3 INTRODUCTION The Twenty-second Annual Meeting of the Missouri Herpetological Association was held September 2009 at Missouri State University Bull Shoals Field Station, Taney County, Missouri. This organization is designed to provide herpetologists in Missouri and surrounding states with an opportunity to meet and exchange ideas regarding current efforts in research and other professional activities. High on the list of priorities is to provide students, involved in research at either the graduate or undergraduate level, (1) the chance to interact with senior herpetologists, and (2) an outlet to present, in a semi-formal setting, the results of their labors. This newsletter is the result of a decision made at the inaugural meeting to provide a means of publicly acknowledging papers presented at this and subsequent annual meetings. Further, the newsletter will inform the herpetological community of new distribution records of Missouri s herpetofauna, additions to the bibliography dealing with the state herpetofauna and provide an outlet for the publication of short notes dealing with the natural history of Missouri amphibians and reptiles. ANNOUNCEMENTS 23 rd Annual Meeting of the Missouri Herpetological Association The Twenty-third Annual Meeting of the Missouri Herpetological Association will be held on October 2010 at Reis Biological Station, Crawford County, Missouri. A call for papers and registration materials will be sent electronically in mid-july. For more information please contact Jeff Briggler at: MHA Spring Field Trip The 2010 spring field trip will be held April at Sam A. Baker State Park in northern Wayne County. The fall field trip this year will be held in late September at Montauk State Park in southwest Dent County. Beginning this year the fall field trip will not be held in conjunction with the annual meeting. Information about the field trips will be sent to MHA members and posted on the MHA website in mid March and mid August. The field trips are open to any one with an interest in amphibians and reptiles. MHA on the Net The Association has an official site on the Internet. Point your browser to for copies of current and past publications and to view photos and information from past field trips and meetings. Send ideas, suggestions, comments, and content to the Webmaster (webmaster@moherp.org). Wanted 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. The species described from Missouri type specimens that haven't appeared on past covers are: Eurycea spelaea, Nerodia fasciata confluens, Carphophis vermis.

4 Abstracts of Papers Presented at the 22 nd Annual Meeting of the Missouri Herpetological Association Reis Biological Station September 2009 POPULATION ECOLOGY AND METAPOPULATION DYNAMICS OF TURTLES ON MISSOURI WESTERN STATE UNIVERSITY S CAMPUS Teresa Ausberger 1, Kristen Sheehan 2, Colton Zirkle 3 and Mark S. Mills 1 1 Department of Biology, Missouri Western State University, St. Joseph, MO 64507; 2 Benton High School, St. Joseph, MO 64504; 3 Central High School, St. Joseph, MO We have initiated a proposed long-term study of the population ecology of turtles in nine ponds on the campus of Missouri Western State University. Our goals for the summer of 2009 were as follows: 1) to determine species composition in all nine campus ponds, 2) to permanently mark all individuals in order to initiate studies on population dynamics, growth, and movement of turtles among ponds or nearby water bodies (e.g., Otoe Creek), 3) to relate physical and biological properties of the ponds to turtle species composition and abundance. To date we have marked 42 turtles representing four species: 21 Chelydra serpentina, 13 Chrysemys picta, 7 Trachemys scripta, and 1 Apalone spinifera. The ponds differ in their size, depth, temperature, composition of bottom sediments (e.g. hard clay vs. silt), amount and make-up of vegetation in and surrounding the ponds, and presence and abundance of fishes among other factors. The ponds also vary greatly in their relative impact from this urban environment. For example, Pond 1 receives nearly all of its water from parking lot run-off and Pond 8 is spring fed. We have captured 2 snapping turtles in Pond 1 compared with 9 turtles of three species in Pond 8. We will test to determine if correlations exist between any of these pond attributes and turtle species composition or abundance. INFLUENCE OF PRIOR EXPOSURE TO PREDATOR CUES ON THE OZARK ZIGZAG SALAMANDER, Plethodon angusticlavius. Jenny Parsons, Alicia Mathis and Adam Crane Department of Biology, Missouri State University, Springfield, MO Detection of chemical cues is important for avoidance of predation for many prey animals. Previous experiments have shown that Ozark zigzag salamanders (Plethodon angusticlavius) make behavioral