Neurodevelopmental effects of maternal nutritional status and exposure to methylmercury from eating fish during pregnancy

Fish contain nutrients that promote optimal brain growth and development but also contain methylmercury (MeHg) that can have toxic effects. The present study tested the hypothesis that the intake of selected nutrients in fish or measures of maternal nutritional status may represent important confounders when estimating the effects of prenatal methylmercury exposure on child development. The study took place in the Republic of Seychelles, an Indian Ocean archipelago where fish consumption is high. A longitudinal cohort study design was used. A total of 300 mothers were enrolled early in pregnancy. Nutrients considered to be important for brain development were measured during pregnancy along with prenatal MeHg exposure. The children were evaluated periodically to age 30 months. There were 229 children with complete outcome and covariate data for analysis. The primary endpoint was the Bayley Scales of Infant Development-II (BSID-II), administered at 9 and 30 months of age. Combinations of four secondary measures of infant cognition and memory were also given at 5, 9 and 25 months. Cohort mothers consumed an average of 537 g of fish (nine meals containing fish) per week. The average prenatal MeHg exposure was 5.9 ppm in maternal hair. The primary analysis examined the associations between MeHg, maternal nutritional measures and children's scores on the BSID-II and showed an adverse association between MeHg and the mean Psychomotor Developmental Index (PDI) score at 30 months. Secondary analyses of the association between the PDI and only MeHg alone or nutritional factors alone showed only a borderline significant association between MeHg and the PDI at 30 months and no associations with nutritional factors. One experimental measure at 5 months of age was positively associated with iodine status, but not prenatal MeHg exposure. These findings suggest a possible confounding role of maternal nutrition in studies examining associations between prenatal MeHg exposures and developmental outcomes in children.

Colonising Poso : the diary of Controleur Emile Gobee, June 1909 - May 1910

"While the colonisation of Central Sulawesi was a process that was unique to the particular demographic, social, political and economic characteristics of the region, in broad terms it replicated Dutch colonial policy and practice in the rest of the archipelago at the beginning of the 20th century. The diary of Aspirant Controleur Emile Gobee, records the process which imposed the relocation and resettlement of the Pamona people of the Poso region of Central Sulawesi into villages and therefore began a dramatic process of change. The document provides a rare example of the process of colonialism and goes to the heart of understanding the nature of the colonial project in the Dutch East Indies."--Publisher's website.
"The 1909-10 diary of Aspirant Controleur Emile Goběe, of Poso, Sulawesi in the Dutch East Indies, with a scholarly introduction that explains the significance of Dutch colonial and missionary intervention, which intentionally destroyed traditional cultures and lifestyles. During the time covered by this diary, the administration moved entire villages to places where they could be observed, changed their farming practices, and introduced trade and Christianity." -- Publisher.

Missionary Albert Kruyt and colonial modernity in the Dutch East Indies

Intense debates emerged in the Dutch East Indies during the course of the third decade of the twentieth century concerning the role of missionaries in the development of the Outer Islands of the Indonesian archipelago. Ostensibly concerning “native welfare”, disagreement fundamentally reflected underlying fractures within the Dutch nation, projected through its “colonial mission” concerning the nature of modernity. While the main focus appeared to be a disagreement concerning the goals of mission and government agencies, it would be too simplistic to characterise the debate as one between adherents of a secular versus a religious world view. This paper considers the question of “missions and modernity” in the context of this debate about “native development” in the Dutch East Indies through the prism of the Poso mission in Central Sulawesi, headed by missionary Albert Kruyt, one of the foremost missionaries of his day.

