KALOUSOVA, ROMANA, e LADISLAV BOCAK. "Species delimitation of colour polymorphic Cladophorus (Coleoptera: Lycidae) from New Guinea". Zootaxa 4320, n. 3 (18 settembre 2017): 505. http://dx.doi.org/10.11646/zootaxa.4320.3.6.

Testo completo

Abstract (sommario):

Cladophorus Guérin-Méneville, 1830 are endemic Papuan net-winged beetles which take part in highly diverse Müllerian mimicry rings. Available specimens were sequenced for cox1–tRNA-Leu–cox2 mitochondrial DNA fragment and the species delimitations were based on the genetic distance, phylogenetic analysis, and morphology. Three earlier described species were identified in the recently collected material and further 10 species are described: C. pallescens sp. nov., C. bicolor sp. nov., C. craterensis sp. nov., C. motykai sp. nov., C. mindikensis sp. nov., C. kailakiensis sp. nov., C. manokwarensis sp. nov., C. haiaensis sp. nov., C. humeralis sp. nov., and C. boceki sp. nov. DNA-based identifications provided some ambiguous results and closely related species could not be robustly delimited using solely molecular data. Additionally, the species limits were based on clearly defined morphological characters and the morphological differentiation was found unlinked from the genetic divergence. Colour patterns cannot be used for identification because all species available in more specimens were polymorphic and followed various local co-mimics. The Papuan fauna of Cladophorus is very diverse and the closely related species regularly occur in limited regions. Differentiation within restricted ranges is therefore considered as the main speciation mode.

Testo completo

Abstract (sommario):

The genus Microcerotermes Silvestri is revised in an area covering New Guinea, the Bismarck Islands and the Solomon Islands. The presence and status of M. biroi (Desneux), M. papuanus Holmgren and M. repugnans Hill are confirmed. Microcerotermes brevior (Desneux), formerly treated as a subspecies or a synonym of M. biroi, is raised to specific rank. Microcerotermes piliceps Snyder, formerly considered a junior synonym of M. biroi, is recognised as valid; M. umbritarsus Hill and M. froggatti Hill are transferred from the synonymy of M. biroi to that of M. piliceps. The Australian species, M. taylori Hill, is reported from southern New Guinea. Four new species: M. luluai, sp. nov., M. cupreiceps, sp. nov.,M. bouilloni, sp. nov. and M. flyensis, sp. nov. are described. For each of the ten species recorded from our study area, all castes are described or redescribed, diagnostic characters are outlined, and a distribution map is given. Comparisons are also made with related species from adjacent regions. An identification key, based on the soldier and worker castes, is provided. We hypothesise that the New Guinean Microcerotermes fauna is of mixed Australian/southeast Asian origin.

Abstract (sommario):

Three species of Pleuranthodium were encountered and collected during a survey of gingers at Mount Wilhelm, Chimbu Province, Papua New Guinea. Based on new material, the only previously known Pleuranthodium from this area, P. piundaundense, is described in more detail highlighting new diagnostic characters and its known distribution range is expanded based on identification of older specimens at Edinburgh from two other provinces. Two species so far only known from Mount Wilhelm could not be identified after studying all protologues, types and material from several herbaria. These are here described as new species, P. corniculatum and P. sagittatum. A key with both floral and vegetative characters is provided to all three species. Pleuranthodium corniculatum is distinct in having apical appendages on the calyx, and P. sagittatum has a wrinkled calyx. All species are described and illustrated, and conservation assessments are made.

Abstract (sommario):

Fluorescent amplified fragment length polymorphism (F-AFLP) and microsatellites (SSRs) were used to evaluate new guinea impatiens (Impatiens hawkeri W. Bull) cultivars. Ninety-five quality-selected polymorphic fragments from 10 F-AFLP+3 primer combinations were used to evaluate 100 cultivars representing a variety of colors, forms, and breeding programs. Jaccard similarities and unweighted pair-group method of the arithmetic average (UPGMA) clustering formed a dendrogram with three cultivar groups, to a large extent clustering the cultivars by breeder with a high cophenetic correlation coefficient. A small insert genomic library was created and 442 kb of new guinea impatiens sequence was screened for repetitive motifs, resulting in 14 microsatellite markers. A subset of 46 cultivars representing five commercial breeding companies and 11 cultivar series was selected for microsatellite analysis. Seven loci were polymorphic, with two to six alleles per locus. Although both methods were equally effective in distinguishing the cultivars from one another, the topologies of the dendrograms for the two methods were different. The topology of the AFLP dendrogram reflected possible relationships based on cultivar series and breeding company, while the SSR dendrogram did not. The objectives of this research were to develop and validate both F-AFLP and SSR methodologies for new guinea impatiens, identify markers that can be reliably used for fingerprinting, and create a database for future cultivar comparisons.

