Helgol Mar Res (2020) 74:2 https://doi.org/10.1186/s10152-020-0534-x Helgoland Marine Research ORIGINAL ARTICLE Open Access Age and growth of Glycymeris longior (Sowerby, 1832) clam at the southern edge of its distribution (Argentine Sea) Lucas H. Gimenez1,2†, María del Socorro Doldan1,3,4*† , Paula C. Zaidman1,3,4 and Enrique M. Morsan1,3 Abstract Even though Glycymeris longior is a clam widely distributed in the SW Atlantic Ocean, little is known about its biology and life history. The present study assessed the periodicity of the internal growth increments of G. longior using thin shell sections. Each internal growth increment was composed of two alternating bands: a translucent band (light- coloured when viewed with transmitted light) and an opaque band (dark-coloured). Annual formation for each pair of bands was demonstrated. The formation of the annual growth increments was synchronous among individuals. Growth was determined from live clams collected at El Sótano, Argentine Sea (age range 29 to 69 years). Accord- ing to the growth model, G. longior grows fast during the frst 5 years of life and then growth= becomes slower in later years; individuals reached 50% and 90% of maximum size at 5 and 13 years of age, respectively. High variability was found in shell height for the frst 10 years: diferences up to 5–7 mm among individuals were registered for the frst 2 years of age, and up to 11 mm between the ages of 3 and 9 years. The growth performance index phi-prime (φ′) and the index of growth performance (P) of G.

Abstract Background: Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long attracted interest given its implications for understanding the evolution of endosymbiosis. However, photosynthetic ability varies widely among sacoglossans; some species have no plastid retention while others survive for months solely on photosynthesis. We present a molecular phylogenetic hypothesis for the Sacoglossa and a survey of kleptoplasty from representatives of all major clades. We sought to quantify variation in photosynthetic ability among lineages, identify phylogenetic origins of plastid retention, and assess whether kleptoplasty was a key character in the radiation of the Sacoglossa.

Coles2 1 Department of Biology, University of New Mexico, Albuquerque, New Mexico 87131, U.S.A. 2 Mollusca Section, Department of Biodiversity, National Museum of Wales, Cathays Park, Cardiff CF10 3NP, U.K. Corresponding author: [email protected] Abstract: The Pupillidae form an important component of eastern North American land snail biodiversity, representing approx. 12% of the entire fauna, 25-75% of all species and individuals at regional scales, at least 30% of the species diversity, and 33% of individuals within any given site. In some regions pupillids represent 80-100% of total molluscan diversity within sites, notably in taiga, tundra, and the base-poor pine savannas and pocosins of the southeastern coastal plain. Adequate documentation of North American land snail biodiversity thus requires investigators to effi ciently collect and accurately identify individuals of this group. This paper presents a set of annotated keys to the 65 species in this family known to occur in North America east of the Rocky Mountains. The distinguishing taxonomic features, updated county-scale range maps, and ecological conditions favored by each are presented in hopes of stimulating future research in this important group. Key words: microsnail, biodiversity, ecology, biogeography, taxonomy For the last dozen years, our interests in terrestrial Adequate documentation of this diversity thus requires gastropod biodiversity have lead us individually and investigators to effi ciently collect and accurately identify collectively to observe molluscan communities over most of individuals from this family.

    Systematics of the North and Central American Aquatic Snail Genus Tryonia (Rissooidea: Hydrobiidae) ROBERT HERSF LER m SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 612 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.

Box 6740 Perrytown, Arkansas 71801 April 2008 EXECUTIVE SUMMARY There are currently 13 species of Fusconaia and 32 species of Pleurobema recognized in the United States and Canada. Twelve species of Pleurobema and two species of Fusconaia are listed as Threatened or Endangered. There are 75 recognized species of Unionidae in Arkansas; however this number may be much higher due to the presence of cryptic species, many which may reside within the Fusconaia /Pleurobema complex. Currently, three species of Fusconaia and three species of Pleurobema are recognized from Arkansas. The true conservation status of species within these genera cannot be determined until the taxonomic identity of populations is confirmed. The purpose of this study was to begin preliminary analysis of the species composition of Fusconaia and Pleurobema in Arkansas and to determine the phylogeographic relationships within these genera through mitochondrial DNA sequencing and conchological analysis.

  • Armed Snaggletooth Gastrocopta Armifera ILLINOIS RANGE
    armed snaggletooth Gastrocopta armifera Kingdom: Animalia FEATURES Phylum: Mollusca One-eighth inch is the largest shell dimension of this species. Class: Gastropoda Snails have a complex system of organs. The mouth contains Order: a radula, a flexible, ribbonlike structure lined with rows of teeth, used to scrape food. On the head are tentacles. Most Family: Vertiginidae snails in Illinois have an eye at the tip of each upper tentacle. ILLINOIS STATUS A snail’s shell develops in the egg along with the rest of its body and continues to grow until the snail reaches sexual common, native maturity. The shell is formed by deposits of calcium laid down by the mantle. As the shell grows in its coiled shape, whorls are added. A snail cannot leave its shell. It has a strong muscle inside that is firmly attached to the shell. Snail shells grow in a variety of shapes. Shell shape, number and type of whorls and shell ornamentation, such as ribs or hairs, aid in identification of species. Snail shells may persist long after the snail has died and often can be used to identify species. The shell of this snail has projections, called teeth or denticles, in its aperture that help protect its soft body from being eaten by insect predators. BEHAVIORS Snails need to seek sheltered places to live, eat and rest. They prefer to live in moist areas and are commonly found under logs, loose bark or coarse woody debris, and in leaf litter on the forest floor. In general, snail populations are greatest in areas that have high soil calcium levels.

  • ABSTRACT Title of Dissertation: PATTERNS IN
    ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.

The Old Woman Creek National Estuarine Research Reserve provided housing and some equipment for local surveys while research support was provided by a Research Experiences for Undergraduates award from NSF (DBI 0243878) to B. Michael Walton, by an NOAA fellowship (NA07NOS4200018), and by an EFFRD award from Cleveland State University. Numerous students were instrumental in different aspects of the surveys: Mark Lyons, Trevor Prescott, Erin Steiner, Cal Borden, Louie Rundo, and John Hook. Specimens were collected under Ohio Scientific Collecting Permits 194 (2006), 141 (2007), and 11-101 (2008). The Old Woman Creek National Estuarine Research Reserve in Ohio is part of the National Estuarine Research Reserve System (NERRS), established by section 315 of the Coastal Zone Management Act, as amended. Additional information on these preserves and programs is available from the Estuarine Reserves Division, Office for Coastal Management, National Oceanic and Atmospheric Administration, U. S.
