Brachyhypopomus Bullocki, a New Species of Electric Knifefish
ISSN 0097-3157 PROCEEDINGS OF THE ACADEMY OF NATURAL SCIENCES OF PHILADELPHIA 158: 183-192 APRIL 2009 Brachyhypopomus bullocki, a new species of electric knifefish (Gymnotiformes: Hypopomidae) from northern South America JOHN P. SULLIVAN Department of Ichthyology, The Academy of Natural Sciences, 1900 Benjamin Franklin Parkway, Philadelphia, PA 19103-1195, USA, Email: [email protected] CARL D. HOPKINS Department of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853-2702, USA, Email: [email protected] ABSTRACT.—We describe the new species Brachyhypopomus bullocki (Gymnotiformes: Hypopomidae) from the río Orinoco basin of Colombia and Venezuela as well as the Takutu River/rio Branco-rio Negro basin of Guyana and Brazil. Among its congeners, B. bullocki most closely resembles Brachyhypopomus brevirostris (Steindachner, 1868) in possessing an elongated caudal filament which may reach up to 45% TL in reproductive males, in having wide, evenly spaced saddles of pigment over the dorsum connecting to lateral bands of pigment along the abdominal flanks, and in having a mesocoracoid bone. This new species is distinguished from B. brevirostris and other members of the genus by a large eye (15.5–19.2% of head length), a short abdomen usually with 12 pre-caudal vertebrae, and poorly ossified third and fourth branchiostegal rays that are enlarged distally, producing a bulbous appearance of the opercular region. The electric organ discharge waveform of B. bullocki is biphasic, 0.9–1.6 milliseconds in duration, and the pulse rate varies from 20–80 Hz. RESUMEN.— Se describe la nueva especie Brachyhypopomus bullocki (Gymnotiformes: Hypopomidae) de la cuenca del río Orinoco de Colombia y Venezuela, como así también de la cuenca del Río Takutu/Rio Branco-Rio Negro de Guyana y Brasil. -
Phylogenetic Relationships of the South American Doradoidea (Ostariophysi: Siluriformes)
Neotropical Ichthyology, 12(3): 451-564, 2014 Copyright © 2014 Sociedade Brasileira de Ictiologia DOI: 10.1590/1982-0224-20120027 Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes) José L. O. Birindelli A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae), as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysus and Liosomadoras, and Pseudotatia and Pseudauchenipterus, respectively, and two large ones with the remaining genera. Within the Doradidae, parsimony analysis recovered Wertheimeria as sister to Kalyptodoras, composing a clade sister to all remaining doradids, which include Franciscodoras and two monophyletic groups: Astrodoradinae (plus Acanthodoras and Agamyxis) and Doradinae (new arrangement). Wertheimerinae, new subfamily, is described for Kalyptodoras and Wertheimeria. Doradinae is corroborated as monophyletic and composed of four groups, one including Centrochir and Platydoras, the other with the large-size species of doradids (except Oxydoras), another with Orinocodoras, Rhinodoras, and Rhynchodoras, and another with Oxydoras plus all the fimbriate-barbel doradids. Based on the results, the species of Opsodoras are included in Hemidoras; and Tenellus, new genus, is described to include Nemadoras trimaculatus, N. -
Analysis of the Diet Between an Invasive and Native Fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduct
Analysis of the diet between an invasive and native fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduction Non-native species are the second greatest threat to global species biodiversity after land development (Vitousek, D'Antonio, Loope, Rejmanek, & Westbrooks, 1997). Due to the magnitude of this threat, it is vital that the impacts of exotic species are understood. Fish biodiversity is especially threatened by the ecological changes caused by non-native species (Gozlan, Britton, Cowx, & Copp, 2010). Having higher species diversity allows more ecological processes to take place, protecting the resources of that system, and making it more resilient to change (Folke, 2006). Adding outside inputs, such as additional non-native species, into an ecosystem can have beneficial or compromising effects depending on the amount and type. Invasive species have been shown to reduce native species richness and diversity of native organisms. Some have argued that the transportation of species from one ecosystem to another is actually beneficial for diversity, and non-native species are not really an environmental “problem”. Introductions of non-native species increase diversity at a local level because in the short term there will be a lag time where both non-native and natives can coexist (Lodge, Stein, Brown, Covich, Bronmark, Garvey and Klosiewski, 1998). Species entering a new ecosystem have to pass through a gauntlet of barriers before they can become established. The usual progression of invasion is: transportation to the new ecosystem, initial establishment, spread to a larger region, and then naturalization into the new community (Marchetti, Light, Moyle, and Viers, 2004). -

Convergent Evolution of Weakly Electric Fishes from Floodplain Habitats in Africa and South America
Environmental Biology of Fishes 49: 175–186, 1997. 1997 Kluwer Academic Publishers. Printed in the Netherlands. Convergent evolution of weakly electric fishes from floodplain habitats in Africa and South America Kirk O. Winemiller & Alphonse Adite Department of Wildlife and Fisheries Sciences, Texas A&M University, College Station, TX 77843, U.S.A. Received 19.7.1995 Accepted 27.5.1996 Key words: diet, electrogenesis, electroreception, foraging, morphology, niche, Venezuela, Zambia Synopsis An assemblage of seven gymnotiform fishes in Venezuela was compared with an assemblage of six mormyri- form fishes in Zambia to test the assumption of convergent evolution in the two groups of very distantly related, weakly electric, noctournal fishes. Both assemblages occur in strongly seasonal floodplain habitats, but the upper Zambezi floodplain in Zambia covers a much larger area. The two assemblages had broad diet overlap but relatively narrow overlap of morphological attributes associated with feeding. The gymnotiform assemblage had greater morphological variation, but mormyriforms had more dietary variation. There was ample evidence of evolutionary convergence based on both morphology and diet, and this was despite the fact that species pairwise morphological similarity and dietary similarity were uncorrelated in this dataset. For the most part, the two groups have diversified in a convergent fashion within the confines of their broader niche as nocturnal invertebrate feeders. Both assemblages contain midwater planktivores, microphagous vegetation- dwellers, macrophagous benthic foragers, and long-snouted benthic probers. The gymnotiform assemblage has one piscivore, a niche not represented in the upper Zambezi mormyriform assemblage, but present in the form of Mormyrops deliciousus in the lower Zambezi and many other regions of Africa. -
