Growth of Pollicipes Pollicipes (Gmelin, 1790) (Cirripedia, Lepadomorpha) On the Sw Coast of Portugal
Authors: Cruz Teresa 
Published: April 2008

AbstractPollicipes pollicipes is widely used as food and is the subject of intensive fisheries in Portugal. Since November 1990 growth of this species was studied on the SW coast of Portugal. Two kinds of methods were used: (1) individual growth: the adjacent substrata were marked with polyester resin and the organisms were mapped and measured (Rostro-Carina length=RC) every month; 2) spatial variability of allometric growth: various biometrical measures were used for animals from different habitats; the relationship between these values and the organic weight were established. The results of these analyses suggest that there are spatial (due to tide and light related factors) and temporal differences (growth rates arc higher in spring and summer) in the growth of this pedunculate barnacle. In this study RC was the biometrical variable that best represented the linear growth of this species and we recommend its use for fishery control purposes.
Juvenile Morphology and Appearance of Sexual Appendages in Two Porcellanid Crabs, Petrolisthes Rufescens (Heller, 1861) and Pisidia Gordoni (Johnson, 1970) (Decapoda, Anomura, Porcellanidae)
Authors: Paul Ravindra , Sankolli K.N. , Shenoy Shakuntala 
Published: April 2008

Abstract
The porcellanid crabs in their larval phase show typical anomuran features but develop a crab-like form from megalopa through the juvenile instars. However, the adult species characters are not yet noticeable in the juvenile phase thus leading to confusion in identity both at specific or even at generic level. With attainment of the crab-like form, the reproductive appendages, like male pleopods, show a brachyuran pattern. In absence of external sexual dimorphism, sex determination is difficult in this group. Very little information is available as to how and when the sexual appendages start developing in Porccllanidae. With the purpose of tracing the development of the adult taxonomic characters and that of the reproductive appendages (and sex differentiation), the present paper describes the juvenile laboratory development of two porcellanid crabs, viz. Petrolisthes rufescens (Heller) up to instar III and Pisidia gordoni (Johnson) up to instar IV. Taxonomic features: In both the species the definitive adult features like those of the carapace front and its armature, the chelipeds and other pereiopods, the sternite of the third maxillipeds, etc., develop in the third instar. Sexual appendages: (a) In Petrolisthes rufescens the primary pleopods get totally reduced at least up to instar III and, therefore, the sexual appendages appear to be developing as a secondary series of pleopods, particularly in the female. (b) In Pisidia gordoni, at least in the male, differentiation starts from instar II onwards with the first pleopod modifying into a male appendage, while the remaining pleopods gradually become reduced.

Larval Development of the Spider Crab Acanthonyx Petiverii H. Milne Edwards, 1834 (Decapoda, Majidae) in the Laboratory
Authors: Hiyodo Célia Mary , Fransozo Adilson , Negreiros Fransozo Maria Lúcia 
Published: April 2008

Abstract
The larval development of Acanthonyx petiaerii H. M. Edwards, 1834, was studied in the laboratory through eggs hatched from ovigerous females collected in Ubatuba, state of São Paulo, Brazil. The rearings were carried out in a climatic room with constant temperature (25° ±1° C) and salinity (34,5‰). The larvae were maintained individually and the food consisted of Artemia nauplii. The larval development of A. petiverii consists of two zoeal stages and a megalopa. All the larval stages were drawn and described in detail. Tables include those presenting morphological characters that allow the identification of zoeae and megalopa of A. petiverii. A comparative study was realized with previously studied majid species that occur in southern and southeastern Brazil.
Restitution De Pseudorhombila Xanthiformis Garth, 1940, Pour Nanoplax Garthi Guinot, 1969 (Decapoda, Goneplacidae)
Authors: Hendrickx Michel E. 
Published: April 2008

AbstractThe recent collection of two females and onc male of Pseudorhombila xanthiformis Garth, 1940, in the Gulf of California, permits to complete the definition of this species previously known from female specimens only. P. xanthiformis was transferred to the genus Nanoplax Guinot, 1969, as N. garthi Guinot, 1969, nom. nov. A close examination of the sternum-abdomen organization and of the sexual pleopods of the male, and the comparison of this fresh material of P. xanthiformis, with P. quadridentata (Latreille, 1828), P. octodentata Rathbun, 1906, and P. guinotae Hernandez-Aguilera, 1982 on the one hand, and on the other hand with Nanoplax xanthiformis (A. Milne Edwards, 1880), the type-species of Nanoplax, lead us to the conclusion that Garth's species should be maintained in the genus Pseudorhombila A. Milne Edwards.