changes when in direct contact with predatory chemical cues. We predicted that prior exposure to a predator cue would also affect the subsequent behavior of these salamanders. We collected chemical cues from ringneck snakes (Diadophis punctatus) which are known predators of these salamanders. During testing salamanders were removed from their home chambers and exposed them to the either the predator cue or to blank water (control treatment). After 5 min of exposure, salamanders were gently rinsed to remove any snake cues and were then returned to their home chambers. Their behaviors were recorded for an additional 5 min. Salamanders that had been previously exposed to snake cues spent significantly more time in escape behavior and performed more chemosensory sampling (nose-tapping) than salamanders in the control treatment. These results suggest that salamanders avoid areas where they have had previous encounters with predators. LANDMARK LEARNING BY THE OZARK ZIGZAG SALAMANDER, Plethodon angusticlavius Adam Crane and Alicia Mathis Department of Biology, Missouri State University, Springfield, MO Although salamanders have been shown to be able to learn some information through classical conditioning, spatial learning has been largely unstudied. We tested whether salamanders could learn to locate foraging areas through navigational landmarks. Training and testing arenas were large square Petri dishes. We trained 10 salamanders (Plethodon angusticlavius) to use landmarks (small rocks) to Missouri Herpetological Association Newsletter (22),

5 locate patches within the arena containing food (blackworms, Lumbriculus variegatus). At the corners of each arena were four plastic dishes, one containing blackworms and the other three empty. A rock was placed in front of the dish containing blackworms, and the location of the food-dish was randomly chosen for each training trial. A control group was also trained to feed on blackworms in the presence of a rock, but the rock was positioned randomly among the four dish locations so that the rock was not a reliable landmark for the worms. Although the length of the training period for individual salamanders varied (22-34 trainings per individual), the mean number of trainings for salamanders in the control and experimental groups was equal (30 training trials). During testing, no blackworms were present to eliminate any visual or chemical cues emanating directly from the prey. Individuals trained with the rock landmarks spent significantly more time in the area of the landmark than did control salamanders. This is the first report of salamanders learning to use landmarks in orientation. MORPHOLOGICAL AND BEHAVIORAL CHANGES IN THE OZARK ZIGZAG SALAMANDER, Plethodon angusticlavius, FOLLOWING INFECTION WITH THE CHYTRID FUNGUS Alicia Mathis and Adam Crane Department of Biology, Missouri State University, Springfield, MO For unrelated studies of salamander behavior, we collected Ozark zigzag salamanders (Plethodon angusticlavius) from sites in both Missouri and Arkansas. Unfortunately, in April 2009 there was an outbreak of disease among these laboratory animals, and over 50 died. Symptoms of disease included morphological (skin sloughing and loss of digits) and behavioral (raising the trunk legs or tail and apparently disoriented walking) effects. Six preserved specimens that had died following presentation of symptoms were sent to a genetic laboratory for testing for the presence of Bd (Batrachochytrium dendrobatidis) or chytrid, and 100% tested positive. Bd is an emerging amphibian disease that appears to be contributing to amphibian declines worldwide. In July 2009 we began treating the salamanders in our laboratory with an anti-fungal drug (intraconazole). These chemical treatments were generally successful in stopping the Bd mortalities. We are uncertain as to how Bd became introduced to the animals in our laboratory. It seems likely that Bd came from either one or both of our collecting sites. Collection of swabs from field sites could reveal important information about the distribution of Bd in the Ozarks. We are not aware of any other studies that have found Bd in a terrestrial amphibian in the Ozarks. DIGESTIVE EFFICIENCY OF THREE MISSOURI SNAKE SPECIES Boryana S. Koseva, Amanda H. DeBrot, Doug R. Elliot, Chris M. Owens, and Chad E. Montgomery Biology Department, Truman State University, Kirksville, MO Optimal foraging theory predicts that a snake will prey upon food items that maximize net energy gain because net energy intake directly affects an organism s fitness, i.e. lifetime reproductive success. Digestive efficiency, the proportion of energy ingested absorbed through the gut wall, is an important component for determining the energy budget of an organism because not all energy ingested