Python Research (A Collaborative Project with Dr. Chris Carmichael) Sex pheromones have been conveniently extracted from the shed skins of the red-sided garter snake, Thamnophis sirtalis (Mason et al., 1990), and the brown tree snake, Boiga irregularis (Greene & Mason, 1998). At Malone, we are applying the same methodology to the shed skins of five populations of Indonesian water pythons (Liasis mackloti). Our preliminary studies suggest that sex pheromones are present in the python skin extracts as well.
Recent investigations into the pheromone trailing behavior of the five python populations (formerly regarded as a single species) demonstrate unique geographic patterns that support a reclassification of this group into three separate species. We are currently studying the quantitative differences in the pheromone blends produced by these reproductively isolated python populations. Mason, R.T., H. M. Fales, T. H. Jones, L. K. Pannell & D.

Ornithological Survey conducted for Sippo Lake Since September of 2002, a weekly census has been conducted at Sippo Lake in Canton, OH. The identity and numbers of all birds seen during a 1.5 hour walk have been collected. The long-term goals of this project include the establishment of base-line data for monitoring the fluctuation of species populations (particularly wetland species) and the production of a pamphlet familiarizing Sippo Lake visitors with the avifauna likely to be encountered there on a given date.
