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. -

Evolutionary Patterns and Consequences of Developmental Mode in Cenozoic Gastropods from Southeastern Australia
Evolutionary patterns and consequences of developmental mode in Cenozoic gastropods from southeastern Australia Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by Kirstie Rae Thomson September 2013 ABSTRACT Gastropods, like many other marine invertebrates undergo a two-stage life cycle. As the adult body plan results in narrow environmental tolerances and restricted mobility, the optimum opportunity for dispersal occurs during the initial larval phase. Dispersal is considered to be a major influence on the evolutionary trends of different larval strategies. Three larval strategies are recognised in this research: planktotrophy, lecithotrophy and direct development. Planktotrophic larvae are able to feed and swim in the plankton resulting in the greatest dispersal potential. Lecithotrophic larvae have a reduced planktic period and are considered to have more restricted dispersal. The planktic period is absent in direct developing larvae and therefore dispersal potential in these taxa is extremely limited. Each of these larval strategies can be confidently inferred from the shells of fossil gastropods and the evolutionary trends associated with modes of development can be examined using both phylogenetic and non-phylogenetic techniques. This research uses Cenozoic gastropods from southeastern Australia to examine evolutionary trends associated with larval mode. To ensure the species used in analyses are distinct and correctly assigned, a taxonomic review of the six families included in this study was undertaken. The families included in this study were the Volutidae, Nassariidae, Raphitomidae, Borsoniidae, Mangeliidae and Turridae. Phylogenetic analyses were used to examine the relationships between taxa and to determine the order and timing of changes in larval mode throughout the Cenozoic. -

Spermatid differentiation and the morphology of mature spermatozoa in the gastropod Chorus giganteus (Lesson, 1829) were investigated. Five phases of spermiogenesis are proposed based on the polarization of organelles, nuclear elongation, and chromatin condensation. The ultrastructure of the spermatozoa of Chorus giganteus is compared to those of other Muricidae. Possible phylogenetic and functional relationships among prosobranch spermatozoa are discussed. INTRODUCTION internal fertilization; they display a threadlike head, an elongate middle piece, and mitochondria arranged around Studies dealing with spermatogenesis in mollusks have the axial filament.
