Monitoring for Persistent Organic Pollutants (POPs) in Fiji’s environment

Recently there has been a global concern on Persistent organic pollutants due to its negative effects on environment and human health. Despite this, very little scientific data exists from small island developing states (SIDs). Project POPS is about an investigation into a toxic cocktail of POPs chemicals that poses a threat to human population and our environment.


Determining folate content in some Fijian foods.

Folate is the general name given to this group of water-soluble B9 vitamins that perform similar tasks but differ from each other in their structure. Folate derivatives play very important roles in the body. It’s most important role is as carriers for one –carbon units required for important metabolic pathways. Folate is also involved in the synthesis of RNA and DNA.

Determination of trends in the ambient air Persistent Organic Pollutants (POPs) concentrations in the Pacific Islands Region using polyurethane foam based passive air samplers.

The project involves the use and application of polyurethane foam disks (PUFs) as an air filter in the determination of the concentrations of POPs in ambient air. Emphasis is placed on the evaluation of the impact of the local primary point sources, secondary and diffusive sources as well as the long range transport (LRT) of these organic compounds.


Levels of persistent organic pollutants and 2,2,4,4,- tetrabromodiphenylether (PBDE No. 47) in freshwater mussels (Batissa violacea) (kai) in Fiji Rivers and seawater shellfish Anadara antiquata (kaikoso) in Fiji coastal waters.

The research project involves a detailed investigation on the contamination of rivers and coastal waters of Fiji of POPs and PBDEs by the use of freshwater mussels and seawater shellfish as bio-indicators. These mussels and shellfish were chosen as bio-indicators since these were valuable daily food for coastal.rivers-side dwellers and also a major source of daily earnings for most Fiji families.

The Analysis of the Antibiotic Activities of Salinispora Strains from Marine Sediment as a Guide to New Phylogenetic and Chemical Diversity.

The Actinomycete group of bacteria are known to produce antitumor, immune suppressive agents and enzymes (Lam, 2006) and also antibiotic compounds. The genus Salinispora belonging to the actinomycete family Micromonosporaceae, has been found to contain highly potent anticancer compounds, an example of which is Salinisporamide A produced by S. Tropica currently in stage II clinical trials. Only 3 species have been found so far namely S. tropica, S. arenicola and S. pacifica, with each of them producing distinctive compounds. Thus, hypothetically one could discover new Salinispora species by looking for strains that make new metabolites at the Salinispora genus level.

Trunk-inhabiting bryophyte diversity on two common native trees along an altitudinal gradient on Viti Levu, Fiji.

Fiji has a rich biodiversity in tropical wet forests on high oceanic islands in the Pacific. This rich and distinct biodiversity includes the mosses, liverworts and hornworts, collectively known as bryophytes. This research focused on the ecology of bryophytes on the lower trunks of two host tree species and is the first of its kind for Fiji.

This project analyses several mechanisms affecting the abundance, diversity and community structure of fish in wadable streams of Nakorotubu district, on the island of Viti Levu, Fiji.


Diversity and community structure of macro-moths (Lepidoptera) in lowland forest habitats on Viti Levu, Fiji.

The Fiji Islands are a biodiversity hotspot with a large proportion of their flora and fauna being endemic. Over the last 200 years since the colonial era taxonomic studies have been conducted and a relatively large proportion of the country’s biodiversity has been documented. However, more detailed information on distribution and population structure of some taxa remains virtually unknown.


Distribution and abundance of the Fijian ground frog (Platymantis vitianus) and the cane toad (Chaunus [Bufo] marinus) on Viwa Island, Tailevu, Fiji.

The cane toad, Bufo marinus, was introduced to the Fiji Islands by the Fiji Agriculture Department in 1936 as a biological control agent. Although extirpations of the endemic Fiji Ground Frog (FGF) have been attributed to the introduced small Indian mongoose (Herpestes javanicus eradication project, therefore the results of this study will provide valuable baseline information on areas to target for cane toad removal and ) the cane toad (CT) has also recently been proposed as a potential agent of decline.


Diversity distribution and abundance of Fijian freshwater fish

One of the poorly known aspects of the biodiversity of the Fijian Islands is the biodiversity of freshwater fauna. Data collected from this study were used to compile a checklist of Fijian freshwater and estuarine fish, determine the physical habitat factors influencing richness and abundance and identify biogeographic patterns including fish communities and assemblages found in different regions and habitat.


Conservation, management and ethnobotany of Sago (Metroxylon vitiense) in South-East Viti Levu, Fiji Islands

Monitoring comparative spatial and temporal variation in the land-birds of Vago-Savura Forest Reserve, a native lowland rainforest in south east Viti Levu, Fiji.

Birds are an important indicator species and part of Fiji’s Natural Heritage. As most bird surveys conducted in Fiji to date were qualitative, very little is known about the ecology, population abundance and seasonality of many of Fiji’s land birds. The purpose of this study was to identify a pattern of seasonality in the detected abundance of the native land birds in the Vago-Savura Forest Reserve.


Taxonomy, host-selection, biogeography and species distribution modelling of the Fijian long-horned beetles (Coleoptera: Cerambycidae)

Long-horn beetles (Family: Cerambycidae) in Fiji includes 124 described species within 45 genera of which 110 (88.7%) are considered endemic. Cerambycids serve as pollinators and decomposers and are considered important providers of ecological services. The family also contains an iconic Fijian species – the giant long-horned beetle Xixuthrus heros Heer 1868, one of the largest beetles in the world and a cultural totem for the chiefly clan of the Namosi Province.


Taxonomy, diversity and distribution of canopy Coleoptera (Beetles) along elevational gradients on Eastern Viti Levu, Fiji.

Ecological gradients (e.g. habitat types, climate, altitude, seasonality etc.) are known to be important factors in regulating the diversity and distribution of insect taxa. Knowledge of their distribution patterns is essential for proper conservation measures to be implemented. In Fiji, virtually no studies of this type have been done. In this study, canopy coleopteran communities were surveyed along a landscape transect on selected undisturbed rainforest areas in eastern Viti Levu, Fiji from lowland Nakobalevu (200m) through upland Waisoi to a cloud montane forest in Monasavu (1000m).
