Electrically conductive seawater, moving in an ambient magnetic field, generates electromagnetic (EM) variations. Tsunamis are significant contributors to this phenomenon, inducing observable electric and magnetic fluctuations at seafloor and coastal observatories. While understanding of these occurrences in open oceans is robust, knowledge regarding their observation on islands remains limited. This article seeks, through the use of numerical experimentation, to enhance our understanding of tsunami-generated EM (TGEM) variations observed on islands. Utilizing simulations involving conical islands, we identify three key insights regarding EM intensity normalized by the height of incident tsunamis: (i) increased ocean depth surrounding the island amplifies tsunami EM signals, particularly for periods shorter than 20 min; (ii) magnetic field strength at the island is approximately comparable to that observed at the seafloor in the absence of the island when the island radius is smaller than 6 km; and (iii) electric field intensity at the island notably surpasses that observed at the seafloor, especially with smaller island radii (≤ 6 km). Additionally, we establish that employing the ratio of island radius to tsunami wavelength near the island coast facilitates the derivation of empirical functions for this phenomenon. This article is part of the theme issue 'Magnetometric remote sensing of Earth and planetary oceans'. [ABSTRACT FROM AUTHOR]

- Abstract
With the world's transformation to low-carbon energy, island microgrids are developing rapidly because they can save energy and reduce carbon. Island multi-energy microgrids include photovoltaics, a double-fed fan, a battery energy storage system, and AC and DC loads. However, microgrids with high proportions of renewable energy have problems such as large power supply fluctuations and poor power quality. Connection to an AC power grid interconnection will greatly affect their reliability and stability. Firstly, a cascaded neutral point clamped three-level converter (C-NPC) DC interconnection system scheme is proposed. Secondly, the Island C-NPC mathematical models are established, and the flexible multi-mode control of island C-NPCs is proposed. Subsequently, corresponding additional control strategies for DC voltage sharing and AC current sharing among C-NPC modules are designed for the island multienergy microgrid to achieve reliable power supply. Finally, taking an island interconnection project on the east coast of China as a research object, a typical system operation test was performed to verify the good operational characteristics of the system. This research can promote the utilization of clean energy in island regional power grids, achieve carbon reduction, and promote global carbon neutrality. [ABSTRACT FROM AUTHOR]

4. Lifeline Ferries: Existential dimensions of 'essential' mobility.
- Author

Bosbach, Christina
- Abstract
Grounded in an analysis of islanders' ferry mobility between the Isle of Coll and mainland Scotland during the Covid-19 pandemic, this article argues for increased anthropological engagement with the existential dimension of mechanised mobilities. The pandemic restrictions on mobility rested upon the distinction between socio-economically framed 'essential' and existentially framed 'non-essential travel'. However, islanders' agentive navigation of restrictions gave rise to a locally specific regime of im/mobility that emphasised the existential dimension of those mobilities that policymakers understood as a 'lifeline' in a socio-economic sense. To show this, the article applies the concept of existential mobility, developed by Hage, to mechanised mobilities, which remain understudied in anthropology. It argues that thus attending to their existential dimension is crucial to overcome a remaining sedentarist bias in anthropological thinking on mobility, and to avoid unintentionally reproducing governing categories like 'essential' and 'non-essential' in our analyses.

The fauna of Lepidoptera in the Mediterranean is still inadequately documented. As a result, even remotely complete DNA barcode libraries (mt. COI (cytochrome c oxidase 1) gene) are lacking in most areas. This proposed gap is being analyzed for the first time for the fauna of North Cyprus. In the initial phase, 248 morphospecies from 29 families (exclusive Heterocera) were sampled, sequenced and compared with existing DNA reference sequences in the global BOLD database (Barcode of Life Data Systems) via BINs (Barcode Index Numbers). A total of 194 species could be unequivocally assigned to a Linnaean taxon. Additionally, six species previously unidentified in BOLD, as well as fourteen species without reference barcodes, were identified at the species level. Twenty-four of these species were new records for Cyprus. In addition, 25 taxa with new BINs could not be assigned to a valid species due to potential cryptic diversity or the lack of relevant revisions. Furthermore, a few species could not be identified due to barcode sharing and/or potential misidentifications in BOLD. Overall, approximately 20% of the samples could not be identified using the existing DNA barcode libraries, a significant deficit for European standards, which should be addressed as a priority issue in future studies.

