The adductor pectoral fin muscle in post-spawning females of the white croakerMicropogonias furnieri (Desmarest, 1823) is described from a morphological, histochemical and morphometric perspectives. A description of the morphological characteristics was conducted after dissections in different layers, down to the deep layer. Five muscles were found: superficial, medial, radial and deep adductors, and dorsal arrector. Their fibers were studied after applying histochemical techniques: succinic dehydrogenase (SDH) to reveal mitochondria, periodic acid-Schiff (PAS) for glycogen, Sudan black for lipids, myosin adenosinetriphosphatase (mATPase) to reveal the types of fibers, and modified mATPase to evidence the capillaries. Fiber diameters were measured and the number of capillaries was counted. Fiber subtypes named small, medium and large were found within red, pink and white fibers, the latter prevailing. Staining homogeneity was observed in white fibers after alkaline pre-incubations. The number of capillaries decreased from red to white fibers. Due to the prevalence of white fibers, the adductor muscle of the pectoral fins appears to be capable of rapid and discontinuous movements, which are important to body stabilization during subcarangiform swimming. The homogenous staining of white fibers observed in this research corresponds to the post-spawning gonad stage studied.

  • 15 International Symposium on Ostracoda
    Berliner paläobiologische Abhandlungen 1-160 6 Berlin 2005 15th International Symposium on Ostracoda In Memory of Friedrich-Franz Helmdach (1935-1994) Freie Universität Berlin September 12-15, 2005 Abstract Volume (edited by Rolf Kohring and Benjamin Sames) 2 ---------------------------------------------------------------------------------------------------------------------------------------- Preface The 15th International Symposium on Ostracoda takes place in Berlin in September 2005, hosted by the Institute of Geological Sciences of the Freie Universität Berlin. 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

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

VIAL and F. PATRICIO OJEDA* Departamento de Ecologfa,'Facultad de Ciencias Biol6gicas, Pontificia Universidad Catolica de Chile, Casilla 114-D, Santiago, Chile ABSTRACT Structural and functional restrictions hindering the development of efficient mechanism for cropping and ingestion of algal material could constitute an explanatory hypothesis for the observed low diversity of herbivorous fishes. In this study, the cephalic structures of the herbivorous kyphosid fish Girel/a laevifrons (Tschudi 1844) are described, in- cluding a functional analysis of its alimentary apparatus. This species can be characterized by having: (i) a great freedom of movement between the dentary and articular-angular, (ii) a double insertion of the muscle adductor mandibulae A1 in both faces of the maxilla, (iii) specialized teeth, long and flexible with a peculiar articular condyle at their an- terior base, (iv) a mobile articulation between ceratohyal and dorsal hypohyal, and (v) a well developed branchio- stegal system. A mechanism based on a mandibular manipulation associated with a slow suction of a large volume of water is proposed. This mechanism would allow the ingestion of large amounts of algae (as long stripes) in a continuous fashion. The combined activity of both an oral manipulation and buccal suction systems are possible by the existence of a decoupling of the anterior and posterior regions of the buccal cavity involving the jaw and the hyoid arch.

Breve definición del grupo y principales caracteres diagnósticos Según el criterio más extendido actualmente, y que aquí seguiremos, se considera a los ostrácodos como una clase (Cl. Ostracoda) del Subphylum Crustacea, perteneciente al Phylum Arthropoda. No obstante, existen autores que defienden su pertenencia, como subclase, a la clase Maxillopoda (que incluiría tam- bién a branquiuros, tantulocáridos, copépodos y cirrípedos, entre otros). Más allá de esta circunstancia, los ostrácodos pueden describirse como crustáceos de tamaño mediano a pequeño (desde los 0,2 a los 5 mm; con casos excepcionales que alcanzan los 3 cm), que poseen un ojo naupliar medial, con la segmen- tación corporal severamente reducida, entre cinco y ocho pares de apéndices y, como elemento más significativo, la presencia de un caparazón bivalvo. Aunque el caparazón contiene en sí mismo rasgos diagnósticos (tamaño, forma, ornamentación...) que ayudan a la correcta asignación taxonómica de los ostrácodos, su presencia—que obstaculiza la observación in vivo de muchos detalles diagnósticos del animal— y el pequeño tamaño de estos organismos obligan con frecuencia a la disección de los ejempla- res para su identificación, especialmente para la identificación a nivel específico.
