OLDFIELD1,2, ABHINAV KAKUTURU1, WILLIAM I. LUTTERSCHMIDT2, O. TOM LORENZ3, ADAM E. COHEN4, AND DEAN A. HENDRICKSON4 ABSTRACT The Rio Grande Cichlid, Herichthys cyanoguttatus, is native to the drainages of the Gulf Coast of northern Mexico and southern Texas and has been introduced at several sites in the US. Previous observations have suggested that non-native populations in Louisiana that are currently recognized as H. cyanoguttatus resemble another species, the Lowland Cichlid, H. carpintis. Traditional morphological and genetic techniques have been insufficient to differentiate these species, but H. carpintis has been reported to differ fromH. cyanoguttatus in color pattern, so we turned to novel electronic photo archives to determine the identity of the species introduced in Louisiana. First, we used the public databases Nonindigenous Aquatic Species Database and Fishes of Texas to infer the historical distributions of these species in the US.

  • Selection, Constraint, and Adaptation in the Visual Genes of Neotropical Cichlid Fishes and Other Vertebrates
    SELECTION, CONSTRAINT, AND ADAPTATION IN THE VISUAL GENES OF NEOTROPICAL CICHLID FISHES AND OTHER VERTEBRATES by Frances Elisabeth Hauser A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Ecology and Evolutionary Biology University of Toronto © Copyright by Frances E. Hauser 2018 SELECTION, CONSTRAINT, AND ADAPTATION IN THE VISUAL GENES OF NEOTROPICAL CICHLID FISHES AND OTHER VERTEBRATES Frances E. Hauser Doctor of Philosophy, 2018 Department of Ecology and Evolutionary Biology University of Toronto 2018 ABSTRACT The visual system serves as a direct interface between an organism and its environment. Studies of the molecular components of the visual transduction cascade, in particular visual pigments, offer an important window into the relationship between genetic variation and organismal fitness. In this thesis, I use molecular evolutionary models as well as protein modeling and experimental characterization to assess the role of variable evolutionary rates on visual protein function. In Chapter 2, I review recent work on the ecological and evolutionary forces giving rise to the impressive variety of adaptations found in visual pigments. In Chapter 3, I use interspecific vertebrate and mammalian datasets of two visual genes (RH1 or rhodopsin, and RPE65, a retinoid isomerase) to assess different methods for estimating evolutionary rate across proteins and the reliability of inferring evolutionary conservation at individual amino acid sites, with a particular emphasis on sites implicated in impaired protein function. ii In Chapters 4, and 5, I narrow my focus to devote particular attention to visual pigments in Neotropical cichlids, a highly diverse clade of fishes distributed across South and Central America.

    Accelerated Evolution and Functional Divergence of the Dim Light Visual Pigment Accompanies Cichlid Colonization of Central America Frances E. Hauser,1 Katriina L. Ilves,2,3 Ryan K.

Associate editor: Emma Teeling Abstract Cichlids encompass one of the most diverse groups of fishes in South and Central America, and show extensive variation in life history, morphology, and colouration. While studies of visual system evolution in cichlids have focussed largely on the African rift lake species flocks, Neotropical cichlids offer a unique opportunity to investigate visual system evolution at broader temporal and geographic scales. South American cichlid colonization of Central America has likely promoted accelerated rates of morphological evolution in Central American lineages as they encountered reduced competition, renewed ecological opportunity, and novel aquatic habitats. To investigate whether such transitions have influenced molecular evolution of vision in Central American cichlids, we sequenced the dim-light rhodopsin gene in 101 Neotropical cichlid species, spanning the diversity of the clade. We find strong evidence for increased rates of evolution in Central American cichlid rhodopsin relative to South American lineages, and identify several sites under positive selection in rhodopsin that likely contribute to adaptation to different photic environments.

