Abstract:

AbstractThe prevalence of canine Dirofilaria infection in Maio Island (Cape Verde) was analysed by serology, morphological and molecular identification of the parasite species. Blood and sera were collected from 150 dogs and 80 cats aged over 6 months from various localities of the island. DNA was extracted from blood and samples were screened by polymerase chain reaction (PCR) using microfilaria-specific primers. No Dirofilaria immitis was found in dogs while D. repens microfilariae were found in 5.3% of dogs and 6% were positive by PCR. The species identity was confirmed by sequencing of PCR products, which showed almost 100% homology with D. repens European sequences published in GenBank. No difference in Dirofilaria infection was observed between males and females or in dogs with different weights. However, older dogs and those from the western part of Maio Island were more frequently infected. No Dirofilaria was found in cats. This study represents the first evidence of D. repens in Cape Verde (West Africa) and highlights the need for implementing control measures and for a better surveillance of dirofilariosis in Africa.

Abstract:

Previous studies revealed high levels of antimicrobial resistance (AMR) in loggerhead sea turtles (Caretta caretta), describing this species as prime reservoir of antimicrobial-resistant bacteria. This study aimed to characterise, for the first time, the AMR and virulence profiles of Gram-negative bacteria isolated from 33 nesting loggerhead turtles of the island of Maio, Cape Verde. Cloacal, oral, and egg content swab samples (n = 99) were collected and analysed using conventional bacteriological techniques. Shewanella putrefaciens, Morganella morganii, and Vibrio alginolyticus were isolated from the samples under study. The isolates obtained from this loggerhead subpopulation (North-East Atlantic) revealed lower levels of AMR, compared with the results of studies performed in other subpopulations (e.g., Mediterranean). However, the detection of resistance to carbapenems and multiple antimicrobial resistance indices higher than 0.20, raises concern about the potential association of these animals to points of high antimicrobial exposure. Furthermore, virulence phenotypic characterisation revealed that the isolates presented complex virulence profiles, including the ability to produce biofilms. Finally, due to their pathogenic potential, and considering the evidence of illegal consumption of turtle-related products on the island of Maio, the identified bacteria may represent a significant threat to public health.

Abstract:

Abstract We describe the main reproductive characteristics (laying date, egg size, hatchling mass, and breeding success), chick growth, and patterns of provisioning in Lesser Noddies (Anous tenuirostris) on Aride Island, Seychelles, 1995–2002. The bulk of the population laid eggs between late May and late June in most years. Both hatching and fledging success varied significantly between years, with fledging success (2–92%) more variable than hatching success (28–91%). Productivity of less than 0.10 chicks per breeding pair occurred in 25% of the years. In 2001, egg volume did not differ significantly between hatched and unhatched eggs. Chick mass at hatching was significantly correlated with an egg volume index, but there were no correlations between egg size and either hatching date or linear growth rate. Around 40% of the Lesser Noddy chicks were fed at dusk. Chicks aged 0–5 and 6–10 days received significantly less food than older chicks. There was evidence of daily and stochastic variation in the foraging success of individual birds. Comparing similar studies, chicks of Lesser Noddies and Sooty Terns (Sterna fuscata) appeared more resistant to fluctuating food supplies than those of Roseate Terns (Sterna dougallii), indicating that, in tropical seas, slow growth and foraging farther offshore are more advantageous than faster growth and inshore feeding. Datas de Postura, Alimentação dos Filhotes e Sucesso Reprodutivo de Anous tenuirostris na Ilha de Aride, Seychelles Resumo. Neste estudo descrevemos as principais características da biologia reprodutiva (datas de postura, tamanho dos ovos, peso dos filhotes ao nascerem e sucesso reprodutivo), crescimento e padrões de alimentação dos filhotes em Tinhosa-de-barrete, Anous tenuirostris, na ilha de Aride, Seychelles, 1995–2002. Na maioria dos anos a postura ocorreu entre o fim de Maio e o fim de Junho. O sucesso de eclosão e o sucesso de sobrevivência das crias variaram significativamente entre anos, apresentando o sucesso de sobrevivência (2–92%) uma maior variação do que o sucesso de eclosão (28–91%). Uma produtividade inferior a 0,10 crias por casal reprodutor ocorreu em 25% dos anos. Em 2001, o volume dos ovos que eclodiram não diferiu significativamente do volume dos ovos que não eclodiram. O peso dos filhotes ao nascerem apresentou uma correlação significativa com o índice de volume dos ovos, mas não se obtiveram correlações entre o tamanho dos ovos e, a data de eclosão e a taxa de crescimento linear dos filhotes. Cerca de 40% dos filhotes de Tinhosa-de-barrete foram alimentados ao anoitecer. Os filhotes com idades entre 0–5 e 6–10 dias receberam significativamente menos alimento do que os filhotes mais velhos. Foram observadas variações diárias e estocásticas no sucesso de alimentação dos indivíduos. A comparação do presente estudo com estudos semelhantes, sugere que as crias de A. tenuirostris e de Sterna fuscata sejam mais resistentes a flutuações na disponibilidade de alimento do que as crias de Sterna dougallii. Isto indica que, em mares tropicais, uma menor taxa de crescimento e uma alimentação em zonas pelágicas são estratégias mais vantajosas do que uma taxa de crescimento rápida e alimentação em zonas costeiras.

