ZooKeys 462: 11–26. doi: 10.3897/zookeys.462.6790 Abstract Bivalve mollusk shells were collected in 2350 m depth in the Beaufort Sea, Arctic Ocean off northern Alaska. Initial identification suggested the specimens were a member of the bivalve family Thyasiridae, but no known eastern Pacific or Arctic living or fossil thyasirid resembled these deep-water specimens. Comparisons were made with the type of the genera Maorithyas Fleming, 1950, Spinaxinus Oliver & Holmes, 2006, Axinus Sowerby, 1821, and Parathyasira Iredale, 1930. We determined the Beaufort Sea species represents a new genus, herein described as Wallerconcha. These specimens also represent a new species, herein named Wallerconcha sarae.

Tenorio2, Carlos M. L.

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.

  • Metagenomic Analysis Suggests Broad Metabolic Potential in Extracellular Symbionts of the Bivalve Thyasira Cf
    McCuaig et al. Animal Microbiome (2020) 2:7 Animal Microbiome https://doi.org/10.1186/s42523-020-00025-9 RESEARCH ARTICLE Open Access Metagenomic analysis suggests broad metabolic potential in extracellular symbionts of the bivalve Thyasira cf. gouldi Bonita McCuaig1, Lourdes Peña-Castillo1,2 and Suzanne C. Dufour1* Abstract Background: Next-generation sequencing has opened new avenues for studying metabolic capabilities of bacteria that cannot be cultured. Here, we provide a metagenomic description of chemoautotrophic gammaproteobacterial symbionts associated with Thyasira cf. gouldi, a sediment-dwelling bivalve from the family Thyasiridae. Thyasirid symbionts differ from those of other bivalves by being extracellular, and recent work suggests that they are capable of living freely in the environment. Results: Thyasira cf. gouldi symbionts appear to form mixed, non-clonal populations in the host, show no signs of genomic reduction and contain many genes that would only be useful outside the host, including flagellar and chemotaxis genes. The thyasirid symbionts may be capable of sulfur oxidation via both the sulfur oxidation and reverse dissimilatory sulfate reduction pathways, as observed in other bivalve symbionts. In addition, genes for hydrogen oxidation and dissimilatory nitrate reduction were found, suggesting varied metabolic capabilities under a range of redox conditions. The genes of the tricarboxylic acid cycle are also present, along with membrane bound sugar importer channels, suggesting that the bacteria may be mixotrophic. Conclusions: In this study, we have generated the first thyasirid symbiont genomic resources. In Thyasira cf. gouldi, symbiont populations appear non-clonal and encode genes for a plethora of metabolic capabilities; future work should examine whether symbiont heterogeneity and metabolic breadth, which have been shown in some intracellular chemosymbionts, are signatures of extracellular chemosymbionts in bivalves.

  • 2014 Annual Report Santa Barbara Museum of Natural History 2014 Was an Exciting Year for the Museum and Sea Center
    2014 ANNUAL REPORT SANTA BARBARA MUSEUM OF NATURAL HISTORY 2014 was an exciting year for the Museum and Sea Center. We had strong attendance at both campuses. The Sea Center had over 97,000 visitors last year, the highest on record and we are confident we will pass the 100,000 mark in 2015. Financially, we outperformed our 2014 budget, both on the revenue and on the expense side. And our endowment grew by almost $1 million last year. We unveiled our new tide pool installation at the Sea Center and we opened our Curiosity Lab at the Mission Canyon campus. Both of these new spaces are exciting and transformative peeks into our future. In September, we held our second Symposium on Human Origins and the scientists that came from all over the world to participate drew full houses at each of the two day sessions both at the Museum and downtown at the Lobero Theatre. A number of important collections were also gifted to the Museum. A butterfly collection comprising almost every species found here in California. Another collection consisting of 920 fossil ammonites was gifted to us. Three significant shell collections arrived as well as a number of important rare books that were gifted to the library. Numerous smaller collections also arrived which fill out our holdings. In March of 2014 we submitted our Master Plan and updated Conditional Use Permit application to the City of Santa Barbara; these were unanimously approved by the Planning Commission in early January of 2015 with Elisabeth Fowler, Chair HONORARY tremendous community support.

ZooKeys 963: 1–36. https://doi.org/10.3897/zookeys.963.52234 Abstract An increase in richness of benthic marine mollusks towards high latitudes has been described on the Pacific coast of Chile in recent decades. This considerable increase in diversity occurs specifically at the beginning of the Magellanic Biogeographic Province. Within this province lies the Strait of Magellan, considered the most important channel because it connects the South Pacific and Atlantic Oceans. These characteristics make it an interesting area for marine research; thus, the Strait of Magellan has histori- cally been the area with the greatest research effort within the province.