The reliance on distant resources for egg formation in high Arctic breeding barnacle geese Branta leucopsis

Breeding in the high Arctic is time constrained and animals should therefore start with their annual reproduction as early as possible. To allow for such early reproduction in migratory birds, females arrive at the breeding grounds either with body stores or they try to rapidly develop their eggs after arrival using local resources. Svalbard breeding barnacle geese Branta leucopsis have to fly non-stop for about 1100 km from their last continental staging site to the archipelago making the transport of body stores costly. However, environmental conditions at the breeding grounds are highly unpredictable favouring residual body stores allowing for egg production after arrival on the breeding grounds. We estimated the reliance on southern continental resources, i.e. body stores for egg formation, in barnacle geese using stable isotope ratios in the geese's forage along the flyway and in their eggs. Females adopted mixed breeding strategies by using southern resources as well as local resources to varying extents for egg formation. Southern capital in lipid-free yolk averaged 41% (range: 23-65%), early laid eggs containing more southern capital than eggs laid late in the season. Yolk lipids and albumen did not vary over time and averaged a southern capital proportion of 54% (range: 32-73%) and 47% (range: 25-88%), respectively. Our findings indicate that female geese vary the use of southern resources when synthesising their eggs and this allocation also varies among egg tissues. Their mixed and flexible use of distant and local resources potentially allows for adaptive adjustments to environmental conditions encountered at the archipelago just before breeding.

Challenges in conserving indigenous culture in Minahasa : culture, Genius Loci and the Indonesian Environmental Planning system

Culture and spirit of land is integral to Indigenous community meaning and identity. With colonisation, transmigration and assimilation policies and practices over the last 200 years, many Indigenous communities, like the Minahasa, have witnessed their culture, curatorial responsibilities, and their mythological associations to their lands eroded. Minahasa, meaning 'becoming one united', encompasses some eight ethnic communities who reside in the Minahasa regencies in the North Sulawesi Province on Sulawesi Island in Indonesia. The region was first colonised by the Portuguese in the 16th century, and then by the Dutch VOC (Verenigde Oostindische Compagnie) in the 17th and 18th centuries bringing a strong Christian Protestant faith to the communities that appropriated many of the cultural symbols and mythological narratives of the Minahasa, and now compromises the largest concentration of Christian faith in the Indonesian archipelago being one of the reasons why there was considerable political requests for the region to formally become a province of The Netherlands in the lead up to Indonesian independence in 1945.

North Sulawesi never developed any large empire like on other islands in the archipelago. In 670, the leaders of the different tribes, who all spoke different languages, met by a stone known as Watu Pinawetengan. There they founded a community of independent states, who would form one unit and stay together and would fight any outside enemies if they were attacked, and the Dutch used this cultural ethos to help unite the linguistically diverse Minahasa confederacy under their colonial regime. Integral to the Minahasa is the Watu Pinawetengan and the series of narratives that enjoin the Minahasan communities to this place and around Lake Tondano. With Indonesian governance considerable angst has been launched by the Minahasa about loss of local autonomy, generic Indonesian policies, and a lack of respect of Indigenous culture and non-mainstream religions within this predominantly Moslem nation. This paper reviews the state of knowledge as to the cultural associations and genius loci meanings of the Minahasa, to their landscape and place, cast against contemporary Indonesian 10 year plans and policies that seek to generically manage the collective Indonesian archipelago as one community and landscape. It is a critique about the Minahasan Indigenous land use and planning philosophies, against top-down generic land use and environmental policies and plans written in Jakarta for generic application across the Indonesian archipelago.

The use of molecular and morphological characters to resolve the taxonomic identity of cryptic species : the case of Miniopterus manavi (Chiroptera, Miniopteridae)

Based on recent molecular phylogenetic studies, the Old World bat family Miniopteridae, composed of species in the genus Miniopterus, has been shown to contain complex paraphyletic species, many of which are cryptic based on convergent morphological characters. Herein we resolve the phylogenetic relationships and taxonomy of the species complex M. manavi on Madagascar and in the Comoro Archipelago, where these animals occur in different bioclimatic zones. First using mitochondrial cytochrome-b sequence data to define clades and then morphology to corroborate the molecular data, including comparisons to type specimens, we demonstrate that animals identified as this taxon are a minimum of three species: M. manavi sensu stricto occurs in at least the central portion of the Central Highlands; M. griveaudi has a broad distribution in lowland northern and central western Madagascar and the Comoros (Anjouan and Grande Comore), and M. aelleni sp. n. has been found in northern and western Madagascar and the Comoros (Anjouan). In each case, these three clades were genetically divergent and monophyletic and the taxa are diagnosable based on different external and craniodental characters. One aspect that helped to define the systematics of this group was isolation of DNA from one of the paratypes of M. manavi collected in 1896 and new topotypic material. Miniopterus manavi is most closely allied to a recently described species, M. petersoni. At several localities, M. griveaudi and M. aelleni have been found in strict sympatry, and together with M. manavi sensu stricto show considerable convergence in morphological characters, but are not immediate sister taxa. In defining and resolving the systematics of cryptic species, such as miniopterid bats, the process of defining clades with molecular tools, segregating the specimens accordingly, and identifying corroborative morphological characters has been notably efficient.