  • Morphometric Variation of the Herichthys Bartoni (Bean, 1892) Species Group (Teleostei: Cichlidae): How Many Species Comprise H
    Neotropical Ichthyology, 13(1): 61-76, 2015 Copyright © 2015 Sociedade Brasileira de Ictiologia DOI: 10.1590/1982-0224-20140067 Morphometric variation of the Herichthys bartoni (Bean, 1892) species group (Teleostei: Cichlidae): How many species comprise H. labridens (Pellegrin, 1903)? Omar Mejía1, Fabián Pérez-Miranda1, Yatzil León-Romero1, Eduardo Soto-Galera1 and Efraín de Luna2 Cichlids of the tribe Heroini have long been a source of taxonomical conflict. In particular, the species included in the Herichthys bartoni group have failed to be recovered as monophyletic in different molecular studies. In this paper we use traditional and geometric morphometrics to evaluate morphological variation in the species included in the H. bartoni complex in order to evaluate the number of species it contains. An update of a previously published DNA barcoding study suggests the existence of three genetic clusters that included the six recognized species analyzed in this study, none of them recovered as monophyletic. On the other hand, geometric morphometrics arise as a useful tool to discriminate species due that traditional morphometrics showed a high overlap in the characters analyzed that prevents the proposal of diagnostic characters. Los cíclidos de la tribu Heroini han experimentado un largo conflicto taxonómico. En particular, las especies incluidas en el grupo Herichthys bartoni no han sido recuperadas como monofiléticas en diversos estudios moleculares. En este artículo nosotros usamos morfometría tradicional y geométrica para evaluar la variación morfológica de las especies incluidas en el complejo H. bartoni para evaluar el numero de especies que contiene. Una actualización de un estudio previo de código de barras de ADN sugiere la existencia de tres grupos genéticos que incluyen las seis especies reconocidas analizadas en este estudio, ninguna de las cuales fue recuperada como monofilética.

  • Feeding Ecomorphologies in the Fish Genus Herichthys (Perciformes: Cichlidae) Based on Stomach Content and Lower Pharyngeal Jaw Shape
    Feeding ecomorphologies in the fish genus Herichthys (Perciformes: Cichlidae) based on stomach content and lower pharyngeal jaw shape Fabian Pérez-Miranda1, Omar Mejía1*, Gerardo Zúñiga1, Eduardo Soto-Galera1 & Oldřich Říčan2 1.

Accepted 20-V-2019. Abstract: Speciation is a multifactorial process with factors acting at different scales of space and time. Trophic niche segregation has promoted the diversification of cichlids fishes in lentic (lacustrine) environments, whether this is also the case in lotic (riverine) systems remains unknown. Herichthys is the genus of cichlids with the most boreal distribution in the Americas comprising 12 currently recognized species, most micro-endemic and only two with a wide distribution. In the present work, we analyzed the stomach content and lower pharyngeal jaw morphologies of the species of the genus to evaluate the possible role of feeding ecology in the diversifica- tion of the group. Trophic strategies varied widely, including omnivores, piscivores, invertivores, molluskivores, detritivores, herbivores and algivores. Low values of Pianka’s index of niche overlap were found in the sym- patric micro-endemic species, while in the widely distributed species the indices ranged from low to very high. The analysis of lower pharyngeal jaw morphologies allowed discriminating a shape associated with piscivorous species from other foraging groups.

    PHYLOGENETICS AND DIVERSIFICATION OF SAILFIN AND SHORTFIN MOLLIES (Mollienesia, Poecilia, POECILIIDAE) A Dissertation by MAURA EVELYN PALACIOS MEJIA Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Gary Voelker Co-Chair of Committee Michael Tobler Committee Members, Kevin Conway David Baumgardner Head of Department, Michael Masser May 2017 Major Subject: Wildlife & Fisheries Sciences Copyright 2017 Maura Evelyn Palacios Mejia ABSTRACT Phylogeography aims to understand the formation of species across space and time. Freshwater fishes are studied because they strongly reflect historical and ecological changes in a region. The objective of this dissertation is to identify historic geological events and ecological factors that shaped the evolution of species in the subgenus Mollienesia (Poecilia, Mollienesia, Poeciilidae) within the geologically dynamic regions of Mexico, Central America, and the Caribbean. I investigate the evolutionary relationships in 19 of the 25 species by conducting phylogenetic, species trees with molecular clock estimates, and ancestral area estimates analyses on a multi-locus dataset. The phylogenetic and species trees results support three main groups: Poeciia latipinna, P. sphenops, and P. mexicana species complexes. The molecular clock estimates are inconclusive and ancestral area estimates indicate the diversity originated from the Maya and Chortis blocks. These findings uncover allopatric and ecological speciation events in the three main regions. I also analyze a three- gene dataset of fine scale sampling in Mexico of the P. sphenops and P. mexicana species complexes under phylogenetic and haplotype network. The phylogenetic results show that Mexican species are a result of independent invasions from Middle America with subsequent diversification.
