Derryberry This year we have the privilege to host Dr. Elizabeth P. Derryberry of Tulane University as our keynote speaker. Dr. Derryberry’s lab uses a variety of methods and approaches including field and lab behavioral experiments, phylogenetic and phylogeographic analyses, and genomic tools to address the proximate and ultimate factors controlling variation in communication signals and signaling. Dr. Derryberry graduated in 2000 from the Ecology and Evolutionary Biology department at Princeton University, where she completed a senior thesis on the fitness consequences of parasites in natural populations of white-crowned sparrows (Zonotrichia leucophrys). Dr. Derryberry went on to do her doctoral dissertation work on the patterns and mechanisms of song evolution in white- crowned sparrows in the Nowicki lab at Duke University. In 2007, she joined the Museum of Natural Science at Louisiana State University to study lineage diversification in Neotropical ovenbirds and woodcreepers (Aves: Furnariidae). Dr. Derryberry joined the Tulane Department of Ecology and Evolutionary Biology faculty in 2012. According to her website, she is currently working on several collaborative projects that address the proximate and ultimate factors controlling variation in communication signals using a range of techniques drawn from several disciplines. We are grateful that she has agreed to speak at the RAFWE symposium this year and invite you to come hear about her work. You can learn more about her work at http://elizabethderryberry.tulane.edu/derryberrylab/Home.html #RAFWE 3 Brown Bag Lunch Discussion: “Escape from Science Island!” Construction and Engineering Hall: 11:30-12:30pm Participants in Escape from Science Island include: Tiffany Garcia Associate Professor of Wildlife in the Department of Fisheries and Wildlife.

Come find out! Learn techniques from the likes of Second City and Whose Line Is It Anyway and how they can help you think on your feet and reach a wider audience. Location: LINC 307 RAFWE Workshop #2 Getting the job: Preparing to answer the “diversity question” (Led by Dana Sanchez) Many of the Science, Technology, Engineering, Architecture/Design, and Math (STEAM) disciplines have struggled to increase workforce diversity. Even as participation has begun to broaden, retention and success rates among professionals and students of difference are too often low. Therefore many institutions now screen to select new colleagues who have knowledge of and skills to address these disparities in opportunity and achievement. This short workshop will engage participants in a series of discussions and activities to prepare you to answer “the diversity question.” This workshop is only open to graduate students, and has a 30 person cap. Location: Nash 033 #RAFWE 5 Oral Presentations Session 1: Genetics, Energetics, & Physiology Agricultural Production Room (10:00-11:15) 10:00 - Determining the onset of puberty in free-roaming, un-owned cats Ellie Bohrer1*, Michelle Kutzler2 1Department of Zoology, Oregon State University 2Department of Animal and Rangeland Sciences, Oregon State University *[email protected] Even with numerous successful Trap-Neuter-Release programs, free-roaming un- owned (FRU) cat populations continue to grow. FRU cats cause vast ecological destruction to communities every year, and additionally serve as reservoirs for many diseases. Our laboratory is interested in determining if an underlying biological cause exists for the exuberant reproductive success observed in this animal. We have hypothesized that FRU cats are reaching puberty sooner than what has been previously reported in owned domestic cats. The objective of this study was to analyze fertility markers (spermatogenesis in males and folliculogenesis in females) in varying ages of FRU queens and toms to determine the onset of puberty. FRU cats were presented for castration at a local humane society. Tissues were collected after routine castration, and were formalin- fixed. Tissues were then paraffin-embedded, cut in 6 µm sections, and stained with hematoxylin and eosin. All tissues were examined using bright field microscopy by the same observer (EB) blinded to the age group of the individual. Various statistical tests were performed, and p values <0.05 were considered significant. The onset of puberty appears to occur before 4 months of age in FRU cats, which is significantly earlier than what has been previously reported in owned, domestic cats. We suspect that external stressors and an extremely shortened life span are contributing to this capacity for earlier reproduction. This finding is important for population control programs and veterinarians alike, as it suggests that programs need to focus their sterilization efforts on cats under 4 months of age. Future studies on FRU cat colonies in other geographical areas may help to confirm our findings. 10:15 - Diet composition of fish in upper Willamette reservoirs Chelsea Duke1*, Margaret McCormick1, Christina A.

  • The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
    INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

  • Hemlock Woolly Adelgid Predator Survey In
    AN ABSTRACT OF THE THESIS OF Glenn R. Kohler for the degree of Master of Science in Forest Science presented on March 19, 2007. Title: Predators Associated with Hemlock Woolly Adelgid (Hemiptera: Adelgidae) Infested Western Hemlock in the Pacific Northwest. Abstract approved: _____________________________________________________________________ Darrell W. Ross The hemlock woolly adelgid, Adelges tsugae, is causing widespread mortality of eastern hemlock, Tsuga canadensis, in the eastern United States. In the West, A. tsugae causes negligible damage to western hemlock, Tsuga heterophylla. Host tolerance traits and presence of endemic predators may be contributing to the relative tolerance of western hemlock to A. tsugae. Field surveys of the predator community associated with A. tsugae infestations on 116 T. heterophylla at 16 locations in Oregon and Washington were conducted every four to six weeks from March 2005 through November 2006. Predators collected from A. tsugae infested T. heterophylla represent 55 species in 14 families, listed in order of abundance: Derodontidae, Chamaemyiidae, Hemerobiidae, Coccinellidae, Cantharidae, Reduviidae, Miridae, Syrphidae, Chrysopidae, Coniopterygidae, Staphylinidae, Anthocoridae, Nabidae, and Raphidiidae. Laricobius nigrinus (Derodontidae), Leucopis argenticollis, and Leucopis atrifacies (Chamaemyiidae) are the most abundant predators; together comprising 59% of predator specimens recovered. The abundance of derodontid larvae, L. nigrinus adults, chamaemyiid larvae, and L. argenticollis adults was found to be positively correlated to A. tsugae density. The remaining 52 species represent a diverse complex of predators potentially attacking A. tsugae. However, many are known to feed on non-adelgid prey. Predators were most abundant when the two generations of A. tsugae eggs were present. The phenology of immature and adult predators suggests temporal partitioning of prey across all seasons.
