The 3rd annual meeting of the Ohio (River) Valley Unified Malacologists (OVUM), organized by Tim Pearce, took place at the Carnegie Museum of Natural History in Pittsburgh yesterday. There were 14 participants and 11 presentations. Here are the speakers and very brief summaries of what I thought they talked about in the order of presentation.
Charlie Sturm (CMNH): Ongoing attempts to locate the field notes that were associated with the freshwater mollusk collection of Herman P. Wright that was donated to the Carnegie Museum in 1932 and which has since been sitting uncatalogued in a drawer.
Tim Pearce (CMNH): Studies to correlate the weather data with the short-term movements of snails.
Francisco Borrero (Cincinnati Museum of Natural History): taphonomic evidence for turnover in the freshwater mussel community in the Ohio Brush Creek.
Aydin Örstan (CMNH): Results of the survey done to determine the present range of Cepaea nemoralis in Frederick County, MD that was introduced by the late Wayne Grimm in 1969.
Andrew Turner (Clarion University): Elevated pH, caused by nutrient enrichment (increased phosphorus levels), may interfere with the freshwater gastropods' detection of the chemical cues produced by their predators.
Beth Meyer (Western Pennsylvania Conservancy): Mussel, fish and macroinverterbate survey of the French Creek, PA.
Nevin Welte (WPC): Recent PA Fish and Boat Commission activities related to mussels. These included the collection and relocation of a large number of mussels from behind Carter’s Dam prior to its removal.
Emily Cholak (Clarion University): Effect of predation risk induced by fish and crayfish on the population dynamics of their prey, the freshwater gastropod Helisoma trivolvis.
Kip Brady (New Philadelphia High School): Ecological projects involving freshwater gastropods in high school biology classes. Will the students develop a better appreciation of wildlife?
Tim Pearce (CMNH): Laboratory experiments to determine if the slug Philomycus carolinianus likes to aggregate with its conspecifics?
Aaron Stoler (University of Pittsburgh): How the presence of leaves from different species of trees in the water affect the survival of tadpoles and the gastropods Physa acuta and Helisoma trivolvis.
T. rex was there too.
