  • Fuzzy Logic-Based Expert System for Native Fish Habitat Assessment in a Scarcity Information Context
    Ecohydrology of Surface and Groundwater Dependent Systems: Concepts, Methods and Recent Developments 77 (Proc. of JS.1 at the Joint IAHS & IAH Convention, Hyderabad, India, September 2009). IAHS Publ. 328, 2009. Fuzzy logic-based expert system for native fish habitat assessment in a scarcity information context R. I. MEZA & H. X. VARGAS Civil Engineering Department, Water Resources and Environmental Division, University of Chile, Av. Blanco Encalada #2002, 3º piso, Santiago, Chile [email protected] Abstract Expert systems are typically developed to solve unclear application fields or problems. Such is the case for Chilean river ecosystems, and their fish fauna. In Chile, fish fauna studies are led almost exclusively by biologists, but no or little information is available about reproductive season, fertility, reproductive strategies, age, locomotive capacity, migration, trophic dynamic or niche, to name a few. Quantitative studies are required to analyse the impact of exotic over native species and the antropic effect over a population’s decrease. This information is essential to take appropriate conservation measures for each species and aquatic system. On the other hand, the lack of an adequate hydrometric network forces the use of complementary tools that introduce uncertainties, which are expensive and of difficult quantification. Due to the absence of gauged data for the study area, an expert system application methodology was coupled to the hydrological and hydraulic models, GR4J and HEC-RAS, respectively. Fish species information was taken from biological studies performed for the basin of the Bio Bio River where 17 fish species (13 native and 4 exotic, were found); furthermore, 7 species are classified as vulnerable and 7 are endangered.

[email protected] RESUMEN La ictiofauna nativa de los sistemas límnicos de Chile se compone de 11 familias, 17 géneros y alrededor de 44 especies, incluyendo dos lampreas. De éstas, 81% son endémicas de la provincia biogeográfica chilena y 40% se encuentran clasificadas en peligro de extinción. Los grupos más representados corresponden a los órdenes Siluriformes (11 especies), Osmeriformes (9 especies) y Atheriniformes (7 especies). También están representados en Chile los ciclóstomos Petromyzontiformes (2 especies), y los teleósteos Characiformes (4 especies), Cyprinodontiformes (6 especies), Perciformes (4 especies) y Mugilifromes (1). Latitudinalmente, la mayor riqueza de especies ocurre en la zona centro-sur de la provincia Chilena, en tanto que los extremos norte y sur son de baja riqueza específica. Dado su origen, porcentaje de endemismo y retención de caracteres primitivos, este conjunto ictiofaunístico es de alto valor biogeográfico y de conservación. Existen sin embargo importantes vacíos de conocimiento sobre su sistemática, distribución y biología. PALABRAS CLAVES: Peces, sistemas dulceacuícolas, Chile.

The reported species are Trichomycterus therma n. sp. and Trichomycterus tiraquae. The new species differ from all congeners in the possession of thickened transverse skin on the ventral surface of the head. They are further distinguished from all congeners by the following combination of characteristics: presence of spatulate incisiform premaxillary teeth; presence of large and rounded papilla-like structures on trunk of body; continuous segment of the laterosensory canal within the frontal with the presence of a segment between pores 2 and 6; long laterosensory canal with four to six pores; maxilla with a short anterior process that is smaller than the main axis of the bone, and has an anterior orientation; mesethmoid shaft narrower than the width of the lateral cornua; prepelvic length 58 7–61 0% of Á Á standard length (L ); head width 19 1–22 8% of L ; submaxillary barbel length 23 9–37 5% of S Á Á S Á Á head length (LH).

  • Teleostei: Siluriformes) Inferred from Ultraconserved Elements Luz E
    www.nature.com/scientificreports OPEN Phylogenomic analysis of trichomycterid catfshes (Teleostei: Siluriformes) inferred from ultraconserved elements Luz E. Ochoa 1,2*, Aléssio Datovo2, Carlos DoNascimiento 3, Fabio F. Roxo1, Mark H. Sabaj4, Jonathan Chang5, Bruno F. Melo1, Gabriel S. C. Silva1, Fausto Foresti1, Michael Alfaro5 & Claudio Oliveira1 The family Trichomycteridae is one of the most diverse groups of freshwater catfshes in South and Central America with eight subfamilies, 41 genera and more than 300 valid species. Its members are widely distributed throughout South America, reaching Costa Rica in Central America and are recognized by extraordinary anatomical specializations and trophic diversity. In order to assess the phylogenetic relationships of Trichomycteridae, we collected sequence data from ultraconserved elements (UCEs) of the genome from 141 specimens of Trichomycteridae and 12 outgroup species. We used a concatenated matrix to assess the phylogenetic relationships by Bayesian inference (BI) and maximum likelihood (ML) searches and a coalescent analysis of species trees. The results show a highly resolved phylogeny with broad agreement among the three distinct analyses, providing overwhelming support for the monophyletic status of subfamily Trichomycterinae including Ituglanis and Scleronema. Previous relationship hypotheses among subfamilies are strongly corroborated, such as the sister relationship between Copionodontinae and Trichogeninae forming a sister clade to the remaining trichomycterids and the intrafamilial clade TSVSG (Tridentinae-Stegophilinae-Vandelliinae- Sarcoglanidinae-Glanapteryginae). Monophyly of Glanapteryginae and Sarcoglanidinae was not supported and the enigmatic Potamoglanis is placed outside Tridentinae. Unraveling the relationships of major sections of the Tree of Life is one of the most daunting challenges of the evolutionary biology. Massively parallel DNA sequencing (so-called Next-gen sequencing) is a promising tool that is helping to resolve the interrelationships of longstanding problematic taxa1–4.

Jerep1 and Luiz R. Malabarba2 The cheirodontine genus Macropsobrycon is redefined and considered monotypic. The type species, M. uruguayanae, is redescribed based on samples from the entire known geographical distribution of the species. Sexually dimorphic characters of M. uruguayanae are further described and the relationships of the species with the remaining Compsurini are discussed. O gênero Macropsobrycon de Cheirodontinae é redefinido e considerado monotípico. A espécie-tipo, M. uruguayanae, é redescrita com base em amostras de toda a distribuição geográfica conhecida da espécie. Caracteres de dimorfismo sexual secundário de M. uruguayanae são descritos e as relações da espécie com outros Compsurini são discutidas. Key words: Neotropical, Sexual dimorphism, Systematics, Taxonomy. Introduction from Parecbasis by having fainter dentition and incomplete lateral line, from Aphyodite by having the caudal fin naked Historical review. Eigenmann (1915) described Macropsobrycon, and well developed pseudotympanum, and from Leptobrycon containing a single species, M. uruguayanae, in the subfamily by having the anal fin longer. Although consistent, Eigenmann’s Cheirodontinae. In the Eigenmann’s early concept of this description was incomplete in some aspects as the color pattern subfamily (now corresponding to Aphyocharacinae + of the dorsal and anal fins, and neither mentioned the complex Aphyoditeinae + Cheirodontinae + Paragoniatinae + some caudal-fin structures present on mature males. He still affirmed Tetragonopterinae characid genera sensu Mirande, 2010), the that scales were “apparently absent from caudal” causing Cheirodontinae diagnosis was presented in a topic uncertainty about the presence of them on the caudal fin.