Abstract:

This article explores the prerequisites for sustainable development of island territories of the Gulf of Peter the Great that retained their autonomy from continental Vladivostok – AskoldIsland, Popov Island, Reyneke Island, Rikord Island, Putyanin Island. A brief overview is provided on the development of islands in prerevolutionary and Soviet period, as well as at the turn of the XX – XXI centuries. It is noted, that the initial period of islands territorial development (late XIX – early XX centuries) is characterized with sustainable natural resource management based on consideration of the local landscape, natural and climatic conditions. Computer modeling of the annual course of wind and insolation regime of island territories is conducted for elaboration of the advanced models of sustainable natural resource management. This allowed determining comfort and discomfort landscape areas of the indicated islands for the three main seasons – winter, spring-summer, and summer. Typical terrain contributes to localization of the comfort and discomfort zones. At the same time, comfort and discomfort zone would be specific for each of the three seasons, which should be considered in arranging various types of recreation activities. Based on the results of studying the peculiarities of socioeconomic development of the islands and their landscape-climatic specificity, the author highlights three groups of islands and suggests models of sustainable development for each group: 1) Model of full-scale economic-recreational development with restoration of the collapsed ecological framework  (Popov Island and Putyanin Island); 2) Model of autonomous development with restoration of the collapsed ecological framework (Reyneke Islan); 3) Model of economical development (Askold Island, Rikord Island). The author develops the schemes of territorial development of the islands, and suggests projects on formation of sustainable environment of rural localities and tourist routs.

Abstract:

This work analyses the possibility of extracting energy from the ocean waves around the Leeward Islands of Cabo-Verde. This study was based on 31 years of wave and wind data, obtained through the SOWFIA - Streamlining of Ocean Wave Farm Impact Assessment, at 16° N-24° W. Then, the SWAN - Simulating Waves Nearshores - was used to perform the wave transformations to the shore. As the number of waves is very high, the cluster analysis and the Non-Parametric Wilcoxon Test were used to reduce the computing time by SWAN. The results pointed to the South of these islands and the East Coast of Maio island as the best locations for wave energy extraction. The use of the power matrix of some commercial devices that are available, such as Wave Dragon (7 MW), Pelamis (750 kW) and AquaBuoy (250 kW), allowed to estimate the best devices scale factors that leads to their best Capacity Factor (CF), at the target regions. Thus, the Wave Dragon is the most indicated device (CF=71%), at the scale of 0.3, followed by AquaBuoy scaled by 0.4 (CF=57%) and Pelamis scaled by 0.5, with CF=26%. However, in a natural scale, AquaBuoy is the most efficient device (CF = 18.8%) in comparison to the Wave Dragon (CF=17%) and Pelamis (CF=15%). AquaBuoy presented the best cost-benefit ratio (C/B = 0.135 USD/kWh) followed by Wave Dragon (C/B= 0.235 USD/kWh) and Pelamis (C/B = 0.390 USD/kWh). The limitation of the number of Wave Energy Converters to implement the wave power plant affects negatively the cost of its investment.©2019. CBIORE-IJRED.

Abstract:

There are relatively few studies on snake fauna from coastal islands of the State of São Paulo (SSP), Southeastern Brazil and the number of species housed in Brazilian institutional zoological collections is relatively limited. In Brazil, for the first time, a snake inventory for eighteen islands of coastal SSP is presented. Here we record data from sampling on eleven islands as well information on vouchered species in the main herpetological collections. Thirty-six species from four families: one Boidae, thirty Colubridae, one Elapidae and four Viperidae from eighteen islands are listed as well as the thirteen new island records for snakes. Relative abundance categories were used for species rarity: common, infrequent and rare; 44.4% of the snakes with voucher specimens were considered rare. The most common species in twelve of the eighteen islands was Micrurus corallinus; in eleven of the eighteen islands were Bothrops jararaca and Liophis miliaris; in ten of the eighteen islands were B. jararacussu and Chironius bicarinatus. The most common snake species on coastal islands were Micrurus corallinus which was found in twelve of the eighteen islands, followed by Bothrops jararaca and Liophis miliaris found on eleven of the eighteen islands and B. jararacussu and Chironius bicarinatus which were found in ten of the eighteen islands studied. There are seven new records of snake species for Cardoso Island (25° 05’ S and 047° 59’ W): C. bicarinatus, C. multiventris, Dipsas petersi, Echinanthera bilineata, E. cephalostriata, Helicops carinicaudus and Xenodon neuwiedii; three new records for Comprida Island (24° 54’ S and 47° 48’ W): B. jararacussu, C. bicarinatus and H. carinicaudus; one for Anchieta Island (23° 32’ S and 045° 03’ W): Spilotes pullatus; one for Couves Island (23° 25’ S and 44° 52’ W): L. miliaris; one for Porcos Island (23° 23’ S and 44° 54’ W), B. jararaca. The endemic species B. alcatraz from Alcatrazes Island and B. insularis from Queimada Grande Island are considered endangered species by IUCN. Snake fauna on Monte de Trigo Island are extinct. The fragility of insular snake fauna needs more attention for environmental conservation, since 52.0% of snake species preys on amphibians, highlighting the importance of forest conservation.

