Population Connectivity of the Corallivorous Gastropod Coralliophila Abbreviata: Larval Dispersal Potential and Genetic Structure Population connectivity of the corallivorous gastropod Coralliophila abbreviata: larval dispersal potential and genetic structure Lyza Johnston University of Miami Rosenstiel School of Marine and Atmospheric Science 4600 Rickenbacker Causeway Miami, FL 33149 NOAA Award Number: NA07NMF4630096 Reporting Period: 7/1/07 - 12/31/09 Final Report Abstract. Coralliophila abbreviata (Lamarck) is a coral-eating gastropod found throughout the Caribbean and Western Atlantic. These snails cause substantial and chronic mortality of the two ESA listed ‘Threatened’ scleractinian coral species, Acropora palmata and A. cervicornis. The objectives of this project were to 1) determine the species status of Coralliophila abbreviata 2) estimate the dispersal potential of C. abbreviata veligers by determining the adult reproductive season and frequency, planktonic larval duration, larval settlement behavior and 3) estimate actual gene flow among C. abbreviata populations on a Caribbean-wide scale, using novel, highly polymorphic molecular markers (microsatellites). Eight polymorphic microsatellite loci of C. abbreviata were isolated and then characterized using 60 C. abbreviata from two geographically disparate populations (Key Largo, FL USA and the Grenadines). All loci were highly polymorphic with an average number of alleles per locus of 24 (range 13-34). Observed and expected heterozygosity values ranged from 0.375 - 0.969 and 0.877 - 0.981, respectively. Three loci deviated significantly from Hardy-Weinberg equilibrium in both populations, presumably due to null alleles. No linkage disequilibrium between pairs of loci was detected A total of 211 C. abbreviata from three coral host taxa and five geographical locations, spanning the species range, have been genotyped using the five loci that conformed to HW expectations. The mitochondrial Cytochrome b gene was sequenced for 82 individuals from two coral host taxa and three geographical locations. No significant genetic structure among hosts or geographically disparate populations was found, indicating that C. abbreviata is one plastic species with high population connectivity. Settlement assays were unsuccessful as culturing and raising C. abbreviata veliger larvae to competence and metamorphosis proved difficult. However, we did maintain a batch of larvae swimming in the water column for approximately 32 days. Little shell growth and no metamorphosis were observed. Such a protracted pelagic larval duration may be suitable to explain the lack of genetic structure observed for this species. Monthly in situ sampling of female C. abbreviata to ascertain reproductive patterns was abandoned as we wished to collect only one or two females from each coral colony throughout the study period to avoid complications with socially induced sex change of these sequential hermaphrodites and we could not locate enough infested Acropora palmata colonies in the study area support this sampling scheme. Therefore, we were only able to collect females every one to two months for a six month period. Females reproduced throughout the observed six month period and, although the degree of difference was variable, the proportion of females brooding egg capsules was consistently lower for snail populations found on Montastraea spp. than on A. palmata. These data support the hypothesis that snail populations feeding on acroporid corals have higher fitness than those feeding on other corals. This project has generated valuable information on the population genetic structure, reproductive patterns and early life-history of C. abbreviata, which to our knowledge, has not been previously reported. Furthermore, the first microsatellite markers were developed for C. abbreviata and thus constitute a valuable tool set that can be used to address a multitude of ecological and evolutionary questions for this species. NARRATIVE Reproductive Season and Frequency Population dynamics, connectivity, and genetic structure of a species are all highly dependent on adult reproductive biology (mode, season, and frequency of reproduction, and fecundity). For C. abbreviata, brood size increases as a power function with female shell length (Johnston