Traditionally, festivals have been propitious spaces and times for the renewal of community ties and the strengthening of identity. With the secularization of contemporary societies, the prominence of urban life and the dynamics of individualization and conflict inherent in capitalist cities, this totalizing character has gradually lost its prominence. But this does not mean that festivals do not continue playing, today, a fundamental role in the processes of socialization and reaffirmation of the sense of belonging, besides the social conflicts. The expression of these has been carried out in the urban space, the ideal physical and symbolic setting for the party. This is the case of the Festes de Gràcia de Maó, where the celebration of its great week does not hide the profound differences that exist within local society. [ABSTRACT FROM AUTHOR]

The carnation Dianthus fruticosus L. ssp. fruticosus (Caryophyllaceae) is a range-restricted perennial, endemic plant that grows on cliffs, rocks, ravines, terraces, and boulders on Serifos Island in the Cyclades in the Aegean archipelago (Greece), possessing an impressive, aesthetic blossoming during the dry season. This indigenous carnation of Serifos has attracted the interest of naturalists and scientists. Specimens of this subspecific taxon from the island of Serifos (Greece) were collected during botanical explorations in preindustrial times by the French naturalist Joseph Pitton de Tournefort (1702) and in the late eighteenth century by the English Professor of Botany at the University of Oxford John Sibthorp (1787). Those specimens, documented in relevant publications and labelled with different names (i.e., Caryophyllus Graecus arboreus and Caryophyllus arboreus Seriphius in the early eighteenth century and Dianthus fruticosus in the early nineteenth century), are related to aspects of vegetation history, linking the past to the present and (most probably) to the future. Today, a thorough understanding of the in situ development and functionality of this endemic carnation is still required, as is a framework of its sustainability and management in small-scale insular habitats. The timeless perception of the emblematic wild carnation Dianthus fruticosus ssp. fruticosus, which is still growing on inland and coastal sites of Serifos and neighboring islands in the Cyclades (Greece), is also a reminder that a native plant is often a repository to which local communities may look when crafting their identity.

Historically, the genetic diversity of insular species and populations has generally been considered to be lower with respect to their continental counterparts. In this study, I compare for first time the genetic diversity of two gecko species, Phyllodactylus angelensis and P. magnus , that inhabit contrasting environments in Mexico (island and mainland, respectively). Utilizing genomic data for both species generated through genotyping by sequencing (GBS), I performed paired comparisons of various genetic diversity indices analyzing thousands of single nucleotide polymorphism (SNP) variants. The majority of genetic diversity indices demonstrated very similar values between both species, while the observed heterozygosity and genetic diversity within populations was higher for the insular species. The results do not support the generalized assumption of lower genetic diversity in island species. Key aspects such as the effective population size of founders, gene flow, and shared life histories may be involved in explaining the observed pattern. [ABSTRACT FROM AUTHOR]

Childhood Stunting is a condition of failure to thrive in children under five as a result of chronic malnutrition so that children become too short for their age. Parenting is an important component that should not be disregarded in the pursuit of better nutritional status, since it has an indirect impact on nutritional. This study aims to determine the relationship between family parenting and the incidence of stunting in Simeulue Island Aceh, Indonesia. This study applied a cross-sectional design involving 86 people who were taken by proportional sampling. Chi-square test showed a relationship between permissive parenting and experienced stunting (p-value, 0.001), a relationship between authoritarian parenting and experienced stunting (p-value, 0.000), and a relationship between democratic parenting with experienced stunting (p-value, 0.002). Therefore, it is expected that respondents, namely families of toddlers, will provide good parenting to toddlers so that they will increase the growth and development of toddlers to prevent stunting.

Many coastal and island communities depend on groundwater as the only source of freshwater, making it an invaluable resource. In the Mediterranean region, groundwater resources are highly vulnerable to natural and anthropogenic pressures, such as overexploitation, climate change, seasonal variations in precipitation, and seawater intrusion. Hence, an understanding of hydrogeological processes and groundwater chemistry is a basis for the sustainable management of coastal and island groundwater resources. Vis, a small and remote karst island in the Adriatic Sea, exhibits peculiar geological and hydrogeological settings, resulting in the island's autonomous water supply. The current pumping capacity (maximum of 42 l/s) meets most of the demand, but intensive summer tourism and climate change exert high stress on groundwater resources during the dry season. Consequently, in the last decade, occasional reductions for consumers occurred. Monitoring of in situ physicochemical parameters and groundwater sampling for chemical and isotopic analyses were conducted from 2020 to 2023 at deep borewells, shallow dug wells, and springs. Hydrochemical interpretation indicated that groundwater chemistry was affected primarily by carbonate and sulfate rock dissolution, mixing with seawater, reverse ion exchange, and dedolomitization. The majority of groundwater samples exhibit Ca–HCO
3 hydrochemical facies, followed by Na–Cl and mixed facies. The low percentage of seawater in the mixture indicated that seawater intrusion is not too extensive even during prolonged dry periods, implying a favorable hydrostatic regime with relatively small but sufficient groundwater reserves of the island's aquifers, although the investigated period was characterized by significantly lower precipitation with respect to the 30-year average.

