The introduction of distributed generation (DG) onto distribution networks has a significant effect on losses and voltage profile. This effect cannot be characterized as detrimental or beneficial but is dependent on the allocation of DG on each distribution network section. Here the impact of DG on losses has been modeled, facilitating a unique approach to the allocation of DG. This approach has been implemented and tested on sample sections of distribution network and results are presented showing the optimal allocation of DG which improves the efficiency of energy delivery on the distribution network © 2012 Institut Teknologi Sepulul.

The boring giant clam, Tridacna crocea Lamarck, 1819, is a CITES-listed bivalve that is declining due to overharvest and environmental degradation. Previous molecular studies in the Coral Triangle using mitochondrial DNA indicated the presence of deep phylogenetic divergence and strong phylogeographic structure across this region, suggesting the possibility of multiple cryptic species. In the present study, we compare data from non-recombining mitochondrial (mtDNA; cytochrome oxidase subunit 1, COI) and eight microsatellite loci to better understand patterns of genetic structure and species boundaries in T. crocea populations across Indonesia and the Philippines. Microsatellite loci and mtDNA data from 618 individuals representing 27 populations revealed highly concordant phylogeographic patterns and identified three genetically distinct regions: (1) Western Indonesia, (2) Philippines and Central Indonesia, and (3) Eastern Indonesia. Both marker types also showed evidence of isolation by distance. These results build on previous studies and confirm the presence of only three genetic partitions and the genetic isolation of Western Indonesia and Eastern Indonesia. However, individual admixture analyses based on microsatellite data show that the mtDNA clade that defines a phylogeographic province spanning the Philippines and Central Indonesia is a mixture of unique genetic clusters from the Philippines/ Central Indonesia and Eastern Indonesia. The admixture of nuclear loci from individuals with regionally distinct mtDNA genomes suggests that despite deep genetic divisions, the three mitochondrial lineages are likely not distinct species and that some populations in Central Indonesia may be a sink for genetic diversity accumulated from populations to the north and east. While microsatellite data refined our understanding of the biology and evolutionary history of T. crocea, the broad concordance between these markers highlights the continued utility of mtDNA, particularly in developing biodiversity-rich countries where resources to support biodiversity science are limited.© 2014 Rosenstiel School of Marine and Atmospheric Science of the University of Miami.

While numerous population genetics studies have investigated phylogeographic patterns of coral reef organisms in the Coral Triangle, few have addressed whether fishes in the pelagic environment exhibit concordant patterns of genetic subdivision. We analyzed approximately 400 base pairs of the mitochondrial control region to compare population structure and phylogeography of five pelagic tuna and mackerel within a subset of their geographic ranges (i.e., the Indonesian Archipelago). Focal species include frigate tuna [Auxis thazard (Lacépède, 1800)], kawakawa [Euthynnus affinis (Cantor, 1849)], skipjack tuna [Katsuwonus pelamis (Linnaeus, 1758)], Indian mackerel [Rastrelliger kanagurta (Cuvier, 1816)], and narrow-barred Spanish mackerel [Scomberomorus commerson (Lacépède, 1800)]. Observed patterns of regional genetic subdivision were consistent with the role of Pleistocene vicariance in structuring populations. Divergence dates of all pelagic fish lineages dated to the Pleistocene epoch. Concordant barriers to larval dispersal found near Sumatra, Sulawesi, and Papua suggested that the Halmahera and Mindanao eddies and the Indonesian flowthrough may be contemporary forces maintaining genetic divergence between demes of pelagic fishes. Given the economic importance of these species, we suggest that the scale of management for pelagics in Indonesia be re-evaluated to reflect regional differences in the genetic composition of fishes.© 2014 Rosenstiel School of Marine and Atmospheric Science of the University of Miami.

Marine habitats are in decline worldwide, precipitating a strong interest in marine conservation. The use of biogeographic data to designate ecoregions has had significant impacts on terrestrial conservation efforts. However, classification of marine environments into ecoregions has only become available in the last several years, based on biogeographic data supplemented by geomorphology, ocean currents, and water temperatures. Here we use a comparative phylogeographic approach to test for concordant phylogeographic patterns in three closely related species of Tridacna giant clams across the Coral Triangle, the most biodiverse marine region in the world and one of the most threatened. Data from a 450 base pair fragment of mitochondrial cytochrome-c oxidase subunit one DNA from 1739 giant clams across Indonesia and the Philippines show strong concordance between phylogeographic patterns in three species of giant clams as well as evidence for potentially undescribed species within the genus. Phylogeographic patterns correspond broadly to marine ecoregions proposed by Spalding et al. (2007), indicating that processes contributing to biogeographic boundaries likely also limit genetic connectivity across this region. These data can assist with designing more effective networks of marine protected areas by ensuring that unique biogeographic and phylogeographic regions are represented in regional conservation planning.© 2014 Rosenstiel School of Marine and Atmospheric Science of the University of Miami.

