AbstractThe adaptive genetic variation in response to heterogeneous habitats of the Indian Ocean was investigated in the Indian oil sardine using ddRAD sequencing to understand the subpopulation structure, stock complexity, mechanisms of resilience, and vulnerability in the face of climate change. Samples were collected from different ecoregions of the Indian ocean and ddRAD sequencing was carried out. Population genetic analyses revealed that samples from the Gulf of Oman significantly diverged from other Indian Ocean samples. SNP allele-environment correlation revealed the presence of candidate loci correlated with the environmental variables like annual sea surface temperature, chlorophyll-a, and dissolved oxygen concentration which might represent genomic regions allegedly diverging as a result of local adaptation. Larval dispersal modelling along the southwest coast of India indicated a high dispersal rate. The two major subpopulations (Gulf of Oman and Indian) need to be managed regionally to ensure the preservation of genetic diversity, which is crucial for climatic resilience.

Just as the world united in grief after the tragic carnage of 9/11, so too hasthe world become one after the cataclysmic tsunami that has claimed,according to Australia’s Sydney Morning Herald (February 8, 2005),295,608 lives, and has affected 11 countries in the Indian Ocean region.The tsunami destroyed entire villages and families. Long after thehouses have been rebuilt and the people have returned to a kind of normalcyin their lives, the effects of this catastrophe will continue to be felt.Local economies and the infrastructures needed to support them will haveto be rebuilt, and there will be the continuing psychological impact on thesurvivors, who will always feel guilty for having survived and who willnever be free of the pain of losing their loved ones.No one has been unaffected by the tsunami, although some of us, bythe grace of God (swt), have not felt its devastation. As the English adagegoes, every cloud has a silver lining. And in the face of such an awesomenatural calamity, we have seen the best side of humanity, as people rush toprovide aid and assistance to the survivors.The tsunami has also allowed those working in poverty relief and aidprograms elsewhere to turn the spotlight on their efforts to avert othercalamities that are of the same magnitude but occur at a much slower pace.Among such people is Stephen Lewis, the UN Secretary-General’s SpecialEnvoy for HIV/AIDS in Africa, who pointed out during an interview on CBCradio (January 12, 2005) that more than 2 million people in Africa die eachyear of AIDS. And then there is Rabbi Michael Lerner, who reminded us inhis essay in Tikkun (January 5, 2005) of a recent UN report that 29,000 childrendie every day from avoidable diseases and malnutrition.Calamities and their accompanying suffering and struggles are tests forhumanity. They remind us that we are not in control of the universe, andthus are a lesson in humility. They remind us that life is fragile and can betaken from us at a time and in a way that we do not expect, and thus are alesson in priorities and perspective, a check against the materialism andhedonism that is overtaking our consumer capitalist lives. Who wouldreally care that they do not own the latest iPod if they knew that they wereto die tomorrow? ...

<p><em>Since the tsunami in 2004 in the Indian Ocean, studies of the megatrust tsunami have been increasing. One of the reasons is because the megatrust tsunami can cause large numbers of casualties, as has happened in Aceh and Mentawai (Indonesia). The threat of a megatrust tsunami now stretches along the coastline of the southern island of Java. Communities who are in the southern part of Java, ideally have the ability to be prepared to face a tsunami disaster. Therefore, an assessment of community preparedness in the face of a tsunami in Purworejo Regency is an urgency, because Purworejo is one of the regencies directly adjacent to the ocean in the south of Java Island. This study uses a combination of questionnaires, interviews, observation and documentation to obtain data. This study provides information on the classification of villages along the coast of Purworejo in relation to the level of preparedness to face the threat of a tsunami disaster. The result is that from 16 villages 2 of them are of high status, 2 are low and the rest are moderate.</em></p>

ABSTRACTWhite Africans are particularly associated with the troubles South Africa and Zimbabwe have faced throughout their histories. The story of the Franco-Mauritians, the white elite of Mauritius, and how they have fared during more than forty years since the Indian Ocean island gained independence, is much less known. However, their case is relevant as a distinctive example when attempting to understand white Africans in postcolonial settings. Unlike whites elsewhere on the continent, Franco-Mauritians did not apply brute force in order to defend their position in the face of independence. Yet the society that emerged from the struggle over independence is one shaped by dominant beliefs about ethnicity. As this article shows, despite a number of inverse effects Franco-Mauritians have benefited from this unexpected twist, and part of the explanation for their ability to maintain their elite position lies therefore in the complex reality of ethnic diversity in postcolonial Mauritius.

