Coral Composition

Degradation and loss of critical coastal habitats has significant ramifications for marine fisheries, such that knowledge of changes in habitat quality and quantity are fundamental to effective ecosystem management. This study explores changes in the structure of coral reef habitats, specifically changes in coral cover and composition, in Moorea, French Polynesia, to assess the independent and combined effects of different disturbances since 1979. During this period, reefs on the north coast have been subject to coral bleaching, severe tropical storms, as well as outbreaks ofAcanthaster. Coral cover varied significantly among years, showing marked declines during some, but not all, disturbances. The greatest rates of coral loss coincided with outbreaks ofA. planci. Moreover, successive disturbances have had differential effects among coral genera, leading to strong directional shifts in coral composition.Acroporais declining in abundance and coral assemblages are becoming increasingly dominated byPocillopora and Porites. Observed changes in the cover and composition of corals are likely to have further significant impacts on the reef fish assemblages. Given that significant disturbances have been mostly associated with outbreaks ofA. planci, rather than climate change, effective ecosystem management may reduce and/or delay impending effects of climate change.

The tropical western South Atlantic, which includes a substantial portion of the Brazilian Exclusive Economic Zone, is a region of endemism broadly recognized as being of prime importance for the conservation of the marine biodiversity. The north coast of Brazil, which comprises the states of Amapá, Pará and Maranhão from the mouth of the rio Oiapoque to the mouth of the rio Parnaíba, harbors the largest continuous mangrove in the world, with approximately 8,900 km2. The high discharge of freshwater and continental sediments in the delta of the Amazonas affects the regime of tides, ocean currents, and several oceanographic processes of the north coast, with direct impact on the composition of the biota found in the region. Despite its economic value and intrinsic biological relevance, several aspects of the diversity of the marine and estuarine fishes of the region are poorly known. This situation results mainly from a historical imbalance in terms of the number of studies devoted to increasing the knowledge of the marine biota along the Brazilian coast, such as those dealing with species inventory and taxonomic revisions, which are typically concentrated in the south and southwestern portions of the country. The scientific production focused on marine organisms of the north coast is also imbalanced, and reflects the relatively small number of taxonomists and research groups working on that subject. The insufficient knowledge of the biodiversity of the marine and estuarine fishes of the north coast is an impediment to the implementation of adequate public policies aimed at the management of natural resources in the region. In the long term, that situation is potentially harmful in terms of conservation of a still poorly known biota. A better understanding of the marine fish fauna of the north coast of Brazil will be achieved only through the investment in scientific research and personnel training in systematics and biogeography, coupled with the modernization of the current infrastructure and expansion of scientific collections of the region.

Knowledge about factors that are important in coral reef growth help us to understand how reef ecosystems react following major anthropogenic and environmental disturbances. In addition, they may help the industry understand how aquarists can improve the health of their corals. I have studied environmental and climate effects on corals on fringing reefs in Jamaica. Radial growth rates (mm/yr) of non-branching corals calculated on an annual basis from 2000–2008 showed few significant differences either spatially or temporally along the north coast, although growth rates tended to be higher on reefs of higher rugosity and lower macroalgal cover. I have also reconstructed recruitment patterns, using growth modelling, for non-branching corals at sites on the north coast of Jamaica near Discovery Bay, and near Kingston Harbour, on the south coast. For all the sites, recruitment of non-branching corals was lowered due to hurricanes or severe storms. For 1560 non-branching corals at sites along the north coast of Jamaica, from Rio Bueno to Pear Tree, there was a significant difference in estimated coral recruitment in years when there were no storms or hurricanes by comparison to years when storms and hurricanes impacted the area. For 347 non-branching corals at sites in the Port Royal Cays on the south coast, there was a significant difference in estimated coral recruitment in years when there were no storms or hurricanes by comparison to years when storms and hurricanes impacted the area. Interestingly, recruitment of Siderastrea siderea on to the side of the ship channel at Rackham's Cay (~100 m from the path taken by large ships) outside Kingston Harbour had been consistent since its construction. These findings have important implications for better understanding the impacts of tropical storms on coral reefs and for aquarists to better maintain coral reef species in artificial environments.

This paper explores the application of citizen science to help generation of scientific data and capacity-building, and so underpin scientific ideas and policy development in the area of coral reef management, on the coral reefs of Jamaica. From 2000 to 2008, ninety Earthwatch volunteers were trained in coral reef data acquisition and analysis and made over 6,000 measurements on fringing reef sites along the north coast of Jamaica. Their work showed that while recruitment of small corals is returning after the major bleaching event of 2005, larger corals are not necessarily so resilient and so need careful management if the reefs are to survive such major extreme events. These findings were used in the development of an action plan for Jamaican coral reefs, presented to the Jamaican National Environmental Protection Agency. It was agreed that a number of themes and tactics need to be implemented in order to facilitate coral reef conservation in the Caribbean. The use of volunteers and citizen scientists from both developed and developing countries can help in forging links which can assist in data collection and analysis and, ultimately, in ecosystem management and policy development.

