Thermotolerance adaptation to human-modified habitats occurs in the native range of the invasive ant Wasmannia auropunctata before long-distance dispe...

Key evolutionary events associated with invasion success are traditionally thought to occur in the introduced, rather than the native range of species. In the invasive ant Wasmannia auropunctata, however, a shift in reproductive system has been demon...

Biodiversity of Mimosa pudica rhizobial symbionts (Cupriavidus taiwanensis, Rhizobium mesoamericanum) in New Caledonia and their adaptation to heavy m...

Rhizobia are soil bacteria able to develop a nitrogen-fixing symbiosis with legumes. They are taxonomically spread among the alpha and beta subclasses of the Proteobacteria. Mimosa pudica, a tropical invasive weed, has been found to have an affinity ...

Transcriptome data from three endemic Myrtaceae species from New Caledonia displaying contrasting responses to myrtle rust (Austropuccinia psidii) [Da...

The myrtle rust disease, caused by the fungus Austropuccinia psidii, infects a wide range of host species within the Myrtaceae family worldwide. Since its first report in 2013 in New Caledonia, it was found on various types of native environments whe...

Circadian behaviour of Tectus (Trochus) niloticus in the southwest Pacific inferred from accelerometry

Background: Behaviour and time spent active and inactive are key factors in animal ecology, with important consequences for bioenergetics. For the first time, here, we equipped the gastropod Tectus (= Trochus) niloticus with accelerometers to describ...

Metabolomic variability of four macroalgal species of the genus Lobophora using diverse approaches

Among comparative metabolomic studies used in marine sciences, only few of them are dedicated to macroalgae despite their ecological importance in marine ecosystems. Therefore, experimental data are needed to assess the scopes and limitations of diff...

Application of the support vector regression method for turbidity assessment with MODIS on a shallow coral reef lagoon (Voh-Kone-Pouembout, New Caledo...

Particle transport by erosion from ultramafic lands in pristine tropical lagoons is a crucial problem, especially for the benthic and pelagic biodiversity associated with coral reefs. Satellite imagery is useful for assessing particle transport from ...

Suivi environnemental Rapport annuel 2011 CAPTAGES

Le procédé de traitement hydrométallurgique employé par Vale Nouvelle-Calédonie requiert un apport journalier d'eau important ; la solution retenue a été de capter les eaux du lac de Yaté pour répondre à ce besoin. Les eaux sont utilisées ...

Écosystème d'eau douce - Partie I : Caractérisation de l'état initial, Janvier 2005 - Partie II : Stratégies d'échantillonnage et bio-indicateur...

Synthèse de l'état des connaissances sur les milieux d'eau douce en Nouvelle-Calédonie. Une première partie présente les milieux aquatiques rencontrés en Nouvelle-Calédonie ainsi que les habitats qui y sont associés et les stress qui s'exerce...
