Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: A variety of sublethal physiological effects have been reported for fish exposed to pulp and paper mill effluents. As mill processing technologies improve, mounting evidence demonstrates fewer effects potentially linked to reduction in wood extractives. Repercussions of sublethal effects at higher levels of biological organization are important questions beginning to be explored. The goal of my study was to evaluate whether sublethal effects in mosquitofish can be used reliably to indicate adverse impact of pulp and paper mill effluents. Biomarkers of anal fin morphology and whole body sex steroids were validated, then studied extensively in wild-caught mosquitofish from Florida effluent-receiving streams that varied markedly in effluent composition.

This book was released on 2016 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary consequence of heated effluent on the Western mosquitofish, Gambusia affinis, was studied at Lake Fairfield, in Freestone County, Texas. The Lake Fairfield reservoir receives heated effluent from Luminant's Big Brown Power Station. Heated effluent from the power station is discharged into a 'hot pond' reservoir before it is allowed to return after cooling to the main reservoir, or 'main lake' of Lake Fairfield. Heated effluent elevates the temperature of the hot pond throughout the year and the elevation in water temperature has selected various life history traits in G. affinis that are divergent from the main lake G. affinis population, such as growth rate, clutch size, reproductive allotment, lipid content, and size at maturity. This work builds upon previous research demonstrating evidence for genetic divergence between the two populations of G. affinis residing in the heated and non-heated regions in Lake Fairfield, and takes the logical next step by exploring these same populations for genetic shifts in life history traits that are directly connected to rates of population growth. This was accomplished by examining patterns of phenotypic life history variation (phenotypic assays) in preserved specimens collected monthly over the course of a year, by performing two sets of reciprocal transplant experiments, and a complimentary common garden experiment. The assessment of phenotypic variation between sites revealed that G. affinis in the hot pond exhibit smaller clutch sizes, smaller reproductive allotment, larger lipid stores, and larger male maturation sizes than G. affinis in the main lake. The results of two independent reciprocal transplant experiments as well as a common garden experiment provide evidence for locally adapted differences as mosquitofish fish from the main lake exhibited faster rates of growth than fish from the hot pond and such differences were generally larger when all populations were reared in the main lake. The assessment of environmental parameters between the hot pond and main lake showed that water temperature was consistently higher in the hot pond and that potentially covarying factors, such as dissolved oxygen, conductivity, salinity, and pH, did not differ between the divergent environments. The observed life history differences between the hot pond and main lake are therefore best explained as driven by elevated water temperature due to the release of heated effluent. Given that the Big Brown Power Station commenced operation in 1971 and has been continuously operating since that time, our results substantiate that human driven alteration to thermal regimes can drive significant evolutionary changes within 44 years. This study provides information on the extent to which species can rapidly adapt to increased environmental temperatures in the form of artificial heating and alter the expression of life history traits when isolated in environments that receive heated effluent. The results of this study also represent an important step in the integration of evolutionary biology and conservation science, and offer information to be considered when adopting management plans for conserving aquatic communities.

This book was released on 2020 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human population growth and its associated effects have contributed to the rapid decrease of biodiversity worldwide. Artificial light at night (ALAN) is an anthropogenic pollutant that is increasing with the spread of urbanization and may contribute to biodiversity declines. ALAN alters the migration patterns of birds, communication in frogs, and impacts reproduction, behavior, and physiology of multiple other taxa. The effects of ALAN on freshwater organisms, however, are largely understudied as compared to terrestrial taxa. I investigated how ALAN affects the physiology, behavior, and reproduction of a widespread freshwater fish. Gambusia affinis are small livebearing fish often found in urban streams. I exposed groups of female G. affinis to either a natural light cycle or a constant 24-hour light cycle (ALAN) in the laboratory for 60 days. In another experiment, I exposed females to the same treatments in outdoor mesocosms for 32 days. I found that exposure to ALAN lowered glucose levels in brain tissue and decreased activity, but had no effect on cortisol release rates, reproduction, survival, or growth. This research is strengthened by measuring multiple metrics in response to ALAN and by incorporating both a field and laboratory component which confirm similar results. Ultimately, these results suggest that ALAN has detrimental effects even on a tolerant species and serious efforts should be taken to reduce its propagation.