is available to the organism to do work. We determined the effect of prey type, prey mass, and snake body mass on the digestive efficiency of the Northern Water Snake (Nerodia sipedon), the Eastern Garter Snake (Thamnophis sirtalis), and the Black Rat Snake (Pantherophis. obsoleta). We used snakes that represented the full range of adult body sizes for the respective species. We used prey types typically encountered in the wild by the respective species. Prey items included tadpoles and fish for N. sipedon and T. sirtalis and quail eggs and mice for P. obsoleta. THE ECOLOGY OF A SNAKE COMMUNITY IN NORTHERN MISSOURI Peter J. Muelleman and Chad E. Montgomery Biology Department, Truman State University, Kirksville, MO We conducted a mark recapture study of the snake community on the property of Premium Standard Farms, Daviess County, near Trenton, Missouri from spring, 2008 to present. Missouri Herpetological Association Newsletter (22),

6 We located snakes opportunistically within the rocky field and forest habitats surrounding the runoff reservoir of the property. For all captured snakes we measured snout-vent length, tail length, and weight. We marked snakes by PIT tagging or by tail clip if less than 20 grams. To date we have captured 150 individuals from seven species, including the threatened Timber Rattlesnake (Crotalus horridus). Additionally in 2008, two adult female timber rattlesnakes that gave birth and three offspring from each litter were radio tracked to determine if neonates follow their mother to overwintering dens. DETERMINANTS OF CONTEST OUTCOME AND THE USE OF THE AGGRESSIVE CALL IN THE GRAY TREEFROG, Hyla versicolor Michael S. Reichert and H. Carl Gerhardt Division of Biological Sciences, University of Missouri, Columbia, MO Anuran amphibians are excellent models for studies of acoustic communication. Most of these studies have focused on the acoustic criteria of advertisement calls used by females to assess potential mates. However, other signals in the vocal repertoires of the same species have received little attention. In particular, many male frogs produce a distinctive aggressive call that is associated with aggressive interactions with other males. Although many species have aggressive calls, relatively few studies have examined their behavioral significance. Most importantly, we do not know what is being signaled by aggressive calls, and whether these signals are related to the outcome of aggressive contests. We have developed a methodology to stage aggressive interactions in the laboratory, and have begun applying it to describe the use of aggressive calls in aggressive interactions in the gray treefrog, Hyla versicolor. Our preliminary results indicate that body mass was an important determinant of the outcome of aggressive calling interactions, but not physical fights. When competitors were approximately equal in mass, the winner tended to be the individual that instigated aggressive calling. Thus, the aggressive call may serve a dual function: as a signal of body mass, and a conventional signal resolving contest outcomes when mass asymmetries are insufficient to resolve the interaction. ALLIGATOR SNAPPING TURTLE CONSERVATION IN OKLAHOMA Day B. Ligon 1, Brian Fillmore 2 and Dan Moore 3 1 Department of Biology, Missouri State University, Springfield, MO 65897; 2 Tishomingo National Fish Hatchery, Tishomingo, OK 73460; 3 Department of Zoology, Oklahoma State University, Stillwater, OK An alligator snapping turtle population survey conducted in Oklahoma in the late 1990s revealed that the species no longer occurred in much of its historical range. The primary cause of such declines is postulated to be once-robust commercial turtle trapping combined with widespread river impoundment. A head-start program was initiated by Tishomingo National Fish Hatchery in response, and the first captivebred hatchlings in the program were produced there in Since then, captive-reared juveniles have been reintroduced in two river systems. Additionally, 240 adult snapping turtles that were confiscated in Arkansas in 2006 have been translocated to the Washita River drainage in southern Oklahoma. Released turtles have been monitored via a combination of radio telemetry and mark-recapture techniques. These efforts have helped characterize habitat use patterns and produced confirmed sources of mortality of both adult and juvenile snapping turtles. Growth rates of captive-hatched juveniles that were released kept pace with growth of turtles maintained in captivity and fed ad libitum. Finally, nesting patterns and successful recruitment of offspring from translocated turtles has been observed. SEASONAL VARIATION IN THE RELATIVE MASS OF THE TESTIS AND SEXUAL SEGMENT OF THE KIDNEY IN THE OPHIDIA Robert D. Aldridge, Benjamin C. Jellen and Dustin S. Siegel Department of Biology, Saint Louis University, St. Louis, MO Two major structures contribute to the ejaculate in squamates, the testis and the kidney. The testis produces sperm and the kidney produces fluids containing carbohydrates and proteins that are released during ejaculation. The Missouri Herpetological Association Newsletter (22),