Scholarly Attention

Scholars of Islam in Southeast Asia and the history of the Malay-Indonesianworld have long been aware of periods of intense contacts between the OttomanEmpire and the region. Most widely known in this context are the politicalexchanges between the Sultanate of Aceh and the Ottoman Empire ofthe sixteenth century in the face of Portuguese maritime domination in SoutheastAsia. Regional calls for Ottoman aid against the expanding Europeanpowers by Muslim rulers were voiced in the nineteenth century. Despite thislapse in documented political contacts, however, connections between the tworegions were also sustained and developed further throughout the interveningcenturies on a variety of levels, most prominently in the economic, religious,and intellectual spheres.Despite the pioneering work of scholars such as Anthony Reid since the1960s, these connections, including inter alia the holy cities and Yemen’sHadhramaut region, both important centers of Islamic learning for SoutheastAsian Muslims and the source of strong migrant communities settling in theMalay-Indonesian world, have received scant scholarly attention. It is againstthis background that the British Academy-funded research project “Islam,Trade, and Politics across the Indian Ocean” and the volume at hand, whichrepresents one of its major fruits, brings together new innovative research onall of the various aspects of this particular relationship. Hereby it must benoted that its scope extends at times well beyond the Ottoman era also intothe Republican era, and that, importantly, much of the documentary evidencerelied upon derives from newly discovered archival sources.The volume is divided into three thematic parts, preceded by two introductorychapters by the editors and Anthony Reid, respectively, which set thestage for the remainder of the book by reviewing the relationship’s general ...

Introduction: The entry of dust particles into water areas, which has increased sharply in recent years, causes a lot of environmental damage. The Persian Gulf and the Gulf of Oman are among the water areas that are covered with dust many times of the year. Materials and methods: In this study, a severe dust from July 27 to 31, 2018 is analyzed, in which a large part of the Persian Gulf, Oman Sea and the western part of the Indian Ocean was involved. To study this phenomenon from different perspectives, satellite products, visibility from synoptic stations and synoptic maps were analyzed and the output of two numerical dust models of NASA-GEOS and DREAM8-MACC were examined. To qualitative and quantitative evaluate of the model outputs, the Aerosol Optical Depth (AOD) of TERRA/MODIS was used. Results: Satellite imagery shows that in this case study, parts of the Persian Gulf and the Sea of Oman were affected by dust, and on July 30, dust particles entered the western half of the Indian Ocean. Comparison of model outputs with satellite data resulted that both models underestimate the AOD values, especially over water, and do not show well the entrance of dust particles into the eastern part of the Persian Gulf, the Gulf of Oman and the western half of the Indian Ocean. Conclusion: Qualitative and quantitative comparison of AOD output of the two models with satellite data showed that the NASA-GEOS model had better performance and its output correlation with observational data was higher.

The box crab Calappa exanthematosa Alcock & Anderson, 1894, originally described from the Bay of Bengal, has been synonymised under C. japonica Ortmann, 1892 (type locality Japan), since 1937. Comparisons of specimens from the Gulf of Oman and India reveal consistent differences in the live colour of material from the rest of the Indo-West Pacific region, carapace (general form, shape of lateral teeth, position of longitudinal gastro-cardiac grooves, structures of posterior region), pterygostomian lobe, chela, male abdominal somite 6, male telson and G1. Calappa exanthematosa is here recognised as a distinct species, redescribed, and illustrated.

The break–up of Gondwanaland and dispersal of several of its component continental fragments, which eventually formed the margins of the Indian Ocean, have produced an ocean basin of enormous variety, both in relief and in origin of seafloor features. The western half of the Indian Ocean alone contains every type of tectonic plate boundary, both active and fossil, and, along with some of the deepest fracture zones, the most complex mid–ocean ridge configurations and some of the thickest sedimentary sequences in the world's ocean basins. This ocean is one of the most diverse on the face of the globe. We explore the evolution of the morphology of the Indian Ocean floor, and discuss the effect of its variations, maxima and minima, on the interconnectivity of the ocean's water masses.
