PETTIBONE SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 230 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti- tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These pub- lications are distributed by mailing lists to libraries, laboratories, and other interested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available. S.

  • Identification Guide to the Planktonic Polychaete Larvae Around the Island of Helgoland (German Bight)
    HELGOL.~NDER MEERESUNTERSUCHUNGEN Helgol/inder Meeresunters. 48, 1-58 (1994) Identification guide to the planktonic polychaete larvae around the island of Helgoland (German Bight) S. Plate* & E. Husemann* * Biologische Anstalt Helgoland (Meeresstation); D-27483 Helgoland, Federal Republic of Germany ABSTRACT: The purpose of this work is to provide the means of identifying the planktonic larvae of the polychaete species appearing in the plankton around the island of Helgoland (North Sea). During a three-year survey in this area, the larvae of 54 species out of 24 families belonging to the orders Orbiniida, Spionida, Capitelhda, Phyllodocida, Oweniida, Terebelhda, Sabelhda and the former Archiannelida have been recorded. Illustrated keys to the families, genera and species are presented. To facilitate the identification, additional descriptions and information about the seasonal appearance of the species are given. INTRODUCTION More than 13 000 species of polychaetous annelids take part in the marine benthos communities worldwide. Their distribution, species composition and population density are monitored within various benthos surveys. For the North Sea, especially the German Bight and the Wadden Sea, much information about the benthic polychaete fauna is available (Caspers, 1950; Stripp, 1969; DSrjes, 1977; Rachor & Gerlach, 1978; Gillandt, 1979; Salzwedel et al., 1985; Rachor, 1990; Bosselmann, 1991; Kr6ncke, 1991). In contrast, the holoplanktonic polychaete species and the meroplanktonic polychaete larvae, which are only part of the plankton during a more or less expanded phase of their ontogenesis, have never received much attention. Meroplanktonic polychaete larvae are seldomly recorded during studies monitoring the North Sea plankton (Smidt, 1951; Giere, 1968; Fransz, 1981; Bosselmann, 1989; Belgrano et al., 1990).

  • The Swimming Response of the Sacconereis Stage of Autolytus Varies to Changes in Hydrostatic Pressure
    AN ABSTRACT OF THE THESIS OF RANDALL WILLIAM SMITH for the MASTER OF ARTS (Name) (Degree) ZOOLOGY presented on m AY 9 1969 (Major) (Date) Title:THE SWIMMING RESPONSE OF THE SACCONEREIS STAGE OF AUTOLYTUS VARIUS TO CHANGES IN HYDROSTATIC PRESSURE Abstract approved: Redacted for Privacy Dr. Ivan Pratt The syllid polychaete Autolytus varius reproduces in the spring and early summer in Yaquina Bay, Oregon.The fertilized female epitokes, or Sacconereis, carry the developing eggs and larvae in a ventral sac until the larvae are ready to be released; incubation lasts 14 to 18 days in the laboratory.The effects of a small increase in hydrostatic pressure on the activity of Sacconereis were tested. When placed in a pressure vessel, these epitokes responded to in- creases of 0.39 Bar by orienting dorsally and swimming upward, and by increasing their swimming rate,Peak activity occurred in the first minute after a pressure stimulus.Following this, there was a period of accommodation until the epitokesreturned close to their normal level of activity; the period of accomodation lasted around 11 minutes, When the pressure was released, the worms either slowed their swimming rate, or they coiled and sank rapidly to the bottom of the vessel. Decerebrate Sacconereis of A. varius did not respond to pressure stimuli.The Sacconereis of A. magnus and A. prismaticus, and the Polybostrichus of A. prismaticus demonstrated swimming responses similar to A. varius Sacconereis. Three other species of polychaetes did not respond to pressure changes.The hydrostatic pressure response is possibly an adapta- tion of a planktonic stage of a normally benthic animal.