Minahasan indigenous perspectives on place planning and management : tracing the indigenous culture through the lens of local wisdom

Indigenous cultures draw upon many thousands of years of residency and environmental adaptation offering unique knowledge resources to better understand our landscapes and environment. The Minahasan society, on the island of Sulawesi in the Indonesian archipelago, is one such Indigenous community. The Minahasan are the Indigenous community of northern Sulawesi, before the Portuguese and Dutch 1500-1900 colonization of this island, and the later nationalist cultural assimilation following post Indonesian independence. Thus, some 500 years of post-European contact and management can be contrasted against over I 00,000 years of Minahasan society. Further, the majority of this colonisation has been focused upon the coastal fringes resulting in a relatively intact Minahasan cultural landscape within the interior of northern Sulawesi focused upon the Tondano Lake catchment. This paper considers the importance of the Minahasan-formed cultural landscape, its importance to this culture, and the role and influence it continues to have in settlement formation and planning in northern Sulawesi despite conventional Indonesian and Western-informed sustainable urban and regional planning traditions and knowledge. It draws upon intensive qualitative research using 14 different villages, to analyse and compare local knowledge and land-relationships developed by the respective communities to manage and curate their unique characteristics as well as ensuring adaption without compromising their cultural, social and economic values. The research embodies this ethnoecological information in seeking to analyse historical and contemporary land use planning systems, and to offer a future planning perspective that will respect and endure this relationship and environmental management regime.

Population trends of Gentoo Penguins Pygoscelis Papua breeding at the Falkland Islands

The fourth archipelago-wide census of Gentoo Penguins Pygoscelis papua breeding at the Falkland Islands was conducted from 24 October to 8 December 2010. The number of Gentoo Penguins breeding in 2010 was estimated to be 132 321 ± 2 015, the highest number of breeding pairs recorded for this species at the Falkland Islands since the first survey in 1933. The global population of Gentoo Penguins is conservatively estimated to be about 384 000 breeding pairs, of which the Falkland Islands accounts for 34%, probably the largest component of the global population. Annually monitored study colonies accounted for 20% of the total number of Gentoo Penguin breeding pairs at the Falkland Islands in 2010 and proved to be a reliable proxy for archipelago-wide changes in the number of breeding pairs. Recent trends at annually monitored study colonies, combined with archipelago-wide trends, indicate that the number of Gentoo Penguins breeding at the Falkland Islands has increased between 2005 to 2010. However, annual monitoring data also revealed large inter-annual variability in the number of breeding pairs, which makes assessing systematic population changes challenging.

The Bali Aga housing : minimalist and functionalist architecture

Nusantara (Indonesia Archipelago) Architecture is a significant heritage which has been inherited to descendants. Nusantara Architecture is rooted from the existence of culture that spread over the Indonesia archipelago. The culture in each region related to their traditional customs and religions that binding the culture and physic as well as socio-culture of its society. It cannot be denied that the traditional architecture is closed to realm and tactful definitely to interact to the environment. Likewise the Balinese traditional architecture is a substantial treasure which has been inherited and maintained currently. Culture and tradition are adhered in the Tri Hita Karana philosophy, which shows how Balinese balance to their Gods, natures and fellow creatures. The concept implies in the architecture of housing as product of culture. The housing pattern of the Bali Aga villages in Bali Province which has hut forms with linear or compound pattern, it lies naturally from headwater of the mountain to downstream of the sea. The existence of Bali Aga housing stills abide and maintain that defined as reflection of minimalist and functional architecture. Example for this is some observations in the indigenous villages' i.e Pinggan Village, Buahan Village, Julah Village etc. Those housing pattern shows the minimalist concept for living facility and its functions. The discourse of traditional architecture aims to preserve Nusantara architecture which is facing nowadays as a dilemma to be abandoned.

