Austin State University Program Schedule Welcome and Acknowledgements from the Program Chair Welcome to the 123rd meeting of the Texas Academy of Science! We are excited to bring our meeting to the beautiful campus of Stephen F. Austin State University in Nacogdoches, Texas. Please join me in thanking the Stephen F. Austin State University community and the city of Nacogdoches for graciously hosting our event. We would not be able to hold this meeting without the exemplary work of numerous volunteers. Many thanks to Dr. Alyx Frantzen, who has the formidable task of being the local host, a section chair and the current president of the Academy. The Section Chairs and Vice Chairs have done an amazing job of reviewing abstracts and working with our many authors to produce exciting and informative oral presentation and poster sessions. I would like to send a special thanks to the Academy’s Coordinator of Information Technology, Dr. Ricardo Bernal, whose input was needed during virtually every step of this process. His technical knowledge, prompt replies and unfailing good humor were an essential part of planning this meeting! Highlights of this meeting include the symposium discussing the unique ecology of the Trans- Pecos and Tamaulipan Thornscrub ecoregions, the Graduate Student Oral Presentation Competition, the return of the popular Science Jeopardy Competition and the presentations from this year’s Distinguished Texas Scientist and Outstanding Texas Educator. We look forward to the exciting events of this year’s meeting, learning about the current research being conducted through the state and socializing with old friends and new. Shannon K. Hill, President Elect of the Texas Academy of Science 4 Texas Academy of Science 123rd Annual Meeting at Stephen F. Austin State University Program Schedule About the Texas Academy of Science History First founded by teachers as the Academy of Science in Texas in 1880, the organization as we know it now emerged around 1929 and included a physicist, a botanist, a mathematician and two biologists as its founding members. Now, TAS publishes a peer-reviewed journal (The Texas Journal of Science since 1949), conducts an annual meeting that highlights research across 17 sections across the sciences, provides substantial funding opportunities for students (~$25,000 awarded annually) and facilitates expert testimony on policy issues related to STEM or science education. TAS membership approaches 600 individuals, with a large portion of the membership as students. Mission As part of its overall mission, the Texas Academy of Science promotes scientific research in Texas colleges and universities, encourages research as a part of student learning and enhances the professional development of its professional and student members. TAS possesses a complex, intriguing and long- standing educational mission. Strategic Planning The Texas Academy of Science (TAS) Board of Directors approved a vision for a 5-year Strategic Plan: “to increase the visibility and effectiveness of TAS in promoting strong science in Texas.” As part of that initiative, the Academy seeks to reach out to foundations and organizations that support and benefit the Texas science community. We believe that a number of opportunities exist for strategic partnerships that could bolster the impact of organizations that raise the profile of science in Texas. Our ultimate goal will be to make TAS the premier state academy in the United States; however, this cannot be accomplished without funding from both individuals and corporations. It should also be noted that 100% of the contributions given to TAS for student awards goes directly to the award. THE TEXAS ACADEMY OF SCIENCE INCORPORATED IN 1929; AFFILIATED WITH THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE 5 Texas Academy of Science 123rd Annual Meeting at Stephen F.

Abstract The karyotype of Amphisbaena ridleyi, an endemic species of the archipelago of Fernando de Noronha, in State of Pernambuco, Brazil, is described after conventional staining, Ag-NOR impregnation and fluorescence in situ hybrid- ization (FISH) with a telomeric probe. The diploid number is 46, with nine pairs of macrochromosomes (three metacentrics, four subtelocentrics and two acrocentrics) and 14 pairs of microchromosomes. The Ag-NOR is located in the telomeric region of the long arm of metacentric chromosome 2 and FISH revealed signals only in the telomeric region of all chromosomes. Further cytogenetic data on other amphisbaenians as well as a robust phylogenetic hy- pothesis of this clade is needed in order to understand the evolutionary changes on amphisbaenian karyotypes. Key words: Amphisbaena ridleyi, karyotype, Fernando de Noronha, Ag-NOR, FISH with telomeric probes.

  • Why Do Most Tropical Animals Reproduce Seasonally? Testing Hypotheses on an Australian Snake
    Ecology, 87(1), 2006, pp. 133±143 q 2006 by the Ecological Society of America WHY DO MOST TROPICAL ANIMALS REPRODUCE SEASONALLY? TESTING HYPOTHESES ON AN AUSTRALIAN SNAKE G. P. BROWN AND R. SHINE1 Biological Sciences A08, University of Sydney, New South Wales 2006 Australia Abstract. Most species reproduce seasonally, even in the tropics where activity occurs year-round. Squamate reptiles provide ideal model organisms to clarify the ultimate (adap- tive) reasons for the restriction of reproduction to speci®c times of year. Females of almost all temperate-zone reptile species produce their eggs or offspring in the warmest time of the year, thereby synchronizing embryogenesis with high ambient temperatures. However, although tropical reptiles are freed from this thermal constraint, most do not reproduce year-round. Seasonal reproduction in tropical reptiles might be driven by biotic factors (e.g., peak periods of predation on eggs or hatchlings, or food for hatchlings) or abiotic factors (e.g., seasonal availability of suitably moist incubation conditions). Keelback snakes (Tropidonophis mairii, Colubridae) in tropical Australia reproduce from April to November, but with a major peak in May±June. Our ®eld studies falsify hypotheses that invoke biotic factors as explanations for this pattern: the timing of nesting does not minimize predation on eggs, nor maximize food availability or survival rates for hatchlings. Instead, our data implicate abiotic factors: female keelbacks nest most intensely soon after the cessation of monsoonal rains when soils are moist enough to sustain optimal embryogenesis (wetter nests produce larger hatchlings, that are more likely to survive) but are unlikely to become waterlogged (which is lethal to eggs).

  • Maternal Nest-Site Choice and Offspring Fitness in a Tropical Snake (Tropidonophis Mairii, Colubridae)
    Ecology, 85(6), 2004, pp. 1627±1634 q 2004 by the Ecological Society of America MATERNAL NEST-SITE CHOICE AND OFFSPRING FITNESS IN A TROPICAL SNAKE (TROPIDONOPHIS MAIRII, COLUBRIDAE) G. P. BROWN AND R. SHINE1 Biological Sciences A08, University of Sydney, NSW 2006 Australia Abstract. Do reproducing female reptiles adaptively manipulate phenotypic traits of their offspring by selecting appropriate nest sites? Evidence to support this hypothesis is indirect, mostly involving the distinctive characteristics of used (vs. available) nest sites, and the fact that physical conditions during egg incubation can modify hatchling phenotypic traits that plausibly might in¯uence ®tness. Such data fall well short of demonstrating that nesting females actively select from among potential sites based on cues that predict ®tness- determining phenotypic modi®cations of their offspring. We provide such data from ex- perimental studies on a small oviparous snake (the keelback, Tropidonophis mairii) from the wet-dry tropics of Australia. When presented with a choice of alternative nesting sites, egg-laying females selected more moist substrates for egg deposition. Incubation on wetter substrates signi®cantly increased body size at hatching, a trait under strong positive selection in this population (based on mark±recapture studies of free-ranging hatchlings). Remark- ably, the hydric conditions experienced by an egg in the ®rst few hours after it was laid substantially affected phenotypic traits (notably, muscular strength) of the hatchling that emerged from that egg 10 weeks later. Thus, our data provide empirical support for the hypothesis that nesting female reptiles manipulate the phenotypic traits of their offspring through nest-site selection, in ways that enhance offspring ®tness.
