Although the French Polynesian reefs are among the most well studied reefs of the world, sponges are still poorly known, with only 199 species or OTUs of sponges having been described from French Polynesia, 167 at an OTU level and 32 at a species level. From those 199 species, just five are calcareous sponges. As it is possible that this number is underestimated, the aim of the present work was to study the diversity of calcareous sponges from French Polynesia. Hence, different French Polynesian archipelagos were surveyed by SCUBA from 3 to 60 m of depth. Identifications were performed using morphological and molecular (ITS and C-LSU) tools. We found a total of nine species of Calcarea, comprising five different genera. Five species are new to science: Clathrina fakaravae sp. nov., Clathrina huahineae sp. nov., Ernstia variabilis sp. nov., Leucascus digitiformis sp. nov., and Leucandra tahuatae sp. nov. With the present work, the number of identified sponges from French Polynesia at a species level increased from 32 to 41. The only calcareous sponge previously known from French Polynesia that was recollected by our group was Leucetta chagosensis. Our results suggest that the Eastern Indo-Pacific Realm shows more affinity with the Central and the Western Indo-Pacific Realms. Four species supported these affinities: Ascandra cf. crewsi, previously known only from Papua New Guinea, Leucascus simplex from South Australia, and Leucetta chagosensis and L. microraphis, both widespread species in the Indo-Pacific. These two Leucetta species, however, most likely represent species complexes. Once again the molecular markers ITS and C-LSU helped in the identification of calcareous sponges, showing how important is an integrative taxonomy. Although our work has increased in 250% (6 spp to 15 spp) the diversity of calcareous sponges in French Polynesia, it is most possible that this number is still underestimated.

Abstract Russelia equisetiformis is a shrub that is widely cultivated around the world (PROTA. 2016). It is listed as an invasive and a transformer species in Cuba (Oviedo Prieto et al., 2012). In Oceania it is reported as an invasive species that has escaped from cultivation in Fiji, French Polynesia, Kiribati, New Caledonia, Niue and Palau (PIER, 2016). In Florida it is regarded by Florida's Exotic Pest Plant Council as a category III species; a widespread species that has the potential to form dense monocultures, primarily on disturbed sites (FLEPPC, 1993). It is regarded as a low risk species in Hawaii (Bezona et al., 2009).

Abstract M. umbellata is a climbing weed widely distributed in tropical regions throughout the world. It is one of the commonest and most widespread species of Merremia. Due to its attractive yellow flowers, it has been introduced as an ornamental in several countries where has become naturalized. It is typically found in disturbed areas and as a weed in agricultural crops and plantations, but little is known about its environmental impact. The PIER website (PIER, 2016) lists it as invasive in Hawaii, Fiji, Micronesia, French Polynesia, New Caledonia and the Galápagos Islands, although regional floras and reports (see references in the distribution table) do not explicitly indicate so. It is also considered invasive in Cuba (Oviedo Prieto et al., 2012) and American Samoa (Speith and Harrison, 2012).

Shallow-water and littoral tanaids from the Southern French Polynesia Expedition, 2014 to Rapa Iti, Morane, Taravai and Mangareva, were examined with the tanaidomorphs represented by nine taxa, four of them described as new species within the genera Chondrochelia, Poorea, Triparatanais, and Zeuxoides. A new paratanaid genus is established, Periparatanais n. gen., and Nobili’s Tanais seurati is rediscovered and redescribed as a species distinct from the Hawai’ian Zeuxo insularis n. comb. A broad comparison of tanaid faunas across the Polynesian and eastern Indo-Pacific regions based on the Marine Ecosystems of the World (MEOW) classification shows almost no species-level correspondences but several genera within four apseudomorphan and three tanaidomorphan families are consistently present.

Pests have been a constant threat to agriculture the world over. In the Fiji Islands where the major agricultural export commodity is raw sugar, the Sugarcane weevil borer is one such agricultural pest that poses a real threat to an already ailing industry. The Sugarcane weevil borer (Rhabdoscelus obscure) is a pest originally found in Papua New Guinea whose introduction into Fiji has resulted in crop damage particularly to the soft variety of sugarcane found in Fiji. This review highlights the emergence of the weevil borer and explains a possible control that could be implemented by the Fijian farmers. The current method of control in Fiji uses the split billet trap. While this method has been recognized as an economically viable method of controlling the spread of the weevil borer, it has not been completely effective in eradicating the pest. This paper highlights and puts forth recommendations on other methods which could be used by the sugarcane industry.

AbstractCaenorhabditis elegans has become one of the most widely used model research organisms, yet we have little information on evolutionary processes and recent evolutionary history of this widespread species. We examined patterns of variation at 20 microsatellite loci in a sample of 23 natural isolates of C. elegans from various parts of the world. One-half of the loci were monomorphic among all strains, and overall genetic variation at microsatellite loci was low, relative to most other species. Some population structure was detected, but there was no association between the genetic and geographic distances among different natural isolates. Thus, despite the nearly worldwide occurrence of C. elegans, little evidence was found for local adaptation in strains derived from different parts of the world. The low levels of genetic variation within and among populations suggest that recent colonization and population expansion might have occurred. However, the patterns of variation are not consistent with population expansion. A possible explanation for the observed patterns is the action of background selection to reduce polymorphism, coupled with ongoing gene flow among populations worldwide.

Abstract Among Antarctic amphipods of the genus Eusirus, a highly distinctive clade of giant species is characterized by a dorsal, blade-shaped tooth on pereionites 5–7 and pleonites 1–3. This lineage, herein named ‘crested Eusirus’, includes two potential species complexes, the Eusirus perdentatus and Eusirus giganteus complexes, in addition to the more distinctive Eusirus propeperdentatus. Molecular phylogenies and statistical parsimony networks (COI, CytB and ITS2) of crested Eusirus are herein reconstructed. This study aims to formally revise species diversity within crested Eusirus by applying several species delimitation methods (Bayesian implementation of the Poisson tree processes model, general mixed Yule coalescent, multi-rate Poisson tree processes and automatic barcode gap discovery) on the resulting phylogenies. In addition, results from the DNA-based methods are benchmarked against a detailed morphological analysis of all available specimens of the E. perdentatus complex. Our results indicate that species diversity of crested Eusirus is underestimated. Overall, DNA-based methods suggest that the E. perdentatus complex is composed of three putative species and that the E. giganteus complex includes four or five putative species. The morphological analysis of available specimens from the E. perdentatus complex corroborates molecular results by identifying two differentiable species, the genuine E. perdentatus and a new species, herein described as Eusirus pontomedon sp. nov.