7 majority of North American male snakes have a reproductive cycle that is best described as postovulatory spermatogenesis in which sperm are produced in the summer months prior to hibernation and the spring mating season. Sperm are stored in the vas deferens during the winter. Because snakes are polygamous, the sperm of different males compete with one another to fertilize the ova. This intrauterine competition might select for those males who release more sperm during ejaculation to increase the chances of his success. However, because sperm are not being produced during the mating season, an increased ejaculate may limit the number of ejaculations a male can make. In this study we examine the relative importance of the testis and kidney mass by estimating the volume of tissue devoted to sperm production and kidney reproductive secretions in several snake taxa. Preliminary analysis suggests that the sexual portion of the kidney, at the time of mating, equals or exceeds the mass of the testis during peak sperm production. We propose that secretions of the sexual segment, in some snakes, create a viscous barrier to reduce the likelihood of sperm of subsequent matings from reaching the oviduct and may increase the ejaculate volume to facilitate the sperm movement in the oviduct. THE SUITABILITY OF ROADSIDE DITCHES AS HABITAT FOR SALAMANDERS. Trisha L. Crabill and Richard A. Seigel Department of Biological Sciences, Towson University, Towson, MD Roadside ditches are prevalent in many areas and inhabited by a variety of wildlife. To better understand their role in supporting wildlife, we compared populations of sirens in roadside ditches to those in natural wetlands at the John F. Kennedy Space Center in Florida. Sirens were sampled from August 2005 August 2006 at two ditch sites and at two swale sites. I used wire-mesh and crayfish traps to capture sirens and anesthetized animals in MS- 222 to record morphological measurements and to mark with PIT tags. To compare survivorship between habitats, 10 sirens from each habitat type were implanted with radio transmitters. There was no difference between habitat types in the mean size of sirens captured, growth rates, Catch per Unit Effort, body condition or survivorship. Considering the use of roadside ditches by a variety of wildlife and their potential to supplement declining, natural wetlands, resource managers should incorporate these habitats into management strategies. ONTOGENETIC CHANGES IN HABITAT USE AND SPATIAL PATTERNS IN THE COTTONMOUTH, Agkistrodon piscivorus Alex Muensch, Brian Greene, Evan Menzel and Adam Crane Department of Biology, Missouri State University, Springfield, MO Home range size and location are among the most important aspects of animal ecology because they are affected by a multitude of factors. Individual differences in resource requirements often explain spatial pattern variation within populations. Understanding variation in snake home range size and movement patterns has been a common objective of numerous radiotelemetry studies which have often revealed proximate influences of resource distribution and behavioral interactions on spatial patterns. Recent studies on a streamassociated cottonmouth population in southwest Missouri have indicated that spatial variation can be explained by a combination of ecological factors. Despite considerable individual variation, there was a significant positive body size influence on home range size. Additional sources of individual variation were attributed to differential responses to habitat-specific resources related to prey distributions and thermoregulatory opportunities. Adult male home ranges were always centered on grassland habitat patches that contained dense populations of cotton rats, the most appropriately-sized rodent prey, while gravid females were typically associated with very small rocky outcroppings that provided optimal thermal regimes for gestation. Juvenile snakes occupied the smallest home ranges of all monitored snakes and remained in close proximity to the stream habitat. The clear resource-driven differences in home range size and location observed in this study suggest that understanding the location and dispersion of key resources and physiological challenges faced by different individuals should help elucidate the ecological causes of spatial patterns in comparative studies across aquatic systems and geographic locations.

