Ostracoda an Introduction.Pdf
The Ostracoda (from Wikipedia, 5/5/2009: http://en.wikipedia.org/wiki/Ostracod) Ostracoda is a class of the Crustacea, sometimes known as the seed shrimp because of their appearance. Ostracods are small crustaceans, typically around one mm in size, but varying between 0.2 to 30 mm, laterally compressed and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper, dorsal region of the body. Some 65,000 species (13,000 of which are extant taxa) have been identified, grouped into several orders. This group may not be monophyletic. Ostracod taxa are grouped into a Class based on gross morphology. Ecologically, marine ostracods can be part of the zooplankton or (most commonly) they are part of the benthos, living on or inside the upper layer of the sea floor. Many ostracods, especially the Podocopida, are also found in fresh water and some are known from humid continental forest soils. The body consists of a cephalon (head), separated from the thorax by a slight constriction. The segmentation is unclear. The abdomen is regressed or absent whereas the adult gonads are relatively large. There are 5–8 pairs of appendages. The branchial plates are responsible for oxygenation. The epidermal cells may also secrete calcium carbonate after the chitinous layer is formed, resulting in a chalk layer enveloped by chitin. This calcification is not equally pronounced in all orders. During every instar transition, the old carapace (chitinous and calcified) is rejected and a new, larger is formed and calcified. The outer lamella calcifies completely, while the inner lamella calcifies partially, with the rest remaining chitinous. -

This is the second time that the International Symposium on Ostracoda has been held in Germany, following the 5th International Symposium in Hamburg in 1974. The relative importance of Ostracodology - the science that studies Ostracoda - in Germany is further highlighted by well-known names such as G.W. Müller, Klie, Triebel and Helmdach, and others who stand for the long tradition of research on Ostracoda in Germany. During our symposium in Berlin more than 150 participants from 36 countries will meet to discuss all aspects of living and fossil Ostracoda. We hope that the scientific communities working on the biology and palaeontology of Ostracoda will benefit from interesting talks and inspiring discussions - in accordance with the symposium's theme: Ostracodology - linking bio- and geosciences We wish every participant a successful symposium and a pleasant stay in Berlin Berlin, July 27th 2005 Michael Schudack and Steffen Mischke CONTENT Schudack, M. and Mischke, S.: Preface -
Marine Invertebrates of Digha Coast and Some Recomendations on Their Conservation

Other workers, viz., Bairagi, Bhadra, Mukhopadhyaya, Misra, Reddy (1995); Subba Rao et. al., (1992, 1995); Talukdar et. al., (1996); Ramakrishna and Sarkar (1998); Sastry (1995, 1998) and Mitra et. al., (2002) also reported some marine invertebrates under different faunal groups from Hughly-Matla estuary, including Digha. But uptil recently there is no comprehensive updated list of marine invertebrates from Digha coast and adjoining areas. With the establishment of Marine Aquarium and Research Centre, Digha in the year 1990, opportunity was launched for undertaking an extensive exploration and studying seasonal changes that have been taken place on the coastal biodiversity in this area. Accordingly, the authors of the present work, started collecting the detailed faunal infonnation from Digha and adjoining coastal areas [Fig. 2 and 3]. During the study, it has transpired that exploitation of coastal resources has very abruptly increased in recent years. Several new fishing gears are employed, a number of new marine organisms are recognized as commercial fish and non fish resources. Also, the number of trawlers has increased to a large extent. The present paper based on the observations from 1990 to 2000 (including the current records upto January, 2002), is an uptodate database for the available species of marine invertebrates from this area. -

Eleven ostracod species were identified in the genera Cytherella Jones, Cytherelloidea Alexander, Eocytheropteron Alexander, Semicytherura Wagner, Paracosta Siddiqui, Buntonia Howe, Soudanella Apostolescu, Leguminocythereis Howe and, probably, Pataviella Liebau. The planktonic foraminifera are represented by the genera Guembelitria Cushman, Parvularugoglobigerina Hofker, Woodringina Loeblich and Tappan, Heterohelix Ehrenberg, Zeauvigerina Finlay, Muricohedbergella Huber and Leckie, and Praemurica Olsson, Hemleben, Berggren and Liu. The ostracods and foraminifera analyzed indicate an inner shelf paleoenvironment for the studied section. Blooms of Guembelitria spp., which indicate either shallow environments or upwelling zones, were also recorded reinforcing previous paleoenvironmental interpretations based on other fossil groups for this basin. -

CALIFORNIA MARINE FISH LANDINGS FOR 1972 LEO PINKAS Marine Resources Region 1.1. INTRODUCTION The protection, propagation, and wise utilization of California's living marine resources (established as common property by statute, Section 1600, Fish and Game Code) is dependent upon the welding of biological, environment- al, economic, and sociological factors. Fundamental to each of these factors, as well as the entire management pro- cess, are harvest records. The California Department of Fish and Game began gathering commercial fisheries land- ing data in 1916. Commercial fish catches were first published in 1929 for the years 1926 and 1927. This report, the 32nd in the landing series, is for the calendar year 1972. It summarizes commercial fishing activities in marine as well as fresh waters and includes the catches of the sportfishing partyboat fleet. Preliminary landing data are published annually in the circular series which also enumerates certain fishery products produced from the catch. -

Barnacle Paper.PUB
Proc. Isle Wight nat. Hist. archaeol. Soc . 24 : 42-56. BARNACLES (CRUSTACEA: CIRRIPEDIA) OF THE SOLENT & ISLE OF WIGHT Dr Roger J.H. Herbert & Erik Muxagata To coincide with the bicentenary of the birth of the naturalist Charles Darwin (1809-1889) a list of barnacles (Crustacea:Cirripedia) recorded from around the Solent and Isle of Wight coast is pre- sented, including notes on their distribution. Following the Beagle expedition, and prior to the publication of his seminal work Origin of Species in 1859, Darwin spent eight years studying bar- nacles. During this time he tested his developing ideas of natural selection and evolution through precise observation and systematic recording of anatomical variation. To this day, his monographs of living and fossil cirripedia (Darwin 1851a, 1851b, 1854a, 1854b) are still valuable reference works. Darwin visited the Isle of Wight on three occasions (P. Bingham, pers.com) however it is unlikely he carried out any field work on the shore. He does however describe fossil cirripedia from Eocene strata on the Isle of Wight (Darwin 1851b, 1854b) and presented specimens, that were supplied to him by other collectors, to the Natural History Museum (Appendix). Barnacles can be the most numerous of macrobenthic species on hard substrata. The acorn and stalked (pedunculate) barnacles have a familiar sessile adult stage that is preceded by a planktonic larval phase comprising of six naupliar stages, prior to the metamorphosis of a non-feeding cypris that eventually settles on suitable substrate (for reviews on barnacle biology see Rainbow 1984; Anderson, 1994). Additionally, the Rhizocephalans, an ectoparasitic group, are mainly recognis- able as barnacles by the external characteristics of their planktonic nauplii.
