The Effect of Endocannabinoids on Carbachol Induced Contractions in the Rat Uterus 2008 REU Animal Behavior Abstract
The Effect of Endocannabinoids on Carbachol Induced Contractions in the Rat Uterus 2008 REU Animal Behavior Abstract Gilda Bobele Kinsey Institute and the Center for the Integrative Study of Animal Behavior Indiana University, Bloomington, IN Interest in endogenous cannabinoids has been generated by the well-document analgesic properties of exogenous cannabinoids, most familiarly Δ9-tetrahydrocannabinol. The endocannabinoid pathway is a complex signaling system involving CB1 and CB2 G- protein coupled receptors, which are activated by lipid ligands. Previous research has delineated the roles of both receptors in analgesia and nociception by using knockout mice and genetic studies in combination with pain model tests, but - due to pain tolerance differences in the strains of rat used and variation in pain models - previous tests on the properties of the CB1 and CB2 receptors have been conflicting. Regardless, regulation of the endocannabinoid pathway has the potential to regulate pain response and treat pain disorders. Part of the established endocannabinoid system involves a calcium-dependent transacylase-catalyzed enzymatic phosphorylation and hydrolysis that produces of N- acylethanolamines. Endocannabinoids such as anandamide have been shown to antagonize the spontaneous contractility of muscarinic smooth muscle ileum tissue, repressing the observed amplitude of contractions in a concentration-dependent fashion. Contractions in uterine and other smooth muscle tissue are stimulated by the parasympathetic nervous system’s release of acetylcholine, and thus an organ bath experiment was used to manipulate the pathway and observe resulting contractions. Tissue harvested from rats determined to be in estrus of a regularly proceeding cycle was dissected into four samples and mounted in buffer solution at 32 degrees Celsius. -
Department of Biology (Pdf)
Department of Biology 26 Summary The Department of Biology at the University of Louisiana at Lafayette took its current form in the late 1980s, with the merger of the Biology and Microbiology Departments. In Spring of 2019, the department has 28 professorial faculty members, 6 emeritus faculty members, and 7 instructors. Almost all professorial faculty members are active in research and serve as graduate faculty. Our graduate programs are also supported by 8 adjunct faculty members; their affiliations include the United States Geological Survey, the National Oceanographic and Atmospheric Administration, and the Smithsonian Institution. In this report, we summarize research accomplishments of our departmental faculty since 2013. The report is focused on our research strengths; however, faculty members have also been awarded considerable honors and funding for educational activities. We also briefly summarize the growth and size of our degree programs. Grant Productivity From 2013 through 2018, the Department of Biology has secured over 16 million dollars of new research funding (the total number of dollars associated with these grants, which are often multi- institutional, is considerably higher). Publications The faculty has a strong record of publication, with 279 papers published in peer-reviewed journals in the last 5 years. An additional 30 papers were published in conference proceedings or other edited volumes. Other Accomplishments Other notable accomplishments between 2013 and 2018 include faculty authorship of five books and edited volumes. Faculty members have served as editors, associate editors, or editorial board members for 21 different journals or as members of 34 society boards or grant review panels. They presented 107 of presentations as keynote addresses or invited seminars. -
Convergent Evolution of Weakly Electric Fishes from Floodplain Habitats in Africa and South America
Environmental Biology of Fishes 49: 175–186, 1997. 1997 Kluwer Academic Publishers. Printed in the Netherlands. Convergent evolution of weakly electric fishes from floodplain habitats in Africa and South America Kirk O. Winemiller & Alphonse Adite Department of Wildlife and Fisheries Sciences, Texas A&M University, College Station, TX 77843, U.S.A. Received 19.7.1995 Accepted 27.5.1996 Key words: diet, electrogenesis, electroreception, foraging, morphology, niche, Venezuela, Zambia Synopsis An assemblage of seven gymnotiform fishes in Venezuela was compared with an assemblage of six mormyri- form fishes in Zambia to test the assumption of convergent evolution in the two groups of very distantly related, weakly electric, noctournal fishes. Both assemblages occur in strongly seasonal floodplain habitats, but the upper Zambezi floodplain in Zambia covers a much larger area. The two assemblages had broad diet overlap but relatively narrow overlap of morphological attributes associated with feeding. The gymnotiform assemblage had greater morphological variation, but mormyriforms had more dietary variation. There was ample evidence of evolutionary convergence based on both morphology and diet, and this was despite the fact that species pairwise morphological similarity and dietary similarity were uncorrelated in this dataset. For the most part, the two groups have diversified in a convergent fashion within the confines of their broader niche as nocturnal invertebrate feeders. Both assemblages contain midwater planktivores, microphagous vegetation- dwellers, macrophagous benthic foragers, and long-snouted benthic probers. The gymnotiform assemblage has one piscivore, a niche not represented in the upper Zambezi mormyriform assemblage, but present in the form of Mormyrops deliciousus in the lower Zambezi and many other regions of Africa. -

Bernt Maxwell J. Bernt , Aaron H. Fronk , Kory M. Evans 2 [email protected] and James S. Albert From a study of morphological and molecular datasets we determine that a species originally described as Sternarchogiton preto does not form a monophyletic group with the other valid species of Sternarchogiton including the type species, S. nattereri. Previously-published phylogenetic analyses indicate that this species is sister to a diverse clade comprised of six described apteronotid genera. We therefore place it into a new genus diagnosed by the presence of three cranial fontanels, first and second infraorbital bones independent (not fused), the absence of an ascending process on the endopterygoid, and dark brown to black pigments over the body surface and fins membranes. We additionally provide Submitted November 13, 2019 a redescription of this enigmatic species with an emphasis on its osteology, and Accepted February 2, 2020 by provide the first documentation of secondary sexual dimorphism in this species.

Triques Departamento de Zoologia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais. Av. Antônio Carlos 6627, Pampulha, 31270- 901, Belo Horizonte, MG, Brasil. E-mail: [email protected] Abstract Cladistic analysis of external morphology and skeletal characters of Apteronotidae (Teleostei: Gymnotyiformes). Cladistic analysis of external morphology and skeletal characters was undertaken for 37 species of Apteronotidae, Neotropical electric fishes. Orthosternarchus + Sternarchorhamphus (included here in Sternarchorhamphinae status novo) are proposed to be the sister taxa to all remaining apteronotids, most of which form a basal polytomy in Apteronotinae. Several apteronotid species are currently incertae sedis but the monophyly of several genera were corroborated. Sternarchorhynchus is proposed to be the sister group of Ubidia magdalensis + Platyurosternarchus macrostomus, together forming the Sternarchorhynchini. Snout elongation was revealed to have occurred in several independent evolutionary lines as the Sternar- chorhynchini, Orthosternarchus and Sternarchorhamphus. Apteronotus is restricted here to A. albifrons + A. jurubidae and postulated to be the sister group to Parapteronotus, which includes P. hasemani + P. macrostomus. “Apteronotus” leptorhynchus is postulated to be the sister group to “Apteronotus” -