Testo completo

Abstract (sommario):

In oilfield development and appraisal, a variety of tools are used to help define future reservoir performance. The identification of reservoir compartments, whether vertical or lateral, is a critical part of this evaluation. Reservoir compartments may develop over geologic or production timeframes depending on the characteristics of the reservoir seals. Frequently, the identification of some reservoir compartments is made only after the field is put on production.Reservoir pressure data is commonly used to identify reservoir compartments. A powerful complement to the pressure data are the properties of the reservoir fluids themselves. This provides a direct measure of hydrocarbon continuity. Both physical properties, such as gravity, bubble point pressure and GOR, and molecular properties of the oil are used. The detailed hydrocarbon composition of the reservoir fluids can be determined by a number of geochemical methods. In this paper we use capillary gas chromatography to generate oil fingerprints based on the molecular composition. We show how the oil fingerprint data is a sensitive discriminator of reservoir compartments.Reservoir studies of the Iagifu-Hedinia Field, Papua New Guinea, show the benefit of using a combination of geochemical, geological and engineering data. Each type of data reflects a different characteristic of the reservoir compartments. The combination of oil fingerprint and RFT pressure data demonstrated that some seals have been effective over geologic timeframes while others are effective only on a production timeframe. Geochemical data have also indicated the presence of reservoir compartments where other data were missing or inconclusive. Subsequently acquired production history data have confirmed the geochemically-based interpretations.

Abstract (sommario):

In 1959 Tokunaga recorded 26 species in the subgenus Forcipomyia from New Guinea, but he assigned no species to Lepidohelea, that subgenus being at the time considered of doubtful validity. Eleven of these species are here retained in subgenus Forcipomyia and five are transferred to Lepidohelea, which can now be more fully characterised (the remaining species are dealt with elsewhere in this series). Apart from the New Guinea material, a single species of subgenus Forcipomyia is known from Samoa, and one species described from Australia in 1889, F. albopunctata (Skuse), can also be assigned to subgenus Forcipomyia. In this paper 11 new species of subgenus Forcipomyia and 14 of subgenus Lepidohelea are described from Australia, and two new species of each subgenus from New Guinea. Additional data is presented for eight previously described species. Within each subgenus species have, where possible, been placed in species-groups to facilitate comparison and identification.

Abstract (sommario):

A key is provided to 13 species of Haplothrips recorded from Malesia, the tropical biogeographic region that extends from Peninsular Malaysia to New Guinea. Three new synonyms are established, and H. aliceae sp.n. is described from Sarawak, Timor-Leste and Thailand. In contrast to recent treatments of Haplothrips, one of the most common members of the genus in Australia, H. angustus Hood is recognised as a syn.n. of H. ganglebaueri Schmutz that is widespread from Iran to Indonesia. Difficulties in distinguishing between three of the most common flower-living, Southeast Asian, species of this genus are discussed: H. anceps Hood from northern Australia, H. chinensis Priesner from Hong Kong, and H. brevitubus (Karny) from Japan.

Testo completo

Abstract (sommario):

The species Tectaria nesiotica Holttum, described from New Guinea, is confirmed to be a member of the genus Pleocnemia and thus a new combination, P. nesiotica, is proposed here. It superficially resembles some species of Tectaria with large, finely dissected fronds and with veins anastomosing only along costae but differs in venation pattern. Within Pleocnemia, P. nesiotica is readily distinguished from other species by the blackish rachis and the sori confined to the apex of pinnule lobes. We fail to provide a key to all known species of Pleocnemia from New Guinea because for this group the species concept is currently very confusing, which was probably resulted from the incomplete herbarium specimens and the overemphasis of the character, sori indusiate or not, in recognizing species. Field observations are called for the clarification of species boundary in Pleocnemia.