The design of architectural dialect and local identity as Islam strategy in promoting its thought in Indonesia

The design of mosques in Indonesia uses basic principal form of Hindu temple with its roof taking the form of layered pyramid (3, 5, 7). This architectural dialect design approach was effective in promoting Islam in most regions of the Indonesian Archipelago. The detailed explanation about architectural dialect will be elaborated in my full paper. This paper discuss about a friendly approach by using Hindu Building as mosque. It has given a greatly impact to the surrounding society to Accept new religion. Such temple-styled mosques have a history dating back to 1200 AD and form the basic inspiration for mosque designs in all parts of the country. The layered pyramid mosque’s architectural dialect design proves that architecture has played significant role in promoting Islamic doctrines in Indonesia. 85% of the total Indonesian population is Muslim. Based on these statistics, it is widely evident that the use of dialect design as a political strategy by Muslim scholars was effective in introducing and promoting Islamic ideologies in Indonesia. The strategy facilitated psychological acceptance of Islam by the local populations who were initially Hindu believers and were accustomed to the temple. Additionally, the design ensured the peaceful introduction and spread of Islam in the region. Moreover, the fact that the dialect design was based on local identity, combined with local architecture that had highly recognizable building elements (roof and ornament) promoted the spread of Islam in Indonesia.

Use of long-distance migration patterns of an endangered species to inform conservation planning for the world's largest marine protected area

Large marine protected areas (MPAs), each hundreds of thousands of square kilometers, have been set up by governments around the world over the last decade as part of efforts to reduce ocean biodiversity declines, yet their efficacy is hotly debated. The Chagos Archipelago MPA (640,000 km2) (Indian Ocean) lies at the heart of this debate. We conducted the first satellite tracking of a migratory species, the green turtle (Chelonia mydas), within the MPA and assessed the species' use of protected versus unprotected areas. We developed an approach to estimate length of residence within the MPA that may have utility across migratory taxa including tuna and sharks. We recorded the longest ever published migration for an adult cheloniid turtle (3979 km). Seven of 8 tracked individuals migrated to distant foraging grounds, often ≥1000 km outside the MPA. One turtle traveled to foraging grounds within the MPA. Thus, networks of small MPAs, developed synergistically with larger MPAs, may increase the amount of time migrating species spend within protected areas. The MPA will protect turtles during the breeding season and will protect some turtles on their foraging grounds within the MPA and others during the first part of their long-distance postbreeding oceanic migrations. International cooperation will be needed to develop the network of small MPAs needed to supplement the Chagos Archipelago MPA.

Insights into the evolution of a cryptic radiation of bats: dispersal and ecological radiation of Malagasy Miniopterus (Chiroptera: Miniopteridae)

The past decade has seen a proliferation of new species of Miniopterus bats (family Miniopteridae) recognized from Madagascar and the neighboring Comoros archipelago. The interspecific relationships of these taxa, their colonization history, and the evolution of this presumed adaptive radiation have not been sufficiently explored. Using the mitochondrial cytochrome-b gene, we present a phylogeny of the Malagasy members of this widespread Old World genus, based on 218 sequences, of which 82 are new and 136 derived from previous studies. Phylogenetic analyses recovered 18 clades, which divide into five primary lineages: (1) M. griveaudi; (2) M. mahafaliensis, M. sororculus and X3; (3) M. majori, M. gleni and M. griffithsi; (4) M. brachytragos; M. aelleniA, and M. aelleniB; and (5) M. manavi and M. petersoni recovered as sister species, which were in turn linked to a group comprising M. egeri and five genetically distinct populations referred to herein as P3, P4, P5, P6 and P7. Beast analysis indicated that the initial divergence within the Malagasy Miniopterus radiation took place 4.5 Myr; most species diverged between 4 and 2.5 Myr, and a secondary period was between 1.25 and 1 Myr. DNA K2P-distances between recognized taxa ranged from 12.9% to 2.5% and intraspecific variation was less than 1.8%. Of the 18 identified clades, Latin binomials are only associated with 11, which indicates much greater differentiation than currently recognized for Malagasy Miniopterus. These data are placed in a context of the dispersal history of this genus on the island and patterns of ecological diversity.

