India 4Veer Wajekar Arts, Science & Commerce College, Phunde, Uran, Dist. – Raigad, Navi Mumbai, (M.S.) India Abstract Diversity of macrobenthos from Panvel creek remain poorly known. Here, the species composition and abundance of macrobenthos is explored from June 2018 to May 2019 to assess the ecological status of the creek. 18 species of macrobenthic fauna consisting of 14 genera, 12 families, 06 orders and 05 classes were recorded. The most abundant taxa were polychaetes, crustaceans, gastropods and pelecypods. Species belonging to Polynoidae, Cerithiidae, Potamididae, Neritidae and Trapezidae shows highest distribution and abundance. The creek is dominated by Perinereis cultrifera, Clypeomorus bifasciata, Potamides cingulatus, Nerita oryzarum and Neotrapezium sublaevigatum. N. sublaevigatum of the family Trapezidae from the class Bivalvia is recorded as an opportunistic taxa which exploits disturbed condition due to environmental stress. This study showed that at present though the creek is resourceful and supports the coastal marine life, is under considerable stress of anthropogenic inputs. Coastal environment of Panvel creek is deteriorating due to ongoing construction of Navi Mumbai International Airport and unplanned development activities. Present information could be helpful as a baseline data for further study of anthropogenic inputs on coastal ecosystem of Panvel creek. -

The need for laboratory-bred animals, eliminating the potential biohazard risks, for the ornamental aquarium trade and the growing demand for animal model systems for biomedical research reasons the work for optimising a successful breading protocol. The initial results demonstrate N. turrita as tough animals, surviving fluctuations in pH from 5 to 9, and shifts from a fresh-water environment to brackish (2 - 20 ppt), to sea-water (35 ppt) salinities. The females laid over 630 (at salinities 0, 2, 10 ppt and temperatures of 25 - 28oC) white oval 1 by 0.5 mm egg capsules continuously within 2 months after collecting semen from several males. Depositions of egg capsules are set apart 6 +/-3 days, and consist on average of 53 (range 3 to 192) egg capsules. Production of viable veligers was recorded under laboratory conditions.

The results obtained have removed any doubt about the sup- PHYLOGENY posed synonymies. In particular, it appears that N. stumpffi Boettger, 1890 and N. knorri (Récluz, INDO-PACIFIC 1841), previously considered as sub-species, are valid separate species different from N. pulli- gera. Indeed, these two taxa are sympatric, morphologically differentiable and genetically dis- tant by more than 11 % for the COI. The same applies to N. petitii (Récluz, 1841), N. canalis Sowerby, 1825, N. iris Mousson, 1849, N. asperulata (Récluz, 1843) and N. powisiana (Récluz, 1843), which have been confirmed as valid distinct species from N. pulligera. The Indo-Pacific distribution of N. stumpffi is proven, that of N. knorri is yet to be confirmed.

Observations on the Shells of Some Fresh-Water Neritid Gastropods from Hawaii and Guam1
Observations on the Shells of Some Fresh-Water Neritid Gastropods from Hawaii and Guam1 Geerat J. VERMEJJ Department of Biology, Yale University Abstract Observations on the fresh-water neritid prosobranch gastropods Neritina vespertina Sowerby 1849 and N. granosa Sowerby 1825 from Hawaii, and N. pul /igera conglobata von Martens 1879 and Septaria porce/lana (Linnaeus 1758) from Guam, have yielded a qualitative correlation between clinging ability of the animal and the degree of development of limpet-like shell characters. The hypothesis is put forth that the granular ornamentation on the shell of N. granosa, and possibly the presence of egg capsules on the shells of many fluviatile neritids (notably N. pu/ligera conglobata and S. porcellana) may create turbulence and minimize the effects of the strong current in which the animals live. Methods Shell dimensions were measured to the nearest tenth millimeter with Vernier calipers. Length was taken as the greatest distance from the apex to a point on the outer lip and usually coincides with the greatest linear dimension of the shell. Width is the greatest distance parallel to the outer edge of the parietal septum. Height is the greatest distance from a point on the dorsal surface to the plane of the opening of the shell measured perpendicular to the length and width dimensions. Attempts at quantitatively measuring the force by which the animal clings to the substratum and the resistance against shear were not successful, but the quali tative differences in these properties between the various species are striking. Names for the species discussed in this paper have been taken from Baker (1923), Kira (1962), and Rabe (1964), and have been confirmed and augmented by Drs. -

PRELIMINARY SURVEY and DIET ANALYSIS of JUVENILE FISHES of an ESTUARINE CREEK on ANDROS ISLAND, BAHAMAS Craig A. Layman and Bria
BULLETIN OF MARINE SCIENCE, 70(l): 199-210, 2002 NOTES PRELIMINARY SURVEY AND DIET ANALYSIS OF JUVENILE FISHES OF AN ESTUARINE CREEK ON ANDROS ISLAND, BAHAMAS CraigA. Layman and Brian R. Silliman Estuarine habitats are important nursery and feeding areas for a variety of fish and invertebrate species. Although numerous studies have investigated trophic linkages in temperate estuarine systems, few have empirically examined these relationships in tropi- cal and subtropical estuaries (Colton and Alevizon, 1983; Heck and Weinstein, 1989; Warburton and Blaber, 1992; Ley et al., 1994; Crabtree et al., 1998). Without knowledge of dietary relationships among organisms, community structure and population interac- tions are difficult to deduce. To this end, a food web approach can be valuable in the study of natural communities (Polis and Winemiller, 1996). Since many tropical and subtropical estuaries are numerically dominated by juvenile fishes (Arrivillaga and Baltz, 1999), the trophic role of these life stages is especially important. Juvenile fish utilization of mangrove and seagrass habitats has been docu- mented in the Caribbean (Robblee and Zieman, 1984; Stoner, 1986; Rooker and Dennis, 1991; Sedberry and Carter, 1993) and Florida (Thayer et al., 1987; Sheridan, 1997; Ley et al., 1999), although few studies have analyzed feeding habitats of the juvenile fishes in these areas (Heck and Weinstein, 1989; Hettler, 1989; Ley et al., 1994). To our knowl- edge, there have been no published studies of the distribution and diet of fishes in estua- rine creeks, and associated seagrass or mangrove areas, in the Bahamian Islands. The purpose of our study was twofold: (1) identify fish species utilizing five major habitat types (sandflat, mangrove, seagrass, rocky structure and artificial structure) of an estuarine creek on Andros Island, Bahamas, and (2) provide a preliminary diet analysis of common juvenile fishes. -

