Mona is a regional manager for the Illinois Emergency Management Agency (IEMA)

70. Michelle Crenshaw MS Biology 2001 Michelle did a thesis on the Paleolimnology of Horseshoe Lake in Alexander County, Illinois. She showed that the lake was very different in pre-settlement times.

His purpose was to study the impact of the University’s heated water effluent on lake stratification and temperature budget.

79. Kevin McKaye. BS Biology 2004. Kevin continued Erin Hammer’s study of carbonaceous particles in Horseshoe Lake sediment. He found that it is possible to measure carbon black using the same equipment used to measure stable isotopes of carbon. His approach could greatly simplify the measurement of elemental carbon in lake sediment.

80. Christina Blackford B.S. Biology 2005. Christina did a senior assignment project on stable isotopes in sediment from Sylvania Wilderness lakes and hollows. She found that δ¹⁵N values decreased in up core in High Lake. Her results indicate that nitrogen from air pollution reaches this lake in a Wilderness area.

Dave used HOBO data loggers to record the temperature of the lake water at 2 hour intervals for 2 years. He showed that the SIUE heating and air-conditioning plant contributes only small amounts of heat to the lake. The title of Dave’s thesis is “Heat Budget of Cougar Lake, Madison County, Illinois”. Click for a pdf of Dave’s thesis. Dave earned a second MS in Environmental Engineering. He is now an inspector for OSHA.

82. Shelly Ottensmeier MS ENSC 2005. Shelly completed a study of stable isotopes of seston in Cougar Lake. She found that δ¹⁵N increased over the summer as a result of sewage inputs from the campus.

88. Brandon James BS BIOL 2006. Brandon did his senior assignment project on the “200 lb squirrel project”. Our collaborator was Dr. Marian Smith from the SIUE Biology department. We planted seeds of various species of Illinois oaks and walnuts around the SIUE campus. Each seed was marked with a numbered flag. Our purpose was to test Bazzaz’s hypothesis that reforestation in Illinois is limited by the ability of large seeded species to disperse to open sites. Brandon examined field and laboratory germination and survival rates using the tetrazolium method. Brandon presented his work at the 2006 Illinois State Academy of Sciences Meeting in Chicago. Click for a copy of his ISAS poster (pdf). Brandon is a Ph.D. student in plant physiology at the University of Illinois Champaign.

89. Beth Martin BS BIOL 2007. Beth did her Ecology Colloquium talk on nitrate in Cougar Lake. Her question was whether denitrification in deep eutrophic lakes removes nitrate from water. She took weekly samples at meter depth intervals from the lake and analysed them for nitrate using a nitrate electrode. Click for handouts of her talk (pdf). Beth moved to Florida and started a dog grooming business.

90. Phil Williams BS MS BIOL. 2009 Phil completed his senior assignment project in the lab. He did a study of stable isotopes in the sediment of Cougar Lake. He found that the recent invasion of the lake by Myriophyllum increased the δ¹³C value of shallow water sediment. Live Myriophyllum showed elevated ¹³C levels because the large beds of macrophytes are extremely carbon-limited. A portion of the carbon fixed by the macrophytes is incorporated into the lake sediment. Phil presented his results at the Illinois State Academy of Sciences meeting in Springfield. Click for a copy of his poster (pdf). Phil completed his MS in Biology his thesis title is “Reconstruction of the History of Cougar Lake, a small eutrophic reservoir in southern Illinois”.

94. Laylonda Maines MS 2009. Laylonda completed her thesis which was a paleolimnological study of lead (Pb) pollution in Horseshoe Lake, Madison County, IL. She found that she could use stable isotopes of lead to track sources to the sediment. Horseshoe Lake has a legacy of lead pollution from a large smelter located in Granite City, IL. The title of Laylonda’s thesis is “Lead contamination of Horseshoe Lake, Madison County, IL by French Colonial Smelters”. Laylonda’s thesis was one source of data for our most recent paper in the Journal of Paleolimnology (Brugam et al. 2012)

She tested hypotheses about environmental change using nitrogen and carbon isotopes. Her thesis title is: Using Ancient and Modern Fishes to Track Environmental Change in the Illinois River. We thank Dr. Terry Martin from the Illinois State Museum for providing archeological specimens for analysis. Kayla is working in quality control and taking her MBA at night and on weekends

105. Stephanie Matthew BS Biol 2013 Stephanie used Kayla’s samples to see if modern fish from the Illinois River have more or less Pb in their bone than bone found in Native American middens.

106. Amanda Deardeuff BS Biol 2014 Amanda sampled zooplankton from ponds at the Watershed Nature Center in Edwardsville. She counted zooplankton and found that the ponds were dominated by rotifers. Her hypothesis was that this is the result of strong fish predation in the ponds. Amanda has moved on to the MS program in Biology at Western Illinois University where she is studying marine mammal conservation.(poster)

107. Jessica Loethen BS Biol 2014 Jessica worked with Amanda, but Jessica analyzed total phosphorus concentrations in the Watershed ponds. She found that the nutrient levels in the ponds were very high (up to 500 micrograms of P per liter). This is not unexpected because the ponds receive high amounts of storm sewer run-off. (poster)
