  • 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.

E-mail: [email protected], [email protected] Abstract Two new species of Australoheros Říčan and Kullander are described. Australoheros ykeregua sp. nov. is described from the tributaries of the río Uruguay in Misiones province, Argentina. Australoheros angiru sp. nov. is described from the tributaries of the upper rio Uruguai and middle rio Iguaçu in Brazil. The two new species are not closely related, A. yke- regua is the sister species of A. forquilha Říčan and Kullander, while A. angiru is the sister species of A. minuano Říčan and Kullander. The diversity of the genus Australoheros is reviewed using morphological and molecular phylogenetic analyses. These analyses suggest that the described species diversity of the genus in the coastal drainages of SE Brazil is overestimated and that many described species are best undestood as representing cases of intraspecific variation. The dis- tribution patterns of Australoheros species in the Uruguay and Iguazú river drainages point to historical connections be- tween today isolated river drainages (the lower río Iguazú with the arroyo Urugua–í, and the middle rio Iguaçu with the upper rio Uruguai).

Published online at www.vertebrate-zoology.de on November 21, 2008. > Abstract Apistogramma erythrura sp.n. is described from the drainage of the lower río Mamoré in the province of Beni in Bolivia. It is most similar to Apistogramma trifasciata, but differs from this species by the complete absence of any abdominal markings below the lateral band. It can be distinguished from all the other described Apistogramma species by the following combination of characters: only two postlacrymal infraorbital lateralis canal pores, fi ve dentary lateralis canal pores, a broad lateral band with even borders that widens posteriorly to a height of at least two and a half scales and extends into the caudal fi n without a caudal spot. Adult males usually with a partly or even completely bright red colouration of their rounded caudal fi n, extremely produced anterior dorsal-fi n lappets and prolonged pelvic-fi n fi laments reaching the posterior end of the anal- fi n base. > Kurzfassung Apistogramma erythrura sp. n. wird aus dem Fluss-System des unteren río Mamoré aus der Provinz Beni in Bolivien beschrieben. Die neue Art ist Apistogramma trifasciata am ähnlichsten, unterscheidet sich von jener Spezies jedoch durch das völlige Fehlen dunkler Zeichnungselemente unterhalb des Lateralbandes.
