ZooKeys 604: 13–30. doi: 10.3897/zookeys.604.8976 Abstract The Atlantidae (shelled heteropods) is a family of microscopic aragonite shelled holoplanktonic gastro- pods with a wide biogeographical distribution in tropical, sub-tropical and temperate waters. The arago- nite shell and surface ocean habitat of the atlantids makes them particularly susceptible to ocean acidifica- tion and ocean warming, and atlantids are likely to be useful indicators of these changes. However, we still lack fundamental information on their taxonomy and biogeography, which is essential for monitoring the effects of a changing ocean. -

Conids are well known for being active predators on worms, fishes, and even other snails. Cones are venomous gastropods, meaning that they use a sophisticated cocktail of hundreds of toxins, named conotoxins, to subdue their prey. Although this venom has been studied for decades, most of the effort has been focused on Indo-Pacific species. Thus far, Atlantic species have received little attention despite recent radiations have led to a hotspot of diversity in West Africa, with high levels of endemic species. In fact, the Atlantic Chelyconus ermineus is thought to represent an adaptation to piscivory independent from the Indo-Pacific species and is, therefore, key to understanding the basis of this diet specialization. We studied the transcriptomes of the venom gland of three individuals of C. ermineus. The venom repertoire of this species included more than 300 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity. -
Comparative Analysis of Chromosome Counts Infers Three Paleopolyploidies in the Mollusca
GBE Comparative Analysis of Chromosome Counts Infers Three Paleopolyploidies in the Mollusca Nathaniel M. Hallinan* and David R. Lindberg Department of Integrative Biology, University of California Berkeley *Corresponding author: E-mail: [email protected]. Accepted: 8 August 2011 Abstract The study of paleopolyploidies requires the comparison of multiple whole genome sequences. If the branches of a phylogeny on which a whole-genome duplication (WGD) occurred could be identified before genome sequencing, taxa could be selected that provided a better assessment of that genome duplication. Here, we describe a likelihood model in which the number of chromosomes in a genome evolves according to a Markov process with one rate of chromosome duplication and loss that is proportional to the number of chromosomes in the genome and another stochastic rate at which every chromosome in the genome could duplicate in a single event. We compare the maximum likelihoods of a model in which the genome duplication rate varies to one in which it is fixed at zero using the Akaike information criterion, to determine if a model with WGDs is a good fit for the data. Once it has been determined that the data does fit the WGD model, we infer the phylogenetic position of paleopolyploidies by calculating the posterior probability that a WGD occurred on each branch of the taxon tree. Here, we apply this model to a molluscan tree represented by 124 taxa and infer three putative WGD events. In the Gastropoda, we identify a single branch within the Hypsogastropoda and one of two branches at the base of the Stylommatophora. -

Relying Atlantidae on a small (< 14 mm), delicate aragonite shell and living in the upper ocean means that, in common with Atlanta pteropods, atlantids are likely to be affected by imminent ocean changes. Variable shell morphology and Cytochrome c oxidase subunit 1 (mtCO1) widespread distributions indicate that the family is more diverse than the 23 currently known species. DNA barcoding Uncovering this diversity is fundamental to determining the distribution of atlantids and to understanding Planktonic gastropods their environmental tolerances. -

Patterns of Vertical Distribution in Epipelagic Heteropod Molluscs Off Hawaii
Vol. 60: 235-246, 1990 MARINE ECOLOGY PROGRESS SERIES Published February 22 Mar. Ecol. Prog. Ser. Patterns of vertical distribution in epipelagic heteropod molluscs off Hawaii Roger R. Seapy Department of Biological Science, California State University, Fullerton, California 92634, USA ABSTRACT: Die1 patterns of vertical distribution were assessed for 13 species of heteropod molluscs from the epipelagic zone off Hawaii. Replicated series of oblique tows were taken through 5 depth intervals to 300 m using opening-closing, 70 cm Bongo nets during day and night periods. Two species (Atlanta fusca and Oxygyrus keraudreni) were restricted to the upper 90 m of the water column and were captured in low numbers. Five species (A. lesueuri, A. inflata, Firoloida desmaresti, A. helicinoides and A. oligogyra) ranged from the surface to 140 m during either or both diel periods. There were no evident diel differences in vertical distribution among these species, with the exception of A. helicinoides, which appeared to undergo a limited upward migration at night. Three species (Protat- lanta souleyeti, A. turriculata and A. plana) had daytime distributions extending to 200 m. Limited upward migrations at night were suggested for the latter 2 species. Lastly, 3 species (Pterotrachea hippocampus, A. peroni and A. meteori) ranged below 200 m during the day. These species achieved the largest sizes recorded in this study in their respective families, and exhibited upward nocturnal migrations. A series of 6 oblique, open-net tows to a target depth of 50 m with 70 cm Bongo nets and a 4 mLring net suggested that several species are capable of daytime net avoidance, implying that the low daytime densities recorded for these species from shallow waters during the vertical distribution study could have represented, at least in part, sampling artifacts.
