Osteology, Taxonomy, Phylogeny, and Body Shape Changes of Eocene Catostomid and Problematic Osteology, Taxonomy, Phylogeny, and Body Shape Changes of Eocene Catostomid and Problematic Catostomid Fishes by Juan Liu A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Systematics and Evolution Department of Biological Sciences University of Alberta © Juan Liu, 2016 Abstract Extant catostomid fishes occupy diverse aquatic ecosystems and niches in North America (NA). Less than 3% of catostomid taxonomic richness, or two species, are found outside of NA in Asia. Such adjunct and unbalanced distribution pattern has been established since the late Oligocene, when catostomids disappeared from Asia and became common fishes in NA. Eocene catostomids, representing the oldest fossil records of this family, reached relatively high taxonomic richness in both NA and Asia, and thus are critical to understand evolution of catostomids. This thesis is a study of about 3000 specimens of Eocene catostomids and problematic catostomids. Osteology of 33 extant catostomid species and 11 other otophysans are examined for comparison. Morphological characters are acquired through microscopic examination and CT scans. Cladistic analyses using the parsimony criterion are performed in PAUP 4b10 and TNT 1.5, and explored in MrBayes on XSEDE (3.2.6) using model-based Bayesian inferences through the CIPRES Science Gateway. Analyses of body shape changes and variations of Eocene catostomids are performed using the landmark-based geometric morphometric method. Body shapes of laterally preserved complete fish are captured using surface scanning and digitized with landmarks in TPS utility and TPS dig2, then analysed in MorphoJ 1.06C. First, taxonomy is clarified for Eocene catostomids and problematic catostomids. Of the NA taxa, ii Amyzon gosiutense, a previously hypothesized junior synonym of A. aggregatum, retains its specific status based on a suite of osteological features. “NewGenus” brevipinne is revised from the nominal Amyzon brevipinne and represents the first known shallow bodied, small sized, fluvial-sediment derived, and loach-like catostomid genus. Of the Asian taxa, Jianghanichthys hubeiensis, which was firstly assigned to Osteochilus of Cyprinidae and later Catostomidae, is suggested to be a stem cypriniform based on osteological comparison and phylogenetic analysis. The first fossil family of Cypriniformes, Jianghanichthyidae, is erected to contain the species. Additional problematic catostomids, which were described as Eocene Osteochilus from south China, are assigned to Jianghanichthyidae and combined into two species: Jianghanichthys sanshuiensis and J. linliensis. New species Amyzon kishenehnicum and Jianghanichthys huachongensis are described from NA and Asia, respectively. Second, the systematic position and intrarelationships of Eocene catostomids were largely unresolved before this study, although they are critical to understand the evolution of the family and Cypriniformes. Three sets of phylogenetic analyses based on different character sets are performed. The first set vouches that Jianghanichthys doesn't belong to any known cypriniform family, but is a basal clade. The second set finds that Amyzon is a basal clade of Catostomidae instead of a member in the Ictiobinae. The third suite of analyses is optimized by maximally utilizing Eocene species and creating an osteological character list. These analyses suggest that most Eocene catostomids (except Plesiomyxocyprinus) were stem taxa of Catostomidae, and iii “NewGenus” brevipinne represented the most basal clade. Also, known species of Amyzon are not monophyletic, with Asian A. hunanense and NA A. commune being distinctive basal clades. Another Asian genus Plesiomyxocyprinus is sister to all extant catostomids except ictiobines. Third, Eocene catostomids possess similar general appearances and have highly overlapped meristic and morphometric characters, which caused had taxonomic confusion. Quantitative anatomical comparison in this study (geometric morphometrics) finds significant body shape differences between jianghanichthyids and sampled catostomids, A. aggregatum versus A. gosiutense, and A. aggregatum versus A. kishenehnicum. Regression analysis on Procrustes coordinates and centroid sizes shows that allometry does not significantly affect body shapes differences among well-sampled catostomids and jianghanichthyids. Phylogenetically mapped morphospace indicates evolutionary trajectories and trends of body shape changes are congruent to phylogenetic branches of Eocene catostomids and jianghanichthyids. In sum, all unambiguous oldest cypriniforms are included for discussion (Catostomidae, and Jianghanichthyidae of this study plus Cyprinidae). The only area that all oldest cypriniforms are found is south Asia, which suggests that area is the hotspot of origin and cladogenesis of Cypriniformes. Central Asia, including north China, Mongolia, Kazakhstan, and Fareast Russia, where the last remains of catostomid fossils in Asia recorded cyprinids' dispersal route, is a gateway leading to the dispersal events eastward to NA through Beringia and westward to iv Europe. The mosaic distribution of the Asian taxa across the phylogeny suggests multiple episodes of intercontinental dispersals during the early evolution of catostomids, probably through the freshwater connections of Beringia before the middle Eocene. v Preface This thesis contains published journal articles.

There was no significant difference in genetic diversity between 2009 and 2019P ( > 0.05), but the population structure tended to become stronger. Genetic differentiation (FST) among five populations (LX, BB, YB, SF and JA) collected in 2009 was not significant P( > 0.05). However, some populations collected in 2019 were significantly differentiated (P < 0.05), indicating that the population structure has undergone change.

