Solitary forms ( =oozoids) are asexual and produce chains of aggregate sexual forms ( = blastozoids= gonozoids) by means of budding from a stolon. Asymmetrical aggregate forms are either dextral or sinistral according to the side of the stolon on which they developed. -3- A. Intestinal tract not forming a haU:-shaped "nucleus" ..............

    Henschke et al. Marine Biodiversity Records (2016) 9:21 DOI 10.1186/s41200-016-0023-8 MARINE RECORD Open Access An observation of two oceanic salp swarms in the Tasman Sea: Thetys vagina and Cyclosalpa affinis Natasha Henschke1,2,3*, Jason D. Everett1,2,3 and Iain M. Suthers1,2,3 Abstract Background: Large oceanic salps are rarely encountered. The highest recorded biomasses of the salps Thetys vagina (852 g WW m−3)andCyclosalpa affinis (1149 g WW m−3) were observed in the Tasman Sea during January 2009. Results: Due to their fast sinking rates the carcasses and faecal pellets of these and other large salps play a significant role in carbon transport to the seafloor. We calculated that faecal pellets from these swarms could have contributed up to 67 % of the mean organic daily carbon flux in the area. This suggests that the flux of carbon from salp swarms are not accurately captured in current estimates. Conclusion: This study contributes information on salp abundance and biomass to a relatively understudied field, improving estimates for biogeochemical cycles.

  • The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom
    lopmen ve ta e l B Williamson, Cell Dev Biol 2012, 1:1 D io & l l o l g DOI: 10.4172/2168-9296.1000101 e y C Cell & Developmental Biology ISSN: 2168-9296 Research Article Open Access The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom Abstract The larval transfer hypothesis states that larvae originated as adults in other taxa and their genomes were transferred by hybridization. It contests the view that larvae and corresponding adults evolved from common ancestors. The present paper reviews the life histories of chordates, and it interprets them in terms of the larval transfer hypothesis. It is the first paper to apply the hypothesis to craniates. I claim that the larvae of tunicates were acquired from adult larvaceans, the larvae of lampreys from adult cephalochordates, the larvae of lungfishes from adult craniate tadpoles, and the larvae of ray-finned fishes from other ray-finned fishes in different families. The occurrence of larvae in some fishes and their absence in others is correlated with reproductive behavior. Adult amphibians evolved from adult fishes, but larval amphibians did not evolve from either adult or larval fishes. I submit that [1] early amphibians had no larvae and that several families of urodeles and one subfamily of anurans have retained direct development, [2] the tadpole larvae of anurans and urodeles were acquired separately from different Mesozoic adult tadpoles, and [3] the post-tadpole larvae of salamanders were acquired from adults of other urodeles. Reptiles, birds and mammals probably evolved from amphibians that never acquired larvae.

To address this knowledge gap, we provide a holistic trophic characterization of a jelly web in the eastern tropical Atlantic, based on δ13C and δ15N stable isotope analysis of a unique gelatinous zooplankton sample set. The jelly web covered most of the isotopic niche space of the entire planktonic oceanic food web, spanning > 3 tro- phic levels, ranging from herbivores (e.g., pyrosomes) to higher predators (e.g., ctenophores), highlighting the diverse functional roles and broad possible food web relevance of gelatinous zooplankton.

  • Towards an Understanding of Salp Swarm Dynamics. ICES CM 2002/N
    CM 2002/ N:12 Towards an understanding of salp swarm dynamics by Patricia Kremer ABSTRACT Species of salps are characterized by intermittent blooms. Several studies have documented the importance of physical processes both in providing seed stocks of salps and creating an environment that is favorable for the rapid increase of salp populations. Although salps are typically oceanic, most observations of bloom dynamics have been made in more accessible inshore waters, so it is difficult to assess how frequent and widespread these swarms are. A review and comparison of existing data is helping to define geographic “hot spots” for salp blooms as well as the necessary physical and biological precursors. Although at this point, the review is far from complete, several generalities are emerging. The details of the physical forcing functions vary, but the overall physical regime seems to require a region of pulsed mixing of oceanic water that results in a relatively high standing stock of autotrophs. For a salp bloom to occur, there also needs to be an adequate seed population of salps and sufficient sustained primary production to support the biomass of the salp population as the bloom develops. As non-selective filter feeders, salps are able to remove a wide range of particulates from the water column, transforming the undigested portion into fast sinking feces. Therefore, when salps occur at high densities, the water is characterized by low abundance of other plankton, with obvious trophic implications.

  • British Pelagic Tunicates, and the Choice of the 21 Species
    REVIEWS BULLETIN OF MARINE SCIENCE, 34(1): 175-176, 1984 BRITISHPELAGICTUNICATES.J. H. Fraser. Synopses of the British Fauna (New Series) No. 20. Cambridge University Press. 1982. 57 pp., 23 figures, glossary and index. Soft cover. $12.95. The Synopses of the British Fauna, of which this is No. 20 in the series, are designed as field and laboratory pocketbooks for the use of amateur and profes- sional naturalists. They are intended to bridge the gap between popular field guides and professional treatises and monographs. This slim little volume on pelagic tunicates seems to serve this purpose admirably. Each of the 21 species of Appendicularians and Thaliaceans treated in this work is illustrated with line drawings showing the pertinent characters required for identification. Both aggregate and solitary forms are shown when such occur. Descriptions are brief but adequate and there are notes on distribution and abun- dance where pertinent. A very useful account of anatomical structures, life his- tories, ecology and distribution is given for each major group. There is also a glossary, index and a useful list of references. The introduction serves also to inform the reader on methods of capture, preservation and labeling. Complete keys are given for all levels from class to family, genus and species. The author is to be congratulated on the clarity of the couplet definitions. One may be puzzled, however, by the title, British Pelagic Tunicates, and the choice of the 21 species. Under the Appendicularia Fraser states that only Oi- kopleura dioica and Fritillaria borealis are found in British estuaries and inshore waters while Oikopleura labradoriensis is frequent in areas around the British Isles but is unlikely to be found in inshore waters.