The essay is a comparative analysis of the way in which salvation is presented into three novels dealing with shipwrecks and outcasts: Golding’s Lord of the Flies (1954), Tournier’s Friday, or The Other Island (1967), and Coetzee’s Foe (1986). Through the comparative analysis of three novels of the 20th century, the essay highlights how the shipwreck of the representatives of European civilization on an exotic, deserted and uninhabited island leads to a similar solution, of the impossibility of salvation in the framework of the same civilization. The difference in vision from the happy end feature of the Robinson myth established by Daniel Defoe is self-imposed and proves an acute crisis of modern man’s consciousness, but also an aesthetic awareness of the fact that, a few hundred years away from the establishment of the modern myth, European civilization can no longer feed on its own illusions.

Abstract This study investigates the viability of hybrid photovoltaic (PV), wind, and fuel cell (FC) systems for on‐grid and off‐grid operations for the Ashrayan‐3 housing project in Bangladesh, with an increased focus on sustainable energy solutions. Motivated by the issue of the delivery of proper and sustainable energy services to remote locations, we conducted an extensive analysis of load demand and found that an average daily demand of 46,176.65 kWh exists, with a peak load of 4852.8 kW. In this research, the HOMER software has been used to make a simulation of five different hybrid system configurations with differing mixes of renewable technologies. From the analyses, the systems based 100% on renewable resources suffer more initial capital costs, with a total net present cost increase of up to 20%, in comparison to conventional systems. On the other hand, the systems give much lower operational costs and cost of energies (COEs) of a minimum of $0.0253/kWh, reported from the on‐grid PV‐based system. On the other hand, the off‐grid PV–FC–wind turbine system showed a COE of $0.286/kWh, along with a decrease in CO2 emissions by about 15,000 kg/year, showing a 30% decrease, compared with on‐grid systems. The results form a basis for the conclusion that such hybrid renewable energy systems are both economically and environmentally feasible. They can reduce COEs by up to 70% in off‐grid systems. This proves that the quality of life and energy security in developing regions will be highly increased, supporting the goals of sustainable development.

With the successive launch of high-resolution Synthetic Aperture Radar (SAR) satellites, conducting all-weather, all-time high-precision observation of island regions with variable weather conditions has become feasible. As a key preprocessing step in various remote sensing applications, orthorectification relies on high-precision control points to correct the geometric positioning errors of SAR images. However, obtaining artificial control points that meet SAR correction requirements in island areas is costly and risky. To address this challenge, this study first proposes a rapid registration algorithm for optical and SAR heterogeneous images, and then automatically extracts control points based on an optical reference base map, achieving orthorectification of SAR images in island regions. The proposed registration algorithm consists of two stages: constructing dense common features of heterogeneous images; performing pixel-by-pixel matching on the down-sampled features, to avoid the issue of low repeatability of feature points in heterogeneous images. To reduce the matching complexity, a land sea segmentation mask is introduced to limit the search range. Subsequently, local fine matching is applied to the preliminary matched points to reduce inaccuracies introduced by down-sampling. Meanwhile, uniformly sampled coastline points are introduced to enhance the uniformity of the matching results, and orthorectified images are generated through a piecewise linear transformation model, ensuring the overall correction accuracy in sparse island areas. This algorithm performs excellently on the high-resolution SAR images of multiple scenes in island regions, with an average positioning error of 3.2 m and a complete scene correction time of only 17.3 s, both these values are superior to various existing advanced heterogeneous registration and correction algorithms, demonstrating the great potential of the proposed algorithm in engineering applications.

Coiba National Park is an offshore region on the Pacific side of Panama, which hosts several endemic species of animals and plants. It was declared a UNESCO World Heritage Site in 2005. Despite the title awarded to the Park, knowledge about basic elements of its biodiversity are still lacking, which are of vital relevance for management and conservation policies. For instance, until now, no study had ever monitored the araneofauna diversity of the Park.Here, we provide the first checklist of spider species in Coiba National Park, including the main island and several surrounding islands. We sampled during several field trips carried out from August 2021 to August 2023. We identified at least 152 species (98 genera and 30 families) and we report three new spiders species for Panama, namely Ctenus nigrolineatus Berland (1913), Chapoda gitae Zhang & Maddison (2012) and Sarinda nigra Peckham & Peckham (1892). We discuss the implications of our results and recommend future lines of work that include DNA barcoding, monitoring of population and community dynamics, plus linkage of climatic data from the newly-installed meteorological station on the Island.