and Miller 2007). Females feeding on acroporid corals reach larger sizes than those feeding on other prey species (Hayes 1990; Bruckner et al. 1997; Baums et al. 2003; Johnston and Miller 2007) and thus, on average, produce more offspring (Johnston and Miller 2007). However, very little is known about the reproductive patterns of C. abbreviata such as seasonality or frequency of reproduction or the variation in these patterns among snail populations on different coral hosts. The objective of this component of the project was to assess seasonal and host specific patterns in reproduction of C. abbreviata. The goal was to collect female snails monthly for 12 months from two coral host taxa (A. palmata and Montastraea spp.) from multiple sites in the Florida Keys National Marine Sanctuary (FKNMS) to determine their reproductive status. However, to avoid complications with socially induced sex change of these sequential hermaphrodites, we did not want to resample groups on individual coral colonies during the study period. We thus had to depart from the planned monthly sampling scheme as we could not locate enough Acropora palmata colonies in the study area that harbored snails that were not part of a long term monitoring project that requires that snail populations remain in tact. Female snails were thus only collected in June, August, September, and November of 2007, from 10 sites in the FKNMS (Table 1). At each site, SCUBA divers searched Acropora palmata and Montastraea spp. colonies for snails. C. abbreviata are protandrous hermaphrodites that exhibit host and sex specific variation in size frequency distributions: snails on A. palmata are larger than snails on Montastraea spp., and females are larger than males on both host taxa. Thus, to increase the likelihood of collecting females, only snails larger than 30 and 20 mm shell length were collected from A. palmata and Montastraea spp., respectively (size ranges are based on data from Johnston and Miller 2007). Only 1-2 snails were collected from any one coral colony. Because female C. abbreviata often expel egg capsules during collection, snails were taken off the coral and placed immediately into individual containers for transport back to the laboratory. At the laboratory, shell length was measured with vernier calipers to the nearest 0.01 mm. Shells were crushed and the soft tissue was examined to confirm sex (absence of penis above the right eye stock or presence of egg capsules in the mantle cavity). The presence and number of egg capsules was recorded along with the developmental stage of the embryos. The following criteria were used to classify embryonic development into four sequential stages: 1.) yellow egg mass concentrated at one pole of the transparent egg capsule (early); 2.) larger yellow embryos diffuse throughout the egg capsule (mid-early); 3.) orange embryos (mid-late); 4.) dark orange/brown swimming embryos filling the egg capsule (late). Stages 1 and 2 and 3 and 4 were then grouped into early and late stage embryos, respectively (Fig. 1). The proportion of females brooding egg capsules was averaged over sites for each coral host taxa and sampling time and compared between hosts and among months using two-way analysis of variance (ANOVA; Fig. 1). Female snails from both coral hosts brooded egg capsules at every sampling time. There was no significant effect of sampling date (p = 0.562), but there was a significant effect of coral host (p < 0.01) and a significant host*date interaction (p = 0.037) on the proportion of females brooding egg capsules (Table 2; Fig. 2). Although higher frequency sampling combined with non-destructive monitoring of individual snails is needed to fully elucidate the reproductive season, number of broods per year, and the length of intracapsular development for C. abbreviata, these data provide some first insight on host-specific reproductive patterns of C. abbreviata. Females reproduced throughout the observed six month period and, although the degree of difference was variable, the proportion of females brooding egg capsules was consistently lower for snail populations found on Montastraea spp. than on A. palmata. These data support the hypothesis that snail populations feeding on acroporid corals have higher fitness than those feeding on other corals.

