Photo-identification confirms that humpback whales (Megaptera novaeangliae) from eastern Australia migrate past New Zealand but indicates low levels o...

Recent photo-identification and genetic studies have identified at least five discrete breeding populations in Australia and Oceania: western Australia (D), eastern Australia (E (i)), New Caledonia (E (ii)), Tonga (E (iii)), French Polynesia and the ...

Structural and floristic diversity of mixed tropical rain forest in New Caledonia : new data from the New Caledonian Plant Inventory and Permanent Plo...

Aims: To describe the structural and floristic diversity of New Caledonian mixed tropical rain forest and investigate its environmental determinants. Location: New Caledonia (SW Pacific), a biodiversity hotspot. Methods: Structural (stem density, bas...

Evaluation of transgenerational isotope labeling of embryonic otoliths in a coral reef damselfish with single and repeated injections of enriched (137...

Quantifying the larval dispersal component of population connectivity is extremely challenging due to the many difficulties associated with directly observing larvae in their marine environment. Transgenerational isotope labeling is a recent empirica...

Accounting for the indirect area effect in stacked species distribution models to map species richness in a montane biodiversity hotspot

Aim Understanding how species richness is distributed is a critical prerequisite to implement efficient conservation strategies in biodiversity hotspots. Stacked species distribution models (S-SDMs) provide new opportunities to map species richness, ...

Heterotrophic bacterial production and metabolic balance during the VAHINE mesocosm experiment in the New Caledonia lagoon

Studies investigating the fate of diazotrophs through the microbial food web are lacking, although N-2 fixation can fuel up to 50% of new production in some oligotrophic oceans. In particular, the role played by heterotrophic prokaryotes in this tran...

Socioeconomic and environmental determinants of dengue transmission in an urban setting : an ecological study in Noumea, New Caledonia

Background Dengue is a mosquito-borne virus that causes extensive morbidity and economic loss in many tropical and subtropical regions of the world. Often present in cities, dengue virus is rapidly spreading due to urbanization, climate change and in...

Correlations between leaf toughness and phenolics among species in contrasting environments of Australia and New Caledonia

Background and Aims: Plants are likely to invest in multiple defences, given the variety of sources of biotic and abiotic damage to which they are exposed. However, little is known about syndromes of defence across plant species and how these differ ...

Structural and floristic diversity of mixed tropical rain forest in NewCaledonia: Newdata from the New Caledonian Plant Inventory and Permanent Plot N...

Aims To describe the structural and floristic diversity of New Caledonian mixed tropical rain forest and investigate its environmental determinants. Location New Caledonia (SW Pacific), a biodiversity hotspot. Methods Structural (stem density, basal ...

Environmental correlates for tree occurrences, species distribution and richness on a high-elevation tropical island

High-elevation tropical islands are ideally suited for examining the factors that determine species distribution, given the complex topographies and climatic gradients that create a wide variety of habitats within relatively small areas. New Caledoni...

Carbonation and silicification of the New Caledonia peridotite Nappe: a stable isotope survey

The ophiolite of New Caledonia (Southwest Pacific), known as the Peridotite Nappe, has been subject to tropical weathering since its emersion during the Oligocene. Silica veins at the base of the weathering profile and magnesite veins along the serpe...
