Recent species in old Islands : the origin of introduced populations of Litoria aurea (Anura : Hylidae) in New Caledonia and Wallis

New Caledonia is a megadiverse tropical island in the southwest Pacific, however, inhabited by only one species of amphibian, Litoria aurea (Hylidae). We used both molecular (CO1 and ND4 gene sequencing) and morphometric data to explore its geographi...

Structure and development of the southeast Newfoundland continental passive margin: derived from SCREECH Transect 3

P>New seismic reflection data from the Grand Banks of Newfoundland and the Newfoundland Basin add to the growing knowledge of the composition, structure and history of this non-volcanic margin. Geophysical imaging is now approaching the extent of tha...

Intermediate water flows in the western South Pacific : as revealed by individual Argo floats trajectories and a model re-analysis

Thanks to the autonomous Argo floats of the OUTPACE cruise (Oligotrophy to UlTra-oligotrophy PACific Experiment) and of the THOT (TaHitian Ocean Time series) project, some features of intermediate-flow dynamics, at around 1000 m depth, within t...

Plant species microendemism and conservation of montane maquis in New Caledonia : two new species of Pancheria (Cunoniaceae) from the Roche Ouaieme

Two species of Pancheria (Cunoniaceae) described here, Pancheria minima J.C. Bradford and Pancheria ouaiemensis J.C. Bradford, draw attention to a recently recognized biodiversity pattern in New Caledonia. Montane maquis on acidic substrates, especia...

Impact of Austropuccinia psidii in New Caledonia, a biodiversity hotspot

Myrtle rust, caused by the fungus Austropuccinia psidii, infects a wide range of host species within the Myrtaceae family worldwide. Since its first report in 2013 from New Caledonia, the extent of the host range, geographical distribution and geneti...

Rain-derived particles and CDOM distribution along the east coast of New Caledonia

Shortly after strong rains or tropical storms, chlorophyll-a concentration (Chla), turbidity, and colored dissolved organic matter (CDOM) in the lagoon of New Caledonia may be tripled. This effect is visible as far as 50 km offshore. The Eastern Coas...

Microbial island biogeography: Isolation shapes the life history characteristics but not diversity of root-symbiotic fungal communities

Island biogeography theory is one of the most influential paradigms in ecology. That island characteristics, including remoteness, can profoundly modulate biological diversity has been borne out by studies of animals and plants. By contrast, the proc...

Comparative adult preference–larval performance relationship between a specialist and a generalist tephritid: Implication for predicting field host-...

Phytophagous insects differ in their degree of specialization to their host plants. It ranges from monophagous or oligophagous species that can only develop on a single host plant, or family of host plants, to extremely polyphagous species that can d...

Atlas de Nouvelle-Calédonie - Hydrométrie

Cet article relate les informations relevées au travers du réseau de mesures géré par les services du gouvernement (22 stations). Il fournit des éléments sur les différents régimes hydrologiques, les étiages ainsi que les crues et inondation...
