Neverita Delessertiana
Zootaxa 1257: 1–25 (2006) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA 1257 Copyright © 2006 Magnolia Press ISSN 1175-5334 (online edition) Neverita delessertiana (Récluz in Chenu, 1843): a naticid species (Gastropoda: Caenogastropoda) distinct from Neverita duplicata (Say, 1822) based on molecular data, morphological characters, and geographical distribution THOMAS HÜLSKEN, MARINA CLEMMENSEN & MICHAEL HOLLMANN Thomas Hülsken, Ruhr University Bochum, Universitätsstrasse 150, D-44780 Bochum, Germany, tho- [email protected] Marina Clemmensen, Ruhr University Bochum, Universitätsstrasse 150, D-44780 Bochum, Germany Michael Hollmann, Ruhr University Bochum, Universitätsstrasse 150, D-44780 Bochum, Germany, [email protected] Abstract The members of the caenogastropod family Naticidae show highly conserved morphological characters, which in many cases complicate species separation. In such cases DNA sequence analysis may help to distinguish between species. In this work partial sequences from the small mitochondrial ribosomal RNA (16S rRNA) gene, the small nuclear ribosomal RNA (18S rRNA) gene, a short intron of the nuclear calmodulin (Cal) gene, and the mitochondrial cytochrome oxidase subunit I (COI) gene are shown to differ significantly between the genomes of what generally had been considered to be merely two morphological variants of the common Western Atlantic naticid Neverita duplicata (Say, 1822). Sequence differences between the two forms of Neverita duplicata are similar to differences between either of these two forms and the Eastern Pacific Neverita reclusiana (Deshayes, 1839), the Indopacific Neverita didyma (Röding, 1798), and the Mediterranean Neverita josephinia (Risso, 1826). The COI sequences divergence between the two forms of Neverita duplicata is in the range of the average COI sequences divergence reported for congeneric species of Mollusca (Hebert 2003). -

Gastropoda: Rissoidae) in the Lower Miocene of Valle Ceppi (Torino, NW Italy
Bollettino della Società Paleontologica Italiana, 48 (1), 2009, 51-57. Modena, 15 maggio 200951 Two new species of Rissoina (Gastropoda: Rissoidae) in the Lower Miocene of Valle Ceppi (Torino, NW Italy) Marta ZUNINO & Giulio PAVIA M. Zunino, Dipartimento di Scienze della Terra, Università degli Studi di Torino, Via Valperga Caluso 35, I-10125 Torino, Italy; [email protected] G. Pavia, Dipartimento di Scienze della Terra, Università degli Studi di Torino, Via Valperga Caluso 35, I-10125 Torino, Italy; [email protected] KEY WORDS - Rissoidae, Rissoina, Lower Miocene, Valle Ceppi, Torino Hills, Tertiary Piedmont Basin. ABSTRACT - Two new species of Rissoina from the Miocene of Torino Hills, Rissoina (R.) giuntellii and Rissoina (R.) sturanii, are described in this paper. Rissoina (R.) giuntellii n. sp. is frequent in the Lower Miocene deposits of Valle Ceppi and in coeval and more recent layers of Torino Hills; it is characterized by a small shell with convex whorls, the sculpture is composed by prominent axial ribs and cords visible at the base of the last whorl. Rissoina (R.) sturanii n. sp. is only known from the Valle Ceppi section; it is characterized by medium-sized shells with flat whorls and very fine axial and spiral ornamentation. Because of the reduced number of specimens and their state of conservation, scanning electron microscope photographs were used to study shell micro-architecture where possible. Comparison with the coeval Rissoininae known from the deposits of Paratethys, Aquitaine Basin and Loire Basin confirmed the election of Rissoina (R.) giuntellii n. sp. and Rissoina (R.) sturanii n. sp., currently known only in the Miocene deposits of the Tertiary Piedmont Basin. -

The Status of Mariculture in North China
The Status of Mariculture in North China Chang Yaqing1,Chen Jiaxin2 (1.Key Lab of Mariculture and Biotechnology.Dalian Fisheries University,Dalian, Liaoning, 116023, P.R China;2.Yellow Sea Fisheries Research Institute Chinese Academy of Fisheries Sciences, Qingdao, Shandong,266071, P.R China) Introduction China has a long history of mariculture production. The mariculture industry in China has obtained break through in the all artificial nursery and cultural technique of shrimps, mollusca and fishes of high commercial value since 1950s, which has advanced the development of mariculture industry. The first major development was seaweed culture during 1950s, prompted by breakthroughs in breeding technology. By the end of the 1970s, annual seaweed production reached 250,000 metric tons in dry weight ( approximately 1.5million tons of fresh seaweed ). Shrimp culture developed during the 1980s because of advances in hatchery technology and economic reform policies. Annual shrimp production reached 210,000 tons in 1992. Disease outbreaks since 1993, however, have reduced shrimp production by about two-thirds. Mariculture production increased steadily between 1954 and 1985, but has been exponential since 1986, mostly driven by molluscan culture. Molluscan 1 culture in China began to expand beyond the four traditional species: oyster,cockle,razor clam and ruditapes clam in the 1970s,Mussel culture was the first new industry to emerge ,followed by scallop aquaculture in 1980s. Abalone culture has become a major industry in 1990s. Traditional oyster and clam cultures have also advanced and expanded in recent years.Now more than 30 species of marine mollusks are cultured commercially in China. Because of the rapid development in recent years, molluscan culture has become the largest sector of the Chinese mariculture industry, accounting for 81% of the total production in weight. -

