Parasitic Isopod

The distribution of the recently discovered association of the parasitic isopod Ceratothoa steindachneri (Isopoda: Cymothoidae) with the lesser weever fish (Echiichthys vipera) is reported. Ceratothoa steindachneri appears to have colonized the south-west coast of the UK between the 1960s and the 1980s, possibly as a result of range expansion due to climate change. The occurrence of C. steindachneri in E. vipera from Arcachon, France, indicates that this association has been occurring for over 100 years. Our data confirm that C. steindachneri is able to parasitize a broad range of fish hosts.

Microzooplankton community composition, abundance, biomass and grazing impact were assessed, along with measurements of ciliate growth and mortality, during the onset of the spring bloom in the north-east Atlantic. The study was undertaken as part of the UK Biogeochemical Ocean Flux Study during 1 May to 15 June 1990. The microzooplankton community was composed of protozoans and metazoan developmental stages with respective mixed-layer depth integrated biomass values ranging from 127 to 638 and 74 to 394 mg C m−2. High numbers of aloricate ciliates (up to 35,000 cells l−1) dominated the microzooplankton community during early May prior to the onset of the spring bloom. Ciliate abundance then declined rapidly during mid-May with community growth rates ranging from −0·71 to 0·23 d−1. High abundances of metazoplankton (up to 400 l−1) were also recorded at this time and may have contributed to the decline in ciliate numbers. In late May and early June the protozoan community comprised a more even mix of dinoflagellates, tintinnids and aloricate ciliates. Phytoplankton mortality rates, measured using a dilution technique, ranged from 0·2 to 0·5 d−1. The microzooplankton consumed 8 to 44 μg C l−1 d−1, equivalent to between 16 and 40% of the chlorophyll biomass and 38 and 154% of primary production. These high rates of herbivory reflect the predominance of small (<5 μm in length) phytoplankton cells present throughout the first half of the study and support previous studies demonstrating the microzooplankton to be the main grazers of phytoplankton in the north-east Atlantic. However, there is also evidence that a disparity between predator and prey may have prevented a response by the microzooplankton to rapid increases in phytoplankton biomass and production during the spring bloom.

A further 69 recaptures are reported from a tagging study of pelagic sharks initiated in 1970 in the north-east Atlantic. Galeorhinus galeus tagged in England were recaptured in the eastern Atlantic from southern Spain to north-west of Iceland. Among the 42 G. galeus recaptured the longest time at liberty was about 12 years and the greatest distance travelled was 2461 km. Among the 21 Prionace glauca recaptured the l ongest time at liberty was 10.7 years, and seven sharks moved distances between 4362 and 7176 km. One shark tagged in south-west England was recaptured in the South Atlantic off South America. An Isurus oxyrinchus was at liberty for 4–6 years and a Lamna nasus for up to about 13 years. Lamna nasus were recaptured from northern Norway to northern Spain. The growth rates of the tagged sharks were close to the predicted values for G. galeus, were slower for P. glauca and faster for L. nasus.

Since the early 1950s a sport fishery for sharks has existed off south-west England. On average some 5000 sharks are taken annually on rod and line between May and October. The catch consists almost entirely of blue sharks, the majority of which are immature or adolescent females, limited numbers of the porbeagle, Lamna nasus Bonnaterre, mako, Isurus oxyrinchus Rafinesque and very occasionally the thresher, Alopias vulpinus Bonnaterre.

This chapter assesses the legal regime of the North-East Atlantic and the North Sea. It begins by discussing some of the geographical, economic, environmental, strategic, and geo-political factors that are shaping the very distinctive regional regimes that give effect to the basic principles, as well as to many of the substantive provisions embodied in the UN Nations Convention on the Law of the Sea (LOSC) and related agreements. It provides a summary of the various maritime jurisdictional zones and boundaries claimed by the twelve coastal States that make-up the region: Belgium, Denmark, France, Germany, Iceland, Ireland, the Netherlands, Norway, Portugal, Spain, Sweden, and the UK. This is followed by a description of some of the principal regional bodies responsible for formulating and implementing various aspects of the law of the sea, including the regional seas environmental body, the EU and several fisheries management organizations.

The article focuses on calendar-ceremonial folklore of Novgorod region as an important component of folklore song traditions of the region. The musical and poetical forms of the calendar are considered in terms of type, genre and realm. The author is the first to systematize the data about calendar folklore recordings made in Novgorod region by various collectors in the 1960s - 1990s. The author gives special attention to the results of field studies of Saint Petersburg Conservatory named after N.A. Rimski-Korsakov. The author introduces into scientific discourse a range of items of calendar folklore from the archive of the Conservatory (Maslenitsa, Christmas and Easter carols and yells). The specificity of Novgorod calendar traditions is connected with a special role of intoned yells serving a function of calling over ceremonial characters, and Christmas carols combining the features of folk and church melodics. Some folklore forms, recorded in Novgorod region, can be considered unique (the North-East Maslenitsa chants, the &ldquo;Piper&rdquo; song, the Easter callings). Taking into account the peculiarities of a genre composition of the calendar, the types of chants and the style features, the author outlines three historical-cultural zones in Novgorod region - the North-East, the South-West and the Central. The research results can be used for mapping&nbsp; the calendar folklore chants of Russia&rsquo;s North-West, and for the further study of music folklore traditions of Novgorod region together with other folklore genres.&nbsp; &nbsp;

Harris is supposed to derive its name from the Gaelic “na hardibh,” a designation signifying “the heights.” The term is appropriate in that the most mountainous parts of the Long Island lie within its boundaries.South Harris forms a natural geographical division for it is divided, from North Harris by a narrow neck of iand at Tarbert separating the eastern from the western seas. This isthmus is less than half a mile across. In addition to South Harris proper, this memoir deals also with the Isle of Scalpay and neighbouring islets off the north-east coast, the Isle of Taran-say on the north-west, and several islands off the south-west coast in the Sound of Harris, of which the principal ones are Ensay, Killegray, Groay, Lingay, and Gilsay.