Insects geographically separated into island and mainland populations often exhibit phenotypic variations, a phenomenon known as insular conditions. These conditions can lead to rapid evolutionary changes that affect the morphological characteristics of mosquito vectors. Nevertheless, studies that specifically examine phenotype differences between island and mainland mosquito populations have been limited. In this study, wing variation in size and shape was investigated using the geometric morphometric (GM) technique in two dominant mosquito vectors, Aedes albopictus and Armigeres subalbatus, in the Ranong and Trat archipelagos of Thailand. Significant differences in average wing centroid size (CS) were found in 6 out of 15 population pairs for Ae. albopictus (p < 0.05) and in 5 population pairs for Ar. subalbatus (p < 0.05). After removing the allometric effect, canonical variate analyses (CVA) based on wing shape analysis revealed overlap across all populations for both Ae. albopictus and Ar. subalbatus. However, the statistical analysis indicated that Ar. subalbatus exhibited wing shape differences across all populations (p < 0.05), and most Ae. albopictus populations also displayed distinct wing shapes (p < 0.05), except for the populations from Chang Island and the mainland of Ranong, which showed no significant differences (p > 0.05). These findings enhance our understanding of mosquito adaptability in island regions and provide valuable data for the surveillance and monitoring of vector evolution. [ABSTRACT FROM AUTHOR]

The World's one of largest inhabited river-made island Majuli, developed in response to depositional processes of large sediment load carried by the Bramhaputra River and Subhansari River from the Himalayan hinterland. But, for decades it has been going through a significant rate of erosion, which is severely threatening the existence of the island and its rich cultural heritage. These erosional processes result in exposure to island depositional records and provide an opportunity to study these sedimentary deposits. This paleo depositional record is very well analysed by adopting the methodology of facies identification and their relationship diagram. A total of 18 exposed outcrop sections are studied with detailed sedimentological documentation, facies identification and symbols assigned to facies. Then calculations and tabulations are carried out for Facies Relationship Diagram (FRD) along with the construction of the sequence model, which provides a lateral and vertical lithofacies association developed in the entire island sequentially. On the basis of validation of obtained data through field survey and analysis of more vertical profiles, we study the correlation between existing bank erosion and dominated sedimentary facies at Majuli Island. This analysis results in two facies sequences: one mud-dominated and the other sand-dominated facies. The Massive Mud and Massive Sand beds are represented as the main facies between these two sequences. Therefore, mud-dominated sequence represents the Flood Plain deposit, whereas the sand-dominated sequence represents Bar and Channel deposits. This study also reveals that sedimentary sequences developed by the Bramhaputra River are mud dominated, while that of the Subhansiri River is both mud and sand sequences. This reflects the differential source to sink transport of sediments, as the Bramhaputra River carries sediment load for a longer distance than the Subhanshiri River. This study also reveals that areas of sand-dominated facies show higher erosion than mud-dominated facies. Therefore, the sedimentary record of the Subhansiri River is more vulnerable to erosion.

We present a multiproxy analysis of a sediment core from Freshwater Pond, Barbuda, one of just a few inland paleoenvironmental records from the Lesser Antilles. Our results shed light on the relative contributions of climate variability and Pre- and Post-Columbian human activities to vegetation and fire dynamics on Barbuda. The presence of macroscopic charcoal and pollen of ethnobotanically-useful and disturbance-indicator plant taxa in the sediment record suggests that Pre-Columbian subsistence activities occurred within a few kilometers of the pond between ~150 BCE and ~1250 CE. Our record extends anthropogenic fires back into the early Ceramic (500 BCE–1500 CE) and possibly late Archaic Ages (3000–500 BCE) adding evidence to the timing of arrival of the island's earliest inhabitants. The history of island-wide biomass burning inferred from microscopic charcoal fragments showed heightened fire activity between ~540 and ~1610 CE followed by a period of quiescence that reflected the transition from Pre- to Post-Columbian land-use practices associated with European colonization of the region. The British established a permanent settlement on Barbuda in the 1660s, but given Barbuda's unsuitability for large-scale agriculture, timber harvesting, small-scale farming, and livestock rearing, activities that left no detectable charcoal footprints likely dominated post-colonial land use. The lack of any clear correspondence between the reconstructed histories of fire and effective moisture at Freshwater Pond supports the idea that Late-Holocene fire activity on Barbuda was driven primarily by human activity.

