Ictiólogos de la Argentina: Amalia María Miquelarena

This series will include all those people who, by means of their contributions, great and small, played a part in the consolidation of ichthyology in Argentina. The general plan of this work consists of individual factsheets containing a list of works by each author, along with reference bibliography and, whenever possible, personal pictures and additional material. The datasheets will be published primarily in chronological order, although this is subject to change by the availability of materials for successive editions. This work represents another approach for the recovery and revalorization of those who set the foundations of Argentine ichthyology while in diverse historical circumstances. I expect this to be the beginning of a major work that achieves the description of such a significant part of the history of natural sciences in Argentina.

Peces Anuales de la Argentina.

"Peces anuales" son los especies con un corto ciclo de vida, adaptadas a sobrevivir en aguas temporarias.

Lista comentada de los peces continentales de la Argentina.

En 1987 publicamos una lista de los peces de agua dulce de la Argentina restringida a la información básica, por la que entendíamos los autores de géneros y especies con sus fecha, y las citas de los autores de trabajos que resultaban en modificaciones del catálogo de Ringuelet et al. (1967). A pesar de su modesta presentación (o quizá debido a ella), esa lista alcanzó una divulgación mucho más amplia que la esperada y fue evidente que los investigadores, docentes, funcionarios y alumnos, necesitan un esquema accesible del grupo que los alivie de la búsqueda permanente de las modificaciones taxonómicas, muchas de las cuales en los últimos tiempos han dejado de lado el saludable tono conservador del código de nomenclatura. Después de tres quinquenios la lista está bastante gastada y hemos recibido muchos pedidos de una nueva versión. Dos argumentos nos han decidido a rehacerla bastante en contra de nuestra disposición. La conciencia de que se trata de un trabajo de alguna utilidad como referencia y en temas aplicados, y la evidente circunstancia, curiosamente ignorada, de que las listas faunísticas constituyen la evaluación más inmediata y manejable de la biodiversidad. Esta es una observación que ofrecemos a los lectores y que es ciertamente paradójica; que se destinan enormes esfuerzos y gran cantidad de dinero a la organización de grupos de trabajo, simposios y jornadas sobre la diversidad, cuando ésta en general está a la vuelta de la esquina, en el permanente trabajo taxonómico y faunístico de decenas de investigadores que lo realizan habitualmente. A veces ni siquiera es necesario rastrearla en publicaciones dispersas, ya que parece estar en la naturaleza de los taxónomos preparar listas, catálogos y elencos, que habitualmente no son considerados relevantes como resultado de investigación. Queremos dejar en claro que esta lista, si bien está basada en las mejores fuentes accesibles, no es estrictamente un catálogo crítico, en el sentido que se hayan buscado todas las publicaciones originales, se hayan revisado materiales, o se haya llevado a cabo investigación original sobre todos los grupos. Cualquiera familiarizado con los peces, comprenderá que esa tarea no era posible en el nivel requerido por la taxonomía actual. Sin embargo, hemos buscado las publicaciones originales cuando las dudas excedían lo razonable y hemos revisado material original en nuestro trabajo personal con varios grupos. Las distribuciones se dan de una manera muy general, y se basan principalmente en Ringuelet et al. (1967), con el agregado de datos nuevos publicados que recogimos personalmente. En la consideración de las especies válidas, se han seguido los criterios de autores recientes y, cuando carecíamos de referencias particulares, se utilizaron el Catálogo de la Academia de ciencias de California (Esmeyer, 1998) y el Fish Data Base. Según Margalef, una de las funciones de la ciencia es proveer descripciones abreviadas de los fenómenos. Esta lista es una descripción abreviada de la diversidad de los peces continentales de la Argentina. Incluye todas las especies que se sabe que habitan el país, más unas cuantas que es posible qu4e lo hagan. Todos los cambios que han ocurrido desde la lista anterior están indicados con la referencia a los autores correspondientes. En muchos casos, hemos incluido nuestra opinión y en otros comentamos, con algún detalle, cual es el estado del conocimiento. Las disciplinas cambian, progresan y a veces también, retroceden. Rara vez son inmutables. Esta lista tampoco. (Lista PDF tiene 90 paginas; Indice Ordenes y Familias tiene 17 paginas.)

Redescription of Hypoptopoma inexspectata (Holmberg, 1883), with notes on its anatomy (Siluriformes: Loricariidae).

Hypoptopoma inexspectata is diagnosed and redescribed based on the examination of additional material and comparison with its congeners. This poorly known hypoptopomine species is distributed in the Paraguay and Paraná river draínages. Hypoptopoma inexspectata is diagnosable based on the autapomorphy biserial arrangement of anterior snout rostral margin odontodes, laterally extended to limit between second and third infraorbital plates, with dorsally directed dorsad series separated from ventrally directed ventrad series by a narrow odontode-free area, which at the level of first and second infraorbital plates is reduced to a dividing line of the series. The species can be further distinguished by the combination (1) low number of canal-bearing lateral plates (20-22, typically 21), (2) presence of a shield of prepectoral dermal plates, (3) arrangement of abdominal plates in one paired series of 3-5 plates, (4) shorter least interorbital distance 4856% head lengh, (5) larger horizontal eye diameter 17-20% head lengh, and (6) least orbit-nare distance 812% head lengh. Intraspecific variation skull dermal bones, neuracranium and suspensorium bones, dermal plates, adipose fin is reported. (PDF has 20 pages.)

Lista de los peces de agua dulce de la Argentina.

Lista de peces de agua dulce restringida a la información básica: los autores de géneros y especies, la fecha de descripción, y las referencias bibliográficas a aquellos trabajos que fundamentan las modificaciones o agregados realizados. Las especies introducidas se indican con un asterisco, las limítrofes con esta indicación y entre paréntesis cuando se señala su número.

Fishes of the Lagunas Encadenadas (Province of Buenos Aires, Argentina), a wetland of international importance

The Lagunas Encadenadas form a large endorheic wetland. The system comprises a chain of five main lagoons (Alsina, Chochico, Del Monte, Del Venado, and Epecuen). During two recent collection trips, 13 species of fish were caught. From the collected material and available data in the literature the following points can be made: The fish fauna of this wetland comprises 18 species from 11 families and six orders. Four species (Cyprinus carpio, Hoplias malabaricus, Loricariichthys anus and Parapimelodus valenciennis) are new records for these water bodies. Fish species diversity decreases from east to west, ie from the most freshwater lagoon (Alsina, with 15 species) to the most saline (Epecuen, 1 species). A similar diversity pattern has been found in zooplankton species.
