The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish
LETTER doi:10.1038/nature13451 The evolution of the placenta drives a shift in sexual selection in livebearing fish B. J. A. Pollux1,2, R. W. Meredith1,3, M. S. Springer1, T. Garland1 & D. N. Reznick1 The evolution of the placenta from a non-placental ancestor causes a species produce large, ‘costly’ (that is, fully provisioned) eggs5,6, gaining shift of maternal investment from pre- to post-fertilization, creating most reproductive benefits by carefully selecting suitable mates based a venue for parent–offspring conflicts during pregnancy1–4. Theory on phenotype or behaviour2. These females, however, run the risk of mat- predicts that the rise of these conflicts should drive a shift from a ing with genetically inferior (for example, closely related or dishonestly reliance on pre-copulatory female mate choice to polyandry in conjunc- signalling) males, because genetically incompatible males are generally tion with post-zygotic mechanisms of sexual selection2. This hypoth- not discernable at the phenotypic level10. Placental females may reduce esis has not yet been empirically tested. Here we apply comparative these risks by producing tiny, inexpensive eggs and creating large mixed- methods to test a key prediction of this hypothesis, which is that the paternity litters by mating with multiple males. They may then rely on evolution of placentation is associated with reduced pre-copulatory the expression of the paternal genomes to induce differential patterns of female mate choice. We exploit a unique quality of the livebearing fish post-zygotic maternal investment among the embryos and, in extreme family Poeciliidae: placentas have repeatedly evolved or been lost, cases, divert resources from genetically defective (incompatible) to viable creating diversity among closely related lineages in the presence or embryos1–4,6,11. -
Coping with Life on Land: Physiological, Biochemical, and Structural Mechanisms to Enhance Function in Amphibious Fishes
Coping with Life on Land: Physiological, Biochemical, and Structural Mechanisms to Enhance Function in Amphibious Fishes by Andy Joseph Turko A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Andy Joseph Turko, October 2018 ABSTRACT COPING WITH LIFE ON LAND: PHYSIOLOGICAL, BIOCHEMICAL, AND STRUCTURAL MECHANISMS TO ENHANCE FUNCTION IN AMPHIBIOUS FISHES Andy Joseph Turko Advisor: University of Guelph, 2018 Dr. Patricia A. Wright The invasion of land by fishes was one of the most dramatic transitions in the evolutionary history of vertebrates. In this thesis, I investigated how amphibious fishes cope with increased effective gravity and the inability to feed while out of water. In response to increased body weight on land (7 d), the gill skeleton of Kryptolebias marmoratus became stiffer, and I found increased abundance of many proteins typically associated with bone and cartilage growth in mammals. Conversely, there was no change in gill stiffness in the primitive ray-finned fish Polypterus senegalus after one week out of water, but after eight months the arches were significantly shorter and smaller. A similar pattern of gill reduction occurred during the tetrapod invasion of land, and my results suggest that genetic assimilation of gill plasticity could be an underlying mechanism. I also found proliferation of a gill inter-lamellar cell mass in P. senegalus out of water (7 d) that resembled gill remodelling in several other fishes, suggesting this may be an ancestral actinopterygian trait. Next, I tested the function of a calcified sheath that I discovered surrounding the gill filaments of >100 species of killifishes and some other percomorphs. -

Published online at www.vertebrate-zoology.de on May 15, 2009. > Abstract Osteological structures of Callopanchax are fi rst described and illustrated. Twenty-six characters derived from comparisons of osseous structures among some aplocheiloid fi shes provided evidence supporting hypotheses of relationships among three western African genera (Callopanchax, Scriptaphyosemion and Archiaphyosemion), as proposed in recent molecular analysis. The clade comprising Callopanchax, Scriptaphyosemion and Archiaphyosemion is supported by a laterally displaced antero-proximal process of the fourth ceratobranchial. The sister group relationship between Callopanchax and Scriptaphyosemion is supported by a constriction on the posterior portion of the parasphenoid, an anterior expansion of the hyomandibula, a rectangular basihyal cartilage, an anterior pointed process on the fi rst vertebra, and a long ventrally directed hemal prezygapophysis on the preural centrum 2. Monophyly of Callopanchax is supported by a convexity on the dorsal margin of the opercle, a long interarcual cartilage, and long neural prezygapophyses on the anterior caudal vertebrae. > Key words Killifi shes, Callopanchax, Africa, Osteology, Annual fi shes.

