Las Palmeras # 3425, Ñuñoa. Chile e-mail: [email protected] Ibáñez C. M and Elie Poulin. 204. Genetic structure and diversity of squids with contrasting life histories in the Humboldt Current System. Hidrobiológica 24 (): -0. ABSTRACT Dosidiscus gigas and Doryteuthis gahi are the most abundant squids in the Humboldt Current System (HCS). These species have contrasting life histories. To determine the genetic structure and diversity of these species, we collected samples from different places in the HCS and amplified a fragment of the mitochondrial cytochrome C oxidase I gene. The molecular analysis of D. gigas revealed low genetic diversity, absence of population structure and evidence for a demographic expansion during the transition from the last glacial period to the current interglacial. These results sug- gest that D. gigas is composed of one large population with high levels of gene flow throughout the HCS. In the case of D. gahi, the sequences indicated the presence of two population units in the HCS, one in south-central Chile and one in Peru. The Chilean unit had greater genetic diversity, suggesting that it is an old, relatively stable population. In the Peruvian unit there was less genetic diversity and evidence of a recent demographic expansion. -

Offspring Size, Provisionin a Function of Maternal in Developing Fspring Size
Offspring size, provisioning and performance as a function of maternal investment in direct developing whelks By Sergio Antonio Carrasco Órdenes A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy in Marine Biology Victoria University of Wellington Te Whare Wānanga o te Ūpoko o te Ika a Māui 2012 This thesis was conducted under the supervision of: Dr. Nicole E. Phillips (Primary Supervisor) Victoria University of Wellington Wellington, New Zealand and Dr. Mary A. Sewell (Secondary Supervisor) The University of Auckland Auckland, New Zealand Abstract Initial maternal provisioning has pervasive ecological and evolutionary implications for species with direct development, influencing offspring size and energetic content, with subsequent effects on performance, and consequences in fitness for both offspring and mother. Here, using three sympatric marine intertidal direct developing gastropods as model organisms (Cominella virgata, Cominella maculosa and Haustrum scobina) I examined how contrasting strategies of maternal investment influenced development, hatchling size, maternal provisioning and juvenile performance. In these sympatric whelks, duration of intra-capsular development was similar among species (i.e. 10 wk until hatching); nonetheless, differences in provisioning and allocation were observed. Cominella virgata (1 embryo per capsule; ~3 mm shell length [SL]) and C. maculosa (7.7 ± 0.3 embryos per capsule; ~1.5 mm SL) provided their embryos with a jelly-like albumen matrix and all embryos developed. Haustrum scobina encapsulated on average 235 ± 17 embryos per capsule but only ~10 reached the hatching stage (~1.2 mm SL), with the remaining siblings being consumed as nurse embryos, mainly during the first 4 wk of development. -
Imposex En Crassilabrum Crassilabrum (Neogastropoda: Muricidae) En La Costa Central Del Perú
Rev Inv Vet Perú 2017; 28(4): 834-842 http://dx.doi.org/10.15381/rivep.v28i4.13873 Imposex en Crassilabrum crassilabrum (Neogastropoda: Muricidae) en la Costa Central del Perú IMPOSEX IN CRASSILABRUM CRASSILABRUM (NEOGASTROPODA: MURICIDAE) IN THE PERUVIAN CENTRAL COAST Rolf Rivas1, Renzo Pradel1, Soledad Hurtado1, Dayanne Cornelio1, Jorge Mendoza1, Angélica Guabloche1, José Iannacone2,3, Lorena Alvariño1, Luz Castañeda1 RESUMEN El imposex es un fenómeno que consiste en el desarrollo de caracteres sexuales masculinos sobre el sistema reproductivo de las hembras de caracoles gasterópodos por la contaminación por compuestos organoestañosos (OTs), como el tributil estaño (TBT). En el presente trabajo se evaluó el imposex en Crassilabrum crassilabrum Sowerby, 1834 (Neogastropoda: Muricidae) proveniente de la costa central del Perú, para lo cual se analizaron individuos colectados de la zona intermareal de Pucusana y Ancón, Lima. Se tomaron medidas biométricas y se calcularon los índices de imposex. El porcentaje de imposex en Ancón fue del 98% y en Pucusana de 100%. El índice de la longitud relativa del pene (RPLI) fue de 52.3% y 44.5% para Pucusana y Ancón, respectivamente. Una relación significativa fue encontrada entre la longitud de la conchilla y la longitud del pene en machos en ambas playas, pero no así en las hembras. Crassilabrum crassilabrum es un molusco con aplicación para emplearse como un bioindicador de componentes OTs en la costa central del Perú y en el Pacífico sudamericano. Palabras clave: Crassilabrum crassilabrum; imposex; organoestañosos; Pacífico Sur; Perú; caracol ABSTRACT The imposex is a phenomenon that consists in the development of masculine sexual characteristics on the reproductive system of the gastropod female snails by organotin compounds (OTs), like tributyl tin (TBT). -

Gayana 73(1): 17-27, 2009 ISSN 0717-652X MOLECULAR ANALYSIS IN CHILEAN COMMERCIAL GASTROPODS BASED ON 16S rRNA, COI AND ITS1-5.8S rDNA-ITS2 SEQUENCES ANALISIS MOLECULAR EN GASTROPODOS CHILENOS COMERCIALES BASADOS EN LAS SECUENCIAS 16S rRNA,. COI Y ITS1-5.8S rDNA-ITS2 Felipe Aguilera-Muñoz, Fabiola Lafarga-Cruz & Cristian Gallardo-Escárate* Laboratorio de Biotecnología Acuícola, Departamento de Oceanografía, Facultad de Ciencias Naturales y Oceanográficas, Centro de Biotecnología, Universidad de Concepción. Barrio Universitario s/n. Casilla 160-C Concepción, Chile. email: [email protected] ABSTRACT Gastropod mollusks are part of the principal marine resources cultivated and commercialized in Chile. There are native Chilean species such as loco (Concholepas concholepas), locate (Thais chocolata), trumulco snail (Chorus giganteus), keyhole limpets (Fissurella spp.), tegula snail (Tegula atra) as well as exotic species such as red abalone (Haliotis rufescens) and Japanese abalone (Haliotis discus hannai). Despite their importance as marine resources, molecular genetic studies establishing phylogenetic relationships and estimating population genetic parameters are scarce. The aim of this study is to establish a molecular approach among the main commercial gastropod species in Chile. The mitochondrial genes 16S rRNA and COI, and the nuclear ribosomal region ITS1-5.8SrDNA-ITS2 were amplified by PCR and sequencing. Alignment analysis was used to determine systematic relationships at the specific level for the species studied. The results revealed that 7 species are grouped in 4 genetically distinct families (Haliotidae, Trochidae, Muricidae and Fissurellidae). In comparison with COI sequencing, 16S rRNA and ITS1-5.8SrDNA-ITS2 sequencing were relatively more conserved with a divergence percentage for 16S rDNA and ITS1-5.8SrDNA-ITS2 of 1.2% and 1.8%, respectively, contrasting with the value of 10% obtained for COI in abalone.