Spermatogenesis and Sperm Ultrastructure in the Land Slug Limax Flavus (Gastropoda, Pulmonata) from Egypt
Advances in Biological Research 7 (6): 253-265, 2013 ISSN 1992-0067 © IDOSI Publications, 2013 DOI: 10.5829/idosi.abr.2013.7.6.76164 Spermatogenesis and Sperm Ultrastructure in the Land Slug Limax flavus (Gastropoda, Pulmonata) from Egypt Irene Sameh Gamil Department of Zoology and Entomology, Faculty of Science, Helwan University, Cairo, Egypt Abstract: Spermatogenesis and sperm ultrastructure are examined and described for the first time in the garden slug Limax flavus (Gastropoda, Pulmonata, Stylommatophora) in Egypt. Spermatogonia show round nuclei with patchy heterochromatin. The primary spermatocytes are characterized by the presence of synaptonemal complexes. The secondary spermatocytes are reduced in size and contain less cytoplasm and clustered stacks of Golgian cisternae with small proacrosomal vesicles lying close to them. During spermiogenesis, electron-dense plaques develop at both the future anterior and posterior poles of the nuclear surface. These plaques determine the apparent antero-posterior axis of the spermatid, the distal plaque indicates the future anterior part of the cell and the basal one the posterior part where an abundant number of mitochondria are aggregated. The mature spermatozoon shows the characteristic sperm features: an acrosomal vesicle supported by an acrosomal pedestal; a helically keeled nucleus, a neck region and a complex elongate middle piece featuring paracrystalline and matrix layers sheathing the axoneme, coarse fibers and glycogen helices. Key words: Spermiogenesis Spermatozoa Hermaphrodite snail Mollusca Pulmonate INTRODUCTION study, a detailed description of spermatogenesis process till the formation of mature autospermatozoa The bulk of the land Gastropoda consists of is presented. Studies on the spermatozoa and Pulmonata including the most important order spermatogenesis have been used extensively to Stylommatophora which is one of the most diverse and explore taxonomic and phylogenetic relationships of economically significant groups of living molluscs [1]. -

Academic Editor: Kellie L. Tuck Received: 30 April 2015 / Accepted: 18 June 2015 / Published: 29 June 2015 Abstract: Peptides are important bioactive natural products which are present in many marine species. These marine peptides have high potential nutraceutical and medicinal values because of their broad spectra of bioactivities. Their antimicrobial, antiviral, antitumor, antioxidative, cardioprotective (antihypertensive, antiatherosclerotic and anticoagulant), immunomodulatory, analgesic, anxiolytic anti-diabetic, appetite suppressing and neuroprotective activities have attracted the attention of the pharmaceutical industry, which attempts to design them for use in the treatment or prevention of various diseases. Some marine peptides or their derivatives have high commercial values and had reached the pharmaceutical and nutraceutical markets. A large number of them are already in different phases of the clinical and preclinical pipeline. This review highlights the recent research in marine peptides and the trends and prospects for the future, with special emphasis on nutraceutical and pharmaceutical development into marketed products.

A Zooarchaeological Perspective on Late Bronze and Early Iron Age Animal Utilization at Kinet Höyük (Turkey)
Life on the Periphery, Life at the Crossroads: A Zooarchaeological Perspective on Late Bronze and Early Iron Age Animal Utilization at Kinet Höyük (Turkey). by Radovan Kabatiar A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Near and Middle Eastern Civilizations University of Toronto © Copyright by Radovan Kabatiar 2017 Life on the Periphery, Life at the Crossroads: A Zooarchaeological Perspective on Late Bronze and Early Iron Age Animal Utilization at Kinet Höyük (Turkey). Radovan Kabatiar Doctor of Philosophy Department of Near and Middle Eastern Civilizations University of Toronto 2017 Abstract This study examines faunal skeletal remains from Kinet Höyük, a small harbour site in the Plain of Issos in the northeast corner of the Mediterranean. The faunal material in this study covers the period of approximately six and a half centuries in the long history of the site, spanning from the Late Bronze Age I through Late Bronze Age II, when the site was under Hittite control, and ends with the Early Iron Age. It aims to contribute to the growing body of environmental studies helping to understand and reconstruct events that mark the collapse of Late Bronze Age polities, and the following era of transformation and formation of new political and geographical entities. Based on the analysis of nearly 35,000 animal bones, I argue that the local population continued occupation of the site and adjusted their subsistence strategies to the changing geopolitical, economic and climatic conditions, despite a decline observed toward the end of the Late Bronze Age, and that the modifications seen in animal husbandry and exploitation of wild fauna reflect a period of hardship, rather than influx of new settlers.
