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. -

Diagnostic characters of the cryptoniscus larva are illus- trated with scanning electron microscopy and the mature female and epicari- dium larva are described. The mature female exhibits characteristics typical of most species in the genus, especially those parasitic on pseudionine bopyrids. The epicaridium larva differs from other described Cabiropidae in details of the appendages and in the possession of a prominent anal tube.

Additions to and Revisions of the Amphipod (Crustacea: Amphipoda) Fauna of South Africa, with a List of Currently Known Species from the Region
Additions to and revisions of the amphipod (Crustacea: Amphipoda) fauna of South Africa, with a list of currently known species from the region Rebecca Milne Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa & Charles L. Griffiths* Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa E-mail: [email protected] (with 13 figures) Received 25 June 2013. Accepted 23 August 2013 Three species of marine Amphipoda, Peramphithoe africana, Varohios serratus and Ceradocus isimangaliso, are described as new to science and an additional 13 species are recorded from South Africa for the first time. Twelve of these new records originate from collecting expeditions to Sodwana Bay in northern KwaZulu-Natal, while one is an introduced species newly recorded from Simon’s Town Harbour. In addition, we collate all additions and revisions to the regional amphipod fauna that have taken place since the last major monographs of each group and produce a comprehensive, updated faunal list for the region. A total of 483 amphipod species are currently recognized from continental South Africa and its Exclusive Economic Zone . Of these, 35 are restricted to freshwater habitats, seven are terrestrial forms, and the remainder either marine or estuarine. The fauna includes 117 members of the suborder Corophiidea, 260 of the suborder Gammaridea, 105 of the suborder Hyperiidea and a single described representative of the suborder Ingolfiellidea. -

Data collected by the Sample Analysis at Mars (SAM) instrument on the Curiosity Rover can be integrated with Mars analog work in order to better understand the fixation and mobility of nitrogen on Mars, and thus its availability to putative biology. In particular, the relationship between nitrate and other soluble salts may help reveal the timing of nitrogen fixation and post-depositional behavior of nitrate on Mars. In addition, in situ measurements of nitrogen abundance and isotopic composition may be used to model atmospheric conditions on early Mars. Methods: The data presented are from analyses of solid Martian drilled and scooped samples by the Sam- ple Analysis at Mars (SAM) instrument suite on the Mars Science Laboratory (MSL) Curiosity Rover. SAM performs evolved gas analysis (EGA), in which a 3 Figure 1. -
A Draft Genome and Target Capture Probes for Limacina Bulimoides, Tested for Cross-Species Relevance Le Qin Choo1,2*† , Thijs M
Choo et al. BMC Genomics (2020) 21:11 https://doi.org/10.1186/s12864-019-6372-z RESEARCH ARTICLE Open Access Novel genomic resources for shelled pteropods: 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. -

SMPs are defined such that they would be suffi- ciently long-lived so as to still exist in the cosmos either as Big Bang relics or secondary collision products, and sufficiently massive such that they are typically beyond the reach of any conceiv- able accelerator-based experiment. The discovery of SMPs would address a number of important questions in modern physics, such as the origin and composition of dark matter and the unifi- cation of the fundamental forces. This review outlines the scenarios predicting SMPs and the techniques used at non-collider experiments to look for SMPs in cosmic rays and bound in mat- ter. The limits so far obtained on the fluxes and matter densities of SMPs which possess various detection-relevant properties such as electric and magnetic charge are given.

UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF SCIENCE SCHOOL OF OCEAN AND EARTH SCIENCE Doctor of Philosophy REPRODUCTIVE SUCCESS IN ANTARCTIC MARINE INVERTEBRATES By Laura Joanne Grange The nearshore Antarctic marine environment is unique, characterised by low but constant temperatures that contrast with an intense peak in productivity. As a result of this stenothermal environment, energy input has a profound ecological effect. These conditions have developed over several millions of years and have resulted in an animal physiology that is highly stenothermal and sometimes closely coupled with the seasonal food supply, e.g.