Reassembling a lost lowland carabid beetle assemblage (Coleoptera) from Kauai, Hawaiian Islands

A late Holocene but prehistoric carabid beetle fauna from the lowland Makauwahi Cave, Kauai, is characterised. Seven extinct species - Blackburnia burneyi, B. cryptipes, B. godzilla, B. menehune, B. mothra, B. ovata and B. rugosa, spp. nov. (tribe Platynini) - represent the first Hawaiian insect species to be newly described from subfossil specimens. Four extant Blackburnia spp. - B. aterrima (Sharp), B. bryophila Liebherr, B. pavida (Sharp), and B. posticata (Sharp) - and three extant species of tribe Bembidiini - Bembidion ignicola Blackburn, B. pacificum Sharp and Tachys oahuensis Blackburn - are also represented. All subfossil fragments are disarticulated, with physical dimensions and cladistic analysis used to associate the major somites - head, prothorax and elytra - for description of the new species. The seven new Makauwahi Cave species support recognition of a lowland area of endemism adjoining Haupu, a low-stature 700m elevation ridgeline in southern Kauai. Four of the extinct Blackburnia are adelphotaxa to extant species currently found at higher elevations in Kauai. Addition of these lowland specialists to the phylogenetic hypothesis undercuts applicability of the taxon cycle for interpreting evolutionary history of these taxa. Two of the extinct species are Kauai representatives in clades that subsequently colonised younger Hawaiian Islands, enhancing support for the progressive biogeographic colonisation of the archipelago by this lineage. And three of the extinct Blackburnia species comprised larger beetles than those of any extant Kauai Blackburnia, consistent with the evolution of island gigantism in the lowland habitats of Kauai.

Unveiling the diversification dynamics of Australasian predaceous diving beetles in the Cenozoic

During the Cenozoic, Australia experienced major climatic shifts that have had dramatic ecological consequences for the modern biota. Mesic tropical ecosystems were progressively restricted to the coasts and replaced by arid-adapted floral and faunal communities. Whilst the role of aridification has been investigated in a wide range of terrestrial lineages, the response of freshwater clades remains poorly investigated. To gain insights into the diversification processes underlying a freshwater radiation, we studied the evolutionary history of the Australasian predaceous diving beetles of the tribe Hydroporini (147 described species). We used an integrative approach including the latest methods in phylogenetics, divergence time estimation, ancestral character state reconstruction, and likelihood-based methods of diversification rate estimation. Phylogenies and dating analyses were reconstructed with molecular data from seven genes (mitochondrial and nuclear) for 117 species (plus 12 outgroups). Robust and well-resolved phylogenies indicate a late Oligocene origin of Australasian Hydroporini. Biogeographic analyses suggest an origin in the East Coast region of Australia, and a dynamic biogeographic scenario implying dispersal events. The group successfully colonized the tropical coastal regions carved by a rampant desertification, and also colonized groundwater ecosystems in Central Australia. Diversification rate analyses suggest that the ongoing aridification of Australia initiated in the Miocene contributed to a major wave of extinctions since the late Pliocene probably attributable to an increasing aridity, range contractions and seasonally disruptions resulting from Quaternary climatic changes. When comparing subterranean and epigean genera, our results show that contrasting mechanisms drove their diversification and therefore current diversity pattern. The Australasian Hydroporini radiation reflects a combination of processes that promoted both diversification, resulting from new ecological opportunities driven by initial aridification, and a subsequent loss of mesic adapted diversity due to increasing aridity.