This study investigates the viability of hybrid photovoltaic (PV), wind, and fuel cell (FC) systems for on‐grid and off‐grid operations for the Ashrayan‐3 housing project in Bangladesh, with an increased focus on sustainable energy solutions. Motivated by the issue of the delivery of proper and sustainable energy services to remote locations, we conducted an extensive analysis of load demand and found that an average daily demand of 46,176.65 kWh exists, with a peak load of 4852.8 kW. In this research, the HOMER software has been used to make a simulation of five different hybrid system configurations with differing mixes of renewable technologies. From the analyses, the systems based 100% on renewable resources suffer more initial capital costs, with a total net present cost increase of up to 20%, in comparison to conventional systems. On the other hand, the systems give much lower operational costs and cost of energies (COEs) of a minimum of $0.0253/kWh, reported from the on‐grid PV‐based system. On the other hand, the off‐grid PV–FC–wind turbine system showed a COE of $0.286/kWh, along with a decrease in CO2 emissions by about 15,000 kg/year, showing a 30% decrease, compared with on‐grid systems. The results form a basis for the conclusion that such hybrid renewable energy systems are both economically and environmentally feasible. They can reduce COEs by up to 70% in off‐grid systems. This proves that the quality of life and energy security in developing regions will be highly increased, supporting the goals of sustainable development. [ABSTRACT FROM AUTHOR]

Unifying research and conservation objectives with the needs of local populations demands a profound understanding of the field. This perspective provides a brief policy and social‐cultural context for the conservation of endangered sea turtles in São Tomé and Príncipe, Central Africa. It is illustrated by initiatives implemented from the 90s to the 2000s and complemented by a community‐based intervention on Príncipe Island (2010–2014). The intervention focused on awareness‐raising, economic‐alternatives, capacity‐building, and surveillances to deter poaching, collect scientific data, and increase outreach. It contributed to reduce sea turtle exploitation, train local conservationists, and increase awareness to economic alternatives. Securing stakeholders' support is vital for success, and endeavors like this provide a cost‐effective approach, aligning biodiversity conservation strategies with local values and aspirations. Overall, this perspective underscores that failure to collaborate with those involved in wildlife subsistence livelihoods often results in delays and setbacks in reducing exploitation, while modest investments in local stewardship can efficiently improve ecosystems and human well‐being.

26. TWO GIRLS BY THE SEA: Reflections on the role of the island in the Faroese film Dreams by the Sea.

Gaini, Firouz
- Abstract
This essay discusses island films as a possible cinematographic genre based on the case of the Faroese feature film Dreams by the Sea (Sakaris Stórá, 2017). It examines the role and meaning - as focus and locus - of the island in the award-winning Faroese production, which takes viewers to a small remote village in the northwestern Atlantic island community. Dreams by the Sea is about young lives, islandness, and future dreams. New Faroese cinema aims to de-exoticise the islands and to picture and narrate the stories that too often are - intentionally or unintentionally - kept out of the public eye. This essay is based on my extensive ethnographic research among Faroese youngsters since the beginning of the 21st century with special focus on the film landscape of contemporary island youth. The main findings of the essay were presented at the international Islands and audiovisual media conference organised in Torshavn, the Faroe Islands, 26-28 June (2024). [ABSTRACT FROM AUTHOR]

Homestead windbreaks are used on the Ryukyu Islands to protect houses from the tidal water blowing from the sea, strong typhoons in the summer, and monsoonal winds in the winter. The homestead windbreak landscape is believed to have been established approximately 300 years ago in the Ryukyu Kingdom. Garcinia subelliptica (Fukugi in Japanese) was dominant in this windbreak landscape. These windbreaks vanished on several islands soon after World War II. Many trees were burned during the war and removed to extend village roads in rural and recent resort development projects. This study surveyed the present spatial distribution of the remaining homestead windbreaks and conducted a tree inventory survey. We recorded the location and characteristics of trees damaged by the powerful typhoon and tentatively explored the causes of tree and house damage through a case study of Yonaguni Island, where one of the world's biggest typhoons occurred. Homestead windbreaks facing the wind direction, tree characters of cavities, unsound branching, and combined tree trunks were the significant factors contributing to tree damage. The remnant homestead windbreak belts in Yonaguni Island were fragmented and not continuous and may not offer consistent wind protection since there are open gaps between the sections. It suggests windbreaks should be replanted in the direction of the wind, and regular checks of tree health and tree structure are needed to reduce typhoon damage. The results are used to propose guidelines for windbreak management and conservation. [ABSTRACT FROM AUTHOR]

SPIDERS ,NATIONAL parks & reserves ,WORLD Heritage Sites - Abstract
Background: Coiba National Park is an offshore region on the Pacific side of Panama, which hosts several endemic species of animals and plants. It was declared a UNESCO World Heritage Site in 2005. Despite the title awarded to the Park, knowledge about basic elements of its biodiversity are still lacking, which are of vital relevance for management and conservation policies. For instance, until now, no study had ever monitored the araneofauna diversity of the Park. New information: Here, we provide the first checklist of spider species in Coiba National Park, including the main island and several surrounding islands. We sampled during several field trips carried out from August 2021 to August 2023. We identified at least 152 species (98 genera and 30 families) and we report three new spiders species for Panama, namely Ctenus nigrolineatus Berland (1913), Chapoda gitae Zhang & Maddison (2012) and Sarinda nigra Peckham & Peckham (1892). We discuss the implications of our results and recommend future lines of work that include DNA barcoding, monitoring of population and community dynamics, plus linkage of climatic data from the newly-installed meteorological station on the Island.

