The Histopathology of Antique Ark's Mantle (Anadara Antiquata) Post
The histopathology of antique ark’s mantle (Anadara antiquata) post-depuration with the shells’ filtration Nabila A. Putri, Laksmi Sulmartiwi, Kustiawan T. Pursetyo Faculty of Fisheries and Marine, Universitas Airlangga, 60115, Surabaya, Indonesia. Corresponding author: L. Sulmartiwi, [email protected] Abstract. Cockles are marine organisms which have the character of filter feeders so that heavy metals can be neutralized naturally through their shells. However, not all heavy metals can be neutralized, so depuration needs to be done. After depuration, histopathological analysis is needed to determine the condition of the soft tissue of the shells so that the disease can be diagnosed through structural changes that occur in the organs that are the main target of pollutants. This study aims to determine the histopathology of antique ark’s mantle (Anadara antiquata) after post-depuration with the filtration of the cockles’ shells. This research method applies an experimental method with scoring histological damage to antique ark’s mantle that ranges from 0 to 3, depending on the level and extent of the changes that occur. After that, the distribution of normal and non-homogeneous data was obtained, and then the Kruskal-Wallis non-parametric test was conducted. The main parameter is the histopathology of the antique ark’s mantle. Supporting parameters include water quality, namely temperature, dissolved oxygen (DO), nitrate, nitrite, ammonia, salinity, levels of heavy metals Pb and Cd, total suspended solid (TSS) and total dissolved solid (TDS). The results of the Kruskal-Wallis statistical analysis shows no significant difference between treatments P0 (Control), P1 (Filter 25%), P2 (Filter 50%), P3 (Filter 75%), and P4 (Filter 100%). -
Response to Oxygen Deficiency (Depletion): Bivalve Assemblages As an Indicator of Ecosystem Instability in the Northern Adriatic Sea

This paper shows that Bivalve assemblages could serve as excellent indicators of disturbance and ecosystem instability. The goal of this study was to compare two sets of data in order to determine the differences between two different periods belonging to Bivalve assemblage in the muddy detritic bottom of the northern Adriatic Sea in the post-anoxic period during December 1989, 1990, 1991 and quite a while later, during 2003, 2004 and 2005. Abundances of some indicator species such as Corbula gibba, Modiolarca subpicta, and Timoclea ovata were detected during the post-anoxic period. Recruitment in the quality of Bivalve assemblages was proved by the ecologic and biotic indexes during 2003, 2004 and 2005, during a period of relatively stable ecological conditions. Fluctuation in Bivalve diversity due to the ecological quality of the marine ecosystem in the eastern part of the northern Adriatic Sea is also discussed. Key words: hypoxia; Bivalve assemblages; indicator species; soft bottoms; northern Adriatic Sea Introduction Recent reviews and summaries have provided good introductions on how hypoxia and anoxia came to be such a large and serious problem in the aquatic ecosystem (Gray et al. -

Paleontology and Sedimentology of Middle Eocene Rocks in Lago Argentino Area, Santa Cruz Province, Argentina
AMEGHINIANA (Rev. Asoc. Paleontol. Argent.) - 46 (1): 27-47. Buenos Aires, 30-04-2009 ISSN 0002-7014 Paleontology and sedimentology of Middle Eocene rocks in Lago Argentino area, Santa Cruz Province, Argentina Silvio CASADÍO1,2, Miguel GRIFFIN1,2, Sergio MARENSSI3,2, Laura NET4, Ana PARRAS1,2, Martín RODRÍGUEZ RAISING5,2 and Sergio SANTILLANA3 Abstract. Sedimentological and paleontological study of the Man Aike Formation at the Estancia 25 de Mayo, SW of Santa Cruz Province, Argentina, represents the evolution of an incised valley from fluvial to marine environment during the late middle Eocene. At the base of the unit there is an unconformity that corresponds to fluvial channels which cut down into the underlying Maastrichtian sandstones of the Calafate Formation. The fauna of invertebrates (mostly molluscs) illustrated herein was collected from shell beds interpreted as tidal ravinement surfaces. The fauna includes terebratulid brachiopods, bivalves of the families Malletiidae, Mytilidae, Pinnidae, Ostreidae, Pectinidae, Carditidae, Crassatellidae, Lahillidae, Mactridae, Veneridae, and Hiatellidae, and gastropods of the families Trochidae and Calyptraeidae, and a member of Archaeogastropoda of uncertain affinities. The similarities of this fauna with that recorded in the Upper Member of the Río Turbio Formation, together with 87Sr/86Sr ages, sug- gest a late Middle Eocene age for the Man Aike Formation.

