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. -

Its vast market is supplied from the wild population causing a significant environmental impact. In this study, we assess the effect of photoperiod on ovarian maturation in order to evaluate its potential as a tool to manipulate reproduction under artificial conditions. Four treatments in triplicate (light: dark, L: D) were tested: 24L: 0D, 12L: 12D, 0L: 24D and a progressive photoperiod corresponding to the daily photoperiod increments in wild during winter-spring transition, accelerated three times. -

This study comprises a critical review of relevant literature on the fish fauna, genocentres, means of dispersal, barriers, ecological groups, coactions, and ecological causality of distribution, including an analysis of allotopic species in the lame lake or pond, the application of indexes of diversity of severa¡ biotopes and comments on historical factors. Its wide scope allows to clarify several aspects of South American Ichthyogeography. The location of Argentina ichthyological fauna according to the above mentioned distributional scheme as well as its relation with the most important hydrography systems are also provided, followed by additional information on its distribution in the Argentine Republic, including an analysis through the application of Simpson's similitude test in several localities.

Reproductive Characteristics of Characid Fish Species (Teleostei
Reproductive characteristics of characid fish species (Teleostei... 469 Reproductive characteristics of characid fish species (Teleostei, Characiformes) and their relationship with body size and phylogeny Marco A. Azevedo Setor de Ictiologia, Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, Rua Dr. Salvador França, 1427, 90690-000 Porto Alegre, RS, Brazil. ([email protected]) ABSTRACT. In this study, I investigated the reproductive biology of fish species from the family Characidae of the order Characiformes. I also investigated the relationship between reproductive biology and body weight and interpreted this relationship in a phylogenetic context. The results of the present study contribute to the understanding of the evolution of the reproductive strategies present in the species of this family. Most larger characid species and other characiforms exhibit a reproductive pattern that is generally characterized by a short seasonal reproductive period that lasts one to three months, between September and April. This is accompanied by total spawning, an extremely high fecundity, and, in many species, a reproductive migration. Many species with lower fecundity exhibit some form of parental care. Although reduction in body size may represent an adaptive advantage, it may also require evolutionary responses to new biological problems that arise. In terms of reproduction, smaller species have a tendency to reduce the number of oocytes that they produce. Many small characids have a reproductive pattern similar to that of larger characiforms. On the other hand they may also exhibit a range of modifications that possibly relate to the decrease in body size and the consequent reduction in fecundity. -

Donnelly Secretary Florida International University College of Arts & Sciences 11200 SW 8th St. - ECS 450 Miami, FL 33199 [email protected] 305.348.1235 1 July 2012 The ASIH Board of Governor's is scheduled to meet on Wednesday, 8 August 2012 from 5:00 – 7:00 pm in the Student Union Building, Rooms 207/209 at the University of British Columbia. President Beaupre plans to move blanket acceptance of all reports included in this book that cover society business for 2011 and 2012 (in part). The book includes the ballot information for the 2012 elections (Board of Governors Election and General Election held during the Annual Business Meeting). Governors can ask to have items exempted from blanket approval. These exempted items will be acted upon individually. We will also act individually on items exempted by the Executive Committee. Please remember to bring this booklet with you to the meeting. I will ship a few extra copies to Vancouver for the meeting. Please contact me directly (email is best - [email protected]) with any questions you may have. Please notify me if you will not be able to attend the meeting (if you have not contacted me yet) so I can share your regrets with the Governors. I will leave for Vancouver on 7 August so try to contact me before that date if possible. The Annual Business Meeting will be held on Sunday 12 August 2012 from 6:00 to 8:00 pm in The Gage Common Block (please consult the schedule for the room number for the meeting as it has not yet been determined). -
