False Killer Whales — Enchanting Cetaceans of Dominica Text and photos by Lawson Wood False Killer Whales — Enchanting Cetaceans of Dominica 74 X-RAY MAG : 42 : 2011 EDITORIAL FEATURES TRAVEL NEWS EQUIPMENT BOOKS SCIENCE & ECOLOGY EDUCATION PROFILES PORTFOLIO CLASSIFIED travel Dominica Once or twice in a rare Blue Moon, opportu- nity sometimes comes along and hits you on the head—or in my case, I was hit on the head—by a juvenile sperm whale. Let me recap. Along with a small group of like-minded conservationists and underwa- ter photographers, we were working under a special per- mit issued by the Ministry of Agriculture and Fisheries on the Island of Dominica (pronounced DOMINEEKA) to try and iden- tify returning sperm whales and other cetaceans. Dominica is the youngest of the Caribbean islands and is flanked by Guadeloupe to the north and Martinique to the south, which are both French colonies. Inevitably, many of the locals speak a derivative of a French, Carib and West African creole known as Kwéyòl. Ancestors of the original Carib Indians, the Kalinago still live by traditional fishing and farming methods and are rather distinc- tive in appearance, resembling South American Amazon tribes and are much shorter in stature. The Kalinago name for the island is Wai’tukubuli. The local beer is called Kubuli! Extremely mountainous in aspect, two of the peaks are over 1,300 metres (4,500ft).

For sure, this was no ordinary Caribbean holiday! During the first couple of weeks we visited no fewer than ten islands (Antigua, Barbuda, Montserrat, Dominica, Guadeloupe, Martinique, St Lucia, St Vincent, Barbados and Grenada), a logistical feat of some magnitude. With plenty of LIAT flights (the islanders refer to LIAT as ‘Leave Island any Time’ and ‘Luggage in Another Terminal’ to name but two of the many funny phrases coined from LIAT) and unreliable AVIS car hire reservations, we had our work cut out, but in the end, all worked out! It’s always strange birding on islands with so few targets, but with so many islands to pack-in, we were never really short of things to do. All of the endemics showed well and there were some cracking highlights, including the four smart endemic amazons, the rare Grenada Dove, the superb Lesser Antillean Barn Owl, the unique tremblers and White-breasted Thrashers, and a series of colourful endemic orioles to name just a few! At the end of the Lesser Antilles adventure we enjoyed a few days on Trinidad.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by OAR@UM Asia Pacific Viewpoint, Vol. 51, No. 1, April 2010 ISSN 1360-7456, pp61–72 Islands and beers: Toasting a discriminatory approach to small island manufacturingapv_1414 61..72 Godfrey Baldacchino Island Studies Program, University of Prince Edward Island, 550 University Avenue, Charlottetown, PE, Canada C1A 4P3. Email: [email protected] Abstract: This paper explores the relationship between beers and island development, using a global sweep but with a special reference to the insular Pacific. It adopts a discriminatory approach, touching upon the role and impact that niche and bouquet beer manufacturing can have on the socioeconomic development of small islands. It departs from a personal observation: many small island jurisdictions have their own brewery. Indeed, the brewery could also be the island territory’s largest indigenous manufacturing concern. While small islands are associated with low manufactur- ing capacity and diseconomies of scale, nevertheless ‘a local brewery’ comes across, in many cases, as a profitable and glaring exception that speaks to the attractions and virtues of locality branding.

During my stay in Dominica, I had the opportunity to organize a teachers’ workshop with the assistance of the indigenous people of the Kalinago Territory. Although the teachers interact with Kalinago culture on a daily basis, we decided to explore the teachers’ knowledge of indigenous heritage and to challenge them in activities where they could put their knowledge into practice. We then drew animals, plants, tools and objects that are found in daily life in the Kalinago Territory. Later on in the workshop, we asked teachers about the Kalinago names that were printed on their tag names. Teachers were able to recognize some of these Kalinago names, and sometimes even the stories behind them. In this simple way, we started our workshop on indigenous history and heritage — because sometimes the most useful and meaningful learning resources are the ones we can find in our everyday life. This case study took place in Dominica; the island is also known by its Kalinago name, Wai’tu Kubuli, which means “tall is her body.” The Kalinago Territory is the home of the Kalinago people.

  • “In Remembrance of Susan Manning”: James Chandler, Franke
    “In Remembrance of Susan Manning”: James Chandler, Franke Institute for the Humanities, University of Chicago Annual Meeting of the Consortium of Humanities Centers and Institutes Hall Center for the Humanities, University of Kansas April 2013 Diminutive as she was in physical stature, Susan Manning was in all other respects a truly great woman. She was both dignified and unpretentious. At once smart and learned and wise. Tremendously energetic, even in the face of serious debility. Her presence graced any gathering she joined and elevated any enterprise to which she lent her great gifts. This enterprise, CHCI, was lucky enough to have her on its advisory board for most of the last seven year of her truncated life. She was a wonderful presence in our midst: imaginative, steady, principled, humane, and thoughtful. To know Susan was to admire her. To know her well was to aspire to be her friend. To know her work, on the page and in the many institutions she tirelessly served, was to recognize intellectual and academic virtue of the highest order. Our loss is enormous, commensurate with her greatness, and we feel it with special keenness here today. The passing of great women and men leaves us with a large hole in our lives, but their own lives make for extraordinary reading after they are gone. I’ve read several obituaries about Susan since her death, and I learned much about her that I hadn’t known. I knew that she was born in Scotland and moved to the suburbs of Oxford when she was about nine years old.

  • Bathing Water Profile for Eyemouth
    Bathing Water Profile for Eyemouth Eyemouth, Scotland __________________ Current water classification https://www2.sepa.org.uk/BathingWaters/Classifications.aspx Today’s water quality forecast http://apps.sepa.org.uk/bathingwaters/Predictions.aspx _____________ Description The bathing water is situated next to Eyemouth town in the Scottish Borders. It is a small, shallow sandy bay of about 0.3 km in length. The beach is popular with families during the summer months. During high and low tides the approximate distance to the water’s edge can vary from 0–100 metres. For local tide information see: http://easytide.ukho.gov.uk/EasyTide/index.aspx Site details Local authority Scottish Borders Council Year of designation 1999 Water sampling NT 94463 64524 location EC bathing water ID UKS7616022 Catchment description A catchment area of 120 km2 drains into Eyemouth bathing water. The main rivers in the bathing water catchment are the Eye Water, Ale Water, Horn Burn and the North Burn. Agriculture is the major land use in the catchment. The upland areas are almost exclusively livestock rearing areas whereas the lower parts of the catchment include more arable farming. The catchment includes the urban area of Eyemouth town. Average summer rainfall for the region is 296 mm compared to 331 mm across Scotland as a whole. Risks to water quality This bathing water is subject to short term pollution when heavy rainfall washes bacteria into the sea. Pollution risks include agricultural run-off and combined sewer overflows. These are highlighted on Map 1. There is a risk that water pollution may occur after heavy rainfall.