  • Seasonal and Diel Movements and Habitat Use of Robust Redhorses in the Lower Savannah River. Georgia, and South Carolina
    Transactions of the American FisheriesSociety 135:1145-1155, 2006 [Article] © Copyright by the American Fisheries Society 2006 DO: 10.1577/705-230.1 Seasonal and Diel Movements and Habitat Use of Robust Redhorses in the Lower Savannah River, Georgia and South Carolina TIMOTHY B. GRABOWSKI*I Department of Biological Sciences, Clemson University, Clemson, South Carolina,29634-0326, USA J. JEFFERY ISELY U.S. Geological Survey, South Carolina Cooperative Fish and Wildlife Research Unit, Clemson University, Clemson, South Carolina, 29634-0372, USA Abstract.-The robust redhorse Moxostonta robustum is a large riverine catostomid whose distribution is restricted to three Atlantic Slope drainages. Once presumed extinct, this species was rediscovered in 1991. Despite being the focus of conservation and recovery efforts, the robust redhorse's movements and habitat use are virtually unknown. We surgically implanted pulse-coded radio transmitters into 17 wild adults (460-690 mm total length) below the downstream-most dam on the Savannah River and into 2 fish above this dam. Individuals were located every 2 weeks from June 2002 to September 2003 and monthly thereafter to May 2005. Additionally, we located 5-10 individuals every 2 h over a 48-h period during each season. Study fish moved at least 24.7 ± 8.4 river kilometers (rkm; mean ± SE) per season. This movement was generally downstream except during spring. Some individuals moved downstream by as much as 195 rkm from their release sites. Seasonal migrations were correlated to seasonal changes in water temperature. Robust redhorses initiated spring upstream migrations when water temperature reached approximately 12'C. Our diel tracking suggests that robust redhorses occupy small reaches of river (- 1.0 rkm) and are mainly active diumally.

  • (Nematoda: Thelazioidea) in the Blue Sucker, Cycleptus Elongatus (Lesueur, 1817), from Illinois
    Transactions of the Illinois State Academy of Science received 12/10/01 (2002), Volume 95, #2, pp. 107 - 109 accepted 2/22/02 First Record of Rhabdochona cascadilla Wigdor, 1918 (Nematoda: Thelazioidea) in the Blue Sucker, Cycleptus elongatus (Lesueur, 1817), from Illinois William G. Dyer and William J. Poly Department of Zoology Southern Illinois University Carbondale, Illinois 62901-6501 ABSTRACT Rhabdochona cascadilla was detected in the intestine of Cycleptus elongatus from the Mississippi River in Randolph County, Illinois. This constitutes the first record of this rhabdochonid nematode in the blue sucker and the only internal helminth for this host. INTRODUCTION Nematodes of the genus Rhabdochona Railliet, 1916 (Thelazioidea, Rhabdochonidae) are cosmopolitan in distribution as intestinal parasites of freshwater fishes (Moravec and Coy Otero, 1987; Moravec, 1994). Approximately 96 nominal species have been recognized of which 19 have been reported from North and South America (see Sanchez-Alvarez et al., 1998). Of rhabdochonid nematodes reported from North America, Rhabdochona cascadilla Wigdor, 1918 has been recorded in 13 families, 30 genera, and 53 species of freshwater fishes across Canada and the United States (Hoffman, 1999). Identification of Rhabdochona species is difficult as many of them have been inadequately or erroneously described, and as pointed out by Sanchez-Alvarez et al. (1998), a detailed taxonomic revision of all putative species in this group warrants initiation. MATERIALS AND METHODS A single adult female blue sucker (557 mm standard length) was collected incidentally by electrofishing on 24 October 1996 from the Mississippi River just below the mouth of the Kaskaskia River, Randolph County, Illinois and was transported alive to the laboratory.

  • Barbatula Leoparda (Actinopterygii, Nemacheilidae), a New Endemic Species of Stone Loach of French Catalonia
    Scientific paper Barbatula leoparda (Actinopterygii, Nemacheilidae), a new endemic species of stone loach of French Catalonia by Camille GAULIARD (1), Agnès DETTAI (2), Henri PERSAT (1, 3), Philippe KEITH (1) & Gaël P.J. DENYS* (1, 4) Abstract. – This study described a new stone loach species in France, Barbatula leoparda, which is endemic to French Catalonia (Têt and Tech river drainages). Seven specimens were compared to 49 specimens of B. bar- batula (Linnaeus, 1758) and 71 specimens of B. quignardi (Băcescu-Meşter, 1967). This new species is char- acterized by the presence of blotches on the belly and the jugular area in individuals longer than 47 mm SL and by a greater interorbital distance (35.5 to 41.8% of the head length). We brought moreover the sequence of two mitochondrial markers (COI and 12S, respectively 652 and 950 bp) of the holotype, which are well distinct from all other species, for molecular identifications. This discovery is important for conservation.

  • Four New Records of Fish Species (Cypriniformes: Nemacheilidae
    Zoological Research 35 (1): 51−58 DOI:10.11813/j.issn.0254-5853.2014.1.051 Four new records of fish species (Cypriniformes: Nemacheilidae, Balitoridae; Characiformes: Prochilodontidae) and corrections of two misidentified fish species (Tetraodontiformes: Tetraodontidae; Beloniformes: Belonidae) in Yunnan, China Marco Endruweit* Qingshan Road 601, Qingdao, China Abstract: In this study, six fish species of five families are reported for the first time from Yunnan Province, China.