Abstract (sommario):

The genera Hoplopisthius and Carcinopisthius are reviewed. All the species are redescribed and illustrated and an updated identification key and distributional maps are provided. One new species from New Guinea is described (Hoplopisthius maximus n. sp.) and two new synonymies are proposed: Hoplopisthius celebensis Kolbe, 1892 = H. trichemerus Senna, 1892, n. syn. and Carcinopisthius lamingtoni Damoiseau, 1987 = C. forcipitiger Damoiseau, 1987, n. syn. Phylogenetic analysis using PAUP (maximum parsimony) was performed using 25 morphological characters of adults. This analysis shows the group Hoplopisthius + Carcinopisthius is monophyletic, but Carcinopisthius alone is paraphyletic. Nomenclatural changes at the generic level are made to reconcile nomenclature and phylogeny: Hoplopisthius is preserved; Carcinopisthius is downgraded to the rank of subgenus for the two oriental species H. oberthueri and H. fruhstorferi; and Pseudotaphroderes is resurrected as a third subgenus and includes all New-Guinean and Australian species.

Abstract (sommario):

Commentary: The government of Papua New Guinea (PNG) has introduced a requirement for mobile phone registration. This commentary is a comprehensive analysis of the registration regulation, the process and key challenges. The paper is based on close observation of developments over several years, including attendance at court cases on the issue. The commentary includes: a description of the regulation, definitions of relevant terminology, a timeline of events, reflections on personal experiences, comparison to other countries, and discussion of related issues. In weighing costs against benefits, the author aims to determine the value of such a regulation. A key concern is the risk of poor and disadvantaged people being excluded from mobile phone ownership. While many countries in Africa and elsewhere have introduced similar requirements for registration with the stated objective of improving security, there is little evidence available that this measure does in fact reduce crime. Additionally, in Papua New Guinea, most people do not have any form of written identification documentation, which makes the process of mobile phone registration challenging.

Abstract (sommario):

This revision of the ‘quadrifasciculatus-group’ of Euops Schoenherr contains four previously described species for which lectotypes are designated: Euops bakewelli Jekel, E. corrugatus Lea, E. insularis Voss and E. quadrifasciculatus Lea. Six species are described as new: Euops goilala, sp. nov., E. hoppla, sp. nov., E. lakekamuensis, sp. nov., E. micros, sp. nov., E. oberprieleri, sp. nov. and E. reidi, sp. nov. Detailed descriptions are provided for all species, the characters relevant for their identification are illustrated, and a key for their identification is given. The group is known from Australia, New Guinea and the Kei islands of Maluku. The record of E. insularis Voss for Aru Island is not valid. Two Australian species (E. bakewelli and E. oberprieleri) are reported from Eucalypus host plants, one Papuan species (E. lakekamuensis) is known from another myrtacean host, and for the remainder of the quadrifasciculatus-group no host data are available. The sister-group of the quadrifasciculatus-group, the pygmaeus-group of New Guinea, feeds exclusively on Nothofagus. Three different scenarios are proposed, which could have led to the observed pattern of host association; they are discussed in the light of present knowledge on phylogeny and zoogeography of Euops.

Abstract (sommario):

Intrauterine infection is a major detriment for maternal-child health and occurs despite local mechanisms that protect the maternal-fetal interface from a wide variety of pathogens. The bacterial pathogenListeria monocytogenescauses spontaneous abortion, stillbirth, and preterm labor in humans and serves as a model for placental pathogenesis. Given the unique immunological environment of the maternal-fetal interface, we hypothesized that virulence determinants with placental tropism are required for infection of this tissue. We performed a genomic screen in pregnant guinea pigs that led to the identification of 201 listerial genes important for infection of the placenta but not maternal liver. Among these genes waslmrg1778(lmo2470), here namedinlP, predicted to encode a secreted protein that belongs to the internalin family. InlP is conserved in virulentL. monocytogenesstrains but absent inListeriaspecies that are nonpathogenic for humans. The intracellular life cycle ofL. monocytogenesdeficient ininlP(ΔinlP) was not impaired. In guinea pigs and mice, InlP increased the placental bacterial burden by a factor of 3 log10while having only a minor role in other maternal organs. Furthermore, the ΔinlPstrain was attenuated in intracellular growth in primary human placental organ cultures and trophoblasts. InlP is a novel virulence factor for listeriosis with a strong tropism for the placenta. This virulence factor represents a tool for the development of new modalities to prevent and treat infection-related pregnancy complications.