McClain* Monterey Bay Aquarium Research Institute, ABSTRACT 7700 Sandholdt Road, Moss Landing, CA At present, researchers propose that over 14,000 seamounts exist and, like their 95039, USA terrestrial analogues, function like islands. In addition, seamounts are described as oases, biodiversity hotspots, and lush coral/sponge gardens. Here I discuss the extent to which these tenets regarding seamounts may be inappropriate, suffer from a lack of support, and be over-generalizations of a broad range of envi- ronmental types encountered on seamounts. Ultimately, for seamount science to progress, we need to challenge our conventional wisdom on these habitats and the extent to which all seamounts function in a similar manner. *Correspondence: Craig R.

If urbanisation is accompanied by a concomitant increase in shipping then this may also be a factor, i.e. increased propagule pressure of non-native species due to translocation beyond their native range via the hulls of ships and/or in ballast water. Singapore is potentially highly vulnerable to invasion by non-native marine species as its coastline comprises over 60% seawall and it is one of the world’s busiest ports. The aim of this study is to investigate the native, non-native, and cryptogenic molluscs found on Singapore’s seawalls.

  • Coralliophiline Diversity at Mid-Atlantic Seamounts (Neogastropoda, Muricidae, Coralliophilinae)
    BULLETIN OF MARINE SCIENCE, 79(1): 205–230, 2006 NEW TAXA PAPER CORALLIOPHILINE DIVERSITY AT MID ATLANTIC SEAMOUNTS NEOGASTROPODA, MURICIDAE, CORALLIOPHILINAE Marco Oliverio and Serge Gofas ABSTRACT Eleven species of the Coralliophilinae were identified on seamounts of the NE Atlantic and in the Azores. The species-level taxonomy is reviewed with empha- sis on the protoconch species-specific characters. The Meteor group of seamounts yielded six species (plus two unidentified), with 3–6 species found sympatrically. Babelomurex atlantidis is described as new, Coralliophila aedonia (Watson, 1886), Babelomurex sentix (Bayer, 1971) and B. dalli (Emerson and D’Attilio, 1963) are re- ported for the first time in the mid-North Atlantic. Species which were found either abundant (C. aedonia, B. sentix, B. atlantidis) or reproducing (B. dalli) are assumed to form established populations on the mid-Atlantic seamounts. In the Lusitanian group of seamounts only Gorringe yielded more than one species; all species are shared either with the European mainland or with the Canary Islands, and there is no evidence for established populations. The coralliophiline species found on the seamounts showed evidence of planktotrophic larval development; at least two are amphiatlantic, which illustrates the role of the seamounts as stepping stones in transoceanic dispersal. Some species are not known outside the seamounts, but this may be explained by the increased availability of bathyal hard bottoms rather than by limitations to dispersal. The Coralliophilinae include ca. 200 species of coral eating gastropods, distributed worldwide in tropical and temperate seas. Their placement within the family Muri- cidae, close to Rapaninae s.l. is strongly supported by molecular data (Oliverio and Mariottini, 2001a; Oliverio, Cervelli and Mariottini, 2002).

Vermeij; e-mail: [email protected] Downloaded from (Received 5 September 2013; accepted 10 February 2014) ABSTRACT The shells of many marine gastropods have ventrally directed serrations (serial projections) at the edge http://mollus.oxfordjournals.org/ of the adult outer lip. These poorly studied projections arise as extensions either of external spiral cords or of interspaces between cords. This paper describes taxonomic, phylogenetic, architectural and func- tional aspects of serrations. Cord-associated serrations occur in cerithiids, strombids, the personid Distorsio anus, ocenebrine muricids and some cancellariids. Interspace-associated serrations are phylo- genetically much more widespread, and occur in at least 16 family-level groups. The nature of serration may be taxonomically informative in some fissurellids, littorinids, strombids and costellariids, among other groups. Serrated outer lips occur only in gastropods in which the apex points more backward than upward, but the presence of serrations is not a necessary byproduct of the formation of spiral sculp- tural elements.

The stem group from which the Latrogastropoda originated lived during or shortly before Aptian/Albian time (100–125 Ma). Several groups of Latrogastropoda that lived at the time of deposition of the Campanian to Maastrichtian (65–83 Ma) Ripley Formation have no recognized living counterparts. These Late Cretaceous species include the Sarganoidea, with the families Sarganidae, Weeksiidae and Moreidae, which have a rounded and low protoconch with a large embryonic whorl.

    Zoological Journal of the Linnean Society, 2017, 180, 732–754. With 5 figures. The varix: evolution, distribution, and phylogenetic clumping of a repeated gastropod innovation NICOLE B. WEBSTER1* and GEERAT J. VERMEIJ2 1Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2E9 2Department of Earth and Planetary Sciences, University of California, Davis, CA 95616, USA Received 27 June 2016; revised 4 October 2016; accepted for publication 25 October 2016 A recurrent theme in evolution is the repeated, independent origin of broadly adaptive, architecturally and function- ally similar traits and structures. One such is the varix, a shell-sculpture innovation in gastropods. This periodic shell thickening functions mainly to defend the animal against shell crushing and peeling predators. Varices can be highly elaborate, forming broad wings or spines, and are often aligned in synchronous patterns. Here we define the different types of varices, explore their function and morphological variation, document the recent and fossil distri- bution of varicate taxa, and discuss emergent patterns of evolution. We conservatively found 41 separate origins of varices, which were concentrated in the more derived gastropod clades and generally arose since the mid-Mesozoic. Varices are more prevalent among marine, warm, and shallow waters, where predation is intense, on high-spired shells and in clades with collabral ribs. Diversification rates were correlated in a few cases with the presence of varices, especially in the Muricidae and Tonnoidea, but more than half of the origins are represented by three or fewer genera. Varices arose many times in many forms, but generally in a phylogenetically clumped manner (more frequently in particular higher taxa), a pattern common to many adaptations.
