A New Species of Sand-Dwelling Catfish, with a Phylogenetic Diagnosis of Pygidianops Myers (Siluriformes: Trichomycteridae: Glanapteryginae)
Neotropical Ichthyology, 9(3): 493-504, 2011 Copyright © 2011 Sociedade Brasileira de Ictiologia A new species of sand-dwelling catfish, with a phylogenetic diagnosis of Pygidianops Myers (Siluriformes: Trichomycteridae: Glanapteryginae) Mário C. C. de Pinna1 and Alexandre L. Kirovsky2 A new species of sand-dwelling catfish genus Pygidianops, P. amphioxus, is described from the Negro and lower Amazon basins. The new species differs from its three congeners in the elongate eel-like body, the short barbels, and the small caudal fin, continuous with the body, among other traits of internal anatomy. The absence of anal fin further distinguishes P. amphioxus from all other Pygidianops species except P. magoi and the presence of eyes from all except P. cuao. The new Pygidianops seems to be the sister species to P. magoi, the two species sharing a unique mesethmoid with a dorsally-bent tip lacking cornua, and a produced articular process in the palatine for the articulation with the neurocranium. Pygidianops amphioxus is a permanent and highly-specialized inhabitant of psammic environments. Additional characters are proposed as synapomorphies of Pygidianops, including a hypertrophied symphyseal joint and associated ligament in the lower jaw; an elongate, laterally-directed, process on the dorsal surface of the premaxilla; and a rotated lower jaw, where the surface normally facing laterally in other glanapterygines is instead directed ventrally. These and other characters are incorporated into a revised phylogenetic diagnosis of Pygidianops. Uma nova espécie do gênero de bagre arenícola Pygidianops, P. amphioxus, é descrita de diferentes localidades na Amazônia brasileira. A nova espécie difere de seus três congêneres pelo corpo alongado e anguiliforme, pelos barbilhões curtos e pela pequena nadadeira caudal, contínua com o corpo, além de outras características da anatomia interna. -

Molecular Investigations of the Diversity of Freshwater Fishes Across Three Continents
Molecular Investigations of the Diversity of Freshwater Fishes across Three Continents by Malorie M. Hayes A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 8, 2020 Keywords: Enteromius, Barbus, sub-Saharan Africa, phylogenetics, systematics, Pteronotropis, conservation genetics, Trichomycterus, Guyana Copyright 2020 by Malorie M. Hayes Approved by Jonathan W. Armbruster, Chair, Professor and Director Auburn University Museum of Natural History Department of Biological Sciences Jason E. Bond, Professor and Schlinger Chair in Insect Systematics University of California, Davis Scott R. Santos, Professor and Chair of the Department of Biological Sciences at Auburn University John P. Friel, Director of the Alabama Museum of Natural History Abstract Fishes are the most speciose vertebrates, and incredible diversity can be found within different groups of fish. Due to their physiological limitations, fish are confined to waters, and in freshwater fish, this is restricted to lakes, rivers, and streams. With a constrained habitat like a freshwater system, it can be expected that freshwater fish will show varying levels of diversity depending on a suite of characteristics. Within this dissertation, I examine the diversity of three fish groups: the speciose Enteromius of West Africa, the population genetic diversity of Pteronotropis euryzonus in Alabama and Georgia, and the unexpectedly species rich Trichomycterus from the Guyana highlands. I use molecular methods and geometric morphometrics to determine the systematics of the species and uncover the hidden diversity within their respective groups. When it comes to diversity, the small barbs of Africa are vastly understudied and require a taxonomic revision. -
The Relevance of the Cerrado's Water
THE RELEVANCE OF THE CERRADO’S WATER RESOURCES TO THE BRAZILIAN DEVELOPMENT Jorge Enoch Furquim Werneck Lima1; Euzebio Medrado da Silva1; Eduardo Cyrino Oliveira-Filho1; Eder de Souza Martins1; Adriana Reatto1; Vinicius Bof Bufon1 1 Embrapa Cerrados, BR 020, km 18, Planaltina, Federal District, Brazil, 70670-305. E-mail: [email protected]; [email protected]; [email protected]; [email protected]; [email protected]; [email protected] ABSTRACT: The Cerrado (Brazilian savanna) is the second largest Brazilian biome (204 million hectares) and due to its location in the Brazilian Central Plateau it plays an important role in terms of water production and distribution throughout the country. Eight of the twelve Brazilian hydrographic regions receive water from this Biome. It contributes to more than 90% of the discharge of the São Francisco River, 50% of the Paraná River, and 70% of the Tocantins River. Therefore, the Cerrado is a strategic region for the national hydropower sector, being responsible for more than 50% of the Brazilian hydroelectricity production. Furthermore, it has an outstanding relevance in the national agricultural scenery. Despite of the relatively abundance of water in most of the region, water conflicts are beginning to arise in some areas. The objective of this paper is to discuss the economical and ecological relevance of the water resources of the Cerrado. Key-words: Brazilian savanna; water management; water conflicts. INTRODUCTION The Cerrado is the second largest Brazilian biome in extension, with about 204 million hectares, occupying 24% of the national territory approximately. Its largest portion is located within the Brazilian Central Plateau which consists of higher altitude areas in the central part of the country. -
A New Species of Ammoglanis (Siluriformes: Trichomycteridae) from Venezuela

