Although presumed to have a statewide distribution, this species has yet to be reported from much of the northern plains ecoregions or from the Mississippi Alluvial plain of the bootheel. The first reported observation of this species in Madison County appears among the new herpetological records appearing in this issue. Missouri Herpetological Association Newsletter (22), 2009 1 INTRODUCTION MHA Spring Field Trip The Twenty-second Annual Meeting of the The 2010 spring field trip will be held Missouri Herpetological Association was held April 24-25 at Sam A. Baker State Park in 26-27 September 2009 at Missouri State northern Wayne County. The fall field trip this University Bull Shoals Field Station, Taney year will be held in late September at Montauk County, Missouri. This organization is designed State Park in southwest Dent County. Beginning to provide herpetologists in Missouri and this year the fall field trip will not be held in surrounding states with an opportunity to meet conjunction with the annual meeting. and exchange ideas regarding current efforts in Information about the field trips will be sent to research and other professional activities. High MHA members and posted on the MHA website on the list of priorities is to provide students, in mid March and mid August. The field trips involved in research at either the graduate or are open to any one with an interest in undergraduate level, (1) the chance to interact amphibians and reptiles. with senior herpetologists, and (2) an outlet to present, in a semi-formal setting, the results of MHA on the Net their labors. This newsletter is the result of a decision made at the inaugural meeting to provide a The Association has an official site on means of publicly acknowledging papers the Internet. Point your browser to presented at this and subsequent annual http://www.moherp.org/ for copies of current meetings. Further, the newsletter will inform the and past publications and to view photos and herpetological community of new distribution information from past field trips and meetings. records of Missouri’s herpetofauna, additions to Send ideas, suggestions, comments, and content the bibliography dealing with the state to the Webmaster ([email protected]). herpetofauna and provide an outlet for the publication of short notes dealing with the Wanted natural history of Missouri amphibians and reptiles. We still need artwork for future cover illustrations. Any species native to the state is acceptable; however, species described from Missouri type specimens and state species of conservation concern are particularly desirable. ANNOUNCEMENTS The species described from Missouri type specimens that haven't appeared on past covers 23rd Annual Meeting of the Missouri are: Eurycea spelaea, Nerodia fasciata confluens, Carphophis vermis. Anyone wishing Herpetological Association to contribute drawings for future issues can send submissions to Richard Daniel at: The Twenty-third Annual Meeting of the Missouri Herpetological Association will Division of Biological Sciences be held on 16-17 October 2010 at Reis 114 Lefevre Hall Biological Station, Crawford County, Missouri.

Missouri Herpetological Association Jenny Parsons, Alicia Mathis and Adam Crane Department of Biology, Missouri State Reis Biological Station University, Springfield, MO 65897 26-27 September 2009 Detection of chemical cues is important for avoidance of predation for many prey POPULATION ECOLOGY AND animals. Previous experiments have shown that METAPOPULATION DYNAMICS OF Ozark zigzag salamanders (Plethodon TURTLES ON MISSOURI WESTERN angusticlavius) make behavioral changes when STATE UNIVERSITY’S CAMPUS in direct contact with predatory chemical cues. We predicted that prior exposure to a predator Teresa Ausberger1, Kristen Sheehan2, Colton cue would also affect the subsequent behavior of Zirkle3 and Mark S. Mills1 these salamanders. We collected chemical cues 1Department of Biology, Missouri Western State from ringneck snakes (Diadophis punctatus) University, St. Joseph, MO 64507; 2Benton High which are known predators of these salamanders. School, St. Joseph, MO 64504; 3Central High During testing salamanders were removed from School, St. Joseph, MO 64501 their home chambers and exposed them to the either the predator cue or to blank water (control We have initiated a proposed long-term treatment). After 5 min of exposure, salamanders study of the population ecology of turtles in nine were gently rinsed to remove any snake cues and ponds on the campus of Missouri Western State were then returned to their home chambers.

These water bodies (e.g., Otoe Creek), 3) to relate results suggest that salamanders avoid areas physical and biological properties of the ponds to where they have had previous encounters with turtle species composition and abundance. To predators. date we have marked 42 turtles representing four species: 21 Chelydra serpentina, 13 Chrysemys LANDMARK LEARNING BY THE OZARK picta, 7 Trachemys scripta, and 1 Apalone ZIGZAG SALAMANDER, Plethodon spinifera. The ponds differ in their size, depth, angusticlavius temperature, composition of bottom sediments (e.g. hard clay vs. silt), amount and make-up of Adam Crane and Alicia Mathis vegetation in and surrounding the ponds, and Department of Biology, Missouri State presence and abundance of fishes among other University, Springfield, MO 65897 factors. The ponds also vary greatly in their relative impact from this urban environment.

We have captured 2 snapping turtles in Pond largely unstudied. We tested whether 1 compared with 9 turtles of three species in salamanders could learn to locate foraging
