  • Behavioral Evidence of Chemical Communication by Male Caudal Fin Organs of a Glandulocaudine Fish (Teleostei: Characidae)
    1 Ichthyological Exploration of Freshwaters/IEF-1127/pp. 1-11 Published 22 September 2020 LSID: http://zoobank.org/urn:lsid:zoobank.org:pub:483EB8ED-1D49-4584-9030-DE92226A6771 DOI: http://doi.org/10.23788/IEF-1127 Behavioral evidence of chemical communication by male caudal fin organs of a glandulocaudine fish (Teleostei: Characidae) Clayton Kunio Fukakusa* All fishes in the tribe Glandulocaudini have hypertrophied tissue with club cells in the caudal fin (the caudal organ). Because this structure is present only in adult males, it is hypothesized that these cells secrete a reproduction-related pheromone. The hypothesis that the caudal organ releases chemicals that attract females is tested in Mimagoniates inequalis. In a Y-maze and an aquarium, females were attracted to a caudal organ extract and to water that was conditioned with caudal organ-bearing males, respectively, but not to caudal-fin lobe extract or water conditioned with males from which the caudal organs were removed (control stimuli). In tests with male-female pairs, there were no differences in the responses to caudal organ extract and male caudal organ-conditioned water, but the responses to both stimuli differed in relation to the controls. Male-female pairs engaged in fewer courtship events and more agonistic interactions than they did without chemical stimuli and with control stimuli. These results provide evidence for a possible pheromonal system in M. inequalis. The caudal organ is a specialized secretory structure that produces a chemical signal that attracts females and increases the aggressiveness of males.

  • Reproductive Characteristics of Characid Fish Species (Teleostei
    Reproductive characteristics of characid fish species (Teleostei... 469 Reproductive characteristics of characid fish species (Teleostei, Characiformes) and their relationship with body size and phylogeny Marco A. Azevedo Setor de Ictiologia, Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, Rua Dr. Salvador França, 1427, 90690-000 Porto Alegre, RS, Brazil. ([email protected]) ABSTRACT. In this study, I investigated the reproductive biology of fish species from the family Characidae of the order Characiformes. I also investigated the relationship between reproductive biology and body weight and interpreted this relationship in a phylogenetic context. The results of the present study contribute to the understanding of the evolution of the reproductive strategies present in the species of this family. Most larger characid species and other characiforms exhibit a reproductive pattern that is generally characterized by a short seasonal reproductive period that lasts one to three months, between September and April. This is accompanied by total spawning, an extremely high fecundity, and, in many species, a reproductive migration. Many species with lower fecundity exhibit some form of parental care. Although reduction in body size may represent an adaptive advantage, it may also require evolutionary responses to new biological problems that arise. In terms of reproduction, smaller species have a tendency to reduce the number of oocytes that they produce. Many small characids have a reproductive pattern similar to that of larger characiforms. On the other hand they may also exhibit a range of modifications that possibly relate to the decrease in body size and the consequent reduction in fecundity.

C. Castro Probolodus is a genus of tetras distributed along the coastal basins of southeastern Brazil, from Espírito Santo on the north, to São Paulo states. It was proposed by Eigenmann in 1911, to include the single species P. heterostomus. However, examining of material recently collected we identified two new species: P. oyakawai, new species, from the rio Ribeira de Iguape basin, and P. sazimai, new species, from the rio Itapemirim (Espírito Santo), and drainages of the rio Doce basin (Espírito Santo and Minas Gerais states). Therefore, the distribution of P. heterostomus was restricted to the rio Paraíba do Sul basin, southeastern Brazil. The genus Probolodus was redefined based on osteological characters, in particular details of oral dentition. Probolodus heterostomus differs from its congeners by a combination of meristic and osteological characters. An identification key for the species of the genus is presented. The possible evolutionary relationships of Probolodus with other characids, especially some lepidophagous taxa are discussed. Regarding the biogeography of the group, some geological events are hypothesized as responsible for the cladogenetic events among species of the genus. Probolodus é um gênero de lambari distribuído ao longo das bacias costeiras do sudeste brasileiro, do Espírito Santo até São Paulo. Foi proposto originalmente por Eigenmann em 1911, para abrigar a única espécie P.

  • Riverscape Genetics: Insights Into the Drivers of Divergence in Coastal Brazilian Fishes
    Riverscape Genetics: Insights Into the Drivers of Divergence in Coastal Brazilian Fishes by Andréa Tonolli Thomaz A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Ecology and Evolutionary Biology) in The University of Michigan 2017 Doctoral Committee: Professor L. Lacey Knowles, Chair Professor James Diana Associate Professor Timothy Y. James Professor Diarmaid Ó’Foighil Emeritus Professor Gerald Smith Andréa T. Thomaz [email protected] ORCID iD: 0000-0002-9755-2674 © Andréa T. Thomaz 2017 DEDICATION To my mom Ana thank you for teaching me how to fly ii ACKNOWLEDGMENTS This dissertation started to be conceived years before I enter in my Ph.D. Exactly ten years ago I was finishing my undergraduate in Brazil and, with that, came the certitude that I would like to pursue academia and, more precisely, the project presented here. During these ten years many people helped me to overcome the several steps until the end of my Ph.D., and I’m truly thankful for all of them. Firstly, I would like to thank the University of Michigan, the Rackham Graduate School and, more specifically, the Department of Ecology and Evolutionary Biology (EEB) and the Museum of Zoology (UMMZ) for opening their doors and giving me all the necessary support for an international student pursue its research in this institution. Thank you for always believing in my studies and financially supporting them with Block Grants, Rackham Graduate Student Research Grants, Rackham International Student Award, and Rackham Predoctoral Fellowship Program and the Tinkle Award that I was awarded during my Ph.D.

  • Tectonic History and the Biogeography of the Freshwater Fishes from the Coastal Drainages of Eastern Brazil
    Neotrop. Ichthyol., 4(2):225-246, 2006 Copyright © 2006 Sociedade Brasileira de Ictiologia Tectonic history and the biogeography of the freshwater fishes from the coastal drainages of eastern Brazil: an example of faunal evolution associated with a divergent continental margin Alexandre Cunha Ribeiro The eastern Brazilian coastal drainages are of great biogeographical significance, because of their highly endemic fish faunas. Phylogenetic patterns suggest a close biotic relationship between the rivers that flow into the Atlantic and those on the adjacent upland crystalline shield. However, little has been said on the dynamics of the geological processes causally related to the cladogenetic events between these areas. Distributional and phylogenetic patterns suggest a close association with the geological history of the passive continental margin of South America, from the Cretaceous to the present day. In this area megadome uplifts, rifting, vertical movements between rifted blocks and the erosive retreat of the South American eastern continental margin are hypothesized as the main geological forces controlling the distribution of freshwater fishes. The tectonic activity associated with the break-up of Gondwana and separation of South America and Africa formed six megadomes that control most of the current courses of the main crystalline shield river basins. Except for basins located at the edges of such megadomes, these river systems developed long, circuitous routes over the ancient Brazilian crystalline shield before emptying into the recently opened Atlantic Ocean. Initial cladogenetic events between upland crystalline drainages and Atlantic tributaries were probably associated with vicariant processes, and some ancient basal sister-groups of widespread inclusive taxa are found in these coastal hydrographic systems.