The conceptualization of insularity in the context of islands has been widely studied and debated, encompassing both geographical and identity aspects. The academic discussion on the definition of insularity and isolation in the context of islands remains a current topic, along with the economic, social, legal and environmental challenges faced by insular regions. This study aims to deepen the conceptual framework of insularity and structure its issues from various scientific perspectives through quantitative bibliometric analysis. Key focus areas and research gaps have been identified, including the need for enhanced economic policies, better marine resource management, more comprehensive urban development research and improved data on social and political issues. The conclusions emphasize the importance of prioritizing intervention areas and specific policies to address the unique challenges faced by insular regions in terms of sustainable development.

ABSTRACTThe evolution and future trajectory of island shorelines, amidst global climate change, are of increasing concern to governments, communities and researchers worldwide. However, the field of island studies is often hampered by a lack of data and inconsistent methodologies, leading to an inadequate understanding of the processes driving shoreline changes on islands within the context of climate change. This research aims to bridge this gap by analyzing islands in Southeast Asia, the Indian Ocean and the Mediterranean Sea from 1990 to 2020 using remote sensing. Of over 13,000 islands examined, approximately 12% experienced significant shifts in shoreline positions. The total shoreline length of these islands approaches 200,000 km, with 7.57% showing signs of landward erosion and 6.05% expanding seaward. Human activities, particularly reclamation and land filling, were identified as primary drivers of local shoreline transformations, while natural factors have a comparatively minor impact. Moreover, the ongoing rise in sea levels is identified as an exacerbating factor for coastal erosion rather than the primary cause. Drawing from these findings, we propose several adaptive measures for islands in response to climate change. Taken together, this research provides comprehensive data and a basis for decision-making for sustainable development of island territories.

With the world’s transformation to low-carbon energy, island microgrids are developing rapidly because they can save energy and reduce carbon. Island multi-energy microgrids include photovoltaics, a double-fed fan, a battery energy storage system, and AC and DC loads. However, microgrids with high proportions of renewable energy have problems such as large power supply fluctuations and poor power quality. Connection to an AC power grid interconnection will greatly affect their reliability and stability. Firstly, a cascaded neutral point clamped three-level converter (C-NPC) DC interconnection system scheme is proposed. Secondly, the Island C-NPC mathematical models are established, and the flexible multi-mode control of island C-NPCs is proposed. Subsequently, corresponding additional control strategies for DC voltage sharing and AC current sharing among C-NPC modules are designed for the island multienergy microgrid to achieve reliable power supply. Finally, taking an island interconnection project on the east coast of China as a research object, a typical system operation test was performed to verify the good operational characteristics of the system. This research can promote the utilization of clean energy in island regional power grids, achieve carbon reduction, and promote global carbon neutrality.

On the island of Fuvahmulah, Maldives, community members have learned to co-exist with resident tiger sharks. Rapidly becoming a premier destination for shark tourism, Fuvahmulah demonstrates a novel circumstance for how this often-polarizing industry can both bolster the local economy and strengthen shark conservation efforts. Focusing on personal storytelling, this project delivers a 5-part video series and interactive website featuring video portraitures of locals involved in and impacted by the industry. This anecdotal multimedia approach helps examine the grey areas of shark tourism while addressing ways to ensure its sustainability and longevity on the island.You can see the media created for this project here: https://miyaru.org/stories

My PhD thesis focuses on the attachment of Tuvaluan immigrants to their homeland and the host land. It is motivated to understand the effect of migration on their place attachment and belonging, navigation across the island and ocean, and thoughts on climate change that threatens Tuvalu's continuity. I use place attachment theory because it is a useful theoretical lens to explore Tuvaluans' interrelationship with the homeland and the host land post-migration. I am particularly interested in understanding whether Tuvaluans' attachment to the homeland decays or persists post-migration and how they process their sense of belonging to New Zealand. The research uses mixed methods: a survey, Talanoa conversations (a Pacific storytelling approach) and participant observation from a three-month field trip to New Zealand in September - November 2019. My main findings indicate that the Tuvaluan participants keep a strong attachment to Tuvalu and develop an attachment to New Zealand. Attachment to both places does not exist in tension. Yet, certain variations reveal different degrees of personal, sociocultural and environmental struggles among some participants. The participants' attachment to Tuvalu is emotional, sociocultural, and nostalgic. Meanwhile, their attachment to New Zealand is mostly based on a functional place dependence, making Tuvalu the "home" and New Zealand the "house". Nevertheless, some participants' decaying attachment to Tuvalu becomes apparent due to socioeconomic and environmental pressures. Similarly, although New Zealand becomes the house or the home-away-from-home that provides safety and prospects, the participants experience socioeconomic and geographic challenges. These pressures and challenges in both loci lead to the emergence of solastalgia, a sense of alienation and stress. The research stresses that Tuvaluans are not mere future environmental refugees. Instead, they move and carry intricate transnational ties with the homeland they wish to preserve, embrace the alternative routes, and express their place attachment through social, cultural, and relational patterns.