Abstract (sommario):

We reviewed the species-level classification of Metriorrhynchina net-winged beetles to make the group accessible for further studies. Altogether, 876 valid species are listed in a checklist along with known synonyms, combinations, and distribution data. The compilation of geographic distribution showed that Metriorrhynchina is distributed mainly in the Australian region with very high diversity in the islands at the northern edge of the Australian craton, i.e., in the Moluccas and New Guinea (54 and 423 spp. respectively). The neighboring northern part of the Australian continent houses a majority of known Australian species (112 spp.) and the diversity of net-winged beetles gradually decreases to the south (43 spp.). The fauna of Sulawesi is highly endemic at the generic level (4 of 10 genera, 67 of 84 spp.). Less Metriorrhynchina occur in the Solomon Islands and Oceania (in total 22 spp.). The Oriental Metriorrhynchina fauna consists of a few genera and a limited number of species, and most of these are known from the Philippines (51 of 94 Oriental spp.). We identified a high species level turn-over between all neighboring landmasses. The genus-level endemism is high in Sulawesi (4 genera) and New Guinea (11 genera), but only a single genus is endemic to Australia. During the compilation of the checklist, we identified some homonyms, and we propose the following replacement names and a new synonym: Metriorrhynchus pseudobasalis, nom. nov. for M. basalis Lea, 1921 nec M. basalis Bourgeois, 1911; Metriorrhynchus pseudofunestus, nom. nov. for M. funestus Lea, 1921 nec M. funestus (Guérin-Méneville, 1838), Trichalus pseudoternatensis, nom. nov. for T. ternatensis Kleine, 1930 nec T. ternatensis Bourgeois, 1900, Procautires subparallelus, nom. nov. for P. parallelus (Pic, 1926) nec P. parallelus (Bourgeois, 1883), and Cautires pseudocorporaali, nom. nov. for C. corporaali (Pic, 1921: 12), (formerly Odontocerus and Cladophorus) nec C. corporaali (Pic, 1921) (formerly Bulenides, later Cautires). Diatrichalus biroi Kleine, 1943, syn. nov. is proposed as a junior subjective synonym of D. subarcuatithorax (Pic, 1926). Altogether, 161 new combinations are proposed, and 47 species earlier placed in Xylobanus Waterhouse, 1879 transferred from Cautirina to Metriorrhynchina incertae sedis. The study clarifies the taxonomy of Metriorrhynchini and should serve as a restarting point for further taxonomic, evolutionary, and biogeographic studies.

Abstract (sommario):

Abstract. We present new radar-based techniques for efficient identification of surface changes generated by lava and pyroclastic flows, and apply these to the 1996 eruption of Manam Volcano, Papua New Guinea. Polarimetric L- and P-band airborne synthetic aperture radar (SAR) data, along with a C-band DEM, were acquired over the volcano on 17 November 1996 during a major eruption sequence. The L-band data are analyzed for dominant scattering mechanisms on a per pixel basis using radar target decomposition techniques. A classification method is presented, and when applied to the L-band polarimetry, it readily distinguishes bare surfaces from forest cover over Manam volcano. In particular, the classification scheme identifies a post-1992 lava flow in NE Valley of Manam Island as a mainly bare surface and the underlying 1992 flow units as mainly vegetated surfaces. The Smithsonian's Global Volcanism Network reports allow us to speculate whether the bare surface is a flow dating from October or November in the early part of the late-1996 eruption sequence. This work shows that fully polarimetric SAR is sensitive to scattering mechanism changes caused by volcanic resurfacing processes such as lava and pyroclastic flows. By extension, this technique should also prove useful in mapping debris flows, ash deposits and volcanic landslides associated with major eruptions.

Abstract (sommario):

Enterocytozoon bieneusi, an obligate intracellular microsporidian parasite, can infect humans and a wide variety of animals worldwide. However, information on the prevalence and molecular characterization of E. bieneusi in pet rats and guinea pigs is lacking. In this study, 325 fecal samples were collected from 152 pet fancy rats and 173 pet guinea pigs purchased from pet shops in Henan and Shandong provinces. The prevalence of E. bieneusi was 11.2% (17/152) in pet fancy rats and 20.2% (35/173) in pet guinea pigs. Genotypes D (n = 12), Peru11 (n = 3), S7 (n = 1) and SCC-2 (n = 1) were identified in pet fancy rats, and genotype S7 (n = 30) and a novel genotype PGP (n = 5) were identified in pet guinea pigs. The ITS sequence and its phylogenetic analysis showed that the novel genotype PGP was distinctly different; it exhibited less than 50% similarity to the reference sequences, and did not cluster with any of the known E. bieneusi genotype groups, forming a unique branch between groups 6 and 7. These data suggest that this is a new E. bieneusi genotype group. This is the first report of E. bieneusi infection in pet fancy rats and pet guinea pigs worldwide. The identification of zoonotic genotypes D, Peru11, and S7 suggests that pet fancy rats and guinea pigs can be potential sources of human microsporidiosis.

