MORPHOMETRIC and PARASITOLOGICAL EVIDENCE for ONTOGENETIC and GEOGRAPHICAL DIETARY SHIFTS in INTERTIDAL FISHES Marcela Aldana, J
BULLETIN OF MARINE SCIENCE, 70(I): 55-74, 2002 MORPHOMETRIC AND PARASITOLOGICAL EVIDENCE FOR ONTOGENETIC AND GEOGRAPHICAL DIETARY SHIFTS IN INTERTIDAL FISHES Marcela Aldana, Jose M. Pulgar, Fernando Ogalde and F PatricioOjeda ABSTRACT Studies on the feeding ecology of intertidal fish assemblages have indicated the exist- ence of three trophic groups: herbivores, omnivores and carnivores. This classification has enabled researchers to establish some ecological relationships among their compo- nents. However, temporal and spatial variations in the use of food resources have rarely been addressed. In this study, ontogenetic and geographical variations in the diet of two intertidal fish species: Girella laevifrons and Graus nigra were evaluated through an integrative analysis of their diet, relation between intestinal length/body length, and their parasite fauna. Results of this combined analysis suggest ontogenetic and geographical variations in the diet of G. laevifrons. In G. nigra, no evidence of ontogenetic dietary shifts was found, but marked differences in diet were detected among localities. How- ever, parasitological evidence does not reflect the geographical differences in its diet. Omnivory of G. nigra at two localities (viz Caleta Errazuriz and El Tabo) may be indica- :ive of the opportunistic nature of this species related to the greater availability of nacroalgae at these localities. The assessment of intestinal length of G. nigra highlights the importance of considering macroalgal species composition, and not only their abun- dance as a group, when estimating the quality of the diet of a given fish species. In general, the geographical differences in diet, length of the intestine and parasitofauna of G. laevifrons and G. -

In the present study, we compared the pattern in the helminth community of three sympatric wild rodent species Akodon cursor, A. montensis and Oligoryzomys nigripes using numerical abundance and biomass approaches. The cestode Rodentolepis akodontis was the worm with highest biomass in the three rodents. The trichostrongylid Stilestrongylus lanfrediae presented highest biomass in O. nigripes and represented 70% of the total numeric abundance of parasites. Interestingly, for Akodon spp. the species with more biomass represented less than 10% of the total numerical abundance. Parasites with the higher numeric abundance do not have the largest body size. Although the biomass pattern is different from numeric abundance, this difference does not influence in the helminth distribution community among the three sympatric hosts. -

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. -

La reineta Brama australis es un importante recurso pesquero artesanal en la zona central chilena, incorporado en los programas de seguimiento biológico, pero con escasas evaluaciones de sus aspectos tróficos. Para actualizar el estado del conocimiento, se analizó su dieta durante el verano austral época de mayor disponibilidad de este recurso en la zona central de Chile, mediante el análisis del contenido gástrico de 300 ejemplares capturados entre noviembre 2011 y marzo 2012. Se identificó una dieta dominada por Euphausia mucronata (IIR = 92,33), aunque a escala mensual se identificó una dieta mixta de E. mucronata durante noviembre, diciembre 2011 y marzo 2012, además de Pterygosquilla armata y anfípodos hipéridos durante enero y marzo 2012. No se encontró diferencias significativas entre ambos sexos (P > 0,01). Estos resultados demuestran y corroboran que B. australis es un depredador pelágico con un reducido espectro trófico en el litoral de Chile central.

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.