The palm genus Areca is widespread in tropical Asia and includes the economically important betel nut palm, A.catechu. The genus has three centres of high species diversity: the Sunda Region, the Philippines and East Malesia (to the east of Wallace's line). The taxonomy of the genus in East Malesia has been neglected. Prior to this study, 19 species were accepted for this area, all but one endemic, but their limits and differences were not understood. Here, we provide a taxonomic monograph of East Malesian Areca spp., based on an extensive study of the genus in herbaria and in the field. We recognize six species of Areca in East Malesia, including the widespread cultivated A.catechu. Five wild species are accepted, namely A.macrocalyx, A.mandacanii, A.novohibernica, A.oxycarpa and A.vestiaria. We place 12 of the previously accepted species into synonymy, and provide additional new synonymy in A.catechu. © 2011 The Linnean Society of London.

Effective conservation strategies for highly migratory species must incorporate information about long-distance movements and locations of high-use foraging areas. However, the inherent challenges of directly monitoring these factors call for creative research approaches and innovative application of existing tools. Highly migratory marine species, such as marine turtles, regularly travel hundreds or thousands of kilometers between breeding and feeding areas, but identification of migratory routes and habitat use patterns remains elusive. Here we use satellite telemetry in combination with compound-specific isotope analysis of amino acids to confirm that insights from bulk tissue stable isotope analysis can reveal divergent migratory strategies and within-population segregation of foraging groups of critically endangered leatherback sea turtles (Dermochelys coriacea) across the Pacific Ocean. Among the 78 turtles studied, we found a distinct dichotomy in δ15N values of bulk skin, with distinct "low δ15N" and "high δ15N" groups. δ15N analysis of amino acids confirmed that this disparity resulted from isotopic differences at the base of the food chain and not from differences in trophic position between the two groups. Satellite tracking of 13 individuals indicated that their bulk skin δ15N value was linked to the particular foraging region of each turtle. These findings confirm that prevailing marine isoscapes of foraging areas can be reflected in the isotopic compositions of marine turtle body tissues sampled at nesting beaches. We use a Bayesian mixture model to show that between 82 and 100% of the 78 skin-sampled turtles could be assigned with confidence to either the eastern Pacific or western Pacific, with 33 to 66% of all turtles foraging in the eastern Pacific. Our forensic approach validates the use of stable isotopes to depict leatherback turtle movements over broad spatial ranges and is timely for establishing wise conservation efforts in light of this species' imminent risk of extinction in the Pacific.

BACKGROUND: Methane (CH4) produced during ruminal fermentation represents a loss of 10-11% of gross energy intake. The use of browse species containing tannin as feed supplement for ruminants tends to increase in order to reduce CH4 production. The present study was conducted to evaluate some tropical plants containing tannin as feed supplement (200 g kg1) on in vitro CH4 production and fermentation parameters. RESULTS: The crude protein (CP) content ranged from 87 to 390 g kg1 dry matter (DM) and was highest in Sesbania grandiflora (L.) Poiret. The neutral detergent fibre (NDF) concentration was highest in Pennisetum purpureum Schumach (725 g kg1 DM) and lowest in S. grandiflora (330 g kg1 DM). The ranking order of plants based on their total tannin content was Acacia mangium Willd. > Biophytum petersianum Klotzch > Jatropa curcas Linnaeus > Psidium guajava Linnaeus > Phaleria papuana > Persea americana Mill. > S. grandiflora. Methane gas production after 48 h of incubation was significantly (P < 0.05) lower with inclusion of A. mangium (PP + AM), B. petersianum (PP + BP), J. curcas (PP + JC) or P. guajava (PP + PG) as compared to control feed (PP). There was negative correlation between total tannin content and CH4 production at 48 h of incubation (r = 0.76). Concentration NH3-N was significantly (P < 0.01) higher with inclusion of S. glandiflora. Inclusion of P. guajava significantly (P < 0.05) suppressed protozoa population by 49.7% relative to control feed (PP). CONCLUSION: It was concluded that A. mangium, B. petersianum, J. curcas and P. guajava have potential to be used as a feed supplement to reduce CH4 production in ruminants. © 2009 Society of Chemical Industry.

Patterns of plural marking and numeral modification in Indonesian provide an interesting test bed for theories of the semantics of numeral classifiers and plurality. Cross-linguistically, the presence of numeral classifiers in a language is strongly connected with the absence or optionality of plural marking; this generalization is the basis of Chierchia's (1998a, 1998b) nominal mapping parameter and also accords with established typological generalizations (Greenberg, 1972), (Aikhenvald, 2000), (Corbett, 2000). In Indonesian, plural marking as both reduplication and classifiers in numeral modification constructions are optional, and bare (non-reduplicated) Indonesian nouns are best analysed as exhibiting general number (Greenberg, 1972), (Carson, 2000), (Corbett, 2000), rather than corresponding to the unmarked member of a singular-plural opposition. Unlike many languages with general number, Indonesian exhibits no mass-count distinction: notionally 'mass' and notionally 'count' nouns do not differ in their grammatical behaviour and participate equally in reduplication and numeral modification constructions. We provide an analysis of the semantics of reduplication, classifiers, and numeral modification in Indonesian which rests on the lack of a mass-count distinction and explains the strong dispreference for numeral modification of reduplicated nouns. © The Author 2011.
