maliziaRichard Malizia, MS 2011

Rich’s thesis is titled “Analyzing niche stability in Late Ordovician articulated brachiopods during the Richmondian Invasion.” His research focused on using GIS techniques to analyze changes in ecological niches of brachiopod species through time in the rocks around Cincinnati, Ohio. This research addressed the relative constancy of a species’ niche in geologic time, which has implications for both evolutionary theory and understanding changes to modern species due to climate change. Rich received a GSA Grant-in-Aid and an OHIO Center for Ecology and Evolutionary Studies Fellowship to support his research. His thesis work was published in Palaeogeography, Palaeoclimatology, Palaeoecology. Following graduation, Rich returned to his beloved home state of Pennsylvania where he is employed in the environmental field at ARCADIS.

OLYMPUS DIGITAL CAMERANicole Dudei, MS 2009

In Nikki’s thesis,”The impact of the Richmondian Invasion on paleobiogeographic distribution of taxa in the Late Ordovician C4 sequence (Richmondian Stage, Cincinnati, Ohio) including a comparison of range reconstruction methods,” she developed a GIS technique to model species ranges using the Spline tool as well as used genetic algorithm techniques to analyze the early stage of the Late Ordovician Richmondian Invasion by modeling the ecological niches of articulate brachiopods in the Oregonia Formation and equivalents in the Cincinnati, Ohio region. Nikki presented the results of her thesis research at at the 2008 Annual GSA meeting and the 2009 NAPC meeting. She earned a grant from the Geological Society of America to support her work, and part of her thesis was published in Palaeogeography, Palaeoclimatology, Palaeoecology. Nikki is employed by ARCADIS in Wisconsin.

Robert Swisher, MS 2009

Rob’s master’s thesis,”Paleobiogeographical and evolutionary analysis of Late Ordovician C5 sequence brachiopod species with special reference to rhynchonellid taxa” examined how paleoenvironmental parameters affect where species lived and the quality of preservation in the Waynesville, Liberty, and Whitewater Formations of the Ohio, Indiana, Kentucky region. He also conducted a phylogenetic analysis of species within the genera Hypsiptycha, Hiscobeccus, and Lepidocyclus. Rob earned funding from the Geological Society of America to fund his research, and presented results at the 2008 Annual GSA meeting and the 2009 NAPC meeting. Rob subsequently completed a PhD with Steve Westrop at the University of Oklahoma and is now a postdoctoral associate at the University of Chicago in Mark Webster’s lab.