Caractères Biométriques De Penaeus Kerathurus (Forskål, 1775) Du Golfe De Gabès, Tunisie (Decapoda, Penaeidae)
Authors: Ben Mariem Sadok 
Published: April 2008

AbstractEight-hundred-and-twenty-five individuals of Penaeus kerathurus were obtained from the landings of shrimp trawlers in a programme from February 1991 to February 1992. These samples consisted of 479 females and 346 males. In each sample the smallest sized specimen was a male and the biggest a female. The mean size Lc (= carapace length) of females (38.8 mm) is significantly greater than the mean size of males (Lc = 32.5 mm). Allometric equations show that the increases in size of, e.g., telson, rostrum, height, total size or weight in relation to the carapace length (reference size) is nearly equal for the two sexes and is expressed for all characters (except height and weight) in both sexes by a negative allometry. Application of the equality test of the regression slope for male and female shows that the parallelism hypothesis is accepted for all the regressions established, except that of weight in relation to the total length where the difference is highly significant.
An Account of Our Knowledge of the Amphipod Fauna of the Aegean Sea
Authors: Stefanidou D. , Voultsiadou-Koukoura E. 
Published: April 2008

Abstract
During benthic surveys in the northern Aegean Sea, 188 amphipod species were found; 39 among these comprise new records for the amphipod fauna of the eastern Mediterranean Sea, 41 are reported for the first time from the Aegean Sea and 62 are new for the fauna of the northern Aegean Sea. A checklist of the amphipods known from the Aegean Sea up to the present is given (239 species), along with their distribution in certain Mediterranean areas. For the most interesting species found, information on their distribution and their habitat is given. The amphipod fauna of the above areas is estimated, on the basis of the relevant literature. Finally, the affinities among these areas using the coefficient of Czekanowski, along with the number of species common to each pair of areas, are estimated.
Zymogen Secreting Cells in the Hepatopancreatic Duct of Pagurus Bernhardus (Linnaeus, 1758) and Clibanarius Longitarsus (De Haan, 1849) (Anomura)
Authors: Erri Babu D. , Manjulatha C. 
Published: April 2008

Abstract
Histological and histochemical observations reveal that there are two clusters of acidic polysaccharide secreting glands at the opening of the mouth into the oesophagus in Pagurus bernhardus and Clibanarius longitarsus. Below these there are structurally similar glands in the connective tissue of the oesophagus. The epithelial cells lining the hepatopancreatic main duct show secretory activity and they secrete acidophilic granular secretions, which are chemically similar to vertebrate pancreatic zymogen granules. Electron microscopic studies reveal the presence of secretory cells in the hepatopancreatic duct and the synthesis of zymogens within these cells. The time of release of these granular secretions synchronizes with the release of the food material into the midgut.
A New Record of Clistocoeloma Sinense Shen, 1933, From Taiwan (Decapoda, Brachyura, Grapsidae, Sesarminae), With Notes On Its Distribution and Ecology
Authors: Hsueh Pan-Wen , Huang Jung-Fu 
Published: April 2008

AbstractThe poorly known sesarmine crab Clistocoeloma sinense Shen, 1933, previously known only from Zhejiang in China, is recorded from the western part of Taiwan for the first time. The species is compared with the closely related C. merguiense De Man, 1888, and the differences discussed and illustrated. Specimens and records from Taiwan previously ascribed to C. merguiense are almost certainly C. sinense instead. Notes on the ecology of C. sinense are also presented.
Locomotor Activity Patterns and Feeding Habits in the Prawn Palaemon Serratus (Pennant, 1777) (Decapoda, Palaemonidae) in the Alfacs Bay, Ebro Delta, Spain
Authors: Guerao G. , Ribera C. 
Published: April 2008

AbstractDiel activity rhythms of the prawn Palaemon serratus from Alfacs Bay, Ebro Delta, Spain, were studied under laboratory conditions by time-lapse video recording. The activity pattern showed endogenous rhythmicity of a circadian period with maximum activity at night. The feeding habits of P. serratus were studied using the frequency-of-occurrence method and the points method. The food of this species mainly consists of molluscs and crustaceans, and the remains of gastropods, amphipods, isopods, bivalves, mysids, copepods, and decapods were identified. The remaining items consisted of cnidarians, polychaetes, ophiuroids, plant material, sand, and unidentified organic debris. Results indicate that P. serratus is a predator of benthic invertebrates rather than a scavenger or detritus feeder. Diet composition changes with the size of the prawn.
Ongrowing of Juvenile Spiny Lobsters, Panulirus Argus (Latreille, 1804) (Decapoda, Palinuridae), in Portable Sea Enclosures
Authors: Lozano-Alvarez Enrique 
Published: April 2008

