Abstract

Oligotrophic marl lakes have exceptional water clarity and are rare habitats for associated species but are also susceptible to deterioration because of nutrient enrichment. This thesis aimed to determine the current status and cause of eutrophication at the Magheraveely/Kilroosky Marl Loughs SAC (Northern Ireland, UK), investigate mitigation measures, estimate groundwater influx, and assess the population status of co-designated and endangered white-clawed crayfish Austropotamobius pallipes. The surveyed nine lakes failed EU Water Framework Directive nutrient standards. During thermal stratification anoxic hypolimnia resulted in sediment Phosphorus (P) release that maintained the current trophic status. In extrapolations from measurements on sediment cores from Kilroosky Lough, sediment in hypoxia contributed 0.022 mg P L⁻¹ to the whole-lake concentration. Sediment P release decreased by 59% with aeration and by 60% after removing the upper 10 cm sediment. CaNO3 dosing supressed P release at water NO3 concentrations above 5.6 mg L⁻¹ . Groundwater discharge was measured with a RAD7 radon detector customised to process 16 L water samples. A ²²²Rn mass balance estimated annual groundwater contributions between 40% and 160% of lake volume and between 15% and 62% of total water input depending on site. Trapping surveys and mark-recapture surveys mapped crayfish presence and assessed population size. There was substantial abundance in two lakes and low-level presence in two lakes with one first record. Resampling with a Monte Carlo method investigated the relationship between survey effort and variability of catch per unit effort (CPUE). Even high trapping efforts yielded CPUE results with an excess of 20% relative standard deviation. Therefore, an assessment of conservation targets requires surveys with a measure of uncertainty. Lake restoration and survival of crayfish populations need mitigation of surface water P transfers and inhibition of sediment P release e.g., by CaNO3 dosing to stabilise marl lake self-cleaning mechanisms.

17. Indians Off Track: Cody's Wild West and the Melrose Park Train Wreck of 1904

Abstract

“We were rounding a curve,” recalled Luther Standing Bear, Sioux author, interpreter for the Indian members of Buffalo Bill Cody’s Wild West, and casualty of the Melrose Park train wreck of 1904, ”when suddenly I saw a train behind us, coming at lightning speed. Then came a terrific crash. There was no time even to cry out. When I opened my eyes again, the seats were piled on top of us and the steam and smoke from the engine were pouring in on us in great clouds. My legs were pinned down, and I was perfectly helpless . . . . Blood was everywhere.”Buffalo Bill Cody’s Wild West, a depiction of the American frontier experience, traveled and performed throughout the United States and Europe. By 1904, it was a well-established and well-known entertainment attraction in its twenty-first year of operation.Train wrecks were among the greatest dangers faced by the members of traveling shows around the turn of the nineteenth century. One of the most dramatic but unpublicized accidents of Cody’s Wild West happened near Melrose Park, Illinois, on 7 April 1904. According to Luther Standing Bear, the Indians were riding in the last car of the train, which, in effect, segregated them from the other passengers, when another train traveling behind them at ”lightening speed” plowed into the back of the Indians’ car. Standing Bear was one of the more seriously injured, sustaining three bruised and two broken ribs, cuts above both eyes, a severe gash on the back of his head, dislocation of both hips, and a broken left arm, left leg, collar bone, and nose.
