ECOLOGICAL ENERGETICS of TROPICAL LIMPET Cellana Testudinaria (Linnaeus, 1758) LIVING on the ROCKY SHORE of OHOIWAIT, SOUTHEAST MOLUCCAS, INDONESIA
Journal of Coastal Deveolpment ISSN : 1410-5217 Volume 11, Number 2, February 2008 : 89-96 ECOLOGICAL ENERGETICS OF TROPICAL LIMPET Cellana testudinaria (Linnaeus, 1758) LIVING ON THE ROCKY SHORE OF OHOIWAIT, SOUTHEAST MOLUCCAS, INDONESIA Abraham Seumel Khouw Faculty of Fisheries and Marine Sciences, Pattimura University, Ambon Indonesia Received : November, 2, 2007 ; Accepted :January,4, 2008 ABSTRACT Study on ecological energetics of tropical limpet C. testudinaria has been carried out at approximately one year from October 2001 to September 2002. Population energy budgets estimated on the assumption of steady state conditions for C. testudinaria (Linnaeus, 1758) on the rocky shore of Ohoiwait, are presented. Large difference in population structure, and hence energetics, occurred at different localities along the rocky shore. Relatively high proportions (98 %) of the assimilated energy was lost via metabolism. Assimilation efficiency is 39 %, net growth efficiency is 1.8 %, and ecological efficiency 0.3 %. Production (P), energy flow (A) and total energy consumption (C) were expressed as functions of animal size, in order to facilitate gross estimations of the energy component for which data on size frequency and density are available.

Differential Algal Consumption by Three Species of <I>Fissurella</I
BULLETIN OF MARINE SCIENCE. 46(3): 735-748.1990 DIFFERENTIAL ALGAL CONSUMPTION BY THREE SPECIES OF FISSURELLA(MOLLUSCA:GASTROPODA)AT ISLA DE MARGARITA, VENEZUELA Craig J. Franz ABSTRACT Visual observations and gut analyses were used to determine types of food ingested by Fissurella nimbosa (Linnaeus, 1758), F. nodosa (Born, 1778), and F. barbadensis (Gmelin, 1791) at Isla de Margarita, Venezuela. Although these animals have a wide variety of algal sources from which to select and on which they appear to feed in an opportunistic fashion, specific food preferences exist. Fissurella nodosa prefers encrusting microalgae and diatoms; F. nimbosa ingests laminar sheets of predominantly brown algae; F. barbadensis feeds on a wide variety of algae but often selects coralline algae of which it ingests entire branches. In zones of overlap, it is hypothesized that competition for food among Fissurella species is minimal due to resource allocation through food preference. Laboratory experiments indicate that all three congeners can ingest a greater variety of algal types than they normally consume in the field. Differential food consumption indicates significantly more elaborate niche par- titioning among tropical intertidal Fissure/la than was previously known. Studies of comparative feeding among congeneric predators may provide insight into the manner by which organisms partition their environment. This partitioning may be achieved through spatial segregation, temporal allocation, or dietary pref- erence. In situations of spatial overlap and temporal feeding similarity, a unique opportunity exists to evaluate the way in which food preferences may help establish an individual's niche. In these circumstances, dietary studies of co-occurring congeners provides information concerning the partitioning of community food resources. -

The Renogenital System of Puncturella noachina L. By Anna Meyer (of the Zoological Museum, University of Kasan) with 10 text figures The study of the excretory and genital organs of the lower Diotocardia is of significant interest because one can expect in this organ system (in its composition of the heart and gills, but perhaps only as traces) the same parity and symmetry as must have theoretically been present in the Urgastropod. Haller believed he actually had discovered such a paired and symmetrical composition of the aforementioned organs in the extant species Puncturella (Cemoria) noachina L. in the Family Fissurellidae. However, later studies provoked considerable controversy among the admittedly few researchers who re-examined the renogenital system of this species and the controversy remained undecided. I therefore eagerly followed the suggestion of my father, Professor Eduard Meyer, to undertake a detailed study of the renogenital system of Puncturella and to examine the claims of the earlier workers. However, before I go to the account of my observations, I wish to briefly present the results of earlier studies. The first information on the renogenital system of Puncturella comes from v. Erlanger in 1892 in his work “On the Paired Nephridia of Prosobranchs”1, where he detected the existence of two nephridia and pointed out their strongly asymmetrical development. He observed that the right organ was extraordinarily well developed and extended almost through the entire body cavity of the animal, while the left kidney was greatly reduced. Both nephridia open through separate papilla into the mantle cavity to either side of the anus; the left papilla being weakly developed and having a far smaller opening. -