Abstract (sommario):

New Guinea tree kangaroos (Dendrolagus spp.) are unique arboreal macropodid marsupials mainly listed as critically endangered or endangered. The molecular systematics of Dendrolagus has not been fully resolved and is critical for the accurate identification of species and their evolutionary relationships. Matschie’s tree kangaroo (D. matschiei) and Goodfellow’s tree kangaroo (D. goodfellowi buergersi) share numerous morphological, physiological, and behavioural traits. We analysed the partial mitochondrial DNA cytochrome b gene for D. matschiei (n = 67), D. g. buergersi (n = 8), D. goodfellowi unidentified ssp. (n = 8), golden-mantled tree kangaroo (D. g. pulcherrimus; n = 1), and two additional New Guinea Dendrolagus taxa to determine whether D. matschiei and D. g. buergersi are sister taxa. D. matschiei and D. g. buergersi were not placed as sister taxa in our phylogenetic analyses; however, we were unable to analyse a known sample from a D. g. goodfellowi. We found initial genetic evidence that D. matschiei and the Lowland tree kangaroo (D. spadix) are sister taxa – they may have diverged after the formation of the Huon Peninsula of Papua New Guinea. Our results also support the elevation of D. g. pulcherrimus to a full species. An improved understanding of Dendrolagus molecular systematics will contribute substantially to their conservation.

Abstract (sommario):

Trichuriasis is the clinical disease of animals infected with the parasite of the genus Trichuris. This review attempts to present information on Trichuris spp. infestation in neo-tropical rodents that are utilized for meat consumption by humans. Neo-tropical rodents utilized for meat production can be divided into two categories: those that have been domesticated, which include the guinea pig (Cavia porcellus), and those that are on the verge of domestication, such as the capybara (Hydrochoerus hydrochaeris), lappe (Cuniculus paca/Agouti paca), and agouti (Dasyprocta leporina). This document reviews the literature on the species of Trichuris that affects the rodents mentioned above, as well as the clinical signs observed. The literature obtained spans over sixty years, from 1951 to 2020. Trichuris spp. was found in these neo-tropical rodents mentioned. However, there is a dearth of information on the species of Trichuris that parasitize these animals. The capybara was the only rodent where some molecular techniques were used to identify a new species named T. cutillasae. In most cases, Trichuris spp. was found in combination with other endoparasites, and was found at a low prevalence in the lappe and guinea pig. The presence of Trichuris spp. ranged from 4.62–53.85% in the agouti, 4.21–10.00% in the lappe, 50% in the capybaras, and 1–31% in guinea pigs. Further work must be done towards molecular identification of various Trichuris spp. present in these rodents, as well as the clinical effect of infection on the performance of agouti, lappe, capybara, and guinea pigs.

Abstract (sommario):

Information relating to the habitat, reproduction and diet is given for five murine rodents from the vicinity of Wau, Morobe Province, Papua New Guinea. Rattus steini was found to be present in all four habitats investigated (kunai, gardens, coffee plantations, forest), whereas R. exulans was absent from the forest; Melomys rufescens, M. lorentzi and Pogonomys macrourus were only trapped in the forest, and in low numbers. Although climatically similar to other montane regions in Papua New Guinea, the Wau area appeared to have an earlier start to the peak breeding season than elsewhere, and litter sizes seemed to be higher. The diet of Melomys species and P. macrourus appeared to be largely frugivorous (>90%), whereas Rattus species consumed a wide range of food items. While there was considerable overlap between the diets of Ratlus species, R. steini consumed more leafy material and insects, and less fruit, woody and vegetable material than R. exulans. Habitat modification by human activity in the Wau area has radically affected the diversity and relative abundance of rodent species, although it was difficult to discern any strong relationship between diet and habitat. While specific and generic identification of particular food items was not possible, an index of invertebrate diversity in the diet of rodents is suggested as a means of assessing changes in food availability, and therefore habitat change.