In my paper I point out that the study of literary utopias has been and still is a constant focus on my scientific research. It has accompanied me in different historical and political contexts, helping in analysing and interpreting their complexity. The metaphor I use is that of Utopia as a tree with deep roots from which many branches spread out. In my first book on this topic, I suggested that Utopia could be considered on the whole as a literary genre, characterized by a continuous metamorphosis over time and space. Within such a theoretical framework, I addressed how a variety of utopian main themes, i.e. the journey, the island, and the dream, have been treated in pillars of utopian English literature. Eventually, what fascinated me is that Utopia allowed and still allows me to look at major problems and questions of my contemporary time taking a “lateral” perspective and envisaging new, usually unexpected, political horizons.

Abstract Background Respiratory viral illnesses among children are a prominent cause of morbidity and mortality in the developing world. The aim of this study is to understand the seasonal pattern and surge of respiratory viruses among the Nicobarese tribe. Methods Respiratory specimens were collected from both ARI and SARI cases attended the BJR district hospital in Car Nicobar Island, India, between 2021 and 2022. Respiratory viruses were identified from the specimens by using the qRT-PCR assay. Meteorological parameters were collected and evaluated using Microsoft Excel and SPSS 21. The significant association between the surge of respiratory viruses and each climatic parameter was evaluated. Results In this hospital-based cross-sectional study, 471 ILI cases were enrolled, and 209 of these were positive for respiratory viral infections. Of these respiratory virus infections, 201 (96.2%) were infected with a single respiratory virus infection, and 8 (3.8%) had mixed viral infections. Fever, cough, and chills were the most common symptoms of respiratory illness among this indigenous population. There was a significant link between respiratory viruses and influenza-like illness in children (below 5 years and 6 to 15 years). Conclusion This prevalence study revealed that viral respiratory infections were more common in children than adults. Among these respiratory viruses, respiratory syncytial virus A (RSV) and influenza B virus were predominantly reported among tribal children up to age five years. In the year 2021, these viruses were recorded frequently during the winter season. Climate factors such as high humidity, high precipitation, moderate temperature, and moderate rainfall are found to be correlated with respiratory viral infections. This study implicates important information for preventing a further outbreak of respiratory viral infections in Car Nicobar Island.

The two East Asian subtropical–tropical noctuoid moths, Nyctemera adversata (Schaller, 1788) (Erebidae: Arctiinae) and Dictyestra dissectus (Walker, 1865) (Noctuidae: Noctuinae), are newly recorded in the Russian Far East on an extreme long distance to the north from their known localities in the neighboring countries. They were collected on the small Rikord Island in the Peter the Great Gulf after the period of strong southern wind associated with Typhoon Chaba. Data on the general distribution and bionomics of these species are given. This founding, along with other similar discoveries, is consistent with the current trend of global climate warming and indicates a northward expansion of the ranges of southern species in the Sea of Japan/East Sea region. Large migratory moths effectively use powerful air currents to move long distances, including over the sea, while small coastal islands can be used by them as intermediate sites and/or for possible establishing of invasive populations.

Island is a special area with natural and socio-economic vulnerability, which to some extent restricts the livelihood strategy choices and development of island residents. Relying on the rich tourism resources of the island, the tourism industry has become an important source of livelihood for farmers in the villages around the scenic spots in the island. However, The difference of tourism resource endowment of different villages will inevitably affect the livelihood capital level of farmers in different villages. This paper takes 15 villages of South Changshan Island and North Changshan Island of Changdao as the research area, constructs the livelihood capital evaluation index system, measures the total livelihood capital index of Yujiale farmers in the research area, analyzes the spatial distribution pattern and agglomeration characteristics of the total livelihood capital index, and put forward suggestions to improve the livelihood capital level of Yujiale farmers to promote the sustainable livelihood development of island farmers.

