Life Cycle and Early Development of the Thecosomatous Pteropod Limacina Retroversa in the Gulf of Maine, Including the Effect of Elevated CO2 Levels

Lawsona and Ann M. Tarranta a. Biology Department, Woods Hole Oceanographic Institution, Woods Hole, MA 02543 b. Zoology Dept., Faculty of Science, Al-Azhar University in Assiut, Assiut, Egypt. c. Bermuda Institute of Ocean Sciences, St. George’s GE01, Bermuda *Corresponding Author, equal contribution with lead author Email: [email protected] Phone: 441-297-1880 x131 Keywords: mollusc, ocean acidification, calcification, mortality, developmental delay Abstract Thecosome pteropods are pelagic molluscs with aragonitic shells. They are considered to be especially vulnerable among plankton to ocean acidification (OA), but to recognize changes due to anthropogenic forcing a baseline understanding of their life history is needed. In the present study, adult Limacina retroversa were collected on five cruises from multiple sites in the Gulf of Maine (between 42° 22.1’–42° 0.0’ N and 69° 42.6’–70° 15.4’ W; water depths of ca. 45–260 m) from October 2013−November 2014. They were maintained in the laboratory under continuous light at 8° C. There was evidence of year-round reproduction and an individual life span in the laboratory of 6 months. Eggs laid in captivity were observed throughout development. Hatching occurred after 3 days, the veliger stage was reached after 6−7 days, and metamorphosis to the juvenile stage was after ~ 1 month. Reproductive individuals were first observed after 3 months. Calcein staining of embryos revealed calcium storage beginning in the late gastrula stage. -
A Draft Genome and Target Capture Probes for Limacina Bulimoides, Tested for Cross-Species Relevance Le Qin Choo1,2*† , Thijs M

P. Bal3†, Marvin Choquet3, Irina Smolina3, Paula Ramos-Silva1, Ferdinand Marlétaz4, Martina Kopp3, Galice Hoarau3 and Katja T. C. A. Peijnenburg1,2* Abstract Background: Pteropods are planktonic gastropods that are considered as bio-indicators to monitor impacts of ocean acidification on marine ecosystems. In order to gain insight into their adaptive potential to future environmental changes, it is critical to use adequate molecular tools to delimit species and population boundaries and to assess their genetic connectivity. We developed a set of target capture probes to investigate genetic variation across their large-sized genome using a population genomics approach. Target capture is less limited by DNA amount and quality than other genome-reduced representation protocols, and has the potential for application on closely related species based on probes designed from one species. Results: We generated the first draft genome of a pteropod, Limacina bulimoides, resulting in a fragmented assembly of 2.9 Gbp. Using this assembly and a transcriptome as a reference, we designed a set of 2899 genome- wide target capture probes for L. bulimoides. The set of probes includes 2812 single copy nuclear targets, the 28S rDNA sequence, ten mitochondrial genes, 35 candidate biomineralisation genes, and 41 non-coding regions. The capture reaction performed with these probes was highly efficient with 97% of the targets recovered on the focal species. -

They are part of the class Gastropoda and located in the order Ophistobranchia. The pteropods are divided into the orders Thecosomata and Gymnosomata. They are small to medium sized animals, ranging from little more than 1mm for example in many members of the Genus Limacina to larger species such as Cymbulia peroni, which reaches a pseudoconch length of 65mm. The mostly shell bearing Thecosomata are known from about 74 recent species worldwide and are divided into five families. The Limacinidae are small gastropods with a sinistrally coiled shell; they can completely retract their body into the shell. Seven recent species of the genus Limacina are known. The Cavoliniidae is the largest of the thecosomate families with about 47 species with quite unusually formed shells. -

Utility of H3-Genesequences for Phylogenetic Reconstruction – a Case Study of Heterobranch Gastropoda –*

W. Goethe-University, Frankfurt am Main, Germany *Paper presented to the 2nd International Workshop on Opisthobranchia, ZFMK, Bonn, Germany, September 20th to 22nd, 2006 Abstract. In the present study we assessed the utility of H3-Genesequences for phylogenetic reconstruction of the He- terobranchia (Mollusca, Gastropoda). Therefore histone H3 data were collected for 49 species including most of the ma- jor groups. The sequence alignment provided a total of 246 sites of which 105 were variable and 96 parsimony informa- tive. Twenty-four (of 82) first base positions were variable as were 78 of the third base positions but only 3 of the se- cond base positions. H3 analyses showed a high codon usage bias. The consistency index was low (0,210) and a substitution saturation was observed in the 3r d codon position. The alignment with the translation of the H3 DNA sequences to amino-acid sequences had no sites that were parsimony-informative within the Heterobranchia. Phylogenetic trees were reconstructed using maximum parsimony, maximum likelihood and Bayesian methodologies. Nodilittorina unifasciata was used as outgroup. The resolution of the deeper nodes was limited in this molecular study. The data themselves were not sufficient to clar- ify phylogenetic relationships within Heterobranchia. Neither the monophyly of the Euthyneura nor a step-by-step evo- lution by the “basal” groups was supported. -

No general list of Maine shells—including land, fresh-water and marine species—-has been published since 1843, when Dr. J. W. Mighels’ list was printed in the Boston Journal of Natural History. Dr. Mighels may be called the “Pioneer” conchologist of Maine. By profession a physician, in his leisure hours he was a most enthusiastic collector and student of all forms of molluscan life. Enthusiasm such as his was “contagious” and he soon had gathered about him a little band of active students and collectors. Of these Capt. Walden of the U. S. Revenue Cutter “Morris” was dredging in deep water and exploring the eastern shores and among the islands, and “by his zeal procured many rare species;” Dr. -

Wiebe13 · Agata Weydmann‑Zwolicka14 Received: 6 February 2021 / Accepted: 18 April 2021 © The Author(s) 2021 Abstract Characterization of species diversity of zooplankton is key to understanding, assessing, and predicting the function and future of pelagic ecosystems throughout the global ocean. The marine zooplankton assemblage, including only metazoans, is highly diverse and taxonomically complex, with an estimated ~28,000 species of 41 major taxonomic groups. This review provides a comprehensive summary of DNA sequences for the barcode region of mitochondrial cytochrome oxidase I (COI) for identifed specimens. The foundation of this summary is the MetaZooGene Barcode Atlas and Database (MZGdb), a new open-access data and metadata portal that is linked to NCBI GenBank and BOLD data repositories. The MZGdb provides enhanced quality control and tools for assembling COI reference sequence databases that are specifc to selected taxonomic groups and/or ocean regions, with associated metadata (e.g., collection georeferencing, verifcation of species identifcation, molecular protocols), and tools for statistical analysis, mapping, and visualization. To date, over 150,000 COI sequences for ~ 5600 described species of marine metazoan plankton (including holo- and meroplankton) are available via the MZGdb portal.