27. Aplocheilidae Bleeker, 1860 = 27. Aplocheilidae
27. APLOCHEILIDAE Bleeker, 1860 Jouke R. VAN DER ZEE, Tonnie WOELTJES et Rudolf H. WILDEKAMP Les Aplocheilidae sont aisément identifiables par la position du pore supérieur du canal latéro-sensoriel préoperculaire assez éloigné de l’œil (fig. 26.2B, 27.1) alors qu’il en est très proche chez les Poeciliidae (fig. 26.2A), ainsi que par la position basse des nageoires pectorales (fig. 26.2B). Les Aplocheilidae sont très riches en espèces, particulière- ment en basse Guinée. Ils sont morphologiquement assez homogènes et leur séparation en espèces peut être extrêmement difficile. Cependant, la famille montre une nette propension aux réarrangements caryologiques spécifiques aux clades, ceux-ci étant fréquemment accompagnés d’un patron de coloration spécifique aux mâles. Le patron de coloration des flancs et des nageoires impaires joue probablement un rôle dans la reconnaissance spécifique. C’est pourquoi, les clés de détermination insisteront sur l’importance du patron de coloration mâle comme caractère distinctif. L’identification des femelles et des juvéniles doit en grande partie se baser sur les mâles associés. Remarques : les poissons attribués ici à la famille Aplocheilidae ont une histoire taxonomique complexe. SCHEEL (1968) les a placés dans la sous-famille Rivulinae qui, à cette époque, était un mélange d’espèces africaines et néotropicales. Les Rivulinae étaient alors une sous-famille des Cyprinodontidae dans l’Ordre des Atheriniformes. Sur la base de caractères ostéologiques et cladistiques, PARENTI (1981) a exclu les Cyprinodontidae des Atheriniformes et les a élevés au rang d’ordre (Cyprinodontiformes). Les Rivulinae (sensu SCHEEL, 1968) sont divisés en deux familles, les Rivulidae incluant les genres du Nouveau Monde et les Aplocheilidae pour les genres de l’Ancien Monde. -

E-mail: [email protected] Abstract Aphyosemion teugelsi is described from specimens collected in a small creek in the upper Wamba River basin in the southwest of the Democratic Republic of the Congo not far from the Angolan border. This is ~400 km outside the known distribution area of the genus. It is distinguished from all other members of the genus Aphyosemion by the combination of broad black margins on all fins in males, a robust lower jaw, a more convex back, a large head with large eyes, a more anterior position of the dorsal fin relative to anal fin, and absence of extensions on the upper and lower caudal fin. Key words: Congo basin, Kwango province, killifish, systematics, taxonomy Resumé Aphyosemion teugelsi est décrit à partir de spécimens récoltés dans une petite crique du bassin de la haute Wamba, sud- ouest de la République Démocratique du Congo, non loin de la frontière angolaise. Ceci est de l'ordre de 400km en dehors de la zone de distribution connue pour le genre. -

Part I of the ichthyological type catalogue of the ZSM (Neumann 2006) reviewed the historic “Old Collection”, of which types were apparently lost in the Second World War. Part II refers to type material physically available in ZSM, including historic types saved and re-inventoried. Rebuilding the ichthyological collection after the war, Otto Schindler received with the so-called “Kähsbauer Donations” historic fish specimens from the Naturhistorisches Museum Wien (NMW). Among them are types from the Natterer and Thayer expeditions to Brazil, from the Hase- man expeditions to South America and from Steindachner’s late Brazil expedition in 1903. As far as possible, exchanged specimens were critically reviewed, traced to original lots and compared with NMW acquisition entries for unambiguous identification.