Abstract:

The islands of Komodo National Park in the Wallacea region are the habitats of Komodo dragon (Varanus komodoensis). Although the Wallacea islands have lower species richness compared to the other large islands in Indonesia, they are rich in endemics, and the occurrence of invasive species would therefore threatened the ecological, economic and social balance of the regions. Several papers have hinted at the possibility of the invasion of Komodo National Parks by Asian toads, a situation which would potentially affect the survival of the Komodo dragon. To detect the presence of the invansive toad Duttaphrynus melanostictus in Komodo National Park and its surroundings areas we carried out an amphibian survey using a Visual Encounter Survey method during February to April 2018. The surveyed location consisted of two main islands within Komodo National Park (Rinca island and Komodo island), Flores island (Labuan Bajo and Cumbi village) and Sumbawa island (Sape). Two species of amphibians were found in Komodo National Park (Rinca island and Komodo island), while seven species of amphibians were found across all four locations. No D. melanostictus toads were found in Flores (including in Komodo National Park), however the toad was found to be abundant in Sape (Sumbawa island).

Abstract:

Compared with the direct access to the main power grid and diesel generators, this paper puts forward the scheme of using electric ships to shuttle between islands to transport electric energy, analyzes the limitations and defects of its application in offshore islands; and then puts forward a comprehensive energy supply system of offshore islands. The comprehensive energy supply system can make full use of the rich renewable energy of the islands, and realize the optimal allocation of the overall resources of the islands. At the same time, the energy supply system can break the isolated development pattern of island power grid and connect the island group power exchange ship. This paper analyzes the connotation and characteristics of the system, puts forward the key technology for building the integrated energy supply system of ocean island group, and gives the design and operation analysis example of power exchange ship.

Full text

Abstract:

A total of 74 ant species (from 23 genera) was recorded from 195 quadrats (50 × 50 m) from 39 continental islands off Arnhem Land, Northern Territory. In general, the ant fauna comprised generalist species widespread on the north Australian mainland. The functional group composition was also comparable to that of similar environments on the north Australian mainland. The ant fauna was not tightly structured. There were few habitat specialists, no species showed a clear preference for smaller islands, and only a few species showed unequivocal preferences for larger islands. There were no clear cases of congeneric, or otherwise ecologically similar, species replacing each other on different islands. In contrast to the north Australian mainland, there were no significant differences between habitats in ant species richness. However, the functional group composition varied significantly between the eight main habitats sampled across the islands, in a manner consistent with that reported for the mainland. The number of ant species recorded per island was most closely related to island size (80% of the deviance explained), but there was only slight or no relationship between island size and the number of species at the quadrat scale. Functional group composition varied between islands, with small islands supporting a relatively high proportion of Generalised Myrmicinae species. Low-lying (and presumably intermittently inundated) islands supported a higher proportion of Dominant Dolichoderinae and few Specialist Predators and Tropical Climate Specialist species. Very small islands supported a relatively high proportion of Dominant Dolichoderinae species. These differences are largely attributable to inter-island differences in habitat availability and disturbance regimes, and to differences between functional groups in dispersability, competitive ability and ecological flexibility. Species richness was little influenced by the extent of island isolation. Patterning in the ant fauna of these islands parallels that reported for islands elsewhere.

Abstract:

Settlement of pueruli of the Hawaiian spiny lobster, Panulirus marginatus, was monitored on a weekly to monthly basis during June 1979 – June 1985 at three islands situated across the extent of the Hawaiian Archipelago to define patterns of recruitment over the species' geographic range. Settlement occurred irregularly throughout the year at French Frigate Shoals near the center, but seasonally during reciprocal times of the year at Kure Atoll and Oahu located at opposite ends of the island chain. There were no significant long-term trends in monthly mean catch per collector. Settlement occurred primarily during the new moon and first quarter lunar phases at each island. The seasonal and geographic patterns of recruitment may be determined to a large extent by an island's position relative to the northern and southern boundaries of the North Pacific Central Water type. Seasonal changes in the position of the principal wind systems of the region, the trades and westerlies, also may influence these patterns. Settlement tended to be higher at the center of the archipelago than at either end and higher in the Northwestern Hawaiian Islands than around the main high islands. Regional differences in catch rates in the commercial fishery may be related to regional differences in puerulus recruitment. Settlement overall was low in comparison with spiny lobsters elsewhere.