AbstractThe spiny lobster catch from Bahia de la Ascensión, a large bay on the central coast of the Mexican Caribbean, is composed mainly of young adults and large juveniles of Panulirus argus. The fishery in this bay is based on artificial shelters called "casitas". A substantial part of the lobsters found beneath the casitas is of sublegal size (minimum size limit ~ 74 mm carapace length, CL). The possibility of ongrowing sublegal juveniles in portable sea enclosures to maximize the harvestable biomass was explored. The enclosures (3 x 3 x 1 m) were installed in shallow depths in the bay. Juveniles taken from nearby casitas were introduced in the enclosures and kept for different periods. Lobsters were fed with live molluscs and fish remains and were provided with suitable shelters. Experiments were conducted in two stages, in 1992 and 1993. Growth in size (CL) and in harvestable biomass (weight of legal-size lobsters) was examined. Maximum growth rates, lower percentages of mortality, and higher increases in harvestable biomass of lobsters were obtained after about 45 days. Confinement periods longer than 45 days resulted in reduced growth and higher mortality. Observations on lobster behaviour showed an increase in aggressive encounters and dominance displays from the third week of captivity onwards, which could be the main cause for the increase in mortality. The alternative of ongrowing sublegal juveniles for short periods (45 days), in conjuction with the casita system, could help increase the unit value of the catch.
Notes On the Taxonomy and Ecology of Aliaporcellana Telestophila (Johnson, 1958) (Decapoda, Anomura, Porcellanidae), a Crab Commensal On the Gorgonian Solenocaulon

AbstractDiacyclops humphreysi n. sp. is described from the Cape Range karst area, North-west Cape Peninsula, Western Australia. The new species fits the Diacyclops crassicaudis-complex (Reid, 1992), being close to D. longifurcus Shen & Sung, 1963, from China and D. alticola Kiefer, 1935, from India. The Diacyclops crassicaudis-complex is for the first time recorded in Australia.
Biochemical and Morphological Evidence for a New Species of River Crab Potamonautes Parvispina Sp. Nov. (Brachyura, Potamonautidae)
Authors: Stewart Barbara A. 
Published: April 2008

AbstractPotamonautid river crabs were collected from four sites along the Olifants River in the Western Cape, South Africa in order to determine morphological and genetic differentiation among these populations. Two distinct forms were identified, and fixed allele differences at some allozyme loci between sympatric populations of the two forms confirmed that they were reproductively isolated. It was concluded that these forms represent two species, one of which was previously unknown, and is described in this paper as Potamonautes parvispina sp. nov.

Authors: Paggi Juan Cesar 
Published: April 2008

AbstractMoina macrocopa hitherto unrecorded from the Neotropical Region is reported from Corrientes, northern Argentina. The features exhibited by the specimens found, which are described and illustrated, differ from that of M. m. americana, distributed in North America, and agree with those of the typical form. This apparent discrepancy and the probable introduction from the Old World are discussed. A key to the species of Moina occurring in South America is presented.
Phänomenologische Philosophie Oder Phänomenologische Psychologie?
Authors: Streiffeler Friedhelm 
Published: April 2008

AbstractThe first question raised in this article concerns the central points of Husserl's phenomenological psychology. They consist essentially of the following: (1) a re-questioning (going back) of the types of objects encountered to their mode of being experienced, and (2) an emphasis on the non-empirical (eidetic) character of this type of psychology. A criticism then follows that Husserl's analyses are too general; they are more ontologically than psychologically interesting. It is further criticized that Husserl's phenomenological psychology is primarily oriented toward the problems of gnosology and not so much at the problems of the everyday behavior of man. Nevertheless, the critique of Husserl affirms that phenomenological psychology is important for theoretical psychology insofar as Husserl very clearly develops the principles of concept-formation of psychology as a science. If phenomenological psychology is to be concrete and applicable to psychology, one must ask which are the concrete types of objects from which one has to go back to consciousness. These types of objects have been identified as work-tasks. This conception of phenomenological psychology accords with its eidetical character since the individual mode of performance of a work-task is in general largely irrelevant. To prove this conception from another viewpoint, the analysis of some French phenomenologists were scrutinized. First of all, it was shown how Politzer, one of the first French phenomenolo
Suggestions for an Existential-Phenomenological Understanding of Erikson's Concept of Basic Trust
Authors: Knowles Richard T. 
Published: April 2008