In a recent issue of Bijdragen tot de Taal-, Land- en Volkenkunde, Andrew McWilliam undertakes an interesting study of the elusive traditional Timorese domain of Ade, which is often mentioned in Portuguese and Dutch sources of the seventeenth and eighteenth centuries. His conclusion is briefly that there is a close affinity with the domain of Vemasse (Oymassin) on the north coast of present Timor Leste. While I agree with his conclusion, I would like to point out a few unpublished Dutch sources which provide more detailed information on Ade and its location.

Infor Mation

The North Coast of Brazil is a biogeographical area of the Exclusive Economic Zone of Brazil that share environmental features with region under influence of the Plume of the rio Amazon and Orinoco. Despite the relevance of the region’s fish fauna, in biogeo-graphic, ecologic, and commercial terms, this area is poorly known. This study presents the most complete and updated list of the bony fish fauna from the North Coast of Brazil, aiming to minimize our knowledge gap on such region's biodiversity. The main sources of infor-mation were records from zoological collections, inventories obtained during the surveys of the Research and Conservation National Center of Northern Marine Biodiversity and collec-tions from the authors. A total of 787 species of the Teleostei were recorded off the North Coast of Brazil and adjacent waters, representing 156 families and 45 orders. Most (531) of these species are coastal, 256 inhabit deeper water, and 31 pelagic (oceanic) species are com-mon to both the internal and external continental shelf, of which 54 represent new records. Given the progressive intensification of fisheries and increasing incentives for the exploita-tion of the local gas and oil reserves, a more adequate inventory of the marine fish fauna of the North Coast of Brazil is fundamentally important for the management of the region’s aquatic biodiversity.

Negative Impacts

Objective: The aim of this study is to find negative impacts of the construction of the modern infrastructure of the toll road and find out a good solution in East Timor. Methods: The research methodology used is descriptive qualitative research methodology, namely, collecting data, interviewing key persons, making data deduction, analyzing data, drawing conclusions, and expressing recommendations, especially for the contractors and for the government. Results: The construction of the toll road infrastructure megaprojects in the new country of Timor-Leste has both positive and negative impacts. The negative impact is huge and this is not taken into account by the contractors and the government in the construction of the Suai-Beasu toll road that connects the city of Suai on the South coast and the town of Dili on the North coast of the Democratic Republic of Timor-Leste. Hence, the recommendations suggested for the contractors and the government are to implement the aspirations of the communities, especially in the fair and just payment for the area used for the projects and building new cross-traffic for the residents alongside the toll road. Conclusion: The presence of the toll road had positive impacts but there are several negative impacts on the lives of the Suai people, therefore, it is better that if the government and the contractors pay serious attention to overcome the negative impacts.

A New Species

South Georgia is a remote sub-Antarctic island, considered a marine biodiversity ‘hotspot’ in the Southern Ocean. During a survey along the north coast of South Georgia several marine planarians were found. One of the specimens was a new species ofAllogenus(Uteriporidae), which is described here asAllogenus sluysisp. nov. The new species has the characteristics of the genus and can be distinguished from the type and only known species,Allogenus kerguelensis, by its smaller size, blackish-brown pigmentation, presence of three retinal cells in each eye cup, position of its testes half-way between the ventral and dorsal body surfaces or at a slightly more ventral position, and by having an ejaculatory duct that opens centrally at the tip of the penis papilla. The presently known geographical distribution ofAllogenus, the heterogeneous marine planarian species composition in South Georgia, and the distribution of these species in this region are in agreement with a previously proposed vicariance hypothesis, albeit that dispersal cannot be ruled out.

Pati is a region on the north coast, according to the hypothesis of the researcher, the region is divided into three categories. The northern regions are more religious, the central is more plural, while the southern region is in the middle. In the central region there are many relics of tombs believed to be the those of the Muslim proselytizers in the area of Pati. The one that attracts the researcher is a tomb in the Gambiran area, where there are five local Muslim saints buried, one of them belons to mbah Hendro Kusumo, the son of Syech Ahmad Mutamakkin. This article attempts to trace back the spreading of Islam in Pati based on the existence of thetomb of Mbah Hendro Kusumo. It wants to answer question of whethere the existence of his tomb is due to his studying there or marital relationship, and how it relates to the spreading of Islam.Keywords: Mbah Hendro Kusumo, Traces of Islamic Dakwah, Islam

The Tyara site, KkFb-7 in the National Museum catalogue and site file, faces the north coast of the Ungava mainland and rests on the west shore of Sugluk Island (Fig. 1). That island stands about five hundred yards from the mainland and from Sugluk Inlet, one of the few good harbors on that coast. This handsome little island, about one and one-half miles long and as wide, consists of rounded, rugged, hardrock hills that shelter well-vegetated, generally flat-floored valleys. The valleys often contain marshy patches. The shore, of variable incline, is quite jagged, a result of abrupt rock outcrops projecting seaward from brief stretches of sandy beach. The shore facing the mainland is, therefore, quite convenient for small boat use. Dark grey gneisses seem to predominate, although they are often cut by dykes and veins of lighter material, notably quartz. The dense, green valley and hillside vegetation includes willows, mosses, grasses, lichens, and a pleasant profusion of arctic wild flowers (Polunin 1948, Pt. III). I was told at Sugluk that at the head of the inlet, willows, growing in protected situations, reach the thickness of a man's wrist.