Abstract:

The Pattern of Sea Transportation Network in the Region of Pangkajene and Islands Regency. Geographically, Pangkajene Islands Regency consist of land and islands, with a sea area of 11,464.44 km2, with 115 islands, 73 inhabited islands and 42 uninhabited islands. These conditions require a reliable sea transportation network to improve connectivity between the regional growth centers and the local growth centers. This study discusses the pattern of passenger movements, and plans for developing a sea transportation network system in the island cluster of Pangkajene Islands Regency using the method of cross classification analysis or category analysis to obtain the pattern of trip generation, as well as the gravity model analysis method for calculating the number of passenger movements. The results showed that, the high potential for passenger movement in the islands, but the availability of transportation networks and services is still low, identified several islands as the main economic center that serves as a hub port to connect the surrounding islands that function as feeders, including Balang Port Lompo and Sarappo Lompo Port in Liukang Tupabbiring District; Gondong Island Bali and Sabutung Island in Liukang Tupabbiring Utara District; Matalaang Port, Sapuka Lompo Harbor, and Sailus Harbor in Liukang Tangayya District; and Dewakang Lompo Port, Kalukalukuang Port and Pamantawang Port in Liukang Kalmas District.

Abstract:

This study mainly focused on the rainwater availability assessment in Turtle Islands Park, Sabah, Malaysia. Consisting of three small islands, this marine park is home to two endangered turtle species – Green and Hawkbills turtles. This special feature of the islands attracts tourist around the world, thus increasing the demand of freshwater supply for tourism development in the marine park. However, due to the shortage of freshwater from the ground due to salinity intrusion, rainwater is seen to be an alternative in fulfilling the freshwater demand. To evaluate the source of freshwater in these islands, information is obtained from the main users of the water source, which are the Sabah Park officers, the approved tour operator on the islands and the security forces. The rainwater tanks available on the islands are calculated to assess the storing capacity of rainwater. The water demand was estimated by multiplying the number of visitors with the average water usage per visitor. With the existing water tanks, this study found that the Turtle Islands Park has the ability to store 414 m3 of rainwater in Selingaan island, 3.2 m3 in Gulisaan island, and 102.1 m3 in Bakkungan Kechil island. However, the monthly water demand of each island exceeds the existing storage tanks, hence it is proposed that the number of rainwater tanks be increased to harvest as much rainfall as possible for the use of the islands’ inhabitants.

Abstract:

Raptor migration is complex phenomenon of migration which involving of millions of individual birds flying hundreds or thousands kilometers, between breeding habitat and wintering habitat. Migratory behavior consisted of period, route, and other aspects that affect the ecology of migratory birds. Pernis ptylorhynchus, Oriental honey-buzzard (OHB) is one of migratory raptors which have satellite tracked by ARGOS since 2003. Eastern part of Flores Islands consisted of small islands (23 islands) were identified as OHB’s migratory path to reach their wintering habitats in Kupang and Timor Island. This study has aimed to identify and analyze the OHB’s migratory behavior in Eastern part of Flores Islands. Four individuals OHB have satellite tracked in the period of 2007-2012 were used as main data for analyzing their migratory behavior. There was no particular pattern found on the way of OHBs selected islands for their stopover site because of the existence of small islands cluster provide variety of route for each OHBs. The length of their stay found relatively constant every year and tend to be stay longer on larger islands than the smaller one such as Flores Island and Lembata Island. This is apparently due to the larger islands provide more food supply than smaller islands.

Abstract:

In developing country like Malaysia, the development of islands is mostly related to the electric power availability. Because there are many islands in Malaysia where the power grid is not available. As an island surrounded by sea, wave energy can be considered one of the environmental friendly power generating sources for island communities. But, high dependency on weather conditions is the main drawback of wave energy source. To overcome this drawback; wave energy device, energy storage devices and the electronic converters need to be integrated with each other. This study presents a battery storage standalone oscillating water column wave energy conversion system for island electrification in Malaysia

Abstract:

The research aims to record the types of shark utilization in Selayar Islands Regency, explore the spread and shark status of the Regency of Selayar Islands, and examine the sustainability status of shark utilization by fisherman in Selayar Islands. The research method was based on the assessment of EAFM indicator assessments to assess the performance of shark resource management on Tarupa Island, Rajuni Island, Polassi Island and Kayuadi Island Selayar Islands Regency with an indicator approach involving two domains, i.e (1) Fish resources and (2) Fishing technique. The methods of obtaining the data were survey by extracting the data through interviews/questionnaire. The sample was determined using purposive sampling technique. The results of the research indicate that the status of utilizing shark fishery in Selayar Islands Regency is currently in medium category. The main issues indicated are a decrease in catch size and the catch of sharks that are not feasible to catch (50% of catch <Lm). The domains that need to get primary attention in the management of sharks fisheries are the domains of fish resources and fishing technique. The efforts of management carried out in each fields are based on central issues that emerge. Connectivity efforts between communities and institutions are needed to produce functional fisheries management status so that the sustainability of shark resources in Selayar Islands Regency can be sustainable