Imhoff1,*, Heiko Sahling2, Jörg Süling1, Thomas Kath1 1Institut für Meereskunde, Düsternbrooker Weg 20, 24105 Kiel, Germany 2GEOMAR Research Center for Marine Geoscience, Wischhofstraße 1–3, 24148 Kiel, Germany ABSTRACT: The phylogenetic relationship of sulphur-oxidising endosymbiotic bacteria from bivalves of the families Vesicomyidae (Calyptogena sp. C1, Calyptogena sp. C3), Solemyidae (Acharax sp.) and Thyasiridae (Conchocele sp.) from cold-seep habitats were determined by 16S rDNA nucleotide sequence analyses. The endosymbiotic bacteria form distinct groups within the gamma-Proteobacteria and are well separated from each other and from free-living sulphur- oxidising bacteria of the genera Beggiatoa, Halothiobacillus and Thiomicrospira. The endosymbiotic bacteria of Acharax sp. from cold seeps off Oregon, Indonesia and Pakistan have sequences highly similar to each other but quite distinct from other thiotrophic endosymbionts. This includes endosym- bionts from Solemya spp., to which they are distantly related. Symbiotic bacteria of Conchocele sp. from a cold seep in the Sea of Okhotsk are similar to those of Bathymodiolus thermophilus and related species, as shown by their overall sequence similarity and by signature sequences. The endosymbiotic bacteria of Calyptogena spp. from cold seeps off Oregon and Pakistan are closely related to those of other vesicomyids. Endosymbiont species found off Oregon corresponded to 2 different clusters of Calyptogena spp. symbionts in the same samples. The results corroborate the hypothesis of a monophyletic origin of the symbionts in vesicomyid clams, and support the existence of deeply branching groups in solemyid symbionts and of divergent lines and distribution for thyasirid symbionts.

Antibodies elicited by the purified (-550 kDa) composed of eight large subunits and eight small large subunit of RbuP2Case from tobacco (Nicotana tabacum) subunits, with molecular masses of 50-56 kDa and 11-15 cross-reacted on immunoblots with a protein ofsimilar molecular kDa, respectively (3, 4). The enzyme catalyzes both car- mass occurring in extracts ofthe symbiont-containing gill tissue of boxylation and oxygenation reactions by using ribulose S. velum. No cross-reactivity was detected in symbiont-free tissue 1,5-bisphosphate as a substrate. Although the function ofthe extracts.

    Osca et al. BMC Evolutionary Biology 2014, 14:197 http://www.biomedcentral.com/1471-2148/14/197 RESEARCH ARTICLE Open Access The complete mitochondrial genome of Scutopus ventrolineatus (Mollusca: Chaetodermomorpha) supports the Aculifera hypothesis David Osca1, Iker Irisarri1,2, Christiane Todt3, Cristina Grande4 and Rafael Zardoya1* Abstract Background: With more than 100000 living species, mollusks are the second most diverse metazoan phylum. The current taxonomic classification of mollusks recognizes eight classes (Neomeniomorpha, Chaetodermomorpha, Polyplacophora, Monoplacophora, Cephalopoda, Gastropoda, Bivalvia, and Scaphopoda) that exhibit very distinct body plans. In the past, phylogenetic relationships among mollusk classes have been contentious due to the lack of indisputable morphological synapomorphies. Fortunately, recent phylogenetic analyses based on multi-gene data sets are rendering promising results. In this regard, mitochondrial genomes have been widely used to reconstruct deep phylogenies. For mollusks, complete mitochondrial genomes are mostly available for gastropods, bivalves, and cephalopods, whereas other less-diverse lineages have few or none reported. Results: ThecompleteDNAsequence (14662 bp) of the mitochondrial genome of the chaetodermomorph Scutopus ventrolineatus Salvini-Plawen, 1968 was determined. Compared with other mollusks, the relative position of protein-coding genes in the mitochondrial genome of S. ventrolineatus is very similar to those reported for Polyplacophora, Cephalopoda and early-diverging lineages of Bivalvia and Gastropoda (Vetigastropoda and Neritimorpha; but not Patellogastropoda). The reconstructed phylogenetic tree based on combined mitochondrial and nuclear sequence data recovered monophyletic Aplacophora, Aculifera, and Conchifera. Within the latter, Cephalopoda was the sister group of Gastropoda and Bivalvia + Scaphopoda. Conclusions: Phylogenetic analyses of mitochondrial sequences showed strong among-lineage rate heterogeneity that produced long-branch attraction biases.
