Effects of Parasites on Marine Maniacs
EFFECTS OF PARASITES ON MARINE MANIACS JOSEPH R. GERACI and DAVID J. ST.AUBIN Department of Pathology Ontario Veterinary College University of Guefph Guelph, Ontario Canada INTRODUCTION Parasites of marine mammals have been the focus of numerous reports dealing with taxonomy, distribution and ecology (Defyamure, 1955). Descriptions of associated tissue damage are also available, with attempts to link severity of disease with morbidity and mortality of individuals and populations. This paper is not intended to duplicate that Iiterature. Instead we focus on those organisms which we perceive to be pathogenic, while tempering some of the more exaggerated int~~retations. We deal with life cycles by emphasizing unusual adap~t~ons of selected organisms, and have neces- sarily limited our selection of the literature to highlight that theme. For this discussion we address the parasites of cetaceans---baleen whales (mysticetes), and toothed whales, dolphins and porpoises (odon- tocetes): pinnipeds-true seals (phocidsf, fur seals and sea Iions (otariidsf and walruses (adobenids); sirenians~anatees and dugongs, and the djminutive sea otter. ECTOPARASITES We use the term “ectoparasite’” loosely, when referring to organisms ranging from algae to fish which somehow cling to the surface of a marine mammal, and whose mode of attachment, feeding behavior, and relationship with the host or transport animal are sufficiently obscure that the term parasite cannot be excluded. What is clear is that these organisms damage the integument in some way. For example: a whale entering the coid waters of the Antarctic can acquire a yelIow film over its body. Blue whales so discoiored are known as “sulfur bottoms”. -

Seasonal Circulation Over the Catalan Innershelf (Northwest
JOURNAL OF GEOPHYSICAL RESEARCH: OCEANS, VOL. 118, 1–14, doi:10.1002/jgrc.20403, 2013 Seasonal circulation over the Catalan inner-shelf (northwest Mediterranean Sea) Manel Grifoll,1,2 Alfredo L. Aretxabaleta,3 Josep L. Pelegrı,4 Manuel Espino,1,2 John C. Warner,3 and Agustın Sanchez-Arcilla1,2 Received 5 February 2013; revised 12 September 2013; accepted 18 September 2013. [1] This study characterizes the seasonal cycle of the Catalan inner-shelf circulation using observations and complementary numerical results. The relation between seasonal circulation and forcing mechanisms is explored through the depth-averaged momentum balance, for the period between May 2010 and April 2011, when velocity observations were partially available. The monthly-mean along-shelf flow is mainly controlled by the along- shelf pressure gradient and by surface and bottom stresses. During summer, fall, and winter, the along-shelf momentum balance is dominated by the barotropic pressure gradient and local winds. During spring, both wind stress and pressure gradient act in the same direction and are compensated by bottom stress. In the cross-shelf direction the dominant forces are in geostrophic balance, consistent with dynamic altimetry data. Citation: Grifoll, M., A. L. Aretxabaleta, J. L. Pelegrı, M. Espino, J. C.

Two fronts follow the contine ntal she lf break on the peninsular and Balcaric sides, separating the cen tral dense waters from the surround ing lighter wa ters of Atlantic and contincntal origins. One is mainly produced by strong salin ity grudients (Catllian front) and the other by temperature gradients (Ba learic front). Two currents are associated with these fronts : the southwest Catalan current and the northeast Balearic current. Strong vertical mesosçale motions have been observed on several occasions in the weakly strlltified central area. An interpretation of these mesoscale phenomena is proposcd in terms of cyclonic eddies generated by some kind of instability mechanism in the two frontal systems. Oceollol. ACla, 1988.

The Annual of Language & Politics and Politics of Identity, Vol. VI./2012 Reviewed journal ALPPI is published by Faculty of Social Sciences, Institute of Political Studies. www.alppi.eu Valencian Identity, Language and Language Policy Karel Höfer1 Abstract: The general aim of this paper is to analyze Valencian language policy and Valencian language itself. Specifically it means, whether there are certain specific features in the Valencia region that distinguish it from the other Spanish regions, including a specific regional identity, language and other attributes. This issue is examined from broader historical, institutional, identitical, linguistic and political angles. Particular emphasis is placed on the Spanish decentralization process and on the specifics of the Valencian history, identity, politics and language. Key words: Valencian community, Valencian region, Valencian identity, Valencian language, Valencian language policy, Spanish language policy Introduction The field of language policy is a rapidly expanding discipline of social sciences. It is an interdisciplinary field at the boundary of political science, sociology, ethnology and linguistics. Language policy, unlike many other disciplines of social science, allows the application of its findings, derived from research into practical policies, which increases both its usefulness and attractiveness. Language policy deserves more attention, because it is an important aspect of everyday life, which directly affects all individuals, and affects the future of entire communities. Language policy is closely linked with decentralization processes in many countries. Decentralization is accompanied with the processes of integration, at least in the European area. The integration process takes place for example in the field of economics and politics within the European Union or for example the Council of Europe. -

Jose Antonio Novais, Madrid, Spain ABSTRACT Samples from the Amposta Marino C2 well (Amposta oil field) have been investigated in order to understand the origin of fractures and porosity and to reconstruct the fluid flow history of the basin prior, during and after oil migration. Three main types of fracture systems and four types of calcite cements have been identified. Fracture types A and B are totally filled by calcite cement 1 (CC1) and 2 (CC2), respectively; fracture type A corresponds to pre-Alpine structures, while type B is attributed to fractures developed during the Alpine compression (late Eocene-early Oligocene). The oxygen, carbon and strontium isotope compositions of CC2 are close to those of the host-rock, suggesting a high degree of fluid-rock interaction, and therefore a relatively closed palaeohydro- geological system. Fracture type C, developed during the Neogene extension and enlarged by subaerial exposure, tend to be filled with reddish (CS3r) and greenish (CS3g) microspar calcite sediment and blocky calcite cement type 4 (CC4), and postdated by kaolinite, pyrite, barite and oil. -