Abstract:

The energy costs of island systems are usually higher than those of large grid systems. Therefore, majority of the countries worldwide usually initiate their plans for developing renewable energy on remote islands. The electricity cost of Matsu Islands accounted for roughly 5% of total annual deficit of Taiwan Power Company. Hence, power generation is a critical energy economics issue for the Matsu Islands. This study will examine the possibility of wind power integration into Matsu Islands and investigate the transient frequency response in this system when a fault or disturbance occurs. According to the simulation results, the main target of this study is to improve the system stability on the remote island systems, and achieve the maximum renewable energy penetration.

Full text

Abstract:

Vegetation patterning is described for two neighbouring continental island chains off Arnhem Land, Australia. A total of 684 species was recorded from 57 islands, with reasonably comprehensive lists for 36 of these islands. Almost 90% of the deviance in plant species richness was associated with island size. The richness of plants dispersed by sea and/or vertebrates was proportionally greater on small islands; that of relatively poor dispersers was greater on larger islands. Twelve vegetation communities were defined by classification of plant species composition in 226 50 × 50-m quadrats. There was no relationship between island size and species richness at the quadrat level, at least for the most extensive vegetation types. The vegetation of the islands is now composed of two main elements—an original set of communities (mostly of heath, tussock grassland and eucalypt open forest) whose species have poor inter-island dispersal, and a set of more recent colonists (mostly of strand, mangrove and coastal thicket communities). The former group is allied to the sandstone flora of western Arnhem Land, but is species-poor in comparison, as the islands lack the deep gorges which drive much of the species richness of western Arnhem Land. The latter group comprises many species with a broad geographic range across tropical coastal areas, including many species which have been shown elsewhere to be highly vagile. Many species of the former set appear to have been lost from the smaller islands. The island flora has been influenced by three sets of human managers. Aboriginal use of the islands has been long-standing and probably resulted in a fire regime which may have accentuated environmental patchiness. Centuries of wet-season use of some islands by Macassan trepang-harvesters, ending early this century, has apparently left few effects other than the persistence of occasional small populations of an introduced food tree. In contrast, European use of these islands has been minimal and fleeting, but is associated with the introduction of most weeds.

Abstract:

The endemic moth genus Hyposmocoma (Lepidoptera: Cosmopterigidae) may be one of the most speciose and ecologically diverse genera in Hawaii. Among this diversity is the Hyposmocoma saccophora clade with previously unrecorded aquatic larvae. I present a molecular phylogeny based on 773 base pairs (bp) of the mitochondrial gene cytochrome c oxidase subunit I and 762 bp of the nuclear gene elongation factor 1-α. Topologies were constructed from data using maximum-parsimony, maximum-likelihood and Bayesian search criteria. Results strongly support the monophyly of the H. saccophora clade and the monophyly of the genus Hyposmocoma . The H. saccophora clade has single-island endemic species on Oahu, Molokai and West Maui. By contrast, there are three species endemic to Kauai, two being sympatric. The H. saccophora clade appears to follow the progression rule, with more basal species on older islands, including the most basal species on 11 Myr-old Necker Island, one of the Northwestern Hawaiian Islands. Aquatic behaviour either evolved recently in the species on the main Hawaiian Islands or was secondarily lost on the arid northwestern Necker Island. The phylogeny suggests that Hyposmocoma is older than any of the current main islands, which may, in part, explain Hyposmocoma 's remarkable diversity.

Abstract:

This paper is focused on research addressing a large quantity of data extracted from online reviews written by tourists visiting islands. These were extracted from TripAdvisor regarding island tourist destinations since there is a gap in the scientific literature using this approach on island tourism. The Islands of the Sun, Boa Vista and Sal, of Cape Verde, a Small Island Developing State (SIDS), were the targets of this investigation. After applying text mining to a large dataset, results are discussed, including from the perspectives of hotels, restaurants, and tourist attractions. For example, the beach is the main tourist attraction in both islands, but whereas in Boa Vista, tours on quad bikes constitute a major tourist activity, its equivalent in Sal is actually diving. The location of hotels near the beach is a big plus for tourists who also emphasize their human interaction with staff members in both hotels and restaurants.

Abstract:

High southern latitude island environments are unusual in having relatively low or, in some cases, no non-indigenous species (NIS). Here we describe the accidental transport and survivorship of moths (Lepidoptera, Noctuidae) on a research vessel travelling from southern South America (Montevideo, Uruguay) first to the cool temperate Falkland Islands and then onwards to Maritime Antarctic Signy Island (South Orkney Islands). On the vessel's arrival at Stanley, Falkland Islands, from Montevideo we found eight live (and 30 dead) individuals of two species of South American noctuid moth (Pseudaletia adultera Schaus and Peridroma saucia (Hübner)), presumed to have been attracted to the ship's lights while in port. Neither of these is indigenous to the Falkland Islands. Five of the eight living moths (all P. adultera) survived the four days the ship was moored in Stanley and one survived a further four day journey across the Polar Front to Signy Island. Southern oceanic islands are particularly vulnerable to invasion by NIS, with human (shipping) activities being the main route of arrival. With increasing shipping throughout this region some measures have been proposed or adopted to reduce the risk of NIS transfer.

