Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus. -

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. -

Ciencias Ecológicas, Facultad de Ciencias, Universidad de Chile, Santiago, Chile. [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.

Además, analizamos los posibles orígenes de esta ictiofauna, postulando que parte de la cuenca del río Valdivia ha funcionado como un sumidero, principalmente su parte alta, con aportes de fuentes tanto costero-Pacífi cas como del Este de Los Andes. Concluimos que el río San Pedro es de particular valor ictiofaunístico por su alta riqueza específi ca, endemismos y características biogeográfi cas. PALABRAS CLAVE: Fauna íctica, Río San Pedro, Endemismos, Conservación, Chile. ABSTRACT Based on three consecutive years of sampling and bibliographic revision, the composition, singularity and conservation status of the San Pedro River ichthyofauna is described. In addition, the potential origin of this Valdivia River ichthyofauna was analyzed and this basin is proposed to have worked like a sink, mainly the higher zone, having been colonized both from Coastal-Pacifi c as from Eastern Andes sources. It is concluded that this river has a particular conservation value due to its high species richness, endemism and biogeographic characteristics. -

RENNER 2 2 Systematic Botany and Mycology, University of Munich, 80638 Munich, Germany; and 3 Departamento de Botánica, Facultad de Ciencias Naturales y Oceanográfi cas, Universidad de Concepción, Casilla 160-C, Concepción, Chile • Premise of the study: Understanding the fl exibility of monocot genomes requires a phylogenetic framework, which so far is available for few of the ca. 2800 genera. Here we use a molecular tree for the South American genus Alstroemeria to place karyological information, including fl uorescent in situ hybridization (FISH) signals, in an explicit evolutionary context. • Methods: From a phylogeny based on plastid, nuclear, and mitochondrial sequences for most species of Alstroemeria , we se- lected early-branching (Chilean) and derived (Brazilian) species for which we obtained 18S-25S and 5S rDNA FISH signals; we also analyzed chromosome numbers, 1C-values, and telomere FISH signals (in two species). • Key results: Chromosome counts for Alstroemeria cf. rupestris and A. pulchella confi rm 2 n = 16 as typical of the genus, which now has chromosomes counted for 29 of its 78 species. The rDNA sites are polymorphic both among and within species, and interstitial telomeric sites in Alstroemeria cf. rupestris suggest chromosome fusion. • Conclusions: In spite of a constant chromosome number, closely related species of Alstroemeria differ drastically in their rDNA, indicating rapid increase, decrease, or translocations of these genes. -

(Nematoda) from Paralichthys Isosceles Jordan, 1890 (Pisces: Teleostei) of the Neotropical Region, State of Rio De Janeiro, Brazil
186 Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 107(2): 186-193, March 2012 Genetic and morphological characterisation of a new species of the genus Hysterothylacium (Nematoda) from Paralichthys isosceles Jordan, 1890 (Pisces: Teleostei) of the Neotropical Region, state of Rio de Janeiro, Brazil Marcelo Knoff 1, Nilza Nunes Felizardo1, Alena Mayo Iñiguez2/+, Arnaldo Maldonado Jr3, Eduardo José L Torres4, Roberto Magalhães Pinto1, Delir Corrêa Gomes1 1Laboratório de Helmintos Parasitos de Vertebrados 2Laboratório de Genética Molecular de Microorganismos 3Laboratório de Mamíferos Silvestres Reservatórios, Instituto Oswaldo Cruz-Fiocruz, Av. Brasil 4365, 21045-900 Rio de Janeiro, RJ, Brasil 4Laboratório de Biologia de Helmintos Otto Wucherer, Instituto de Biofísica Carlos Chagas Filho, Universidade Federal do Rio de Janeiro, Rio de Janeiro, RJ, Brasil Taking into account the difficulties of taxonomic identification of larval anisakid nematodes based on mor- phological characters, genetic analyses were performed, together with those usually applied, in order to identify anisakid larvae found in the flounder Paralichthys isosceles from the littoral of the state of Rio de Janeiro, Brazil. The analysis of 1,820 larvae revealed a new species, similar to Hysterothylacium MD, Hysterothylacium 2, Hys- terothylacium KB and Hysterothylacium sp regarding the absence of the larval tooth, an excretory pore situated below the nerve ring level, and slender lateral alae. Moreover, the new species differs from Hysterothylacium for- talezae and Hysterothylacium reliquens with regard to the number and size of spines present on the tail end and from Hysterothylacium patagonicus by the absence of interlabia. The maximum parsimony and neighbour joining tree topologies based on the 18S ribosomal DNA gene, complete internal transcribed spacer region and cytochrome oxidase 2 (COII) gene demonstrated that the Brazilian larvae belong to Raphidascarididae and represent a unique genetic entity, confirmed as a new Hysterothylacium species. -

Presence of the Red Jollytail, Brachygalaxias Bullocki (Regan
Correa-Araneda et al. Revista Chilena de Historia Natural 2014, 87:20 http://www.revchilhistnat.com/content/87/1/20 SHORT REPORT Open Access Presence of the red jollytail, Brachygalaxias bullocki (Regan, 1908) (Galaxiformes: Galaxiidae), in freshwater forested wetlands from Chile Francisco Correa-Araneda1,2,3*, Patricio De Los Ríos2,3 and Evelyn Habit4 Abstract Background: Brachygalaxias bullocki (Regan, 1908) is a small-sized freshwater fish species (41 to 46 mm) and endemic to Chile. Its biology has still various knowledge gaps, and its distribution range has been reduced in the last decade due to human intervention. Findings: In this article, for the first time, its presence in forested wetlands of Chile (38°52′ to 39°02′ S) is documented. The presence of this species in these ecosystems is restricted to wetlands with permanent water regime and depths ranging from 15.7 to 83.5 cm. Conclusions: The physicochemical habitat conditions show important seasonal variations, suggesting that B. bullocki is resistant to a wide range of temperatures, as well as different levels of dissolved oxygen and conductivity. Keywords: Brachygalaxias bullocki; Fish fauna; Forested wetlands; Conservation Findings Consequently, B. bullocki changes in the past 26 years from Brachygalaxias bullocki (Regan, 1908) is an endemic, small- a vulnerable status of conservation (Glade 1988; Campos sized (41 to 46 mm) fish species (Stokell 1954; Cifuentes et al. 1998) to almost endanger (MMA 2014). Our goal is et al. 2012). It is endemic to Chile and still several know- to document, for the first time, the presence of this species ledge gaps about its biology exist (Habit and Victoriano in forested wetlands of Chile, providing more evidence on 2012).