The islands of Brittany provide unique ecosystems for ticks and tick-borne diseases owing to their oceanic climate, influencing interactions among ticks, hosts, and pathogens. We conducted a preliminary investigation on Belle-Île-en-Mer, an island off the Atlantic coast of Brittany in western France, to assess the prevalence of questing adult ticks and associated human pathogenic bacteria. Dermacentor spp. were found to dominate the tick population (61 %): 23 % Dermacentor reticulatus and 77 % D. marginatus. Haemaphysalis punctata (27 %) was also prevalent on the island, and Ixodes ricinus (12 %) was detected for the first time on Belle-Île-en-Mer. Both Dermacentor species harbored either Rickettsia slovaca (24 %) or Rickettsia raoultii (20 %), whereas I. ricinus carried Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum but not Borrelia miyamotoi or Neoehrlichia mikurensis. Detection of two potentially pathogenic species in the B. burgdorferi sensu lato complex, B. afzelii and B. lusitaniae, along with A. phagocytophilum underscores the current risk of Lyme borreliosis and anaplasmosis. The high prevalence of Rickettsia infection in Dermacentor indicates an additional risk of human rickettsioses.

Oceanic islands have been recognized as natural laboratories in which to study a great variety of evolutionary processes. One such process is evolutionary radiations, the diversification of a single ancestor into a number of species that inhabit different environments and differ in the traits that allow them to exploit those environments. The factors that drive evolutionary radiations have been studied for decades in charismatic organisms such as birds or lizards, but are lacking in lichen-forming fungi, despite recent reports of some lineages showing diversification patterns congruent with radiation. Here we propose the Ramalina decipiens group as a model system in which to carry out such studies. This group is currently thought to be comprised of five saxicolous species, all of them endemic to the Macaronesian region (the Azores, Madeira, Selvagens, Canary and Cape Verde islands). Three species are single-island endemics (a rare geographic distribution pattern in lichens), whereas two are widespread and show extreme morphological variation. The latter are suspected to harbor unrecognized species-level lineages. In order to use the Ramalina decipiens group as a model system it is necessary to resolve the group's phylogeny and to clarify its species boundaries. In this study we attempt to do so following an integrative taxonomy approach. We constructed a phylogenetic tree based on six molecular markers, four of which are newly developed and generated competing species hypotheses based on molecular (species discovery strategies based on both single locus and multilocus datasets) and phenotypic data (unsupervised clustering algorithms based on morphology, secondary chemistry and geographic origin). We found that taxonomic diversity in the Ramalina decipiens group has been highly underestimated in previous studies. In consequence, we describe six new species, most of them single-island endemics and provide a key to the group. Phylogenetic relationships among species have been reconstructed with almost full support which, coupled with the endemic character of the group, makes it an excellent system for the study of island radiations in lichen-forming fungi.

To improve precipitation estimation and forecasting, it is important to have a thorough understanding of the regional variability of raindrop size distribution (DSD) characteristics. This study aims to investigate the differences in DSDs between island and inland areas along the South China coastline, using observations from four disdrometers. The results of the study reveal that convective precipitation is the main contributor to summer rainfall in South China, with regional variations in DSD. The eastern stations (Shangchuan Island and Yangjiang) exhibit a higher concentration of large raindrops and a lower concentration of small raindrops compared to the western stations (Weizhou Island and Fangchenggang), which have more small raindrops. Additionally, the inland stations have a higher number of large raindrops (with a diameter greater than 3mm) compared to the island stations. The study also discusses the differences in environmental conditions that contribute to these variations. It is found that the warm cloud depth at the eastern (inland) stations is thicker than at the western (island) stations, indicating a longer pathway for raindrops to fall towards the ground and an enhanced collisional-coalescence process for raindrop growth. Furthermore, the shape-slope (μ -L) and radar reflectivity-rain rate (Z-R) relationships for the four stations also exhibit differences. Overall, this study provides a more comprehensive understanding of the regional variability of precipitation microphysics in South China. [ABSTRACT FROM AUTHOR]

- Abstract
This study has estimated the missing values of minimum temperature, maximum temperature and rainfall records of longer lengths, respectively, from 1994 to 1996 in Hatiya and 2000–2003 in Sandwip islands of the Bay of Bengal with harmonic regression analysis to realize the past climate. The work has provided past climate of records, which have justified with the mean absolute error, root mean squared error and skill score respectively 1.50, 2.00 and 0.84 for minimum temperature, 1.66, 2.10 and 0.48 for maximum temperature, and 8.60, 14.69 and –0.43 for rainfall for the stations with known records. The mean of the two estimations varies respectively for temperature and rainfall from –0.69 to 0.64°C and –0.36 to 4.79 mm, where one estimation is done with the proposed harmonic analysis and another estimation has been done with inverse-distance-weighting technique for the stations with missing records. The study is advantageous because it uses data from its own station on the island rather than data from neighbouring stations on the continent. It has avoided the probability of mixing up the continental climate with the climate of the island and vice versa. Hence, the estimations provided are spatially unbiased and meaningful past climate.