Abstract:

SUMMARYExtinctions have altered island ecosystems throughout the late Quaternary. Here, we review the main historic drivers of extinctions on islands, patterns in extinction chronologies between islands, and the potential for restoring ecosystems through reintroducing extirpated species. While some extinctions have been caused by climatic and environmental change, most have been caused by anthropogenic impacts. We propose a general model to describe patterns in these anthropogenic island extinctions. Hunting, habitat loss and the introduction of invasive predators accompanied prehistoric settlement and caused declines of endemic island species. Later settlement by European colonists brought further land development, a different suite of predators and new drivers, leading to more extinctions. Extinctions alter ecological networks, causing ripple effects for islands through the loss of ecosystem processes, functions and interactions between species. Reintroduction of extirpated species can help restore ecosystem function and processes, and can be guided by palaeoecology. However, reintroduction projects must also consider the cultural, social and economic needs of humans now inhabiting the islands and ensure resilience against future environmental and climate change.

Abstract:

Seabird mortality associated with longline fishing in the eastern Bering Sea occurs mainly from September to May, with northern fulmars ( Fulmarus glacialis ) comprising the majority (60%) of the bycatch. Along the west coast of North America, winter dieoffs of fulmars may be increasing in frequency and magnitude, the most severe on record being a wreck that peaked in October–November 2003. We deployed satellite transmitters on fulmars from the four main Alaska colonies and tracked individuals for up to 2 years. Fulmars from Hall Island (northern Bering Sea) moved to Russian coastal waters after breeding, while Pribilof Island fulmars (southeastern Bering Sea) remained relatively sedentary year-round. Birds from Chagulak Island (eastern Aleutians) preferred passes between the Aleutian Islands in winter or foraged widely over deep waters of the central Bering Sea and North Pacific. Fulmars from the Semidi Islands (western Gulf of Alaska) migrated directly to waters of the California Current. Individuals from St. George Island (Pribilofs) and Chagulak were consistent in the places that they visited in two successive winters. The Pribilof Islands population is most affected by winter longlining for groundfish, whereas the Semidi Islands colony sustains most of the natural mortality that occurs off Washington, Oregon, and California.

Abstract:

Borneo is well known as a hotspot for biodiversity, yet species assemblages at smaller islands in the East Malaysian states of Sabah and Sarawak, are not well documented. The survey of frogs in Balambangan Island, which is situated at the west coast of Sabah, was the first attempt to look at the occurrence of frogs at smaller islands in the state. Sampling of frogs was conducted at the coastal areas of Kampung Selamat and limestone forest for four nights sampling period. Visual encounter survey and transect line were used to sample the frogs which were captured by hand. A total of seven species of 32 individuals were captured. This was only about 8% of the total species that occurs on the mainland Sabah. The island was dominated by the ranids (65%), rhacophoridae (22%) and microhylids (13%). Bufonids and megophryids were absent. The Mangrove frog, Fejervarya cancrivora (9 individuals) and the Lesser swamp frog, Limnonectes paramacrodon (8 individuals) were dominant on this island. No new species and endemism were noted on this island. The results from this preliminary study did not support the initial belief that the island contains high levels of endemism. On the contrary, the results appear to imply recent isolation from the Sabah mainland. Thus, a more detailed study including genetic diversity should be conducted to cover more areas on the main island and other smaller islands surrounding the Borneo Island and to obtain overall picture of biogeography of the frog species.

Abstract:

AbstractThe inquiry is focusing on why island autonomy occurs. Our point of departure considers four possible conditions such as geographical distance, ethnicity, GDP/capita and size according to population leading towards island autonomy. We use two sample groups in our study: one encompassing autonomous islands deriving from different parts of the world, with three main islands illustrating what we mean by island autonomy. These consist of the Azores, the Faroe Islands and Isle of Man. The second group consists of so called non-autonomous islands scattered around the world.The analysis is carried out with a specific technique within the Qualitative Comparative Analysis (QCA) family and that is Multi-Value QCA (MVQCA). MVQCA is an extension of the Crisp-Set QCA (CSQCA) and withholds a dichotomous dependent variable, while the possible explanatory variables (independent variables) can have multi-values. As a second technique Fuzzy-Set QCA (FSQCA) is employed as a control technique only. While assessing these techniques we receive combinations of conditions leading to the outcome in question. Results show that with MVQCA we receive four different paths towards island autonomy. Ethnicity as the only explanation is one route towards the outcome. A second path is small or large size. Long geographical distance combined with no ethnic diversity is a third way towards island autonomy. The fourth path is long geographical distance combined with the lower or upper middle income group. All the paths are equally valid.