Freshwaters, Vol. 11, No.3, pp. 255-264,6 figs., 1 tab., November 2000 @2000byVerlagDr. Friedrich Pfeil, MiincheD, Germany - ISSN 0936-9902 A new species of Ammoglanis (Siluriformes: Trichomycteridae) from Venezuela Mario c. C. de Pinna* and Kirk O. Winemiller** A new miniaturized species of the trichomycterid genus Ammoglanisis described from the Rio Orinoco basin in Venezuela. It is distinguished from its only congener, A. diaphanus,by: a banded color pattern formed by internal chromatophores; 5 or 6 pectoral-fin rays (7 in A. diaphanus),5/5 principal caudal-fin rays (6/6 in A. diaphanus),ii+6 dorsal-fin rays (iii+6+i in A. diaphanus),30 or 31 vertebrae (33 in A. diaphanus),six or seven branchiostegal rays (five in A. diaphanus),subterminal mouth (inferior in A. diaphanus)and by the lack of premaxillary and dentary teeth. The two speciesalso differ markedly in a number of internal anatomical traits. Synapomorphies are offered to support the monophyly of the two species now included in Ammoglanis,as well as autapomorphies for each of them. Ammoglanispulex is among the smallest known vertebrates, the largest known specimen being 14.9 mm SL. It is a fossorial inhabitant of shallow sandy sections of clear- and light blackwater streams, and probably feeds on interstitial microinvertebrates. Introduction they have often beensuperficially mis-identified ~ as juveniles of other fish.

In Search of the Amazon: Brazil, the United States, and the Nature of A
IN SEARCH OF THE AMAZON AMERICAN ENCOUNTERS/GLOBAL INTERACTIONS A series edited by Gilbert M. Joseph and Emily S. Rosenberg This series aims to stimulate critical perspectives and fresh interpretive frameworks for scholarship on the history of the imposing global pres- ence of the United States. Its primary concerns include the deployment and contestation of power, the construction and deconstruction of cul- tural and political borders, the fluid meanings of intercultural encoun- ters, and the complex interplay between the global and the local. American Encounters seeks to strengthen dialogue and collaboration between histo- rians of U.S. international relations and area studies specialists. The series encourages scholarship based on multiarchival historical research. At the same time, it supports a recognition of the represen- tational character of all stories about the past and promotes critical in- quiry into issues of subjectivity and narrative. In the process, American Encounters strives to understand the context in which meanings related to nations, cultures, and political economy are continually produced, chal- lenged, and reshaped.

Ledeganckstraat 35, B-9000 Gent, Belgium [email protected] 1 21/06/2011 - 10:33:20 Abstract The catfishes (Siluriformes) comprise a particularly diverse teleost clade, from a taxonomic, morphological, biogeographical, ecological and behavioural perspective. The Neotropical Trichomycteridae (the “parasitic” catfishes) are emblematic of this diversity, including fishes with some of the most specialized habits and habitats among teleosts (e.g. hematophagy, lepidophagy, miniaturization, fossorial habitats, altitudinal extremes). Relatively little information is available on general trichomycterid morphology, as most work so far has concentrated on phylogenetically informative characters, with little concern about general descriptive anatomy. In this paper we provide a synthesis of new and previously-available data in order to build a general picture of basal crown group trichomycterid morphology and of its main modifications. We focus on the evolutionary morphology in two relatively distal trichomycterid lineages, i.e. -
