  Citation × Citation Citation Abstract Copy Title: The effects of pathogens, UV-B radiation, and introduced species on amphibians in the Pacific Northwest Author: Kiesecker, Joseph Michael I examined two amphibian communities to assess factors that may impact amphibian biodiversity. The results suggest that the potential factors which influence the maintenance of amphibian biodiversity are multi-faceted and thus, attempts to understand these factors must reflect these complexities. I investigated factors that influenced the susceptibility of western toad (Bufo boreas), Cascades frog (Rana cascadae), and Pacific treefrog (Hyla regilla) embryos to infection with the fungal pathogen Saprolegnia ferax. I found that there were considerable interspecific differences in susceptibility of anuran embryos to infection with Saprolegnia. Interspecific differences can be attributed to differences in egg-laying behavior and sensitivity to ambient levels of ultraviolet radiation. I studied the effect of Saprolegnia on competitive interactions between larval R. cascadae and H. regilla. The presence of Saprolegnia differentially affected larval recruitment of the two species and mediated competitive interactions. These results suggest that pathogens may have strong effects on species interactions and thus, when present may have strong influences on community composition. I examined population differences in response of native red-legged frogs (R. aurora) to introduced bullfrogs (R. catesbeiana). Syntopic R. aurora tadpoles reduced their activity and increased their refuge-use when presented with the chemical cues of R. catesbeiana, whereas allotopic R. aurora did not. Predation by R. catesbeiana was lower for syntopic R. aurora compared with animals from allotopic populations. Individuals that are unfamiliar with novel, introduced organisms may not possess adaptations that would prevent a negative encounter. In field experiments I demonstrated that introduced R. catesbeiana, and smallmouth bass Micropterus dolomieui, influenced the microhabitat use, growth, and survival of larval and metamorphic R. aurora. These results illustrate the potential complexities of interactions between native and exotic species. These results also stress the importance of understanding the mechanisms of interactions between native and exotic species to allow for the persistence of native biodiversity.

  Citation × Citation Citation Abstract Copy Title: Spatial and temporal effects of atmospheric deposition, climate, and land management on forest nutrient cycling and biodiversity Author: McDonnell, Todd C. Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The critical load (CL) of atmospheric deposition is the level of deposition below which significant harm to ecosystems is not likely to occur. The critical load provides an understanding of the extent to which terrestrial and aquatic systems may be affected by air pollution at present or in the future. This research implements novel methods for generating CL estimates of N and S deposition and evaluates spatial and temporal trends in soil chemistry and plant biodiversity with respect to future climate and land management scenarios. Results are presented in the context of chemical thresholds known to be associated with adverse impacts to terrestrial and aquatic biota of the southern Appalachian Mountains and high elevation Colorado Rocky Mountains.

  Citation × Citation Citation Abstract Copy Title: Design of an automated system for imaging and sorting soil mesofauna Author: Chamblin, Mike A. Identification and population counts of soil mesofauna can be an important tool for soil ecologists to determine the soil biodiversity. Information provided from population counts can give insight to soil ecologists about the effects of human land use, monitoring soil and water health, benefits of soil biodiversity in agriculture, and the impact of global climate change. The process of performing population counts, which includes classifying and sorting specimens, is very time consuming because of the large diversity and quantities of specimens in soil samples. A mechanical system was designed and developed to automate this process. The system features automated imaging, a pair of linear stages for automated positioning, and a six-axis robot with a pipette end effector for sorting. Images acquired with the system will be used by pattern recognition software to classify specimens from a soil sample. The final system was successful in creating high quality images of 19 species of soil mesofauna and sorting them.