Full text

Abstract:

Sardinia (Italy) and Corsica (France) are two islands divided by a strait that is 13 km wide. Their inhabitants have had commercial and cultural links at least since the Bronze Age, facing similar historical processes such as colonization from mainland powers during Middle Ages and a problematic assimilation within the nation-states to which the islands are nowadays associated. Nevertheless, they are generally perceived and analyzed as separate and distant islands. This is a consequence of the geopolitical context of the last three centuries, during which Corsica and Sardinia have become part of two separate states marked by a troubled relationship. This study has two main purposes: explaining the case of the two islands through a historical analysis of the island-to-island relationship between the 17th and 21st Centuries and proposing the concept of ‘impeded archipelago’ to describe analogous situations.

Abstract:

Angiostrongylus cantonensis is an emerging zoonotic nematode recognized as the leading cause of eosinophilic meningitis in the word. After its discovery in China, it was recorded in 30 countries worldwide. Recently, it has expanded to new areas such as South America and it has been recently found in the Atlantic island of Tenerife (Canary Islands). In order to characterize the distribution of A. cantonensis in the Canary Islands, the lungs of 1462 rodents were sampled in eight islands of the archipelago over 13 years and were then analyzed for A. cantonensis. Remarkably, the parasite was detected only in Tenerife, in Rattus rattus (19.7%) and Rattus norvegicus (7.14%). They were concretely in the northern part of the island, which had a warmer and more humid climate than the south and main cities. The absence of this nematode in other islands with similar environmental conditions could be explained by an isolation effect or by a recent introduction of the parasite in the islands. Besides, the presence in Tenerife of the most invasive lineage of A. cantonensis reinforced the hypothesis of a recent introduction on this island. This study highlights the need to implement control measures to prevent the expansion to other areas in order to avoid the transmission to humans and other animals.

Abstract This study aims at identifying the main obstacles to optimizing the provision of public services to the districts in the island areas and to discussing the prototype model of asymmetric decentralization in providing public services to the island areas. This study was conducted in three districts of small islands at the Tual city of Maluku province namely the districts of Kur Island, South Kur Island, and Tayando Tam island. The data were collected through triangulation of sources and methods. The informants were selected based on consideration of the position and competence of the required information. The methods were the in-depth interview, observation, documentation, and the Focus Group Discussion (FGD). The results showed that there were three main obstacles in providing public services to the districts in the island areas. Firstly, the partial authority of Mayor of Tual city had not given yet to the Head of Districts based on the Article 226 of Law No. 23 in 2014 about Regional Government. Secondly, the transportation for the islands was inadequacy and the natural conditions were challenging that obstructed the mobility of citizens to access the service center and it was difficult for officers to reach people who want to be served. Thirdly, the lack of resources (human resources, funds, and facilities) in some districts at the island areas. To overcome those problems, specific autonomous was required by island province that concerned different treatment settings to the districts within the island areas namely the expansion of authority, the increase in the position, and the development of resources and the organizational capacity and districts management.

Abstract:

A research survey for demersal finfish was completed using bottom trawl fishing gear, following a random stratified sampling design, between 50 and 500 m on shelf areas of subarea 48.1 (Elephant Island) and Subarea 48.2 (South Orkney Island). An acoustic survey was simultaneously carried out to enhance knowledge of bathymetry and the distribution of fish and krill in the studied area. The cruise took place between the 6 and 27 January 2018. A total of 36 hauls were carried out, 15 around Elephant Island and 21 around the South Orkney Islands. A total of 37 fish species were caught with a total biomass of 19,112 kg. The main species encountered included Notothenia rossii and Champsocephalus gunnari, with nominal catches weighing 16,204 (85%) and 876 kg (5%), respectively. Other species of fish accounted noticeably for lower amounts (11%), such as Gobionotothen gibberifrons (330 kg), Chaenocephalus aceratus (322 kg), and Pseudochaenichthys georgianus (299 kg). Indicative estimates of standing stock biomass suggested that in this cruise, N. rossii was the most abundant demersal finfish species in the Elephant Island area, followed by C. gunnari. Differently, on the South Orkney Islands shelf, the most abundant species was G. gibberifrons, followed by P. georgianus. The study provides biological data (length frequency distribution, median size, sex ratio, gonad maturity stages, length-weight relationship) on the main species captured during the survey, and the oceanographic characteristics (depth profiles of temperature, salinity, density) obtained with CTD around the South Orkney Islands.

Those records have been interpreted by some authorities as errors, or as reflecting occasional waifs rather than breeding populations. We now report an additional specimen of L. frontalis from the Loyalty Islands island of Maré, and we review distributional data for this species and for the closely allied L. saintgironsi. Sympatry on the western coast of Maré confirms that these two taxa warrant separate species status despite their minimal genetic divergence.