Daniel Division of Biological Sciences, University of Missouri, Columbia, MO Edmond and Daniel (2001, Missouri Herpetological Association Newsletter (14): ) provided the most recent compilation of maximum size records for Missouri amphibians and reptiles. During 2009 two turtles that exceeded these size maxima came to my attention. Both records are deposited in the Dean E. Metter Memorial Collection at the University of Missouri-Columbia. On May 12, 2009 Mark Zurbrink collected a large female Pseudemys concinna at the junction of US 54 and Nichols Rd. near the Lake Regional Health Center in Osage Beach in Camden Co. The carapace length of 33.6 cm was larger than the previous record specimen Missouri Herpetological Association Newsletter (22),

11 collected in Taney Co. The specimen was photographed and released (UMC 1787P). A series of Kinosternon flavescens recently transferred to the University of Missouri collection contained a male with a carapace length of 13.2 cm. The specimen (UMC 8603) was collected from the Rose Pond Conservation Area located approximately 5 miles SSE of Wayland in Clark Co. on May 23, ASSOCIATION EVENTS IN 2009 Brian S. Edmond Computer Services, Missouri State University, Springfield MO Introduction For the fourth year, the Missouri Herpetological Association sponsored three official events: the traditional annual meeting and two field trips. A total of 45 individuals attended at least one of these events. Eleven scientific papers were presented during the twenty-second annual meeting and countless conversations, anecdotes, tales, and plans were exchanged among the members attending the various events. More than 410 individual reptiles and amphibians were observed on the two field trips, representing 26 species (4 salamanders, 7 anurans, 6 lizards, 9 snakes, 1 turtle). Individual animals collected or photographed were deposited in the University of Missouri s Dean E. Metter Memorial Collection and will thus be reported as new records where appropriate and used in future updates of R.E. Daniel and B.S. Edmond Atlas of Amphibian and Reptiles of Missouri ( Furthermore, an official field trip report was provided to the Department of Natural Resources, sponsor of the spring field trip at Taum Sauk Mountain State Park. Photos and details for all association events, past and future, can be found on the Events page of the Association s web site ( Spring 2009 Field Trip: Taum Sauk Mountain State Park The spring field trip was held the weekend of 8-10 May 2009 at Taum Sauk Mountain State Park, Iron County, Missouri. The purpose of the trip was a preliminary herpetological survey of select portions of the park. Nine participants caught more than 300 individual reptiles and amphibians, representing a total of 24 species. The majority of collecting activities occurred on Sat 9 May 2009, but some individual animals were caught on the preceding Friday. Most of the weekend was characterized by pleasant evening temperatures and warm daytime conditions. Saturday began cloudy and overcast, but the sun appeared late in the morning and the high temperature for the day approached 80 o F. Habitats searched included woodlands, glades, streams, ponds, rivers, and roads. A thunderstorm producing extensive local wind damage occurred on Fri 8 May 2009 and several trees in the park were uprooted or otherwise permanently damaged. Many local residents in the areas remained without power as the group left the area Saturday night or Sunday morning. Several new localities were documented for Taum Sauk Mountain State Park, including one unverified county record (i.e., previously reported county record that lacks a supporting voucher) (Great Plains Ratsnake (Pantherophis emoryi)) and three new county records: Pickerel Frog (Lithobates palustris), Southern Coal Skink (Plestiodon anthracinus), and Timber Rattlesnake (Crotalus horridus). The complete species list can be seen in Table 1. Several species of anurans were well-represented with calling individuals. The counts below that are designated with an asterisk (*) are minimum estimates of the number of individuals observed for those species. The MHA would like to thank the Missouri Department of Natural Resources for providing permission to use state park property for the field trip. Special appreciation is extended to Tim Turpin for his hospitality and for leading the group throughout the park on Saturday. Annual Meeting: Bull Shoals Field Station The 22 nd Annual Meeting of the Missouri Herpetological Association was held on September 2009 at Bull Shoals Field Station near Kirbyville, Taney County, Missouri. A total of 34 members, representing 9 institutions and agencies, attended this years meeting. Eleven scientific papers were presented during the regular meeting. A short business meeting followed the last regular presentation. Missouri Herpetological Association Newsletter (22),

12 Business meeting discussion topics included the date and location of the 2010 fall meeting. The Association would like to extend a special appreciation to Alicia Mathis and Missouri State University for graciously hosting the meeting and allowing members to stay overnight gratis at the field station. Fall 2009 Field Trip: Coy Bald, Hercules Glades Wilderness Area The fall field trip was held on Sunday 27 September 2009 at Coy Bald, Hercules Glades Wilderness Area, Mark Twain National Forest, Taney County, Missouri. The purpose of the trip was a brief survey of select portions of the area. Twenty participants caught or observed more than 110 individual reptiles and amphibians, representing a total of 14 species. The entire weekend was characterized by cool temperatures, including the morning of the field trip. Habitats searched included glades, wooded hillsides, shady ravines, and a portion of Long Creek. The complete species list can be seen in Table 1. Spring peepers were heard calling in several places and a freshly-hatched southern leopard frog egg mass was found in a roadside puddle.
