Stressors include both natural ultraviolet radiation (UVR) and a phototoxic polycyclic aromatic hydrocarbon (PAH), fluoranthene (FLU). Due to human activities, both UVR attenuation and PAH levels are increasing, potentially affecting natural processes of the lake. The objective of this study was to understand the individual and population level effects of exposure to different levels of UVR and photo-activated FLU in the two species. Responses to these changes in the native Lahontan redside minnow (Richardsonius egregius) and the non-native warm-water bluegill sunfish (Lepomis macrochirus) were compared in controlled outdoor exposures. Tests were conducted to determine the sensitivity/tolerance of each species, and microscopy techniques were utilized to determine the extent of skin damage, serving as biomarkers of exposure and effect. Natural defenses were also investigated; clarifying in what ways each species may tolerate exposure. This research will help determine the potential for invasive success of the bluegill and similar species in Lake Tahoe and other oligotrophic, montane lakes that are susceptible to habitat alteration, nutrient inputs, and recreational activity. 2010-08-05 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1280515882 http://rave.ohiolink.edu/etdc/view?acc_num=miami1280515882 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