Abstract:

The first overview of the amphibians and reptiles of Dugi Otok Island, Northern Dalmatia, is presented, based on the published data and new records collected during the last twenty years. A total of 15 species are present on the island, of which only one was not recorded on our surveys. In comparison to other islands of Northern Dalmatia, Dugi Otok is the second most diverse island in terms of herpetofauna, just after Pag Island. The main threats to the amphibians and reptiles on the island are the disappearance and degradation of aquatic habitats, the abandonment and succession of traditional agricultural fields and olive groves and the increasing presence of several invasive species.

Abstract:

The McDonald Islands (53°S, 73°E) originally comprised three small islands that lie on the Kerguelen Plateau, 44 km west of Heard Island. No volcanic activity was observed since their discovery in 1874 until 1997, when two passing ships recorded major changes and eruptive behaviour. A 2001 satellite image showed that the main island had doubled its area. This paper reports observations made from a cruise ship in November 2002, supplemented by a high-resolution satellite image acquired in March 2003. A new volcanic complex comprises lava domes, spines and flows, all assumed to be phonolitic, similar to the older volcanic rocks. The complex shows dormant volcanic activity, with numerous fumaroles, recent spine evolution and lava flows. Changes in relative sea level have connected Flat and McDonald Islands. A spit about 1km long with extensive shoals beyond, now extends eastward from McDonald Island and presents new hazards to shipping. Biological changes include colonization by king penguins (Aptenodytes patagonica), previously absent, and a large reduction in numbers of formerly widespread macaroni penguins (Eudyptes chrysolophus chrysolophus).

Abstract:

Purpose Overall, there is a lack of research using online reviews as a proxy of customer experience when addressing the study of tourism in island destinations. Design/methodology/approach The current investigation aims to fill this gap by focussing on an African small island developing states, i.e. Cape Verde. This paper reports of tourist reviews extracted from TripAdvisor from “two islands of the senses” as coined by this archipelago’s national tourism organization, specifically Santo Antão and Fogo islands. The data analysis was performed through Leximancer software to generate concepts out of words, followed by themes. Findings The present research focussed on experiences in island tourism to identify their main dimensions based on visitors’ narratives in online reviews. The obtained results are of potential value to the literature by contributing to a better understanding of tourist experience in the context of tourism in islands in an understudied country, Cape Verde. Originality/value Results are presented and object of discussion vis-à-vis scientific literature and conclusions put forward in this journal paper.

Abstract:

O objetivo principal neste trabalho consistiu em analisar e comparar índices de (des) conforto térmico humano em um município de clima semiárido. Para isso foram adquiridos e utilizados equipamentos termo-higrômetros automáticos datalogger Akso AK170, sendo esses distribuídos espacialmente em onze pontos (dez em áreas urbanizadas e um em área rural), durante um período de 32 dias, em Caicó-RN. De posse dos dados horários de temperatura e umidade relativa do ar (maio/junho), realizaram-se análises estatísticas descritivas e aplicaram-se três índices de conforto humano, a saber: Índice de Desconforto (ID), índice de Temperatura Efetiva (TE), e o Índice de Temperatura e Umidade (ITU). Os resultados indicaram que o município de Caicó está propenso aos efeitos do processo de urbanização, registrando-se frequências de temperaturas mais elevadas nas áreas urbanizadas, especialmente nas de menor arborização e maior concentração de pavimentos urbanos. Em termos médios a maior parte da população de Caicó sente desconforto devido ao calor (ID), as temperaturas ficaram sempre acima do considerado calor moderado (TE) e de acordo com o ITU a classificação foi de extremamente desconfortável. Portanto, é imprescindível minimizar o os efeitos da ilha de calor no município a fim de se obter melhores índices de conforto térmico humano. Human (dis) comfort indices in a semi-arid municipality in Brazil A B S T R A C TThe main aim of this study was to analyse and compare the human thermal (dis)comfort indices in a Brazilian municipality with a semi-arid climate: Caicó, in the state of Rio Grande do Norte. Akso AK170 thermo-hygrometer data loggers were acquired for this purpose, which were distributed at eleven points in the study area – ten in built-up areas and one in a rural area – over a 32-day period covering the months of May to June. Having collected the time- and date-stamped temperature and relative humidity data, descriptive statistical analyses were conducted using three human comfort indices: discomfort index (DI), effective temperature index (ETI), and temperature-humidity index (THI). The results indicate that the municipality under study is affected by urbanization processes that propitiate higher temperatures in the built-up areas, especially where there are fewer trees and more of the roads are paved. On average, most of the population of Caicó feels discomfort because of the heat (ID), and the temperature always remains above the range rated as moderately hot (ETI). The municipal climate was classified as “extremely uncomfortable” by the THI. It is therefore of the utmost importance to minimize the effects of the heat island in the municipality to improve the human thermal comfort indices.Keywords: Urban climate. Caicó-RN.