Argopecten Irradians*
MARINE ECOLOGY PROGRESS SERIES I Vol. 74: 47-59, 1991 Published July 18 Mar. Ecol. Prog. Ser. The eelgrass canopy: an above-bottom refuge from benthic predators for juvenile bay scallops Argopecten irradians* David G.Pohle, V. Monica Bricelj8*,Zaul Garcia-Esquivel Marine Sciences Research Center, State University of New York, Stony Brook, New York 11794-5000, USA ABSTRACT: Juvenile bay scallops Argopecten irradians commonly attach to shoots of eelgrass Zostera marina using byssal threads. Although this behavior has long been recognized, its adaptive value is poorly understood. This study examined (1) the size-specif~cnature of scallop attachment on eelgrass, and (2) the possible role of vertical attachment in providing refuge from benthic predators. Laboratory experiments using artificial eelgrass showed strong, inverse relationships between scallop size (over the range 6 to 20 mm) and several measures of attachment performance (percent attachment, rate of attachment, and height-above-bottom attained). Field experiments in which 10 to 15 mm scallops were tethered to natural eelgrass in Lake Montauk, Long Island, New York (USA), demonstrated a dramatic, highly significant enhancement of scallop survival at greater heights of attachment. Scallops tethered at 20 to 35 cm above bottom experienced > 59 O/O survival over 4 d, compared to < l1 O/O sunrival near the sediment surface. A similar pattern was observed in laboratory tethering experiments using trans- planted natural eelgrass and 3 crab predators common in mid-Atlantic embayments: Carcinus maenas, Libinia dubia, and Dyspanopeus sayi. The refuge value of vertical attachment was found, however, to be less with D. sayi than with the other predators tested, since individuals of ths species climbed eelgrass to feed on scallops in the upper canopy. -

New Report and Taxonomic Comparison of Anadara and Tegillarca Species of Arcidae (Bivalvia: Arcoidea) from Southern Coast of India
International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Index Copernicus Value (2013): 6.14 | Impact Factor (2013): 4.438 New Report and Taxonomic Comparison of Anadara and Tegillarca Species of Arcidae (Bivalvia: Arcoidea) from Southern Coast of India Souji.S1, Tresa Radhakrishnan2 Department of Aquatic Biology and Fisheries, University of Kerala, Thiruvananthapuram-695 581, Kariyavattom, Kerala, India Abstract: Arcacea family is economically important group of animals. Most of the species in this family are misplaced into invalid subgenera and Indian arcids are wanted a revision in systematic positon. In the case of Arcidae family; all of the species are treated under Anadara as main genera, however, some authors considered that the Tegillarca genus is only a sub genus of Arcidae family. Anadara is the commercially important genus of bivalves of Arcidae family. These two genera are confused by many taxonomists and some considered that the morphometric changes of Tegillarca are only the habitual adaptation. But the collected samples from the same habitat from the southern part of India is clearly demarked the distinction between Anadara species and Tegillarca species. In this paper the differences between these two genera are illustrated with the help of specimens from the same habitat and with the help of taxonomic literature of these genera. Species level classification was done based on the morphometric characters like peculiarities of (i) periostracum, (ii) cardinal area, (iii) umbo, (iv) adductor muscle scar and (v) pallial line. The specimens were collected from Neendakara, Vizhinjam and Kovalam along with the south west coast and Thiruchendur in Tamil Nadu, south east coast of India.