Edge Effect on a Neritina Virginea (Neritimorpha, Neritinidae
Edge effect on a Neritina virginea (Neritimorpha, Neritinidae) population in a black mangrove stand (Magnoliopsida, Avicenniaceae: Avicennia germinans) in the Southern Caribbean * VIVIANA AMORTEGUI-TORRES , ALEXANDER TABORDA-MARIN & JUAN F. BLANCO *University of Antioquia, Faculty of Natural Sciences, Institute of Biology. *Corresponding author: [email protected] Abstract. Mangroves in the Caribbean and particularly in the Urabá Gulf (Colombia) are strongly threatened by selective logging and conversion to pastures and croplands. Specifically, extensive Avicennia germinans- basin stands were converted to pastures during the twentieth century, thus exposing benthic fauna to an edge effect. We measured this effect on the population of a numerically dominant gastropod (Neritina virginea). Despite its resistance to natural disturbances, it is sensitive to extreme anthropogenic disturbances, and it would therefore be a good biological indicator of basin-mangrove conversion to pastures. Forest structure variables, soil texture, porewater properties and snail density and size were measured in quadrats placed in pastures, pasture-mangrove edges, and mangrove interiors. Snail abundance sharply decreased from the mangrove interior to the edge and then gradually towards the pastures. Individuals in the pasture were predominantly >10mm, and they frequently exhibited shell corrosion compared to individuals found in the interior. There were increases in soil temperature and pH (but oxygen) from interior to pasture consistent with canopy openness. The occurrence of the mangrove edges has led to a marked ecosystem-wide deterioration; however, N. virginea (abundance, size, shell corrosion) could be used as a reliable short to midterm indicator of microhabitat and microclimatic differences observed across mangrove-pasture edge. Key words: basin mangrove, pasture, gastropods, Urabá Gulf Resumen. -

ABSTRACT The family Neritidae has representatives in tropical and subtropical regions that occur in a variety of environments, and its known fossil record dates back to the late Cretaceous. However there have been few studies of molecular phylogeny in this family. We performed a phylogenetic reconstruction of the family Neritidae using the COI (722 bp) and the 16S rRNA (559 bp) regions of the mitochondrial genome. Neighbor-joining, maximum parsimony and Bayesian inference were performed. The best phylogenetic reconstruction was obtained using the COI region, and we consider it an appropriate marker for phylogenetic studies within the group. Consensus analysis (COI +16S rRNA) generally obtained the same tree topologies and confirmed that the genus Nerita is monophyletic. The consensus analysis using parsimony recovered a monophyletic group consisting of the genera Neritina , Septaria , Theodoxus , Puperita , and Clithon , while in the Bayesian analyses Theodoxus is separated from the other genera. -
ASPECTOS DA DINÂMICA POPULACIONAL DO GASTRÓPODE Neritina Virginea EM REGIÃO ESTUARINA DO RIO GRANDE DO NORTE, BRASIL*
ASPECTOS DA DINÂMICA POPULACIONAL DO GASTRÓPODE Neritina virginea EM REGIÃO ESTUARINA DO RIO GRANDE DO NORTE, BRASIL* Carlina Pinheiro CRUZ-NETA 1 e Gustavo Gonzaga HENRY-SILVA 2 RESUMO O gastrópode Neritina virginea (Linnaeus, 1758) é abundante no litoral nordestino e apesar da sua grande incidência, são poucos os estudos sobre aspectos relacionados à sua ecologia populacional. Neste contexto, verificou-se os padrões de distribuição, densidade e estrutura etária de N. virginea, relacionando-os com a salinidade e temperatura da água, granulometria do sedimento e biomassa vegetal de Ruppia maritima. Mensalmente, durante 13 meses (maio/2007 a maio/2008), foram realizadas coletas de moluscos, biomassa vegetal e sedimento em um transcecto de 180 m, perpendicular a linha da praia, na região estuarina do Rio Apodi/Mossoró. Foram obtidos os valores de temperatura e salinidade da água, além dos dados de pluviosidade. Neritina virginea apresentou um padrão agregado de distribuição espacial e densidade elevada quando comparada com a de outras espécies que habitam a região, como o bivalve Anomalocardia brasiliana. A maior densidade média de N. virginea foi de 7.310 indivíduos m-², em maio/2008, e a menor, em dezembro/2007, com média de 765 indivíduos m-². Os valores de densidade de N. virginea e salinidade apresentaram correlação negativa. No entanto, não foram constatadas correlações com a temperatura e a granulometria do sedimento. A densidade de N. virginea apresentou correlação positiva com a biomassa R. marítima, sendo mais abundante em locais com a presença deste vegetal. Nos meses de fevereiro a junho os indivíduos menores foram mais frequentes, podendo ser considerada a principal época de recrutamento desta espécie na região.