Abstract (sommario):

ABSTRACT Five Escherichia coli type 1 pilus mutants that had point mutations in fimH, the gene encoding the type 1 pilus adhesin FimH, were characterized. FimH is a minor component of type 1 pili that is required for the pili to bind and agglutinate guinea pig erythrocytes in a mannose-inhibitable manner. Point mutations were located by DNA sequencing and deletion mapping. All mutations mapped within the signal sequence or in the first 28% of the predicted mature protein. All mutations were missense mutations except for one, a frameshift lesion that was predicted to cause the loss of approximately 60% of the mature FimH protein. Bacterial agglutination tests with polyclonal antiserum raised to a LacZ-FimH fusion protein failed to confirm that parental amounts of FimH cross-reacting material were expressed in four of the five mutants. The remaining mutant, a temperature-sensitive (ts) fimH mutant that agglutinated guinea pig erythrocytes after growth at 31°C but not at 42°C, reacted with antiserum at both temperatures in a manner similar to the parent. Consequently, this mutant was chosen for further study. Temperature shift experiments revealed that new FimH biosynthesis was required for the phenotypic change. Guinea pig erythrocyte and mouse macrophage binding experiments using the ts mutant grown at the restrictive and permissive temperatures revealed that whereas erythrocyte binding was reduced to a level comparable to that of afimH insertion mutant at the restrictive temperature, mouse peritoneal macrophages were bound with parental efficiency at both the permissive and restrictive temperatures. Also, macrophage binding by the ts mutant was insensitive to mannose inhibition after growth at 42°C but sensitive after growth at 31°C. The ts mutant thus binds macrophages with one receptor specificity at 31°C and another at 42°C.

Abstract (sommario):

AbstractThe Old World screw-worm fly, Chrysomya bezziana Villeneuve, occurs in Africa, the Middle East, Malaysia, Indonesia and Papua New Guinea, but it is not found in Australia. Introduction into Australia from any of these source areas would threaten the viability of much of the grazing industry in the northern part of the continent. Proposed control by the sterile insect release method (SIRM) would be compromised by the existence of sibling species within C. bezziana. This study examines the degree of genetic differentiation throughout the extensive range of the fly to assess if the degree of geographic differentiation indicates the existence of sibling species and, allows identification of the source of any introduced flies. Electrophoretic analysis of 23 loci from samples collected in southern Africa, the Middle East, Malaysia, Indonesia, and Papua New Guinea revealed 11 polymorphic loci. Overall, populations show remarkably little divergence given the geographic distribution of sample sites. None of the populations sampled were fixed for alternative electromorphs. There is no evidence from this study for the presence of sibling species within C. bezziana.

Abstract (sommario):

The identity of Chelodina oblonga has been unclear because it has been variously defined to include populations of snake-necked chelid turtle from the southwest of Western Australia, across northern Australia, Cape York and southern New Guinea in its broadest conception, from just the northern part of this range (northern Australia and New Guinea), or restricted to the southwest corner of Western Australia in its narrowest conception. Uncertainty over the identity of the type specimens has added to the confusion. In this paper, we review the historical data on the extent of the type series of Chelodina oblonga, and its potential provenance, and find evidence that resolves some of the inconsistencies in previous literature on the identification of the type. Our analysis casts doubt on the northern Australian provenance of the type material. Hence, we return the name C. oblonga to the south-western species, in accordance with the genetic evidence for the provenance of the type in the Natural History Museum, London, and the external morphology of the type series. We designate a lectotype for the species, and redefine the subgeneric names that apply to the Australasian genus Chelodina, providing a new subgeneric name for one lineage.

Abstract (sommario):

This study provides the first detailed investigation of the catches of the shark longline fishery in Papua New Guinea. Fisheries observers collected data on shark catches from a total of 318 longline sets between May and June 2014, before its closure in July 2014. In all, 14694 sharks were recorded with a total estimated biomass of 439 tonnes (Mg). Eighteen species of sharks were recorded in the observer data, with the most dominant species being Carcharhinus falciformis, which constituted more than 90% of the total catches by both weight and number of individuals. The level of observer misidentification was low (<10%), which reflected the use of region-specific identification guides by well-trained fisheries observers. The most diverse catches were in the Solomon Sea area, whereas catches in most other areas, particularly the Bismarck Sea areas, were less diverse and more strongly dominated by C. falciformis. Size and sex ratios varied by species, highlighting the importance of obtaining species-level information from the fishery being investigated.
