmouth bass continue to shift its distribution into new upstream habitat, little is known about the mechanisms that drive or limit distribution changes, its current distributions in the Columbia River Basin, or the potential impacts expanding smallmouth bass may have on juvenile salmonids, each of which I address in this dissertation. Like most ectotherms, each life history stage (i.e., egg, juvenile, adult) of smallmouth bass has unique thermal optimums and limits that may disproportionately affect successful establishment of new self-sustaining populations. In my first two chapters, I examined the effects of increasingly colder temperatures on spawning patterns, reproductive success, and recruitment across a broad (> 60 km) spatial extent in the North Fork John Day River. In my third chapter, I assessed the inter-annual differences in maximum upstream distribution, seasonal changes in local abundances, and seasonal movement patterns of adult bass to assess the role of adult dispersal in range dynamics. Using these data on reproduction, recruitment, and adult movement patterns, I found key behaviors and physiological constraints that limit or drive range expansion and present management strategies that may be useful to managers tasked with preventing future range expansion of smallmouth bass. In my fourth chapter, I developed a species distribution model of smallmouth bass for the Columbia River Basin using a combination of historical distribution data and environmental DNA (eDNA) distribution data collected at predicted range boundaries. Here, I found that smallmouth bass is widely distributed and predicted to overlap with 3-62% of critical salmonid spawning and rearing habitat. Under a moderate climate change scenario, I found that smallmouth bass is predicted to increase its distribution by over two-thirds, highlighting management challenges throughout the Columbia River Basin. Finally, in my fifth chapter I examine potential competition and predation dynamics in a food web that includes smallmouth bass and juvenile Chinook salmon (Oncorhynchus tshawytscha). Here, I found little evidence for a strong predation or competition threat to juvenile Chinook salmon, suggesting that although smallmouth bass is likely to increase its overlap with native salmonids, its greatest impact to salmonids appears to occur in mainstem habitats. Taken together, the five chapters of this dissertation advance the understanding of the physiology, behavior, distribution, and impact of nonnative smallmouth bass in the Columbia River Basin, which will directly contribute to the management of streams home to myriad threatened and endangered native species.

This book was released on 2005 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research explores the degree and causes of life history variation in the smallmouth bass, Micropterus dolomieu. Smallmouth bass are an interesting study species for exploring life history variation for two main reasons: (i) many populations are in various stages of colonization thereby allowing characterization of life history dynamics as a population adapts to a new environment; (ii) they show paternal care, the presence of which may modify patterns of life history response. Variability is examined over a broad scale of geographically diverse populations, between adjacent populations, and temporally within populations. Results indicate that there is a large degree of variation in somatic growth and maturation among smallmouth bass populations and that climate, food availability, and mortality are important drivers of this variation. A significant amount of the among-population differences represent a combination of plastic responses and genetic adaptation to these three forces. Among populations spread over the present North American range of the species, there is a positive relationship between temperature and early growth but the association weakens in non-native populations. On a local scale, food availability and lack of ontogenetic diet shifting appear to have driven much of the phenotypic divergence in growth and maturation between two populations introduced from a common source a century ago. Finally, the results of an individual-based model show that selective mortality can influence population dynamics, somatic growth, and evolution of maturation in a short time span. However, the addition of survival functions associated with parental care reduces the magnitude of evolutionary response. This study underscores the importance of considering population life history as dynamic and capable of showing rapid plastic and/or genetic responses to both natural and human forces.

This book was released on 2017 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying the biotic and abiotic factors that influenceindividual reproductive fitness under natural conditions is essential for understanding important aspects of a species? evolutionary biology and ecology, population dynamics, and life-history evolution. Using next generation sequencing technology, I developed five microsatellite multiplex reactions suitable for conducting large scale parentage analysis of smallmouth bass, Micropterus dolomieu, and used molecular pedigree reconstructiontechniquesto characterize the genetic mating system and mate selection inadult smallmouth bass nesting in Lake Opeongo, Ontario, Canada. I used multivariate spatial autocorrelation analysis to indirectly infer the occurrence and extent of natal philopatry among spawning adults, to assess the strength and direction of sex-bias in natal dispersal patterns, and to evaluate the degree of nest site fidelity and breeding dispersal of spawning adults. I also evaluatedhow differences in littoral zone water temperature caused by wind-induced seiche events influence the relative reproductive success of spawning adults. Lastly, I provide a synopsis of potential future research aimed at further exploring factorsthatinfluence the reproductive fitness of smallmouth bass in Lake Opeongo. This information will contribute to our understanding of the factors regulating smallmouth bass populations, and provide insight into the factors controlling the variance in individual reproductive success and thus recruitment dynamics in this species.

This book was released on 2018 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Smallmouth Bass Micropterus dolomieu is one of the most socially, economically, and ecologically important species in North America. The Snake River, Idaho, supports a popular Smallmouth Bass sport fishery, but little is known about the population. Additionally, anglers and Idaho Department of Fish and Game staff in the study area have expressed concern about the harvest of Smallmouth Bass associated with spawning congregations in and near the lower reaches of several major tributaries (i.e., Payette and Weiser rivers). This thesis describes the population dynamics, demographics, and movement of Smallmouth Bass in the Snake River, Idaho between Swan Falls Dam and Brownlee Dam. Results of this study indicate the population can be characterized by fast growth, good size structure and body condition, low exploitation, and highly variable movement throughout the system. Under current conditions, management changes (e.g., minimum length limit increase, seasonal fishing restrictions) in the system do not seem warranted. Furthermore, this research provides guidance for managers in the western United States where information on the distribution and ecology of Smallmouth Bass in streams and rivers is limited.

This book was released on 2007 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Toward the southwestern edge of the smallmouth bass (Micropterus dolomieu) natural range, the Boston Mountains Ecoregion of Arkansas contains streams which are prone to drying during the summer due especially to hydrogeologic conditions and high evapotranspiration rates. Associated changes in habitat throughout the summer have the potential to negatively affect smallmouth bass. The objectives of this study were to characterize smallmouth bass summer habitat use and characterize changes in the extent of available habitat (velocity, depth, temperature, and substrate) throughout this potentially critical time. Study streams included the North, Middle, and East Forks of the Illinois Bayou in the Ozark National Forest. Sixty radio-transmitters (20 per stream) were surgically implanted into smallmouth bass during May and fish were tracked until October 2006. Habitat characteristics were measured three times from June-September, except substrate (assessed only once). As summer progressed, most riffle and run habitat dried completely resulting in a series of disconnected, remnant pools. Losses in wetted area of some study sections exceeded 55% of the total stream area. Smallmouth bass, in all streams and months, were consistently found at a median depth of 0.80 m. When boulder habitat was available, it was preferred; however, cobble, gravel, and bedrock substrates were also utilized. In June, smallmouth bass were found in velocities near 0.01 m/s; however, by July they were confined to remnant pools where velocity was below detection levels and water temperature occasionally exceeded 30C.