AbstractThis article is meant to be suggestive, not thorough, in the themes presented. It is suggestive of the ways in which an existential-phenomenological approach may contribute to an understanding of a fundamental therapeutic and lived issue. Beginning with a very brief description of what is experienced as fundamental in therapy, the ground on which all other issues depend, the developmental framework of Erikson was consulted since it was assumed that therapy was a reflection of life. The most fundamental issue for Erikson was the crisis of basic trust versus basic mistrust. Trust was understood and revealed by him in terms of bodily trust, ego predictability and its social aspects. Using Heidegger's Care Structure as a framework, the absence of the existential, future-oriented characteristic of trust became apparent and the contribution of a phenomenological approach became visible. In using Erikson's word "hope" for this characteristic, it became apparent that not only was the future characteristic added but that within it the bodily and ego aspects could be integrated. Some phenomenological research was referred to which demonstrated that this integration was a fuller and more accurate reflection of human experience than the more specialized psychoanalytic understanding of Erikson. Marcel's description of hope was then consulted for a further understanding of this characteristic and finally the fundamental issue in therapy was identified as a crisis of hope. We use the word hope often in our daily experience. What this article points to as a research topic which would be central to therapy and to the lived world is what we mean when we say, "I hope." The structure of the experience of hoping would reveal much of what is central to both the world of therapy and the lived world.
La Naissance De L'Espace Familial
Authors: Mook Bep , Bernabé Jean 
Published: April 2008

AbstractThis article is the result of a theoretical analysis of a consultation family therapy interview conducted by the well-known family therapist, Dr. S. Minuchin. In the interview, Minuchin effectively challenges the family's structure and the individual members' presenting identities and social roles. Through his successful use of metaphor and techniques like confrontation, enactment and confirmation, he leads the family members out of their confinement toward interaction. Based on a phenomenologically oriented analysis, the authors propose a theoretical formulation to account for the interpersonal space created during the therapeutic process. The directing question they address is: if every member of the family is confined to and legitimates his own conception of himself and his circumstances, how can mutually influencing relations be evoked? A main hypothesis is posed: the therapist faced with conflictual relationships effects consecutive synthesis which allow movement toward desired and alternative behaviors and toward the integration of each member into the family. Initially, the presenting behaviors are of a repetitive and unidimensional nature. The therapist proceeds to unlock these states mainly by using metaphors which point towards actual behaviors and desired alternatives. He thus opens a second dimension by presenting means which make reflection possible and heightens differentiation of self. Subsequently, the family members are led toward the formation of a positive and shared identity confirmed and affectively supported by the therapist. This process results in a third dimension where family members manifest personal reflective awareness of different ways of relating to each other. Integration of the individuals into a new family matrix becomes possible.
An Empirical Validation of Schopenhauer's Theory of Music Through Analysis of Listeners' Experiences of Mahler's Ninth Symphony
Authors: Osborne John W. , Kennedy Lillian 
Published: April 2008

AbstractIn the end, even the creative achievements of Shakespeare and Bach must be eradicated by death and nothingness, when the earth is burnt up in the sun. But the temporality of human existence and meaning does not invalidate the quest for meaning-for even that future universe, as dead as it must be will have some meaning, in that it contains the artifacts, even in ashes, of the sometime existence of human life and consciousness. We HAVE BEEN. It was towards this vision that Mahler strove (Holbrook, 1975, p. 29).
What Is Guilt?
Authors: Brooke Roger 
Published: April 2008

AbstractThis summary is offered as a psychological definition of being-guilty. Guilt is lived pre-reflectively in a context of real or imaginary accusatory others, and is constituted as a person accepts responsibility for damaged world-relationships whose meanings constitute shared and personally appropriated values. The contradiction between valued and damaged world-relationships is lived existentially as a rupture between revealed and hidden modalities, in which an appearance of harmony and integrity is maintained by concealing both the hidden, damaged world-relationships to which the person feels guiltily indebted, and the fact of the existential rupture. Guilt's mood is constituted as feelings, not necessarily clearly articulate, of lack of self-acceptance. Guilt is resolved as, and to the extent that, the existential rupture is closed, and the person is able to be fully and unambiguously present in his openness to the world.