Smale (Marine Biological Association of the UK) Secondary Supervisors: Professor Stephen J. Hawkins (Marine Biological Association of the UK, University of Southampton), Dr Pippa Moore (Aberystwyth University) i UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences Doctor of Philosophy THE INFLUENCE OF OCEAN WARMING ON THE PROVISION OF BIOGENIC HABITAT BY KELP SPECIES by Harry Andrew Teagle Kelp forests represent some of the most productive and diverse habitats on Earth, and play a critical role in structuring nearshore temperate and subpolar environments. They have an important role in nutrient cycling, energy capture and transfer, and offer biogenic coastal defence. Kelps also provide extensive substrata for colonising organisms, ameliorate conditions for understorey assemblages, and generate three-dimensional habitat structure for a vast array of marine plants and animals, including a number of ecologically and commercially important species. This thesis aimed to describe the role of temperature on the functioning of kelp forests as biogenic habitat formers, predominantly via the substitution of cold water kelp species by warm water kelp species, or through the reduction in density of dominant habitat forming kelp due to predicted increases in seawater temperature. The work comprised three main components; (1) a broad scale study into the environmental drivers (including sea water temperature) of variability in holdfast assemblages of the dominant habitat forming kelp in the UK, Laminaria hyperborea, (2) a comparison of the warm water kelp Laminaria ochroleuca and the cold water kelp L.

The traditionally recognized classes were Polychaeta, Oligochaeta and Hirudinea. The latter two are now viewed as the taxon Clitellata, since recognizing Hirudinea with class rank renders Oligochaeta paraphyletic. Polychaeta appears to contain Clitellata, and so may be synonymous with Annelida. Current consensus would place previously rec- ognized phyla such as Echiura, Pogonophora, Sipuncula and Vestimentifera as annelids, though relationships among these and the various other annelid lineages are still unresolved. Key words: Polychaeta, Oligochaeta, Clitellata, Echiura, Pogonophora, Vestimentifera, Sipuncula, phylogeny, review Introduction Annelida is a group commonly referred to as segmented worms, found worldwide in terrestrial, freshwater and marine habitats. The first annelids were formally named by Linnaeus, including well-known forms such as the earthworm Lumbricus terrestris Linnaeus, 1758, the medicinal leech Hirudo medicinalis Linnaeus, 1758, and the sea-mouse Aphrodite aculeata Linnaeus, 1758.

A review of the occurrence and ecology of dense populations of Ditrupa arietina (Polychaeta: Serpulidae). Memoirs of Museum Victoria 71: 85–95. Dense populations of the free-living serpulid Ditrupa arietina were first recorded to the west and north of the Shetland Isles in the 1920s and have since been reported from the Celtic and North Seas, the Armorican shelf, the Mediterranean and the Azores. These dense populations (of many thousands per square metre) numerically dominate the benthic fauna, and the tubes provide sites of attachment for a range of other species. Vacated tubes are also occupied by other animals, and tube fragments can contribute significantly to biogenic carbonate sediments, both Recent and fossil. Dense Ditrupa populations have been the subject of detailed autecological research over the last 15 years, but in spite of the apparent ecological importance of the species, it is not reflected in the European Nature Information System (EUNIS) or other North-east (NE) Atlantic habitat classifications. This paper provides a synthesis of the environmental conditions where high densities of Ditrupa have been found, with new data from seabed samples and photos.

  • Polychaete Patterns from an Oceanic Island in the Eastern Central Atlantic: La Gomera (Canary Archipelago)
    Cah. Biol. Mar. (2001) 42 : 275-287 Polychaete patterns from an oceanic island in the eastern Central Atlantic: La Gomera (Canary Archipelago) Salvador HERRANDO-PÉREZ1, Guillermo SAN MARTÍN2 and Jorge NÚÑEZ1 1Departamento de Biología Animal (Zoología), Universidad de La Laguna, 38206 La Laguna, Spain, fax number (34) 922 318311 E-mail: [email protected] and : [email protected] 2Departamento de Biología (Zoología), Universidad Autónoma de Madrid, 28049 Madrid, Spain, fax number (34) 91 3978344 E-mail : [email protected] Abstract: The polychaete macrofauna along the shallow sublittoral of La Gomera (Canary Islands, eastern Central Atlantic) was surveyed during the summer 1995 with a 0.01 m2 van Veen grab. Sampling resulted in a moderate number of specimens per sample unit, which influenced the assessment of α and β diversity. Diversity patterns followed sediment and hydrographic gradients between the north of the island (coarse sandy bottoms directly exposed to the open ocean), and the south (sheltered fine sandy bottoms). Of the 81 taxa recorded, two species were new to science, while a further 24 species were cited for the first time from the Canaries. Spionids (46% of faunal density), syllids (14 species) and onuphids were locally well represented and their distribution responded to life history features and sediment types. Polychaetes with a wide biogeographic range and relying on meroplanktonic phases, for dispersal, predominated. Factors controlling the access of polychaete populations to oceanic islands are discussed, including the role of major surface oceanic currents in the dispersion of larvae and reproductive adaptations of species.
